Association between accompanying duration and anxiety/depression among family caregivers: a prospective cohort study in China during the COVID-19 pandemic

While some studies have explored family caregivers' anxiety and depression, limited research has been conducted on family caregivers' anxiety and depression caused by the duration of companionship, resulting in an unclear relationship between the length of accompaniment and the psychological well-being of family caregivers. This cohort study was conducted from April 1, 2022, to June 30, 2022 in general surgery. We employed bar graphs and line graphs to illustrate the relationship between accompanying days and anxiety and depression. Additionally, mixed-effects linear regression models were utilized to examine the correlation between accompanying days and the likelihood of anxiety and depression. The study had 207 family caregivers, with 23.5% experiencing anxiety and 13.1% experiencing depression. Anxiety and depression scores peaked on day 9, and the incidence rate was the highest for the third group (≥10 days). Family caregivers in the first group (≤4 days) of companionship had significantly higher anxiety (β=0.27, 95% CI 0.16-0.39,
