国际情绪图片系统在116名中国老年人中的试用

Native Assessment of International Affective Picture System among 116 Chinese Aged

目的:对美国NIMH情绪与注意研究中心编制的国际情绪图片系统在中国老年人群中进行试用,将结果与NIMH常模进行比较,探讨其异同。方法:在大连市三个社区的老年活动中心选取老年人116名(男:51人,女:65人),年龄60-80岁之间,对从国际情绪图片系统中选取的60幅图片(负性:23幅,中性:12幅,正性:25幅)进行愉悦度、唤醒度、优势度的9点量表评分,结果与NIMH常模进行比较。结果:中国老年人三个维度的评分与NIMH常模的相关系数分别为:0.92,0.54,0.88(P均<0.001)。中国老年人群的唤醒度和优势度评分高于NIMH常模[(5.33±0.93)v.s(4.83±1.25),(5.60±1.20)vs.(5.19±1.21),P<0.001],而愉悦度评分低于NIMH常模[(4.99±2.28)v.s(5.28±1.85),P=0.020]。男女老年人群对大多数图片的情绪感受相近,但女性老年人愉悦度评分高于男性老年人[(5.05±2.33)v.s(4.93±2.24),P=0.002]。在愉悦度-唤醒度二维情感空间中,60幅图片呈"<"形分布。正性图片愉悦度和唤醒度呈线性相关(r=0.71,P<0.001),负性图片两者的相关性不显著(r=-0.35,P>0.05)。结论:国际情绪图片系统具有较好的国际通用性。但由于中国老年人与NIMH常模在文化、生活、年龄等方面存在差异,故对部分图片的情绪感受不同,提示国际情绪图片系统应用于中国老年人群之前有必要进行本土化的修订。

Objective： To carry out the native assessment of International Affective Picture System （IAPS） among Chinese older adults. Methods： Altogether 116 Chinese older adults, including 51 male and 65 female, from three communities in Dalian City, aged from 60 to 80 years, rated 60 pictures （ positive： 25, neutral： 12, negative： 23 ） selected from the IAPS in terms of valence, arousal and dominance with Self-Assessment Manikin （ SAM ） . The mean affective ratings were compared to the normative ratings of USA National Institute of Mental Health （ NIMH） .Result： Reliability analysis indicated that the affective ratings of our sample were stable and highly internally consistent. The affective ratings of Chinese older participants were strongly correlated with the normative ratings of NIMH （ r = 0. 92, 0.54 and 0. 88 respectively for valence, arousal and dominance, P 〈 0. 001 ）. But paired t test showed there were still significant differences between the two samples. Chinese aged reported relatively higher arousal and dominance than NIMH sample for all pictures [ （5.33±0.93） vs. （4.83±1.25}, （5.60±1.20） vs. （5.19± 1.21）, P〈0. 001], but lower valence thanNIMH sample [ （4.99±2.28） vs. （5.28±1.85）, P=0.020] . Male and female Chinese older participants showed similar emotional responses to most pictures. But female Chinese older participants reported higher valence than male ones （ 5.05 ± 2. 33/4.93 ± 2. 24, P 〈 0. 05 } . The 60 pictures were distributed as ＂ 〈 ＂ shape in the two-dimensional affective space （ valence-arousal ） . The association between valence and arousal was pronounced and linear for positive pictures （ r =0. 71, P 〈0. 001 ）, but unpronounced for negative pictures, （ r = - 0. 35, P 〉 0. 05 ） . Conclusion： IAPS is highly internationally accessible just as the expectation of its designers. However, considering about great differences in many aspects such as culture, social living and age between Chinese aged and NIMH sample, they may have different affective experiences to the same emotional stimuli. Therefore it is necessary to do some revisal before the IAPS is applied to Chinese aged.
