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,P0.001).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),P0.001],but lower valence than NIMH 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,P0.05).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,P0.001),but unpronounced for negative pictures,(r=-0.35,P0.05).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.
