The entire Transtheoretical Model, consisting of stages of change, processes of change, self-efficacy, and decisional balance, was tested for its applicability to understanding exercise behavior in an adolescent population.
Students (n = 819) from five community high schools (Grades 9-12) completed self-administered questionnaires, all of which were adapted from previous literature. Stage of exercise behavior change served as the dependent variable.
Distribution of the sample across the stages was: precontemplation, n = 17 (2.1%); contemplation, n = 34 (4.2%); preparation, n = 235 (28.7%); action, n = 129 (15.7%); and maintenance, n = 404 (49.3%). Univariate analyses of variance (p < 0.0038) followed up with Tukey's post-hoc analyses revealed that all of the constructs differed significantly across stages. Profile analysis indicated that pros and cons intersected in the action stage using t scores; however, when analyzing raw scores, this intersection was found to be in the precontemplation stage.
Preliminary evidence was found for the applicability of the Transtheoretical Model to adolescents. The low rate of adolescents in the precontemplation and contemplation stages was not deemed a major limitation, owing to the purpose of the investigation.
对由变化阶段、变化过程、自我效能感和决策平衡组成的整个跨理论模型进行测试，以检验其在理解青少年群体运动行为方面的适用性。
来自五所社区高中（9 - 12年级）的819名学生完成了自填式问卷，所有问卷均改编自先前的文献。运动行为变化阶段作为因变量。
样本在各阶段的分布情况为：未考虑阶段，n = 17（2.1%）；考虑阶段，n = 34（4.2%）；准备阶段，n = 235（28.7%）；行动阶段，n = 129（15.7%）；维持阶段，n = 404（49.3%）。单因素方差分析（p < 0.0038）及后续的Tukey事后分析表明，所有结构在各阶段均存在显著差异。轮廓分析表明，使用t分数时利弊在行动阶段相交；然而，在分析原始分数时，发现这种相交出现在未考虑阶段。
发现了跨理论模型适用于青少年的初步证据。由于调查目的，未考虑阶段和考虑阶段青少年比例较低并不被视为主要限制因素。
