Influence of social networks on cancer survivors' self-management support: A mixed methods study

Abstract

Objective: The role of social networks, especially weaker ties (e.g. casual acquaintances and hobby groups), in self-management of long-term consequences of cancer is unexplored. This study aimed to explore the structure of cancer survivors' social networks and their contribution to self-management support and health-related quality of life (HRQoL). Methods: The study used a sequential, exploratory mixed methods design. Phase 1 surveyed 349 lymphoma, colorectal, breast and prostate cancer survivors. Phase 2 analysed 20 semi-structured interviews with respondents recruited from Phase 1. Results: Phase 1 results suggested participants' HRQoL increased if they participated in an exercise group, if their self-management skills increased, and social distress and negative illness perception decreased (p < 0.0005 adj. R2 = 0.631). These findings were explored in Phase 2, identifying underlying mechanisms. Four themes were identified: disrupted networks after cancer treatment; navigating formal support and building individual capacity; peer networks and self-management knowledge and linking networks to enable adaptation in recovery. Conclusions: This study suggests engagement with community groups, particularly those not directly related to illness management and social interaction with weak ties, make a valuable contribution to self-management support, increase HRQoL and enhance well-being.
