目的探讨觉察压力量表(perceived stress scale,PSS)在新疆维稳民兵群体中的应用情况。方法采用分层抽样方法,选取新疆维稳民兵832名,进行数据的探索性因素分析和验证性因素分析。结果正式问卷包含13个条目,三个因子(预测感、控制感,超载感),解释了总变异的51.532%。量表Cronbach′sα系数为0.775,折半信度为0.703。量表与自我效能感、领悟性社会支持呈正相关,相关系数在0.148~0.343(P<0.01)间。验证性因素显示一阶三因素模型拟合效果比较理想。维稳民兵觉察压力因文化、年龄、来源、兴趣爱好而异。结论觉察压力量表具有较好的信效度,可用于维稳民兵群体觉察压力的测量;维稳民兵觉察压力呈现出文化、年龄、地域来源、兴趣爱好的特征。
Objective To explore the application of perceived stress scale (PSS) in the maintenance of militia groups in Xinjiang. Methods The stratified sampling method was used to select 832 peacekeeping militiamen in Xinjiang for exploratory factor analysis and confirmatory factor analysis. Results The formal questionnaire consisted of 13 items, three factors (Predictive, Control, Overload), explaining 51.532% of the total variance. The Cronbach’s α coefficient was 0.775 and the half-confidence was 0.703. The scale was positively correlated with self-efficacy and perceived social support, with correlation coefficients ranging from 0.148 to 0.343 (P <0.01). Confirmatory factors show that the first-order three-factor model fitting effect is ideal. Maintenance of stable militia perceived pressure due to culture, age, source, hobbies and differences. Conclusion The perceived stress scale has a good reliability and validity, which can be used to measure the perceived pressure of the militia groups. The stability of the militia maintains the characteristics of culture, age, geographical origin and hobbies.
