Perfectionistic Self-Presentation Scale in Ecuador: psychometric properties and latent mean differences across genders

Introduction: This paper aims to examine the psychometric properties, i.e., validity, reliability, factorial invariance, and latent mean differences based on gender, of the Perfectionistic Self-Presentation Scale, PSPS, in the Ecuadorian context. Method: A sample consisting of 597 Ecuadorian undergraduates participated in the study. Results: Confirmatory Factor Analysis supported a 14-item and three-dimensional model of the scale: Perfectionistic Self-Promotion, Nondisplay of Imperfection, and Nondisclosure of Imperfection. This model presented configural; measurement, i.e., metric, strong, and strict; as well as structural invariance across genders. Discriminant validity was observed by analysing correlations between PSPS factors and perfectionism traits. Males exhibited higher latent means of Perfectionistic Self-Promotion and also Nondisplay of Imperfection than females. Conclusions: The Spanish-translated and brief version of the PSPS represents a reliable and valid tool for assessing perfectionistic self-presentation in Ecuador.
