Bipolar disorder (BP) in youth is an impairing psychiatric disorder associated with high rates of relapse and recurrence. High rates of psychiatric and medical co-morbidities account for additional illness burden in pediatric BP. The elevated risk of overweight and obesity in this population is of particular concern. One of the likely etiologies for weight gain in youth with BP is use of mood-stabilizing medications. Although these medications can be effective for mood stabilization, excessive weight gain is a common side effect. Obesity is associated with a host of medical problems and is also correlated with worse psychiatric outcomes in BP, rendering the prevention of weight gain in this population particularly clinically relevant. In this article, we describe the rationale and development of a brief motivational intervention for preventing weight gain among youth with BP initiating mood-stabilizing pharmacological treatment and then present a case example illustrating the principles of the intervention.

Study Objectives: To examine the feasibility, acceptability, and impact of a Sleep Promotion Program (SPP)., Methods: This pilot trial randomized adolescents (13-15y) with insufficient sleep duration and irregular sleep timing to SPP-continuation (n=24; SPP in month 1, continuation treatment in month 2) or monitoring-SPP (n=20; monitoring in month 1, SPP in month 2). SPP included one clinician session and at-home delivery of web-based reports of each youth's sleep diary data with accompanying intervention questions that prompt youth to engage in sleep behavior change. Attrition rate primarily measured feasibility. Program satisfaction measured acceptability. Total sleep time (TST), sleep timing, and sleep timing regularity were measured via sleep diary at baseline, follow-up 1, and follow-up 2 (each ∼1 month apart). Linear mixed effects models compared treatment arms on changes in sleep from baseline to follow-up 1 (month 1). We also compared changes in sleep during month 1 to changes in sleep during month 2 among SPP-continuation participants., Results: Attrition rate was 8.5%. 96.5% participants rated the quality of care received as good or excellent. In month 1, SPP-continuation youth showed a significantly greater increase in mean TST than monitoring-SPP youth (0.57 vs. -0.38 hours; contrast=0.95; CI =0.14, 1.76, p =0.024). SPP-continuation participants showed an increase in TST during month 1 (0.51h) but a decrease during month 2 (-0.74 h; contrast=-1.24, CI =-2.06, -0.42, p =0.005). No other significant effects were observed., Conclusions: SPP is highly feasible, acceptable, and associated with a significant increase in TST early in treatment., Clinical Trial Registration: Registry: ClinicalTrials.gov; Name: Targeted Intervention for Insufficient Sleep among Typically-Developing Adolescents; Identifier: NCT04163003; URL: https://clinicaltrials.gov/ct2/show/NCT04163003., (© 2024 American Academy of Sleep Medicine.)

Introduction: Suicidal thoughts and behaviors often onset during adolescence, constituting a major public health concern. Despite rising rates in youth, psychotherapeutic and pharmacological treatment outcomes remain meager, indicating a need to identify modifiable risk factors. Experts suggest sleep may serve as a promising clinical indicator of risk and treatment progress, yet few studies have examined acute temporal associations between sleep and suicidal ideation., Methods: Participants were depressed and suicidal adolescents (age 13-19, n = 311) attending an intensive outpatient program (IOP). Patients completed weekly self-report assessments of sleep, depression, and suicidal ideation throughout IOP, with an average of 5 assessments over 30 days., Results: Greater overall sleep difficulties, as well as within-person increases in sleep difficulties, were predictive of greater depression severity and suicidal ideation at subsequent assessments, above and beyond previous levels of symptoms. The reverse associations were not found. Inclusion of within-person changes in sleep difficulties significantly improved model fit compared to inclusion of overall sleep difficulties alone., Discussion: This study provides additional evidence for a prospective relationship between worsening sleep difficulties and suicidal ideation in an IOP youth sample. Worsening sleep may be an important clinical indicator of subsequent depression and suicide risk among adolescents in treatment., (© 2024 The Author(s).

Background: Previous studies demonstrate a link between irritability and suicidal thoughts and behaviors (STBs) in youth samples. However, they have mostly assessed irritability in community samples and as a largely dispositional (i.e. trait-like) construct. Thus, it remains unclear to what extent links between irritability and STBs reflect within-person processes of elevated risk in clinically meaningful time periods., Methods: The present study used clinical data from 689 adolescents aged 12-19 years attending a total of 6,128 visits at a specialty Intensive Outpatient Program for depressed and suicidal youth to examine patterns in weekly assessments of irritability and STBs throughout treatment, including associations among trends and fluctuations departing from these trends via multilevel structural equation modeling. Youth completed self-report measures of irritability, depression, and STBs weekly as part of standard IOP clinical care., Results: Overall, two-thirds of variance in weekly irritable mood was accounted for by between-person differences and the remaining portion by weekly fluctuations. After controlling for depression, during weeks when youth were more irritable they experienced increased STBs. Rates of change in irritability and STBs tended to track together at early stages of treatment, but these effects were generally accounted for by depression severity., Conclusions: Our results suggest that although changes in STBs are best accounted for by depression, irritability can be understood as a specific, proximal risk factor for youth STBs that exacerbates youth STBs in clinically informative timeframes above and beyond depression., (© 2024 The Authors.

Background: Previous work indicates that polygenic risk scores (PRS) for bipolar disorder (BD) are elevated in adults and youth with BD, but whether BD-PRS can inform person-level diagnostic prediction is unknown. Here, we test whether BD-PRS improves performance of a previously published risk calculator (RC) for BD., Methods: 156 parents with BD-I/II and their offspring ages 6-18 were recruited and evaluated with standardized diagnostic assessments every two years for >12 years. DNA was extracted from saliva samples, genotyping performed, and BD-PRS calculated based on a 2021 meta-analysis. Using a bootstrapped and cross-validated penalized Cox regression, we assessed whether BD-PRS (alone and interacting with clinical variables) improved RC performance., Results: Of 227 offspring, 38 developed BD during follow-up. The penalized regression selected BD-PRS and interactions between BD-PRS and parental age at mood disorder onset (AAO), depression, and anxiety. The resulting RC discriminated offspring who developed BD (vs. those that did not) with good accuracy (AUC = 0.81); removing BD-PRS and its interaction terms was associated with a significant decrement to the AUC (decrement = 0.07, p = 0.039). Further exploration of selected interaction terms indicated that all were significant (p-values<0.02), indicating that BD-PRS has a larger effect on the outcome in offspring with depression and anxiety, whose affected parent had a younger AAO., Conclusions: The addition of BD-PRS to clinical/demographic predictors in the RC significantly improved its accuracy. BD-PRS predicted BD on the person-level, particularly in offspring of parents with earlier AAO who already had symptoms of anxiety and depression at intake., Competing Interests: Declaration of competing interest Dr. Hafeman reports grants from NIMH and the Brain and Behavior Research Foundation.

Background: Poor sleep is prevalent in adolescents with bipolar disorder, precedes illness onset, and is associated with worse mood symptoms. We examined interrelationships between sleep quality and mood symptoms in adolescents with bipolar disorder, particularly effects of sleep quality on emergent mood symptoms., Methods: Adolescents with bipolar disorder participated in a two-year longitudinal treatment study. Sleep quality (Pittsburgh Sleep Quality Index, PSQI) was assessed quarterly during treatment (baseline, 3-, 6-, 9-, 12-month visits) and twice during follow-up (18-, 24-month visits). Mood symptoms (ALIFE Psychiatric Status Ratings) were retrospectively rated weekly by an independent clinician. Lag models tested whether sleep quality predicted next month's mood symptoms and whether mood symptoms predicted future sleep quality., Results: Adolescents with bipolar disorder had poor sleep quality. Sleep quality initially improved but remained stable thereafter. Worse sleep quality at 6-months predicted worse depression, hypomania, and suicidal ideation the following month. Sleep quality was worse for adolescents who had a suicide attempt during the study compared to those who did not and was worse preceding months with a suicide attempt compared to months without attempts. Alternatively, worse depression predicted worse future sleep quality at baseline, 3-, and 18-months and worse suicidal ideation predicted worse future sleep quality at baseline, 12-, and 18-months., Limitations: Mood symptoms were rated retrospectively and the PSQI may not capture all dimensions of sleep important for mood symptoms., Conclusions: Targeted evidence-based sleep treatment in adolescents with bipolar disorder may alleviate sleep problems and have additional benefits on mood symptoms and suicidality risk., Competing Interests: Declaration of competing interest The authors declare that they have no conflicts of interest to disclose., (Copyright © 2024 The Authors.

