Psychological Treatment of Obsessive-Compulsive Disorder in Children and Adolescents: a Meta-Analysis

Advances in Pediatric Obsessive-Compulsive Disorder (OCD) Treatment: A Comprehensive Narrative Review

Obsessive-compulsive disorder (OCD), characterized by persistent, intrusive thoughts (obsessions) and repetitive behaviors or mental acts (compulsions), can significantly impact a child's daily functioning, academic performance, and overall quality of life. As the prevalence of pediatric OCD continues to rise, there is a critical demand for evidence-based treatments that not only alleviate symptoms but also enhance the quality of life for affected children and adolescents. By identifying gaps in knowledge and suggesting directions for future research, this narrative review contributes to the ongoing discourse on pediatric OCD treatments. Ultimately, the synthesis of evidence aims to enhance our understanding and inform best practices in the compassionate and effective management of OCD in children and adolescents. The aim of this study is to provide a comprehensive overview of current trends and emerging strategies in the treatment of pediatric obsessive-compulsive disorder (OCD) and highlights the significance of tailoring treatment approaches to individual patient needs, considering factors such as symptom severity and treatment response. Concentrating on interventions supported by empirical evidence, the review delves into cognitive-behavioral therapy (CBT), pharmacotherapy, the synergistic effects of these modalities, and inventive therapeutic approaches, all while considering the distinctive developmental aspects pertinent to pediatric populations. We conducted this review by searching for titles in the PubMed database from 2013 to present. Our comprehensive literature review focused on advancements in treating pediatric OCD, using keywords like "Obsessive-compulsive disorder," "Pediatric," "treatment," "CBT," "SSRI," "Pharmacotherapy," and "combination therapy." While both pharmacotherapy and CBT show individual efficacy, the combination of these approaches appears to be more effective, especially for medication non-responders with no prior exposure to CBT, despite some mixed findings. These findings contribute significantly to the ongoing discussion on optimizing combined therapy strategies tailored to the complexities of pediatric OCD.

Internet-Based Cognitive Behavioural Treatments for Obsessive-Compulsive Disorder: A Systematic Review and Meta-Analysis

Obsessive-compulsive disorder (OCD) is a common mental health condition characterized by distressing, intrusive thoughts (obsessions) and repetitive behaviours (compulsions) aimed at reducing anxiety. Internet-based cognitive behavioural therapy (ICBT) has emerged as an effective treatment modality for various mental health disorders. This meta-analysis evaluates the efficacy of guided self-help ICBT (GSH ICBT) and unguided self-help ICBT (SH ICBT) against active and passive control conditions in adults with OCD. A comprehensive systematic literature search yielded 12 randomized controlled trials (RCTs) comprising 15 comparison arms (N = 1416) that met the inclusion criteria. Results indicate that GSH ICBT significantly reduced OCD symptomatology posttreatment compared to active controls (g = 0.378, k = 9), with no significant effects maintained at follow-up (g = 0.153, k = 4). GSH ICBT was also found to be as effective as active CBT interventions in reducing comorbid anxiety and depression symptoms posttreatment (g = 0.278, k = 6) and at follow-up (g = 0.124, k = 4). However, improvements in quality of life were not significant posttreatment (g = 0.115, k = 4) nor at follow-up (g = 0.179, k = 3). Combined GSH and SH ICBT demonstrated large effects on reducing OCD symptoms (g = 0.754, k = 6), medium effects on comorbid symptoms (g = 0.547, k = 6) and small effects on quality of life (g = 0.227, k = 2) when compared to inactive controls. No significant differences were found between GSH and SH ICBT in all measured outcomes posttreatment (OCD: g = 0.098, k = 3; AD: g = 0.070, k = 3; QoL: g = -0.030, k = 1) and at follow-up (OCD: g = 0.265, k = 2; AD: g = 0.084, k = 2; QoL: g = 0.00, k = 1). Sample size was identified as a significant moderator of treatment effects. This paper further explores clinical significance, treatment adherence, therapist time investment and moderator influences of the ICBT. The limitations of the study and recommendations for future research are thoroughly discussed.

