冠心病与抑郁症共患者情绪 Stroop 效应任务研究
The Emotional Stroop Effect in Coronary Heart Disease Combined With Depression Patients
摘要
Abstract
Objective To explore whether coronary heart disease( CHD)combined with depression patients have attention bias to negative information. Methods 44 CHD patients who were admitted to the Department of Cardiology,the Affiliated Hospital of Weifang Medical University from May 2013 to August 2014,were selected as study subJects. According to the score of Zung self - rating depression scale and the diagnosis of clinical psychiatrists,they were divided into the CHD with depression group and the simple CHD group. Patients completed the emotional Stroop task,and the amplitude and latency of the accuracy rate,reaction time and interference effect were recorded. Results Cases who underwent improper operation,and cases who had physical discomfort were excluded. There were 13 patients in the CHD with depression group and 27 patients in the simple CHD group. The repeated measures analysis of variance(RANOVA)on accuracy rate showed the main effect of threshold type was significant(F = 16. 08,P < 0. 001),the accuracy rate of the supraliminal type was higher than that of the subliminal type;and the main effect among groups was significant( F = 6. 48,P < 0. 001),with the accuracy rate in the CHD with depression group was lower than that in the simple CHD group. The RANOVA on reaction time showed the main effect among groups was significant(F = 21. 68,P < 0. 001),the reaction time in the CHD with depression group was longer than that in the simple CHD group;the main effect of word property was significant(F = 83. 61,P < 0. 001),the reaction time of negative words was longer than that of positive words and neutral words;there was a significant interaction effect between threshold type and group(F = 4. 34,P = 0. 004),and between group and word property( F = 4. 01,P = 0. 005). Simple effect analysis revealed that the reaction time of positive words and negative words in the CHD with depression group were longer than those in the simple CHD group respectively(F = 16. 14,P < 0. 001;F = 17. 11,P < 0. 001),the reaction time of negative words was longer and that of positive words and neutral words in the CHD and depression group(F = 10. 09,P < 0. 001). The RANOVA on the interference effect revealed that the main effect of word property was significant( F = 43. 61,P < 0. 001 ),the interference effect of negative words was greater than that of positive words;and group × word property × threshold type interaction was significant(F = 5. 73,P = 0. 001). Further analysis based on threshold type found that when the stimulus was presented by the supraliminal type,the main effect of word property was significant(F = 5. 97,P = 0. 001),the interaction effect between group and word property was significant(F = 6. 49,P < 0. 001). Simple effect analysis revealed that there was no significant difference in the interference effect of positive words between the two groups(F = 1. 08,P = 0. 07);but the interference effect of negative words in the CHD with depression group was greater than that in the simple CHD group(F = 6. 24,P < 0. 001);and the interference effect of negative words were greater than those of positive words in the CHD with depression group and the simple CHD group respectively(F = 4. 40,P = 0. 04;F = 5. 45,P = 0. 02). Conclusion CHD combined with depression patients have interference supression function obstacle to negative words presented on the threshold,so they do have a negative attention bias.关键词
