The COVID-19 lockdown has had a significant impact on mental health. Patients with eating disorders (ED) have been particularly vulnerable. (1) To explore changes in eating-related symptoms and general psychopathology during lockdown in patients with an ED from various European and Asian countries; and (2) to assess differences related to diagnostic ED subtypes, age, and geography. The sample comprised 829 participants, diagnosed with an ED according to DSM-5 criteria from specialized ED units in Europe and Asia. Participants were assessed using the COVID-19 Isolation Scale (CIES). Patients with binge eating disorder (BED) experienced the highest impact on weight and ED symptoms in comparison with other ED subtypes during lockdown, whereas individuals with other specified feeding and eating disorders (OFSED) had greater deterioration in general psychological functioning than subjects with other ED subtypes. Finally, Asian and younger individuals appeared to be more resilient. The psychopathological changes in ED patients during the COVID-19 lockdown varied by cultural context and individual variation in age and ED diagnosis. Clinical services may need to target preventive measures and adapt therapeutic approaches for the most vulnerable patients.

Objective: Medication is commonly used in anorexia nervosa (AN) despite largely missing high grade evidence. Olanzapine (OLZ) is the best‐evidenced substance used off‐label in this group, with conflicting outcome regarding BMI, clinical and safety parameters. Therefore, it is important to strictly assure quality of treatment with OLZ in AN by using 'Therapeutic Drug Monitoring' according to AGNP‐guidelines, including serum levels and adverse drug reactions (ADRs) to support safety for adolescents with AN and attempt to generate an initial age‐ and disorder‐specific therapeutic reference range. Method: Sixty‐five adolescents with AN (aged 10–18) treated with OLZ (98% female; 97.5% AN‐restricting‐type) were prospectively observed, ADRs reported, and correlations between dosage and serum levels measured at trough level were calculated, a preliminary therapeutic range defined. Results: Mean dosage of OLZ was 8.15 (SD: 2.91) mg and 0.19 (SD: 0.07) mg/kg respectively, average concentration was 26.57 (SD: 13.46) ng/mL. Correlation between daily dosage/dosage per kg and serum level was 0.72 (**p < 0.001)/0.65 (**p < 0.001), respectively. ADRs with impairment were rare (6.3%). 75% improved clinically (CGI). BMI increased significantly by 1.5 kg/m2 (t = 10.6, p < 0.001). A preliminary therapeutic reference range is 11.9 and 39.9 ng/mL. Conclusions: OLZ in the hands of specialists is a well‐tolerated and safe treatment adjunct for adolescents with AN. Highlights: Olanzapine in adolescents with anorexia nervosa is a safe and well‐tolerated adjunct to a multidisciplinary inpatient treatment approach using therapeutic drug monitoring.Correlations of dosage and serum levels are high.A preliminary disorder‐ and age‐specific reference range was successfully defined for the first time.

Objective: To investigate acceptance, reliability, convergent validity, factor structure and sensitivity to change of a German translation of the Caregiver Skills (CASK) scale measuring skills related to caring for patients with eating disorders. Methods: Two hundred and thirty‐three parents (76% female) of adolescent patients (mean age 15.1) with anorexia nervosa (AN) completed the 27 items of the CASK. We calculated item/scale characteristics, internal consistencies and bivariate correlations with other measures of caregiving burden. We evaluated goodness‐of‐fit of the 6‐factor model using confirmatory factors analysis and explored the sensitivity to change following two skills‐based trainings. Results: The fit of the 6‐factor model was acceptable (Root Mean Square Error of Approximation: 0.077, Standard Root Mean Square Residual: 0.080). Cronbach's alpha was excellent for the total (.94) and acceptable for all subscales (0.73–0.85). The total CASK score was 68.04 (max. 100) showing relatively high self‐rated caregiver skills. Non‐completion rates of most items were low (<3%) indicating high acceptance. Convergent validity was found with measures of psychological distress, depression, anxiety and expressed emotion. The total score significantly increased following an 8‐week workshop/online skills training (d = 0.70) and a 2‐day multi‐family intervention (d = 0.47). Discussion: The German CASK version is a useful instrument to assess caregiver skills in parents of patients with AN and to evaluate outcomes of skills‐based trainings. Key points: This study provides the first translation and evaluation of a German version of the Caregiver's skills scale (CASK)The CASK showed high acceptance across caregivers, good internal consistencies of the total and subscales and acceptable fit of the 6‐factor modelCaregiver's skills as measured with the CASK improved with medium‐to‐high effect sizes following skill‐based training/multi‐family therapy based on the cognitive interpersonal maintenance model of eating disorders [ABSTRACT FROM AUTHOR]
