Screening for marital and relationship discord.

Based on recent findings suggesting that marital discord is taxonic (i.e., that couples in discordant relationships differ qualitatively, and not just quantitatively, from couples in nondiscordant relationships), this study was designed to develop a brief screening measure for detecting the relationship discord taxon. A national, representative sample of 1,020 married couples completed the Marital Satisfaction Inventory--Revised. Data from this sample were used to create a 10-item screening measure. Using the cut scores from the original study that found evidence of taxonicity as a point of reference, the 10-item screen demonstrated good diagnostic performance in assessing the relationship discord taxon. Taxon classification based on the brief scale demonstrated good short-term stability. The scale is easily administered and scored, making it appropriate for use in clinical and research settings.
