Predicting the Physical Activity Intention–Behavior Profiles of Adopters and Maintainers Using Three Social Cognition Models

Abstract

BACKGROUND: Most of the population have positive intentions to engage in physical activity (PA) but fail to act; thus, the need to understand successful translation of intention into behavior is warranted in order to focus intervention efforts. PURPOSE: The objective of the study is to examine constructs of the transtheoretical model, theory of planned behavior, and protection motivation theory as predictors of physical activity intention-behavior profiles across 6 months in a Canadian workplace sample. METHODS: Employees from three large organizations in the province of Alberta (n = 887) completed a baseline survey relating to their demographic and medical background, PA, and social-cognitive constructs. A total of 611 participants completed a second assessment 6 months later. RESULTS: Participants were grouped by five profiles: nonintenders, unsuccessful adopters, successful adopters, unsuccessful maintainers, and successful maintainers. Perceived importance and concern for PA (cognitive processes, instrumental attitude, perceived severity) distinguished nonintenders from the other four profiles, self-management and self-regulation of the behavior (behavioral processes, self-efficacy) distinguished successful adopters from unsuccessful adopters, while control over constraints (cons, perceived control, self-efficacy) were the key discriminators of successful maintainers from unsuccessful maintainers. CONCLUSION: The results provide useful information for intervention campaigns and demonstrate a need to consider adoption and maintenance profiles.
