Abstract:
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.
