Échelle d'ajustement dyadique : intérêts cliniques d'une révision et validation d'une version abrégée

Results showed that they were organized according to two dimensions that explain 52% of the variance. The first factor relates to the degree of agreement in couples (DA). Ten items present loadings with this component explaining 32% of the variance. The second dimension, made up of six items, corresponds to the quality of the dyadic interactions (IQ). This factor explains 20% of the variance. The correlation between the scales that were derived from this analysis was found to be r = 0.50 (p < 0.01). The cross-validation analysis performed on the subjects' answers was found to follow the same factorial structure, just as the male and female samples did. Our analyses further highlighted the relevance of a hierarchical structure and consequently, the possibility of calculating a total score. The coefficients of internal consistency were 0.89 for the total scale and the scale of degree of agreement, and 0.75 for the scale of quality of the interactions. As the DAS-16 was strongly correlated with the full DAS version, the possibility of score equivalence was thus confirmed. In conclusion, our results provide a unidimensional structure and a two-dimensional comprehension of marital adjustments. The factors were shown to be stable and similar for sex. Moreover, one of the weaknesses of the original version of the DAS was the lack of independence of the scales. Our version of the DAS allows the identification of factors that are moderately correlated. Finally, one of the originalities of our work is the validation of the abbreviated form that used as indicator the differences between partner interactions within a given couple.
