Preregistered replication of Stoeber (2012): Dyadic perfectionism in romantic relationships

The present study reports a preregistered replication of a study by Stoeber (2012) investigating the relationships between dyadic perfectionism, relationship satisfaction and longterm commitment. Our study included 71 couples in a dyadic design that measured actor and partner effects using multilevel regression analyses. The findings were mixed: We were able to reproduce some of the relationships reported by Stoeber, some failed to reproduce, and some new relationships were found. Participants who perceived that their partners had perfectionistic expectations of them did tend to report lower relationship satisfaction and longterm commitment. However, there was no evidence of a relationship between the degree to which participants self-reported having perfectionistic standards towards their partners and their partners’ relationship satisfaction and longterm commitment.
