Abstract
Objectives: Pediatric acute-onset neuropsychiatric syndrome (PANS) is characterized by sudden onset of obsessive-compulsive disorder and/or eating restriction with associated neuropsychiatric symptoms from at least two of seven categories. The PANS 31-Item Symptom Rating Scale (PANS Rating Scale) was developed to identify and measure the severity of PANS symptoms. The objective of this study was to define the psychometric properties of the PANS Rating Scale. Methods: Children with PANS (N = 135) and their parents participated. Parents completed the PANS Rating Scale and other scales on Research Electronic Data Capture. The PANS Rating Scale includes 31 items that are rated on a Likert scale from 0 = none to 4 = extreme. Pearson's correlations were run between the PANS Total score and scores on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS), Yale Global Tic Severity Scale (YGTSS), Modified Overt Aggression Scale (MOAS), Columbia Impairment Scale (CIS), PANS Global Impairment Score (GIS), and Children's Global Assessment Scale (CGAS). Results: Convergent validity was supported by significant correlations between the PANS Total and scores on the CY-BOCS, YGTSS, MOAS, CIS, GIS, and CGAS. The largest correlations were with measures of functional impairment: PANS Total and CIS (r = 0.81) and PANS Total and GIS (r = 0.74). Cronbach's alpha was 0.89 which demonstrates strong internal consistency of the 31 items. PANS Total score was significantly higher in children in a flare of their neuropsychiatric symptoms compared to children who were not in a flare. Conclusions: This study provides preliminary support for the PANS Rating Scale as a valid research instrument with good internal consistency. The PANS Rating Scale appears to be a useful measure for assessing children with PANS.

Teacher Knowledge of Tourette Syndrome and Associated Factors. Pediatr Neurol 2023; 145:80-87. [PMID: 37295059 DOI: 10.1016/j.pediatrneurol.2023.05.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 05/03/2023] [Accepted: 05/10/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND 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.

Brief youth self-report screener for tics: Can a subscale of the Motor tic, Obsession and compulsion, and Vocal tic Evaluation Survey (MOVES) identify tic disorders in youth? EVIDENCE-BASED PRACTICE IN CHILD AND ADOLESCENT MENTAL HEALTH 2023; 8:1-11. [PMID: 37323827 PMCID: PMC10267813 DOI: 10.1080/23794925.2023.2191354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/17/2023]
Abstract
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.

Cognitive Beliefs Across the Symptom Dimensions of Pediatric Obsessive-Compulsive Disorder: Type of Symptom Matters. Behav Ther 2022; 53:240-254. [PMID: 35227401 PMCID: PMC9397538 DOI: 10.1016/j.beth.2021.08.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 08/06/2021] [Accepted: 08/12/2021] [Indexed: 02/03/2023]
Abstract
The cognitive model of obsessive-compulsive disorder (OCD) posits that dysfunctional cognitive beliefs are crucial to the onset and maintenance of OCD; however, the relationship between these cognitive beliefs and the heterogeneity of OCD symptoms in children and adolescents remains unknown. We examined how the major belief domains of the cognitive model (inflated responsibility/threat estimation, perfectionism/intolerance of uncertainty, importance/control of thoughts) and dysfunctional metacognitions were related to OCD symptoms across the following dimensions: doubting/checking, obsessing, hoarding, washing, ordering, and neutralization. Self-report ratings from 137 treatment-seeking youth with OCD were analyzed. When cognitive beliefs and symptom dimensions were analyzed in tandem, inflated responsibility/threat estimation and dysfunctional metacognitions were uniquely related to doubting/checking, obsessing, and hoarding and perfectionism/intolerance of uncertainty to ordering. Cognitive beliefs explained a large proportion of variation in doubting/checking (61%) and obsessing (46%), but much less so in ordering (15%), hoarding (14%), neutralization (8%), and washing (3%). Similar relations between cognitive beliefs and symptom dimensions were present in children and adolescents. Cognitive beliefs appear to be relevant for pediatric OCD related to harm, responsibility, and checking, but they do not map clearly onto contamination and symmetry-related symptoms. Implications for OCD etiology and treatment are discussed.

Urge Intolerance and Impairment Among Youth with Tourette's and Chronic Tic Disorders. Child Psychiatry Hum Dev 2021; 52:761-771.

Abstract
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.

Irritability in Children and Adolescents With OCD. Behav Ther 2021; 52:883-896. [PMID: 34134828 PMCID: PMC8217718 DOI: 10.1016/j.beth.2020.11.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 09/30/2020] [Accepted: 11/01/2020] [Indexed: 01/22/2023]
Abstract
Irritability is a common, impairing transdiagnostic symptom in childhood psychopathology, though it has not been comprehensively studied in pediatric obsessive-compulsive disorder (OCD). Further, the central cognitive behavioral treatment component for OCD, exposure and response prevention therapy (ERP), has been recently proposed as a treatment for irritability. This study aimed to evaluate whether certain clinical characteristics are associated with irritability in pediatric OCD and whether irritability reduces following ERP. Participants were 161 youth (ages 7-17) with OCD and a caregiver participating in a randomized controlled trial of D-cycloserine or pill placebo augmented ERP. Participants completed validated assessments during treatment. Irritability was significantly and positively associated with depressive symptoms, defiance, functional impairment, and family accommodation, but was not associated with pretreatment OCD severity, symptom dimensions, obsessive beliefs. Irritability significantly declined following treatment, with over half of youth with any pretreatment irritability experiencing clinically significant change, though this change was not related to OCD improvement. Results suggest that irritability may be a marker of psychiatric comorbidity, parental accommodation, and impairment in youth with OCD. Implications for the exposure-based treatment of irritability are discussed.

Abstract
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.

Age moderated-anxiety mediation for multimodal treatment outcome among children with obsessive-compulsive disorder: An evaluation with correspondence analysis. J Affect Disord 2021; 282:766-775. [PMID: 33601717 PMCID: PMC9555304 DOI: 10.1016/j.jad.2020.12.198] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 11/02/2020] [Accepted: 12/28/2020] [Indexed: 01/04/2023]
Abstract
INTRODUCTION Anxiety expression varies by age in youth, and evaluation of putative mechanisms in treatment must consider both conjointly. Accordingly, age would moderate the mediation effect of anxiety in a youth obsessive-compulsive disorder (OCD) treatment trial. METHODS Fifty-six children ages 7 - 17 participated in an RCT comparing three treatments: CBT with standard dosing of sertraline, CBT with slow dosing of sertraline, and CBT with placebo. To examine the moderated-mediation effects for OCD symptom improvement, we discretized the continuous anxiety and OCD measures into three symptom outcome categories, "improved", "unchanged", and "deteriorated". To evaluate the moderating effect of age, we further examined the association of age and anxiety with the "improved" OCD category. For analysis, the age groups used as rows were cross tabulated with discretized anxiety and OCD measures. To estimate category associations with correlations, we adopted correspondence analysis. RESULTS The correlational results indicate that for all treatment conditions, age was a moderator of the mediation effect of physical anxiety symptoms for the improved OCD measures (outcomes). Specifically, age suppressed correlations with OCD outcomes, with Physical Symptoms as a mediator for the outcome measures. This moderated mediation effect was most evident for ages 8-10 in the CBT with placebo group. LIMITATIONS The moderated mediation effect manifest in this single RCT-based study should be validated in other studies. DISCUSSION Future research investigating a wider range of ages as a potential moderator of other symptom and emotion mediators of outcome is warranted, particularly in relation to individual symptom profiles of OCD.

Abstract
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.

