The Chinese version of the General Health Questionnaire (GHQ-30) was administered to 381 parents of preschool mentally handicapped children, along with other instruments that assessed their stress, mental health, coping styles, and care-giving patterns. The GHQ-30 was found to have high internal consistency as a scale and high item-total correlations for most of the items. Factor analysis with a four-factor solution showed that four factors were abstracted from the scale, namely, anxiety, depression, interpersonal dysfunctioning, and inadequate coping. It also was found that the factors extracted could be reproduced reliably in two random subsamples and that the factor structure derived from the present sample corresponds to the previously reported data on the dimensionality of the Chinese GHQ-30.
