Abstract
A recent study identified three distinct treatment-response trajectories in pediatric OCD where higher levels of contamination symptoms predicted a limited response to cognitive-behavioral therapy (CBT). This study extends these findings by examining which specific symptoms characterize limited CBT response from baseline to 3-year follow-up, with an emphasis on contamination symptoms. The study sample comprised 269 pediatric patients with OCD, all receiving stepped-care treatment with manualized CBT. Differences in single item-reporting between the three trajectory groups were examined using linear mixed-effect modeling. Limited responders displayed a higher symptom load across all OCD symptom categories at 3-year follow-up, dominated by contamination symptoms. Five of these (obsessions about dirt and germs, about bodily fluids, about the feeling of contamination and compulsions regarding handwashing and showering) showed persistence from baseline to 3-year follow-up. The results indicate that presence of specific contamination symptoms may influence long-term symptom severity trajectories in young patients with OCD.

Behav Ther 2024; 55:306-319. [PMID: 38418042 DOI: 10.1016/j.beth.2023.07.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 06/27/2023] [Accepted: 07/03/2023] [Indexed: 03/01/2024]
Abstract
The current study investigates a novel digital tool designed to address barriers to out-of-session homework adherence in exposure with response prevention (ERP) for child obsessive-compulsive disorder (OCD). The OC-Go platform allows clinicians to create and push tailored interactive protocol- or symptom-specific assignments to patients on their mobile devices, providing in-the-moment step-by-step directions, encouragement, accountability, and a sense of therapeutic presence for patients during out-of-office exposures. The platform also facilitates objective measurement of homework and allows providers to support one another through a shared and searchable crowdsourced library with hundreds of assignable exposures and psychoeducation activities for specific OCD symptoms. The current study tested the usability and feasibility of the OC-Go platform with ERP stakeholders (OCD therapists, patients, and parents; N = 172) using the System Usability Scale (SUS). The study also tested the efficacy of OC-Go for augmenting homework adherence and clinical response using a randomized controlled, crossover design in a sample of 28 treatment-seeking youth with OCD. Participants randomized to standard ERP exhibited a homework adherence rate of 68.4% (95% CI [65.6, 71.0]), those randomized to ERP with OC-Go exhibited a greater adherence rate of 83.3% (95% CI [80.8, 85.6], p < .001). Both groups experienced large declines in Children's Yale-Brown Obsessive-Compulsive Scale-rated OCD (d = 1.31, p < .001), though participants randomized to begin ERP with OC-Go exhibited clinically significant greater improvement (p = .05), translating into an additional augmented treatment response at the Week 6 primary end point (d = 0.36) and the Week 12 treatment end point (d = 0.72). Stakeholders rated OC-Go in the 90th percentile for usability on the SUS, indicative of a highly usable and easy-to-learn technology. Initial evidence supports OC-Go as a feasible and effective adjunct to improve out-of-office exposure measurement, adherence, and treatment response in ERP for child OCD.

Abstract
Extant literature suggests a possible relationship between childhood trauma exposure and the development and trajectory of obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorder (OCD); however, this relationship is poorly understood. We conducted a systematic review that examined trauma exposure and OCS/OCD in youth. Primary inclusion criteria were English-language articles that addressed a sample with participants under 18 years of age. 46 articles met criteria for review, and were categorized into three groups of overlap: Post-traumatic Stress Disorder (PTSD) and OCS or OCD (n = 3), clearly defined Criterion A event trauma exposure and OCS or OCD (n = 30), and less well-defined potential trauma exposure and OCS or OCD (n = 13). There was mixed evidence linking trauma exposure and the development of OCS or OCD in youth. Major methodological limitations preclude formal conclusions. More research on co-occurring trauma exposure and OCD/OCS in youth is needed to advance research and improve treatment.

Abstract
Response Inhibition (RI) is the ability to suppress behaviors that are inappropriate for a given context. Obsessive-compulsive disorder (OCD) has been associated with impaired RI in adults as measured by the Stop Signal Task (SST). Conflicting results have been found in terms of the relationship between OCD severity and SST performance, and no studies to date have examined the relationship between SST and response to OCD treatment. Also relatively unknown is whether RI performance in OCD is associated with developmental or gender differences. This naturalistic study examined the relationship between SST performance, OCD severity, and OCD treatment response in a pediatric sample undergoing intensive treatment involving exposure and response prevention and medication management (n = 36). The SST and Children's Yale-Brown Obsessive Compulsive Scale (CYBOCS) were administered at admission and program discharge. OCD severity was not significantly related to stop signal reaction time (SSRT) in the whole sample and among subgroups divided by age and gender. Baseline SSRT and SSRT change did not predict CYBOCS change across treatment in the whole sample, but exploratory analyses indicated both were significant predictors among female adolescents. Results suggest there may be developmental gender differences in the relationship between RI and clinical improvement in pediatric OCD.

Extended treatment of multimodal cognitive behavioral therapy in children and adolescents with obsessive-compulsive disorder improves symptom reduction: a within-subject design. Child Adolesc Psychiatry Ment Health 2022; 16:99. [PMID: 36494821 PMCID: PMC9737735 DOI: 10.1186/s13034-022-00537-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 11/25/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Based on the current state of research regarding the treatment in pediatric obsessive-compulsive disorder (OCD), cognitive behavioral therapy (CBT) (in severe cases with additional pharmacotherapy) is considered as the first-line treatment according to internationally recognized guidelines. Research is mostly based on randomized controlled trials (RCTs; efficacy research). Thus, examined treatment conditions, especially the treatment duration, and patients' characteristics do not necessarily correspond to those found within routine care. Studies showed CBT packages as a whole to be efficacious, but less is known about the effects of individual CBT components. Furthermore, effects on comorbid symptoms or psychosocial impairment have been often neglected and different rater perspectives have been hardly considered in previous research. METHODS This effectiveness study aimed to examine the effects of multimodal CBT in children, adolescents, and young adults (age 6-20 years) with OCD (n = 38) within routine care. Effects on obsessive-compulsive and co-existing symptoms were evaluated in a within-subject design by comparing changes during the assessment phase with 12-week standard treatment and with individually tailored extended treatment. Additionally, within the standard treatment, non-exposure treatment was compared to exposure treatment. Multi-informant assessment was applied, and the analyses included multilevel modeling and t-tests for pre-post comparisons. RESULTS During the standard treatment and extended treatment, obsessive-compulsive symptoms, strain, and functional impairment significantly decreased. Moreover, a significant reduction of overall comorbid symptoms emerged, particularly regarding internalizing symptoms, including anxiety and depression. Comparisons of treatment components indicated that adding exposure with response prevention (ERP) has an additional positive effect. Clinical improvement and remission rates increased considerably when more treatment sessions were provided. CONCLUSIONS These results suggest that improvement after an initial 12-week course of treatment may not allow for the prediction of non-responders/non-remitters and for the termination of treatment. Overall, the findings show that results from randomized controlled trials are transferrable to routine care. Trial registration number This study was registered retrospectively at the German Clinical Trials Register ( https://drks.de/search/de/trial/DRKS00030050 ).

