链式中介效应模型分析武警某部新兵压力知觉对集训应激后成长的作用

Relationship between perceived stress and post-traumatic growth of training recruits among armed police:a chain mediating model

目的探讨新兵压力知觉影响集训应激后成长的作用方式,以更好地管理新兵的心理健康。方法采用新兵集训应激后成长量表、中文版压力知觉量表、基本心理需要满足-关系需要分量表和应对效能量表,对675名新兵进行测量,采用SPSS 26.0软件进行描述性统计、相关分析和中介效应检验。结果回收有效问卷623份,有效率为92.3%。新兵的压力知觉量表总均分为(34.31±8.47)分,关系需要量表总均分为(45.90±7.93)分,应对效能量表总均分为(57.37±7.32)分,应激后成长量表总均分为(81.70±20.56)分。关系需要和应对效能在压力知觉对应激后成长的影响中起部分中介作用,中介作用通过3条路径(P<0.05)产生效应:(1)由压力知觉、关系需要、应激后成长产生的路径1(效应值为-0.175,占总效应比例为33.59%);(2)由压力知觉、应对效能、应激后成长产生的路径2(效应值为-0.254,占总效应比例为48.75%);(3)由压力知觉、关系需要、应对效能、应激后成长产生的路径3(效应值为-0.049,占总效应比例为9.41%)。结论新兵压力知觉、关系需要、应对效能三者与集训应激后成长关系密切,关系需要和应对效能在新兵压力知觉和集训应激后成长中起到链式中介效应。应关注新兵的情绪状态,营造温暖和谐团队氛围,满足新兵的归属感,增强其行动的自信心和应对效能感,以促进新兵心理成长。

Objective To explore the effect of the needs for relatedness on post-traumatic growth coping efficacy of training recruits,in order to better manage the mental health of recruits.Methods A group of 675 training recruits were assessed by the post-traumatic growth Inventory for Recruits Training(PTGI-RT),Chinese version Perceived Stress Scale(CPSS),Basic Psychological Needs Satisfaction Relatedness Subscale and Coping Efficacy Questionnaire.SPSS26.0 was used for descriptive statistics,correlation analysis and mediation effect test.Results Totally 623 valid questionnaires were collected,and the effective response rate was 92.3%.The total average score of the recruits’stress perception scale was(34.31±8.47),the total average score of the relationship needs scale was(45.90±7.93),the total average score of the coping efficacy scale was(57.37±7.32),and the total average score of the post stress growth scale was(81.70±20.56).Relationship needs and coping efficacy played a partial mediating role in the impact of stress perception on post stress growth.The mediating role produces effects through three paths:(1)path 1 produced by stress perception,relationship needs and post stress growth(the effect value was-0.175,accounting for 33.59%of the total effect);(2)path 2 produced by stress perception,coping efficacy and post stress growth(the effect value was-0.254,accounting for 48.75%of the total effect);(3)path 3 produced by stress perception,relationship needs,coping efficacy and growth after stress(the effect value was-0.049,accounting for 9.41%of the total effect),which were statistically significan(t P<0.05).Conclusions Recruits’stress perception,relationship needs and coping efficacy were closely related to the growth after intensive training stress.Relationship needs and coping efficacy played a chain intermediary effect in recruits’stress perception and growth after intensive training stress.We should pay attention to the emotional state of recruits,create a warm and harmonious team atmosphere,meet the recruits’sense of belonging,enhance their self-confidence and coping efficacy,so as to promote the psychological growth of recruits.