Abstract
OBJECTIVES This study examined the phenomenology and predictors of early response and remission among youth with obsessive-compulsive disorder (OCD) receiving cognitive-behavioral therapy (CBT). METHODS One hundred and thirty-nine youth with a current primary diagnosis of OCD participated in this study. Participants received 10 sessions of CBT augmented by either placebo or d-cycloserine (DCS) as part of a randomized double-blind multi-site clinical trial. Early response and remission status were determined by clinician-rated global symptom improvement (CGI-I) and severity (CGI-S), respectively. RESULTS At the mid-treatment assessment, 45.3% of youth were early responders, and 28.1% were early remitters. At post-treatment assessment, 79.1% of youth were responders and 67.6% were remitters. Early response predicted a higher likelihood of post-treatment response and remission; early remission significantly predicted a higher likelihood of post-treatment remission. Bivariate logistic regressions showed that early response was predicted by lower baseline clinician-rated global severity (CGI-S) and lower depression severity; however, only depression severity remained a significant predictor in the multivariable logistic regression model. Furthermore, bivariate logistic regressions showed that early remission was predicted by lower baseline clinician-rated global severity (CGI-S), lower depression severity, and lower obsessive-compulsive symptom severity (CY-BOCS); however, only global severity remained a significant predictor in the multivariable logistic regression model. CONCLUSIONS Lower OCD and depression symptom severity predicted a greater likelihood of early treatment response and remission to CBT. Findings suggest that low OCD and depression symptom severity could serve as baseline characteristics to identify potential candidates for lower-intensity initial interventions in a stepped care approach. The modest predictive value of the variables examined suggests that additional factors could add to prediction of treatment response and remission.

Temporal precedence of the change in obsessive-compulsive symptoms and change in depressive symptoms during exposure and response prevention for pediatric obsessive-compulsive disorders. Behav Res Ther 2020; 133:103697.

Abstract
The current study examined the temporal precedence of change in obsessive-compulsive symptoms and change in depressive symptoms during the course of an Exposure and Response Prevention (ERP) for pediatric OCD. Participants included 142 children and adolescents (7-17 years; mean age = 12.39, SD = 2.92; 51.40% female; 60.40% Non-Hispanic White) with a primary or co-primary diagnosis of OCD who received ERP in a two-site randomized controlled trial on d-cycloserine augmentation of CBT for pediatric OCD. Participants completed clinician-administered assessments of OC symptoms (Children's Yale-Brown Obsessive Compulsive Scale) and depressive symptoms (Children's Depression Rating Scale-Revised) from baseline to post-treatment follow-up. Lagged mediational analyses did not yield evidence in support of a mediating role for the change in OC symptoms in the effect of ERP on the change in depressive symptoms. In contrast, change in depressive symptoms mediated the effect of ERP treatment on the subsequent change in OC symptoms (95% confidence interval for indirect effect = -0.04 to -0.001), though the effect size was small. Controlling for the prior levels of the depressive symptoms this indirect effect became non-significant. Theoretical and clinical implications of the findings for the youth with OCD and comorbid depression are discussed.

The Centrality of Doubting and Checking in the Network Structure of Obsessive-Compulsive Symptom Dimensions in Youth. J Am Acad Child Adolesc Psychiatry 2020; 59:880-889.

Abstract
OBJECTIVE Obsessive-compulsive disorder (OCD) is a heterogeneous condition with well-established symptom dimensions across the lifespan. The objective of the present study was to use network analysis to investigate the internal structure of these dimensions in unselected schoolchildren and in children with OCD. METHOD We estimated the network structure of OCD symptom dimensions in 6,991 schoolchildren and 704 children diagnosed with OCD from 18 sites across 6 countries. All participants completed the Obsessive-Compulsive Inventory-Child Version. RESULTS In both the school-based and clinic-based samples, the OCD dimensions formed an interconnected network with doubting/checking emerging as a highly central node, that is, having strong connections to other symptom dimensions in the network. The centrality of the doubting/checking dimension was consistent across countries, sexes, age groups, clinical status, and tic disorder comorbidity. Network differences were observed for age and sex in the school-based but not the clinic-based samples. CONCLUSION The centrality of doubting/checking in the network structure of childhood OCD adds to classic and recent conceptualizations of the disorder in which the important role of doubt in disorder severity and maintenance is highlighted. The present results suggest that doubting/checking is a potentially important target for further research into the etiology and treatment of childhood OCD.

Abstract
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.

Changes in Dosing and Dose Timing of D-Cycloserine Explain Its Apparent Declining Efficacy for Augmenting Exposure Therapy for Anxiety-related Disorders: An Individual Participant-data Meta-analysis.

Abstract
The apparent efficacy of d-cycloserine (DCS) for enhancing exposure treatment for anxiety disorders appears to have declined over the past 14 years. We examined whether variations in how DCS has been administered can account for this "declining effect". We also investigated the association between DCS administration characteristics and treatment outcome to find optimal dosing parameters. We conducted a secondary analysis of individual participant data obtained from 1047 participants in 21 studies testing the efficacy of DCS-augmented exposure treatments. Different outcome measures in different studies were harmonized to a 0-100 scale. Intent-to-treat analyses showed that, in participants randomized to DCS augmentation (n = 523), fewer DCS doses, later timing of DCS dose, and lower baseline severity appear to account for this decline effect. More DCS doses were related to better outcomes, but this advantage leveled-off at nine doses. Administering DCS more than 60 minutes before exposures was also related to better outcomes. These predictors were not significant in the placebo arm (n = 521). Results suggested that optimal DCS administration could increase pre-to-follow-up DCS effect size by 50%. In conclusion, the apparent declining effectiveness of DCS over time may be accounted for by how it has been administered. Optimal DCS administration may substantially improve outcomes.

Abstract
Family accommodation (FA) has been linked with myriad negative outcomes in pediatric obsessive-compulsive disorder (OCD), but extant literature has yielded differential relationships between FA and clinical variables of interest. Consequently, this study examined the phenomenology, clinical profile, and effects of comorbid psychopathology on FA to better understand these behaviors. A total of 150 youths and their caregivers completed clinician- and self-reported measures at a baseline visit for a larger randomized controlled trial. Sociodemographic variables were not associated with FA, but specific types of OCD symptom clusters were. Higher OC-symptom severity and functional impairment were associated with increased FA. Comorbid anxiety disorders moderated the relationship between OC-symptom severity and FA, but comorbid attention deficit hyperactivity, oppositional defiant, and mood disorders did not. Internalizing and externalizing problems both mediated the relationship between FA and functional impairment. These findings provide clinical implications for important treatment targets and factors that may impact FA.

Sudden gains in cognitive behavioral therapy among children and adolescents with obsessive compulsive disorder. J Behav Ther Exp Psychiatry 2019; 64:92-98.