Objective: We present results from a 2-site, randomized clinical trial to assess the efficacy of a brief intervention (As Safe As Possible [ASAP]), a safety plan phone application (BRITE), and their combination on suicide attempts, suicidal ideation, non-suicidal self-injury, re-hospitalizations. and suicidal events among adolescents., Method: Adolescents (n= 240; 12-17 years of age) who were hospitalized for suicidal ideation with plan and/or intent, and/or suicide attempt, were assigned to 1 of 4 treatment conditions in a 2 by 2 design: ASAP+BRITE app+treatment as usual (TAU); (2) BRITE+TAU; (3) ASAP+TAU; and (4) TAU alone. Independent evaluators assessed suicidal ideation and behavior at 4, 12, and 24 weeks using the Columbia-Suicide Severity Rating Scale (C-SSRS) and re-hospitalization using the Child and Adolescent Services Assessment (CASA)., Results: No group differences were found on primary outcomes, except that ASAP participants were less likely to be re-hospitalized over 6 months (15.6%, vs 26.5%, p = .046). Participants hospitalized for an attempt and assigned to BRITE had a lower rate of subsequent attempts (odds ratio [OR] = 0.16, p = .01) and a greater time to attempt (hazard ratio [HR] = 0.20, p = .02). ASAP+BRITE, albeit not statistically significant, was most consistently associated with a reduction (60% reduction) in suicide attempts., Conclusion: ASAP, BRITE, and their combination are equally effective at decreasing risk for suicidal events 6 months post hospital discharge among suicidal adolescents; the ASAP intervention (with or without BRITE) was associated with lower rates of re-hospitalization. The BRITE app in youth hospitalized for suicide attempt had promising outcomes in regard to future attempts., Diversity & Inclusion Statement: We worked to ensure sex and gender balance in the recruitment of human participants.

Objectives: Bipolar disorder (BD) is highly heritable and associated with increased rates of metabolic syndrome (MetS). However, little is known about MetS in offspring of parents with BD. We therefore examined this topic in the Pittsburgh Bipolar Offspring Study cohort., Methods: Participants included 199 parents (n = 116 BD, diagnosed using DSM-IV ; n = 83 non-BD) and 330 offspring (mean age 19.9 ± 5.3 years), including 198 high-risk offspring of parents with BD (n = 80 affected with a mood disorder) and 132 control offspring. We defined MetS and its components using International Diabetes Federation (IDF) guidelines (primary) and National Cholesterol Education Program (NCEP) guidelines (secondary). Multivariable analyses controlled for age and socioeconomic status in offspring. Sensitivity analyses controlled for psychotropic medications., Results: There was higher prevalence of MetS in parents with BD as compared to controls. NCEP-defined MetS was significantly more prevalent among affected high-risk offspring (16.3%) and controls (15.2%) vs unaffected high-risk offspring (6.0%; χ 2 = 6.54, P = .04). There was greater mean number of MetS components (IDF: 1.7 ± 1.1; NCEP: 1.4 ± 1.0) among affected high-risk offspring vs unaffected high-risk offspring (IDF: 1.2 ± 1.0; NCEP: 1.0 ± 1.0) and controls (IDF: 1.3 ± 1.2; NCEP: 1.1 ± 1.1; IDF: H [2] = 10.26, P = .006; NCEP: H [2] = 9.18, P = .01). Most findings became nonsignificant in multivariable analyses. Some between-group results became nonsignificant after controlling for second-generation antipsychotics., Conclusions: This preliminary study found increased risk of MetS among affected high-risk offspring, which may be attributable to socioeconomic status. Prospective studies may determine timing of MetS onset in relation to mood disorder onset, and the role of socioeconomic status in moderating this association., (© Copyright 2024 Physicians Postgraduate Press, Inc.)

Background: Bipolar disorder (BD) conveys the highest risk of suicide of all mental disorders. We sought to externally validate a risk calculator (RC) of suicide attempts developed in youth with BD from the Course and Outcome of Bipolar Youth (COBY) study in an adult sample., Methods: A prospective cohort of adults with BD from the National Institute of Mental Health Collaborative Depression Study (CDS; N = 427; mean (+/- SD) age at intake (36 +/- 13 years)) was secondarily analyzed to validate the COBY RC for one-year risk of suicide attempts/deaths. Nine of the ten predictor variables from the COBY RC were available in the CDS and used: age, age of mood disorder onset, first and second (partial) degree family history of suicide, history of psychotic symptoms, substance use disorder, prior suicide attempt, socioeconomic status, and non-suicidal self-injury (prospectively, incompletely at baseline)., Results: Over a mean (SD) follow-up of 19 (10) years, 29 % of the CDS sample attempted suicide. The RC predicted suicide attempts/deaths over one-year follow-up with an area under the receiver operating characteristic curve (AUC) of 0.78 (95 % CI 0.75-0.80). The RC performed slightly better in those with a younger age of mood disorder onset., Limitations: Clinical samples may limit generalizability; the RC does not assess more acute suicide risk., Conclusions: One-year risk of suicide attempts/deaths can be predicted with acceptable accuracy in youth and adults with BD, comparable to commonly used RCs to predict cardiovascular risk. This RC may help identify higher-risk individuals with BD for personalized treatment and research. https://cobysuicideattemptsrc.shinyapps.io/Shiny., Competing Interests: Declaration of competing interest Dr. Fiedorowicz has received research support from the National Institute of Mental Health (NIMH) and National Center for Advancing Translational Sciences (NCATS).

Study Objectives: Healthy sleep is important for adolescent neurodevelopment, and relationships between brain structure and sleep can vary in strength over this maturational window. Although cortical gyrification is increasingly considered a useful index for understanding cognitive and emotional outcomes in adolescence, and sleep is also a strong predictor of such outcomes, we know relatively little about associations between cortical gyrification and sleep. We aimed to identify developmentally invariant (stable across age) or developmentally specific (observed only during discrete age intervals) gyrification-sleep relationships in young people., Methods: A total of 252 Neuroimaging and Pediatric Sleep Databank participants (9-26 years; 58.3% female) completed wrist actigraphy and a structural MRI scan. Local gyrification index (lGI) was estimated for 34 bilateral brain regions. Naturalistic sleep characteristics (duration, timing, continuity, and regularity) were estimated from wrist actigraphy. Regularized regression for feature selection was used to examine gyrification-sleep relationships., Results: For most brain regions, greater lGI was associated with longer sleep duration, earlier sleep timing, lower variability in sleep regularity, and shorter time awake after sleep onset. lGI in frontoparietal network regions showed associations with sleep patterns that were stable across age. However, in default mode network regions, lGI was only associated with sleep patterns from late childhood through early-to-mid adolescence, a period of vulnerability for mental health disorders., Conclusions: We detected both developmentally invariant and developmentally specific ties between local gyrification and naturalistic sleep patterns. Default mode network regions may be particularly susceptible to interventions promoting more optimal sleep during childhood and adolescence., (© The Author(s) 2023.

