Are you looking for participants for eating disorder research?
Joanna Poppink, Marriage & Family Therapist and Eating Disorder Recovery Specialist runs an excellent website with a wide range of resources available for people struggling with eating disorders. She recently let me know that she has updated the academic and professional eating disorder research page on the site. The new version incorporates a facility for researchers to post descriptions of their research and project needs, including requests for participants. The service is free.
