Evaluation and exploration of a social prescribing initiative: Study protocol.

Attention is being given to healthcare initiatives with the potential to save money and improve lives. One example is social prescribing, which supports patients whose ill-health is exacerbated by loneliness. While evidence has accumulated attesting to social prescribing's efficacy, one limitation has been the lack of a theoretical framework, which limits understanding of how tackling loneliness improves health. In our evaluation of a social prescribing pathway, we adopt a 'Social Cure' approach, which posits that social relations affect health. Our study will evaluate the efficacy of the pathway and determine the extent to which group processes are responsible for health improvements.
