TL;DR: Self-efficacy and planning seemed to be functional as proximal predictors of health behaviors, whereas health risk perception appeared to be a negligible factor when predicting health behaviors.

TL;DR: The delayed effect of coping planning on enactment suggests that coping planning is important for long-term maintenance.

TL;DR: Although health risk perception appeared to be a negligible factor, action planning and recovery self-efficacy were effective predictors of physical exercise adherence.

TL;DR: In this article, the authors examined whether the inclusion of these two planning constructs would improve the overall prediction of physical activity and examined whether intentions moderate the planning-behaviour relationship, and found that intentions moderated the effects of both types of planning on behaviour.

TL;DR: Theories are needed to explain and predict health behavior, as well as for the design and evaluation of interventions as discussed by the authors, and these theories need to be empirically testable in two ways: they need to specify a set of changeable predictors to describe, explain, and predict behavior change and they should enable us to design an effective intervention that produces exactly those changes in behavior that are predicted by the relevant theory.
