BackgroundTrichotillomania (TTM) and skin picking disorder (SPD) are common and often debilitating mental health conditions, grouped under the umbrella term of body-focused repetitive behaviors (BFRBs). Recent clinical subtyping found that there were three distinct subtypes of TTM and two of SPD. Whether these clinical subtypes map on to any unique neurobiological underpinnings, however, remains unknown.MethodsTwo hundred and fifty one adults [193 with a BFRB (85.5% [n = 165] female) and 58 healthy controls (77.6% [n = 45] female)] were recruited from the community for a multicenter between-group comparison using structural neuroimaging. Differences in whole brain structure were compared across the subtypes of BFRBs, controlling for age, sex, scanning site, and intracranial volume.ResultsWhen the subtypes of TTM were compared, low awareness hair pullers demonstrated increased cortical volume in the lateral occipital lobe relative to controls and sensory sensitive pullers. In addition, impulsive/perfectionist hair pullers showed relative decreased volume near the lingual gyrus of the inferior occipital-parietal lobe compared with controls.ConclusionsThese data indicate that the anatomical substrates of particular forms of BFRBs are dissociable, which may have implications for understanding clinical presentations and treatment response.

Beginning college involves changes that can increase one's vulnerability to loneliness and associated negative outcomes. Parent and friend relationships are potential protective factors against loneliness given their positive association with adjustment. The present longitudinal study, with data collection at baseline, 1 month, and 2 months later, assessed the comparative effects of self-reported parent and friend relationship quality on loneliness in first-year college students (N = 101; 80 female, Mage = 18.36). At baseline, parent and friend relationship quality were negatively associated with loneliness. Longitudinal data revealed that friend relationship quality interacted with time, such that its effects on loneliness attenuated over the course of 2 months. By contrast, parent relationship quality continued to predict lower loneliness 2 months post-baseline. These results highlight the importance of close relationships and suggest that targeting relationship quality could be effective in helping youth transition to college.

ObjectiveCommonly-used youth anxiety measures may not comprehensively capture fears, worries, and experiences related to the pervasive impact of the COVID-19 pandemic. This study described the development of the Fear of Illness and Virus Evaluation (FIVE) scales and validated the caregiver-report version.MethodAfter initial development, feedback was obtained from clinicians and researchers, who provided suggestions on item content/wording, reviewed edits, and provided support for the updated FIVE's content and face validity. Factor structure, measurement invariance, and psychometric properties were analyzed using data from a multi-site, longitudinal study of COVID-19-related effects on family functioning with 1599 caregivers from the United States and Canada.ResultsConfirmatory factor analyses indicated a hierarchical five-factor structure best fit the data, resulting in a 31-item measure with four lower-order subscales: (1) Fears about Contamination and Illness; (2) Fears about Social Distancing, (3) Avoidance Behaviors, and (4) Mitigation Behaviors, and a higher-order factor, (5) Total Fears, indicated by the two fear-related lower-order subscales. Measurement invariance by country of residence, child age, and child sex was found. All subscales demonstrated strong internal consistency, appropriate item-scale discrimination, and no floor or ceiling effects. The Total Fears subscale demonstrated appropriate test-retest reliability. Concurrent validity supported by strong correlation with a youth anxiety measure.DiscussionThe FIVE provides a psychometrically-sound measure of COVID-19-related fears and behaviors in youth in a caregiver-report format. Future research is necessary to evaluate correlates and longitudinal symptom patterns captured by the FIVE caregiver-report, as well as the validity and reliability of a youth self-report version of the FIVE.

Disorders such as Trichotillomania (TTM) and skin-picking disorder (SPD) are associated with reduced flexibility and increased internally focused attention. While the basal ganglia have been hypothesized to play a key role, the mechanisms underlying learning and flexible accommodation of new information is unclear. Using a Bayesian Learning Model, we evaluated the neural basis of learning and accommodation in individuals with TTM and/or SPD. Participants were 127 individuals with TTM and/or SPD (TTM/SPD) recruited from three sites (age 18-57, 84% female) and 26 healthy controls (HC). During fMRI, participants completed a shape-button associative learning and reversal fMRI task. Above-threshold clusters were identified where the Initial Learning-Reversals BOLD activation contrast differed significantly (p

