Sammanfattning Denna studie, baserad på enkätdata från det nationella kvalitetsregistret RIKSÄT, insamlad mellan 2003-2010, undersökte betydelsen av vikt vid ätstörningsbehandling för svenska kvinnor. Viktgrupper inom diagnoserna anorexi, bulimi, ätstörning utan närmare specifikation samt hetsätningsstörning jämfördes avseende behandlingsutfall. Utfallsmåtten var kvarvarande symtom efter avslutad behandling i form av Hetsätning och kompensatoriska beteenden och Ångest kring mat och vikt, Tillfredsställelse med behandlingskontakt, samt Förändringar i global funktionsförmåga (GAF). Resultatet indikerar samband inom diagnosen anorexi. Underviktiga vid behandlingsslut var mindre nöjda med behandlingskontakten än de med hälsosam vikt och de som förblivit underviktiga var mindre nöjda än de som gått från undervikt till hälsosam vikt. Då området för studien är relativt outforskat föreslår författarna vidare forskning kring betydelsen av vikt i ätstörningsbehandling.    Nyckelord: Ätstörning, Vikt, RIKSÄT             Jonna Juniwik och Elizabeth Torkelsson Examensuppsats i psykologi, 30 hp Handledare: Katja Boersma, Örebro universitet Vårterminen 2011 / Abstract   This prospective study, based on survey data from RIKSÄT collected 2003-2010, examined the importance of weight in eating disorder treatment for Swedish women. Weight groups in the diagnoses of Anorexia, Bulimia, Eating Disorders Not Otherwise Specified and Binge Eating respectively were compared on different treatment outcomes. The outcome measurements were Residual symptoms after treatment, Satisfaction with treatment contact, and Changes in global assessment of functioning. The results indicate a relationship between weight and treatment outcome in the diagnosis of Anorexia and Eating Disorders Not Otherwise Specified. This area of research is to date relatively uncovered by research, which is why the authors suggest further research on the importance of weight in the treatment of eating disorders.Keywords: Eating Disorders, Overweight, Obesity, RIKSÄT   1Psychologist Programme, Master’s thesis.

Introduction: Eating disorders are serious psychiatric disorders that often require specialized care. Associated psychiatric comorbidity is frequent, with the most common comorbid conditions being anxiety and mood disorders. Eriksbergsgården in Örebro is one of Sweden’s specialized eating disorder treatment units.Aim: Primary aims were to describe clinical characteristics of the adult patient group at Eriksbergsgården and to evaluate treatment outcome and patient satisfaction at the one-year follow-up. An additional aim was to examine if factors such as psychiatric comorbidity affected treatment outcome.Methods: This study used data from Riksät and Stepwise, two large-scale Swedish registers for eating disorder treatment. Data for this study was registered into Stepwise and Riksät at Eriksbergsgården between August 2010 and December 2017 and 489 adult patients of both genders constituted the study group. Patient characteristics and DSM-IV axis I psychiatric comorbidity were assessed at the initial evaluation. At the one-year follow-up, treatment outcome and patient satisfaction were evaluated.Results: The most common diagnoses in this patient material were eating disorder not otherwise specified, 56.6 %, followed by bulimia nervosa, 26.4 %. At the initial evaluation, 62.0 % of the patients suffered from psychiatric comorbidity. Of the patients with initial comorbidity, 43.3 % were recovered at the one-year follow-up, compared to 62.8 % of the patients with no initial comorbidity, p=0.021.Conclusion: Our results confirm the previously known fact that psychiatric comorbidity among eating disorder patients is common. Also, the results identify psychiatric comorbidity as a possible factor to have negative effect on the treatment outcome.
