Abstract:
Objective:To adapt the Interdependent Happiness Scale(IHS)into Chinese(IHS-C)version and evaluate its validity and reliability.Methods:Item analysis and exploratory factor analysis(EFA)were conducted on data from 500 adults collected via Credamo.Confirmatory factor analysis(CFA)and multi-group measurement invariance tests were performed on an additional 600 adults.The Simplified Chinese versions of the Depression-Anxiety-Stress Scale(DASS-21),Satisfaction with Life Scale(SWLS),and Flourishing Scale(FS)were used to assess criterion validity and incremental validity.Furthermore,test-retest reliability over a four-week interval was examined in a sample of 245 adults,collected through three university-wide elective courses and two WeChat groups.Internal consistency was assessed with the total sample(n=1 345).Results:EFA revealed a single common factor,explaining 53.80％of the variance,with factor loadings of the items ranging from 0.63 to 0.84.CFA indi-cated a good fit for the one-factor model(x2/df=1.97,CFI=0.99,TLI=0.98,SRMR=0.03,RMSEA=0.04).The scale demonstrated measurement invariance across gender and identity groups(ΔCFI ≤ 0.01,ΔRMSEA 0.015).The scores of IHS-C were negatively correlated with DASS-21 subscale scores(r=-0.65,-0.48,-0.58,Ps＜0.001)and positively correlated with SWLS scores(r=0.82,P＜0.001)and FS scores(r=0.84,P＜0.001).The Cronbach α for IHS-C was 0.89,and the test-retest reliability was 0.73.Conclusion:The Chinese version of the Interdependent Happiness Scale(IHS-C)is a valid and reliable tool for assessing happiness in adults.
