Background: The failure to regulate emotions, namely emotional dysregulation (ED), is a relevant construct in adolescent psychiatry, in terms of prognostic and developmental implications. We developed and validated a novel self-report questionnaire for the assessment of ED, the RIPoSt-Y, both in clinical and non-clinical samples., Methods: Items selection and subscales construction were conducted on healthy controls (n=374), while test-retest reliability was evaluated in a subsample (n=72); internal consistency was examined both in the control group and in two clinical samples, respectively including patients with Bipolar Spectrum Disorders (BSD; n=44) and ADHD (n=34). Construct, concurrent and convergent validity were also assessed., Results: Thirty-one items were finally retained, and three subscales were identified (Affective Instability, Emotional Reactivity, Interpersonal Sensitivity). Test-retest was significant for each subscale with moderate-to-good correlations, and internal consistency showed good-to-excellent coefficients. Construct validity was supported by significant differences between patients and controls and gender-related differences. Concurrent validity was confirmed through significant associations with two subscales of the CHT-Q, while convergent validity proved to be significant with the CBCL/YSR dysregulation-profile. Cut-offs were also computed to discriminate clinically significant scores of ED., Limitations: The use of a school-based survey to recruit controls could have biased our results; gender distributions between clinical and non-clinical samples were significantly different., Conclusions: Our novel questionnaire proved to be a valid and reliable tool able to assess the presence of ED in youths and to characterize this fundamental construct in its multidimensional facets., (Copyright © 2021.

Background: Growing evidence supports the comorbidity between bipolar disorder (BD) and obsessive-compulsive disorder (OCD) in children and adolescents. Our aim is to further explore clinical and treatment implications of this comorbidity, as it appears in clinical practice., Method: The sample included 429 consecutive patients with BD and/or OCD as primary diagnoses, followed for a mean period of 6 months (range 4-9 months), 172 with BD (102 males, mean age 13.7±2.9 years), 169 with OCD (118 males, mean age of 13.2±2.7 years) and 88 with comorbid BD+OCD (56 males, mean age 14.2±2.6 years, 52 with BD as the primary diagnosis), followed for a mean period of 6 months (range 4-9 months). The comorbid group was compared to pure BD and OCD groups, to explore differential clinical and treatment features., Results: The BD-OCD comorbidity was found in 33.8% of the BD patients and in 34.2% of the OCD patients. Age at onset of BD and OCD were not different in pure and "comorbid" groups. The comorbid group presented a higher occurrence of BD type II and hoarding symptoms, and more frequently received a psychotherapy and second generation antipsychotics, but it presented the poorest outcome in terms of response to treatments. Severity at baseline (clinical severity and functional impairment), hoarding obsessions and compulsions, and conduct disorder comorbidity were associated with a treatment non-response., Limitations: A selection bias may have increased the rate of comorbidity, as most of the patients were referred to our tertiary hospital for severe BD and/or OCD and pharmacological treatment. We have used CGI-I as an outcome measure, not a specific measure of BD or OCD symptoms' severity and improvement. The short duration of the follow-up may limit our conclusions., Conclusions: The timely identification of BD-OCD comorbidity may have relevant clinical implications in terms of symptomatology, course, treatment and outcome., (Copyright © 2018 Elsevier B.V.

This study reports on the naturalistic pharmacotherapy of 266 youths with bipolar disorder (BP), manic or hypomanic episode (158 males and 108 females, 13.8+/-2.8 years), first treated with monotherapy on valproic acid (VPA) (n=158, 59.4%), lithium (n=90, 33.8%) or atypical antipsychotics (n=18, 6.8%). Among the patients receiving mood stabilizers, 59.5% of those treated with VPA and 47.8% of those receiving lithium did not need other antimanic agents (mood stabilizers and/or atypical antipsychotics). Lower severity was associated with a greater persistence of both VPA and lithium monotherapy. Factors associated with greater persistence of VPA monotherapy were BP II and co-occurring generalized anxiety disorder, separation anxiety disorder and simple phobias. On the contrary, BP I and co-occurring psychotic symptoms and/or conduct disorder were associated with a lower persistence of VPA monotherapy. Factors associated with lower persistence of lithium monotherapy were younger age and the association with attention deficit hyper-activity disorder (ADHD). Type of BP and presence of psychotic symptoms and conduct disorder did not affect the lithium monotherapy. Overall, predictors of non-response (multiple stepwise logistic regression) in both VPA and lithium groups were baseline Clinical Global Impression (CGI) Severity score and comorbid conduct disorder; while psychotic symptoms and absence of comorbid generalized anxiety disorder were predictors of poorer treatment response only in the VPA group, and chronic course, comorbid ADHD and absence of comorbid panic disorder were predictors only in the lithium group. Such naturalistic data from an ordinary clinical setting have relevance to clinical practice., (Copyright 2009 Elsevier Ireland Ltd. All rights reserved.)

A substantial portion of patients with juvenile bipolar disorder (BD) have a comorbid panic disorder (PD). The aim of our study was to analyze the cross-sectional and longitudinal implications of such comorbidity in children and adolescents with BD. The sample comprised 224 referred children and adolescents with BD, 140 males (62.5%) and 84 females (37.5%), mean age 13.8+/-2.8 years, diagnosed with a clinical interview (K-SADS-PL), and followed up naturalistically for 6 months. Fifty-one BD patients (22.8%) had a lifetime diagnosis of comorbid PD. Subjects with BD+PD and those without BD (BD-noPD) did not differ according to index age, age at onset of BD and bipolar phenotype (episodic vs. continuous course, irritable vs. elated mood). BD+PD was more frequent in females, was less severe at baseline according to the Clinical Global Impression severity score, and was more frequently associated with BD type 2. Moreover, BD+PD presented higher rates of comorbid anxiety disorders (namely separation anxiety disorder) and lower rates of externalizing disorders, namely attention deficit disorder (ADHD) than BD-noPD. However, this different pattern of externalizing comorbidity did not affect severity and improvement. Our findings suggest that PD is frequently comorbid in juvenile BD and can influence severity, pattern of comorbidity and course of BD. The data are compatible with the hypothesis that Panic-BD and ADHD-BD might represent distinct developmental pathways of bipolar disorder. Further research on this question may prove rewarding.