Abstract
BACKGROUND AND OBJECTIVES This study examined the occurrence of sudden gains (or reversal of gains) among children with obsessive-compulsive disorder (OCD) during the course of cognitive-behavioral therapy (CBT), as well as the association of sudden gains with treatment response, treatment group, and pre-treatment clinical characteristics. METHODS The sample consisted of 136 youth (ages 7-17) with a primary diagnosis of OCD who were randomized in a double-blinded fashion to 10 sessions of CBT with augmentation of either d-cycloserine or placebo. Sudden gain status was determined based on clinician-rated obsessive-compulsive symptom severity, which was collected on 9 occasions across the study period. RESULTS 42.6% of youth experienced at least one sudden gain, which tended to occur either after starting exposure and response prevention or towards the end of treatment. After applying the Benjamini-Hochberg procedure for multiple comparisons, there were no significant pre-treatment predictors of sudden gains and only reduced insight predicted the reversal of gains. Individuals with at least one sudden gain had improved overall treatment outcomes, measured both by reduction in OCD symptom severity, and by global illness severity. LIMITATIONS Several clinical constructs were not examined. Symptomatology was not assessed at every treatment session. Differences in those who achieved sudden gains and those who did not may be obscured. There is the possibility that a sudden gain reflected a scoring error generated by an optimistic or inaccurate report. Finally, a relatively homogenous sample may limit the generalizability of results. CONCLUSIONS The course of CBT for pediatric OCD is variable with many children experiencing sudden gains, but a sizable percentage experience a reversal of gains which was related to reduced insight. Sudden gains tended to occur after starting exposure and response prevention and towards the end of treatment.

Abstract
Although obsessive-compulsive disorder (OCD) has often been characterized as an internalizing disorder, some children with OCD exhibit externalizing behaviors that are specific to their OCD. This study sought to demonstrate that parents perceive both internalizing and externalizing behaviors in childhood OCD by examining the factor structure of the Child Obsessive-Compulsive Externalizing/Internalizing Scale (COCEIS), a parent-report questionnaire intended to measure these constructs. This study also investigated clinical correlates of internalizing and externalizing factors in the COCEIS. A factor analysis of questionnaire responses from 122 parents of youth with OCD revealed both externalizing and internalizing factors in the COCEIS. Externalizing behaviors in childhood OCD were associated with other, co-occurring externalizing behavior problems, while both factors were positively correlated with OCD severity and co-occurring internalizing symptoms. They were positively associated with each other at a trend level, and neither showed a significant relationship with insight. Sixty-two percent of parents endorsed "often" or "always" to at least one externalizing item, though modal responses to items suggested that each individual feature captured by the COCEIS may be relatively uncommon. Mean responses were significantly greater for internalizing items. This study provides evidence for distinct but related externalizing and internalizing behaviors specific to childhood OCD. Treatment for children with OCD presenting with more externalizing behaviors may require a greater emphasis on behavioral parent training and motivational enhancement.

Fear extinction learning as a predictor of response to cognitive behavioral therapy for pediatric obsessive compulsive disorder. J Anxiety Disord 2019; 64:1-8. [PMID: 30852257 PMCID: PMC7422704 DOI: 10.1016/j.janxdis.2019.02.005] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Revised: 01/22/2019] [Accepted: 02/26/2019] [Indexed: 01/18/2023]
Abstract
BACKGROUND While cognitive behavior therapy (CBT) is an effective treatment for many children and adolescents with Obsessive Compulsive Disorder (OCD), therapeutic response is variable. Fear conditioning and extinction are central constructs underlying exposure-based CBT. Fear extinction learning assessed prior to CBT may be a useful predictor of CBT response for guiding treatment decisions. METHODS Sixty-four youth who participated in a randomized placebo-controlled trial of CBT with and without d-cycloserine (DCS) completed a fear conditioning task. Skin conductance response (SCR) scores were used to measure fear acquisition and extinction to determine whether extinction learning could predict CBT response. RESULTS CBT responders and non-responders appeared to acquire conditioned fear SCRs in a similar manner. However, differences between treatment responders and non-responders emerged during the extinction phase. A responder (responder, non-responder) by conditioned stimulus type (CS+, CS-) interaction showed that CBT responders differentiated the stimulus paired with (CS+) and without (CS-) the unconditioned stimulus correctly during early and late extinction, whereas the CBT non-responders did not (p = .004). CONCLUSIONS While the small sample size makes conclusions tentative, this study supports an emerging literature that differential fear extinction may be an important factor underlying clinical correlates of pediatric OCD, including CBT response.

Defining Treatment Outcomes in Pediatric Obsessive-Compulsive Disorder Using a Self-Report Scale. Behav Ther 2019; 50:314-324. [PMID: 30824248 PMCID: PMC6541025 DOI: 10.1016/j.beth.2018.06.003] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2018] [Revised: 06/08/2018] [Accepted: 06/18/2018] [Indexed: 01/05/2023]
Abstract
This study examined benchmarks of treatment response and clinical remission on the Obsessive Compulsive Inventory-Child Version (OCI-CV) for youth with obsessive-compulsive disorder (OCD). Participants were 91 youth who enrolled in a randomized controlled trial that examined the benefit of augmenting cognitive behavior therapy (CBT) with either d-cycloserine or placebo. Youth completed the OCI-CV at baseline, Week 4 (prior to initiating exposure therapy), and posttreatment. Receiver operator curve (ROC) analyses examined optimal benchmarks for treatment response and clinical remission as identified by independent evaluators at the posttreatment assessment using the Clinical Global Impression (CGI) scales of Improvement (CGI-Improvement), Severity (CGI-Severity), and Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Optimal benchmarks for treatment response were a 20%-25% reduction in the OCI-CV total score. Meanwhile, optimal benchmarks for remission were a 55%-65% reduction in the OCI-CV total score and a posttreatment total score ≤6-8. OCI-CV benchmarks exhibited moderate agreement with the CY-BOCS for treatment response and clinical remission. Meanwhile, fair agreement was observed for response and remission with CGI scales. A lower pretreatment OCI-CV total score was associated with less agreement between classification approaches. Findings provide benchmarks for classifying treatment response and clinical remission in an efficient manner. Given the moderate agreement between the CY-BOCS and OCI-CV benchmarks, the OCI-CV may serve as a useful alternative when clinician-rated scales cannot be administered due to limited resources (e.g., time, training). Thus, evidence-based measurement can be incorporated to monitor therapeutic response and remission in clinical practice.

Abstract
The purpose of this study was to examine differences in: (1) mental health emotional and behavioral problems between young children experiencing PTSD with and without MDD; (2) the incidence of caregiver PTSD and MDD between children with PTSD ± MDD; and (3) the number of traumatic events and interpersonal versus non-interpersonal nature of trauma events among children whose parents sought child trauma-focused treatment. Sixty-six caregivers of children aged 3-7 with PTSD completed semi-structured interviews regarding caregiver and child diagnoses, and caregivers completed self-report measures regarding child symptomatology. Results indicated that young children with PTSD + MDD had significantly higher internalizing symptoms, dissociative symptoms, and posttraumatic stress severity than those without comorbid MDD. There were no significant group differences in the incidence of caregiver PTSD or MDD, or the number or types of traumatic events. Future research to understand the unique contributors to the etiology of MDD in the context of PTSD among young children is needed.

A multicenter examination and strategic revisions of the Yale Global Tic Severity Scale. Neurology 2018; 90:e1711-e1719.

Abstract
OBJECTIVE To examine the internal consistency and distribution of the Yale Global Tic Severity Scale (YGTSS) scores to inform modification of the measure. METHODS This cross-sectional study included 617 participants with a tic disorder (516 children and 101 adults), who completed an age-appropriate diagnostic interview and the YGTSS to evaluate tic symptom severity. The distributions of scores on YGTSS dimensions were evaluated for normality and skewness. For dimensions that were skewed across motor and phonic tics, a modified Delphi consensus process was used to revise selected anchor points. RESULTS Children and adults had similar clinical characteristics, including tic symptom severity. All participants were examined together. Strong internal consistency was identified for the YGTSS Motor Tic score (α = 0.80), YGTSS Phonic Tic score (α = 0.87), and YGTSS Total Tic score (α = 0.82). The YGTSS Total Tic and Impairment scores exhibited relatively normal distributions. Several subscales and individual item scales departed from a normal distribution. Higher scores were more often used on the Motor Tic Number, Frequency, and Intensity dimensions and the Phonic Tic Frequency dimension. By contrast, lower scores were more often used on Motor Tic Complexity and Interference, and Phonic Tic Number, Intensity, Complexity, and Interference. CONCLUSIONS The YGTSS exhibits good internal consistency across children and adults. The parallel findings across Motor and Phonic Frequency, Complexity, and Interference dimensions prompted minor revisions to the anchor point description to promote use of the full range of scores in each dimension. Specific minor revisions to the YGTSS Phonic Tic Symptom Checklist were also proposed.

