The present investigation examined the effect of perfectionism on metacognitive listening strategy (MLS) use through the components of self-efficacy (initiative, effort, and persistence) among a sample of 117 Iranian English as a Foreign Language university students. Cluster analysis was utilized to identify the perfectionistic clusters. The resulting analysis yielded a three-cluster solution (adaptive, maladaptive, and non-perfectionist). Multicategorical multiple mediation analysis was then used to explore the relative direct, indirect, and total effects and to test the postulated hypotheses of the study. Results indicated that adaptive perfectionism was associated with higher levels of effort and persistence, leading to greater MLS use. Regarding the initiative subscale, no significant differences were observed among the three perfectionist groups. Maladaptive perfectionists showed high levels of effort investment but not persistence. Mediation analysis did not support self-efficacy components as the mediators of the relationship between perfectionism and MLS use. Among self-efficacy components, only effort exerted a positive effect on MLS use. Results are discussed in terms of implications for future research and classroom practice.
