BACKGROUND
Internet and mobile devices can help to improve psychological treatments. Blended group therapy (bGT) has been investigated a several times for anxiety and depression. This mixed methods study is the first to evaluate bGT with a focus on the therapist’s perspective.
OBJECTIVE
To investigate the therapist-related feasibility of bGT.
METHODS
Twenty-seven patients, diagnosed with major depression (48% male, compulsory education= 29.6%), entered treatment at a university outpatient clinic. A computer- and mobile-based system supported the treatment during and between group sessions. Eight novice therapists participated in semi-structured interviews, a subsequent cross-validation survey, and logs on online guidance time and content.
RESULTS
Large to very large pre- to post-treatment effects were found for depression (CES-D; d= 1.51) and general health (d= 1.31). Effects for the secondary outcomes were in the medium range (d= 0.38 – d= 0.71). Tracked completion of online- and mobile tasks (67 – 76%) was comparable to group attendance. The therapists described the support system as helpful in terms of treatment intensification, treatment engagement, and the establishment of the therapeutic relationship. Weekly online guidance took 10.3 minutes per patient, including guidance on exercises (67%) and intimate communication (33%).
CONCLUSIONS
Results suggest a high feasibility of bGT in a gender-balanced, moderately educated sample. bGT provides group therapists with tools for individual care, resulting in an optimization of the therapy process, and high completion rates of the implemented app- and online elements.