Efficacy and acceptability of cognitive-behavioral therapy and serotonin reuptake inhibitors for pediatric obsessive-compulsive disorder: a network meta-analysis

BACKGROUND

Cognitive-behavioral therapy (CBT) and serotonin reuptake inhibitors (SRIs) are recommended treatments for pediatric obsessive-compulsive disorder (OCD), but their relative efficacy and acceptability have not been comprehensively examined. Further, it remains unclear whether the efficacy of in-person CBT is conserved when delivered in other formats, such as over telephone/webcam or as Internet-delivered CBT (ICBT).

METHODS

PubMed, PsycINFO, trial registries, and previous systematic reviews were searched for randomized controlled trials (RCTs) comparing CBT (in-person, webcam/telephone-delivered, or ICBT) or SRIs with control conditions or each other. Network meta-analyses were conducted to examine efficacy (post-treatment Children's Yale-Brown Obsessive Compulsive Scale) and acceptability (treatment discontinuation). Confidence in effect estimates was evaluated with CINeMA (Confidence in Network Meta-Analysis).

RESULTS

Thirty eligible RCTs and 35 contrasts comprising 2,057 youth with OCD were identified. In-person CBT was significantly more efficacious than ICBT, waitlist, relaxation training, and pill placebo (MD range: 3.95-11.10; CINeMA estimate of confidence: moderate) but did not differ significantly from CBT delivered via webcam/telephone (MD: 0.85 [-2.51, 4.21]; moderate), SRIs (MD: 3.07 [-0.07, 6.20]; low), or the combination of in-person CBT and SRIs (MD: -1.20 [-5.29, 2.91]; low). SRIs were significantly more efficacious than pill placebo (MD: 4.59 [2.70, 6.48]; low) and waitlist (MD: 8.03 [4.24, 11.82]; moderate). No significant differences for acceptability emerged, but confidence in estimates was low.

CONCLUSIONS

In-person CBT and SRIs produce clear benefits compared to waitlist and pill placebo and should be integral parts of the clinical management of pediatric OCD, with in-person CBT overall having a stronger evidence base. The combination of in-person CBT and SRIs may be most efficacious, but few studies hinder firm conclusions. The efficacy of CBT appears conserved when delivered via webcam/telephone, while more trials evaluating ICBT are needed.

Obsessional intrusive thoughts in children: An interview based study

OBJECTIVES

We aimed to investigate the experience of obsessional intrusive thoughts (OITs) in a sample of children aged 8 to 10 years old and to test the main tenets of the cognitive model of OCD. Specifically, we assessed: (1) the prevalence of OITs experienced by young children; (2) their frequency and content; (3) the emotions they evoke; (4) the reasons why they are upsetting; (5) how they are appraised (6) and what control strategies they use.

METHODS

Forty-nine children (28 girls, 21 boys; mean age 9.1 years) from the community completed two self-report questionnaires assessing anxiety and obsessive-compulsive symptoms. Children were interviewed using the Children's Anxious Thoughts Interview, which assessed their experiences of OITs.

RESULTS

From the 49 participants, 71.43% reported having experienced at least one OIT. The most frequent contents related to harm and doubt. Of the total sample, 28.6% reported having experienced one OIT recently with at least moderate frequency; these participants reported higher anxiety and obsessive-compulsive interference, described feeling nervous and anxious when experiencing their OIT, and rated their OIT as highly important and distracting. The most frequently reported control strategies were cognitive - suppression, distraction and thought replacement.

CONCLUSIONS

Almost two thirds of community children reported experiencing OITs. The findings from this study provide preliminary support for the application of the cognitive model of OCD in children. Subtle differences from previous research with adults are discussed.

Change Patterns During Family-Based Treatment for Pediatric Obsessive Compulsive Disorder

Cognitive behavior therapy (CBT) for young people with obsessive compulsive disorder (OCD) has recently been enhanced to target family environment factors. However, the process of change for OCD symptoms and family factors during treatment is not well understood. Uniquely, we explored patterns of change for OCD symptoms and a range of family variables throughout Baseline, Early, Mid, and Late treatment phases of family-based CBT (FCBT) for 15 young people with OCD using multiple informants. We predicted a linear reduction in OCD symptom severity and family accommodation (FA) across treatment phases, however the investigation into other family factor change patterns was exploratory. OCD symptom severity, FA, parental distress tolerance (DT), and conflict all showed significant linear change patterns across treatment phases according to multiple informants. In addition, the largest proportion of change for these variables typically occurred during the first third of treatment, highlighting the importance of identifying participants with and without early gains in future research. Blame also showed a significant linear change pattern, although with small reductions between treatment phases. Preliminary bivariate analyses sought to better understand whether family factor change predicted subsequent OCD severity change or vice versa. Similar patterns emerged across informants, including identification of OCD severity as a significant predictor of change for Blame at subsequent treatment phases. Analyses also showed bi-directional effects for DT and OCD symptoms across informants, where DT predicted OCD severity at subsequent treatment phases and vice versa. These outcomes support further research aimed at understanding the role of family factors in pediatric OCD symptom change.

