Psychometrical Properties of the Dyadic Adjustment Scale for Measurement of Marital Quality with Italian Couples

Developed by Spanier in 1976, the Dyadic Adjustment Scale (DAS), a 32 items self-report tool, to assess couple satisfaction and to evaluate how each partner within the couple perceives his or her relationship. The aim of the study is to evaluate the psychometric properties of the DAS in the Italian context. The total sample size was 896 participants (M = 44.54; SD = 10). Exploratory and confirmatory factor analyses were performed in order to test the dimensionality of the analysis tool and these demonstrated the reliability of the four factors. The model, representing four dimensions of dyadic adjustment, was confirmed.
