青少年体育锻炼行为-心理测定量表中文版及其信度效度研究

The adolescent physical exercise behavior-psychological measurement scale on the Chinese version and its reliability and validity study

目的编制适合中国青少年体育锻炼行为-心理特点的中文版测定量表，并评价其信度和效度。方法采用多阶段抽样方法对杭州、武汉、西安3个城市3600名中学生进行问卷调查。用Cronbach’s α系数和分半信度检验其信度；用探索性因子分析和验证性因子分析检验其结构效度，用条目-维度相关系数（IIC）、维度间相关系数、总分与维度间的相关系数检验内容效度。结果中文版青少年体育锻炼行为-心理测定量表的Cronbach’s α系数为0．888，改变策略、决策平衡正向效应、决策平衡负向效应、自我效能4个维度的Cronbach’s α系数分别为0．880、0．706、0．552和0．839；总量表的分半信度为0．851，各分半信度在0．559～0．876之间；探索性因子分析结果显示：3个维度的条目全部被纳入，且累计贡献率均大于40％；结构方程模型分析显示：绝对拟合优度指标GFI=0．972、AGFI=0．958、RMSEA=0．032（90％CI：0．030～0．034）均满足条件，且模型拟合较好；IIC结果显示，4个维度与所含条目之间的Spearman相关系数的范围分别为0．396～0．700、0．470—0．709、0．696～0．771和0．665-0．813，各维度之间有较弱到中度的相关关系，r值范围为0．386～0．935；不同变化阶段的改变策略、决策平衡、自我效能得分不同提示健康干预要有阶段性、针对性。结论中文版青少年体育锻炼行为-心理测定量表在中学生中具有较好的信度和效度，在整体上适用于国内青少年体育锻炼行为-心理的测量。

Objective To develop a suitable physical exercise behavior-psychological scale for the Chinese adolescents and to evaluate its validity and reliability. Methods A total of 3500 junior students were recruited and tested through multistage sampling method. Reliability was assessed, using Cronbach＇s a and split-half reliability; while exploratory factor analysis and confirmatory factor analysis were used to test its validity, with entries-dimension correlation coefficient （IIC） , correlation coefficient between the scores and the dimension, the dimension of correlation coefficient test content validity. Results The internal consistency reliabilities for total scale score （Cronbach＇ s α =0.888）, Cronbach＇ s a of four domains were 0.880, 0.705, 0.552 and 0.839, respectively. The four-domain split-efficacy reliabilities were ranged between 0.559 and 0.876. Data from the exploratory factor analysis revealed the following dimensions： the entries were all inclusive; the cumulative contribution rate was more than 40%. Results from the confirmatory factor analysis showed that the absolute fit measures of GFI=-0.972, AGFI=0.958, RMSEA=0.032 （90%CI： 0.030-0.034） could satisfy the condition while the model fit was better. The results of IIC showed： in the four dimensions, and the contained entries between Spearman correlation coefficient range were 0.396-0.700, 0.470-0.709, 0.696-0.771 and 0.665-0.813, while other dimensions from weak to moderate relationships, the r value range was from 0.386 to 0.935. With the change of the phase changing process, decision balance, self-efficacy scores were differently prompting the health-related intervention periodically and pertinently. Conclusion The reliability and validity of the ＇Adolescent physical exercise behavior-psychological scales （Chinese version） ＇ were good, and could be used to measure the adolescent＇ s physical training behavior-psychological conditions.
