OBJECTIVE: To determine the long-term durability of behavior therapy for tics among youth with Tourette disorder and persistent (chronic) motor or vocal tic disorders. METHOD: Of the 126 youth who participated in a randomized controlled trial of behavior therapy 11 years prior, 80 were recruited for this longitudinal follow-up. Consenting participants were interviewed in person or remotely (Web-based video) by trained evaluators to determine the course of tics, current tic severity, and tic-related impairment...

OBJECTIVE: The Action for Health in Diabetes (Look AHEAD) study previously reported that intensive lifestyle intervention (ILI) reduced incident depressive symptoms and improved health-related quality of life (HRQOL) over nearly 10 years of intervention compared with a control group (the diabetes support and education group [DSE]) in participants with type 2 diabetes and overweight or obesity. The present study compared incident depressive symptoms and changes in HRQOL in these groups for an additional 6 years following termination of the ILI in September 2012...

INTRODUCTION: Violence risk assessment is one of the most frequent reasons for child and adolescent psychiatry consultation with adolescents in the pediatric emergency department (ED). Here we provide a systematic review of risk factors for violence in adolescents using the risk factor categories from the MacArthur Violence Risk Assessment study. Further, we provide clinical guidance for assessing adolescent violence risk in the pediatric ED. METHODS: For this systematic review, we used the preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2009 checklist...

The use of an oral orthotic, called an occlusal splint, has gained recognition for the potential to reduce the frequency of tics for individuals with Persistent Tic Disorders. The purpose of this study was to assess the feasibility of a fully blinded, randomized controlled trial (RCT) to assess the safety, tolerability and initial efficacy of the oral orthotic in youth with chronic tics. Thirteen youth were randomly assigned to wear an active or sham orthotic in a two week double-blind RCT, with a 4-6 week unblinded follow up period...

Objective: To identify predictors of medication-placebo differences in double-blind placebo-controlled antidepressant trials in children and adolescents with anxiety and depression. Methods: Clinical trials in patients <18 years of age with major depressive disorder or generalized, separation or social anxiety disorders were obtained from PubMed, the Cochrane Database and clinicaltrials.gov searches from inception through 2019. Forty-nine trials (43 published and 6 unpublished) of anxiety ( κ  = 13) and depression ( κ  = 36) evaluated 19 antidepressants in 8642 child and adolescent patients; placebo and medication response rates, trial characteristics, disorder, medication class, and funding source were extracted...

Behavior therapy is a first-line intervention for Tourette's Disorder (TD), and a key component is the practice of therapeutic skills between treatment visits (i.e., homework). This study examined the relationship between homework adherence during behavior therapy for TD and therapeutic outcomes, and explored baseline predictors of homework adherence during treatment. Participants included 119 individuals with TD (70 youth, 49 adults) who received behavior therapy in a clinical trial. After a baseline assessment of tic severity and clinical characteristics, participants received 8 sessions of behavior therapy...

Normal developmental activities (eg, going to school, raising a hand in class, and managing typical life uncertainties) are 'triggers' for children and adolescents with anxiety disorders. To cope, children with anxiety avoid; however, when avoidance of developmentally appropriate activities is not possible, catastrophic responses can ensue. If these catastrophic reactions result in successful avoidance, they are likely to recur leading to a generalized pattern of dysregulated behavior. Interventions include treating anxiety disorder symptoms to remission...

OBJECTIVE: Moderate- to vigorous-intensity physical activity (MVPA) improves cardiovascular health. Few studies have examined MVPA timing. We examined the associations of timing of bout-related MVPA with cardiorespiratory fitness and cardiovascular risk in adults with type 2 diabetes. RESEARCH DESIGN AND METHODS: Baseline 7-day hip-worn accelerometry data from Look AHEAD participants ( n = 2,153, 57% women) were analyzed to identify bout-related MVPA (≥3 METs/min for ≥10 min)...

This study describes impairment in academic, interpersonal, recreational, and family financial or occupational domains across children in three mutually exclusive diagnostic groups: ever diagnosed with Tourette syndrome (TS), attention-deficit/hyperactivity disorder (ADHD), and both disorders. In 2014, parents reported on impairment and diagnostic status of children aged 4-17 years (n = 3014). Weighted analysis and pairwise t-tests showed more children with ADHD (with or without TS) experienced impairment in overall school performance, writing, and mathematics, relative to children with TS but not ADHD...

OBJECTIVE: Treatment guidelines for Tourette's Disorder (TD) are based on patients' degree of tic severity and impairment. However, clear benchmarks for determining tic severity and impairment have not been established. This study examined benchmarks of tic severity and tic impairment using the Yale Global Tic Severity Scale (YGTSS) and the Clinical Global Impression of Severity (CGI-S). METHOD: Individuals with TD or another Tic Disorder (N = 519) recruited across nine sites were administered a diagnostic interview, the YGTSS, and the CGI-S...

OBJECTIVE: (1) To describe rates of long-term service use among subjects previously enrolled in a landmark study of youth anxiety disorder treatment and followed into early adulthood; (2) to examine predictors of long-term service use; and (3) to examine the relationship between anxiety diagnosis and service use over time. METHOD: The Child/Adolescent Anxiety Multimodal Extended Long-term Study prospectively assessed youths treated through the Child/Adolescent Anxiety Multimodal Study at ages 7-17 years into early adulthood...

BACKGROUND: To examine the relationship between early physical activity (PA) adoption (2, 3, and 4 mo) and longer-term PA adherence (1 y) among individuals who were inactive at baseline and received a lifestyle intervention. METHODS: Participants (n = 637) received weekly behavioral weight loss sessions, calorie reduction, and PA goals (50-175 min/wk progression). PA was assessed via self-reported measures at baseline, months 2 to 4, and 1 year. RESULTS: PA at months 2 to 4 was significantly correlated with PA at 1 year (rs = ...

Treatment of pediatric anxiety disorders is complicated by their number, comorbidity, and the differential impact of a child's anxiety on the child and parents. Measurement-based care, using patient-level rating scales, can guide clinical decisions, track symptom improvement, and monitor treatment response. We review instruments for measurement-based care in pediatric anxiety. Measures used to track pediatric anxiety should be brief, accessible, sensitive to change, and reliable. Because parent-child agreement about a child's anxiety tends to be low, measures from both should be obtained...

Treatment of Tourette syndrome (TS) can be complicated by changes over time in tic expression, severity, and co-occurring disorders. Using the 2014 National Survey of the Diagnosis and Treatment of ADHD and Tourette Syndrome, this study provides descriptive estimates of the use of behavioral interventions and medication among children living with TS. Parent-reported data on 115 children aged 5-17 years ever diagnosed with TS were analyzed to provide descriptive, unweighted results. Overall, 77.4% of children had current or past use of any TS treatment; 59...

The Comprehensive Behavioral Intervention for Tic Disorders (CBIT) has demonstrated efficacy in large randomized controlled trials for children (≥9 yrs), adolescents and adults with Tourette Syndrome and Chronic Tic Disorders. Given the early age of onset for tic disorders, a large portion of affected individuals with chronic tic disorders are less than 9 years of age and appropriate developmental adaptations of behavioral treatment have not yet been tested. The goal of this study was to adapt and evaluate the acceptability and utility of a family-based adaptation of CBIT for children under 9 years of age...
