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). Results also indicate evidence of validity and reliability satisfactorily set aside for the Affective Expression subscale having a lower Cronbach alpha coefficient. The results also indicate strong validity of the scale according to indices of convergent and discriminant validity. Finally, a discussion is presented addressing considerations to be taken into account for using the questionnaire among older couples.
