The future of treating atypical depression: Exploring the role of Social Identity Theory in group-CBT

Abstract

Atypical depression (AD) is an overlooked and under-researched form of depression, with little to no research exploring the wide range of non-medication treatment options available. The lack of research in this area is concerning as evidence indicates that symptoms associated with AD include a longer and more severe depressive episode and a greater risk of suicidal behaviour than compared with the more traditional, melancholic depression (Weinstock et al., 2011). To ensure that providers are delivering the best form of intervention, it is essential to explore every treatment option. The present study sought to explore the efficacy of group cognitive behaviour therapy (CBT) on treating AD, with a focus on whether features of social identity theory have an influence during the group-intervention process. In this mixed-method study, participants (N=18) underwent a 10-week group intervention aimed to address issues associated with AD, with data collected pre-intervention, two-week post intervention, and 3-months post intervention to assess the effectiveness of the program. Feedback forms and interviews were undertaken and evaluated to explore whether there was a presence of social identity theory. Results revealed that the intervention significantly reduced depression levels and increased self-esteem levels in participants, indicating that group-CBT is an effective form of intervention for those with AD. Qualitative responses were subjected to thematic analysis, where themes aligning with social identity theory emerged, indicating that features of this theory may have influenced participants’ experiences and signified the importance that a positive group dynamic had in the outcome. This study offers a critical insight into the effectiveness of group-CBT, and provides an alternative and successful treatment option for those who experience AD.
