ABSTRACT
Objective: To evaluate the effectiveness of group cognitive-behavioral therapy (GCBT) for the treatment of adolescents with obsessive compulsive disorder (OCD). Methods: This review was registered in PROSPERO under number CRD42020158475. Five databases (PubMed, Virtual Health Library, Web of Science, Scopus, and PsycINFO) were searched. After applying the inclusion and exclusion criteria, 13 studies were analyzed in the qualitative synthesis (i.e., systematic review) and eight in the quantitative synthesis (i.e., meta-analysis). For the latter, fixed-effect modeling was used to assess the primary outcome (i.e., OCD symptoms). Results: The main findings suggest that GCBT is effective in reducing the symptoms of OCD in adolescents (d = -1.32). However, these results must be interpreted with caution, since all of the included studies showed some bias in their design. Conclusions: GCBT is effective in reducing OCD symptoms in adolescents.

ABSTRACT
BACKGROUND: The available research on the relationship between neuropsychological functioning and the therapeutic outcome of obsessive-compulsive disorder (OCD) has yielded inconsistent results. In this study, our aim was twofold. First, we sought to evaluate the effects of cognitive behavioral group therapy (CBGT) on neurocognitive functions in OCD patients. Second, we assessed the viability of neuropsychological test performance as a predictor of treatment response to CBGT. METHODS: One hundred fifty carefully screened OCD patients were randomized to receive either 12-week CBGT (n = 75) or to remain on a waiting list (WL; n = 75) for the corresponding time. Forty-seven participants dropped out of the study, leaving 103 participants that were included in the analysis (CBGT, n = 61; WL, n = 42). Participants had several neuropsychological domains evaluated both at baseline and at end-point. RESULTS: A significant difference in obsessive-compulsive, anxiety, and depression symptoms was observed between treated patients and controls favoring the CBGT group, but no significant differences were found on neuropsychological measures after 3 months of CBGT. In addition, there were no differences between treatment responders and nonresponders on all neuropsychological outcome measures. Employing a conservative alpha, neuropsychological test performance did not predict CBGT treatment response. CONCLUSIONS: Although the CBGT group demonstrated significant improvement in OCD symptoms, no significant difference was found on all neuropsychological domains, and test performance did not predict treatment response.
