意外创伤患者认知评价和加工与社会支持对创伤后成长影响的路径分析

Path analysis on the influence of cognitive evaluation and processing and social support on post-traumatic growth in the accidental trauma patients

目的探讨意外创伤患者认知评价和认知加工与社会支持对创伤后成长的影响,并分析其影响路径。方法采用认知评价量表、事件相关反刍性沉思量表、社会支持量表及中文版创伤后成长问卷对336例意外创伤患者进行横断面调查。结果意外创伤患者创伤后成长(PTG)总分(58.74±13.53)分;目的性反刍总分、反刍性沉思总分与创伤后成长总分及各维度均呈正相关(r=0.578、0.439,P<0.01);侵入性反刍总分与创伤后成长总分呈负相关(r=-0.144,P<0.01);社会支持与创伤后成长总分呈正相关(r=0.492,P<0.01)。积极认知评价与目的性反刍性沉思在社会支持与创伤后成长之间起部分中介作用,中介效应为0.142,占总效应的13%。结论社会支持不仅可直接正向预测创伤后成长,还可通过积极认知评价和目的性反刍性沉思的中介作用间接预测创伤后成长。

Objective To explore the impact of cognitive evaluation,processing and social support on post-traumatic growth of patients with accidental trauma,and analyzed their impact path.Methods Cognitive evaluation scale,event-related rumination meditation scale,social support scale and Chinese version of post-traumatic growth questionnaire were used to conduct a cross-sectional survey on 336 patients with accidental trauma.Results The total score of post-traumatic growth(PTG)of patients with accidental trauma(58.74±13.53)and the total score of purposeful rumination and total rumination were positively correlated with the total score of post-traumatic growth and all dimensions(r=0.578,0.439,P<0.01);the total score of invasive rumination was negatively correlated with the total post-traumatic growth score(r=-0.144,P<0.01);the social support was positively correlated with the total post-traumatic growth score(r=0.492,P<0.01).Positive cognitive evaluation and purposeful rumination meditation played a partial mediating role between social support and post-traumatic growth.The mediating effect was 0.142,accounting for 13%of the total effect.Conclusion Social support not only directly predicted the post-traumatic growth,but also indirectly affected the post-traumatic growth through social support positive cognitive evaluation,and purposeful rumination.