Nearly a year into the COVID-19 pandemic, conversations about the impact of COVID-19 on children and families have shifted. Initial advice for parents stressed topics such as how to talk about the pandemic with children or cope with illness-related distress. They now focus on youth adjustment to a heavily disrupted school year and on strategies for building long-term resilience. Although these conversations often center on youth adjustment, they have-at last-started to consider the well-being of parents (and other caregivers) as well. This shift in focus is crucial given the enormous challenges that parents face right now and the direct links between their well-being and that of their children. What continues to lag, even well into the pandemic, however, is the provision of workable solutions for addressing parents' mental health. While we applaud the renewed focus on parenting stress and well-being, we remain deeply concerned by the absence of a plan for intervening.

Body-focused repetitive behavior disorders (BFRBs) include Trichotillomania (TTM; Hair pulling disorder) and Excoriation (Skin Picking) Disorder (SPD). These conditions are prevalent, highly heterogeneous, under-researched, and under-treated. In order for progress to be made in optimally classifying and treating these conditions, it is necessary to identify meaningful subtypes. 279 adults (100 with TTM, 81 with SPD, 40 with both TTM and SPD, and 58 controls) were recruited for an international, multi-center between-group comparison using mixture modeling, with stringent correction for multiple comparisons. The main outcome measure was to examine distinct subtypes (aka latent classes) across all study participants using item-level data from gold-standard instruments assessing detailed clinical measures. Mixture models identified 3 subtypes of TTM (entropy 0.98) and 2 subtypes of SPD (entropy 0.99) independent of the control group. Significant differences between these classes were identified on measures of disability, automatic and focused symptoms, perfectionism, trait impulsiveness, and inattention and hyperactivity. These data indicate the existence of three separate subtypes of TTM, and two separate subtypes of SPD, which are distinct from controls. The identified clinical differences between these latent classes may be useful to tailor future treatments by focusing on particular traits. Future work should examine whether these latent subtypes relate to treatment outcomes, or particular psychobiological findings using neuroimaging techniques.

Avoidant behavior is a defining feature of pediatric anxiety disorders. Although prior research has examined it from the perspective of early information processing events, there has been relatively less consideration of the processes by which anxious youth make avoidant decisions and how these choices are reinforced over time. Studies of risk taking are valuable in this regard because they consider how individuals identify the pros and cons of their choices, how they weigh potential gains and losses and estimate their respective probabilities, and how they tolerate the uncertainty intrinsic to any decision. In this review, we place risk taking within existing models of information processing in pediatric anxiety disorders and highlight the particular value of this construct for informing models of developmental psychopathology and individual differences in outcome over time. We review existing behavioral and neurobiological studies of risk taking in anxious youth and conclude by identifying directions for future research.

This study examined the relationship between caregivers' and youths' treatment expectations and characteristics of exposure tasks (quantity, mastery, compliance) in cognitive-behavioral therapy (CBT) for childhood anxiety. Additionally, compliance with exposure tasks was tested as a mediator of the relationship between treatment expectations and symptom improvement. Data were from youth (N = 279; 7-17 years old) enrolled in the Child/Adolescent Anxiety Multimodal Study (CAMS) and randomized to cognitive-behavioral therapy (CBT) or the combination of CBT and sertraline for the treatment of separation anxiety disorder, generalized anxiety disorder, and social phobia. Caregivers and youth independently reported treatment expectations prior to randomization, anxiety was assessed pre- and post-treatment by independent evaluators blind to treatment condition, and exposure characteristics were recorded by the cognitive-behavioral therapists following each session. For both caregivers and youths, more positive expectations that anxiety would improve with treatment were associated with greater compliance with exposure tasks, and compliance mediated the relationship between treatment expectations and change in anxiety symptoms following treatment. Additionally, more positive parent treatment expectations were related to a greater number and percentage of sessions with exposure. More positive youth treatment expectations were associated with greater mastery during sessions focused on exposure. Findings underscore the importance of addressing parents' and youths' treatment expectations at the outset of therapy to facilitate engagement in exposure and maximize therapeutic gains.

