RESUMO
This study combines data from five studies in a quantitative modeling approach to improve identification of tics and tic disorders using two questionnaires (the Motor or Vocal Inventory of Tics and the Description of Tic Symptoms), administered to parents and children N = 1 , 307 . Combining final diagnoses (positive or negative for tic disorder) with data from recently developed questionnaires implemented to assist in the identification of tics and tic disorders in children, we investigate methods for predicting positive diagnosis while also identifying which items in the questionnaires are most predictive. Logistic regression and random forest models are compared using various summary statistics. We further discuss the differences in errors (false positives versus false negatives) in the specification of predictive model tuning parameters. Compared to logistic regression models, random forest models provided comparable and often superior predictive abilities and were also more useful in summarizing the contributions to predictions from individual questions. The combined analyses identified a subset of screener questions that were the best predictors of tic disorders; the identified questions differed based on parent or self-report. These results provide information to inform the future development of tools to screen for tics in a variety of healthcare and epidemiological settings.
RESUMO
OBJECTIVE: Misophonia is a psychiatric condition characterized by strong emotional and/or behavioral responses to auditory stimuli, leading to distress and functional impairment. Despite previous attempts to define and categorize this condition, misophonia is not currently included in the Diagnostic and Statistical Manual of Mental Disorders or International Classification of Diseases. The lack of formal diagnostic consensus presents challenges for research aimed at assessing and treating this clinical presentation. METHODS: The current study presents clinical characteristics of youth (N = 47) with misophonia in the largest treatment-seeking sample to date. We examined demographic characteristics of the sample, frequency of comorbid disorders, frequency of specific misophonia symptoms (i.e., triggers, emotional and behavioral responses, and impairments), and caregiver-child symptom agreement. Misophonia symptoms were evaluated using a multimodal assessment including clinician, youth, and caregiver reports on empirically established misophonia measures, and concordance among measures was assessed. RESULTS: Youth seeking treatment for misophonia presented with marked misophonia symptoms and an array of comorbid conditions. Youth and caregivers identified various triggers of misophonia symptoms (e.g., chewing sounds, breathing sounds), as well as a wide range of emotional (e.g., anger, annoyance, disgust) and behavioral (e.g., aggression, avoidance) responses to triggers. Youth and caregivers exhibited high agreement on misophonia triggers but lower agreement on symptom severity and associated impairment. Compared to younger children (aged 8-13), older children (aged 14+) appeared to report symptom severity and associated impairment more reliably. CONCLUSION: Misophonia is a heterogenous and impairing clinical condition that warrants future investigation and evidence-based treatment development.

Tics are unwanted, repetitive movements and sounds that frequently present during childhood. They are typically brief and purposeless, but can create significant distress for individuals, and often co-occur with other neuropsychiatric conditions. Thus, early identification of tics is warranted. Unfortunately, tics are often misdiagnosed, and because tics may wax and wane, identification can be difficult, especially in the context of routine clinical visits. There are limited tools that can be used to reliably identify tics in clinical practice, especially in non-specialty settings. The purpose of the current study was to evaluate the performance of the Motor tic, Obsession and compulsion, and Vocal tic Evaluation Survey (MOVES), a self-report scale with some support as a screening tool. In addition, the performance of a subset of questions (the MOVES-6) was evaluated for rapid screening. Participants were recruited across two study sites and included children and adolescents diagnosed with Tourette syndrome (n = 151) or another persistent tic disorder (n = 10) and community controls (n = 74). Results suggest both the MOVES and the MOVES-6 have high sensitivity (90% and 88%, respectively) and at least acceptable specificity (77% and 86%, respectively) compared with expert assessment of tic disorders, suggesting that both versions can identify tic disorders without high proportions of false negatives. Both versions were highly sensitive with acceptable specificity regardless of sex, race/ethnicity, and age. The MOVES and MOVES-6 show promise as a screener for tics or tic disorders, but additional research is needed, particularly in a general population setting.
RESUMO
BACKGROUND: Tourette syndrome (TS) is associated with learning disabilities and educational impairment. Teacher knowledge about TS may have a positive impact on students with TS, but factors associated with teacher knowledge of TS are not known. METHODS: In this cross-sectional study, teachers of youth with TS and of a community control group completed a Teacher Understanding of Tourette Syndrome Survey (TUTS), a pilot questionnaire enquiring about self-perceived understanding, teacher knowledge, and sources of information. We compared TUTS scores between TS and control groups and between those who did and did not use specific sources of information about TS using Wilcoxon rank-sum tests. Bivariate correlation analyses were used to evaluate associations between teacher knowledge and potential contributing factors. RESULTS: Data from 114 teachers of children with TS and 78 teachers of control subjects were included. Teachers of youth with TS had significantly more knowledge, had higher self-perceived understanding, and used more sources of information than teachers of the control group. Teachers who knew of the Tourette Association of America and who gathered information themselves had higher knowledge about TS than those who did not. CONCLUSION: Teachers of children with TS know more about TS and use more sources to learn about TS than teachers of children without TS.