Abstract
The aim was to explore the potential clinical role of health anxiety (HA) symptoms in children and adolescents diagnosed with obsessive-compulsive disorder (OCD). The study investigated differences in demographic and various clinical variables between young people with OCD, with and without HA symptoms, and the effect of HA symptoms on overall OCD treatment outcome. The study sample comprised 269 children and adolescents with OCD (aged 7-17 years) from the large Nordic Long-term OCD Treatment Study. OCD symptoms and severity were assessed with The Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS), which includes one item regarding HA-like obsessions and one item regarding HA-like compulsions that were used to define the HA group. Several other instruments were used to assess comorbidity and other clinical aspects. All participants were treated with 14 weekly protocolled sessions of exposure-based cognitive behavioral therapy (CBT). HA symptoms were present in 31% of participants. Other anxiety symptoms and comorbid anxiety disorders were more prevalent among those with HA symptoms. These patients also presented with significantly more types of OCD symptoms. HA symptoms were reduced following OCD treatment with CBT and having HA symptoms did not affect CBT outcome. Results suggest that pediatric OCD with HA symptoms is characterized by more anxiety symptoms and a more heterogeneous OCD symptom profile. Standardized CBT seems equally effective in treating child and adolescent OCD with or without HA symptoms.Clinical trials registration: Nordic Long-term Obsessive-Compulsive Disorder Treatment Study: www.controlled-trials.com ; ISRCTN66385119.

Abstract
Abstract
Background
Obsessive-compulsive disorder (OCD) in children can lead to a huge burden on the concerned patients and their family members. While successful state-of-the art cognitive behavioral interventions exist, there is still a lack of available experts for treatment at home, where most symptoms manifest. Internet-based cognitive behavioral therapy (iCBT) could overcome these restrictions; however, studies about iCBT in children with OCD are rare and mostly target computerized self-help resources and only email contact with the therapist. Therefore, we intended to build up and to evaluate an iCBT approach for children with OCD, replacing successful elements of traditional in-office face-to-face CBT, with face-to-face teleconferences, online materials, and apps.
Methods
With the help of a pilot feasibility study, we developed the iCBT consisting of 14 teleconference sessions with the child and parents. The sessions are supported by an app assessing daily and weekly symptoms and treatment course completed by children and parents. Additionally, we obtain heart rate and activity scores from the child via wristbands during several days and exposure sessions. Using a waiting list randomized control trial design, we aim to treat and analyze 20 children with OCD immediately after a diagnostic session whereas the control group of another set of 20 OCD patients will be treated after waiting period of 16 weeks. We will recruit 30 patients in each group to take account for potential dropouts. Outcomes for the treatment group are evaluated before randomization (baseline, t0), 16 weeks (end of treatment, t1), 32 weeks (follow-up 1, t2), and 48 weeks after randomization (follow-up 2, t3). For the waiting list group, outcomes are measured before the first randomization (baseline), at 16 weeks (waiting list period), 32 weeks (end of treatment), 48 weeks after the first randomization (follow-up I), and 64 weeks after the first randomization (follow-up II).
Discussion
Based on our experience of feasibility during the pilot study, we were able to develop the iCBT approach and the current study will investigate treatment effectiveness. Building up an iCBT approach, resembling traditional in-office face-to-face therapy, may ensure the achievement of well-known therapy effect factors, the acceptance in both patients and clinicians, and the wide distribution within the health system.

Abstract
This study evaluated the psychometric properties of the Persian version of the Obsessive-Compulsive Inventory-Child Version (OCI-CV) in clinical and community samples. Factor structure (confirmatory factor analysis), validity (convergent/discriminant, and predictive), and reliability (internal consistency, and 4-week retest) of the Persian version of the OCI-CV were investigated in a sample of 391 children and adolescents 7-17 years comprised of two groups: a clinical sample of youth with OCD (n = 62), and a community sample (n = 329). Participants completed the OCI-CV, Multidimensional Anxiety Scale for Children (MASC), Children's Depression Inventory (CDI), and Child Behavior Checklist (CBCL). Similar to the English version of the OCI-CV, the Persian version of the scale demonstrated a stable six-factor structure, good convergent and discriminant validity through its correlations with other specific measures of pediatric psychopathology, acceptable sensitivity and specificity for the detection of OCD, and good reliability in terms of internal consistency and temporal stability. These findings suggest that the OCI-CV is a valid and reliable measure to assess obsessive-compulsive symptom dimensions in Iranian youth. Findings provide cross cultural support on the utility of OCI-CV as a self-report measure of obsessive-compulsive symptomology.

Abstract
Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder that is frequently diagnosed in children and adolescents. In pediatric OCD, family plays an important role in the development and maintenance of the disease. In this relationship, both genetic and behavioral factors, such as parental modeling and family accommodation, are significant. Parental modeling concerns the daily enactment of dysfunctional behavioral patterns by a parent with OCD, which may influence children. Family accommodation, in contrast, describes the direct participation of parents in their child's compulsive rituals, by modifying daily routines or by facilitating avoidance of OCD triggers, to decrease the child's distress and time spent executing compulsions. Approximately 80-90% of the relatives of OCD patients actively participate in patients' rituals. The literature demonstrates that a high level of family accommodation is associated with OCD symptom severity, reduced response to cognitive-behavioral treatment (CBT), and a higher risk of therapy dropout.Despite this, no studies have aimed at delineating practical guidance for psychotherapists to support parents in reducing family accommodation.The main aim of this paper is to propose a psychoeducation intervention focused on cognitive-behavioral strategies to help families to manage their child's OCD behaviors without enacting dysfunctional family accommodation behaviors in order to support their child's successful therapy.

