Self-efficacy Moderates the Mediation of Intentions Into Behavior via Plans

Lippke, Sonia·2009·American Journal of Health Behavior

Abstract

OBJECTIVE: To examine the putative moderating role of self-efficacy in the intention-planning-behavior relationship. METHODS: In N=812 individuals, intentions (independent variable) were assessed at baseline, whereas action plans (mediator), self-efficacy (moderator), and physical activity (dependent variable) were measured again 4 weeks later. We examined a moderated-mediation model. RESULTS: Self-efficacy moderates the mediation process: the strength of the mediated effect increased along with levels of self-efficacy. The results remain valid after accounting for baseline physical activity. CONCLUSIONS: For plans to mediate the intention-behavior relation, people must hold sufficiently high levels of self-efficacy. If they lack self-efficacy, planning may be in vain.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