BACKGROUND: There is little information on the clinical presentation, functional impact, and psychiatric characteristics of misophonia in youth, an increasingly recognized syndrome characterized by high emotional reactivity to certain sounds and associated visual stimuli. METHOD: One-hundred-two youth (8-17 years-old) with misophonia and their parents were recruited and compared with 94 youth with anxiety disorders. Participants completed validated assessments of misophonia severity, quality of life, as well as psychiatric symptoms and diagnoses. RESULTS: The most common misophonia triggers included eating (96 %), breathing (84 %), throat sounds (66 %), and tapping (54 %). Annoyance/irritation, verbal aggression, avoidance behavior, and family impact were nearly universal. Misophonia severity was associated with internalizing symptoms, child-reported externalizing behaviors, and poorer quality of life. High rates of comorbidity with internalizing and neurodevelopmental disorders were found. Quality of life and externalizing behaviors were not significantly different between misophonia and anxiety samples; internalizing symptoms and autism characteristics were significantly higher among youth with anxiety disorders. LIMITATIONS: This self-selected sample was characterized by limited multicultural diversity. CONCLUSIONS: This study presents misophonia as a highly impairing psychiatric syndrome. Future interdisciplinary work should clarify the mechanisms of misophonia, establish evidence-based treatments, and extend these findings to randomly sampled and more culturally diverse populations.

Versions of cognitive behavioral therapy (Coping Cat, CC; Behavioral Interventions for Anxiety in Children with Autism, BIACA) have shown efficacy in treating anxiety among youth with autism spectrum disorder. Measures of efficacy have been primarily nomothetic symptom severity assessments. The current study examined idiographic coping outcomes in the Treatment of Anxiety in Autism Spectrum Disorder study (N = 167). Longitudinal changes in coping with situations individualized to youth fears (Coping Questionnaire) were examined across CC, BIACA and treatment as usual (TAU) in a series of multilevel models. CC and BIACA produced significantly greater improvements than TAU in caregiver-reported coping. Youth report did not reflect significant differences. Results show the efficacy of CC and BIACA in improving idiographic caregiver-, but not youth-, reported youth coping.

Objective: Accommodation, or the ways in which families modify their routines and expectations in response to a child's anxiety, is common and interferes with anxiety treatment outcomes. However, little research has examined family accommodation among youth with autism spectrum disorder and anxiety. The current study aimed to (a) identify pre-treatment correlates of accommodation, (b) examine changes in accommodation after treatment, and (c) assess relationships between accommodation and post-treatment anxiety severity.Method: The sample consisted of 167 youth (mean age = 9.90 years; 79.6% male; 18% Latinx) with clinically significant anxiety and a diagnosis of autism spectrum disorder who were enrolled in a randomized clinical trial comparing two cognitive behavioral therapy interventions for anxiety and treatment-as-usual. Participants were evaluated for symptom severity and family accommodation at pre- and post-treatment.Results: Results indicated that clinician-rated anxiety severity and parent-rated externalizing behaviors and autism spectrum disorder severity significantly predicted pre-treatment accommodation. Accommodation significantly decreased from pre- to post-treatment and non-responders showed significantly higher accommodation at post-treatment compared to responders. Finally, youth with higher pre-treatment accommodation had higher post-treatment anxiety.Conclusions: Findings indicate that accommodation for anxiety is common among youth with autism spectrum disorder and anxiety. Furthermore, accommodation is implicated in treatment outcomes and should be targeted in treatment for youth with autism spectrum disorder and anxiety.

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.

Consistent with international reports,1 this group of Tourette syndrome (TS) experts has noticed a recent increase in adolescents presenting with tic-like symptoms that show a markedly atypical onset and course. These sudden-onset motor movements and vocalizations are often associated with significant impairment and disability, resulting in emergency department visits and hospitalizations for some affected youths.

