Abstract
BackgroundThis study aimed to assess differences in Quality of Life (QoL) across eating disorder (ED) diagnoses, and to examine the relationship of QoL to specific clinical features.Results199 patients with a diagnosed ED completed the Clinical Impairment Assessment (CIA) [Cognitive Behavior Therapy and Eating Disorders, 315–318, 2008] and the Eating Disorders Examination (EDE) [Int J Eat Disord 6:1–8]. Differences between diagnostic groups were examined, as were differences between restrictive and binge-purge subtypes.CIA scores and EDE scores were positively correlated and higher in groups with binge-purge behaviours. CIA scores were not correlated with BMI, illness duration or frequency of bingeing/purging behaviours, except in the binge-purge AN group, where CIA scores negatively correlated with BMI.ConclusionsPatients with EDs have poor QoL and impairment increases with illness severity. Patients with binge/purge diagnoses are particularly impaired. It remains unclear which clinical features best predict the degree of impairment experienced by patients with EDs.
Highlights
This study aimed to assess differences in Quality of Life (QoL) across eating disorder (ED) diagnoses, and to examine the relationship of QoL to specific clinical features
Patterns of diagnostic differences are inconsistent across studies, with some studies finding no significant differences between diagnostic groups [7,8], some reporting lower QoL in individuals with anorexia nervosa (AN) than bulimia nervosa (BN) [9,10,11], and others reporting higher QoL in AN [12,13]
It is notable that studies finding less impairment in AN have tended to use generic, rather than ED specific measures of QoL, which - as has been hypothesized - may be less sensitive to certain aspects of impairment associated with these disorders [14]
Summary
This study aimed to assess differences in Quality of Life (QoL) across eating disorder (ED) diagnoses, and to examine the relationship of QoL to specific clinical features. The assessment of Quality of Life (QoL) in people with eating disorders (EDs) has been subject to considerable research interest. Studies in EDs have indicated significantly reduced QoL in this patient group, to a degree that is comparable with QoL findings in various other serious. Patterns of diagnostic differences are inconsistent across studies, with some studies finding no significant differences between diagnostic groups [7,8], some reporting lower QoL in individuals with anorexia nervosa (AN) than bulimia nervosa (BN) [9,10,11], and others reporting higher QoL in AN [12,13]. There is some evidence that individuals with bingeing and/or purging forms of AN are more impaired than individuals with restrictive
