The purpose of this study was to examine evidence for the validity of a stages of change measure of the Transtheoretical Model for exercise behavior. Participants were 152 university students (53.3% women, 71.6% Caucasian, M age = 19.18 years) who completed processes of change, self-efficacy, decisional balance, stages of change, and exercise behavior questionnaires as well as a maximal treadmill test. Participants in the action and maintenance stages had the highest strenuous (PC/C/P < A/M) and moderate (PC/C < A/M) self-reported exercise behavior. Those in the maintenance stage had the highest estimated aerobic fitness (PC/P < MA). The differences between the early stages (PC, C, and P) and the later stages (A and M) as described by the first function were primarily due to the behavioral process of change. The differences between the extreme stages (PC and M) and the middle stages (C, P, and A) were due to the experiential processes of change and the pros of decisional balance. The hypothesized patterns of stage differences were partially supported. Failure to obtain full support may have been due to methodological issues or inherent difficulties in detecting evidence for the validity of stages of change measures.
本研究的目的是检验跨理论模型中运动行为改变阶段测量有效性的证据。参与者为152名大学生（53.3%为女性，71.6%为白种人，平均年龄=19.18岁），他们完成了改变过程、自我效能、决策平衡、改变阶段和运动行为问卷以及最大跑步机测试。行动阶段和维持阶段的参与者有最高的高强度（PC/C/P < A/M）和中等强度（PC/C < A/M）自我报告运动行为。维持阶段的参与者有最高的估计有氧适能（PC/P < MA）。第一个函数所描述的早期阶段（PC、C和P）与后期阶段（A和M）之间的差异主要归因于行为改变过程。极端阶段（PC和M）与中间阶段（C、P和A）之间的差异归因于经验改变过程和决策平衡中的益处。阶段差异的假设模式得到了部分支持。未能获得充分支持可能是由于方法学问题或在检测改变阶段测量有效性证据方面存在固有困难。
