Conceptual replication of Seo (2008) "Self efficacy as a mediator in the relationship between self oriented perfectionism and academic procrastination"
Self oriented perfectionism is the tendency to set high standards for oneself and evaluate one's behaviour accordingly. Based on a study of 792 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 found that this relationship was completely mediated by self efficacy. Seo's study has been influential in the literature but has not been independently replicated. In this study we report a conceptual replication utilising 575 students from OECD countries and a cross sectional survey design. A detailed preregistration (including data processing and analysis syntax) was lodged in advance of data collection at https:/osf.io/xfvd8. 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 academic procrastination in either set of analyses, meaning that we were unable to reproduce one of Seo's two key findings. However, we did find evidence of a small and negative indirect effect of self oriented perfectionism on academic procrastination via self efficacy, reproducing part of the mediation model reported by Seo.
