Unique contributions of individual eating disorder symptoms to eating disorder-related impairment

Impairment due to eating disorder pathology: Identifying the cut‐off score on the Clinical Impairment Assessment in a clinical and community sample

“…10 A cutoff of 16.0 has since been adopted as a threshold for classification in several studies. 6,11,12 As noted by Bohn et al, 4 however, "a limitation of the study of discriminant validity was the fact that no CIA data on healthy controls were used" (p. 1109). No study has since replicated the original findings by Bohn et al 4 This is despite the clear relevance for screening and clinical purposes, as well as the value of such data to discern the degree of impairment associated with eating disorder pathology in the general population, which may be transient with minimal impact, versus the level of impairment associated with treatment-seeking.…”

“…This threshold was identified as the optimal cut‐off to distinguish caseness between ill versus newly recovered patients, all of whom had participated in a transdiagnostic treatment trial for cognitive‐behavior therapy (CBT) . A cut‐off of 16.0 has since been adopted as a threshold for classification in several studies . As noted by Bohn et al, however, “a limitation of the study of discriminant validity was the fact that no CIA data on healthy controls were used” (p. 1109).…”

Eating Disorder Examination Questionnaire (EDE-Q) and Clinical Impairment Assessment (CIA): clinical norms and functional impairment in male and female adults with eating disorders

“…Although the CIA was developed as a supplement to the EDE-Q, and should be used in tandem (2,24) there are surprisingly few studies investigating the association between ED symptoms and functional impairment. To the authors' knowledge, merely one previously published study has investigated the impact of ED psychopathology (as assessed using the EDE-Q) on psychosocial impairment (as assessed using the CIA) (25). Due to the lack of research on this topic, we know little about how the observed impairment in EDs compares between different ED diagnoses, and whether certain ED symptoms have a greater impact on impairment compared to others.…”

Perfectionism, emotion dysregulation, and affective disturbance in relation to clinical impairment in college-age women at high risk for or with eating disorders

“…Several studies have examined the contributions of individual ED symptoms and body mass index on impairment (Bamford & Sly, 2010; Hovrud & De Young 2015; Mond, Hay, Rodgers, Owen, & Mitchell, 2006); however, few studies have closely evaluated the impact of psychosocial factors on clinical impairment in ED samples. It is crucial to identify which factors are contributing to the most severe distress, as well as examine the specific combinations of psychosocial factors that may be particularly impairing to those with EDs.…”
