Psychometric Characteristics and Factor Analysis of the Persian Version of Couples Satisfaction Index

Bachground: The concept of couples’ satisfaction is one’s subjective evaluation of marital relationship and the level of perceived happiness from this relationship. Couples Satisfaction Index (CSI) is a self-report measure to assess marital satisfaction. This study aims to evaluate the psychometric characteristics of the Persian version of CSI in a non-clinical sample. Materials and Methods: Factor analysis, translation, structural, convergent validity, and reliability of this index were investigated in 150 married students of Tehran and Shahed Universities recruited by convenience sample method. Results: According to the results of the exploratory factor analysis, four factors of “marital happiness”, “warmth of the relationship”, “being together”, and “right choice” were identified in the Persian version of CSI. The specifications of exploratory factor analysis were good. The results of the confirmatory factor analysis showed that four factors of the CSI are more valid and reliable. The reliability of the index was 0.96 determined by Cronbach α. The convergence between this index and Locke–Wallace Marital Adjustment Test (MAT) was calculated to be 0.9. Conclusion: results indicate that Persian version of CSI has appropriate psychometric characteristics. Therefore, this measure can be confidently used in this field of research.