Abstract
OBJECTIVE The goal of this study was to investigate treatment histories and outcomes in a large community sample of youth with Pediatric Acute-onset Neuropsychiatric Syndrome (PANS), and, where appropriate, to examine the impact of immune deficiency on treatment outcomes. METHODS A comprehensive internet-based survey was completed by parents or guardians of youth who had received physician diagnoses of PANS, or by young adults (age 18+) who had themselves been diagnosed by a physician (N = 698). Data regarding the treatment histories of these patients, including the variety of medical and psychological treatments employed and the caregiver- or self-reported response to each, are presented. RESULTS The PANS patients in this study had commonly been treated with antibiotic (N = 675), anti-inflammatory (N = 437), and/or psychotropic therapy (N = 378). Response to antibiotic treatment was best when treatment was relatively aggressive, with broad-spectrum antibiotics and courses of >30 days generally producing the best results (i.e., up to 52% of patients achieving a "very effective" response). For immune-deficient patients (caregiver-reported laboratory studies below normal limits; N = 108), use of broad-spectrum antibiotics appeared to be particularly desirable. Anti-inflammatory therapies, including over-the-counter medications such as ibuprofen, were at least "somewhat effective" for most patients. Intravenous immunoglobulin (IVIG) had been used to treat PANS in 193 (28%) of the patients and was at least "somewhat effective" for 89%, although for 18% of these, the effect was not sustained. The highest rate of sustained response to IVIG treatment was seen in immune-deficient patients who received doses of at least 0.8 g/kg IVIG on a regular basis. Psychotropic medications, most commonly SSRIs (38% reported a trial), were commonly employed, but were often ineffective (e.g., 44% found SSRIs "somewhat" to "very effective"). Many patients (N = 473) had received some form of psychotherapy with some benefit, with cognitive behavioral therapy found to be at least somewhat effective in a majority of those treated with this modality. CONCLUSION Among the PANS patients represented in this study, relatively aggressive treatment courses targeted at eradicating infection and modulating the inflammatory response appeared to provide the best caregiver-reported therapeutic results, and to be generally well tolerated. Given its relative efficacy and tolerability, treatment targeting the inflammatory response may represent an underutilized approach in this population. The results of this study should be considered in light of the limitations inherent in a self-selected and administered online survey.

Abstract
OBJECTIVE The study examined clinical correlates of quality of life (QoL), impact of treatment on QoL, and predictors of QoL change among children with obsessive-compulsive disorder (OCD). METHODS One hundred forty-two children with primary OCD who were enrolled as part of a larger clinical trial participated. Children were administered a structured diagnostic interview, as well as clinician-administered measures of OCD and depression symptom severity. Children and parents completed reports of QoL, as well as measures of impairment and internalizing and externalizing symptoms. Youth received 10 sessions of family-based cognitive-behavioral therapy (CBT). RESULTS At baseline, QoL was inversely related to obsessive-compulsive symptom severity, impairment, externalizing and internalizing symptoms, and severity of depression symptoms according to children and parents. After CBT, QoL improved according to parent ratings, but not child ratings. None of the predictors examined were associated with changes in QoL scores over time. Impairment, and externalizing and internalizing symptoms predicted QoL after accounting for OCD symptom severity. After accounting for OCD symptoms, externalizing symptoms inversely predicted changes in QoL. CONCLUSION These data suggest that QoL is related to more severe clinical presentation and improves with evidence-based treatment, but QoL improvements may be inversely related to externalizing symptomology.

Abstract
OBJECTIVE To evaluate the tolerability, safety, and preliminary efficacy of extended-release guanfacine in children with chronic tic disorders, including Tourette's disorder (collectively referred to as CTD). METHODS This was a multisite, 8-week, randomized, double-blind, placebo-controlled trial. The primary outcome measure was the Yale Global Tic Severity Scale (YGTSS) total score. Key secondary outcomes included the Improvement item of Clinical Global Impressions-Improvement (CGI-I) scale and the Tic Symptom Self-report (TSSR). Adverse events were monitored at each visit. RESULTS Thirty-four subjects (23 boys and 11 girls) of ages 6 to 17 years (mean = 11.1 ± 3.1) with CTD were randomly assigned to extended-release guanfacine (n = 16) or placebo (n = 18). At baseline, the mean YGTSS total score was 26.3 ± 6.6 for the guanfacine group versus 27.7 ± 8.7 for the placebo group. Within the guanfacine group (mean final daily dose of 2.6 ± 1.1 mg, n = 14), the mean YGTSS total score declined to 23.6 ± 6.42 [t(15) = 1.84, p = 0.08; effect size = 0.35]. The results were similar in the placebo group with a score of 24.7 ± 10.54 at week 8 [t(17) = 1.83, p = 0.08; effect size = 0.38]. There was no significant difference in the rate of positive response on the CGI-I between the guanfacine group and placebo (19% [3/16] vs. 22% [4/18], p = 1.0). The most common adverse events were fatigue, drowsiness, dry mouth, headache, and irritability. Two subjects in the guanfacine group discontinued early-one because of an adverse event (depressed mood) and one because of lack of efficacy; two subjects in the placebo group discontinued because of lack of efficacy. CONCLUSIONS This pilot study did not confirm a clinically meaningful effect size within the guanfacine group. These results do not support the launch of a larger efficacy trial for tics in children and adolescents with CTD.

Abstract
OBJECTIVE To date, studies in the area of pediatric acute-onset neuropsychiatric syndrome (PANS; including pediatric autoimmune neuropsychiatric disorder associated with streptococcal infection [PANDAS] and pediatric infection-triggered neuropsychiatric disorder [PITAND]) have been relatively small and hence unable to comprehensively address questions of disease heterogeneity (e.g., by age, gender), comorbidities, and progression. In this study, we investigated an internet survey sample to more fully characterize the phenotypic traits; medical, family, and developmental history; functional challenges; and clinical course associated with PANS. METHODS Six hundred and ninety-eight patients with clinical diagnoses of PANS were included in this study. Participants, who included parents and legal guardians (for minors) or the PANS patients themselves (for those ages 18 and older), were asked to complete a 146-question survey designed to ascertain medical, developmental, and family history; PANS symptomatology; medical and nonmedical interventions for PANS; PANS course; PANS outcomes; and access to PANS care. RESULTS Our results agree with previous findings concerning the core symptoms of PANS as well as its male predominance (65% in this survey) and infection-triggered onset, thus validating the study population. Infection was implicated as the primary inciting factor in 65% of patients; 54% of patients reported an association with group A streptococcus specifically. The results of this survey also revealed new findings, including a surprisingly strong impact of gender and pubertal status on symptom course and chronicity, a high rate of medical comorbidity suggesting generalized immune dysfunction, a profound impact of PANS episodes on functional status, and a role for early resolution of infection through antibiotic treatment in disease course. CONCLUSIONS This study serves as the first survey of its size to provide insight into the global clinical picture and range of phenotypes of PANS patients. Significant results included the impact of gender and pubertal status on phenotype, affirmation of the role of the immune system in PANS pathology, and the role of timely resolution of infection in clinical outcomes. Understanding how PANS presents in a broad population-based sample, within the limitations of a self-selected and administered online survey, is an important step toward improving diagnosis, creating more targeted treatment options, educating the clinical and research community, and generating hypotheses for future prospective research.

