The moderating impact of temporal separation on the association between intention and physical activity: a meta-analysis.

Previous meta-analyses have estimated that the intention-behaviour association in physical activity (PA) is large in magnitude. However, these prior meta-analyses have also revealed a large degree of heterogeneity, suggesting the presence of moderating variables. This study examines the impact of one such moderator, testing the hypothesis that the magnitude of the association between intention and behaviour decreases as the temporal separation between the two increases.
