Abstract:
Objective To explore the attention bias characteristics and impacts of attention training on negative attention bias of undergraduates with sub-clinical depression.Methods The undergraduates whose BDI scores being at the top of 5％ were recruited as participations and assigned to early attention training group and late attention training group using random number table.The dot probe paradigm was used to compare the difference of depressive symptoms and ingredients of attention bias made by different processing phases of attention training.Results (1)The BDI score after the training(87.91± 12.47) was significantly lower than that the former test (97.23±17.72) (F~,32)=4.78,P＜0.05),and the attention bias score in late attention training group (-5.97±2.92) was lower than that in the early attention training group(2.77±2.75) (P＜0.05).The interaction of the stimulus materials presenting time and the measuring time was significant(F(2,64) =4.76,P＜0.05).Simple effect analysis showed that when the time of stimulus material presenting was 1 000 ms,the score of negative attention bias after the test (-4.89 ± 23.66) was significantly lower than pre-test (7.73±26.14) (F(1,33) =5.11,P＜ 0.05).In the pre-test,the negative attention bias scores of the stimulus materials presenting time for 100 ms and 1 000 ms (8.62 ± 27.60,7.73 ± 26.14) were significantly higher than that for 500 ms (-12.80±29.09)(P＜0.05).(2)When the negative disengaged score as a dependent variable,the repetitive measure analysis of variance showed that the interaction effect of the stimulus materials' presenting time and training group type was significant (F(1,32) =4.41,P＜0.05).Simple effect analysis results indicated the negative disengaged score of the late attention training group at post-test (-5.84±7.79) was significantly lower than that at pre-test (24.16±7.35) (P＜0.05).Conclusion The attention training during the late stage of the attention process can efficiently intervene the negative attention bias of undergraduates with sub-clinical depression.
