内观疗法对网络成瘾患者内隐认知的影响

Effect of Naikan therapy on implicit cognition in individuals with Internet addiction disorder

目的应用反应/不反应内隐关联实验(GNAT)评价内观疗法对网络成瘾(IAD)个体内隐认知的影响。方法选择符合修订的《Young网络成瘾诊断问卷》IAD标准的30例患者作为IAD组,在本院职工及子女中选择与IAD组匹配性别、年龄的30例健康者作为对照组。IAD组给予内观治疗12周。GNAT的线索刺激(靶刺激)选自网络游戏《魔兽世界》中部分图片,共20张;态度词包括具有正性与负性含义(各20个)的词汇作为态度属性评定。共分2个实验。实验1:靶图片与正性态度词出现时迅速按键,靶图片与负性态度词出现时不按键;实验2:靶图片与负性态度词出现时迅速按键,靶图片与正性态度词出现时不按键。刺激反应时间1 000 ms,刺激间隔1 500 ms。比较Go刺激正确(Hit)率、反应时间(RTs)及No-go刺激的错误(False)率。结果实验1:治疗前IAD组RTs和False率明显低于对照组,Hit率明显高于对照组,差别具有统计学意义(P<0.05);IAD组治疗12周后RTs、Hit率以及False率与治疗前比较差别具有统计学意义(P<0.05)。实验2:治疗前IAD组RTs和False率明显高于对照组,Hit率明显低于对照组,差别具有统计学意义(P<0.05);IAD组治疗12周后RTs、Hit率以及False率与治疗前比较差别具有统计学意义(P<0.05)。治疗12周后IAD组与对照组在实验1与实验2中,2组RTs、Hit率以及False率比较差别均无统计学意义(P>0.05)。结论内观疗法能够改善IAD个体内隐认知,具有一定的治疗意义。

Objective To investigate the effect of Naikan therapy on implicit cognition in individuals with Internet addiction disorder（IAD）using Go/No-go association test（GNAT）.Methods Thirty individuals consistent with modified YDQ criteria were selected as IAD group and 30 healthy persons with matching sex and age with IAD group were selected as control group.IAD group were treated with Naikan therapy for 12 weeks.Target stimuli of GNAT were 20 pictures selected from a video game World of Warcraft.Expressions of attitude including 20 positive words and 20 negative words were used to evaluate attribute.There were two trials.Trial 1：When target cards and positive words occurred,press quickly,while target cards and negative words occurred,did not;Trial 2 was just opposite.The irritant reaction time was 1 000 ms and the stimulus intervals was 1 500 ms.Hit rate,react times（RTs） and false alarm（False） rate were compared.Results Trial 1：The RTs and False rate in IAD group were lower than those in control group before treatment,while Hit rate was higher（P0.05）.Compared with before treatment,there were stastiscally significant in RTs,Hit rate and False rate in IAD group after 12 weeks of treatment（P0.05）.Trial 2：The RTs and False rate in IAD group were higher than those in control group before treatment,while Hit rate was lower（P0.05）.Compared with before treatment,there were stastiscally significant in RTs,Hit rate and False rate in IAD group after 12 weeks of treatment（P0.05）.After 12 weeks of treatment,there were no stastiscally sigificant in the differences of RTs,Hit rate and False rate between IAD group and control group（P0.05）.Conclusion Naikan therapy can improve implicit cognition in individuals with IAD.