Psychoeducation focused on family accommodation: a practical intervention for parents of children and adolescents with obsessive-compulsive disorder

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.

Cognitive-Behavioral Therapy for Obsessive-Compulsive Disorder: 2021 Update

In this update of a previous review, the authors discuss cognitive-behavioral therapy (CBT) with exposure and response prevention for obsessive-compulsive disorder (OCD). This efficacious modality avoids side effects common to psychotropic medication and reduces risk of relapse once treatment has ended. Psychotherapy involves identification and ranking of stimuli that provoke obsessions, exposure to these stimuli while preventing compulsions, and cognitive restructuring. The family of the OCD patient plays a significant role in treatment. This article includes expanded research on family-focused CBT and treatment of pediatric OCD. The family's accommodation and emotional response to a patient's symptoms may interfere with therapy and perpetuate the disorder. The treatment of pediatric OCD involves the same considerations. However, the form of obsessions and compulsions may differ and therapeutic techniques are modified to make them age appropriate.

Internet-based cognitive behavioral therapy in children and adolescents with obsessive compulsive disorder: a feasibility study

Cognitive behavioral therapy (CBT) is the first choice of treatment of obsessive–compulsive disorder (OCD) in children and adolescents. However, there is often a lack of access to appropriate treatment close to the home of the patients. An internet-based CBT via videoconferencing could facilitate access to state-of-the-art treatment even in remote areas. The aim of this study was to investigate feasibility and acceptability of this telemedical approach. A total of nine children received 14 sessions of CBT. The first session took place face-to-face, the remaining 13 sessions via videoconference. OCD symptoms were recorded with a smartphone app and therapy materials were made accessible in a data cloud. We assessed diagnostic data before and after treatment and obtained measures to feasibility, treatment satisfaction and acceptability. Outcomes showed high acceptance and satisfaction on the part of patients with online treatment (89%) and that face-to-face therapy was not preferred over an internet-based approach (67%). The majority of patients and their parents classified the quality of treatment as high. They emphasized the usefulness of exposures with response prevention (E/RP) in triggering situations at home. The app itself was rated as easy to operate and useful. In addition to feasibility, a significant decrease in obsessive–compulsive symptoms was also achieved. Internet-based CBT for pediatric OCD is feasible and well received by the patients and their parents. Furthermore, obsessive–compulsive symptomatology decreased in all patients. The results of this study are encouraging and suggest the significance of further research regarding this technology-supported approach, with a specific focus on efficacy.

Altered fronto-amygdalar functional connectivity predicts response to cognitive behavioral therapy in pediatric obsessive-compulsive disorder

BACKGROUND

Based on findings from adults with obsessive-compulsive disorder (OCD), this study examined alterations in resting-state functional connectivity (rs-fc) between the basolateral amygdala (BLA) and the ventromedial prefrontal cortex (vmPFC) in children and adolescents with OCD. We also assessed whether such BLA-vmPFC connectivity changed with or predicted response to exposure and response prevention (E/RP), the first-line treatment for pediatric OCD, given the involvement of these regions in fear processing, regulation, and extinction learning-a probable mechanism of action of E/RP.

METHODS

Resting state functional magnetic resonance imaging scans were acquired from 25 unmedicated, treatment-naïve pediatric patients with OCD (12.8 ± 2.9 years) and 23 age- and sex-matched healthy controls (HCs; 11.0 ± 3.3 years). Patients completed a 12-16-week E/RP intervention for OCD. Participants were rescanned after the 12-16-week period. ANCOVAs tested group differences in baseline rs-fc. Cross-lagged panel models examined relationships between BLA-vmPFC rs-fc and OCD symptoms pre- and posttreatment. All tests were adjusted for participants' age, sex, and head motion.

