Abstract: This study explored whether the psychological composition of a group, with respect to mood, catastrophising, fear of movement and pain self-efficacy characteristics at baseline, is associated with in iduals’ treatment outcomes following group cognitive behavioural therapy (CBT)-based programmes for chronic pain. Retrospective analyses of outcomes from two independently run CBT-based pain management programmes (Programme A: N = 317 and Programme B: N = 693) were conducted. Mixed modelling analyses did not consistently support the presence of associations between group median scores of depression, catastrophising or fear avoidance with outcomes for in iduals in either programme. These results suggest that the psychological profiles of groups are not robust predictors of in idual outcomes in CBT groups for chronic pain. By implication, efforts made to consider group composition with respect to psychological attributes may be unnecessary.

Abstract: 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 in idual 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. 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. 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. 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.

Abstract: The complement receptor Ig (CRIg) is selectively expressed by macrophages. This receptor not only promotes the rapid phagocytosis of bacteria by macrophages but also has anti-inflammatory and immunosuppressive functions. Previous findings have suggested that protein kinase C (PKC) may be involved in the regulation of CRIg expression in human macrophages. We have now examined the role of PKCα in CRIg expression in human monocyte-derived macrophages (MDM). Macrophages nucleofected with plasmid containing short hairpin RNA against PKCα showed markedly reduced expression of PKCα, but normal PKCζ expression, by Western blotting analysis, and vice versa. PKCα-deficient MDM showed increased expression of CRIg mRNA and protein (both the long and short form), an increase in phagocytosis of complement-opsonized Candida albicans, and decreased production of TNF-α and IL-6. TNF-α caused a marked decrease in CRIg expression, and addition of anti-TNF mAb to the TNF-α–producing MDMs increased CRIg expression. PKCα-deficient macrophages also showed significantly less bacterial LPS-induced downregulation of CRIg. In contrast, cells deficient in PKCα showed decreased expression of CR type 3 (CR3) and decreased production of TNF-α and IL-6 in response to LPS. MDM developed under conditions that increased expression of CRIg over CR3 showed significantly reduced production of TNF-α in response to opsonized C. albicans. The findings indicate that PKCα promotes the downregulation of CRIg and upregulation of CR3 expression and TNF-α and IL-6 production, a mechanism that may promote inflammation.
