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’s α for 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 (

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.
