Susan Michie et al. ·

Health Psychology

Meta-regression on behaviour-change techniques (BCTs) in diet and physical-activity interventions—self-monitoring as a central effective component.

Key points

  1. Self-monitoring of behaviour explains the largest share of heterogeneity between studies

  2. Self-monitoring combined with other control-theory techniques more effective than other interventions (0.42 vs 0.26)

  3. 122 effect sizes (N = 44,747); overall effect 0.31
