摘　　要：目的 评价中文版青少年久坐行为量表在初中生应用的信度和效度.方法 采用多阶段抽样的方法 ,对782名初中生进行问卷调查.用Cronbach＇s α系数和分半信度考核其信度,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考核其内容效度,用证实性因子分析考核其结构效度.结果 中文版青少年久坐行为量表的Cronbach＇s α系数为0.822,改变策略、决策平衡正面效应维度、决策平衡负面效应、自我效能四个维度的Cronbach＇s α系数分别为0.882,0.478,0.631,0.645;总量表分半信度为0.857,各维度分半信度在0.488～0.896;条目与维度间平均相关系数0.226～0.768,除决策平衡负面效应得分与改变策略、决策平衡正面效应得分间的相关系数分别为-0.052,0.090（P＜0.05）外,其他各维度得分间有较弱到中度的相关关系（r=-0.210～0.394,P＜0.01）,4个维度得分与总分间均有中度到较强的相关关系（r=0.365～0.554,P＜0.01）.结论 中文版青少年久坐行为量表在初中生中具有较好的信度和效度,在整体上适用于国内初中生久坐行为的测量.Objective To evaluate the reliability and validity of adolescent sedentary behavior scales （ Chinese version） in junior middle school students. Methods A total of 782 junior students were tested through multistage sampling method. The reliability was assessed, using Cronbach＇s αcoefficient and split-half reliability,while its validity was tested through ICC, correlation analysis and confirmatory factor analysis. Results The internal consistency reliability for total scale score （ Cronbach＇s α = 0.822 ） ,change strategies score （ Cronbach＇s α =0.882 ）, decisional balance/pros score（ Cronbach＇s α = 0.478 ）, decisional balance/cons score （ Cronbach＇s α =0.631 ） ,and self-efficacy score （Cronbach＇s α = 0.645 ） ;the split-half reliability for total scale score was 0.857,four domains split-half reliability ranged between 0.488 ～ 0.896; the correlations between items and the domains ranged 0.226 ～ 0.768, except the correlations coefficients between decisional balance （cons score） and change strategies score, decisional balance （ cons score） and decisional （ pros score） were - 0.052,0.090 （ P 〈 0.05 ）,respectively. Low to moderate correlations between domains ranged from -0.210 to 0.394 （ P 〈 0.01 ）, while moderate to high correlations between domain and total scale. Correlation coefficients ranged between 0.365 to 0.554（ P 〈 0.01 ）. Conclusion The reliability and validity of adolescent sedentary behavior scales （ Chinese version） were good, and adapt to measure junior middle school students＇ sedentary behavior.