Pediatric obsessive-compulsive disorder (OCD) co-occurs frequently with other mental health conditions, adding to the burden of disease and complexity of treatment. Cognitive behavioral therapy (CBT) is efficacious for both OCD and two of its most common comorbid conditions, anxiety and depression. Therefore, treating OCD may yield secondary benefits for anxiety and depressive symptomatology. This study examined whether anxiety and/or depression symptoms declined over the course of OCD treatment and, if so, whether improvements were secondary to reductions in OCD severity, impairment, and/or global treatment response. The sample consisted of 137 youths who received 12 sessions of manualized CBT and were assessed by independent evaluators. Mixed models analysis indicated that youth-reported anxiety and depression symptoms decreased in a linear fashion over the course of CBT, however these changes were not linked to specific improvements in OCD severity or impairment but to global ratings of treatment response. Results indicate that for youth with OCD, CBT may offer benefit for secondary anxiety and depression symptoms distinct from changes in primary symptoms. Understanding the mechanisms underlying carryover in CBT techniques is important for furthering transdiagnostic and/or treatment-sequencing strategies to address co-occurring anxiety and depression symptoms in pediatric OCD.

Repetitive behaviors are observed in autism spectrum disorder and obsessive-compulsive disorder. Clinically, obsessive-compulsive disorder obsessions are thought to drive repetitive or ritualistic behavior designed to neutralize subjective distress, while restricted and repetitive behaviors are theorized to be reward- or sensory-driven. Both behaviors are notably heterogeneous and often assessed with parent- or clinician-report, highlighting the need for multi-informant, multi-method approaches. We evaluated the relationship between parent- and child self-reported obsessive-compulsive disorder symptoms with parent-reported and clinician-indexed restricted and repetitive behaviors among 92 youth with autism spectrum disorder (ages 7-17years). Regression analyses controlling for the social communication and interaction component of parent-reported autism spectrum disorder symptoms indicated child self-reported, but not parent-reported, symptoms of obsessive-compulsive disorder were associated with clinician-observed restricted and repetitive behaviors. Although both parent- and child self-reported obsessive-compulsive disorder symptoms were associated with parent-reported restricted and repetitive behaviors, the overlap between parent-reports of obsessive-compulsive disorder symptoms and restricted and repetitive behaviors were likely driven by their shared method of parent-reported measurement. Results suggest that children experience restricted and repetitive behaviors in ways that more closely resemble traditional obsessive-compulsive disorder-like compulsions, whereas their parents view such behaviors as symptoms of autism spectrum disorder. These findings provide guidance for better understanding, distinguishing, and ultimately treating obsessive-compulsive disorder behavior in youth with autism spectrum disorder and introduce new conceptualizations of the phenotypic overlap between these conditions.

BackgroundChildhood obsessive-compulsive disorder (OCD) is a heterogeneous psychiatric condition, with varied symptom presentations that have been differentially associated with clinical characteristics and treatment response. One OCD symptom cluster of particular interest is religious symptoms, including fears of offending religious figures/objects; patients affected by these symptoms have been characterized as having greater overall OCD severity and poorer treatment response. However, the extant literature primarily examines this symptom subtype within adults, leaving a gap in our understanding of this subtype in youth.MethodConsequently, this study examined whether presence of religious symptoms in OCD-affected children and adolescents (N = 215) was associated with greater clinical impairments across OCD symptoms and severity, insight, other psychiatric comorbidity, family variables, or worse treatment response.ResultsResults found that youth with religious OCD symptoms presented with higher OCD symptom severity and exhibited more symptoms in the aggressive, sexual, somatic, and checking symptom cluster, as well as the symmetry, ordering, counting, and repeating cluster. Religious OCD symptoms were also significantly associated with poorer insight and higher family expressiveness. No differences in treatment response were observed in youths with versus without religious OCD symptoms.ConclusionUltimately, youths with religious OCD symptoms only differed from their OCD-affected counterparts without religious symptoms on a minority of clinical variables; this suggests they may be more comparable to youths without religious OCD symptoms than would be expected based on the adult OCD literature and highlights the importance of examining these symptoms within a pediatric OCD sample.