RESULTS

Right BLA-vmPFC rs-fc was significantly reduced (more negative) in patients with OCD relative to HCs at baseline, and increased following treatment. In patients, more positive (less negative) right BLA-vmPFC rs-fc pretreatment predicted greater OCD symptoms reduction posttreatment. Changes in BLA-vmPFC rs-fc was unassociated with change in OCD symptoms pre- to posttreatment.

CONCLUSIONS

These results provide further evidence of the BLA-vmPFC pathway as a potential target for novel treatments or prevention strategies aimed at facilitating adaptive learning and fear extinction in children with OCD or subclinical OCD symptoms.

An Observational Study of OCD Patients Treated With Cognitive Behavioral Therapy During the COVID-19 Pandemic

Background and Objectives: While the consequences of the COVID-19 pandemic for general mental health and the increase in anxiety and depression are clear, less is known about the potential effect of the pandemic on OCD. The purpose of this study is to collect new data to monitor the symptomatic status of patients with OCD during the period of emergency due to COVID-19 and to make a comparison between two psychodiagnostic evaluations. Methods: Eleven OCD patients and their psychotherapists were recruited. All patients had a specific psychodiagnostic assessment for OCD (SCL-90; OCI-R; Y-BOCS self-report) performed between December 2019 and January 2020 (t0), and undertook cognitive behavioral therapy (CBT) and exposure and prevention of response protocol (ERP) before the lockdown. The psychodiagnostic assessment carried out at t0 was re-administered (t1) to all patients, together with a set of qualitative questions collected through an online survey. The respective therapists were asked to document the status of the therapy and the monitoring of symptoms through use of a semi-structured interview (Y-BOCS) and a qualitative interview. Non-parametric analyses were conducted. Results: Patients reported a significant decrease in OCD symptoms. Data analysis showed a decrease in the scores across t0 and at t1 on the Y-BOCS (SR) total self-report, and on OCD symptoms' severity assessed by means of the OCI-r and SCL-90 r OC subscale, for 11 participants. Relating to the measures detected by psychotherapists, marginally significant improvements and lower scores were found in the Y-BOCS (I). An improvement in symptoms was noticed by 90.9% of the clinical sample; this was confirmed by 45.4% of the therapists, who claimed moderate progress in their patients. Conclusions: The data collected through standardized measurements at two different times, albeit relative to a small sample, assume relevance from a clinical point of view. In the literature, some studies document the worsening of OCD. However, in many studies, the type of treatment, the detection time, and the intervention period are not well-specified. These results confirm the effectiveness of CBT/ERP as an elective treatment for OCD through a specific intervention procedure.

The Psychopharmacology of Obsessive-Compulsive Disorder: A Preclinical Roadmap

This review evaluates current knowledge about obsessive-compulsive disorder (OCD), with the goal of providing a roadmap for future directions in research on the psychopharmacology of the disorder. It first addresses issues in the description and diagnosis of OCD, including the structure, measurement, and appropriate description of the disorder and issues of differential diagnosis. Current pharmacotherapies for OCD are then reviewed, including monotherapy with serotonin reuptake inhibitors and augmentation with antipsychotic medication and with psychologic treatment. Neuromodulatory therapies for OCD are also described, including psychosurgery, deep brain stimulation, and noninvasive brain stimulation. Psychotherapies for OCD are then reviewed, focusing on behavior therapy, including exposure and response prevention and cognitive therapy, and the efficacy of these interventions is discussed, touching on issues such as the timing of sessions, the adjunctive role of pharmacotherapy, and the underlying mechanisms. Next, current research on the neurobiology of OCD is examined, including work probing the role of various neurotransmitters and other endogenous processes and etiology as clues to the neurobiological fault that may underlie OCD. A new perspective on preclinical research is advanced, using the Research Domain Criteria to propose an adaptationist viewpoint that regards OCD as the dysfunction of a normal motivational system. A systems-design approach introduces the security motivation system (SMS) theory of OCD as a framework for research. Finally, a new perspective on psychopharmacological research for OCD is advanced, exploring three approaches: boosting infrastructure facilities of the brain, facilitating psychotherapeutic relearning, and targeting specific pathways of the SMS network to fix deficient SMS shut-down processes. SIGNIFICANCE STATEMENT: A significant proportion of patients with obsessive-compulsive disorder (OCD) do not achieve remission with current treatments, indicating the need for innovations in psychopharmacology for the disorder. OCD may be conceptualized as the dysfunction of a normal, special motivation system that evolved to manage the prospect of potential danger. This perspective, together with a wide-ranging review of the literature, suggests novel directions for psychopharmacological research, including boosting support systems of the brain, facilitating relearning that occurs in psychotherapy, and targeting specific pathways in the brain that provide deficient stopping processes in OCD.

