Research suggests that some people may experience an obsession with healthy eating, which has been referred to as Orthorexia Nervosa (ON). However, it is not clear whether such a condition exists and, if so, whether it is different from other conditions such as one of the recognised eating disorders (EDs). In order to determine whether this is the case, more research needs to be conducted to investigate whether ON differs from other eating disorders in a meaningful way. This study, by collecting self-report questionnaire data and administering two Choice Based Conjoint analysis tasks, will allow for comparisons to be made between ON and EDs. The study will also allow for comparisons to be made between ON and other forms of normative healthy eating to determine whether ON represents a pathological variant of healthy eating.
Eligible participants will be people aged 18 years old and above who are either (1) individuals who have a strong focus on healthy eating based on the screening measure; (2) individuals who currently have or have had an eating disorder; (3) individuals with no personal experience with eating/shape or weight concerns but who need to exclude certain foods from their diet based on medical, ethical or religious reasons; or (4) individuals who have no personal experience with eating, shape or weight concerns. A total of approximately 400 participants will take part in the study.