Importance: Early-onset bipolar disorder conveys substantial risk for suicide. No psychosocial intervention for this population expressly targets suicidal behavior., Objective: To determine whether dialectical behavior therapy (DBT) for adolescents with bipolar spectrum disorder is more effective than standard of care (SOC) psychotherapy in decreasing suicide attempts over 1 year., Design, Settings, and Participants: Adolescents aged 12 to 18 years diagnosed with bipolar spectrum disorder were recruited from a specialty outpatient psychiatric clinic between November 2014 and September 2019. Independent evaluators conducted quarterly assessments over 1 year with participants and parents. Data were analyzed from March 2021 to November 2022., Interventions: Participants were randomly assigned to 1 year of DBT (36 sessions; n = 47) or SOC psychotherapy (schedule clinically determined; n = 53). All youth received medication management via a flexible algorithm., Main Outcomes and Measures: Primary outcomes included suicide attempts over 1 year and mood symptoms and states (depression and hypomania/mania). Secondary analyses included moderation of DBT effects by history of suicide attempt and mediation through emotion dysregulation., Results: Of 100 included participants, 85 (85%) were female, and the mean (SD) age was 16.1 (1.6) years. Participants were followed up over a mean (SD) of 47 (14) weeks. Both treatment groups demonstrated significant and similar improvement in mood symptoms and episodes over 1 year (standardized depression rating scale slope, -0.17; 95% CI, -0.31 to -0.03; standardized mania rating scale slope, -0.24; 95% CI, -0.34 to -0.14). DBT and SOC participants reported similar suicide attempt rates at intake as measured on the Adolescent Longitudinal Follow-Up Evaluation (ALIFE; mean [SD] attempts, 2.0 [4.5] vs 1.8 [3.9], respectively; P = .80). DBT participants reported slightly more suicide attempts at intake as measured on the Columbia-Suicide Severity Rating Scale Pediatric Version (C-SSRS; mean [SD] attempts, 1.4 [3.6] vs 0.6 [0.9]; P = .02). DBT participants reported significantly fewer suicide attempts over follow-up compared with SOC participants via the ALIFE (mean [SD] attempts per follow-up period, 0.2 [0.4] vs 1.1 [4.3], controlling for baseline attempts: P = .03) and the C-SSRS (mean [SD] attempts per follow-up period, 0.04 [0.2] vs 0.10 [0.3], controlling for baseline attempts; P = .03). DBT was significantly more effective than SOC psychotherapy at decreasing suicide attempts over 1 year (ALIFE: incidence rate ratio [IRR], 0.32; 95% CI, 0.11-0.96; C-SSRS: IRR, 0.13; 95% CI, 0.02-0.78). Decreased rate of suicide attempts in DBT was moderated by presence of lifetime history of suicide attempt and time (IRR, 0.23; 95% CI, 0.13-0.44) and mediated by improvement in emotion dysregulation (IRR, 0.61; 95% CI, 0.42-0.89), particularly for those with high baseline emotion dysregulation (standardized β, -0.59; 95% CI, -0.92 to -0.26)., Conclusions and Relevance: In this randomized clinical trial, DBT demonstrated efficacy in decreasing suicide attempts among the high-risk population of adolescents with bipolar spectrum disorder., Trial Registration: ClinicalTrials.gov Identifier: NCT02003690.

Two studies examined the process and aftermath of coming to disbelieve in the myth of Santa Claus. In Study 1, 48 children ages 6-15 answered questions about how they discovered Santa was not real and how the discovery made them feel, and 44 of their parents shared their perspectives and how they promoted Santa. In Study 2, 383 adults reflected on their experiences shifting to disbelief in Santa Claus. In both studies, the average age of disbelief was around 8, but with significant variability. Most participants reported testimony from others contributed to their disbelief, and some reported skepticism as a result of either experience (e.g., observation) or logical reasoning. About a third of children and half of adults reported some negative emotions upon discovering the truth. Higher levels of parental Santa promotion were associated with experiencing some negative emotions upon discovering the truth in both studies. Additionally, adults who reported feeling only negative emotions tended to be older when they discovered the truth, more likely to have reported learning the truth abruptly, and more likely to have reported learning the truth through testimony. That said, experiences of negative emotions were generally short-lived, and the vast majority of both children and adults reported they would celebrate Santa with their own children or were already doing so. Implications of these findings for how to approach children's transition to skepticism regarding Santa are discussed, including timing, the role of parents, and popular notions of discovery for children's trust toward their parents.

Objectives: To build a one-year risk calculator (RC) to predict individualized risk for suicide attempt in early-onset bipolar disorder., Methods: Youth numbering 394 with bipolar disorder who completed ≥2 follow-up assessments (median follow-up length = 13.1 years) in the longitudinal Course and Outcome of Bipolar Youth (COBY) study were included. Suicide attempt over follow-up was assessed via the A-LIFE Self-Injurious/Suicidal Behavior scale. Predictors from the literature on suicidal behavior in bipolar disorder that are readily assessed in clinical practice were selected and trichotomized as appropriate (presence past 6 months/lifetime history only/no lifetime history). The RC was trained via boosted multinomial classification trees; predictions were calibrated via Platt scaling. Half of the sample was used to train, and the other half to independently test the RC., Results: There were 249 suicide attempts among 106 individuals. Ten predictors accounted for >90% of the cross-validated relative influence in the model (AUC = 0.82; in order of relative influence): (1) age of mood disorder onset; (2) non-suicidal self-injurious behavior (trichotomized); (3) current age; (4) psychosis (trichotomized); (5) socioeconomic status; (6) most severe depressive symptoms in past 6 months (trichotomized none/subthreshold/threshold); (7) history of suicide attempt (trichotomized); (8) family history of suicidal behavior; (9) substance use disorder (trichotomized); (10) lifetime history of physical/sexual abuse. For all trichotomized variables, presence in the past 6 months reliably predicted higher risk than lifetime history., Conclusions: This RC holds promise as a clinical and research tool for prospective identification of individualized high-risk periods for suicide attempt in early-onset bipolar disorder.Reprinted from Bipolar Disord 2022; 24:749-757 , with permission from John Wiley and Sons.

Background: Offspring of parents with bipolar disorder (BD-I/II) are at increased risk to develop the disorder. Previous work indicates that bipolar spectrum disorder (BPSD) is often preceded by mood/anxiety symptoms. In school-age offspring of parents with BD, we previously built a risk calculator to predict BPSD onset, which generates person-level risk scores. Here, we test whether preschool symptoms predict school-age BPSD risk., Methods: We assessed 113 offspring of parents with BD 1-3 times during preschool years (2-5 years old) and then approximately every 2 years for a mean of 10.6 years. We used penalized (lasso) regression with linear mixed models to assess relationships between preschool mood, anxiety, and behavioral symptoms (parent-reported) and school-age predictors of BPSD onset (i.e., risk score, subthreshold manic symptoms, and mood lability), adjusting for demographics and parental symptomatology. Finally, we conducted survival analyses to assess associations between preschool symptoms and school-age onset of BPSD and mood disorder., Results: Of 113 preschool offspring, 33 developed new-onset mood disorder, including 19 with new-onset BPSD. Preschool irritability, sleep problems, and parental factors were lasso-selected predictors of school-age risk scores. After accounting for demographic and parental factors, preschool symptoms were no longer significant. Lasso regressions to predict mood lability and subthreshold manic symptoms yielded similar predictors (irritability, sleep problems, and parental affective lability), but preschool symptoms remained predictive even after adjusting for parental factors (ps < .005). Exploratory analyses indicated that preschool irritability univariately predicted new-onset BPSD (p = .02) and mood disorder (p = .02)., Conclusions: These results provide initial prospective evidence that, as early as preschool, youth who will develop elevated risk scores, mood lability, and subthreshold manic symptoms are already showing symptomatology; these preschool symptoms also predict new-onset BPSD. While replication of findings in larger samples is warranted, results point to the need for earlier assessment of risk and development of early interventions., (© 2022 Association for Child and Adolescent Mental Health.)

