Research On The Intervention Of Positive Mental Imagery On Behavioral Activation Of Depressed Individuals

Objective: This study aims to conduct a half-month training for college students with depression through behavioral intervention,and to study the improvement of behavioral activation and depression symptoms of college students with depression after the completion of a half-month training task through the intervention mode of positive mental imagery for depressed individuals.Method: In the first study,40 volunteers were recruited to participate in the evaluation,and four groups of training materials for behavioral activation were evaluated,namely,positive behavior pictures,positive behavior words,neutral words and neutral pictures.The four groups of materials provided materials for the intervention in the second study.Research adopted two flow adjustable center depression rating scale(CES-D)and self-evaluation of the beck depression inventory(BDI)selected 80 college students have depression as experimental object,they were randomly assigned to study the evaluation of four kinds of training materials,the experiment using a pretest,posttest design,intervention materials for text,images,through the training for half a month to compare four kinds of materials of students in depression depressed mood,and behavior of the activated.The depression level(CES-D,BDI),behavioral activation level(BADS)and three eye movement data indicators(number of fixation points,total fixation time and duration before reaching interest area)of depressed college students were respectively compared to explore whether positive mental imagery is effective in intervening behavioral activation of depressed individuals.Result:(1)Compared with the neutral word training group,the positive behavior word training group had significantly higher behavioral activation level and significantly lower depression level after training.(2)Compared with the neutral picture training group,the behavioral activation level and depression level of the positive behavior picture training group were significantly increased after thetraining.(3)During the two-week follow-up,compared with the neutral word training group,the behavioral activation level in the positive behavior word training group was significantly higher than that before the training,and the depression level was significantly reduced.(4)During the two-week follow-up,compared with the neutral picture training group,the level of behavioral activation in the positive behavior picture training group was significantly higher than that before the training,and the level of depression was significantly reduced.(5)Compared with the neutral text training group,the number of fixation points and fixation time in the positive area increased after the training and the duration before reaching the interest area decreased in the positive behavior text training group.(6)Compared with the neutral image training group,the number of fixation points and fixation time in the positive behavior image training group increased after the training,while the duration before reaching the interest area decreased.Conclusion :(1)Positive mental image training can improve depressive mood of depressed individuals.(2)Positive mental image training can improve behavioral activation level of depressed individuals.(3)Depressed individuals tend to pay attention to positive stimuli,and positive mental image training can increase the attention of depressed individuals to positive stimuli.
