目的 探讨心理行为干预在先兆流产患者中的应用效果。方法 选择2019年7月—2020年11月潮州市人民医院收治的先兆流产患者82例，按随机数字表法将患者分为对照组和干预组，每组各41例。对照组实施常规护理，干预组在常规护理的基础上予以心理行为干预。使用量表对比分析两组患者干预前后心理状态、心理压力、社会支持及保胎情况的差异。结果 干预前，两组患者焦虑自评量表(self-rating anxiety scale, SAS)、抑郁自评量表(self-rating depressive scale, SDS)、压力感知量表(pressure perception scale, PSS)、社会支持评定量表(social support rating scale, SSRS)评分相比，差异均无统计学意义(均P>0.05)。干预后，干预组SAS、SDS、PSS评分分别为(39.35±6.13)分、(40.38±6.69)分、(14.42±5.17)分，低于对照组的(48.64±6.32)分、(49.63±7.41)分、(19.58±5.43)分，差异有统计学意义(P<0.05);干预组的SSRS评分(47.95±10.33)分高于对照组的(31.07±8.87)分，差异均有统计学意义(均P<0.05)。干预组保胎成功率(92.68%)高于对照组(75.61%),差异有统计学意义(P<0.05)。结论 心理行为干预能够缓解先兆流产患者的负性情绪，降低其心理压力，提高患者社会支持，利于保胎成功。

Objective To explore the effect of psychological and behavioral intervention on patients with threatened abortion. Methods A total of 82 patients with threatened abortion who were admitted to Chaozhou People's Hospital from July 2019 to November 2020 were recruited. They were divided into two groups(routine care group and intervention group) according to the random number table method, with 41 cases in each group. Kinds of scales were used to compare and analyze the psychological state, psychological pressure, social support and fetal protection pre-and post-intervention between two groups. Results Scores of self-rating anxiety scale(SAS), self-rating depressive scale(SDS), pressure perception scale(PSS), and Social Support Rating Scale(SSRS) between 2 groups were not different significantly before intervention(all P>0.05). After intervention, scores of SAS、SDS、PSS of intervention group were lower than those of the control group,(39.35±6.13) vs.(48.64±6.32),(40.38±6.69) vs.(49.63±7.41), and(14.42±5.17) vs.(19.58±5.43) respectively. But SSRS score of intervention group was higher than that of the control group(47.95±10.33) vs.(31.07±8.87), the differences were statistically significant(all P<0.05). The rate of miscarriages preservation of the intervention group(92.68%) was higher than that of the control group(75.61%), and the difference was statistically significant(P<0.05). Conclusion Psychological and behavioral intervention can relieve the negative emotions of patients with threatened abortion, reduce their psychological pressure, and improve their social support, which is conducive to the success of miscarriage prevention.
