公共情绪量表在大学生人群中应用的信效度分析

Reliability and validity of public mood scale in college students

目的翻译编制公共情绪量表（中文版），并对其在大学生群体中的信效度进行检验。方法使用公共情绪量表对423名大学生进行测查，采用相关分析、探索性因素分析和验证性因素分析对量表进行信效度检验。结果探索性因素分析发现公共情绪量表分为积极情绪和消极情绪两个维度，两维度解释总方差的61．3％，各维度的项目载荷在0．68—0．86之间；积极公共情绪的Cronbach’α系数为0．81，消极公共情绪的克伦巴赫系（Cronbach’α系数）为0．76；验证性因素分析发现其结构效度非常理想，x2／df=1．538，GFI=0．947，AGFI=0．900，PGFI=0．500，RMR=0．048，RMSEA=0．067，联合因素分析的结果显示公共情绪和个人情绪是相分离的，x2／df=1．815，CFI=0．900，PNFI=0．597，RMSEA=0．057；积极公共情绪与大五人格的外向性、宜人性、责任心和开放性四维度都存在显著正相关（r=0．22-0．33，P〈0．01），与神经质维度存在显著负相关（r=-0．25，P〈O．01）；积极公共情绪与政府满意度、经济发展信心和社会稳定信心存在显著正相关（r=0．34-0．45，P〈0．01），消极公共情绪与它们则存在显著负相关（r=-0．32—-0．24，P〈0．01）。结论两维度公共睛绪量表具有良好的信度和效度，符合心理测量学的要求，可以作为评价公共隋绪可靠有效的量化工具。

Objective To develop the public mood scale and test its reliability and validity, and explore the components construct of the public mood. Methods 423 college students responded to the inventory. Correla- tion analysis, exploratory factor analysis and confirmatory factor analysis were applied to the data analysis. Results Public mood scale was consisted of two dimensions, positive emotions and negative emotions. Factor analysis indica- ted that the two factors explain 61.3% of the variance with factor loading ranging from 0.68 to 0.86;The Cronbach＇ s coefficients of positive and negative public mood were 0.81 and 0.76 respectively; Confirmatory factor analysis in- dicated that the public mood scale had ideal structure validity.Joint factor analysis showed that public mood and personal mood were separated.Positive public mood had positive correlations with Big Five personalities, which were extraversion, agreeableness, responsibility and openness （ r= 0. 22-0.33, P〈 0. 01 ）, negative correlation was found between neuroticism and positive public mood（ r=-0.25, P〈0.01）. Positive public mood had significant positive correlation with government satisfaction,economic development confidence and social stability（ r=0.34-0.45, P〈 0.01 ） ,while they had significant negative correlations with negative public mood （ r =- 0.32--0.24, P〈 0.01 ）. Conclusion The public mood scale obtained in the present study has ideal validities and reliabilities and it is suitable to assess the public mood.
