ABSTRACT
OBJECTIVE: A lack of universal definitions for response and remission in pediatric obsessive-compulsive disorder (OCD) has hampered the comparability of results across trials. To address this problem, we conducted an individual participant data diagnostic test accuracy meta-analysis to evaluate the discriminative ability of the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) in determining response and remission. We also aimed to generate empirically derived cutoffs on the CY-BOCS for these outcomes. METHOD: A systematic review of PubMed, PsycINFO, Embase and CENTRAL identified 5,401 references; 42 randomized controlled clinical trials were considered eligible, and 21 provided data for inclusion (N = 1,234). Scores of ≤2 in the Clinical Global Impressions Improvement and Severity scales were chosen to define response and remission, respectively. A 2-stage, random-effects meta-analysis model was established. The area under the curve (AUC) and the Youden Index were computed to indicate the discriminative ability of the CY-BOCS and to guide for the optimal cutoff, respectively. RESULTS: The CY-BOCS had sufficient discriminative ability to determine response (AUC = 0.89) and remission (AUC = 0.92). The optimal cutoff for response was a ≥35% reduction from baseline to posttreatment (sensitivity = 83.9, 95% CI = 83.7-84.1; specificity = 81.7, 95% CI = 81.5-81.9). The optimal cutoff for remission was a posttreatment raw score of ≤12 (sensitivity = 82.0, 95% CI = 81.8-82.2; specificity = 84.6, 95% CI = 84.4-84.8). CONCLUSION: Meta-analysis identified empirically optimal cutoffs on the CY-BOCS to determine response and remission in pediatric OCD randomized controlled clinical trials. Systematic adoption of standardized operational definitions for response and remission will improve comparability across trials for pediatric OCD.

Introduction Changes in social interactions following psychiatric hospitalization, a period characterized by heightened suicide risk, are important to understand. OBJECTIVE: We qualitatively explored perceived changes in social interactions one month after inpatient psychiatric discharge following a suicidal crisis. METHODS: A total of 113 United States Service members, recruited in the context of a psychotherapy randomized controlled trial, described the extent to which social interactions with family members, peers, and military commanders had changed. RESULTS: Most participants (82.3%) reported at least some change in social interactions, conveying six common themes. Showing more care and checking in more were frequently reported for family (24.8%, 20.4%), commanders (23.0%, 16.8%), and by peers (12.4%, 10.6%). Showing more concern was most frequently reported for family (13.3%) followed by peers (6.2%) and commanders (6.2%). Participants reported showing more caution from peers (14.2%), commanders (13.3%) and family (6.2%). Acting more distant was reported from commanders (7.1%), peers (7.1%), and family (5.3%). Showing negative reaction(s) was reported from commanders (8.0%), family (3.5%) and rarely for peers (0.9%). CONCLUSION: Inpatient providers are encouraged to prepare patients for potential changes in social interactions following psychiatric discharge and how to best respond to these changes.
ABSTRACT
The ability to maximize rewards and minimize the costs of obtaining them is vital to making advantageous explore/exploit decisions. Exploratory decisions are theorized to be greater among individuals with attention-deficit/hyperactivity disorder (ADHD), potentially due to deficient catecholamine transmission. Here, we examined the effects of ADHD status and methylphenidate, a common ADHD medication, on explore/exploit decisions using a 6-armed bandit task. We hypothesized that ADHD participants would make more exploratory decisions than controls, and that MPH would reduce group differences. On separate study days, adults with (n = 26) and without (n = 23) ADHD completed the bandit task at baseline, and after methylphenidate or placebo in counter-balanced order. Explore/exploit decisions were modeled using reinforcement learning algorithms. ADHD participants made more exploratory decisions (i.e., chose options without the highest expected reward value) and earned fewer points than controls in all three study days, and methylphenidate did not affect these outcomes. Baseline exploratory choices were positively associated with hyperactive ADHD symptoms across all participants. These results support several theoretical models of increased exploratory choices in ADHD and suggest the unexplained variance in ADHD decisions may be due to less value tracking. The inability to suppress actions with little to no reward value may be a key feature of hyperactive ADHD symptoms.

BACKGROUND: A reduced willingness to perform effort based on the magnitude and probability of potential rewards has been associated with diminished dopamine function and may be relevant to attention-deficit/hyperactivity disorder (ADHD). Here, we investigated the influence of ADHD status and methylphenidate on effort-based decisions. We hypothesized that ADHD participants would make fewer high-effort selections than non-ADHD subjects, and that methylphenidate would increase the number of high-effort selections. Furthermore, we hypothesized there would be associations among ADHD severity and methylphenidate-related changes in effort-based and attentional performance across all participants. METHODS AND PARTICIPANTS: ADHD (nâ¯=â¯23) and non-ADHD (nâ¯=â¯23) adults completed the Effort Expenditure for Rewards Task in which participants select between low-effort and high-effort options to receive monetary rewards at varying levels of reward magnitude and probability. A test of attentional performance was also completed. RESULTS: Overall, participants made more high-effort selections as potential reward magnitude and probability increased. ADHD participants did not make fewer high-effort selections than non-ADHD participants, but ADHD participants showed greater methylphenidate-related increases in high-effort selections. ADHD participants had worse attentional performance than non-ADHD participants. ADHD severity was associated with methylphenidate-related changes in high-effort selections, but not changes in attentional performance. CONCLUSIONS: These results indicate that methylphenidate increases the willingness to perform effort in individuals with ADHD, possibly due to disorder-related motivational deficits. This provides support for theories of insufficient effort allocation among individuals with ADHD. TRIAL REGISTRATION: Clinicaltrials.gov Identifier, NCT02630017.

