Reliability and equivalence of the Spanish translation of the Marital Satisfaction Inventory--Revised (MSI-R)

This study examined the reliability and linguistic equivalence of the Spanish translation of the Marital Satisfaction Inventory--Revised (MSI-R) in a sample of 86 bilingual Mexican American couples. Overall, findings provided preliminary support for using this translation of the MSI-R with respondents whose preferred language is Spanish. Coefficients of internal consistency and temporal stability for scales constituting the Spanish MSI-R averaged .72 and .75, respectively. Linguistic equivalence coefficients for respondents completing the MSI-R in both languages averaged .69. Multivariate analyses of variance indicated no significant effect for language of administration on MSI-R scale scores. Discussion emphasizes caveats in using the Spanish MSI-R and directions for further research.
