The stages of change construct of the Transtheoretical Model (TTM) has been proposed for examining exercise adoption. Studies investigating the construct validity of the stages of change for exercise have used physical activity of moderate or higher intensity as operationalization criterion. Since it has been shown that physical activity of lower intensity also provides health benefits, we investigated whether the stages of change appropriately address lower intensity physical activity. Data with respect to the stages of change as well as behavior, intention and self-efficacy associated with mild, moderate, and strenuous exercise were collected in a sample of 467 males and females aged 20 - 85. Results show that the stages of change can be distinguished by moderate and strenuous but are not consistent with mild exercise. Implications for future research utilizing the stage of change conceptualization are discussed and development of new stage assessment instruments for mild exercise is recommended.
跨理论模型（TTM）的行为改变阶段结构已被提出用于研究运动习惯的养成。调查运动行为改变阶段结构效度的研究将中等强度或更高强度的身体活动作为操作标准。鉴于已有研究表明低强度身体活动也有益健康，我们调查了行为改变阶段是否适用于低强度身体活动。我们收集了467名年龄在20至85岁之间的男性和女性的数据，这些数据涉及行为改变阶段以及与轻度、中度和剧烈运动相关的行为、意图和自我效能。结果表明，行为改变阶段可以通过中度和剧烈运动来区分，但与轻度运动不一致。本文讨论了未来利用行为改变阶段概念化进行研究的意义，并建议开发针对轻度运动的新阶段评估工具。
