Psychometric properties of the Chinese Version of the Readiness for Hospital Discharge Scale for people living with HIV

Objective:The study was conducted to validate the reliability and factor structure of the Chinese version of the Readiness for Hospital Discharge Scale(RHDS-CH)for people living with HIV(PLWH).Methods:From May 2017 to November 2017,a cross-sectional survey was performed in two AIDS inpatient departments located in two cities in Hunan,China.Reliability was evaluated by examining the internal consistency and split-half reliability of the items.A confirmatory factor analysis was performed to assess the factor structure of the RHDS-CH,and the model was revised according to the modification index.Results:Cronbach'sαfor the RHDS-CH was 0.912,and the split-half reliability of the total scale was 0.831.Initially,the results of the confirmatory factor analysis indicated that the sample did not fit this four-factor model and its 23 items well(x2/df=3,GFI=0.772,TLI=0.823,CFI=0.844,RMSEA=0.100).To improve the model fit indices,we performed model modification with the guidance of modification indices.Finally,the model fit indices showed an acceptable fit to the data(x2/df=2.141,GFI=0.844,TLI=0.899,CFI=0.915,RMSEA=0.075).Coefficients of corrected item-total correlation of the RHDS-CH ranged from 0.435 to 0.726.Conclusion:This study is the first to examine the psychometric properties of the RHDS-CH for PLWH.Our findings showed good reliability and confirmed the four-factor structure model for PLWH.