BACKGROUND: Misophonia is a condition marked by dysregulated emotions and behaviors in response to trigger sounds, often chewing, breathing, or coughing. Evidence suggests that misophonia develops in adolescence and the emotions and behaviors are a conditioned response to distress, resulting in social avoidance, stress, and family conflict. In addition, co-occurrence with other psychiatric illnesses such as anxiety, OCD, and Tourette syndrome is common. A transdiagnostic cognitive behavioral therapeutic (CBT) approach appears appropriate. There are currently no controlled studies of youth with misophonia. The current paper describes the approach to a pilot randomized, blinded family-based treatment study for youth ages 8-16 years. Preliminary results from a pilot open trial also are described. METHODS: A 2-phase dual site telehealth treatment study using a transdiagnostic CBT approach, the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Children and Adolescents (UP-C/A; Ehrenreich-May et al., 2018), is proposed. Phase 1 consisted of a 4-case pilot of UP-C/A. Phase 2 includes a randomized trial comparing the UP-C/A to a standard relaxation and education protocol. RESULTS: Preliminary results from the pilot show modest improvements in evaluator-rated misophonia symptoms on the Clinical Global Impression Severity and Improvement scales. LIMITATIONS: There is little research to inform evidence-based practice for youth with misophonia. Study limitations include lack of standardized misophonia assessment instruments and an absence of formal diagnostic criteria. CONCLUSIONS: The current paper describes proposed methods for the first randomized controlled trial for youth with misophonia and their families along with results from a 4-case pilot.

BACKGROUND: Compulsive buying (CB) is characterized by intrusive thoughts and behaviors related to the purchase of items, whereas obsessive-compulsive disorder (OCD) seems to arise from misattributed anxiety to a neutral stimulus resulting in the avoidance of the feared stimuli. Examining the triggers for the behaviors may provide useful information to possible shared etiology. METHODS: A total of 528 participants (age: mean = 20.97, SD = 5.15 years) were recruited through an online volunteer pool at a large university. Each participant completed demographic and clinical measures as well as the Behavioral Inhibition and Activation Sensitivities (BIS/BAS) self-report questionnaire. RESULTS: The OCD group (n = 101) endorsed the highest scores on BAS Reward Responsivity, which were statistically comparable to the control (n = 365) and CB groups (n = 27), yet significantly higher than the CB/OCD group (n = 35) (P < .007). The CB group did not differ from any group with regard to the BAS. The OCD group scored significantly higher than controls (P < .001), but did not differ significantly from the CB group (P = .05) on the BIS. CONCLUSIONS: OCD and CB/OCD endorsed the highest sensitivity to threat and motivation to reduce distress. Together, these results convey anxiety and motivation to reduce distress as factors that differentiate groups and likely motivation to engage in compulsive behaviors.

Individuals with Tourette's Disorder and Persistent Tic Disorders (TD) often experience premonitory urges-aversive sensations that precede tics and are relieved by tic expression. Given its role in the neurobehavioral model of TD, understanding factors that influence premonitory urges and associated relief can advance understanding of urge phenomenology and optimize treatments for individuals with TD. This study examined whether the novel construct of urge intolerance-difficulty tolerating premonitory urges-predicted tic severity and tic-related disability. Participants included 75 youth with TD and their caregivers. Assessments characterized tic severity, premonitory urge, distress tolerance, internalizing symptoms, and tic-related disability. Structural equation modeling revealed that higher levels of urge intolerance predicted greater levels of tic-related disability. Furthermore, the relationship between urge intolerance and tic-related disability was more robust for youth with clinically-elevated levels of internalizing symptoms. While further investigation is needed, urge intolerance represents a promising treatment target to improve tic-related disability in youth with TD.

We compared anxiety symptoms in youth with and without tic disorders by comparing scores on the Multidimensional Anxiety Scale for Children (MASC) in youth with tic disorders to those in a concurrent community control group and in a group of treatment-seeking anxious youth from the Child/Adolescent Anxiety Multimodal Study (CAMS). Data from 176 youth with tic disorders, 93 control subjects, and 488 CAMS participants were included. Compared to youth with tic disorders, controls had lower total MASC scores (p < 0.0001) and CAMS participants had similar total MASC scores (p = 0.13). Separation Anxiety (p = 0.0003) and Physical Symptom (p < 0.0001) subscale scores were higher in youth with tic disorders than in CAMS participants. We conclude that the anxiety symptom profile differs in youth with and without tic disorders, which may have important implications for targeting treatment of anxiety in youth with tic disorders.