Abstract
This study investigated whether an intensive group-based cognitive-behavioral therapy program with family involvement for children with anxiety disorders and obsessive-compulsive disorder could help reduce parental distress by addressing the larger family system. This study also examined associations between parental distress and parent-reported child outcomes of treatment. Two hundred ninety-nine children and adolescents, ages 6-19, who were patients in the intensive treatment program and their caregivers participated in this intervention-based study. Parents reported significant reductions in their own distress from admission to discharge, and greater reductions in parent-reported distress predicted greater reductions in parents' reports of their children's anxiety symptoms and the degree of child functional impairment. Higher levels of parent-reported parent mental health symptoms at children's admission and at discharge were associated with poorer levels of functioning in children at discharge. Parents' mental health symptoms may play a critical role in children and adolescents' treatment outcomes and therefore may need to be a separate treatment target.

Abstract
BACKGROUND AND OBJECTIVES Obsessive-compulsive disorder (OCD) is a disease that causes personal distress or social dysfunction, especially in childhood. The present study aimed to provide the prevalence, comorbidity, and predictors of OCD among children and adolescents. METHODS This was a cross-sectional national project conducted on 29,858 children and adolescents using the multi-stage cluster random sampling in Iran. There were both genders in each cluster and three age groups (6-9, 10-14, and 15-18 years) within each cluster. The tools used in this research included a demographic questionnaire and K-SADS-PL. To analyze the data, logistic regression and cross-tab tests were used. RESULTS According to the results, the prevalence of OCD in children and adolescents was 3.1 in boys and 3.8 in girls. Also, gender, age, place of residence, and history of psychiatric hospitalization of parents could predict OCD. OCD had comorbidity with behavioral disorders (OR = 0.60, 95%CI: 0.39-0.92), elimination disorders (OR = 0.50, 95%CI: 0.30-0.83), mood disorders (OR = 2.92, 95%CI: 1.43-5.94), and smoking and alcohol disorders (OR = 4.33, 95%CI: 1.28-14.63). CONCLUSION In the development of the obsessive-compulsive disorder, other disorders and symptoms also environmental factors can play a role and are important. Based on our findings, given the prevalence rate of OCD was higher in the age groups of 10-14 and 15-18 years, are one of the most important stages of development for the prevention and treatment of mental disorders, especially OCD, clinical specialists can design appropriate clinical trials or modify existing interventions based on the results of such research.

Abstract
Children who experience obsessive-compulsive symptoms (OCS) may be at risk for developing Obsessive-Compulsive Disorder (OCD). The current study aimed to investigate developmental trajectories of OCS, as well as possible predictors, within a community-based sample of children. Children (N = 1147) from the longitudinal NICHD Study of Early Child Care and Youth Development (SECCYD) were assessed for OCS, via the Child Behavioral Checklist - Obsessive-Compulsive Scale (OCS-8), eight times between Pre-Kindergarten (54 months; Pre-K) and High School (15 years of age; HS.) Participants were recruited within the United States and included only maternal caregivers. Preliminary analyses indicated that approximately 3% of the sample was above the diagnostic cutoff score on the OCS-8 at the High School time-point. Latent growth models tested symptom trajectories. Findings demonstrated three groups of OCS trajectories. Most children fell within a low symptomatology group (the No Peak group) with low OCS across all time points. Two additional OCS trajectories were also demonstrated: Pre-K Peak (high to low OCS across time) and HS Peak (low to high OCS across time). Both higher attention problems and greater depression/anxiety symptoms at the Pre-K time point predicted children's membership in the Pre-K Peak or HS Peak groups compared to the No Peak group. Membership within the HS Peak group predicted a high likelihood of children's OCS being above previously established cutoff scores for an OCD diagnosis at age 15 years. Membership within either the Pre-K Peak or No Peak groups predicted a low likelihood. This study provides new evidence for the existence of different developmental trajectories for youth with OCS. From a clinical perspective, these results may have important implications when considering the identification and early intervention of childhood OCS and OCD within the community.

Abstract
Although exposure-based cognitive behavior therapy (CBT) and pharmacotherapy have demonstrated efficacy for obsessive-compulsive disorder (OCD), the lack of clinicians effectively trained in these treatments significantly limit effective intervention options for affected youth. This is very unfortunate since child onset is reported by 50% of adults with OCD. To ameliorate this serious global issue the 14 nation International Obsessive-Compulsive Disorders Accreditation Task Force (ATF) of The Canadian Institute for Obsessive Compulsive Disorders (CIOCD) has developed knowledge and competency standards recommended for specialized treatments for OCD through the lifespan. Currently available guidelines are considered by experts to be essential but insufficient because there are not enough clinicians with requisite knowledge and competencies to effectively treat OCD. This manuscript presents knowledge and competency standards recommended for specialized cognitive behavior therapy (CBT) for pediatric OCD, derived from comprehensive literature review and expert synthesis. In addition to standards covering the elements of individual CBT-based assessment and treatment, family and school interventions are addressed given the critical role these domains play in the psychosocial development of youths. The ATF standards presented in these phase two papers will be foundational to the upcoming development of certification (individuals) and accreditation (sites) for specialized treatments in OCD through the lifespan.

