国际情绪图片系统在中国青年军人群体的初步应用

Primary assessment of international affective picture system in Chinese young soldiers

目的对国际情绪图片系统(international affective picture system,IAPS)在中国青年军人群体的应用进行初步评价。方法从国内修订的国际情绪图片系统选取300幅图片,对123名中国青年军人的愉悦度、唤醒度和优势度进行了自我报告的9点量表评分。结果评分稳定性、前后评分相关系数均在0.910以上(P<0.01),不同顺序组间各维度评分差异不明显(P>0.05)。②青年军人与一般人群三维度总体评分明显相关(P<0.01),相关系数依次为0.915、0.833、0.828,其唤醒度和优势度得分显著低于一般人群(P<0.01),愉悦度得分差别不明显(P>0.05)。③3种图片类型间各维度得分存在显著性差异(P<0.01),按正性→中性→负性的顺序,愉悦度和优势度均呈下降趋势,唤醒度呈"V"型变化趋势。结论IAPS在中国青年军人群体中评分稳定性较好,3个维度区分性较好,有较好的人群通用性。

Objective To evaluate the primary application of international affective picture system（IAPS）in Chinese young soldiers.Methods A total of 123 Chinese young health soldiers,at an age of 16 to 28（mean 20.97±2.86）,including 67 males and 56 males were recruited in this study.Totally 300 pictures,including 100 positive,neutral and negative pictures for each group,were exacted from Chinese modified IAPS,and 30 pictures from these 300 ones with 10 for each group were draw for the stability of the assessment.The rated valence,arousal and dominance of these soldiers were reported by themselves in a 9-point rating scale.Results The scores of pre and post rating were strongly correlated（P〈0.01）.The scores of valence,arousal and dominance did not predict markedly difference among the 3 rating sequences in dimension（P〉0.05）.The present study was strongly correlated with Chinese general sample ratings,and the Pearson coefficients were 0.915,0.833 and 0.828 respectively.Compared with Chinese general sample,the scores of arousal and dominance were decreased significantly in young soldiers.There were significant differences among positive,neutral and negative picture rating（P〈0.01）.In the sequence of positive,neutral and negative pictures,the scores presented a decline in valence and dominance,and a trend as ＂V＂ in arousal.Conclusion IAPS presents expected stability in rating,excellent differentiation in 3 dimensions and young soldiers＇ rating,and high population-accessibity in the sample of Chinese young soldiers.
