Body image disturbance has long been recognized as a core feature of eating disorders and body dysmorphic disorder, but researchers have traditionally treated it as a multidimensional phenomenon without fully mapping how those dimensions connect. A study published in Eating and Weight Disorders – Studies on Anorexia, Bulimia and Obesity examines the perceptual component of body image disturbance, an aspect the authors describe as not well understood, and investigates how it relates to the other dimensions and whether it predicts symptoms of eating disorders and body dysmorphic disorder. The work also suggests that simple perceptual measures carry real predictive power for clinical symptoms.
The research team, led by Lia Marinko and colleagues including Briana L. Kennedy, Fathima Ifadah Imran, Evangeline Meldrum, Laura Dondzilo and Jason Bell, framed body image disturbance around three theorized dimensions: evaluative, behavioral and perceptual. The evaluative dimension captures how people feel about their bodies, such as dissatisfaction or concern. The behavioral dimension covers actions taken in response, such as body checking or avoidance. The perceptual dimension, by contrast, concerns how accurately people estimate the size or shape of their own bodies, an aspect the authors describe as not well understood, particularly in relation to the other two dimensions.
To probe these relationships, the researchers recruited 262 female undergraduate students between the ages of 17 and 25. Participants completed a battery of assessment measures designed to capture body image disturbance across all three dimensions, alongside clinical instruments measuring symptoms of eating disorders and body dysmorphic disorder. This design allowed the team to test both how the perceptual measures related to evaluative and behavioral measures and whether the perceptual measures added anything unique when predicting symptom levels.
The results showed strong relationships overall between most perceptual measures and the evaluative and behavioral measures of body image disturbance. The source reports strong relationships overall between most perceptual measures and the evaluative and behavioral measures; it does not describe the specific pattern of individual women's estimates and reported evaluations and behaviors.
The more striking finding emerged from the multiple regression analyses. Multiple regression analyses showed that several perceptual measures were significant, unique predictors of symptoms related to eating disorders. The predictive value extended to body dysmorphic disorder symptoms as well, although the authors note this relationship was weaker, describing the contribution as significant to a lesser extent in that domain.
These regression findings matter because they suggest the perceptual dimension is not redundant with the more commonly assessed evaluative and behavioral dimensions. The authors conclude that these results reinforce the importance of the perceptual dimension in understanding body image disturbance.
The study’s authors conclude that the results provide valuable insight into the relationship between the three dimensions of body image disturbance and reinforce the importance of the perceptual dimension in understanding the construct. The authors also state that they discuss the study's implications for understanding and addressing eating disorders and body dysmorphic disorder.
Several caveats frame the findings. The sample consisted exclusively of female undergraduate students aged 17 to 25, a narrow demographic that limits generalization to men, older adults, clinical populations or community samples. The study measured participants at a single time point, so the regression analyses identify associations among variables rather than demonstrating that perceptual measures cause symptom development. The abstract classifies the work as Level I, evidence obtained from experimental studies, and the article was published open access on 31 August 2026 as an early-release, peer-reviewed accepted version carrying a permanent DOI, subject to further edits before the final Version of Record appears.
