Autoapresentação perfeccionista, imagem corporal e a mediação da autocompaixão

Abstract

The present dissertation aims to investigate the relationship between Perfectionist Self-Presentation, body image and the mediating effect of self-compassion. For this, three studies were carried out, one theoretical and two empirical. In the first, a systematic review was carried out on the psychometric properties of the Perfectionistic Self-Presentation Scale (PSPS). Searches occur in the following databases: Scopus, Web of Science, Wiley Online Library, GALE, SAGE, SpringerLink, DOAJ, ScienceDirect, PubMed, PsycArticles and ASP. The search and selection of studies took place in pairs and independently. In the end, 276 studies were identified, completed as selection and eligibility steps, six were included in the review. In examining the psychometric properties, the focus was on the validity checks passed on the internal structure and relationships with external measures. The results appreciated divergences regarding the internal structure of the PSPS; and, correlations of moderate magnitude with external variables. In the second, the cross-cultural adaptation of the Perfectionistic Self-Presentation Scale into Brazilian Portuguese was performed. The study examined the instrument's psychometric properties with a sample of 708 universities from public and private institutions in the state of Rio de Janeiro. By means of Confirmatory Factor Analysis, one-dimensional models, three correlated factors, hierarchical and two-factor models were tested. The results showed good adjustments for the bifactor model, but the examination of the complementary indices recommended unidimensionality for the measure. The PSPS was invariant between women and men and also between university students from public and private institutions. In addition, the scale showed evidence of convergent validity through positive breathing moderately with a measure of perfectionism related to physical appearance. In the third study, the mediating effect of self-compassion on the relationship between Perfectionist Self-Presentation and body image was investigated. Using data from a university sample of public and private institutions, Student's t-test was performed for independent references, bivariate correlations and Multivariate Multiple Linear Regression Analysis in the PROCESS macro, executing the simple mediation model. The results showed that there are no differences between the scores of university students from public and private institutions, and also that the correlations between the variables were expressions. Finally, in the mediation analysis, the mediating effect of self-compassion on the relationship between Perfectionist Self-Presentation and satisfaction with body image was confirmed. The findings of this study indicate that promoting self-compassion can reduce the effects of Perfectionist Self-Presentation on satisfaction with body image.