Pediatric obsessive-compulsive disorder (OCD) can be effectively treated with family-based intervention by expanding and enhancing family members' behavioral repertoire to more effectively manage OCD symptoms and affected family interactions. This article provides an overview and practical understanding of the implementation of family-based treatment of pediatric OCD. Special attention is given to relevant contextual family processes that influence symptom presentation, current empirical support for family-based treatment, and the clinical application of family-based cognitive-behavioral therapy. Case vignettes illustrate important clinical considerations for providers.

Pediatric obsessive-compulsive disorder (OCD) is associated with substantial morbidity, comorbidity, family difficulties, and functional impairment. Fortunately, OCD in youth has also been found responsive to cognitive behavioral therapy (CBT) both alone and in combination with medication. This paper highlights key areas a treatment provider must be highly knowledgeable in to be considered an expert in cognitive behavioral therapy (CBT) for pediatric obsessive-compulsive disorder (OCD). We describe the areas of knowledge that must be mastered to gain expertise, as well as the more difficult to quantify personal qualities that may allow a clinician to convey this knowledge in an expert manner. We provide detailed discussions of CBT theory, assessment strategies, implications of the treatment outcome literature for clinical decision-making, and how best to navigate CBT. We also discuss what the expert needs to accomplish by engaging youth and families throughout the evaluation and treatment process.

OBJECTIVE: To identify predictors and moderators of outcome in the first Pediatric OCD Treatment Study (POTS I) among youth (N = 112) randomly assigned to sertraline, cognitive behavioral therapy (CBT), both sertraline and CBT (COMB), or a pill placebo. METHOD: Potential baseline predictors and moderators were identified by literature review. The outcome measure was an adjusted week 12 predicted score for the Children's Yale Brown Obsessive Compulsive Scale (CY-BOCS). Main and interactive effects of treatment condition and each candidate predictor or moderator variable were examined using a general linear model on the adjusted predicted week 12 CY-BOCS scores. RESULTS: Youth with lower obsessive-compulsive disorder (OCD) severity, less OCD-related functional impairment, greater insight, fewer comorbid externalizing symptoms, and lower levels of family accommodation showed greater improvement across treatment conditions than their counterparts after acute POTS treatment. Those with a family history of OCD had more than a sixfold decrease in effect size in CBT monotherapy relative to their counterparts in CBT without a family history of OCD. CONCLUSIONS: Greater attention is needed to build optimized intervention strategies for more complex youth with OCD. Youth with a family history of OCD are not likely to benefit from CBT unless offered in combination with an SSRI.

UNLABELLED: This paper presents the rationale, design, and methods of the Pediatric Obsessive-Compulsive Disorder Treatment Study II (POTS II), which investigates two different cognitive-behavior therapy (CBT) augmentation approaches in children and adolescents who have experienced a partial response to pharmacotherapy with a serotonin reuptake inhibitor for OCD. The two CBT approaches test a "single doctor" versus "dual doctor" model of service delivery. A specific goal was to develop and test an easily disseminated protocol whereby child psychiatrists would provide instructions in core CBT procedures recommended for pediatric OCD (e.g., hierarchy development, in vivo exposure homework) during routine medical management of OCD (I-CBT). The conventional "dual doctor" CBT protocol consists of 14 visits over 12 weeks involving: (1) psychoeducation, (2), cognitive training, (3) mapping OCD, and (4) exposure with response prevention (EX/RP). I-CBT is a 7-session version of CBT that does not include imaginal exposure or therapist-assisted EX/RP. In this study, we compared 12 weeks of medication management (MM) provided by a study psychiatrist (MM only) with two types of CBT augmentation: (1) the dual doctor model (MM+CBT); and (2) the single doctor model (MM+I-CBT). The design balanced elements of an efficacy study (e.g., random assignment, independent ratings) with effectiveness research aims (e.g., differences in specific SRI medications, dosages, treatment providers). The study is wrapping up recruitment of 140 youth ages 7-17 with a primary diagnosis of OCD. Independent evaluators (IEs) rated participants at weeks 0,4,8, and 12 during acute treatment and at 3,6, and 12 month follow-up visits. TRIAL REGISTRATION: NCT00074815.
ABSTRACT
Obsessive-compulsive disorder (OCD) is a distressing and functionally impairing disorder that can emerge as early as age 4. Cognitive behavior therapy (CBT) for OCD in youth shows great promise for amelioration of symptoms and associated functional impairment. However, the empirical evidence base for the efficacy of CBT in youth has some significant limitations, particularly as related to treating the very young child with OCD. This report includes a quantitative review of existing child CBT studies to evaluate evidence for the efficacy of CBT for OCD. It identifies gaps in the literature that, when addressed, would enhance the understanding of effective treatment in pediatric OCD. Finally, it presents a proposed research agenda for addressing the unique concerns of the young child with OCD.
