Internal consistency and factor structure of the Chinese Health Questionnaire

ABSTRACT The internal consistency and factor structure of the Chinese Health Questionnaire (CHQ) were investigated in 2 samples in Taiwan, one from 3 communities ( n = 1023) and the other from consecutive attenders for health screening in a general hospital ( n = 386). Cronbach's alpha coefficients were calculated to be 0.84 and 0.83 for the 12‐item and 0.90 and 0.92 for the 30‐item CHQ version. Four factors similarly extracted for the CHQ‐30 in both samples include somatic symptoms, anxiety and worrying, social dysfunction, and depression and poor family relationship. The implications of these findings were discussed from a cross‐cultural perspective.
