Objective To assess the mental health status of the pregnant women with missed abor-tion, as well as related influencing factors, and to provide the basis for mental nursing. Methods 100 pregnant women with missed abortion were chosen as the observation group by convenience sampling, while other 100 normal pregnant women as the control group. The mental state of the pregnant women in both groups was evaluated by using symptom checklist-90 (SCL-90), the results of which were then studied in contrast using t test and variance analysis. Results The total scores and the average scores of pregnant women in the observation group were significantly higher than those in the control group. The mental health status of pregnant women with missed abortion was influenced by age, education degree, and the times of pregnancy. Conclusions There are significant mental health problems in pregnant women with missed abortion, to which should be paid much attention. And the psychological counseling should be carried out in time in case of detrimental influences in treatment, rehabilitation, and next pregnancy.
