The definition and measurement of autistic identity when studying eating disorder symptoms

While the Bradley et al. paper brought up an interesting question regarding the relationship between autistic identity and eating disorders, there are concerns with the assumptions and design of this study. This article concludes that autistic identity has no connection to potential eating disorder symptom severity. However, the psychometric tool used, the Social Identity Scale, is missing key aspects of autistic identity found in other tools. In addition, the tool used is not validated in autistic adults.Lay AbstractA recent paper by Bradley et al. concluded that there is no relationship between autistic identity and eating disorder symptoms. However, the survey tool used to assess autistic identity of its participants did not include key components needed to arrive at this conclusion. Variations of autistic identity that would need to be considered are manifold. Some of these facets to consider in a survey assessing autistic identity would be whether or not autism is a source of pride, traits are thought to be steadfast or changeable, stigma is felt, and whether they should perform camouflaging behavior. This is important because eating disorder symptoms can be affected by these differences. For example, changeability and autistic pride have been thought to affect eating disorder symptoms. This research can be accomplished through other psychometrically validated surveys such as the Autism Spectrum Identity Scale, which include these features in the survey development. So, the Autism Spectrum Identity Scale or like measure would need to be used before reaching the conclusion of this recent Bradley et al. paper. In addition, the Social Identity Scale used in the Bradley et al. paper has not been validated in an autistic adult sample, which makes it not the ideal survey for the research question as well.
