Objective To investigate the severities and correlated factors of psychological disturbances among Beijing Psychological Support Hotline callers. Methods From January 2020 to June 2020， all the callers of Beijing Psychological Support Hotline were recruited. Demographic characteristics， psychological disturbances （including psychological distress， hopelessness， and depression）， and socio-psychological characteristics of the callers were collected by operators. Multivariable Logistic regression was used to select the correlative factors of the severities of psychological disturbances. Results Among the 9 249 recruited callers， 66.8% （6 174/9 249） were females， 46.3% （4 279/9 249） were students. Psychological distress， hopelessness， and depression were the top serious problems， with the median scores of 80， 70 and 67 respectively. After demographic variables were adjusted， financial difficulties （OR=1.94， 95%CI：1.48-2.53； OR=1.92， 95%CI： 1.48-2.50） and suicide attempt history （OR=1.79， 95%CI：1.57-2.04； OR=2.32， 95%CI：2.04-2.63） were main correlated factors of the high levels of psychological distress and hopelessness （P＜ 0.01）. Chronic negative life events （OR=2.30， 95%CI：2.04-2.59）， substance misuse （OR=1.99， 95%CI：1.62-2.45） and suicide attempt history （OR=1.97， 95%CI：1.77-2.22） were main correlated factors of severe depression （P ＜ 0.01）. Conclusions The psychological disturbances of Beijing Psychological Support Hotline callers are generally severe. Financial difficulties， suicide attempt histories and chronic negative life events have strong correlations with psychological distress， hopelessness， and depression. The main correlative factors of different psychological disturbances are different.