ObjectiveAlthough evidence-based treatments for pediatric obsessive-compulsive disorder (OCD) exist, many youth fail to respond, and interventions tailored to the needs of specific subsets of patients are lacking. This study examines the efficacy of a family intervention module designed for cases of OCD complicated by poor family functioning.MethodParticipants were 62 youngsters aged 8 to 17 years (mean age = 12.71 years; 57% male; 65% white) with a primary diagnosis of OCD and at least 2 indicators of poor family functioning. They were randomized to receive 12 sessions of individual child cognitive-behavioral therapy (CBT) plus weekly parent psychoeducation and session review (standard treatment [ST]) or the same 12 child sessions plus 6 sessions of family therapy aimed at improving OCD-related emotion regulation and problem solving (positive family interaction therapy [PFIT]). Blinded raters evaluated outcomes and tracked responders to 3-month follow-up.ResultsCompared to ST, PFIT demonstrated better overall response rates on the Clinician Global Impression-Improvement scale (CGI-I; 68% versus 40%, p = .03, φ = 0.28) and rates of remission (58% PFIT versus 27% ST, p = .01, φ = 0.32). PFIT also produced significantly greater reductions in functional impairment, symptom accommodation, and family conflict, and improvements in family cohesion. As expected, these shifts in family functioning constitute an important treatment mechanism, with changes in accommodation mediating treatment response.ConclusionPFIT is efficacious for reducing OCD symptom severity and impairment and for improving family functioning. Findings are discussed in terms of personalized medicine and mechanisms of change in pediatric OCD treatment.

Background: Substance use problems and anxiety disorders are both highly prevalent and frequently cooccur in youth. The present study examined the benefits of successful anxiety treatment at 3–12 years after treatment completion on substance use outcomes (i.e. diagnoses and lifetime expected use). Methods: The sample was from the Child/Adolescent Anxiety Multimodal Extended Long‐term Study (CAMELS), a naturalistic follow‐up study to the Child/Adolescent Anxiety Multimodal Study (CAMS) which randomized youth to cognitive behavioral therapy (CBT; Coping cat), medication (sertraline), their combination, or pill placebo. The first CAMELS visit occurred an average of 6.5 years following CAMS randomization. Participants were 319 youth (65.4% of the CAMS sample), aged 7–17 years at CAMS baseline assessment with a mean age of 17.6 years (range: 11–26 years) at the time of the first CAMELS follow‐up. Substance use outcomes included diagnoses as well as lifetime substance use (i.e. alcohol and tobacco use). Results: Eleven of 319 (3.4%) CAMELS participants were diagnosed with a substance use disorder at the initial follow‐up visit. When compared to the population lifetime rate of 11.4%, the rate of diagnoses in the posttreated sample was significantly lower. Additionally, rates of lifetime alcohol use were lower than population rates at the initial and final follow‐up visits. Rates of lifetime tobacco use were similarly lower than lifetime population rates at the initial visit (driven by significantly lower rates in the CBT treatment condition), but higher by the final visit. Furthermore, treatment remission (but not treatment response) was associated with a lower rate of substance use diagnoses at the initial follow‐up visit, although rates of lifetime alcohol and tobacco use did not differ by treatment outcome. Conclusions: Anxiety treatments confer a beneficial impact on problematic substance use (i.e. diagnoses) as well as on expected substance use (i.e. alcohol and tobacco use) for on average, a period of 6.5 years.

Levels of parental expressed emotion (EE) are prospectively associated with the symptomatic course of a range of childhood psychiatric disorders. This article reviews the literature linking parental EE to youth psychopathology and proposes a novel framework for understanding its mechanisms of action. We find that, despite noteworthy methodological limitations, parental EE is linked consistently to a more deleterious course of mood, anxiety, and psychotic disorders in youth. Its mechanism of action is unknown. Models of "toxic family stress" (referring to frequent, sustained, and uncontrollable stress without protective influences) provide one framework for understanding how high EE environments interact with individual biological vulnerabilities to promote illness onset and recurrence. Research aimed at understanding biological responses (e.g., stress reactivity, arousal) to familial EE is needed. Such work may inform efforts to understand how EE affects the course of psychiatric disorders and may guide the development of novel interventions emphasizing emotion regulation strategies.

We evaluated the construct validity of the Child Yale-Brofwn Obsessive-Compulsive Scale (CYBOCS) in a large clinical sample (N=730) using confirmatory factor analysis. Results found inadequate fit for a priori models, though a model accounting for overlapping item content displayed good fit. Parallel obsessions/compulsions items may provide largely redundant information on the CYBOCS. Findings suggest modifying the CYBOCS to reduce burden on researchers, patients, and clinicians, and to more accurately measure pediatric obsessive-compulsive disorder (OCD).

