Abstract

This study was to develop an 18-item Brief Wisdom Development Scale, based on the original 66-item Wisdom Development Scale, and evaluate the psychometric properties of the proposed scale using a sample of older adults. This longitudinal study recruited 153 community-dwelling adults (mean = 72.55 years old; SD = 8.47) from older adult service centres. Using a repeated measures design, the study obtained four waves of data from the participants over 12 months. The Brief Wisdom Development Scale (BWDS) was developed based on the Stepwise Confirmatory Factor Analytical approach (SCOFA), with further verification of its factorial validity using confirmatory factor analysis (CFA). The results suggest that the BWDS comprising 18 items with a six-factor structure is comparable with its full version and possesses good psychometric properties in internal consistency, concurrent validity, and factorial validity. The BWDS provides an efficient, reliable, and valid construct to measure wisdom. The implications for research development are discussed here.
