Validation of "Dyadic Adjustment Scale" (DAS)

The existing Russian-language tools for investigating subjective satisfaction with marital relations are outdated and do not have data on their psychometric verification. In addition, most of them are not authoring methods, but are a compilation of several translated foreign psychometric tools with different conceptual models and justifications. Therefore, today there is a marked deficit of adapted and validated modern methodological tools for measuring the level of well-being of marital relations in a Russian-language sample. Object of study: Validity of the tool "Scale of mutual adaptation in a pair" DAS (Dyadic Adjustment Scale). The subject of the study: internal consistency (consistency), constructive validity. The purpose of the study: an empirical evaluation of the Russian version of the "Scale of mutual adaptation in pairs" (DAS). The general hypothesis: The questionnaire "Scale of mutual adaptation" DAS is valid for the Russian-speaking sample. As an important result of this study, it should be noted the establishment of a three-factor structure of the Russian-language version of the "Scale of mutual adaptation" DAS. The composition of the points of the selected scales is close to the original, in addition, the selected scales and the instrument as a whole have high reliability indicators of both internal consistency and split reliability. Also, the hypothesis H2 was fully confirmed in the paper, that scale factors have high internal consistency within the instrument; hypothesis H3 on the availability of acceptable construct validity and hypothesis H4 on the availability of acceptable external validity in the questionnaire.
