Psychometric testing of the C hinese M andarin version of the M ental H ealth I nventory among C hinese patients with coronary heart disease in M ainland C hina

This study aimed to develop a C hinese M andarin version of the M ental H ealth I nventory ( CM : MHI ). The E nglish version MHI was translated into C hinese (simple C hinese character) using the forward‐backward translation method while establishing the semantic equivalence and content validity. A convenience sample of 204 coronary heart disease ( CHD ) patients was recruited to evaluate the internal consistency, concurrent validity and construct validity of the CM : MHI . Forty patients completed the CM : MHI to evaluate the test–retest reliability after 2 weeks. The CM : MHI demonstrated good semantic equivalent rate (92%) and satisfactory content validity index (0.91). The internal consistency was acceptable for total and all subscales with C ronbach's alpha greater than 0.70, with the exception of the subscale of E motional T ies (Cronbach's alpha = 0.64). The test–retest reliability was also satisfactory with intraclass correlation coefficients higher than 0.75. The concurrent validity was acceptable with significantly strong correlations between the CM : MHI and the C hinese M andarin versions of S hort F orm 36 H ealth survey and H ospital A nxiety and D epression S cale. Confirmatory factor analysis further supported the five‐factor structure of the CM : MHI . The CM : MHI demonstrated to be a valid and reliable measure for assessing psychological distress and well‐being in C hinese‐speaking CHD patients.
