Further validation of the Maudsley Marital Questionnaire (MMQ)

Abstract

This study examined the Factor structure and internal consistency of the Dutch version of the Maudsley Marital Questionnaire (MMQ) for a sample of 787 respondents in Belgium. Principal components analysis, followed by varimax orthogonal rotation, identified the expected three factors (M – Marital, S – Sexual, GL – General Life), which jointly explained 53% of the variance. The Cronbach α for MMQ – M (.90) and MMQ – S (.80) were of high value while for MMQ – GL (.66) was lower. The MMQ scales were found significantly correlated with each other: M – S, .60; M – GL, .46 and S – GL, .33.