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. Correlations and trend analyses contrasted YGTSS scores across CGI-S ratings. A logistic regression model examined predictive benchmarks for tic severity, tic impairment, and global severity. Model classifications were compared against CGI-S ratings, and agreement was examined using kappa. RESULTS: Spearman correlations between the CGI-S and YGTSS scores ranged from 0.54 to 0.63 (p < 0.001). Greater CGI-S ratings were associated with a linear stepwise increase in YGTSS Total Tic scores, Impairment scores, and Global Severity scores. Despite moderate-to-strong associations (ρ = 0.45-0.56, p < 0.001) between the CGI-S and predictive logistical regression models, only fair agreement was achieved when applying classification benchmarks (κ = 0.21-0.32, p < 0.001). CONCLUSIONS: CGI-S ratings are useful to characterize benchmarks for tic severity, tic impairment, and global severity on the YGTSS. Logistic regression model benchmarks had only fair agreement with the CGI-S and underscore the heterogeneity of TD symptoms. Collectively, findings offer guidance on the delineation of tic severity categorizations to apply evidence-based treatment recommendations.

This report investigated the improvement in Automatic and Focused styles of hair pulling among youth with trichotillomania (TTM). Youth with TTM (N = 40) participated in a clinical trial that compared habit reversal training (HRT) to treatment-as-usual (TAU). Participants completed a baseline assessment to characterize hair pulling severity, self-reported hair pulling styles, and co-occurring psychiatric conditions. Youth were randomly assigned to receive eight weekly sessions of HRT or eight weeks of TAU. Afterward, youth completed a post-treatment assessment of hair pulling severity and hair pulling styles. Youth in the TAU condition then received eight weekly sessions of HRT and completed another post-treatment assessment. Analyses revealed that the Focused pulling style largely improved with HRT (d = 0.73) compared to TAU (d = 0.11). However, there was limited improvement for the Automatic pulling style following either HRT (d = 0.10) or TAU (d = -0.31). This same pattern of effects was also found during open-label treatment with HRT. Although behavior therapies such as HRT are the principle treatment for youth with TTM, the Automatic pulling style exhibited limited improvement to this therapeutic approach. Therefore, therapeutic strategies that enhance awareness to pulling behaviors may produce more robust outcomes to behavior therapy for youth with TTM.

Children with Tourette syndrome often have behavioral and social difficulties, which may be associated with co-occurring mental, emotional, or behavioral disorders. This study investigated social competence, including behavioral problems and social skills, and social activities between children with and without Tourette syndrome using a nationally representative sample. In the 2007 National Survey of Children's Health, parents reported on health care provider diagnosis of Tourette syndrome, co-occurring mental, emotional, or behavioral disorders, and indicators of social competence. Children aged 6-17 years with and without Tourette syndrome were compared. Most (78.7%) children with Tourette syndrome had a co-occurring mental, emotional, or behavioral disorder. Children with Tourette syndrome had significantly lower social competence, exhibited by higher levels of behavior problems (mean score 11.6 for Tourette syndrome and 9.0 for no Tourette syndrome) and lower levels of social skills (mean 15.3) than children without a Tourette syndrome diagnosis (mean 17.1); however, these associations were no longer significant after controlling for co-occurring mental, emotional, or behavioral disorders. Moderate to severe Tourette syndrome was associated with the highest ratings of behavioral problems and the lowest ratings of social skills. Children with and without Tourette syndrome were equally likely to participate in social activities; the difference for children with moderate to severe Tourette syndrome being less likely to participate in activities compared to children with mild Tourette syndrome had a chi-square test P value of .05. In conclusion, Tourette syndrome was associated with lower social competence, particularly for children with moderate to severe Tourette syndrome. Monitoring social functioning and co-occurring conditions among children with Tourette syndrome, and referral for evidence-based interventions when needed, may benefit overall health and functioning.

