Treatment experiences during a cognitive behaviour therapy group intervention targeting repetitive negative thinking : a qualitative study

Objectives Treatment of repetitive negative thinking (RNT) focuses rather on individual than group cognitive behaviour therapy (CBT) treatment. Additionally, little is known on how clients experienced these interventions. This study investigates clients' experiences on participating in a CBT group intervention targeting RNT (RNT-G). Design Of the 80 participants, 11 were randomly selected for an in-depth, semi-structured interview after treatment. Interviews focused on what participants experienced as important on group aspects, offered interventions, homework tasks, and possible changes. Methods All participants were adults, diagnosed with major depressive disorder and/or generalized anxiety disorder and being currently in mental health care treatment. After transcribing the interviews, analyses were performed according to the guidelines of thematic analysis. Results Four major themes were identified. First, the group format itself was experienced as an important factor of change. The experiences about the different offered interventions during the group formed a second theme. A third theme related to changes in family or professional life and dealing with RNT as a result of the intervention. Finally, group participation, social interactions, and mental health care treatment were experienced as mutually influencing during the intervention. Conclusions The results of this study shed some light on which treatment interventions were perceived as beneficial during the RNT-G and should therefore be emphasized in treatment. Further, they indicate that the treatment in a group format was experienced as helpful by the participants. Finally, a positive mutual influence between the group intervention and the ongoing individual treatment was experienced
