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.
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.
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.
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.
The results provide useful information for intervention campaigns and demonstrate a need to consider adoption and maintenance profiles.
大多数人虽有参与体育活动（PA）的积极意愿，但却未能付诸行动；因此，为了集中干预力量，有必要了解如何成功地将意愿转化为行为。
本研究的目的是检验跨理论模型、计划行为理论和保护动机理论的构成要素，作为加拿大职场样本中6个月内体育活动意愿-行为概况的预测因素。
来自艾伯塔省三个大型组织的员工（n = 887）完成了一项基线调查，内容涉及他们的人口统计学和医学背景、体育活动以及社会认知构成要素。6个月后，共有611名参与者完成了第二次评估。
参与者被分为五种概况：无意愿者、未成功采纳者、成功采纳者、未成功维持者和成功维持者。对体育活动的感知重要性和关注度（认知过程、工具性态度、感知严重性）将无意愿者与其他四种概况区分开来，行为的自我管理和自我调节（行为过程、自我效能）将成功采纳者与未成功采纳者区分开来，而对限制因素的控制（缺点、感知控制、自我效能）是成功维持者与未成功维持者的关键区分因素。
研究结果为干预活动提供了有用信息，并表明有必要考虑采纳和维持概况。
