To investigate the status of negative emotion and social support of women with recurrent spontaneous abortion (RSA), to analyze the correlation between the negative emotion and social support, and to study the influencing factors of the negative emotion.Methods: 292 women with RSA were selected as the investigation object.The general information questionnaire, self rating anxiety scale (SAS), self rating depression scale (SDS), and social support rating scale (SSRS) were used to collect social demographic information, and to evaluate the negative emotions and social support, and to study the correlation between the negative emotion and social support.The related influencing factors of the negative emotion were analyzed.Results: The SAS score of the women was 50.65±2.57 points, the anxiety rate of the women was 54.7%, and the SDS score of the women was 52.03±4.28, and the depression rate of the women was 79.9%.The total score of SSRS of the women was 40.02±7.77 points.The rate of the total score of SSRS <20 points was 31.8%.The SAS and SDS scores of the women with RSA were negatively correlated with their SSRS score and their total SSRS score (P＜0.05).Multivariate analysis showed that age (36-40 years old, >40 years old), marriage duration >5 years, monthly family income (5001-10000 Yuan, 10001-30000 Yuan, >30000 Yuan) were the risk factors of anxiety of the women with RSA.Educational level (college, bachelor or above), monthly family income (5001-10000 Yuan, 10001-30000 Yuan, >30000 Yuan), childbearing history, and SSRS score were all the protective factors of anxiety of the women with RSA (all P＜0.05).Age (36-40 years old, >40 years old) and married years (>5 years) were the risk factors of depression of the women with RSA, while childbearing history and SSRS score were the protective factors of depression of the women with RSA (all P＜0.05).Conclusion: The women with RSA have obvious negative emotions of anxiety and depression, and the level of social support for them needs to be improved.The negative emotion of the women with RSA is mainly affected by age, birth history, and social support level.
