Abstract
This article aims to explore the psychometric properties of the 18-item RPWBS amongst youths in Singapore. Participants, who were recruited using convenience sampling, were split into two groups. Both groups (group 1: n = 78; group 2: n = 96) were students recruited from a university in Singapore, aged between 18 and 24 years old. Participants were also recruited from online platforms specific to the school. Internal consistency and construct validity were assessed among both groups of participants, totalling to 174 participants. Test re-test reliability was evaluated among the first group of 74 participants, at three different time-points. Second time-point was at 2 weeks after baseline, and the third time-point was 2 months after the second time-point. Males had significantly greater levels for environmental mastery subscale. Participants from different faculties/courses have significantly different scores for the personal growth subscale. Participants with families/friends with mental health issues scored greater on the autonomy subscale and the personal growth subscale as compared with participants without. There were no differences within the six subscales for (1) residential status, (2) ethnicity, (3) education level (Diploma versus A levels), (4) religion and (5) monthly household income. Exploratory factor analysis revealed a new five-factor structure. Conversely, confirmatory factor analysis found that the original six-factor structure had the best fit, as compared with the new five-factor and single factor structure. The internal consistencies and item total correlations for the subscales of the original six-factor scale were poor. The overall scale internal consistency and test–retest reliability was excellent.
