自我效能在Stanford A型主动脉夹层术后患者社会支持和心理韧性的中介作用

Mediating effect of self-efficacy between social support and resilience in type A aortic dissection patients

目的为明确Stanford A型主动脉夹层患者术后社会支持对其心理韧性的作用机制,本研究构建了一个中介模型,重点考察自我效能在二者关系中的中介作用。方法采用便利抽样法,使用自编一般人口学资料调查表、自我效能感量表、社会支持评定量表和心理韧性量表对广东省某三甲医院125例Stanford A型主动脉夹层术后患者进行问卷调查。结果Stanford A型主动脉夹层术后患者心理韧性为(63.78±12.29)分,自我效能总分为(27.22±5.16)分,社会支持得分为(43.77±6.82)分;自我效能感与社会支持、心理韧性均呈正相关(r=0.571,0.717,P<0.01),社会支持与心理韧性呈正相关(r=0.611,P<0.01);自我效能在社会支持和心理韧性间起部分中介作用,中介效应占总效应的比例为37.43%。结论社会支持可通过自我效能影响Stanford A型主动脉夹层患者术后的心理韧性,医务人员应积极采取有效干预方法提高患者的自我效能感,增加社会支持水平,从而提升其心理韧性水平。

Objective To construct a mediation model to clarify the mechanism of the effect of social support on resilience in patients after surgery for acute type A aortic dissection patients,and to explore the mediating effect of self-efficacy between social support and resilience.Methods We selected 125 type A aortic dissection patients in a tertiary grade-A hospital in Guangdong province and they were investigated by using the general information questionnaire,the Social Support Rating Scale,General Self Efficacy Scale,and Connor-Davidson Resilience Scale.Results The score of resilience and social support of patients was(63.78±12.29),and(43.77±6.82)respectively.The total score of self-efficacy was(27.22±5.16).There was a significantly positively correlation among social support,resilience,and self-efficacy(r=0.571,0.717,P<0.01).Social support positively associated with the resilience(r=0.611,P<0.01).Self-efficacy has some mediating effect between social support and resilience,which accounts for 37.43%of the total effect.Conclusion Social support exerts influence on the resilience of Type A aortic dissection patients through self-efficacy.Effective measures to improve patients′self-efficacy should be considered,thus to enhance their level of resilience.
