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.
