The study investigates the reliability and validity of the Turkish Dyadic Adjustment Scale (DAS). Scores of the DAS were studied for its reliability and validity. The sample consisted of 264 married individuals. The alpha coefficient for the DAS was .92. Computed split-half reliability coefficient was .86. The DAS correlated .82 with the Locke-Wallace Marital Adjustment Test. The original factor structure of the DAS was replicated in the present study. In general, the data indicated that the DAS provides a reliable and valid measure of marital adjustment for a Turkish sample.