Altered network connectivity predicts response to cognitive-behavioral therapy in pediatric obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is commonly associated with alterations in cortico-striato-thalamo-cortical brain networks. Yet, recent investigations of large-scale brain networks suggest that more diffuse alterations in brain connectivity may underlie its pathophysiology. Few studies have assessed functional connectivity within or between networks across the whole brain in pediatric OCD or how patterns of connectivity associate with treatment response. Resting-state functional magnetic resonance imaging scans were acquired from 25 unmedicated, treatment-naive children and adolescents with OCD (12.8 ± 2.9 years) and 23 matched healthy control (HC) participants (11.0 ± 3.3 years) before participants with OCD completed a course of cognitive-behavioral therapy (CBT). Participants were re-scanned after 12-16 weeks. Whole-brain connectomic analyses were conducted to assess baseline group differences and group-by-time interactions, corrected for multiple comparisons. Relationships between functional connectivity and OCD symptoms pre- and post-CBT were examined using longitudinal cross-lagged panel modeling. Reduced connectivity in OCD relative to HC participants was detected between default mode and task-positive network regions. Greater (less altered) connectivity between left angular gyrus and left frontal pole predicted better response to CBT in the OCD group. Altered connectivity between task-positive and task-negative networks in pediatric OCD may contribute to the impaired control over intrusive thoughts early in the illness. This is the first study to show that altered connectivity between large-scale network regions may predict response to CBT in pediatric OCD, highlighting the clinical relevance of these networks as potential circuit-based targets for the development of novel treatments.

Family involvement and treatment for young children with Obsessive-Compulsive Disorder: Randomized control study

BACKGROUND/OBJECTIVE

The aim of this paper was to evaluate the diferential efficacy of cognitive behavioral family treatment in children under 8 years of age with Obsessive-Compulsive Disorder (OCD) in the reduction of obsessive-compulsive responses and secondary outcomes in three treatment conditions: (a) Treatment of parents and child, (b) Treatment of mother and child, and (c) Treatment of mother.

METHOD

Forty-four children with obsessive-compulsive disorder, aged 5.2-7.9 years old and their parents, were randomized to one of three groups in a 1:1:1 ratio. Seventy-five percent was male and 100% Caucasian (White-European). Treatment involved 12 individual sessions of is Cognitive-Behavioral Family-Based Treatment delivered.

RESULTS

The three conditions produced clinical improvements in post-test and follow-up in the primary (symptom severity OCD) and secondary outcomes. The results showed no intergroup differences in variables related to OCD symptom severity, although statistically significant differences were found in groups in Internalizing and Externalizing problem, mother and fathers accomodation.

CONCLUSIONS

The most efficient condition was that including a greater number of family members even when there was high family accommodation. The direct involvement of the child in the psychological treatment was important in achieving better results.

Obsessive compulsive disorder (OCD): Current treatments and a framework for neurotherapeutic research

We briefly review current approaches to the diagnosis and treatment of OCD, noting their lack of a strong theoretical foundation. In keeping with the Research Domain Criteria project (RDoC) calls for reconceptualizing psychopathology in ways that better link up with normal brain systems, we advance an adaptationist, brain-network perspective on OCD and propose that OCD represents a dysfunction in the stopping dynamics of a normal brain network that evolved to handle potential danger. We then illustrate how this theoretical perspective can be used to organize possibilities for research on neurotherapeutics for OCD and suggest novel directions for future work.