Abstract
Objectives: Pediatric acute-onset neuropsychiatric syndrome (PANS) and its subset, pediatric autoimmune neuropsychiatric disorder associated with streptococcal infection (PANDAS), are emerging autoimmune encephalopathies of childhood. Management guidelines are needed. This article, from the PANS/PANDAS Consortium, presents a consensus management guideline for the infection components. Accompanying papers from the Consortium discuss psychiatric and immunomodulatory management. Methods: Literature was reviewed and integrated with the clinical experience of the authors to provide a set of practical guidelines. This article was submitted to all members of the PANS/PANDAS Consortium, and their additional comments were added. Results: The relationships between PANS and infections are reviewed. An approach to the retrospective diagnosis of group A streptococcal infection for an operational definition of PANDAS is proposed. An initial course of anti-streptococcal treatment is proposed for all newly diagnosed PANS cases. Chronic secondary antimicrobial prophylaxis is suggested for children with PANDAS who have severe neuropsychiatric symptoms or recurrent group A Streptococcus-associated exacerbations. Guidelines for children with non-streptococcal PANS include vigilance for streptococcal pharyngitis or dermatitis in the patient and close contacts. All patients with PANS or PANDAS should also be closely monitored for other intercurrent infections, including sinusitis and influenza. Intercurrent infections should be diagnosed and treated promptly according to current standard guidelines. A guideline for the assessment of infection at initial onset or during neuropsychiatric exacerbations is also presented. Standard immunizations and attention to vitamin D are encouraged. Data indicating limited utility of adenotonsillectomy and probiotics are presented. Conclusion: A working guideline for the management of infection issues in PANS and PANDAS, based on literature and expert opinion, is provided.

Abstract
OBJECTIVES Sudden and severe onset of obsessive-compulsive disorder (OCD) may present secondary to infectious and/or immune-mediated triggers. We assessed the preliminary efficacy, tolerability, and safety of azithromycin compared with placebo in the treatment of OCD and associated symptoms in children with pediatric acute-onset neuropsychiatric syndrome (PANS). METHODS Thirty-one youth aged 4-14 years (M = 8.26 ± 2.78 years, 62.5% male) were randomized to receive either placebo or azithromycin for 4 weeks (10 mg/kg up to 500 mg per day). Both groups were administered twice daily probiotics. The primary outcome, obsessive-compulsive symptom severity, was assessed using the OCD Clinical Global Impressions Severity (CGI-S OCD) and Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). RESULTS Participants in the azithromycin group (n = 17) showed significantly greater reductions in OCD severity on the CGI-S OCD than the placebo group (n = 14) posttreatment (p = 0.003), although there were no significant differences on the CY-BOCS. Significantly more participants in the azithromycin condition met treatment responder criteria on the CGI-I OCD at the end of week 4 (41.2%, n = 7) in comparison to the placebo group (7.1%, n = 1; p = 0.045). Tic severity moderated treatment response, with greater tic severity being associated with enhanced treatment response on the CGI-S OCD. Azithromycin was well tolerated with minimal adverse effects and no study dropouts due to side effects. However, the azithromycin group showed a trend toward significantly greater electrocardiography QTc (p = 0.060) at the end of week 4, and significantly more reports of loose or abnormal stools (p = 0.009). CONCLUSION This double blind pilot study suggests that azithromycin may be helpful in treating youth meeting the PANS diagnosis, especially those with elevated levels of both OCD and tic symptoms. Azithromycin was well tolerated, but the potential for cardiac risks suggests that additional monitoring may be needed to ensure safety.

Abstract
IMPORTANCE Whether and under which conditions D-cycloserine (DCS) augments the effects of exposure-based cognitive behavior therapy for anxiety, obsessive-compulsive, and posttraumatic stress disorders is unclear. OBJECTIVE To clarify whether DCS is superior to placebo in augmenting the effects of cognitive behavior therapy for anxiety, obsessive-compulsive, and posttraumatic stress disorders and to evaluate whether antidepressants interact with DCS and the effect of potential moderating variables. DATA SOURCES PubMed, EMBASE, and PsycINFO were searched from inception to February 10, 2016. Reference lists of previous reviews and meta-analyses and reports of randomized clinical trials were also checked. STUDY SELECTION Studies were eligible for inclusion if they were (1) double-blind randomized clinical trials of DCS as an augmentation strategy for exposure-based cognitive behavior therapy and (2) conducted in humans diagnosed as having specific phobia, social anxiety disorder, panic disorder with or without agoraphobia, obsessive-compulsive disorder, or posttraumatic stress disorder. DATA EXTRACTION AND SYNTHESIS Raw data were obtained from the authors and quality controlled. Data were ranked to ensure a consistent metric across studies (score range, 0-100). We used a 3-level multilevel model nesting repeated measures of outcomes within participants, who were nested within studies. RESULTS Individual participant data were obtained for 21 of 22 eligible trials, representing 1047 of 1073 eligible participants. When controlling for antidepressant use, participants receiving DCS showed greater improvement from pretreatment to posttreatment (mean difference, -3.62; 95% CI, -0.81 to -6.43; P = .01; d = -0.25) but not from pretreatment to midtreatment (mean difference, -1.66; 95% CI, -4.92 to 1.60; P = .32; d = -0.14) or from pretreatment to follow-up (mean difference, -2.98, 95% CI, -5.99 to 0.03; P = .05; d = -0.19). Additional analyses showed that participants assigned to DCS were associated with lower symptom severity than those assigned to placebo at posttreatment and at follow-up. Antidepressants did not moderate the effects of DCS. None of the prespecified patient-level or study-level moderators was associated with outcomes. CONCLUSIONS AND RELEVANCE D-cycloserine is associated with a small augmentation effect on exposure-based therapy. This effect is not moderated by the concurrent use of antidepressants. Further research is needed to identify patient and/or therapy characteristics associated with DCS response.

Abstract
Introduction Limited information is available regarding treatment practices in applied settings for children and adults with tic disorders (TDs). We describe, for the first time, the treatment of TDs in U.S. children and adults in the outpatient setting. Methods Data from the 2003-2010 National Ambulatory Medical Care Survey and the National Hospital Ambulatory Care Survey were used. Descriptive statistics for modality of treatment and class of pharmacological medications were reported by patient and visit characteristics. Separate multivariable logistic regression models were used to examine associations between patient and visit characteristics and classes of medications prescribed. Results One third (n = 99) of the sample did not receive any psychiatric or psychological treatment. Nearly two-thirds received a psychotropic medication. The most common class of medication was alpha-2 agonists (25%), followed by stimulants (23%), serotonin-reuptake inhibitors (SRIs) (19%), atypical antipsychotics (18%), anxiolytics (14%), anticonvulsants (11%), and typical antipsychotics (8%). Comorbid disorders and chronicity of problems were significantly associated with the receipt of certain classes of medications. Relatively few patients (18%) received psychotherapy. Conclusions If the decision is made to treat tic disorders, the choice of medication is dependent on the primary complaints, severity, chronicity, and the presence of comorbid psychiatric disorders. In general, comorbid externalizing, anxiety and mood disorders appear to influence treatment decisions in addition to TDs.

