Abstract


ObjectiveDepressive cognitive theory assumes that the negative attentional bias may be a causal role in the maintenance of the occurrence and symptoms of depression, this study intended to directly change the depressive symptoms in individuals negative attentional bias to observe this negative attention through attention to experimental methods of bias correction trainingtend to correct the impact of depressive symptoms, in order to verify the core assumptions of the cognitive theory of depression, at the same time to explore this attention to the effects of bias correction training in treatment of depressive symptoms.MethodDouble-blind randomized controlled clinical experimental research methods. The second edition of the Chinese version of the Beck Depression Inventory (BDI-II) score≥14with mild to moderate to severe depressive symptoms (BDI-II range:) college students (N=77) were randomly divided into blank control group (only assess) in the placebo group training and attention bias training group, in which attention is to bias the training group and the placebo training group completed within2weeks8Attentional Bias training. All the previous test, measured after2weeks,4weeks,8weeks,3month follow-up completion of the above symptoms assessed. Results:In the training of Attentional Bias pretest attention bias in the assessment:①blank training group (27.54±17.13), the placebo group (24.87±17.22) and the training group (32.96±21.72) direct attention bias scores did not significantlydifference (F=1.281, P=0.284);②In the post-test attentional bias assessment training group, attentional bias scores occurred significantly changed (-21.26±24.31, t (26)=8.634, p <0.05),The other two groups but almost no significant change (blank control group,24.51±20.65, t (23)=0.69, p=0.493, placebo group,19.88±20.61, t (26)=1.088, p=0.287).2, in the training of Attentional Bias:1pretest assessment, the control group the BDI-II (18.13±5.18), the placebo group, BDI-II (18.04±4.12), BDI-II, the training group (17.33±3.81) BDI-II group (F=0.259, p=0.772) scores, no significant differences (>0.05).①but were in the training and track training group, the report depression scores decreased significantly p<0.01,2weeks tracking p<0.01,4weeks tracking p<0.01,8weeks tracking p-<0.01, three months to track the p-<0.01), while the depression level of the other two groups did not change, and the training group and the control group, the level of depression reported by the placebo group were significantly different (p <0.01post-test;2weeks p<0.01;4weeks p<0.01; weeks p<0.01, three months p<0.05).Conclusion:The results of this study indicate that①negative attentional bias may play a causal role in the maintenance of depressive symptoms; the②attention to bias correct the training is a long-term effective treatment methods to improve the symptoms of depression.
