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

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. R ( 2 ) = 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.