Distinct trajectories of long-term symptom severity in pediatric obsessive-compulsive disorder during and after stepped-care treatment. J Child Psychol Psychiatry 2020; 61:969-978. [PMID: 31736082 DOI: 10.1111/jcpp.13155] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Revised: 09/02/2019] [Accepted: 10/09/2019] [Indexed: 01/25/2023]
Abstract
BACKGROUND First-line treatments for pediatric obsessive-compulsive disorder (OCD) include exposure-based cognitive-behavioral therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs). No studies have thus far identified distinct classes and associated predictors of long-term symptom severity during and after treatment. Yet, these could form the basis for more personalized treatment in pediatric OCD. METHOD The study included 269 OCD patients aged 7-17 years from the Nordic Long-term OCD Treatment Study (NordLOTS). All participants received stepped-care treatment starting with 14 weekly sessions of manualized CBT. Nonresponders were randomized to either prolonged CBT or SSRIs. Symptom severity was assessed using the Children's Yale-Brown Obsessive-Compulsive Scale at seven time points from pre- to post-treatment and over a three-year follow-up. Latent class growth analysis (LCGA) was performed to identify latent classes of symptom severity trajectories. Univariate and multivariate analyses were used to detect differences between classes and identify predictors of trajectory class membership including several clinical and demographic variables. TRIAL REGISTRY Nordic Long-term Obsessive-Compulsive Disorder (OCD) Treatment Study; www.controlled-trials.com; ISRCTN66385119. RESULTS Three LCGA classes were identified: (a) acute, sustained responders (54.6%); (b) slow, continued responders (23.4%); and (c) limited long-term responders (21.9%). Class membership was predicted by distinct baseline characteristics pertaining to age, symptom severity, contamination/cleaning and anxiety symptoms. CONCLUSIONS The LCGA suggests three distinct trajectory classes of long-term symptom severity during and after treatment in pediatric OCD with different clinical profiles at pretreatment. The results point to required clinical attention for adolescent patients with contamination/cleaning and anxiety symptoms who do not show convincing responses to first-line treatment even though they may have reached the established cutoff for treatment response.

Abstract
BACKGROUND AND PURPOSE Parents of children with obsessive-compulsive disorder (OCD) report significant emotional and socio-occupational impacts. There is, however, currently insufficient support for these parents. This study examined a mindfulness-based intervention for parents of OCD-affected children, investigating its feasibility and impact on parental ability to tolerate their child's OCD-related distress, in addition to exploring potential indirect effects. MATERIALS AND METHODS Parents of OCD-affected children (n = 39) completed an eight-week baseline observation period followed by eight, weekly manualized mindfulness-based intervention group sessions. Measures of parental tolerance of child distress, dispositional mindfulness, family accommodation, family functioning, and OCD symptom severity were collected. RESULTS In comparison to the baseline observation period, parental tolerance of child distress and dispositional mindfulness significantly improved following mindfulness training. No other temporal differences were observed. Parents reported high satisfaction. CONCLUSION Mindfulness-based skills training for parents of OCD-affected youth appears to be feasible and to significantly increase tolerance related to the child's distress.

Abstract
This study investigated whether intensive group-based cognitive-behavioral therapy (CBT) with family involvement for children with anxiety disorders and obsessive-compulsive disorder (OCD) would facilitate children's return to their daily routines. The focus shifted from the usual emphasis on remission to an improvement in functioning. The aim was to capture potentially missed gains when children pursue their fears and engage in more adaptive behaviors as these efforts may result in ongoing symptoms. Two hundred twelve children and adolescents aged 8-19 years old, who were patients in an intensive outpatient group-based treatment program at an academic hospital, participated in this study. Results indicated that both children and their parents endorsed significant improvement in children's functioning from admission to discharge. Symptom reduction was assessed for reference, and both children and parents reported significant decreases in child anxiety symptoms from admission to discharge, and children endorsed decreases in their comorbid depression symptoms. Short-term group-based intensive treatment in a clinical setting may help children return to their daily activities quickly.

Abstract
OBJECTIVE Identifying factors associated with early treatment response is important, because it can help allocate limited resources in psychiatric care more appropriately. This study examined baseline characteristics of participants with early response to exposure-based cognitive behavior therapy (CBT) for pediatric obsessive-compulsive disorder (OCD). METHOD 269 participants with OCD, aged 7-17 years, were enrolled in a 14-weeks CBT program. We identified participants with early response to treatment, (CY-BOCS total score of ≤15), by the seventh session. RESULTS At week 7, 248 (92.2%) participants were assessed, 38.3% (95% CI 32.4-44.5%, n = 95) were identified as treatment responders. Univariate analyses showed that six baseline characteristics were significantly associated with early treatment response: young age, lower levels of symptom severity, functional impairment, internalizing- and externalizing problems, depressive symptoms, and family accommodation. CONCLUSIONS These results suggested that treatment plans for younger children with moderate OCD symptoms and no major comorbid disorder should include briefer and less resource demanding treatment formats than the commonly recommended and applied standard doses of 15 CBT sessions.

Abstract
Little is known about the predictors of outcome from intensive residential treatment of OCD. This study aimed to examine age, gender, and baseline OCD severity, as well as measures of comorbid anxiety and depressive, internalizing/externalizing, and inattention symptoms, as predictors of treatment outcome in adolescents receiving intensive residential treatment for OCD. The sample comprised 314 adolescents aged 13-17 years with treatment-resistant OCD and a Children's Yale-Brown Obsessive-Compulsive Scale Self-Report (CY-BOCS-SR) total score ≥16. Bivariate and multiple regression models were used to evaluate the predictors of continuous OCD severity outcome and treatment response. Results of the bivariate regression analyses of predictors demonstrated that length of treatment, pre-treatment OCD severity, and symptoms of anxiety and depression significantly predicted post-treatment OCD severity, while only symptoms of depression and anxiety predicted treatment response. When including all predictors in the same model, only baseline OCD severity remained a significant predictor of post-treatment OCD severity, and none of the assessed variables significantly predicted treatment response. Results indicate that low pre-treatment OCD severity predicts lower OCD severity following treatment, although it did not predict treatment response.

Abstract
Pediatric obsessive-compulsive disorder (OCD) co-occurs frequently with other mental health conditions, adding to the burden of disease and complexity of treatment. Cognitive behavioral therapy (CBT) is efficacious for both OCD and two of its most common comorbid conditions, anxiety and depression. Therefore, treating OCD may yield secondary benefits for anxiety and depressive symptomatology. This study examined whether anxiety and/or depression symptoms declined over the course of OCD treatment and, if so, whether improvements were secondary to reductions in OCD severity, impairment, and/or global treatment response. The sample consisted of 137 youths who received 12 sessions of manualized CBT and were assessed by independent evaluators. Mixed models analysis indicated that youth-reported anxiety and depression symptoms decreased in a linear fashion over the course of CBT, however these changes were not linked to specific improvements in OCD severity or impairment but to global ratings of treatment response. Results indicate that for youth with OCD, CBT may offer benefit for secondary anxiety and depression symptoms distinct from changes in primary symptoms. Understanding the mechanisms underlying carryover in CBT techniques is important for furthering transdiagnostic and/or treatment-sequencing strategies to address co-occurring anxiety and depression symptoms in pediatric OCD.

