Validating the Danish version of the Eating Disorder Quality of Life Scale (EDQLS) in anorexia nervosa.

PURPOSE: The aim of this study was to explore the factor structure of the Danish translation of the eating disorder quality of life scale and evaluate the internal reliability and convergent validity of the scale in a Danish cohort of women with AN. METHODS: The total sample comprised 211 patients diagnosed with anorexia nervosa age 13-40 years. Patients completed questionnaires assessing eating disorder psychopathology, physical and social functioning, and well-being. RESULTS: Factor analyses were not able to support the current division of the scale into 12 factors. We found excellent internal consistency of the eating disorder quality-of-life scale total score. We found relevant associations between quality of life and pre-determined variables. CONCLUSION: This study supports the use of the total score of the eating disorder quality of life scale in assessing quality of life in patients with anorexia nervosa. However, future studies should explore the factor structure of the scale further. LEVEL OF EVIDENCE: III: Evidence obtained from cohort or case-control analytic studies.

Explanatory Factors for Disease-Specific Health-Related Quality of Life in Women with Anorexia Nervosa.

A better understanding of explanatory factors for disease-specific health-related quality of life (HRQoL) in anorexia nervosa (AN) could help direct treatment providers to aspects of the most relevance for patient wellbeing and recovery. We aimed to investigate whether factors associated with HRQoL are the same for women with AN and normal-weight controls. The participants in this study were women with AN recruited from specialized eating disorder centers in Denmark and healthy, normal-weight controls invited via online social media. Participants completed online questionnaires on medical history, disease-specific HRQoL (Eating Disorders Quality of Life Scale, EDQLS) and generic HRQoL (SF-36), eating disorder symptomatology, depression, psychological wellbeing, and work and social adjustment. Questionnaires were fully completed by 211 women with AN (median age 21.7 years) and 199 controls (median age 23.9 years). Women with AN had poorer scores on all measures, i.e., worse HRQoL, psychological health, and work/social functioning. Eating disorder symptomatology affected EDQLS score in both groups, but poorer HRQoL in women with AN was also significantly associated with worse scores on bulimia, maturity fears, depression, vitality, and with older age. The factors investigated together explained 79% of the variance in EDQLS score. Management of disordered self-assessment and thought processes may be of particular importance to women with AN. Greater emphasis on these aspects alongside weight gain could enhance patient-clinician alliance and contribute to better treatment outcomes.

Time trends in treatment modes of anorexia nervosa in a nationwide cohort with free and equal access to treatment.

BACKGROUND: Treating patients with anorexia nervosa (AN) remains a major challenge. The choice between an inpatient or an outpatient care setting is an essential issue for the patients and for their relatives with major health economic implications. However, health services-related studies are lacking. The present study was a descriptive exploration of time-trends in treatment modes of patients with free and equal access to health services. METHODS: The study was based on a nationwide cohort of patients diagnosed for the first time with AN, each followed for 5 years in the registers covering the years 1994-2018. The per patient number of hospital admissions, cumulated number of days of hospitalization and number of outpatient visits during the first 5 years after initial diagnosis were considered. RESULTS: The cohort of patients with AN with at least 5 years of follow-up amounted to N = 7,505. A clear trend was observed in the per patient five-year cumulated number of inpatient days, decreasing by 6% per year after adjustment for age at diagnosis, parental mental diagnosis, and family income. The five-year number of hospital admissions after initial diagnosis decreased by 2% per year, while no trend was observed for outpatient visits. CONCLUSIONS: The per patient number of hospitalizations and cumulated days of hospitalization during 5 years after diagnosis were reduced for patients initially diagnosed with AN while there was no change in the number of outpatient visits. The factors contributing to these changes of treatment modes over time are in need of further study.
