简式情感强度量表中文版的信效度检验

The Reliability and Validity of the Short Affect Intensity Scale-Chinese Version

目的:建立简式情感强度量表(Short Affect Intensity Scale,SAIS)的中文版,并检验其信、效度。方法:831名大学生完成了SAIS等量表,有63人完成120张情绪图片的愉悦度和唤醒度的评分,另有91人间隔1个月第二次完成了SAIS。结果:SAIS中文版的Cronbach’sα系数总量表为0.86,三因子分别为0.86、0.75和0.84;条目间平均相关系数总量表为0.30,三因子分别为0.43、0.32和0.46;间隔1个月的重测信度总量表为0.83,三因子分别为0.79,0.82,0.85;各因子间的相关系数在0.39～0.62之间;正性情感强度与正性图片愉悦度及唤醒度的得分均存显著正相关,负性情感强度与负性图片的愉悦度显著负相关,而与负性图片的唤醒度得分显著正相关。验证性因素分析的指标:GFI为0.93,ACFI为0.92,CFI为0.95;RMSEA为0.045;条目对因子负荷系数在0.39-0.84之间。结论:简式情感强度量表中文版具有良好的信、效度,适用于我国大学生的情感强度评估。

Objective： To develop a Chinese version of Short Affect Intensity Scale（SAIS） and examine its reliability and validity.Methods： A sample of 831 undergraduate students finished SAIS and other scales,91 of them finished the SAIS twice,and 63 of them gave scores to the valence and arousal of 120 affective pictures.Results： The Cronbach’s α coefficient of the SAIS was 0.86;the mean inter-item correlation coefficient was 0.30;the test-retest reliability coefficient was 0.83.The correlation coefficients among the three factors ranged from 0.39 to 0.62.The GFI（0.93）,ACFI（0.92）,CFI（0.95） and RMSEA（0.045） all met the criteria for adequacy of fit.Conclusion： The Chinese version of the SAIS is a reliable and valid measure for assessing affect intensity in Chinese undergraduate students.