Abstract
The current review provides an evidence base update of psychosocial treatments for self-injurious thoughts and behaviors (SITBs) in youth. A systematic search was conducted of 2 major scientific databases (PsycInfo and PubMed) and ClinicalTrials.gov for relevant randomized controlled trials (RCTs) published prior to June 2018. The search identified 26 RCTs examining interventions for SITBs in youth: 17 were included in the 2015 review and 9 trials were new to this update. The biggest change since the prior review was the evaluation of Dialectical Behavior Therapy for adolescents (DBT-A) as the first Level 1: Well-established intervention for reducing deliberate self-harm (composite of nonsuicidal and suicidal self-injury) and suicide ideation in youth and Level 2: Probably efficacious for reducing nonsuicidal self-injury and suicide attempts. Five other interventions were rated as Level 2: Probably efficacious for reducing SITBs in youth, with the new addition of Integrated Family Therapy. This evidence base update indicates that there are a few promising treatments for reducing SITBs in youth. Efficacious interventions typically include a significant family or parent training component as well as skills training (e.g., emotion regulation skills). Aside from DBT-A, few treatments have been examined in more than one RCT. Given that replication by independent research groups is needed to evaluate an intervention as Well-established, future research should focus on replicating the five promising interventions currently evaluated as Probably efficacious. In addition, an important future direction is to develop brief efficacious interventions that may be scalable to reach large numbers of youth.

Abstract
With the development of empirically supported treatments over the decades, have youth psychotherapies grown stronger? To investigate, we examined changes over time in treatment effects for four frequently treated youth mental-health problems: anxiety, depression, attention-deficit hyperactivity disorder (ADHD), and conduct disorders. We used PubMed and PsycINFO to search for randomized controlled trials (RCTs) that were published between January 1960 and May 2017 involving youths between the ages of 4 and 18 years. We also searched reviews and meta-analyses of youth psychotherapy research, followed reference trails in the reports we identified, and obtained additional studies identified by therapy researchers whom we contacted. We identified 453 RCTs (31,933 participants) spanning 53 years (1963-2016). Effect sizes for the problem-relevant outcome measures were synthesized via multilevel meta-analysis. We tracked temporal trends for each problem domain and then examined multiple study characteristics that might moderate those trends. Mean effect size increased nonsignificantly for anxiety, decreased nonsignificantly for ADHD, and decreased significantly for depression and conduct problems. Moderator analyses involving multiple study subgroups showed only a few exceptions to these surprising patterns. The findings suggest that new approaches to treatment design and intervention science may be needed, especially for depression and conduct problems. We suggest intensifying the search for mechanisms of change, making treatments more transdiagnostic and personalizable, embedding treatments within youth ecosystems, adapting treatments to the social and technological changes that alter youth dysfunction and treatment needs, and resisting old habits that can make treatments unduly skeuomorphic.

Abstract
Efficacious psychological treatments exist for a variety of mental health conditions, but many who could benefit from these treatments do not receive them. Increasing efforts have been made to disseminate effective protocols, and several approaches for implementing such treatments have been proposed, including the use of protocols, principles, practices, and policies. We discuss the relative merits of disseminating protocols, and highlight the importance of employing flexibility within fidelity. We describe the benefits of using protocols, including their empirical support, guidance for decision making, and structure to facilitate training and enhance treatment integrity. We also address several criticisms that have been offered against protocols, citing data that indicates that many of the criticisms are not warranted.

Abstract
Evidence for using cognitive-behavioral therapy (CBT) for the treatment of obsessive-compulsive disorder (OCD) in young people emphasizes the use of exposure with response prevention (ERP) as the key ingredient. CBT with a cognitive focus is used more often in adults, and comparatively there is less evidence for its use with young people. Although a significant proportion of young people with OCD respond well to CBT using ERP, a subset does not. Therefore, there is a need to consider alternative approaches. This case study describes the treatment of a 15-year-old girl with severe OCD using a cognitive approach. This case identifies the criteria used to make the decision to use a cognitive over an ERP approach and highlights the differences between the treatments. This case study demonstrates the merit of considering the cognitive approach to treatment of OCD for some young people.

Abstract
BACKGROUND Over half of children receiving cognitive behavioral therapy (CBT) for obsessive compulsive disorder (OCD) do not fully remit. To improve response rates and enhance extinction learning, d-cycloserine (DCS) has been examined as an augmenting agent of CBT. To direct children with OCD towards treatments with the highest likelihood of success, the current study evaluated the conditions under which DCS augmentation works best (i.e., moderators) and the baseline characteristics associated with outcome, irrespective of treatment type (i.e., predictors). METHODS Data came from a two-site randomized controlled trial (N = 142) in which children received either DCS + CBT (n = 70) or placebo + CBT. RESULTS No baseline variables moderated the effects of DCS augmentation on CBT outcome. However, several predictor variables were associated with a decreased likelihood of achieving remission status, including higher family accommodation scores, higher impairment scores, higher depression scores, and higher externalizing scores. Furthermore, better insight at pre-treatment was associated with more improvement longitudinally on a clinician-rated summary measure of illness severity. LIMITATIONS The current study did not examine all variables that had previously been shown to moderate or predict treatment outcome (e.g., family history of OCD or cognitive profile). CONCLUSIONS The absence of significant moderators suggests that baseline factors cannot yet be used to determine who benefits most from DCS. To maximize treatment benefits for children presenting with identified predictors of worse treatment outcome, clinicians might need to adapt existing CBT protocols and administer additional interventions that address patients' specific problem areas.

