Conceptual replication of Seo (2008), “Self-efficacy as a mediator in the relationship between self-oriented perfectionism and academic procrastination”


Słowa kluczowe:

personality, replication, preregistration, procrastination, perfectionism



Self-oriented perfectionism is the tendency to set high standards for oneself and evaluate one’s behaviour accordingly. Based on a study of 692 students in Korea, Seo (2008) reported finding a negative relationship between self-oriented perfectionism and academic procrastination – i.e., the tendency to procrastinate on academic tasks. Furthermore, Seo reported that this relationship was completely mediated by self-efficacy. Seo’s study has been influential in the literature but to our knowledge has not yet been independently replicated. In this study we report a preregistered conceptual replication testing five hypotheses based on Seo’s key findings.

Participants and procedure

A detailed preregistration (including data processing and analysis syntax) was lodged in advance of data collection at Participants were 575 students recruited from OECD countries using Academic procrastination was measured via an adapted version of the Procrastination Assessment Scale – Students, while self-oriented perfectionism was measured via the 5-item self-oriented perfectionism subscale of the Big Three Perfectionism Scale. Self-efficacy was measured via the New General Self-Efficacy Scale. Both ordinary least squares regression and structural equation modelling were used to test hypotheses.


We found no evidence of a bivariate relationship between self-oriented perfectionism and academic procrastination in either set of analyses. However, we did find evidence of a small and negative indirect effect of self-oriented perfectionism on academic procrastination via self-efficacy.


We were only able to partially replicate Seo’s key findings, having found no evidence of a negative relationship between self-oriented perfectionism and academic procrastination.
