Abstract
The aim of the study was to evaluate the psychometric properties of the Chinese version of Medical Outcomes Study Family and Marital Functioning Measures (C-MOS-FMFM) in Hong Kong Chinese childbearing families. A cross-sectional survey was conducted using a convenience sample of 128 childbearing couples recruited from antenatal clinics. The C-MOS-FMFM demonstrated good internal consistency (Cronbach's alpha = 0.79) and test-retest reliability (intraclass correlation coefficient = 0.74). Significant correlations with Medical Outcomes Study-Social Support Survey (r = 0.38, P < 0.01) and Trait Anxiety Inventory (r = -0.48, P < 0.01) supported construct validity. Factor analysis identified one factor corresponding to family functioning and two factors corresponding to marital functioning. The C-MOS-FMFM has satisfactory psychometric properties. It has the potential to be used as a clinical and research instrument for measuring family and marital functioning in the Chinese population.