Coercive and disruptive behaviors mediate group cognitive-behavioral therapy response in pediatric obsessive-compulsive disorder. Compr Psychiatry 2018; 86:74-81. [PMID: 30081210 DOI: 10.1016/j.comppsych.2018.07.012] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2018] [Revised: 06/12/2018] [Accepted: 07/13/2018] [Indexed: 01/01/2023] Open
Abstract
PURPOSE Coercive and disruptive behaviors (CDBs) are commonplace in pediatric obsessive-compulsive disorder (OCD) and are associated with increased disorder impact and reduced treatment response. Prior research suggests that CDBs mediate the cross-sectional relationship between family accommodation and OCD symptom severity; however, the impact of reducing CDBs on other treatment outcomes has yet to be studied. METHODS Participants comprised 49 OCD-affected youth (42.9% male, Mage at baseline = 13.7) and their parent(s) who completed a 12-week, group family-based cognitive-behavioral treatment at an OCD specialty clinic. Outcomes included parent-report measures of CDBs, family accommodation, symptom severity, and both child- and family-level impairment. Descriptive, correlation, and regression analyses were followed by tests of indirect effects (mediation). RESULTS Changes in all outcome variables had moderate to strong correlations with each other. As hypothesized, CDB decreases predicted positive changes in OCD severity as well as in child and family impairment. Further, whereas improvement in OCD severity predicted changes in child and family impairment, improvements in family accommodation were not directly predictive of any outcomes. Consistent with hypotheses, changes in CDBs mediated relationships between changes in accommodation and child- and family-level impairment, as well as relationships between changes in OCD severity and both levels of impairment. Additional exploratory analyses found that changes in symptom severity significantly mediated relationships between changes in CDBs and both levels of impairments. CONCLUSIONS Findings suggest that attention to reducing CDBs is warranted in the treatment of pediatric OCD, and that accommodation reductions lead to meaningful improvements in child and family functioning only when CDBs and/or symptoms are also reduced. Future family-based treatments may benefit from inclusion of components specifically targeting CDBs that occur within the context of accommodating OCD symptoms.

Abstract
This study reports follow-up 2 and 3 years after the initial assessment of a sample of youth with a primary diagnosis of OCD. Participants were 109 children and adolescents, aged 5-17 years, recruited from a specialized, outpatient OCD clinic in Sweden. Patients were treated with cognitive behavioral therapy (CBT), augmented when indicated by selective serotonin reuptake inhibitor (SSRI). In cases where SSRIs were insufficient, augmentation with a second-generation antipsychotic (SGA) was applied. Participants were assessed with the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS), Children's OCD Impact Scale (COIS), and Children's Depressive Inventory (CDI) at follow-ups 2 and 3 years after baseline assessment. Treatment response was defined as CY-BOCS total score ≤ 15, and remission was defined as CY-BOCS total score ≤ 10. Analyzing the outcomes with linear mixed-effects models (LME) showed a decrease in OCD symptom load from 23 to 6.9 at the 3-year follow-up. Moreover, two of three (66.1%) participants were in remission, and another 19.2% had responded to treatment at the 3-year follow-up. Thus, 85.3% of participants responded to treatment. Moreover, during the follow-up period, participants' psychosocial functioning had significantly improved, and depressive symptoms had significantly decreased. The results suggest that evidence-based treatment for pediatric OCD, following expert consensus guidelines, has long-term positive effects for most children and adolescents diagnosed with OCD. The results also indicate that improvements are maintained over a 3-year period, at least, and that improvement is also found with regard to psychosocial functioning and depressive symptoms.

Exposure therapy for youth with anxiety: Utilization rates and predictors of implementation in a sample of practicing clinicians from across the United States. J Anxiety Disord 2018; 58:8-17.

Abstract
Exposure therapy is a highly effective, evidence-based treatment technique for children and adolescents with anxiety disorders. Regardless, therapists in the community are reported to use exposure relatively rarely compared with other approaches. The goal of the present study was to identify how practicing clinicians treat youth with anxiety disorders across the United States and what factors contribute to their use of exposure therapy. Recruited from public directories, 257 private practice therapists who treat anxious youth were surveyed. Non-exposure cognitive-behavioral techniques like cognitive restructuring and relaxation techniques were used significantly more frequently than exposure. Providers with more training in exposure therapy and fewer negative beliefs about this approach reported using exposure significantly more in the treatment of youth with social anxiety, obsessive-compulsive, and panic disorders. Self-identification as an anxiety disorder specialist significantly predicted exposure use for youth with posttraumatic stress disorder. Most therapists in private practice have minimal training in exposure therapy, perceive a lack of training options, and believe there would be a benefit to acquiring more training. The implications of these findings are discussed, including how to optimally design training opportunities in exposure therapy.

Abstract
Neurofeedback - learning to modulate brain function through real-time monitoring of current brain state - is both a powerful method to perturb and probe brain function and an exciting potential clinical tool. For neurofeedback effects to be useful clinically, they must persist. Here we examine the time course of symptom change following neurofeedback in two clinical populations, combining data from two ongoing neurofeedback studies. This analysis reveals a shared pattern of symptom change, in which symptoms continue to improve for weeks after neurofeedback. This time course has several implications for future neurofeedback studies. Most neurofeedback studies are not designed to test an intervention with this temporal pattern of response. We recommend that new studies incorporate regular follow-up of subjects for weeks or months after the intervention to ensure that the time point of greatest effect is sampled. Furthermore, this time course of continuing clinical change has implications for crossover designs, which may attribute long-term, ongoing effects of real neurofeedback to the control intervention that follows. Finally, interleaving neurofeedback sessions with assessments and examining when clinical improvement peaks may not be an appropriate approach to determine the optimal number of sessions for an application.

Abstract
The present study explored the concept of tolerance for child distress in 46 children (ages 5-8), along with their mothers and fathers, who received family-based CBT for OCD. The study sought to describe baseline tolerance, changes in tolerance with treatment, and the predictive impact of tolerance on symptom improvement. Tolerance was rated by clinicians on a single item and the CY-BOCS was used to measure OCD severity. Descriptive results suggested that all participants had some difficulty tolerating the child's distress at baseline while paired t tests indicated large improvements were made over treatment (d = 1.2-2.0). Fathers' initial tolerance was significantly related to symptom improvement in a multivariate regression as were fathers' and children's changes in distress tolerance over the course of treatment. Overall, results provide support for examining tolerance of child distress including its predictive impact and potential as a supplemental intervention target.

