个体相对剥夺感问卷在大学生群体的信效度检验

Reliability-validity Test of Personal Relative Deprivation Scale in Chinese College Students

翻译与修订个体相对剥夺感问卷(Personal Relative Deprivation Scale,PRDS),并在大学生群体中进行了信效度检验。探索性因子分析结果显示,原问卷中两个反向计分的项目在主因子载荷很低,删除这两个项目后的PRDS-3各项目鉴别力良好;探索性因子分析和验证性因子分析均显示PRDS-3符合单维度结构;PRDS-3重测信度为0.89,在不同样本间的内部一致性系数为0.77-0.81;PRDS-3得分与相对剥夺感、经济相对剥夺感、焦虑、压力、抑郁、攻击性等效标具有中高程度的相关关系(r>0.4,p<0.01)。PRDS-3得分与社会比较倾向的能力维度显著相关(r=0.46,p<0.01),且能部分地中介能力社会比较倾向对物质主义和生活满意度的影响。综上,可以认为,中文版PRDS-3信效度指标良好,符合测量学要求,可作为相对剥夺感的评估工具。

In the current study,the Personal Relative Deprivation Scale(PRDS)was translated and tested in terms of reliability and validity on Chinese college students.Exploratory Factor Analyses revealed that the two reverse-worded items from the original PRDS did not load onto the primary factor for the Chinese-translated PRDS.A reduced 3-item Chinese PRDS,however,showed good convergent validity.All items of the Chinese PRDS-3 showed high discriminability.The PRDS-3 accorded with the one-dimensional structure in both the exploratory and confirmatory factor analyses.The internal consistency coefficients of PRDS-3 ranged from 0.77 to 0.81 in different samples,and the retest reliability was 0.89,proving excellent reliability.The PRDS-3 scores were modestly-to-highly correlated with criteria such as the general relative deprivation,economic relative deprivation,anxiety,pressure,depression,and aggressiveness(r>0.4,p<0.01).The PRDS-3 score significantly correlated with social comparison tendency of abilities(r=0.46,p<0.01),and significantly mediated the effects of social comparison to materialism as well as life satisfaction.It can be concluded that PRDS-3 has high reliability and validity,meeting the requirements for psychometric tools.PRDS-3 can be used as an assessment tool of relative deprivation in China.
