title: Professional and paraprofessional group treatments for depression: a comparison of cognitive-behavioral and mutual support interventions.
abstract: The relative efficacy of professional and paraprofessional therapists in providing group cognitive-behavioral therapy (CBT) and mutual support group therapy (MSG) was examined. Depressed outpatients (N = 98) were randomly assigned to CBT or MSG led by either 2 professional or 2 paraprofessional therapists. Results suggest that nonprofessionals were as effective as professionals in reducing depressive symptoms and that clients in the CBT and MSG conditions improved equally. Clinically significant improvement was demonstrated for both conditions. However, following treatment, more patients in the professionally led CBT groups were classified as nondepressed and alleviated than in the paraprofessionally led CBT groups. Additionally, therapist adherence to manual-based treatments was associated with greater improvement in clinician-rated depressive symptoms in both conditions and skills in cognitive restructuring were associated with greater improvement among clients in CBT.