Abstract
This open, uncontrolled study examined the efficacy of a group family-based cognitive behavioral therapy (GF-CBT) protocol in treating pediatric obsessive-compulsive disorder (OCD) and explored predictors of symptom improvement. Eighty-five OCD-affected youth aged 8-18 years (M = 13.9 years, SD = 2.49; 46% male) and their parent(s) participated in a weekly, 12-session GF-CBT program. Data from multiple perspectives were gathered at the beginning and end of treatment, as well as at one-month follow-up. A broad range of assessment measures were utilized to capture clinically-relevant domains and a number of potential predictor variables were explored. Paired t-tests indicated that treatment was associated with significant reductions in clinician- and parent-rated OCD severity (d = 1.47, 1.32), youth and parent-rated functional impairment (d = 0.87, 0.67), coercive/disruptive behaviors (d = 0.75), and family accommodation (d = 1.02), as well as improvements in youth-, mother-, and father-rated family functioning (d = 1.05, 0.50, 0.88). Paired t-tests also indicated that youth remained improved at one-month follow-up. Step-wise regression identified greater homework success as a significant predictor of symptom improvement. This study provides evidence that GF-CBT significantly improves a wide range of domains for youth/families that extends beyond OCD symptom severity and supports homework as a core treatment component.

One-Year Outcome for Responders of Cognitive-Behavioral Therapy for Pediatric Obsessive-Compulsive Disorder. J Am Acad Child Adolesc Psychiatry 2017; 56:940-947.e1.

Abstract
OBJECTIVE This study describes 1-year treatment outcomes from a large sample of cognitive-behavioral therapy (CBT) responders, investigates age as a possible moderator of these treatment outcomes, and evaluates clinical relapse at the 1-year follow-up. METHOD This study is the planned follow-up to the Nordic Long-term OCD [obsessive-compulsive disorder] Treatment Study (NordLOTS), which included 177 children and adolescents who were rated as treatment responders following CBT for OCD. Participants were assessed with the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) at 6- and 12-month follow-up. Treatment response and remission were defined as CY-BOCS total scores ≤15 and ≤10, respectively. Linear mixed-effects models were used to analyze all outcomes. RESULTS At 1 year, a total of 155 children and adolescents (87.6%) were available for follow-up assessment, with 142 of these (91.6%) rated below a total score of ≤15 on the CY-BOCS. At 1-year follow-up, 121 (78.1%) were in remission. On average, CY-BOCS total scores dropped by 1.72 points during the first year after terminating treatment (p = .001). A total of 28 participants (15.8%) relapsed (CY-BOCS ≥ 16) at either the 6- or 12-month assessment; only 2 patients required additional CBT. CONCLUSION Results suggest that manualized CBT in a community setting for pediatric OCD has durable effects for those who respond to an initial course of treatment; children and adolescents who respond to such treatment can be expected to maintain their treatment gains for at least 1 year following acute care.

Abstract
UNLABELLED The Pediatric Obsessive-Compulsive Disorder Treatment Study II (POTS II) investigated the benefit of serotonin reuptake inhibitor (SRI) augmentation with cognitive behavioral therapy (CBT). Primary outcomes focused on OCD symptom change and indicated benefit associated with a full course of CBT. Given that the majority of youth with OCD suffer from significant comorbid symptoms and impaired quality of life, the current study examined POTS II data for effects on secondary outcomes. Participants were 124 youth ages 7-17 years with a primary diagnosis of OCD who were partial responders to an adequate SRI trial. Participants were randomized to medication management, medication management plus instructions in cognitive behavioral therapy (CBT), or medication management plus full CBT. Acute effects on non-OCD anxiety, depression, inattention, hyperactivity, and quality of life were examined across treatment conditions. Improvement across treatment was observed for non-OCD anxiety, inattention, hyperactivity, and quality of life. Changes were generally significantly greater in the group receiving full CBT. Child-rated depression was not found to change. OCD-focused treatment lead to improvement in other areas of psychopathology and functioning. For youth who are partial responders to SRI monotherapy, augmentation with full CBT may yield the greatest benefit on these secondary outcomes.

The Treatment Worries Questionnaire: Conjoined measures for evaluating worries about psychosocial treatment in youth and their parents. Psychiatry Res 2017; 250:159-168.

Abstract
Treatment worries, which surround requirements and results of obtaining treatment, may represent an important construct; however, previous measures were limited by their specificity, format, and lack of parent report. Therefore the present study examined the initial outcomes and psychometrics of corresponding measures of treatment worries in youth (Treatment Worries Questionnaire - Child; TWQ-C) and their parents (Treatment Worries Questionnaire - Parent; TWQ-P). Participants were 94 youth (7-17-years old) and parent dyads presenting for treatment of an anxiety disorder. Dyads completed the TWQ-C and TWQ-P along with additional measures prior to initiating treatment. Treatment worries were endorsed in the mild-moderate range by youth and the TWQ-C demonstrated good-excellent internal consistency, a three-factor structure, and consistent convergent and divergent relationships. Treatment worries were endorsed in the low-mild range by parents and the TWQ-P demonstrated fair-good internal consistency, a four-factor structure, and consistent divergent relationships, but variable (by factor) convergent relationships. The results provide information on treatment worries and support the use of the TWQ-C and TWQ-P as broad assessments of the concept. Low endorsement of worries among parents likely relates to the treatment-seeking nature of the sample. Future investigations using the TWQ-C and TWQ-P in a variety of samples is warranted.

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
Prior research has identified OCD subtypes or "clusters" of symptoms that differentially relate to clinical features of the disorder. Given the high comorbidity between OCD and anxiety, OCD symptom clusters may more broadly associate with fear and/or distress internalizing constructs. This study examines fear and distress dimensions, including physical concerns (fear), separation anxiety (fear), perfectionism (distress), and anxious coping (distress), as predictors of previously empirically-derived OCD symptom clusters in a sample of 215 youth diagnosed with primary OCD (ages 7-17, mean age = 12.25). Self-reported separation fears predicted membership in Cluster 1 (aggressive, sexual, religious, somatic obsessions, and checking compulsions) while somatic/autonomic fears predicted membership in Cluster 2 (symmetry obsessions and ordering, counting, repeating compulsions). Results highlight the diversity of pediatric OCD symptoms and their differential association with fear, suggesting the need to carefully assess both OCD and global fear constructs that might be directly targeted in treatment.

