Validity and reliability of the Chinese version of the Feetham Family Functioning Survey (FFFS).

A Chinese version of the Feetham Family Functioning Survey (Chinese FFFS) was developed and psychometrically tested using a sample of 317 child-rearing mothers in Hong Kong. The Chinese FFFS is a self-administered questionnaire consisting of 25 items from which an instrument discrepant score (d score) can be extracted. The results from the confirmatory factor analysis and exploratory factor analysis confirm that the Chinese FFFS has a five-factor structure based on the family ecological model, thereby affirming its construct validity. Cronbach's alpha for d scores was .91, indicating a high internal consistency. In the test-retest study of 39 mothers, the correlation coefficient for "total d score" over a 2-week period was .82, which showed high test-retest reliability. The highest discrepant scores in family functioning were at the level of the marital relationship, which requires family nurses to be skilled at assessing and intervening at this family subsystem.
