RESUMO
Disorder-specific cognitive behavior therapy (DS-CBT) is effective at treating major depressive disorder (MDD) while transdiagnostic CBT (TD-CBT) addresses both principal and comorbid disorders by targeting underlying and common symptoms. The relative benefits of these two models of therapy have not been determined. Participants with MDD (n=290) were randomly allocated to receive an internet delivered TD-CBT or DS-CBT intervention delivered in either clinician-guided (CG-CBT) or self-guided (SG-CBT) formats. Large reductions in symptoms of MDD (Cohen's d≥1.44; avg. reduction≥45%) and moderate-to-large reductions in symptoms of comorbid generalised anxiety disorder (Cohen's d≥1.08; avg. reduction≥43%), social anxiety disorder (Cohen's d≥0.65; avg. reduction≥29%) and panic disorder (Cohen's d≥0.45; avg. reduction≥31%) were found. No marked or consistent differences were observed across the four conditions, highlighting the efficacy of different forms of CBT at treating MDD and comorbid disorders.

Generalized anxiety disorder (GAD) can be treated effectively with either disorder-specific cognitive behavior therapy (DS-CBT) or transdiagnostic CBT (TD-CBT). The relative benefits of DS-CBT and TD-CBT for GAD and the relative benefits of delivering treatment in clinician guided (CG-CBT) and self-guided (SG-CBT) formats have not been examined. Participants with GAD (n=338) were randomly allocated to receive an internet-delivered TD-CBT or DS-CBT intervention delivered in either CG-CBT or SG-CBT formats. Large reductions in symptoms of GAD (Cohen's d ≥ 1.48; avg. reduction ≥ 50%) and comorbid major depressive disorder (Cohen's d ≥ 1.64; avg. reduction ≥ 45%), social anxiety disorder (Cohen's d ≥ 0.80; avg. reduction ≥ 29%) and panic disorder (Cohen's d ≥ 0.55; avg. reduction ≥ 33%) were found across the conditions. No substantive differences were observed between DS-CBT and TD-CBT or CG-CBT and SG-CBT, highlighting the public health potential of carefully developed TD-CBT and SG-CBT.