The impact of externalizing comorbidity on treatment outcome was examined in 104 youth ages 7-16 (M = 11.09 years) with autism spectrum disorder and primary anxiety/obsessive compulsive disorder who completed modular cognitive behavioral therapy (CBT) for anxiety/OCD. Three comorbidity profiles were utilized for group comparisons: participants with oppositional defiant or conduct disorder with attention-deficit hyperactivity disorder (ODD; CD; ADHD; group EXT, n = 25); those without ODD/CD and only ADHD (group ADHD, n = 46); and those without externalizing comorbidity (NO-EXT, n = 33). Post-treatment outcomes were measured continuously (Pediatric Anxiety Rating Scale, Clinical Global Impression-Severity) and categorically (treatment response, remission). The ADHD group was four times more likely of being a treatment responder compared to NO-EXT (OR 4.05). Comorbidity group did not impact remission. After controlling for pre-treatment scores, there was a significantly greater reduction of the CGI-S for ADHD versus NO-EXT and EXT versus NO-EXT, but results did not significantly differ for the PARS. Results suggest that a modular CBT approach yields positive impact for treatment outcomes in youth with comorbid externalizing problems, particularly among those with comorbid ADHD.

OBJECTIVE: Chronic tic disorders occur in approximately 3% of children. Neuropsychiatric symptoms of attention-deficit/hyperactivity disorder, obsessive-compulsive disorder, anxiety, and depression are common. We evaluated the impact of tic disorders and comorbid symptoms on individual and parent quality of life and family functioning. METHOD: In two cross-sectional studies children with tic disorders were enrolled at the University of Rochester or the University of South Florida; data were pooled for analyses. Control subjects were enrolled at the University of Rochester. We compared quality of life and function in youth and families with and without tic disorders. We evaluated the associations between comorbid symptoms and individual quality of life and family impact in youth with tic disorders using multiple regression analyses. RESULTS: We enrolled 205 youths with tic disorders and 100 control subjects. Psychosocial (P < 0.0001) and physical (P < 0.0001) quality of life were lower in individuals with tic disorders compared with controls. Severity of attention-deficit/hyperactivity disorder (P < 0.0001) and depression (P = 0.046) symptoms were associated with lower psychosocial quality of life in youth with tic disorders. Families of youths with tic disorders had worse parent quality of life (P < 0.001) and family functioning (P < 0.001) than control families. Severity of attention-deficit/hyperactivity disorder (P < 0.0001), obsessive-compulsive disorder (P = 0.0004), and depression (P = 0.01) symptoms were associated with predicted worse family impact. CONCLUSION: Youths with tic disorders had lower individual and parent quality of life and worse family functioning than controls. The impact of tic disorders on the family may have significant implications for approaches to providing comprehensive care to these families.

Objectives: In clinical trials of pediatric trichotillomania (TTM), three instruments are typically employed to rate TTM severity: (1) the Massachusetts General Hospital Hair Pulling Scale (MGH-HPS), (2) the National Institute of Mental Health Trichotillomania Severity Scale (NIMH-TSS), and (3) the Trichotillomania Scale for Children (TSC). These instruments lack standardized definitions of treatment response, which lead researchers to determine their own definitions of response post hoc and potentially inflate results. We performed a meta-analysis to provide empirically determined accuracy measures for percentage reduction cut points in these three instruments. Methods: MEDLINE was searched for TTM clinical trials. A total of 67 studies were initially identified, but only 5 were clinical trials focused on TTM in pediatric populations and therefore were included in this meta-analysis (n = 180). A Clinical Global Impressions Improvement score ≤2 was used to define clinical response. Receiver operating characteristic principles were employed to determine accuracy measures for percentage reduction cut points on each one of the instruments. Meta-DiSc software was employed to provide pooled accuracy measures for each cut point for each instrument. The Youden Index and the distance to corner methods were used to determine the optimal cut point. Results: The optimal cut points to determine treatment response were a 45% reduction on the MGH-HPS (Youden Index 0.40, distance to corner 0.20), a 35% reduction on the NIMH-TSS (Youden Index 0.42, distance to corner 0.17), a 25% reduction on the TSC child version (TSC-C; Youden Index 0.40, distance to corner 0.18), and a 45% (distance to corner 0.30) or 50% reduction (Youden Index 0.33) on the TSC parent version (TSC-P). The TSC-C had less discriminative ability at determining response in younger children in comparison to older children; no age-related differences were observed on the TSC-P. Conclusions: This study provides empirically determined cut points of treatment response on three instruments that rate TTM severity. These data-driven cut points will benefit future research on pediatric TTM.
