Are group identity and sense of belonging relevant for group pain management programmes? An exploratory pilot study.

Introduction: Cognitive Behaviour Therapy (CBT)-based programmes for chronic pain are often conducted in groups, most likely for time and cost efficiencies. However, there has been very little investigation of the role that the group itself, and particularly the processes occurring within the group, may play in individual outcomes. The objective of this study was to explore whether social group processes were relevant to key treatment outcomes of group CBT for chronic pain. Method: Data were collected from 15 groups (N = 118) undertaking a pain management programme in a tertiary setting. Intraclass correlations were computed to determine any clustering of outcomes in groups, and linear mixed modelling analysis explored pre-registered hypotheses of associations between treatment outcomes and the social group processes of Group Identification and Sense of Belonging. Results: A weak association between early identification with the group and changes in pain-related disability was shown. In addition, an enhanced global Sense of Belonging was associated with increased pain self-efficacy. Conclusion: These associations, in a programme that had not been designed to address group processes, suggest that their relevance is worth further investigation, particularly in group programmes that do focus on the social consequences of chronic pain. Future studies should investigate whether manipulation of social group processes within a CBT-based pain programme enhances pain-related outcomes and improves the overall well-being of people with chronic pain.
