Abstract
Though people report idiosyncratic desires for particular traits in an ideal romantic partner, few studies have examined whether these ideals predict important long-term relationship outcomes. The present 3.5-year longitudinal study of newlywed couples used survival analysis to investigate whether the match between participants’ ideal preferences and the traits they perceive in their partner predict the likelihood of divorce. Results depended entirely on whether the match was conceptualized as a match in level (e.g., high ideal preference for a trait with the presence of the trait in the partner) or in pattern (e.g., the within-person correlation of ideals with a partner’s traits across all traits). The match between the pattern of ideals and traits negatively predicted divorce with an effect size larger than most established divorce risk factors. However, the match in level was unrelated to divorce, suggesting that perspectives emphasizing ideals for the level of traits may encounter predictive validity problems.