Comorbidity, Parental Psychopathology, and Accommodation in the Treatment of Pediatric Obsessive-Compulsive Disorder: A Case Study

This article discusses the treatment of a young person with obsessive-compulsive disorder (OCD) characterized primarily by symptoms of physical and mental contamination, as well as religious obsessions. The treatment was complicated by several factors that will be reviewed and addressed. First, this client had a comorbid diagnosis of attention-deficit/hyperactivity disorder. Second, the young client's mother was also diagnosed with OCD and had a significantly anxious presentation. This impacted treatment in two primary ways. One important way treatment was complicated was that the client frequently attempted to manage her mother's emotions by underreporting her own distress at times. The other implication of the mother's diagnosis was that it became difficult to involve her in the treatment of her daughter and reduce her accommodation of her daughter's symptoms. The manner in which these complicating factors were addressed in the successful treatment of this client by adapting evidence-based practice will be presented as a guide for clinicians facing similar challenges.

Predictors of treatment outcome for youth receiving intensive residential treatment for obsessive-compulsive disorder (OCD)

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.

Challenges in the diagnosis and treatment of pediatric obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) affects 1%-3% of children worldwide and has a profound impact on quality of life for patients and families. Although our understanding of the underlying etiology remains limited, data from neuroimaging and genetic studies as well as the efficacy of serotonergic medications suggest the disorder is associated with the fundamental alterations in the function of cortico-striato-thalamocortical circuits. Significant delays to diagnosis are common, ultimately leading to more severe functional impairment with long-term developmental consequences. The clinical assessment requires a detailed history of specific OCD symptoms as well as psychiatric and medical comorbidities. Standardized assessment tools may aid in evaluating and tracking symptom severity and both individual and family functioning. In the majority of children, an interdisciplinary approach that combines cognitive behavioral therapy with a serotonin reuptake inhibitor leads to meaningful symptom improvement, although some patients experience a chronic, episodic course. There are limited data to guide the management of treatment-refractory illness in children, although atypical antipsychotics and glutamate-modulating agents may be used cautiously as augmenting agents. This review outlines a clinical approach to the diagnosis and management of OCD, highlighting associated challenges, and limitations to our current knowledge.

Obsessive-compulsive symptom dimensions: Association with comorbidity profiles and cognitive-behavioral therapy outcome in pediatric obsessive-compulsive disorder

Our aims were to examine: (1) classes of comorbid disorders in a sample of children and adolescents with Obsessive-Compulsive Disorder (OCD), (2) how these classes relate to obsessive-compulsive symptom dimensions, and (3) the extent to which obsessive-compulsive symptom dimensions predict Cognitive-Behavioral Therapy (CBT) outcome. Participants (N = 269) were assessed with the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL) and the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). Latent Class Analysis (LCA) was used to identify comorbidity classes. Regression analyses were used to evaluate symptom dimensions as predictors of treatment outcome and their relation to comorbidity classes. Comorbidity was included in the treatment outcome analyses as it can affect outcome. Comorbidity was best categorized by a three-class model and each class was distinctively correlated with the OCD symptom dimensions. Higher scores on the symmetry/hoarding factor increased the chance of responding to CBT by an odds ratio of 1.56 (p = 0.020) when controlled for age, gender, and comorbidity class. The harm/sexual factor (p = 0.675) and contamination/cleaning factor (p = 0.122) did not predict CBT outcome. Three clinically relevant comorbidity subgroups in pediatric OCD were identified. Patients who exhibited higher levels of symmetry/hoarding dimension were more prone to respond to CBT.

An Initial Case Series of Intensive Cognitive-Behavioral Therapy for Obsessive-Compulsive Disorder in Adolescents with Autism Spectrum Disorder

Obsessive-compulsive disorder (OCD) is prevalent among youth with autism spectrum disorder (ASD). Cognitive-behavioral therapy (CBT) with ASD-specific modifications has support for treating OCD in this population; however, use of intensive CBT in youth with ASD and severe OCD has not been tested. The current study examined the preliminary effectiveness of an individualized intensive CBT protocol for OCD in adolescents with ASD. Nine adolescents (aged 11-17 years) completed a regimen of intensive CBT (range 24-80 daily sessions) incorporating exposure with response prevention (ERP). Treatment materials, language and techniques were modified in accordance with evidence-based findings for this population. Seven of nine participants (78%) were treatment responders, and large treatment effects (d = 1.35-2.58) were obtained on primary outcomes (e.g., obsessive-compulsive symptom severity). Preliminary findings suggest that an intensive CBT approach for OCD is effective among adolescents with ASD.