Objective: To assess medication adherence and factors associated with poor adherence in youth with bipolar disorder (BD) followed from adolescence through young adulthood., Method: Participants with BD recruited through the Course and Outcome of Bipolar Youth (COBY) study were included in this study if they were prescribed psychotropic medications and had at least 3 follow-up assessments of medication adherence (N= 179, ages 12-36). Medication adherence had been evaluated for a median of 8 years using a questionnaire derived from the Coronary Artery Risk Development in Young Adults (CARDIA) study. For the longitudinal evaluation, adherence was measured as the percentage of follow-up assessments in which the participants did not endorse any of the nonadherence items included in the questionnaire. Concurrent and future predictors of poor adherence were assessed using both univariate and multivariate longitudinal analyses., Results: Among the participants, 51% reported poor adherence in more than 50% of their follow-up assessments. Younger age, family conflicts, polypharmacy, lower functioning, greater severity of mood symptoms, and comorbid disorders were associated with poor adherence in the univariate analyses. In the multivariate analyses, comorbid ADHD was the single most influential factor associated with concurrent and future poor adherence in all age groups. Participants' most reported reasons for poor adherence were forgetfulness (56%), negative attitudes toward medication treatment (10.5%), and disturbed daily routine (7%)., Conclusions: Poor medication adherence is a significant problem in youth with BD with the most influential factor being the presence of comorbid ADHD. Thus, it is important to identify and appropriately treat comorbid ADHD to improve medication adherence and patients' prognosis. Providers should also recommend tools to enhance consistent medication intake and address patients' concerns and negative beliefs about their illness and treatment.

Measurement-based care has demonstrable benefits, but significant implementation barriers slow dissemination in real-world clinical settings, especially youth behavioral health care. Here, we describe use of measurement-based care in a specialty clinic offering a continuum of outpatient care for suicidal youth. We characterize strategies used to facilitate measurement-based care in this population and ways in which challenges to implementation have been addressed. We examined adherence to measurement-based care procedures relative to treatment engagement data from electronic medical records, as well as data from clinicians regarding acceptability and utility of measurement-based care. Results suggest that measurement-based care is both feasible and acceptable for use with suicidal youth. Here we provide future directions in measurement-based care in this, and other, behavioral health settings., Competing Interests: We have read the journal’s policy and the authors of this manuscript have the following competing interests: Dr. Brent receives research support from the National Institutes of Health, American Foundation for Suicide Prevention, the Once Upon a Time Foundation, and The Beckwith Foundation; receives royalties from Guilford Press, from the electronic self-rated version of the C-SSRS from eRT, Inc., and from performing duties as an UptoDate Psychiatry Section Editor; receives consulting fees from Healthwise; receives Honoraria from the Klingenstein Third Generation Foundation for scientific board membership and grant reviews; and is a scientific board member for the American Foundation for Suicide Prevention.

Objective: College counseling centers (CCCs) have limited capacity to accommodate high-risk students who need more intensive care than traditional outpatient treatment. We describe an Intensive Outpatient Program (IOP) to meet the specialized needs of suicidal undergraduates. Participants: Suicidal undergraduates aged 18-24. Methods: Fact-gathering meetings with local universities confirmed high need for prompt access to IOP care for students presenting in crisis at CCCs and emergency rooms, and post-inpatient discharge. We thus iteratively designed and implemented the College Option Services for Teens at Risk (COSTAR) IOP. Results: The 6-week program includes initial diagnostic evaluation and risk assessment followed by weekly skills groups, individual therapy, and medication management. Between September 2017 and January 2020, 148 students ( M age = 19.7) attended an average of 5.7 COSTAR group sessions ( SD  = 4.7). Conclusions: A specialty IOP for suicidal college students holds promise in a stepped care approach for at-risk college students.

Purpose: We examined whether interindividual differences in naturalistic sleep patterns correlate with any deviations from typical brain aging., Methods: Our sample consisted of 251 participants without current psychiatric diagnoses (9-25 years; mean [standard deviation] = 17.4 ± 4.52 yr; 58% female) drawn from the Neuroimaging and Pediatric Sleep Databank. Participants completed a T1-weighted structural magnetic resonance imaging scan and 5-7 days of wrist actigraphy to assess naturalistic sleep patterns (duration, timing, continuity, and regularity). We estimated brain age from extracted structural magnetic resonance imaging indices and calculated brain age gap (estimated brain age-chronological age). Robust regressions tested cross-sectional associations between brain age gap and sleep patterns. Exploratory models investigated moderating effects of age and biological gender and, in a subset of the sample, links between sleep, brain age gap, and depression severity (Patient-Reported Outcomes Measurement Information System Depression)., Results: Later sleep timing (midsleep) was associated with more advanced brain aging (larger brain age gap), β = 0.1575, p uncorr  = .0042, p fdr  = .0167. Exploratory models suggested that this effect may be driven by males, although the interaction of gender and brain age gap did not survive multiple comparison correction (β = 0.2459, p uncorr  = .0336, p fdr  = .1061). Sleep duration, continuity, and regularity were not significantly associated with brain age gap. Age did not moderate any brain age gap-sleep relationships. In this psychiatrically healthy sample, depression severity was also not associated with brain age gap or sleep., Discussion: Later midsleep may be one behavioral cause or correlate of more advanced brain aging, particularly among males. Future studies should examine whether advanced brain aging and individual differences in sleep precede the onset of suboptimal cognitive-emotional outcomes in adolescents., (Copyright © 2022 Society for Adolescent Health and Medicine.

Background: Identifying proximal risk factors for suicidal ideation that are modifiable and relevant for adolescents and young adults is critical for suicide prevention. This study used an intensive monitoring approach to examine whether objectively- and subjectively- measured sleep characteristics predict next-day suicidal ideation occurrence and intensity through affective reactivity to interpersonal events in young people at high risk for suicide., Methods: Participants included 59 (13-23 years; 76% White; 75% female) adolescents and young adults undergoing intensive outpatient program treatment for depression and suicidality. Participants completed daily ratings of suicidal ideation, sleep quality, and affective reactivity to positive and negative interpersonal events for up to 3 months (M = 56 days, SD = 24.13). Actigraphy captured behavioral sleep duration and timing. Multilevel modeling was used to evaluate within-person fluctuations in sleep and affective reactivity as predictors of suicidal ideation, and multilevel mediation tested the indirect effects of sleep on suicidal ideation via affective reactivity to interpersonal events., Results: Results indicate significant indirect effects of objectively measured sleep duration and subjective sleep quality on next-day suicidal ideation via affective reactivity to negative and positive interpersonal events, respectively. Shorter-than-usual sleep predicted the presence and intensity of next-day suicidal ideation via heightened affective reactivity to negative interpersonal events. Worse sleep quality than usual predicted next-day suicidal ideation via reduced affective reactivity to positive interpersonal events., Conclusions: Affectivity reactivity is a proximal mechanism through which sleep indices may influence risk for suicidal thinking on a daily basis. Findings highlight the utility of targeting sleep and emotion regulation in suicide prevention among adolescents and young adults at high-risk for suicide., (© 2022 The Authors.

While Dubourg and Baumard argue that predisposition toward exploration draws us to fictional environments, they fail to answer their titular question: "Why Imaginary Worlds?" Research in pretend play, psychological distancing, and theatre shows that being "imaginary" (i.e., any type of unreal, rather than only fantastically unreal) makes exploration of any fictional world profoundly different than that of real-life unfamiliar environments.

