Understanding the role of perfectionism in adult expectations of dietary restriction and thinness

Abstract

Aims: This study aimed to evaluate the relationship between perfectionism and expectations of thinness and dietary restriction in adults. Methods: This descriptive and cross-sectional study was conducted with adults 18-65 years old. Demographic characteristics and anthropometric measurements were questioned using a questionnaire form. Perfectionism characteristics of individuals were evaluated with “Frost Multidimensional Perfectionism Scale (FMPS)” developed to make a multidimensional assessment of perfectionism, and the findings regarding their expectations from thinness and food restriction were evaluated with the “Thinness and Restricting Expectancy Inventory (TREI) Scale”. Data collection was facilitated using a web-based questionnaire. Those who were not in the appropriate age range and did not tick the “I consent to participate in this study voluntarily” tab were excluded from the study. Results: The study population was 1,376 adults (mean age: 27.42±10.99 years; 74.4% female). The TREI total score showed a weak positive correlation with the FMPS total score (r=0.351, p<0.001), and body mass index (BMI) (r=0.288, p<0.001). In multiple regression analysis, BMI, marital status, and TREI score showed an independent association with the FMPS total score. Male sex, TREI score, fear of making mistakes, and dieting showed independent associations with BMI. Conclusions: Perfectionism is associated with body dissatisfaction, BMI, expectations regarding thinness, and dietary restriction. It is considered an influential personality trait for identifying the risk of developing eating disorders and assessing the treatment process in the future.
