Validity and reliability of the Chinese version of object attachment questionnaire in college students / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To offer a revised Chinese version of the object attachment questionnaire(OAQ), and to examine its reliability and validity in Chinese college students.Methods:Totally 1 350 college students were tested with the Chinese version of OAQ, Chinese version of the saving inventory-revised scale(SI-R), experiences in close relationships inventory(ECR) and emotion attachment questionnaire(EAQ). A total of 100 college students from the sample were followed to complete the Chinese version of OAQ after 4 weeks.Item analysis, correlation analysis, exploratory factor analysis and reliability test were conducted by SPSS 24.0 software, while confirmatory factor nalaysis and convergent validity were conducted by AMOS 21.0.Results:The exploratory factor analysis showed that Chinese version of OAQ included two factors and twelve items.Confirmatory factor analysis showed that the two-factor model fitted well( χ2/ df=3.76, GFI=0.93, CFI=0.90, TLI=0.87, IFI=0.90, RMSEA=0.08). The OAQ positively correlated with SI-R, ECR and EAQ ( r=0.22, 0.34, 0.63, all P<0.01, CR=0.74-0.85, P<0.01.AVE=0.29-0.39, P<0.01). The OAQ had good internal reliability with Cronbach’s α coefficients from 0.78 to 0.83, retest reliability coefficients from 0.87 to 0.97 and split-half reliability coefficients from 0.60 to 0.76(all P<0.01). Conclusion:The Chinese version of OAQ has acceptable reliability and validity.
