During the past 20 years I have worked with eating disorders and I have combined the clinical work with research on eating disorders and perfectionism. My doctoral thesis “Flawless beyond reach and reason – Aspects of perfectionism in eating disorders” examines perfectionism as conceptualized by the Eating Disorder Inventory (EDI) Perfectionism scale and patients’ descriptions of perfectionism. During my years as a psychologist, I have also worked with patients with myocardial infarction and pain in parallel with my psychiatric work. At present I conduct an Randomized controlled trial-study on manual based group treatment, the Affect school, as a complimentary treatment of eating disorders, and also a nine year follow-up study on predictors for long term eating disorders.
