Dyadic Adjustment Scale: a validation study among older French-Canadians living in relationships.

The principal objective of this study, the first of its kind to use this population, is to describe the factor analysis and validity of the Dyadic Adjustment Scale (EAD) among 895 French Canadian seniors living as couples. A confirmatory factor analysis was carried out using structural equation modeling. Results support Spanier's hierarchical model questionnaire (1976).

Marital functioning and psychological distress among older couples over an 18-month period.

Many authors have underlined the existence of a negative association between marital functioning and psychological distress. However, little is known about the direction of this association over time among older couples. This study examined the relation over time between psychological distress and marital functioning among 394 community-dwelling couples.