Objectives: To build a one-year risk calculator (RC) to predict individualized risk for suicide attempt in early-onset bipolar disorder., Methods: Youth numbering 394 with bipolar disorder who completed ≥2 follow-up assessments (median follow-up length = 13.1 years) in the longitudinal Course and Outcome of Bipolar Youth (COBY) study were included. Suicide attempt over follow-up was assessed via the A-LIFE Self-Injurious/Suicidal Behavior scale. Predictors from the literature on suicidal behavior in bipolar disorder that are readily assessed in clinical practice were selected and trichotomized as appropriate (presence past 6 months/lifetime history only/no lifetime history). The RC was trained via boosted multinomial classification trees; predictions were calibrated via Platt scaling. Half of the sample was used to train, and the other half to independently test the RC., Results: There were 249 suicide attempts among 106 individuals. Ten predictors accounted for >90% of the cross-validated relative influence in the model (AUC = 0.82; in order of relative influence): (1) age of mood disorder onset; (2) non-suicidal self-injurious behavior (trichotomized); (3) current age; (4) psychosis (trichotomized); (5) socioeconomic status; (6) most severe depressive symptoms in past 6 months (trichotomized none/subthreshold/threshold); (7) history of suicide attempt (trichotomized); (8) family history of suicidal behavior; (9) substance use disorder (trichotomized); (10) lifetime history of physical/sexual abuse. For all trichotomized variables, presence in the past 6 months reliably predicted higher risk than lifetime history., Conclusions: This RC holds promise as a clinical and research tool for prospective identification of individualized high-risk periods for suicide attempt in early-onset bipolar disorder., (© 2022 John Wiley & Sons A/S.

Objective: Early-onset bipolar disorder is among the costliest psychiatric disorders; yet inpatient and outpatient service use patterns in this group are largely unknown. One-year behavioral and medical health service use was examined among adolescents diagnosed as having bipolar disorder, and rates were compared between adolescents with threshold versus subthreshold bipolar disorder., Methods: Participants included 100 adolescents (ages 12–18 years, 85% had been assigned female sex at birth) diagnosed as having bipolar disorder (type I, N=14; type II, N=28; not otherwise specified [NOS], N=58) via semistructured interviews and who consented to electronic health record (EHR) data review for enrollment in a psychosocial treatment study. Service use data were extracted in the year preceding study entry from a data repository containing all clinical and financial records (including outpatient and inpatient behavioral and medical visits) from a large western Pennsylvania health system., Results: EHRs indicated that 99% of adolescents used some behavioral health service, most commonly outpatient psychotherapy (60%) and medication management (43%). Use of intensive behavioral health services was common (49%), and 48% had at least one psychotropic medication noted in their EHR. General medical health services were used by 78%, most commonly outpatient (67%) and emergency department (39%) visits. No differences in service use were observed for adolescents with bipolar disorder type I or II compared with NOS for any services or medications examined., Conclusions: High use of behavioral and medical health services among adolescents with bipolar spectrum disorders has important implications for health care systems, insurers, providers, and consumers. Greater coordination of health care for this high-risk, high-use population may improve outcomes.

Despite a plethora of research, the link between digital technology use and psychological distress among young adults remains inconclusive. Findings in this area are typically undermined by methodological limitations related to measurement, study design, and statistical analysis. Addressing these limitations, we examined the prospective, within-person associations between three aspects of objectively-measured digital technology use (smartphone use duration and frequency; social media use duration) and three aspects of psychological distress (depression, anxiety, and social isolation) among a sample of young adults ( N = 384). Across 81 different model specifications, we found that most within-person prospective effects between digital technology use and psychological distress were statistically non-significant and all were very small-even the largest effects were unlikely to register a meaningful impact on a person's psychological distress. In post hoc subgroup analyses, we found scant evidence for the claim that digital technology use is more harmful for women and/or younger people.

Objective: Sleep changes over the human life span, and it does so across multiple dimensions. We used individual-level cross-sectional data to characterize age trends and sex differences in actigraphy and self-report sleep dimensions across the healthy human life span., Methods: The Pittsburgh Lifespan Sleep Databank consists of harmonized participant-level data from sleep-related studies conducted at the University of Pittsburgh (2003-2019). We included data from 1065 (n = 577 female; 21 studies) Pittsburgh Lifespan Sleep Databank participants aged 10 to 87 years without a major psychiatric, sleep, or medical condition. All participants completed wrist actigraphy and the self-rated Pittsburgh Sleep Quality Index. Main outcomes included actigraphy and self-report sleep duration, efficiency, and onset/offset timing, and actigraphy variability in midsleep timing., Results: We used generalized additive models to examine potentially nonlinear relationships between age and sleep characteristics and to examine sex differences. Actigraphy and self-report sleep onset time shifted later between ages 10 and 18 years (23:03-24:10 [actigraphy]; 21:58-23:53 [self-report]) and then earlier during the 20s (00:08-23:40 [actigraphy]; 23:50-23:34 [self-report]). Actigraphy and self-report wake-up time also shifted earlier during the mid-20s through late 30s (07:48-06:52 [actigraphy]; 07:40-06:41 [self-report]). Self-report, but not actigraphy, sleep duration declined between ages 10 and 20 years (09:09-07:35). Self-report sleep efficiency decreased over the entire life span (96.12-93.28), as did actigraphy variability (01:54-01:31)., Conclusions: Awareness of age trends in multiple sleep dimensions in healthy individuals-and explicating the timing and nature of sex differences in age-related change-can suggest periods of sleep-related risk or resilience and guide intervention efforts., (Copyright © 2022 by the American Psychosomatic Society.)

Background: To identify prospectively ascertained individual and family factors that are associated with improvement in Bipolar Disorder (BD) among youths who initially presented with poor course., Methods: 82 youths with BD with persistent poor mood symptomatology ("predominantly ill course") were compared to 70 youths with BD who at intake had poor course, but showed improvement during the follow-up ("ill with improving course"), (ages 12.3 ± 3.3, vs. 11.7 ± 3.3 years old, at intake). Improvement was measured by the percentage of time euthymic during a mean follow-up of 12.8 years. Youths and parents were interviewed to assess psychopathology, functioning, treatment, and familial functioning and psychopathology., Results: Compared to the ill group, since intake, the improving group showed significantly lower subthreshold depression and hypo/mania, Attention Deficit Hyperactivity Disorder, and Disruptive Behavior Disorders. Parental Socioeconomic Status (SES) remained unchanged over time in the ill group, but progressively increased in the improving group. Importantly, the change in SES predated the improvement in the mood trajectory. The most influential variables that predicted improvement were higher SES, and absence of parental BD and Substance Use Disorder (SUD). Parental SUD also negatively affected the parental SES, which was directly associated with worse mood course., Limitations: Predominantly self-reported White samples may limit generalizability; other factors potentially associated with outcome (e.g., treatment adherence), were not ascertained., Conclusions: In addition to treating mood/comorbid psychopathology in symptomatic BD youths, to improve their prognosis, it is crucial to address their parent's BD and SUD and promote parental education/employment., (Copyright © 2022.

Objective This study investigated binge drinking in college students with and without disabilities and sexual violence (SV). Participants: This analysis includes 2,113 college students recruited from campus health or counseling centers between 2015 and 2017, aged 18-24. Method: Multinomial logistic regression procedures were used to estimate adjusted odds ratios (AOR) for past month binge drinking days (BDD). Results: Among students with disabilities, 68% endorsed SV, compared with 53% of those without disability. Disability was not significantly associated with BDD; SV was significantly associated with BDD ( p < .0001). Students with SV, regardless of disability status, had 1.7- to 2.1-fold greater odds of having 4+ past month BDD. Conclusions: While disability alone is not a risk factor for binge drinking, novel findings include that students with disabilities binge drink at similarly high rates to their nondisabled peers, and are at elevated risk for SV, which is closely associated with binge drinking.

