【摘要】 目的:探讨减肥人群锻炼行为变化过程的影响因素,在此基础上编制减肥人群锻炼行为变化过程量表。方法:根据心理测量学原理和阶段变化理论,以减肥人群为研究对象,调查减肥人群锻炼行为的影响因素,编制了【减肥人群锻炼行为变化过程量表】。将初测问卷和调整后的问卷分别施测于201名和240名减肥者,采用探索性、验证性因素分析和相关分析对量表的信、效度进行检验。结果:减肥人群锻炼行为阶段变化过程的影响因素为6因素相关模型,量表由6个维度构成,分别为"自我管理"、"环境效果再评价"、"帮助关系"、"意识提高"、"反条件化"和"管理控制"。各分量表同质性信度系数为0.601～0.782,重测信度为0.702～0.801。6因素相关模型的各项拟合指数均在可接受的范围内。结论:【减肥人群锻炼行为变化过程量表】具有可接受的信、效度,可为制定减肥人群锻炼行为干预措施提供有效依据。更多还原

【Abstract】 The factors influencing the changing process of exercise behavior of people on diet were investigated,and the Scale of Changing Process of Exercise Behavior for People on Diet(PCS-DP) was developed based on the principle of psychometrics and the Theory of Stage of Change in exercise psychology.Primary questionnaire and justified questionnaire were applied to 201 and 240 volunteers on diet respectively.Factor analysis and correlation analysis were employed to determine the validity of the inventory.Results suggested that there were 6 influencing factors of the stage change in the exercise behavior,and thus the PCS-DP was constructed with 6 dimensions: self control,environmental reevaluation,helping relationship,consciousness raising,counter conditioning and control management.The ranges of Cronbach’s alpha and the test-retest reliabilities of the subscales were from 0.601 to 0.782 and from 0.702 to 0.801,respectively.Result also revealed that the fitting indices of the 6-factor correlation model were marginally acceptable.It was concluded that the PCS-DP had acceptable reliability and validity and was an effective basis for planning the exercise intervention program for people on diet.更多还原
