Zoom up your mood - a pilot study examining the efficacy of video-conferencing versus face-to-face delivery of group CBT for depression for out-patients attending a secondary mental health service in Ireland.

Background: Cluain Mhuire is a secondary adult mental health service based in Ireland. The COVID-19 pandemic resulted in many services moving online, including our coping with depression group. A shortened, online version of the face-to-face group was piloted; however, analysis showed that it was not as effective as the longer face-to-face group. Thus, a 12-session, 2.5-hour online group CBT (gCBT) was subsequently run to directly compare the online therapy with the original face-to-face group.

Aims: The primary objective of the study is to evaluate the effectiveness of a 12-week gCBT programme adapted to videoconferencing in reducing self-reported symptoms of depression and anxiety and enhancing quality of life (QoL). Results will be compared with the same group programme delivered face-to-face.

Method: This is a between-groups, naturalistic treatment outcome study. Pre and post measures include the Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and the World Health Organisation Quality of Life Scale (WHOQoL-Bref). A mixed between-within subjects analysis of variance was performed to assess the impact of the three interventions (face-to-face, 8-session online and 12-session online) on participant scores; 112 participants (65 women, 47 men) were recruited (mean age=41.85, SD=13.08).

Results: All three interventions significantly improved depression, anxiety and QoL scores. There was no significant difference between the treatment groups. Attendance was highest in the 12-session online group, followed by the 8-session online group and 12-session in-person group.

Conclusions: These results add to the growing evidence supporting the effectiveness of internet-delivered gCBT in reducing depressive symptoms.