Purpose of Review: Suicide is currently the second leading cause of death among youth. Identification of modifiable near-term risk factors can inform suicide prevention strategies. One promising, readily assessed factor is sleep. We critically review the literature on sleep and suicidal thoughts and behaviors among youth., Recent Findings: Most studies examining the youth sleep-suicidality relationship are from epidemiological samples in which both sleep problems and suicidality were assessed over variable timeframes using limited items from scales not designed to measure these constructs. Nonetheless, these data overwhelmingly support an association between suicidality and a range of sleep difficulties (e.g., insomnia, short/long sleep, weekend oversleep), above and beyond depressive symptoms. Limited studies include clinical samples or prospective designs. We review potential mechanisms and present a developmentally-informed integrative model., Summary: Literature supports a clear association between sleep difficulties and youth suicidality. Future directions include prospective longitudinal studies and targeted prevention efforts.

Background: Childhood abuse negatively impacts the course of Bipolar Disorder (BD). Yet, no study has examined risk factors associated with prospectively evaluated physical/sexual abuse, specifically, those preceding first abuse among BD youth. We investigate past/intake/follow-up factors preceding first physical/sexual abuse among BD youth., Methods: Childhood-onset BD participants (n = 279 youth, mean age at intake = 12, mean length of follow-up = 12 years) enrolled in the Course and Outcome of Bipolar Youth (COBY) study. Demographic, clinical and family history variables were assessed every 7 months on average using Longitudinal Interval Follow-up Evaluation and Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL). Abuse was evaluated at intake using the K-SADS-PL, over follow-up with a Traumatic Events Screen. Family psychopathology was assessed using Family History Screen/Structured Clinical Interview for Diagnostic Statistical Manual-IV., Results: Fifteen-percent of youth reported new-onset abuse during follow-up (62% physical, 26% sexual; 12% both). Intake predictors included more severe depressive symptoms (HR = 1.29), low socioeconomic-status (SES) in families with substance abuse (HR = 0.84) (physical abuse), and female sex (HR = 2.41) (sexual abuse). Follow-up predictors preceding physical abuse included: older age (HR = 1.42), disruptive disorders (HR = 1.39), and the interaction between low SES and family substance abuse (HR = 0.86). For sexual abuse, female sex (HR = 4.33) and a non-biologically related father presence in the household (HR = 2.76). Good relationships with friends (prospectively evaluated) protected against physical/sexual abuse (HR = 0.72/0.70, respectively)., Limitations: Prospective data was gathered longitudinally but assessed retrospectively at every follow-up; perpetrator information and abuse severity were not available., Conclusions: Identifying factors temporally preceding new onset physical/sexual abuse may hold promise for identifying high-risk youth with BD., (Copyright © 2022 Elsevier B.V.

Imaginative pretend play is often thought of as the domain of young children, yet adults regularly engage in elaborated, fantastical, social-mediated pretend play. We describe imaginative play in adults via the term "pretensive shared reality;" Shared Pretensive Reality describes the ability of a group of individuals to employ a range of higher-order cognitive functions to explicitly and implicitly share representations of a bounded fictional reality in predictable and coherent ways, such that this constructed reality may be explored and invented/embellished with shared intentionality in an ad hoc manner. Pretensive Shared Reality facilitates multiple individual and social outcomes, including generating personal and group-level enjoyment or mirth, the creation or maintenance of social groups, or the safe exploration of individual self-concepts (such as alternative expression of a players sexual or gender identity). Importantly, Pretensive Shared Reality (both within the specific context of table-top role-playing games, and other instances) are primarily co-operative and co-creative. We draw on multiple examples, and focus on Table-Top Role Playing games (TTRPG) - and specifically, the most popular and enduring table-top role-playing games, Dungeons & Dragons (D&D) - as a primary example of such play. Our conception of "pretensive shared reality" links the widespread existence and forms of adult imaginative play to childhood pretense, places it within a developmental and evolutionary context, and argues that pretensive shared realities - which underpin many forms of imaginative culture - are an important topic of study unto themselves, and may be utilized to provide methodological insight into a variety of psychological domains., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Kapitany, Hampejs and Goldstein.)

Transition age youth (TAY), a demographic spanning ages 15-26, navigate a myriad of developmental transitions, ranging from identity formation and intimate relationships to substance use. Unfortunately, many young adults continue to have a dearth of mental health services and programing tailored to their unique developmental needs. Moreover, the systems of care in place are generally designed for treating traditional pediatric and adult patients but not ideally suited to meet the needs of TAY. Given the additional stressors from the COVID-19 pandemic, TAY are now, more than ever, in need of routine mental health care. We posit that the rapid expansion of telemedicine programming developed in response to the pandemic could be beneficial in mitigating this historic gap in care. In this commentary, we call on mental health providers and researchers to expand and invest in the growing number of telemedicine interventions and programming for this population so that TAY can begin to receive the care they so desperately need., (© 2022.

Preschool-aged children can learn from fictional, pretend, and imaginative activities. However, many studies showing this learning involve children as physically passive while consuming fictional narratives rather than as actively, physically engaged. Physical engagement may add to cognitive processes already at play when watching narratives, making children more likely to retain or understand information. Children's natural pretend involves physical movement, role play, and embodiment. To test learning from embodied pretense, we conducted two studies in which we experimentally manipulated whether children were physically passive while consuming narratives or physically actively engaged with them through embodied pretend play using puppets or costumes. In Study 1, children were shown/engaged in television-based narratives, all of which contained fantastical content. In Study 2, children were shown/engaged in lab-created stories, some of which contained fantastical elements. We measured children's learning and perceptions of realism. In Study 1, neither perception of fictionality nor embodiment immediately affected learning, although older preschoolers learned more than younger preschoolers. In Study 2, neither perception nor presence of fantastical content affected learning, but embodiment did. Children learned more from both embodied conditions compared with the physically passive condition. We also included 2-week follow-up tests of recall and found that although children retained very little, embodiment still affected retention in both studies. Overall, children did not use realism judgments to differentiate learning. These findings show the complexity of different elements involved in children's learning from pretense and the need to understand what elements affect learning from fantastical and embodied pretend play and stories., (Copyright © 2021 Elsevier Inc.

Given the consistently high viewership of television (TV) by youth, the social, behavioral, developmental, and psychological impact of such viewing has been studied for decades. Yet, little research has focused on the connections between youth, the TV shows to which they are exposed, and the characterizations of leadership presented to them. This study examines the type of leadership behaviors and orientations presented through youth TV shows in the United States across a continuum of viewership age targets. Shows were selected through purposeful sampling from the most popular youth TV shows in the United States, and episodes were chosen based on synopsis, selecting for the greatest possibility of leadership scenarios. Researchers identified three shows for each viewer target age group and five episodes for each TV show, for a total of 75 episodes. The findings include the discovery that show-prescribed viewer target age group positively predicted leadership behavior such as direction-setting-i.e., gathering information, organizing information, sense-making, and forecasting. Additionally, as viewer target age range increased, shows presented with a decrease in communal leadership-characterized as caring, warm, trustworthy, empathetic, helpful, and/or friendly. Such findings suggest that the representations of leadership depicted in popular youth TV shows are transmitting potentially counterproductive messages to future leaders, deprioritizing crucial leadership elements., (© 2021.

