目的：探讨跨理论变化模型在预测青少年运动中的效用。设计：前瞻性研究：在基线和随访6个月后进行评估。方法：采用分层随机抽样方法对1055名在港中国高中生进行调查，其中533人在6个月后进行随访，完成改变阶段（SCQ）、自我效能感（SEQ）、运动利弊认知（DBQ）和改变过程（PCQ）测试。数据分析采用单因素方差分析、重复测量方差分析和独立样本t检验。结果：TTM预测该人群运动的效用不强；自我效能感和决策平衡的增加在基线和随访时保持活跃的人之间有所区别，但在从不活跃状态（例如，预思考或沉思）到活跃状态（例如，维护）的变化中没有区别，因为人们可以预期TTM的分期算法。结论：TTM是中国年轻人未来运动改变阶段的适度预测因子。有证据表明，随着时间的推移，TTM变量可能会影响运动，自我效能感、优点和行为变化过程似乎是最强的预测因素。2009爱思唯尔有限公司版权所有。
Objectives: To investigate the utility of the Transtheoretical Model of Change in predicting exercise in young people.Design: A prospective study: assessments were done at baseline and follow-up 6 months later.Method: Using stratified random sampling 1055 Chinese high school pupils living in Hong Kong, 533 of who were followed up at 6 months, completed measures of stage of change (SCQ), self-efficacy (SEQ), perceptions of the pros and cons of exercising (DBQ) and processes of change (PCQ). Data were analysed using one-way ANOVA, repeated measures ANOVA and independent sample t tests.Results: The utility of the TTM to predict exercise in this population is not strong; increases in self-efficacy and decisional balance discriminated between those remaining active at baseline and follow-up, but not in changing from an inactive (e.g., Precontemplation or Contemplation) to an active state (e.g., Maintenance) as one would anticipate given the staging algorithm of the TTM.Conclusion: The TTM is a modest predictor of future stage of change for exercise in young Chinese people. Where there is evidence that TTM variables may shape movement over time, self-efficacy, pros and behavioural processes of change appear to be the strongest predictors. (C) 2009 Elsevier Ltd.
