Does socially prescribed perfectionism predict daily conflict? A 14-day daily diary study of romantic couples using self- and partner-reports

People high in partner-specific socially prescribed perfectionism view their romantic partners as rigidly demanding perfection of them. Case histories and theoretical accounts identify conflict with romantic partners as a recurrent, core interpersonal problem for people high in partner-specific socially prescribed perfectionism. Most research in this area uses mono-source, cross-sectional designs. The present study advances this research by studying perfectionism and conflict in 226 romantic couples using a 14-day daily diary design involving self- and partner-reports. As hypothesized, self- and partner-reports of partner-specific socially prescribed perfectionism correlated moderately. Results for men were consistent with hypotheses: Self- and partner-reports of partner-specific socially prescribed perfectionism predicted changes in self- and partner-reports of conflict, even after controlling for reassurance-seeking and previous day's conflict. Contrary to hypotheses, reassurance-seeking was a better predictor of conflict for women. Results indicate men high in partner-specific socially prescribed perfectionism engage in self-defeating interpersonal behaviors. They are over concerned about-yet in daily conflict with-their partners.
