The primary objective of this review is to assess the effects of interactive social media interventions aiming to change health behaviour for adults on health behaviours, physical and psychological health outcomes, and any reported adverse effects.
The secondary objectives are:
- to assess the effects of interactive social media interventions that aim to change health behaviour across population subgroups (defined using PROGRESS-Plus) to assess effects on health equity;
- to use a validated taxonomy of behaviour change techniques to determine whether social media interventions with specific behaviour change techniques (BCTs) (or BCT combinations) are more effective;
- to explore heterogeneity of effects to identify other reasons for differences in effects.
This is a protocol.
