友谊嫉妒问卷在中小学生中应用的效度和信度

Validity and reliability of the Friendship Jealousy Questionnaire in primary and middle school students

目的:在我国中小学学生中对友谊嫉妒问卷(FJQ)进行修订并考察其效度和信度。方法:选取中小学学生500人(样本1)施测FJQ,用于条目分析和探索性因子分析;另外选取中小学学生476人(样本2)施测FJQ,用于结构效度及内部一致性信度检验;从样本2中选取60人施测嫉妒量表(BSJS)的社会嫉妒维度、生活满意度量表(SWLS)检验效标效度。1个月后,随机选取样本1中的100人进行重测,检验重测信度。结果:经条目分析和探索性因子分析,删除5个条目,保留10个条目,10个条目的因子载荷均>0.65,因子累积解释问卷总变异量的50.81%;验证性因子分析结果表明模型拟合较好(χ2/df=2.57,CFI=0.95,TLI=0.94,IFI=0.97,RM SEA=0.06,SRM R=0.04);FJQ总分与BSJS社会嫉妒维度总分及2个因子得分呈正相关(r=0.48、0.47、0.40,均P<0.01),与SWLS得分呈负相关(r=-0.21,P<0.01)。问卷的内部一致性信度Cronbachα系数为0.88,组合信度为0.89,重测信度为0.88。结论:修订后的友谊嫉妒问卷具有良好的效度和信度,可以作为测量和评估我国中小学生友谊嫉妒的工具。

Objective： To revise the Friendship Jealousy Questionnaire （FJQ） in primary and middle school students and assess its validity and reliability. Methods： Totally 500 students were recruited to complete the test version for item and exploratory factor analysis in sample 1. Totally 475 students in sample 2 were tested with formal version for further confirmatory factor analysis, internal consistency reliability and composite reliability. Sixty of sample 2 were selected randomly and asked to complete the dimension of social jealousy from Bringle Self-report Jealousy Scale （BSJS） and Satisfaction with Life Scale （SWLS）. One hundred students from sample 1 were ran- domly chosen and retested for test-retest reliability with one month interval. Results： Five items were deleted by i- tem analysis and exploratory factor analysis, finally 10 items were included. The factor loading of 10 items were o- ver 0.65. The accumulating explanatory rate of the 10 items was 50. 81%. Confirmatory factor analysis showed that FJQ had a good construct validity （x2/df= 2. 57, CFI = 0. 95, TLI = 0. 94, IFI = 0. 97, RMSEA = 0. 06, SRMR = 0. 04）. The FJQ scores were positively correlated with the dimension of social jealousy scores and two factors （r = 0. 48, 0. 47, 0. 40, Ps 〈0. 01）, and the FJQ scores were negatively correlation with the SWLS scores （r = -0. 21, P〈 0. 01）. The Cronbach a coefficient of the FJQ was 0. 88, the composite reliability was 0. 89, the test-retest reliability was 0. 88. Conclusion： The Friendship Jealousy Questionnaire is a reliable tool to assess the friendship jealousy for Primary and secondary students in China.