Mechanisms of cognitive-behavioral therapy for obsessive-compulsive disorder involve robust and extensive increases in brain network connectivity

Cognitive-behavioral therapy (CBT) is effective for obsessive compulsive disorder (OCD); however, little is understood about its mechanisms related to brain network connectivity. We examined connectivity changes from resting-state functional magnetic resonance imaging data pre-to-post-CBT in 43 OCD participants, randomized to receive either 4 weeks of intensive CBT or 4 weeks waitlist followed by 4 weeks of CBT, and 24 healthy controls before and after 4 weeks of no treatment. Network-based-statistic analysis revealed large-magnitude increases in OCD connectivity in eight networks. Strongest increases involved connectivity between the cerebellum and caudate/putamen, and between the cerebellum and dorsolateral/ventrolateral prefrontal cortices. Connectivity increases were associated with increased resistance to compulsions. Mechanisms of CBT may involve enhanced cross-network integration, both within and outside of classical cortico-striatal-thalamo-cortical regions; those involving cerebellar to striatal and prefrontal regions may reflect acquisition of new non-compulsive goal-directed behaviors and thought patterns. Our findings have implications for identifying targets for enhancing treatment efficacy and monitoring treatment progress.

Cognitive-behavioral high parental involvement treatments for pediatric obsessive-compulsive disorder: A meta-analysis

A meta-analysis on the efficacy of cognitive-behavior-family treatment (CBFT) on children and adolescents with obsessive-compulsive disorder (OCD) was accomplished. The purposes of the study were: (a) to estimate the effect magnitude of CBFT in ameliorating obsessive-compulsive symptoms and reducing family accommodation on pediatric OCD and (b) to identify potential moderator variables of the effect sizes. A literature search enabled us to identify 27 studies that fulfilled our selection criteria. The effect size index was the standardized pretest-postest mean change index. For obsessive-compulsive symptoms, the adjusted mean effect size for CBFT was clinically relevant and statistically significant in the posttest (d_adj=1.464). For family accommodation the adjusted mean effect size was also positive and statistically significant, but in a lesser extent than for obsessive-compulsive symptoms (d_adj=0.511). Publication bias was discarded as a threat against the validity of the meta-analytic results. Large heterogeneity among effect sizes was found. Better results were found when CBFT was individually applied than in group (d₊=2.429 and 1.409, respectively). CBFT is effective to reduce obsessive-compulsive symptoms, but offers a limited effect for family accommodation. Additional modules must be included in CBFT to improve its effectiveness on family accommodation.

Pediatric obsessive-compulsive disorder with tic symptoms: clinical presentation and treatment outcome

Some studies have shown that children and adolescents with obsessive-compulsive disorder (OCD) and co-morbid tics differ from those without co-morbid tics in terms of several demographic and clinical characteristics. However, not all studies have confirmed these differences. This study examined children and adolescents with OCD and with possible or definite tic specifiers according to the DSM-5 in order to see whether they differ from patients without any tic symptoms regarding clinical presentation and outcome of cognitive behavioral therapy (CBT). The full sample included 269 patients (aged 7-17) with primary DSM-IV OCD who had participated in the Nordic Long-term Treatment Study (NordLOTS). Symptoms of tics were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL). One or more tic symptoms were found in 29.9% of participants. Those with OCD and co-morbid tic symptoms were more likely male, more likely to have onset of OCD at an earlier age, and differed in terms of OCD symptom presentation. More specifically, such participants also showed more symptoms of OCD-related impairment, externalization, autism spectrum disorder (ASD), social anxiety, and attention-deficit/hyperactivity disorder (ADHD). However, the two groups showed no difference in terms of OCD severity or outcome of CBT. Children and adolescents with OCD and co-morbid tic symptoms differ from those without tic symptoms in several aspects of clinical presentation, but not in their response to CBT. Our results underscore the effectiveness of CBT for tic-related OCD.

