Psychological distress and associated factors of the primary caregivers of offspring with eating disorder during the coronavirus disease 2019 pandemic

Background: The Coronavirus Disease 2019 (COVID-19) is a global pandemic and posed serious challenges in many countries. A number of studies before the COVID-19 pandemic have shown that the primary caregivers of the ED patients are subjected to great burden, psychological pressure, and serious emotional problems. This study aimed to investigate the psychological distress level of the primary caregivers of ED offspring during the COVID-19 pandemic. Methods: From March 6 to April 20, 2020, 378 questionnaires for primary caregivers of ED offspring and 1163 questionnaires for primary caregivers of healthy offspring were collected through an online crowdsourcing platform in mainland China. Valid questionnaires that met the criteria included 343 (90.74%) primary caregivers of ED offspring and 1085 (93.29%) primary caregivers of healthy offspring. Using Propensity Score Matching (PSM), 315 (83.33%) primary caregivers of ED offspring and 315 matched primary caregivers of healthy offspring were included in the statistical analysis. Depression, anxiety, perceived stress and social support were measured by Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Perceived Stress Scale-10 and Social Support Rating Scale, respectively. Results: The rates of depression and anxiety of the primary caregivers of ED offspring were 20.6 and 16.5%, which were significantly higher than those of primary caregivers of healthy offspring (4.1 and 2.2%), all P < 0.001. Regression analysis found that perceived stress, social support, previous or present mental illness, family conflicts during the COVID-19 pandemic had a significant impact on the severity of depression (P < 0.001, P = 0.002, P = 0.041, P = 0.014); Perceived stress, social support, family conflicts during the COVID-19 pandemic and years of education had a significant impact on the severity of anxiety (P < 0.001, P = 0.002, P = 0.002, P = 0.003). Conclusions: During the COVID-19 pandemic, primary caregivers of ED offspring experienced more psychological distress than that of primary caregivers of healthy offspring. ED caregivers with high perceived stress may have higher levels of depression and anxiety. ED caregivers with high social support, no mental illness and no family conflicts may have lower levels of depression. ED caregivers with high social support, no family conflicts, and high years of education may have lower levels of anxiety.
