This is a research project conducted by an external organisation. It may be of interest to people affected by complex mental health issues. To find out more about the project below, contact the researchers directly.

The main objective of this Australian National University study is to investigate whether Orthorexia Nervosa is a clinical disorder, and if so, whether it is separate from other recognised eating disorders.

The study begins with two tasks: in the first, you will be asked to select your preferred foods from options provided. In the second task, you will be asked to select the person you would most like to be based on a range of different personal characteristics. Seven questionnaires follow, which cover eating, shape and weight concerns, your mood, and any difficulties you may be experiencing in functioning in your everyday life.

The study should take no more than 60 minutes to complete.

You can take part if you are aged 18+ and if you:

  • have a strong focus on healthy eating based on the screening or
  • currently have or have ever had an eating disorder or
  • have no personal experience with eating, shape or weight concerns but need to exclude certain foods from your diet based on medical, ethical or religious reasons or
  • have no personal experience with eating, shape or weight concerns

All participants will be offered the opportunity to enter a draw to win one of four $50 Westfield gift vouchers. If you choose to enter, you will need to provide your email address at the end of the survey. Your contact details will not be linked to your responses from the questionnaires. 

The study is open now and will run until 30 August 2021. Click here to take part.