Obsessive-Compulsive Disorder in Paediatric and Adult Samples: Nature, Treatment and Cognitive Processes. A Review of the Theoretical and Empirical Literature

The appraisal model of obsessive-compulsive disorder (OCD) suggests that six key appraisal domains contribute to the aetiology and maintenance of OCD symptoms. An accumulating body of evidence supports this notion and suggests that modifying cognitive appraisals may be beneficial in reducing obsessive-compulsive symptomatology. This literature review first summarises the nature of OCD and its treatment, followed by a summary of the existing correlational and experimental research on the role of cognitive appraisal processes in OCD across both adult and paediatric samples. While correlational data provide some support for the relationship between cognitive appraisal domains and OCD symptoms, results are inconclusive, and experimental methods are warranted to determine the precise causal relationship between specific cognitive appraisal domains and OCD symptoms.

Measurement Issues: The measurement of obsessive compulsive disorder in children and young people in clinical practice

BACKGROUND

If left untreated, obsessive compulsive disorder (OCD) can cause significant distress and impact on functioning throughout the lifespan. Despite the severity of the disorder, there is often a significant delay between the onset of symptoms and successful treatment. This is in part due to delays in recognising OCD symptoms in young people, particularly if the symptom forms are less common. Once OCD is accurately diagnosed, cognitive behavioural therapy (CBT) is known to be an efficacious treatment, sometimes in combination with medication, producing good long-term prognosis. It is therefore important to accurately detect OCD in children and young people so that they can be offered timely intervention. Use of the best tools in clinical and research settings improves detection and diagnosis, as well as enabling the tracking of progress through treatment. The aim of this current paper was to review measurement tools for OCD in young people with a focus on the practicalities of using tools in busy child mental health clinical settings.

To discover what measurement tools are available for OCD in young people, we conducted a pragmatic literature of measurement tools for OCD in young people. We searched PsycINFO, Med-Line and the Cochrane databases for reports relating to the measurement of OCD. Additionally, we sought information from the National Institute for Health and Care Excellence (NICE) guidance, the Child Outcomes Research Consortium (CORC) website and the Children and Young People's Improving Access to Psychological Therapies (CYP IAPT) Programme. We also reviewed large trials and meta-analyses of the treatment of OCD in young people and communicated with relevant researchers/clinicians.

RESULTS

Seventeen questionnaire measurement tools, with variable psychometric properties, and four commonly used semistructured clinician administered interview measures were identified.

CONCLUSIONS

There are several measurement tools with good psychometric properties that are useful for initial screening/identification of OCD, as well as formal diagnosis, symptom tracking and treatment evaluation. With the availability of brief screens, as well as online diagnostic measures, such tools should not be a burden on clinical practice, but rather a helpful aid to support clinicians' assessment and treatment of OCD.

A preliminary study of cognitive-behavioral family-based treatment versus parent training for young children with obsessive-compulsive disorder

BACKGROUND

Cognitive-Behavioral Family-Based Treatment (CBFT) is the standard of care in young children with OCD. Developmental considerations, parent desires, and cost-effective advantages motivate research to explore the relative efficacy of parent-only interventions. The main goal in this study was to test the effectiveness and feasibility of a parent only intervention for OCD in young children, comparing, in a preliminary fashion the relative efficacy of reducing obsessive-compulsive symptoms through two treatment conditions: 1) an individual CBFT for early OCD involving both parents and children, and 2) the family component of the intervention involving only individual Parent Training (PT).

METHODS

Twenty treatment-seeking families from two private outpatient clinics in Spain were alternately assigned to one of the two treatment conditions. Participants had a primary diagnosis of OCD and a mean age of 6.62 years (65% males). Interventions were conducted by the same therapist and the assessments were administered by independent clinicians who were blind to the experimental conditions of the participants. Assessment time-points were pretreatment, posttreatment, and 3-month follow-up (including diagnosis, symptom severity, global functioning, family accommodation, externalizing and internalizing symptoms, and satisfaction measures).

RESULTS

The two ways of implementation, involving child and parents (CBFT) or involving only parents (PT), produced clinical improvements and were well-accepted by parents and children. The CBFT condition was superior to the PT condition in reducing externalizing problems.

LIMITATIONS

reduced sample size and absence of randomization were the main limitations of this study.

CONCLUSIONS

these results suggest, in a preliminary manner, that the need to have the child present at session with the clinician could be decreased for some children, as well as the overall feasibility of working only with parents for the implementation of CBT for OCD in very young children.
