Patterns of disordered eating behavior, adaptive and maladaptive perfectionism and impulsivity in early adolescents
Abstract
In this study, latent profile analysis (LPA) was used to identify naturally occurring patterns or profiles of maladaptive and adaptive perfectionism, impulsivity, and disordered eating (DE) in early adolescence (111 boys, 138 girls; M age = 13.6 years). Profile membership at age 13 was used to examine disordered eating patterns assessed at ages 11 and 12, providing insights into how symptoms had developed prior to profile formation. Using LPA, we identified five profiles: (1) high functioning (2), maladaptively impulsive (3), anxious-avoidant (4), maladaptively perfectionistic, and (5) maladaptively impulsive-perfectionistic. The maladaptively perfectionistic profile showed the highest levels of dieting, preoccupation with food, and body concerns as well as perceived sociocultural pressure to be thin, followed by the maladaptively impulsive-perfectionistic profile. Analyses of earlier DE patterns indicated that the anxious-avoidant profile consistently showed the lowest BMI and highest perceived pressure to eat, both at age 13 and at earlier assessment points, suggesting possible feeding-related difficulties. The findings confirm that maladaptive and adaptive perfectionism, impulsivity, and BMI are jointly associated with the development of DE in early adolescence, demonstrating that considering these traits together yields greater explanatory value than focusing on any single factor alone. While identifying general risk factors is essential, differentiating…
