OBJECTIVES: To examine the psychometric properties of the WHOQOL-OLD in Taiwan.  METHODS: Five questionnaires including the WHOQOL-BREF, WHOQOL-OLD, Geriatric Depression Scale (GDS-15), Barthel Index (BI), and Mini-Mental State Examination (MMSE) were used. A total of 524 participants (M = 76.2, SD = 7.5, ages ranged from 60 to 99) from northern and southern Taiwan completed these questionnaires. Cronbach’s alpha, correlation analysis, and factor analysis were conducted to examine internal consistency reliability, content validity, criterion validity, and construct validity. RESULTS: Among the participants, 180 (34.4%) were male, and 344 (65.6%) were female. The results showed that the originally designed 6-factor model of the WHOQOL-OLD was supported. Fit indices (CFI = 0.93, IFI = 0.93, NNFI = 0.92 and RMSEA = 0.06) were acceptable. The internal consistency coefficients (Cronbach’s alpha) ranged from 0.72 to 0.95 for the 6 domains. Content validity coefficients were in the range of 0.41 to 0.80 for item-associated domain correlations. Except for the DAD domain (Death and dying), other domains showed moderate to high inter-domain correlations (Pearson’s correlation ranges from 0.24 to 0.70) and provided good criterion related validity with GDS-15 and WHOQOL-BREF (Pearson’s correlation ranges from 0.23 to 0.55).  CONCLUSIONS: The results showed that the psychometric properties of WHOQOL-OLD were acceptable. The WHOQOL-OLD module is a useful instrument for the old people in Taiwan.