Background: The ability to predict an individual's risk of mood episode recurrence can facilitate personalized medicine in bipolar disorder (BD). We sought to externally validate, in an adult sample, a risk calculator of mood episode recurrence developed in youth/young adults with BD from the Course and Outcome of Bipolar Youth (COBY) study., Methods: Adult participants from the National Institute of Mental Health Collaborative Depression Study (CDS; N=258; mean(SD) age=35.5(12.0) years; mean follow-up=24.9 years) were utilized as a sample to validate the youth COBY risk calculator for onset of depressive, manic, or any mood episodes., Results: In this older validation sample, the risk calculator predicted recurrence of any episode over 1, 2, 3, or 5-year follow-up intervals, with Area Under the Curves (AUCs) approximating 0.77. The AUC for prediction of depressive episodes was about 0.81 for each of the time windows, which was higher than for manic or hypomanic episodes (AUC=0.72). While the risk calculator was well-calibrated across the range of risk scores, it systematically underestimated risk in the CDS sample by about 20%. The length of current remission was a highly significant predictor of recurrence risk in the CDS sample., Limitations: Predominantly self-reported White samples may limit generalizability; the risk calculator does not assess more proximal risk (e.g., 1 month)., Conclusions: Risk of mood episode recurrence can be predicted with good accuracy in youth and adults with BD in remission. The risk calculators may help identify higher risk BD subgroups for treatment and research., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Study Objectives: Structural brain maturation and sleep are complex processes that exhibit significant changes over adolescence and are linked to many physical and mental health outcomes. We investigated whether sleep-gray matter relationships are developmentally invariant (i.e. stable across age) or developmentally specific (i.e. only present during discrete time windows) from late childhood through young adulthood., Methods: We constructed the Neuroimaging and Pediatric Sleep Databank from eight research studies conducted at the University of Pittsburgh (2009-2020). Participants completed a T1-weighted structural MRI scan (sMRI) and 5-7 days of wrist actigraphy to assess naturalistic sleep. The final analytic sample consisted of 225 participants without current psychiatric diagnoses (9-25 years). We extracted cortical thickness and subcortical volumes from sMRI. Sleep patterns (duration, timing, continuity, regularity) were estimated from wrist actigraphy. Using regularized regression, we examined cross-sectional associations between sMRI measures and sleep patterns, as well as the effects of age, sex, and their interaction with sMRI measures on sleep., Results: Shorter sleep duration, later sleep timing, and poorer sleep continuity were associated with thinner cortex and altered subcortical volumes in diverse brain regions across adolescence. In a discrete subset of regions (e.g. posterior cingulate), thinner cortex was associated with these sleep patterns from late childhood through early-to-mid adolescence but not in late adolescence and young adulthood., Conclusions: In childhood and adolescence, developmentally invariant and developmentally specific associations exist between sleep patterns and gray matter structure, across brain regions linked to sensory, cognitive, and emotional processes. Sleep intervention during specific developmental periods could potentially promote healthier neurodevelopmental outcomes., (© Sleep Research Society 2021.

Objectives: While adults with bipolar disorder (BD) often report symptoms starting in childhood, continuity of mania and/or hypomania (mania/hypomania) from childhood to adulthood has been questioned. Using longitudinal data from the Course and Outcome of Bipolar Youth (COBY) study, we assessed threshold mania/hypomania in young adults who manifested BD as youth., Methods: COBY is a naturalistic, longitudinal study of 446 youth with BD (84% recruited from outpatient clinics), 7-17 years old at intake, and over 11 years of follow-up. Focusing on youth with BD-I/II (n = 297), we examined adult mania/hypomania risk (>18 years old; mean 7.9 years of follow-up) according to child (<13 years old) versus adolescent (13-17 years old) onset. We next used penalized regression to test demographic and clinical predictors of young adult mania/hypomania., Results: Most participants (64%) had child-onset mania/hypomania, 57% of whom also experienced mania/hypomania in adolescence. Among those who experienced an episode in adolescence, over 40% also had mania/hypomania during adulthood; the risk did not differ according to child versus adolescent onset. In contrast, 7% with mania/hypomania in childhood, but not adolescence, experienced mania/hypomania in adulthood. Family history (of mania and suicide attempts) predicted mania/hypomania in young adulthood (p-values <0.05); age of onset was not a significant predictor. Among participants with no mania/hypomania during adulthood, 53% (105/198) still experienced subthreshold manic episodes., Discussion: We find substantial continuity across developmental stage indicating that, in this carefully characterized sample, children who experience mania/hypomania-particularly those who also experience mania/hypomania in adolescence-are likely to experience mania/hypomania in young adulthood., (© 2020 John Wiley & Sons A/S.

Background: Youth with bipolar disorder (BD) are at high risk for suicidal thoughts and behaviors and frequently experience interpersonal impairment, which is a risk factor for suicide. Yet, no study to date has examined the longitudinal associations between relationship quality in family/peer domains and suicidal thoughts and behaviors among youth with BD. Thus, we investigated how between-person differences - reflecting the average relationship quality across time - and within-person changes, reflecting recent fluctuations in relationship quality, act as distal and/or proximal risk factors for suicidal ideation (SI) and suicide attempts., Methods: We used longitudinal data from the Course and Outcome of Bipolar Youth Study (N = 413). Relationship quality variables were decomposed into stable (i.e., average) and varying (i.e., recent) components and entered, along with major clinical covariates, into separate Bayesian multilevel models predicting SI and suicide attempt. We also examined how the relationship quality effects interacted with age and sex., Results: Poorer average relationship quality with parents (β = -.33, 95% Bayesian highest density interval (HDI) [-0.54, -0.11]) or friends (β = -.33, 95% HDI [-0.55, -0.11]) was longitudinally associated with increased risk of SI but not suicide attempt. Worsening recent relationship quality with parents (β = -.10, 95% HDI [-0.19, -0.03]) and, to a lesser extent, friends (β = -.06, 95% HDI [-0.15, 0.03]) was longitudinally associated with increased risk of SI, but only worsening recent relationship quality with parents was also associated with increased risk of suicide attempt (β = -.15, 95% HDI [-0.31, 0.01]). The effects of certain relationship quality variables were moderated by gender but not age., Conclusions: Among youth with BD, having poorer average relationship quality with peers and/or parents represents a distal risk factor for SI but not suicide attempts. Additionally, worsening recent relationship quality with parents may be a time-sensitive indicator of increased risk for SI or suicide attempt., (© 2020 Association for Child and Adolescent Mental Health.)

In this paper, we argue that in order for the study of arts education to continue to advance, we must delineate the effects of particular forms of arts education, offered in certain contexts, on specific domains of children's socioemotional development. We explain why formulating precise hypotheses about the effects of arts education on children's socioemotional development requires a differentiated definition of each arts education program or activity in question, as well as a consideration of both the immediate and broader contexts in which that program or activity occurs. We then offer the New Victory Theater's Schools with Performing Arts Reach Kids (SPARK) program as an illustrative example of how these considerations allow for the refinement of hypotheses about the impact of arts education on children's socioemotional development., Competing Interests: SH and DW were employed by company WolfBrown. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Holochwost, Goldstein and Wolf.)

