This meta-analysis examined the effect of transdiagnostic cognitive-behavioral therapy (T-CBT) in adults, children, and adolescents with emotional disorders, exploring the effects of possible moderator variables on efficacy.
In contrast with previous reviews, only studies employing transdiagnostic theory-based protocols were included.
A total of 48 studies reporting on 6291 participants were identified. Treatment efficacy was examined using a random effects model and taking into account pre- and post-treatment data.
Results within the adult population showed large overall effect sizes on anxiety (randomized controlled trials [RCTs]: g = 0.80; Uncontrolled studies: g = 1.02) and depression (RCTs: g = 0.72; Uncontrolled studies: g = 1.08) that were stable at follow up.
Preliminary analysis with children and adolescents showed medium effect sizes on anxiety (g = 0.45) and depression (g = 0.50).
No significant differences between T-CBT and disorder-specific CBT were found. Overall, results support the efficacy of T-CBT for emotional disorders.
