Eating disorder mental health literacy: What do psychologists, naturopaths, and fitness instructors know?

At present, there are no known studies investigating the eating disorder mental health literacy (ED-MHL) of common frontline health providers such as psychologists, naturopaths, and fitness instructors. Little research also exists around practitioner knowledge for the spectrum of eating disorders. The current study sought to fill these research gaps and comprised 115 health practitioners who completed an online survey. A fictional vignette describing a female (Sarah) experiencing a subthreshold bulimic variant without purging was presented alongside common ED-MHL items. Almost 4 in 10 psychologists, 7 in 10 natural therapists, and 8 in 10 fitness instructors failed to detect a general eating disorder, with the latter two groups more likely to believe the problem was a self-esteem issue. Perceived helpfulness of people and interventions varied from best practice clinical guidelines, with physical/medical risk management not prioritized, pharmacotherapy viewed poorly, and doctors seen as one of the least helpful people. Although Sarah's problem was seen as severe and highly common (which may speak to the volume of undetected eating disorders), alarmingly 36.7% of fitness instructors viewed her predicament as desirable given weight lost. This novel study highlights the need for specific training interventions to improve health practitioners' ED-MHL, particularly around atypical eating disorder presentations, which may facilitate earlier detection and help-seeking for evidence-based interventions rather than expenditure on unhelpful or even harmful treatments, leading to improved community health and lives saved.