Background: Pediatric bipolar disorders are often characterized by disruptions in cognitive functioning, and exposure to child maltreatment (e.g., physical and sexual abuse) is associated with a significantly poorer course of illness. Although clinical and developmental research has shown maltreatment to be robustly associated with poorer cognitive functioning, it is unclear whether maltreatment and cognitive function jointly influence the clinical course of bipolar symptoms., Methods: This secondary analysis examined moderating effects of lifetime childhood physical and sexual abuse, and cognitive disruptions (sustained attention, affective information processing), on longitudinal ratings of depression symptom severity in youths from the Course and Outcome of Bipolar Youth (COBY) study, examined from intake (M = 12.24 years) through age 22 (N = 198; 43.9% female; Mean age of bipolar onset = 8.85 years)., Results: A significant moderating effect was detected for sustained attention and maltreatment history. In the context of lower sustained attention, maltreatment exposure was associated with higher depression symptom severity during childhood, but not late adolescence. There was no association between maltreatment and symptom severity in the context of higher sustained attention, and no association between attention and depression symptom severity for non-maltreated youths., Limitations: Depression symptom ratings at each assessment were subject to retrospective recall bias despite the longitudinal design. Cognitive assessments were administered at different ages across youths., Conclusions: Depressive symptoms in pediatric bipolar may be jointly moderated by impairments in attention and exposure to maltreatment. Assessment of these risks, particularly in childhood, may be beneficial for considering risk of recurrence or chronicity of depressive symptoms., (Copyright © 2020. Published by Elsevier B.V.)

Background: In youth at familial risk for bipolar disorder (BD), mood lability is an important precursor to BD onset. Previous work in adults indicates that mindfulness-based interventions (MBI) may improve emotion regulation, in part by increasing resting-state functional connectivity (rsFC) between posterior cingulate cortex (PCC) and executive control network (ECN). In this pilot study, we assessed effects of an MBI on PCC-ECN rsFC and mood lability in at-risk youth., Methods: We recruited 35 youth (10-14 years old) with a first-degree family history of BD and mood lability, and 21 age-matched healthy controls. Eligible at-risk youth were scanned pre/post an 8-week MBI and assessed three months later. Healthy controls were scanned at matched timepoints but did not participate in the MBI. The MBI used age-appropriate strategies to promote non-judgmental, present-moment awareness. We assessed pre/post changes in PCC-ECN rsFC and how rsFC changes were related to mood outcomes., Results: Twenty at-risk youth were scanned pre/post MBI; 16 had high-quality rsFC data. Following MBI, at-risk youth showed increased rsFC between PCC and left dorsolateral prefrontal cortex (DLPFC) (BA 9; k = 28; corrected p=.006); healthy controls did not show this increase. Following MBI, at-risk youth reported more mindfulness (F = 7.15, p=.003), less mood lability (F = 7.2, p=.002), and less suppression of negative emotions (F = 5.05, p=.01). PCC-DLPFC rsFC increases predicted less mood lability (t=-2.25, p=.04) and less emotion suppression (t=-2.75, p=.02) at follow-up., Limitations: Small sample and lack of a control intervention., Conclusions: PCC-DLPFC rsFC may be a clinically meaningful neural target of an MBI in at-risk youth, related to improvements in mood lability., (Copyright © 2020 Elsevier B.V.

Objective: Despite substantial literature on sex differences in adults with bipolar disorder (BD), little is known about this topic in youth; this study examines sex differences in mood symptomatology and psychiatric comorbidity in prospectively followed youth with BD., Methods: A subsample of the Course and Outcome of Bipolar Youth study (N = 370; female n = 199, male n = 171) enrolled October 2000-July 2006 (age at intake = 7-17.11 years) who met DSM-IV criteria for bipolar I disorder (BD-I; n = 221), bipolar II disorder (BD-II; n = 26), or operationalized BD not otherwise specified (BD-NOS; n = 123) with ≥ 4 years follow-up was included. Analyses examined sex differences at intake and, prospectively, in mood symptomatology and psychiatric comorbidity for a mean ± SD follow-up of 10.5 ± 1.72 years., Results: Females were older than males at intake (mean ± SD age = 13.33 ± 3.32 vs 12.04 ± 3.16 years; P = .0002) and at age at mood onset (9.33 ± 4.22 vs 7.53 ± 3.74 years; P < .0001). After adjustment for confounders, males spent more time with syndromal ADHD (Padjusted = .001) and females spent more time with syndromal anxiety (Padjusted = .02). There were trends toward males spending more time with substance use disorder and females having more non-suicidal self-injurious behavior (Padjusted = .07 and .09, respectively). There were no sex differences on outcome variables, including rate of or time to recovery and recurrence., Conclusions: Contrasting with adult literature, this study identified minimal sex differences in the course of youth with BD. Longer-term studies are needed to clarify if youth-onset BD remains a "sex neutral" subtype of BD or diverges according to sex in adulthood., (© Copyright 2020 Physicians Postgraduate Press, Inc.)

Objective: Lithium is the mainstay for bipolar disorder (BD) treatment in adults, but evidence in youths is limited. We used data from the Course and Outcome of Bipolar Youth (COBY) study to assess whether lithium vs other mood-stabilizing medication (OMS) was associated with improved outcomes, including mood symptoms and suicidality., Method: COBY is a naturalistic, longitudinal study of 413 youths, 7 to 17.11 years old at intake, with BD. At each visit, medication exposure, psychiatric symptoms, and psychosocial function over the preceding follow-up period were assessed using the Adolescent Longitudinal Interval Follow-Up Evaluation. Using mixed models, we determined whether participants taking lithium vs OMS (but not lithium) differed regarding mood symptoms, suicidality, psychosocial function, hospitalization, aggression, and substance use., Results: A total of 340 participants contributed 2,638 six-month follow-up periods (886 lithium, 1,752 OMS), over a mean follow-up of 10 years. During lithium (vs OMS) follow-up periods, participants were older, less likely to have lifetime anxiety, and less likely to be on antidepressants (p values<.005). After covariate adjustment, the lithium group (vs OMS) had half as many suicide attempts (p = .03), fewer depressive symptoms (p = .004), less psychosocial impairment (p = .003), and less aggression (p = .0004). Similar findings were observed in the subgroup of follow-up periods in which participants were <18 years old., Conclusion: Findings are consistent with adult studies, showing that lithium is associated with decreased suicidality, less depression, and better psychosocial functioning. Given the paucity of evidence regarding lithium in children and adolescents, these findings have important clinical implications for the pharmacological management of youths with BD., (Copyright © 2019 American Academy of Child and Adolescent Psychiatry.

Background: Exposure to severe Traumatic Events (TEs) has been associated with poor course and outcomes among individuals with Bipolar Disorder (BD). However, there is limited research on TEs among youth with BD, and few studies are longitudinal. This study prospectively followed a large sample of BD youth, examining the associations of lifetime TEs with their mood and functioning., Methods: BD participants (n=375; mean age=17; range 8-25y) were assessed, on average, every 7 months for a median 8.7 years. Psychopathology and lifetime trauma history were prospectively evaluated using the Longitudinal Interval Follow-Up Evaluation, and a traumatic events screening., Results: Accounting for covariates, participants with one or more lifetime TEs (84%) showed earlier BD onset, poorer psychosocial functioning, worse mood symptoms, and more suicidal ideation, comorbidities, and family psychopathology than those without TEs. TEs during recovery periods increased recurrence risk (p<0.02). More TEs were associated with poorer mood course, particularly among victims of violence/abuse (p<0.02). Abused participants (34% physical; 17% sexual) showed earlier onset of substance use disorders, more suicidality and comorbidities compared to those without abuse. Comparisons of mood course before and after abuse occurred, and with participants without abuse, showed worsening mood symptoms after, specifically hypo/mania (p<0.03)., Limitations: Prospective data was gathered longitudinally but assessed retrospectively at every follow-up; given approximate dates causality cannot be inferred; TEs severity was not assessed., Conclusions: Severe TEs, particularly abuse, were associated with poorer course and outcomes among BD youth. Prompt screening of trauma and early intervention may be warranted to minimize TEs impact., Competing Interests: Declaration of Competing Interest Dr. Andreu Pascual has received a grant from the Alicia Koplowitz Foundation.
