Abstract
PURPOSE: The relationship between autism spectrum disorders (ASDs) and eating disorders (EDs) has been widely studied in the last decades. We aimed to directly compare patients with EDs, individuals with high-functioning ASDs (HF-ASDs) and healthy controls (HC) at measures detecting: (1) symptoms of eating disorders, (2) eating disturbances known to be characteristic of autism. METHODS: Thirty-four patients with EDs, 34 individuals with HF-ASDs and 35 HC, all females, completed the eating attitude test (EAT-26) and the Swedish eating assessment for autism spectrum disorders (SWEAA), two self-report questionnaires assessing, respectively, symptoms and concerns characteristic of eating disorders and ASD-related eating disturbances. RESULTS: At the EAT-26, patients with EDs scored significantly higher than individuals with HF-ASDs, and both of them scored higher than HC (p < 0.05, ηp2 = 0.283). Conversely, at the SWEAA, no differences between individuals with HF-ASDs and patients with EDs emerged (p = 901), but they both scored higher than HC (p < 0.05, ηp2 = 0.247). CONCLUSION: Individuals with HF-ASDs did not seem to reach the same level of EDs symptomatology as patients with EDs. Patients with EDs did not seem to present a different amount of autistic-eating behaviours than subjects with HF-ASDs. Patients with EDs and individuals with HF-ASDs scored higher than HC at both scales. Our results give further preliminary evidence of the overlap between autistic traits and EDs symptomatology, and should be taken into account in the definition of a shared model between EDs and ASDs. LEVEL OF EVIDENCE: Level II; Evidence obtained from controlled trial without randomization.
