The Intervention Of Attention Bias Modification Training On Cognitive Bias In Depression

Objective: Depression is a more complicated mental illness,which has become an urgent problem to be solved.The aim of our study is to explore whether depression patients have attention bias,and to evaluate whether attention bias modification training could interfere with cognitive biases in depression and explore whether attention bias modification training could improve the symptoms of depression.It provides a new method to the treatment and intervention of the depression,so as to further enrich the treatment of depression.Methods: 60 patients met the depressive disorders criteria of ICD-10 and rated scores of Hamilton Depression Scale(HAMD)(17 items)more than 17 scores were randomly divided into research group(30 cases)and control group 1(30 cases).At the same time,30 normal subjects were randomly selected as control group 2.Research group were given SSRIs treatment and attention bias modification training for three times a week,a total of four weeks,and control group 1 were only given SSRIs treatment.Control group 2 only completed assessments.Hamilton Depression Scale(HAMD),Metacognition questionnaire(MCQ),Automatic Thoughts questionnaire(ATQ),and Cognitive Bias questionnaire(CBQ)were used to assess the two groups before and after two weeks and four weeks treatment.Try to explore the impact of attention bias modification training to attention bias,depressive symptoms and cognitive biases in depression by comparing the changes of depressive symptoms and cognitive biases before and after treatment between the research group and control group.Results: 1.Before drugs and attention bias training,the attention bias scores,and the scores of HAMD rating scale,ATQ,MCQ,and each factor of CBQ were significantly different between depression patients and normal subjects(p <0.01).2.Before treatment,the attention bias scores,and the scores of HAMD rating scale,ATQ,MCQ,and each factor of CBQ were not difference between the research group and the control group 1(p >0.05).3.After four weeks treatment,there was no statistically difference between the HAMD rating scale scores of the research group and the control group 1(p >0.05).The attention bias scores of the research group were significantly lower than that in the control group 1(p <0.01).The scores of MCQ in the research group were significantly different lower than that in the control group 1(p <0.05).The scores of ATQ scale in the research group were no difference compared with that in the control group 1(p >0.05).In the CBQ scale,the factor scores of depressed-distorted and non-depressed-distorted were no difference between the research group and the control group 1(p >0.05),and the factor scores of depressed-non-distorted and non-depressed-non-distorted in the research group were significantly lower than that in the control group 1(p <0.05).4.After four weeks,the scores of attention bias in the research group were no difference compared with that in the normal control group 2(p >0.05).And the scores of HAMD scale,MCQ scale,as well as the ATQ scale were significantly different between that in the research group and that in the normal control group(p <0.01).In the CBQ scale,the factor scores of depressed-distorted,non-depressed-distorted,and depressed-non-distorted were no statistical difference(p >0.05),and the factor scores of non-depressed-non-distorted in the research group were significantly different compared with that in the normal group(p <0.01).Conclusion: 1.Depression patients have attention biases towards negative emotional stimuli.2.Attention bias modification training could effectively change the attention bias in depression.3.Attention bias modification training could effectively interfere with metacognition and cognitive biases in depression.
