Objective: Eating disorders are one of the deadliest mental health conditions, yet most individuals with eating disorders never receive treatment. Previous research has explored barriers to treatment among individuals diagnosed with eating disorders, but little is known about general adolescent and emerging adult perceptions of eating disorders, as compared to other mental health illnesses, a population at greatest risk for developing an eating disorder, and a population that may be important sources of information or support for peers.Method: A sample of adolescents and emerging adults aged 14-24 years (mean age 19 years) from MyVoice, a national text-message-based cohort (53% female, 38% male, 9% other, race/ethnicity 63% White, 10% Black or African American, 13% Asian, 9% Mixed Race, and 5% Other) provided open-ended responses to questions on the severity of eating disorders as compared to other mental health diagnoses, others' perceptions of eating disorders and potential treatment barriers. Responses were collected using a secure online platform and analyzed using content analysis.Results: Among respondents (n = 792/1283), 91% felt that eating disorders were a mental health condition and 65% felt that eating disorders were as serious as other mental health conditions, while 21% said they were more serious than other mental health conditions. Responses to questions related to perception and barriers illustrated that beliefs of eating disorders involve blame, stigma, and overall lack of understanding.Discussion: Findings from this study illustrate that there is a lack of understanding around eating disorders that could be addressed in youth-focused initiatives.Public Significance: Adolescents and emerging adults understand that eating disorders are severe mental illnesses that are not taken seriously by others, especially in comparison with other mental health diagnoses. Adolescents and emerging adults report that individuals with eating disorders are blamed for their condition and face shame and stigma. The lack of understanding around eating disorders should be addressed in youth-focused prevention initiatives.
