  1. Correlational data between the BABS [18] and the NBS [19] was used to determine delusional intensity category score ranges: good/fair insight (0–10); overvalued idea (11–15); delusional belief (16 +). Abbreviations: DoI = Illness Duration (years); SoI = Severity of Illness (based on DSM-5 severity specifier); LoS = Length of Stay (days); EDEQ = Eating Disorder Examination Questionnaire (Global Score); BSQ = Body Shape Questionnaire; BISS = Body Image State Survey; CDRS = Contour Drawing Rating Scale (dissatisfaction subscale); BAIS = Body Image Assessment Software (dissatisfaction subscale). *Significant p < 0.05