ObjectiveTo evaluate changes in the trajectory of youth anxiety following the introduction of specific cognitive-behavior therapy (CBT) components: relaxation training, cognitive restructuring, and exposure tasks.MethodFour hundred eighty-eight youths ages 7-17 years (50% female; 74% ≤ 12 years) were randomly assigned to receive either CBT, sertraline (SRT), their combination (COMB), or pill placebo (PBO) as part of their participation in the Child/Adolescent Anxiety Multimodal Study (CAMS). Youths in the CBT conditions were evaluated weekly by therapists using the Clinical Global Impression Scale-Severity (CGI-S; Guy, 1976) and the Children's Global Assessment Scale (CGAS; Shaffer et al., 1983) and every 4 weeks by blind independent evaluators (IEs) using the Pediatric Anxiety Ratings Scale (PARS; RUPP Anxiety Study Group, 2002). Youths in SRT and PBO were included as controls.ResultsLongitudinal discontinuity analyses indicated that the introduction of both cognitive restructuring (e.g., changing self-talk) and exposure tasks significantly accelerated the rate of progress on measures of symptom severity and global functioning moving forward in treatment; the introduction of relaxation training had limited impact. Counter to expectations, no strategy altered the rate of progress in the specific domain of anxiety that it was intended to target (i.e., somatic symptoms, anxious self-talk, avoidance behavior).ConclusionsFindings support CBT theory and suggest that cognitive restructuring and exposure tasks each make substantial contributions to improvement in youth anxiety. Implications for future research are discussed. (PsycINFO Database Record

The aim of this investigation was to evaluate how parental anxiety predicted change in pediatric anxiety symptoms across four different interventions: cognitive-behavioral therapy, medication (sertraline; SRT), their combination (COMB), and pill placebo. Participants were 488 youths (ages 7-17) with separation anxiety disorder, generalized anxiety disorder, and/or social phobia and their primary caregivers. Latent growth curve modeling assessed how pre-treatment parental trait anxiety symptoms predicted trajectories of youth anxiety symptom change across 12 weeks of treatment at four time points. Interactions between parental anxiety and treatment condition were tested. Parental anxiety was not associated with youth's pre-treatment anxiety symptom severity. Controlling for parental trait anxiety, youth depressive symptoms, and youth age, youths who received COMB benefitted most. Counter to expectations, parental anxiety influenced youth anxiety symptom trajectory only within the SRT condition, whereas parental anxiety was not significantly associated with youth anxiety trajectories in the other treatment conditions. Specifically, within the SRT condition, higher levels of parental anxiety predicted a faster and greater reduction in youth anxiety over the acute treatment period compared to youths in the SRT condition whose parents had lower anxiety levels. While all active treatments produced favorable outcomes, results provide insight regarding the treatment-specific influence of parental anxiety on the time course of symptom change.

ObjectiveWe sought to examine predictors and moderators of treatment outcomes among 488 youths ages 7-17 years (50% female; 74% ≤ 12 years) meeting Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; American Psychiatric Association, 2000) criteria for diagnoses of separation anxiety disorder, social phobia, or generalized anxiety disorder who were randomly assigned to receive either cognitive behavioral therapy (CBT), sertraline (SRT), their combination (COMB), or medication management with pill placebo (PBO) in the Child/Adolescent Anxiety Multimodal Study (CAMS).MethodSix classes of predictor and moderator variables (22 variables) were identified from the literature and examined using continuous (Pediatric Anxiety Ratings Scale; PARS) and categorical (Clinical Global Impression Scale-Improvement; CGI-I) outcome measures.ResultsThree baseline variables predicted better outcomes (independent of treatment condition) on the PARS, including low anxiety severity (as measured by parents and independent evaluators) and caregiver strain. No baseline variables were found to predict Week 12 responder status (CGI-I). Participants' principal diagnosis moderated treatment outcomes but only on the PARS. No baseline variables were found to moderate treatment outcomes on Week 12 responder status (CGI-I).DiscussionOverall, anxious children responded favorably to CAMS treatments. However, having more severe and impairing anxiety, greater caregiver strain, and a principal diagnosis of social phobia were associated with less favorable outcomes. Clinical implications of these findings are discussed.
