Abstract

Objectives: To investigate the psychometric properties of the persian version of the Satisfaction With Life Scale (SWLS-P) among older adults in Tabriz.

Design: A cross-sectional study.

Setting(s): Tabriz, the capital of East Azerbaijan province, Iran.

Participants: A representative sample of 1362 (768 females and 594 males) community-dwelling people aged≥60 participated in the current study.

Outcome measures: The psychometric properties of the SWLS-P were evaluated. The standard translate/back-translate procedure was applied. Then, using an expert panel, the face and content validities were assessed. Exploratory and confirmatory factor analysis (EFA and CFA) and structural equation modeling (SEM) were used to investigate the factorial structure, and data were analyzed using SPSS software version 23 and AMOS version 18.

Results: Cronbach’s alpha calculated for the SWLS-P was 0.883, showing desirable internal consistency and reliability for the SWLS. Furthermore, CFA confirmed the single-factor structure of the Persian version of the scale and indicated an appropriate fit, with a root mean square error of approximation (RMSEA) of 0.049, a comparative fit index (CFI) of 0.997, a Tucker-Lewis Index (TLI) of 0.991, and a Chi-square to degrees of freedom (DF) ratio of 4.289.

Conclusions: The results supported the validity and reliability of the SWLS-P for use with Iranian older adults.