Structure and clinical correlates of obsessive-compulsive symptoms in a large sample of children and adolescents: a factor analytic study across five nations. Eur Child Adolesc Psychiatry 2017; 26:281-291.

Abstract
The underlying structure of obsessive-compulsive disorder (OCD) remains to be confirmed in child and adolescent populations. In this paper we report the first factor analytic study of individual OCD items from Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). OCD symptoms were assessed using the CY-BOCS symptom checklist in a sample of 854 patients with OCD (7-18 years of age) recruited from clinics in five countries. Pooled data were subjected to exploratory and confirmatory factor analysis (CFA) to identify the optimal factor structure. Various models were tested for age and gender subgroups. Also, the invariance of the solution across age and gender was tested and associations with demographic and clinical factors were explored. A three-factor model provided the best-fit solution. It consisted of the following factors: (1) harm/sexual, (2) symmetry/hoarding, (3) contamination/cleaning. The factor structure was invariant for age and gender across subgroups. Factor one was significantly correlated with anxiety, and factor two with depression and anxiety. Factor three was negatively correlated with tic disorder and attention-deficit/hyperactivity disorder (ADHD). Females had higher scores on factor two than males. The OCD symptom structure in children and adolescents is consistent across age and gender and similar to results from recent child and adolescents although hoarding may not be a separate factor. Our three-factor structure is almost identical to that seen in early studies on adults. Common mental disorders had specific patterns of associations with the different factors.

Abstract
BACKGROUND Tic disorders, including Tourette syndrome, are complex, multisymptom diseases, yet the impact of these disorders on affected children, families, and communities is not well understood. METHODS To improve the understanding of the impacts of Tourette syndrome, two research groups conducted independent cross-sectional studies using qualitative and quantitative measures. They focused on similar themes, but distinct scientific objectives, and the sites collaborated to align methods of independent research proposals with the aim of increasing the analyzable sample size. RESULTS Site 1 (University of Rochester) was a Pediatric Neurology referral center. Site 2 (University of South Florida) was a Child Psychiatry referral center. A total of 205 children with tic disorders were enrolled from both studies. The University of Rochester also enrolled 100 control children in order to clearly isolate impacts of Tourette syndrome distinct from those occurring in the general population. The majority of children with tic disorders (n = 191, 93.1%) had Tourette syndrome, the primary population targeted for these studies. Children with Tourette syndrome were similar across sites in terms of tic severity and the occurrence of comorbid conditions. The occurrence of psychiatric comorbidities in the control group was comparable with that in the general pediatric population of the United States, making this a well-justified comparison group. CONCLUSIONS Through collaboration, two sites conducting independent research developed convergent research methods to enable pooling of data, and by extension increased power, for future analyses. This method of collaboration is a novel model for future epidemiological research of tic disorders.

Abstract
BACKGROUND Fear acquisition and extinction are central constructs in the cognitive-behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive-behavioral therapy. Youths with OCD may have impairments in fear acquisition and extinction that carry treatment implications. METHODS Eighty youths (39 OCD, 41 healthy controls [HC]) completed clinical interviews, rating scales, and a differential conditioning task that included habituation, acquisition, and extinction phases. Skin conductance response (SCR) served as the primary dependent measure. RESULTS During habituation, participants with OCD exhibited a stronger orienting SCR to initial stimuli relative to HC participants. During acquisition, differential fear conditioning was observed for both groups as evidenced by larger SCRs to the visual conditioned stimulus paired with an aversive unconditioned stimulus (CS+) compared with a CS-; OCD participants exhibited a larger SCR to the CS+ relative to HC participants. The absolute magnitude of the unconditioned fear response was significantly larger in participants with OCD, compared with HC participants. During extinction, OCD participants continued to exhibit a differential SCR to the CS+ and CS-, whereas HC participants exhibited diminished SCR to both stimuli. CONCLUSIONS Participants with OCD exhibit a different pattern of fear extinction relative to HC participants, suggestive of greater fear acquisition and impaired inhibitory learning.

Abstract
OBJECTIVE The purpose of this article is to review the literature on hypothesized behavioral correlates of pharmacotherapy treatment response. A particular focus is placed on what have been referred to as "common factors" across mental health treatments, including medication adherence, therapeutic alliance, motivation for behavior change, and expectancies for positive treatment outcomes. These understudied factors may provide unique explanations for mechanisms of symptom change, patient risk as a result of protocol deviation, and attenuated treatment outcomes. METHOD A literature search was conducted to evaluate the relationship between treatment processes in pediatric psychiatry and medication adherence, therapeutic alliance, motivation for behavior change, and expectancies for positive treatment outcomes. RESULTS Substantial variability and room for improvement was identified for each common factor. Behavioral protocols have already been developed to address many aspects of common factors in pediatric psychiatric treatment, but are not yet a part of many practice parameters. CONCLUSION Interventions to improve common factors can be used immediately in tandem with psychopharmacological interventions to provide increased symptom relief and reduce patient risk. Furthermore, incorporating instruction in common factors interventions can positively affect training of future providers and enhance understanding of the mechanisms of effect of medications. An increased focus on common factors, with a particular emphasis on quantifying the magnitude and mechanisms of their effects on psychopharmacological interventions stand to benefit child patients, their families, treatment providers, training facilities, and pharmaceutical manufacturers.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) has been found to be highly comorbid in children and adolescents with obsessive-compulsive disorder (OCD). Some have proposed, however, that obsessive anxiety may cause inattention and executive dysfunction, leading to inappropriate ADHD diagnoses in those with OCD. If this were the case, these symptoms would be expected to decrease following successful OCD treatment. The present study tested this hypothesis and evaluated whether ADHD symptoms at baseline predicted OCD treatment response. Obsessive-compulsive and ADHD symptoms were assessed in 50 youth enrolled in a randomized controlled trial investigating selective serotonin reuptake inhibitor and cognitive behavioral treatment. Repeated-measures analysis of variance (RMANOVA) revealed that ADHD symptoms at baseline do not significantly predict treatment outcome. A multivariate RMANOVA found that OCD treatment response moderated change in inattention; participants who showed greater reduction in OCD severity experienced greater reduction in ADHD-inattentive symptoms, while those with less substantial reduction in obsessions and compulsions showed less change. These findings suggest that children and adolescents with OCD and inattention may experience meaningful improvements in attention problems following OCD treatment. Thus, in many youth with OCD, inattention may be inherently tied to obsessions and compulsions. Clinicians may consider addressing OCD in treatment before targeting inattentive-type ADHD.

An initial study of family accommodation in children and adolescents with chronic tic disorders. Eur Child Adolesc Psychiatry 2017; 26:99-109.

Abstract
This initial study examined the nature, incidence, and clinical correlates of family accommodation in youth with tic disorders, and validated a brief self-report measure of tic-related family accommodation, the Tic Family Accommodation Scale (TFAS). Seventy-five youth aged 6-18 who were diagnosed with a tic disorder and their parent completed a diagnostic clinical interview, and clinician and parent-report measures of tic severity, depressive symptoms, anxiety symptoms, behavioral problems, family accommodation and impairment. An exploratory factor analysis of the TFAS showed a two-factor structure, with good internal consistency for the Total score, Modification of Child Environment and Modification of Parent Environment subscales (α = 0.88, 0.86, and 0.81, respectively). Family accommodation was not associated with tic severity. Family accommodation was associated with increased anxiety and depressive symptoms, higher externalizing, rule breaking, aggressive behaviors and social problems, and with greater tic-related functional impairment. Anxiety and externalizing problems (but not depressive symptoms) predicted family accommodation when controlling for tic severity. Family accommodation predicted high levels of functional impairment over and above the effect of tic severity, anxiety, depression and externalizing problems. Family accommodation is a common phenomenon for youth with tic disorders, with modifications typically encompassing changes to the child and/or parent environments. Accommodation was not associated with tic severity, but was related to higher levels of anxiety, depressive symptoms, externalizing symptoms, aggression, and rule breaking behaviors. Results suggest that other emotional symptoms are more likely to drive accommodation practices than the tic symptoms per se.

