Abstract: Objective · To introduce and localize the Adolescence Reasons for Quitting Scale (ARFQ) and test its reliability and validity. Methods · Convenient sampling was used. Three hundred and eighty-four high school students were selected as sample 1 for item analysis, exploratory factor analysis, discriminant validity test, internal consistency reliability and split-half reliability. One hundred and ninety-one high school students were selected as sample 2 for confirmatory factor analysis. Four weeks later, 60 students in sample 1 were selected for retest. Results · The Chinese version of ARFQ included 4 dimensions and 16 items. Four common factors extracted by exploratory factor analysis were named "Short-Term Consequences" "Long-Term Concerns" "Social Disapproval" and "Relatives' and Friends' Disapproval", and the cumulative variance contribution rate was 64.04%. Confirmatory factor analysis showed that four-factor model fitted well [χ2/df=2.06, root mean square error of approximation (RMSEA) =0.05, incremental fit index (IFI) =0.95, goodness of fit index (GFI) =0.94, adjusted goodness of fit index (AGFI) =0.91, and Tucker-Lewis index (TLI) =0.94]. The Cronbach's α coefficient of the scale was 0.79, and the coefficient of each dimension was 0.72-0.90. The split-half reliability was 0.76, and the test-retest reliability was 0.84. Conclusion · The Chinese version of ARFQ is a valid and reliable instrument to measure the motivation of adolescents' quitting smoking.
