Comparing the efficacy of pharmacological and psychological treatment, alone and in combination, in children and adolescents with obsessive-compulsive disorder: A network meta-analysis

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.

Comparison of internet-based and face-to-face cognitive behavioral therapy for obsessive-compulsive disorder: A systematic review and network meta-analysis

Cognitive behavioral therapy (CBT) is widely recognized as an effective treatment for obsessive-compulsive disorder (OCD). However, few patients are able to receive CBT. Internet-based CBT (ICBT) may be able to overcome this problem. In this study, we aimed to compare the efficacy of CBT, therapist-guided ICBT (TG-ICBT), unguided ICBT (UG-ICBT), and none therapist-guided ICBT (NTG-ICBT) by a network meta-analysis. The primary outcome was the mean change in OCD severity measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) or the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). The secondary outcomes included the severity of depressive symptoms, side effects, and cost-effectiveness. A total of 25 trials with 1642 participants were included. We found that the efficacy of CBT was superior to that of TG-ICBT. The mean improvement in Y-BOCS/CY-BOCS scores was higher in CBT group than in UG-ICBT group, but this difference was not statistically significant. The efficacy did not differ significantly between TG-ICBT and UG-ICBT. CBT, TG-ICBT, and UG-ICBT were all more effective than the psychological placebo, waiting list, and pill placebo. In terms of efficacy, CBT combined with drug therapy was better than CBT, TG-ICBT, and UG-ICBT. Sensitivity analyses supported these findings. Based on the current evidence, we recommend TG-ICBT when CBT is not available. However, it is undeniable that UG-ICBT also has the potential to be an effective alternative to CBT. More evidence is needed to support this possibility.

Economic Analyses of Obsessive-Compulsive Disorder Interventions: A Systematic Review

BACKGROUND

Obsessive-compulsive disorder (OCD) is a neuropsychiatric condition featuring patterns of obsessions, compulsions, and avoidant behaviors that are often time consuming and distressing to affected individuals. Cognitive-behavioral therapy (CBT) with exposure and response prevention and/or serotonin reuptake inhibitors are first-line treatments for OCD, though other therapeutic interventions may serve as economically practical modalities under various circumstances. Exploring and understanding the cost effectiveness of all indicated OCD interventions are important to inform therapeutic decisions and provide quality patient-centered care at a cost that is not burdensome to the patient and/or healthcare system.

METHODS

A systematic literature review was performed and studies were extracted from PubMed, Embase, Ovid MEDLINE, and Cochrane. All cost-effectiveness studies that included economic analyses with respect to OCD treatment modalities and were written in English and published between January 2010 and July 2022 were eligible for inclusion in the present study. We report a narrative synthesis of the findings and quality appraisal of the selected references.

RESULTS

Of the 707 references returned in the literature search, a total of 18 cost-effectiveness studies were included for review. Compared with treatment as usual, several studies reported clinical superiority and cost effectiveness of Internet-based CBT programs for adults and children with OCD at various willingness-to-pay thresholds and economic reference indicators, though cost effectiveness relative to in-person CBT with exposure and response prevention is unclear and estimates of efficacy are likely lower for Internet-based CBT. One study favored the cost utility of serotonin reuptake inhibitor monotherapy over CBT with exposure and response prevention although efficacy estimates of the former tend to be lower, and relative cost differences were low. Five studies evaluated the cost effectiveness of high-intensity neuroaugmentation, including deep brain stimulation and stereotactic radiosurgical capsulotomy, in the context of treatment-refractory OCD.

CONCLUSIONS

Despite the relatively high prevalence of OCD worldwide, cost-effectiveness data for therapeutic modalities remain sparse. Because of the chronic nature of OCD, the cost of treatment accumulates and may lead to a significant financial burden over time, particularly when non-evidence-based interventions are used. However, several alternative therapeutic modalities hold promise for economic practicality without significant sacrifice in clinical efficacy. Future studies are necessary to directly compare the cost effectiveness of such therapeutic alternatives with the current standard of care, CBT with exposure and response prevention.

Early Identification and Intervention in Pediatric Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a psychiatric disorder characterized by persistent thoughts with subsequent repetitive behaviors. Interventions that are effective for adult OCD cannot simply be generalized to pediatric OCD, since OCD in children and adolescents usually has a different clinical presentation, etiology and course from adult OCD. Delayed and inadequate treatment is associated with a worse prognosis, making the need for early identification and intervention in pediatric OCD very urgent. In this paper, we reflected on the current constraints that make early interventions for pediatric OCD unpromoted and reviewed the approaches with potential application for early identification and early intervention in pediatric OCD, categorized by three-level prevention stages corresponding to a clinical staging model. Since the etiology of pediatric OCD is still unclear, primary prevention is most lacking, and early interventions for pediatric OCD are currently focused on the secondary prevention stage, which aims to prevent the conversion of obsessive-compulsive symptoms into full-blown OCD; tertiary prevention mostly focuses on the alleviation of mild to moderate OCD, while interventions for co-morbidities are still in their infancy. We closed by considering the important research questions on this topic.
