Dimensionality and reliability of a modified version of Norton's 1983 Quality Marriage Index among expectant and new Canadian mothers'.
A slightly modified version of Norton's 1983 Quality Marriage Index was administered to 61 expectant mothers prior to giving birth and within 3 mo. after giving birth. Mothers' ages ranged from 19 to 43 years (M = 30, SD = 5.01) and their partners' ages ranged from 21 to 48 years (M = 32, SD = 6.02). Mothers were presented an opportunity to participate in this study during prenatal classes held at hospital and community health centers. The only requirement for participation was that the mother be residing with her child's father for the duration of the study. The six items of the modified index showed high internal consistency (alpha > .90) and substantial test-retest reliability with a Pearson zero-order correlation of .65 across the two administrations. Maximum likelihood factor analysis indicated moderate support for unidimensional factor structure for the modified index, but removing one item from the pre- and postnatal administration improved the factor structure. In the first administration, the last item (overall current satisfaction with partner) fit poorly with the factor structure, while at the second administration, the second item (our relationship is very stable) fit poorly. Possible implications of the results are discussed.