The premonitory urge revisited: An individualized premonitory urge for tics scale. J Psychiatr Res 2016; 83:176-183. [PMID: 27643476 PMCID: PMC5107126 DOI: 10.1016/j.jpsychires.2016.09.007] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2016] [Revised: 07/27/2016] [Accepted: 09/08/2016] [Indexed: 11/19/2022]
Abstract
BACKGROUND Premonitory urge ratings have advanced our understanding of urge phenomenology among individuals with tic disorders (TD). However, these ratings have been limited by their reliance on a single global dimension of urge severity. This study examined the psychometric properties of a novel scale called the Individualized Premonitory Urge for Tics Scale (I-PUTS) that assesses urge severity across multiple dimensions (number, frequency, and intensity). METHOD Seventy-five youth with a TD and their parents participated. Clinicians assessed youth's tic severity, depression severity, rages, and premonitory urges. Parents completed ratings of youth's anxiety, affect lability, and general psychopathology. Youth completed self-report ratings of anxiety, urge severity, and distress tolerance. RESULTS The I-PUTS identified that youth experienced an average of three distinct urges, but had an average of seven tics over the past week. Urges were primarily localized in the head/face, neck/throat, and arm regions. All I-PUTS dimensions exhibited excellent inter-rater reliability. The I-PUTS dimensions exhibited good convergent validity with global urge ratings and tic severity, and appropriate divergent validity from other clinical constructs. Youth who exhibited discrepant reports between clinician-administered and self-report urge ratings had less anxiety and tic severity, and greater inattention and externalizing problems compared to youth who exhibited good agreement. CONCLUSIONS The I-PUTS is a reliable and valid assessment of urge phenomena, which provides additional and complementary information to existing urge scales. It highlights the existence of multiple dimensions of urge severity, and presents particular utility when assessing urges in youth with TD who have inattention and externalizing problems.

Abstract
IMPORTANCE Cognitive behavior therapy (CBT) among youth with obsessive-compulsive disorder (OCD) is effective, but many patients remain symptomatic after intervention. d-cycloserine, a partial agonist at the N-methyl-d-aspartate receptor in the amygdala, has been associated with enhanced CBT outcome for OCD among adults but requires evaluation among youth. OBJECTIVES To examine the relative efficacy of weight-adjusted d-cycloserine (25 or 50 mg) vs placebo augmentation of CBT for youth with OCD and to assess if concomitant antidepressant medication moderated effects. DESIGN, SETTING, AND PARTICIPANTS In a placebo-controlled randomized clinical trial, 142 youths (age range, 7-17 years) enrolled between June 1, 2011, and January 30, 2015, at 2 academic health science centers (University of South Florida and Massachusetts General Hospital) with a primary diagnosis of OCD were randomized in a double-blind fashion to d-cycloserine plus CBT or placebo plus CBT. Intent-to-treat analysis was performed. INTERVENTIONS Patients were randomly assigned in a 1:1 ratio to either 10 sessions of d-cycloserine plus CBT or placebo plus CBT. d-cycloserine (25 or 50 mg) or placebo was taken 1 hour before sessions 4 through 10. MAIN OUTCOMES AND MEASURES Children's Yale-Brown Obsessive Compulsive Scale at randomization, biweekly, midtreatment, and posttreatment. Secondary outcomes included the Clinical Global Impressions-Severity or Clinical Global Impressions-Improvement, remission status, Children's Depression Rating Scale, Multidimensional Anxiety Scale for Children, and Children's Obsessive-Compulsive Impact Scale-Parent Version. RESULTS The study cohort comprised 142 participants. Their mean (SD) age was 12.7 (2.9) years, and 53.5% (76 of 142) were female. A mixed-effects model using all available data indicated significant declines in the Children's Yale-Brown Obsessive Compulsive Scale total score and Clinical Global Impressions-Severity. No significant interaction between treatment group and changes in the Children's Yale-Brown Obsessive Compulsive Scale and Clinical Global Impressions-Severity indicated that the d-cycloserine plus CBT group and the placebo plus CBT group declined at similar rates per assessment point on the Children's Yale-Brown Obsessive Compulsive Scale total score (estimate, -2.31, 95% CI, -2.79 to -1.83 and estimate, -2.03, 95% CI, -2.47 to -1.58, respectively) and Clinical Global Impressions-Severity (estimate, -0.29, 95% CI, -0.35 to -0.22 and estimate, -0.23, 95% CI, -0.29 to -0.17, respectively). No group differences in secondary outcomes were present. Antidepressant medication use at baseline did not moderate changes for either group. CONCLUSIONS AND RELEVANCE d-cycloserine augmentation of CBT did not confer additional benefit relative to placebo among youth with OCD. Other augmentation approaches should be examined to enhance outcome. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00864123.

Abstract
BACKGROUND This study examined the incidence and clinical correlates of suicidal ideation (SI) in youth with tic disorders (TD). The independent contribution of tics, anxiety, depressive and externalizing symptoms on SI severity in youth with TD was assessed. METHOD Participants were 75 treatment-seeking youth with a TD (N=75) aged 6-18. Participants completed diagnostic assessments, clinician-ratings, self- and parent-report measures of emotional functioning and the presence and/or severity of suicidal ideation. RESULTS Based on youth-report, 61% of youth endorsed at least some symptoms of SI, and 8% endorsed symptoms that exceeded the clinically significant cut-off. Parents reported SI in 11% of cases, with generally poor agreement between parent- and youth-report. Suicidal ideation correlated with higher anxiety, depressive and externalizing symptoms, affective lability, and with poorer distress tolerance and overall functioning. Anxiety, depressive and externalizing symptoms showed an independent relationship with SI. Tic severity was not associated with SI. Rather, higher tic severity was associated with an increase in anxiety symptoms, which in turn, was associated with greater SI severity. LIMITATIONS Cross-sectional data limits causal conclusions. Diagnosis was based on unstructured assessments by expert clinicians, including consensus diagnosis, rather than structured clinical interviews. CONCLUSIONS Around 8-11% of youth with TD experienced SI. Tic severity did not have any direct influence on SI, however the presence of comorbid anxiety and depressive symptoms significantly increases this risk. Results suggest that it is psychiatric comorbidity, rather than tics themselves, that predispose youth with tic disorders to increased risk of suicidality.

Abstract
This case study describes the application of intensive cognitive-behavioral treatment (CBT), focusing on extinction and differential reinforcement of other behaviors (DRO), in an adolescent girl with primarily obsessional obsessive-compulsive disorder (OCD). “Abby,” a 13-year-old, Caucasian female, showed meaningful changes in OCD symptomatology during five consecutive sessions of intensive treatment. Abby’s mother also reported dramatic improvements in Abby’s functioning and in the mother-child relationship. Improvements continued to be reported by Abby and her mother and observed by therapists during follow-up sessions. The results of this case study provide preliminary support that intensive CBT incorporating extinction, cognitive restructuring skills, and DRO may be an effective treatment for pediatric OCD.

