摘要
目的 通过分析眼动指标来探讨复发性抑郁缓解期个体对情绪面孔图片的注意偏向.方法 流调用抑郁自评量表(Center for epidemiologic studies depression scale,CES-D)筛选正常个体24人和抑郁情绪个体21人,汉密尔顿抑郁量表(Hamilton depression scale-17,HAMD-17)筛选复发性抑郁缓解期个体24人,通过分析被试的眼动指标来探讨复发性抑郁缓解期个体的注意偏向机制.结果 复发性抑郁缓解组对高兴面孔首视点持续时间偏向分数[(52.60±0.06)%]显著小于抑郁情绪组[(59.26±0.09)%]和正常组[(53.27±0.07)%],差异有统计学意义(F(1.66)=12.32,7.23,P<0.05).复发性抑郁缓解组对悲伤面孔的总注视时间偏向分数[(59.17±0.08)%]大于正常组[(49.67±0.07)%],差异有统计学意义(F(1.66)=4.29,P<0.05).结论 复发性抑郁缓解组被试对悲伤面孔和高兴面孔都没有表现出最初的定向偏向;复发性抑郁缓解组对悲伤面孔表现出最初的注意逃避和总体的注意维持.
Objective To explore the attentional bias to emotional faces on individuals in the remitted phase of recurrent depression through eye-tracking study.Methods Center for epidemiologic studies depression scale (CES-D) and Hamilton depression scale (HAMD) were used to the diagnosis of 24 normal individuals and 21 depressed individuals and 24 individuals in the remitted phase of recurrent depression.Emotion face pictures were chosen as experiment material and discuss the mechanism of the attentional bias of individuals in the remitted phase of recurrent depression through the analysis of eye movement index.Results First fixation duration bias score on happy expression picture of individuals in the remitted phase of recurrent depression((52.60±0.06) %) was less than normal controls ((59.26±0.09) %) and the depression group((53.27±0.07)%),(F(1.66)=12.32,7.23,P〈0.05).Gaze Duration Bias score on sad expression picture of individuals in the remitted phase of recurrent depression ((59.17±0.08) %) was more than normal controls((49.67±0.07) %),(F(1.66) =4.29,P〈0.05).Conclusion Individuals in the remitted phase of recurrent depression show no original direction bias to sad and happy expression pictures.Original attentional avoidance and total attentional maintenance to sad expression picture exist in individuals in the remitted phase of recurrent depression.
