Objective To understand the mental health status of community health care workers, assess the effect of psychological intervention measures, and find effective measures to improve the mental health status of community health care workers.Methods With the help of Symptom Checklist SCL-90, we firstly carried out baseline survey on community medical staff mental health; then retested that at 3, 6 and 9 months later. Thus, we could assess the effect of psychological intervention. According to the results of the medical staff working pressure test questionnaire, we could develop targeted psychological intervention measures and adopt prompt adjustment.Results Community health care personnel SCL-90 evaluation score and 7 factors scores(physical,forced,interpersonal sensitivity,anxiety,hostility,terror,and paranoia) were higher than the national norm(P<0.05);after comprehensive intervention in the 9 months follow-up,the SCL-90 evaluation score was decreasing gradually.After intervention for 6 months,except for the interpersonal sensitivity factor,SCL-90 total scores and the other factor scores tend to normal levels, to compare the national norm, there was no statistical significance in differences (P<0.05). 9 months later, the scores of interpersonal sensitivity also return to normal levels.Conclusion The mental health status of community health care workers was lower than the national norm,the comprehensive intervention may improve their mental health level, and the experiment showed that the intervention should be no less than 6 months.
