Assessing the Quality of the Dyadic Relationship in First-Time Parents: Development of a New Instrument

Abstract

The purpose of this research was to psychometrically evaluate the Dyadic Adjustment Scale (DAS), modified for use with new, first-time parents by extending the items of communication, sensuality, and sexuality. A total of 820 Swedish respondents, 6 months after the birth of their first child, participated in the study. Psychometric evaluation was conducted with factor analysis. The obtained factor structure was tested with multitrait analysis program. Thirty-three itemswere found to fit into a five-factor solution, explaining 50% of the total variance. Descriptive data revealed thatmost new parentswere satisfied with their intimate relationship in general, but dissatisfied with their sexual lives. Themodified DAS, now called the Quality of Dyadic Relationship Instrument includes 33 items and seems to be a useful, updated measurement for assessing quality of the intimate relationship in new first-time parents.
