女性强制隔离戒毒人员毒品相关刺激注意偏向矫正训练研究

Attentional bias modification on drug-related stimulus of female drug abuse in a compulsory rehabilitation center

目的:调查注意偏向矫正训练能否改变女性戒毒人员对毒品相关刺激的注意偏向。方法:采用点探测任务选取对毒品刺激存在注意偏向的被试51人,随机分配到训练组(n=26)和安慰剂组(n=25),两组被试分别完成前测、训练和后测,训练阶段训练组完成4次点探测任务变式训练,安慰剂组完成4次点探测任务,每天训练1次。采用单样本t检验比较被试注意偏向得分与0的差异,以及两因素重复测量方差分析比较两组被试前后测注意偏向得分的差异。结果:安慰剂组在前测和后测中均对毒品相关刺激存在注意偏向,训练组在前测中对毒品相关刺激存在注意偏向,但经过注意偏向矫正训练后,注意偏向改变为注意回避。结论:注意偏向矫正能够降低女性戒毒者对毒品相关刺激的注意偏向。

Objective:To investigate whether the attentional bias modification training can change the attention bias to the drug-related stimuli of female drug abusers in a compulsory rehabilitation center.Methods:51 subjects with attention bias to drug stimulation were randomly assigned to training group(n=26)and placebo group(n=25).The subjects in the two groups completed pre-test,training and post-test,respectively.During the training phase,the training group completed the changed dot probe 4 times,while the placebo group completed the dot probe 4 times,and trainied once a day.We used single sample t test to compare the difference between the attention bias scores and 0,then used two-ways repetitive measurement and analysis of variance to compare the differences between pre-test and post-test of two groups′attention bias scores.Results:The placebo group showed an attentions bias towards the drug-related stimuli in both previous and post-test,and the training group showed an attention bias towards the drug-related stimuli in the previous test,but the attention bias towards changed to attention avoidance after the training.Conclusion:Attention bias modification training can reduce the attention bias of female drug abusers on drug-related stimuli.