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.

Abstract
Cognitive-behavioral therapy (CBT) using exposure with response prevention (ERP) is the treatment of choice for obsessive-compulsive disorder (OCD); however, developmental modifications should be considered when treating young children. This article presents a case study illustrating family-based CBT using ERP with a 7-year-old boy. The delivery of ERP for this case was guided by 3 main principles: (a) family involvement with a focus on reducing family accommodation, (b) understanding the functional relation between the client's obsessions and compulsions, and (c) creating conditions to facilitate habituation during exposure. Outcomes for this case indicate significant improvement in functioning and OCD symptoms. Results highlight the importance of family involvement and the applicability of using a function-based habituation framework when delivering ERP to this unique population.

Abstract
Compulsivity is the defining feature of various psychiatric disorders including Obsessive Compulsive Related Disorders (OCRDs), and other compulsive, impulsive, and addictive disorders. These disorders are disabling, chronic conditions with an early onset and high rates of comorbidity, misdiagnoses, and delay in treatment onset. Disorders of compulsivity are responsible for considerable socioeconomic burden to society. We review the costs and impacts of compulsivity. In order to facilitate earlier diagnosis and targeted treatments, we examine the overlapping mechanisms that underlie compulsivity. We reconceptualize psychiatric disorders based on core features of compulsivity, highlight challenges in harmonizing research in children and adults, describe newer research methodologies, and point to future directions that can impact the costs and impact of disorders of compulsivity.

Abstract
Recent research on the treatment of adults with anxiety disorders suggests that aspects of the in-session exposure therapy process are relevant to clinical outcomes. However, few comprehensive studies have been conducted with children and adolescents. In the present study, 35 youth diagnosed with primary obsessive-compulsive disorder (OCD; M age = 12.9 years, 49% male, 63% Caucasian) completed 12 sessions of exposure and response prevention (ERP) in one of two treatment conditions as part of a pilot randomized controlled testing of a family focused intervention for OCD. Key exposure process variables, including youth self-reported distress during ERP and the quantity and quality of ERP completed, were computed. These variables were examined as predictors of treatment outcomes assessed at mid-treatment, post-treatment, and three-month follow-up, partialing treatment condition. In general, greater variability of distress during ERP and completing a greater proportion of combined exposures (i.e., exposures targeting more than one OC symptom at once) were predictive of better outcomes. Conversely, greater distress at the end of treatment was generally predictive of poorer outcomes. Finally, several variables, including within- and between-session decreases in distress during ERP, were not consistently predictive of outcomes. Findings signal potentially important facets of exposure for youth with OCD and have implications for treatment. A number of results also parallel recent findings in the adult literature, suggesting that there may be some continuity in exposure processes from child to adult development. Future work should examine additional measures of exposure process, such as psychophysiological arousal during exposure, in youth.

Abstract
Levels of parental expressed emotion (EE) are prospectively associated with the symptomatic course of a range of childhood psychiatric disorders. This article reviews the literature linking parental EE to youth psychopathology and proposes a novel framework for understanding its mechanisms of action. We find that, despite noteworthy methodological limitations, parental EE is linked consistently to a more deleterious course of mood, anxiety, and psychotic disorders in youth. Its mechanism of action is unknown. Models of "toxic family stress" (referring to frequent, sustained, and uncontrollable stress without protective influences) provide one framework for understanding how high EE environments interact with individual biological vulnerabilities to promote illness onset and recurrence. Research aimed at understanding biological responses (e.g., stress reactivity, arousal) to familial EE is needed. Such work may inform efforts to understand how EE affects the course of psychiatric disorders and may guide the development of novel interventions emphasizing emotion regulation strategies.

A META-ANALYSIS OF COGNITIVE BEHAVIOR THERAPY AND MEDICATION FOR CHILD OBSESSIVE-COMPULSIVE DISORDER: MODERATORS OF TREATMENT EFFICACY, RESPONSE, AND REMISSION. Depress Anxiety 2015; 32:580-93. [PMID: 26130211 PMCID: PMC4515191 DOI: 10.1002/da.22389] [Citation(s) in RCA: 144] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Revised: 03/31/2015] [Accepted: 05/19/2015] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Individual randomized controlled trials (RCTs) have demonstrated the efficacy of cognitive behavioral therapy (CBT) and serotonin reuptake inhibitors (SRIs) for the treatment of youth with obsessive-compulsive disorder (OCD). Although meta-analyses have confirmed these results, there has been minimal examination of treatment moderators or an examination of treatment response and symptom/diagnostic remission for these two treatment types. The present report examined the treatment efficacy, treatment response, and symptom/diagnostic remission for youth with OCD receiving either CBT or SRIs relative to comparison conditions, and examined treatment moderators. METHOD A comprehensive literature search identified 20 RCTs that met inclusion criteria, and produced a sample size of 507 CBT participants and 789 SRI participants. RESULTS Random effects meta-analyses of CBT trials found large treatment effects for treatment efficacy (g = 1.21), treatment response (relative risk [RR] = 3.93), and symptom/diagnostic remission (RR = 5.40). Greater co-occurring anxiety disorders, therapeutic contact, and lower treatment attrition were associated with greater CBT effects. The number needed to treat (NNT) was three for treatment response and symptom/diagnostic remission. Random effects meta-analyses of SRI trials found a moderate treatment effect for treatment efficacy (g = 0.50), treatment response (RR = 1.80), and symptom/diagnostic remission (RR = 2.06). Greater methodological quality was associated with a lower treatment response for SRI trials. The NNT was five for treatment response and symptom/diagnostic remission. CONCLUSIONS Findings demonstrate the treatment effects for CBT and SRIs across three important outcome metrics, and provide evidence for moderators of CBT across trials.