Abstract
OBJECTIVE Although evidence suggests that hoarding may be associated with symptoms of ADHD, no study has examined this relationship in children. METHOD Participants included 99 youth diagnosed with ADHD (and a parent) seen in a general outpatient psychiatry clinic. Children completed the Obsessive-Compulsive Inventory-Child Version, the Revised Child Anxiety and Depression Scale, and the Rosenberg Self-Esteem Scale. Parents completed the Children's Saving Inventory and Vanderbilt ADHD Diagnostic Rating Scale-Parent Version. RESULTS Inattentive and hyperactive/impulsive symptoms were the only indicator that differentiated those with and without clinically significant hoarding. Symptoms of ADHD, but not nonhoarding obsessive-compulsive symptoms, significantly predicted hoarding. Inattention and hyperactivity/impulsivity were uniquely associated with individual hoarding features. Hoarding symptoms mediated the relationship between ADHD and oppositionality. CONCLUSION These findings contribute to the growing literature about the association between hoarding and ADHD.

Abstract
BACKGROUND To compare the effectiveness and cost of stepped care trauma-focused cognitive behavioral therapy (SC-TF-CBT), a new service delivery method designed to address treatment barriers, to standard TF-CBT among young children who were experiencing posttraumatic stress symptoms (PTSS). METHODS A total of 53 children (ages 3-7 years) who were experiencing PTSS were randomly assigned (2:1) to receive SC-TF-CBT or TF-CBT. Assessments by a blinded evaluator occurred at screening/baseline, after Step One for SC-TF-CBT, posttreatment, and 3-month follow-up. TRIAL REGISTRATION ClinicalTrials.gov: https://www.clinicaltrials.gov/ct2/show/NCT01603563. RESULTS There were comparable improvements over time in PTSS and secondary outcomes in both conditions. Noninferiority of SC-TF-CBT compared to TF-CBT was supported for the primary outcome of PTSS, and the secondary outcomes of severity and internalizing symptoms, but not for externalizing symptoms. There were no statistical differences in comparisons of changes over time from pre- to posttreatment and pre- to 3-month follow-up for posttraumatic stress disorder diagnostic status, treatment response, or remission. Parent satisfaction was high for both conditions. Costs were 51.3% lower for children in SC-TF-CBT compared to TF-CBT. CONCLUSIONS Although future research is needed, preliminary evidence suggests that SC-TF-CBT is comparable to TF-CBT, and delivery costs are significantly less than standard care. SC-TF-CBT may be a viable service delivery system to address treatment barriers.

Abstract
BACKGROUND Fear acquisition and extinction are central constructs in the cognitive-behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive-behavioral therapy (CBT). Youth with OCD may have impairments in fear acquisition and extinction that carry treatment implications. We examined these processes using a differential conditioning procedure. METHODS Forty-one youth (19 OCD, 22 community comparisons) completed a battery of clinical interviews, rating scales, and a differential conditioning task that included habituation, acquisition, and extinction phases. Skin conductance response (SCR) served as the primary dependent measure. RESULTS During habituation, no difference between groups was observed. During acquisition, differential fear conditioning was observed across participants as evidenced by larger SCRs to the CS+ compared to CS-; there were no between-group differences. Across participants, the number and frequency of OCD symptoms and anxiety severity was associated with greater reactivity to stimuli during acquisition. During extinction, a three-way interaction and follow-up tests revealed that youth with OCD showed a different pattern of SCR extinction compared to the community comparison group. CONCLUSIONS Youth with OCD exhibit a different pattern of fear extinction relative to community comparisons. This may be attributed to impaired inhibitory learning and contingency awareness in extinction. Findings suggest the potential benefit of utilizing inhibitory-learning principles in CBT for youth with OCD, and/or augmentative retraining interventions prior to CBT to reduce threat bias and improve contingency detection.

Abstract
This study investigated the clinical correlates and mediators of self-concept in youth with Chronic Tic Disorders (CTD). Ninety-seven youth aged 6-17 (M = 11.1 ± 2.89; 79.4 % male) with CTD were administered the Yale Global Tic Severity Scale, the Piers-Harris Children's Self-Concept Scale-Second Edition, and self-report and clinician-administered measures assessing behavioral and psychological difficulties and comorbid conditions. Youth with CTD had a slightly below average level of self-concept, with 20 % (n = 19) exhibiting low self-concept. Youth with CTD-only had greater self-concept relative to youth with CTD and obsessive-compulsive disorder (OCD) (p = 0.04) or CTD, OCD, and attention deficit hyperactivity disorder (ADHD) combined (p = 0.009). Medium-to-large-sized associations were observed between youth's self-concept and clinical characteristics (e.g., severity of ADHD, OCD and depressive symptoms). Youth's self-concept partially mediated the relationship between tic severity and depressive symptom severity, and the interaction between tic impairment and youth's reliance on avoidant coping strategies moderated youth's self-concept. Implications, limitations, and recommendations for future interventions are discussed.

Abstract
Delivery systems other than in-office therapist-led treatments are needed to address treatment barriers such as accessibility, efficiency, costs, and parents wanting an active role in helping their child. To address these barriers, stepped care trauma focused-cognitive behavioral therapy (SC-TF-CBT) was developed as a parent-led, therapist-assisted therapy that occurs primarily at-home so that fewer in-office sessions are required. The current study examines caregivers' perceptions of parent-led (SC-TF-CBT) and therapist-led (TF-CBT) treatment. Participants consisted of 52 parents/care-givers (25-68 years) of young trauma-exposed children (3-7 years) who were randomly assigned to SC-TF-CBT (n = 34) or to TF-CBT (n = 18). Data were collected at mid-and post-treatment via interviews inquiring about what participants liked, disliked, found most helpful, and found least helpful about the treatment. Results indicated that parents/caregivers favored relaxation skills, affect modulation and expression skills, the trauma narrative, and parenting skills across both conditions. The majority of parents/caregivers in SC-TF-CBT favored the at-home parent-child meetings and the workbook that guides the parent-led treatment, and there were suggestions for improving the workbook. Reported disliked and least helpful aspects of treatments were minimal across conditions, but themes that emerged that will need further exploration included the content and structure, and implementation difficulties for both conditions. Collectively, these results highlight the positive impact that a parent-led, therapist-assisted treatment could have in terms of providing caregivers with more tools to help their child after trauma and reduce barriers to treatment.

Abstract
OBJECTIVE Activation Syndrome (AS) is a side-effect of antidepressants consisting of irritability, mania, self-harm, akathisia, and disinhibition. The current study was conducted to analyze how AS may hinder treatment outcome for multimodal treatment for children and adolescents with Obsessive-Compulsive Disorder. METHODS Fifty-six children or adolescents were recruited at two treatment sites in a double-blind randomized-controlled trial where participants received Cognitive-Behavioral Therapy and were randomized to slow titration of sertraline, regular titration of sertraline or placebo. RESULTS Using a recently developed measure of AS, results suggested that higher average levels of irritability, akathisia, and disinhibition significantly interfered with treatment response and explained 18% of the variance in obsessive-compulsive symptoms during treatment. Interestingly, only session-to-session increases in irritability resulted in a session-to-session increase in obsessive-compulsive symptoms. The observed results were unchanged with the addition of SSRI dosage as a covariate. CONCLUSIONS Results provide empirical support for the proposed hypothesis that AS may hinder multimodal treatment outcome for pediatric OCD. These findings suggest that dosage changes due to AS do not explain why those with higher AS had worse multimodal outcome. Other possible mechanisms explaining this observed disruption are proposed, including how AS may interfere with Cognitive-Behavioral Therapy.
