abstract="OBJECTIVE:To compare the differences of emotional conflict and cognitive fusion between depression patients with high and low suicidal ideation.<br><br>METHODS:Beck scale for suicide ideation-Chinese version(BSI-CV), Hamilton depression scale-17(HAMD-17), Beck depression inventory (BDI) and cognitive fusion questionnaire (CFQ) were used for evaluation.The 2&times;2&times;2 word-face Stroop task hybrid experimental design was used to compare the response time and accuracy of emotional face judgment in patients with depression with high suicidal ideation( n=22) and patients with depression with low suicidal ideation( n=22) using two-factor repeated measure ANOVA.BSI-CV scores of the two groups( n=44) were used as the dependent variable, and the reaction time of happy face, angry face, consistent face, inconsistent face, BDI score and CFQ score were used as independent variables to perform multiple linear stepwise regression analysis. <br><br>RESULTS:Both high and low suicidal ideation depression patients had emotional conflict effect in the word-face Stroop task, that was, compared with the face word inconsistent condition, the participants in the face word consistent condition had shorter response time ((707.19&plusmn;128.79)ms vs (793.55&plusmn;148.33)ms, F(1, 41)=11.38, P&lt;0.01, &eta;p2 =0.217)and higher accuracy(95.85&plusmn;4.50)%, (84.77&plusmn;11.54)%, ( F(1, 41) =6.06, P&lt;0.05, &eta;p2 =0.129). Under the condition of consistent face words, the response time of depression patients with high suicidal ideation was longer than that of depression patients with low suicidal ideation((803.69&plusmn;91.35) ms, (610.69&plusmn;78.13)ms, P&lt;0.01). The main effect of facial expression type was not statistically significant between the two groups, that was, depression patients with high and low suicidal ideation did not show attentional bias to happy faces or angry faces( F(1, 41) =0.68, P=0.413, &eta;p2 =0.016). Regression analysis results showed depression score, cognitive fusion score, and reaction time of inconsistent face had positively predictive effects on BSI-CV score( &beta;=0.40, 0.29, 0.29, all P&lt;0.05). <br><br>CONCLUSION:The cognitive fusion degree of the depression patients with high suicidal ideation is different from that of the depression patients with low suicidal ideation, but there is no difference in the emotion recognition. Reaction time of inconsistent face, cognitive fusion score and depression score have positively predictive effects on suicidal ideation.<p /><p>Language: zh</p>",
