Ideal Standards, Acceptance, and Relationship Satisfaction: Latitudes of Differential Effects.
Level 3 - non-randomized controlled study
Three-year prospective longitudinal observational study of newlywed couples.
PubMed 29033876 · doi:10.3389/fpsyg.2017.01691
What was done
Researchers analyzed a 3-year longitudinal dataset of heterosexual newlywed couples to determine whether the association between partner ideal-perception consistency and relationship outcomes levels off above a certain threshold. Consistency was evaluated using pattern correspondence (within-person correlation across attributes) and mean-level match (discrepancy between ideal scores and perceived partner scores) to predict partner acceptance and relationship satisfaction.
What was found
The abstract provides no numerical data, statistics, or effect sizes. Pattern correspondence had no association with partner acceptance, but exhibited a positive linear/exponential association with relationship satisfaction. Mean-level match was positively associated with an actor's partner acceptance and relationship satisfaction up to the threshold where perceived partner scores equaled ideal standards. Partner effects showed no consistent pattern.
Why it matters
The study suggests that matching romantic ideals enhances partner acceptance and relationship satisfaction primarily up to the point of meeting expectations, with diminishing returns once ideals are exceeded.
Limits
The abstract omits key methodological details, including the sample size, response rates, attrition over the 3-year follow-up, and specific quantitative estimates. The sample was restricted to heterosexual newlyweds, limiting generalizability to other relationship structures or long-term partnerships.
