Abstract: The purpose of this study is to investigate the validity and reliability of the Chinese short version of the Evaluation Instrument of Chronic Disease Self-management Program (CDSMP). Firstly, the study reviewed the content validity and cultural relevancy of the Chinese short version of the Evaluation Instrument and conducted a pilot reliability study. Secondly, the construct validity of the Evaluation Instrument was evaluated by exploratory factor analysis. Third, we studied the test-retest reliability of the Evaluation Instrument. Last, the relationship among the core domains of CDSMP, i.e., self-management behaviors, self-efficacy and self-management behaviors would also be examined. In the review content validity and cultural relevance, a review panel consisted of three health care professionals and three experienced lay leaders of CDSMP was formed, fifteen subjects with chronic diseases with no experiences in CDSMP were recruited to give comments on the relevance and representatives of items in the Chinese short version of the Evaluation Instrument. In the study of construct validity by exploratory factor analysis, one hundred and thirty seven subjects were recruited. The factor analysis reviewed three multi-item subscales under the self-management behaviors, one subscale under the self-efficacy domain and four subscales under the health status domain. In most of the subscales under the three domains, a single factor structure was identified except one of the subscales of the self-management behaviors. Results also indicated that two of the subscales, the exercise subscale (Q14) of the self-management behavior domain and the Dlness Intrusiveness Rating Scale (Q2S) of the health status domain, did not have a stable factor solution identified and were suspended from further test-retest reliability study. All the subscales included in the test-retest reliability study had good to excellent reliability (ICC ranged from .71 to .98; with a ranged from .73 to.96). In the correlation analysis, it was found that the Self-efficacy scores had significant negative and moderate correlation with Health Status domain (r ranged from -.60 to .28) and had significant and weak correlation only with the Exercise Behaviors subscale of the Self-management Behaviors domain (r = .22), while only the Exercise Behaviors subscale of the Self-management Behavior domain had significant positive and fair correlation with Health Status scores (r ranged from -.22 to .41). Issues on sampling, testing intervals and needs for further studies were discussed. Additional items were suggested to improve validity in measuring outcomes of CDSMP.
