title: Validity and reliability of the Chinese version of the care transition measure.
abstract: BACKGROUND
  The 15-item care transition measure (CTM-15) is a reliable and valid instrument assessing the quality of care transition from patients' perspectives. The aim of this study was to evaluate the psychometric properties of the CTM-15 and the CTM-3 (a 3-item short version of the CTM-15) in Mainland China.
  
  
  RESULTS
  This was a cross-sectional study with a convenience sample of 646 patients in a general tertiary-level hospital in Chengdu, China. The results indicated that the Cronbach's α values of the Chinese version of the two measures were 0.90 and 0.56, and the test-retest reliability values were 0.91 and 0.87, respectively. Three factors were extracted for the CTM-15 in Chinese populations. The CTM-15 and the CTM-3 scores discriminated well between patients with and without re-hospitalization for their index condition. The CTM-15 and the CTM-3 had significant positive relationships with self-rated health status. The CTM-3 score was significantly related to the CTM-15 score, and the CTM-3 score accounted for 64.23% of the variance of the CTM-15 score.
  
  
  CONCLUSIONS
  This study has demonstrated the psychometric properties of the CTM-15 and the CTM-3 in Mainland China. Although the Cronbach's α value of the CTM-3 is suboptimal, it has exhibited high test-retest reliability, convergent validity and criterion validity. Therefore, the CTM-3 can substitute the CTM-15 as a performance measurement tool when the sample size is large enough to compensate its suboptimal reliability or the reduced response burden is a concern.
