Objective: To examine the reliability and validity of the translated Chinese version of Social Capital Questionnaire for Adolescent Students (SCQ-AS), and to verify its application in Chinese adolescent students so as to provide a measurement tool for the study of social education for young students.
Methods: From April to May 2016, we selected 350 students from Zhangwu County, Liaoning Province as the subjects of this study by using convenient sampling method. The finished Chinese version of SCQ-AS under Chinese cultural context used in this study was finally developed after 2 revisions and improvements of the original Chinese version of SCQ-AS translated by 4 teachers and students of nursing, the first revision and improvement was based upon the suggestions of 2 primary and junior high school English teachers with no medical background, and the second was based on the pre-survey results. With the Chinese version of SCQ-AS, we conducted a formal anonymous survey in the subjects, and a second survey in 60 of whom two weeks later.
Results: A total of 334 valid questionnaires were obtained, with a response rate of 95.4%. The results of the surveys showed that the Cronbach′s α, split-half reliability coefficient, and retest reliability coefficient of the questionnaire was 0.829, 0.692 and 0.710, respectively (P＜0.001). The scores of each item in the Chinese version of SCQ-AS were positively correlated with the total score, r values ranged from 0.458 to 0.715 (P＜0.05). The Chinese version of SCQ-AS was assessed by 5 nursing experts, and the content validity index was 0.816. Four common factors with eigenvalues ＞1.000 were extracted by exploratory factor analysis with a cumulative variance contribution rate of 66.369%. Common factor 1 had greater loads on items from 5 to 7, and item 10, while common factor 2 had those on items from 1 to 4, common factor 3 had those on items 8 and 9, and common factor 4 had those on items from 10 to 12. Confirmatory factor analysis showed that χ2/df=1.874, GFI=0.922, CFI=0.937, TLI=0.914, IFI=0.939, RMSEA=0.071, AGFI=0.874, NFI=0.878, which indicated that the fitness of theoretical structure of Chinese version of SCQ-AS was good.
Conclusion: Chinese version of SCQ-AS has good reliability and validity, which can be used as a tool for the investigation of social capital of young students in China.
