This study aims to evaluate the internal consistency and factor structure of a psychosocial wellbeing questionnaire designed for older adults in Sibu, Malaysia.
Conducted a community-based cross-sectional study among 1,077 older adults aged 60 and above.
Used multistage stratified sampling to select participants from Sibu, Sarawak.
Administered a 69-item psychosocial wellbeing questionnaire and assessed sociodemographic characteristics.
Evaluated internal consistency using Cronbach’s α and McDonald’s ω, and factorability with KMO and Bartlett’s test.
Performed common factor analysis to explore dimensionality and Tucker’s congruence for cross-group stability.
Total scale reliability was excellent with Cronbach’s α = 0.97 and ω ≈ 0.97.
Most subscales demonstrated good internal consistency, while Block A had lower reliability (α ≈ 0.39).
Strong factorability indices were found (KMO ≈ 0.949, p < 0.001).
Parallel analysis supported retention of nine factors with some conceptual overlap.
Tucker’s congruence analysis indicated strong cross-gender similarity for most factors (φ ≈ 0.89–0.99).
