甲基苯丙胺依赖青少年情绪面孔识别特征及影响因素

Characteristics and influencing factors of emotional face recognition on Methamphetamine dependence adolescents

目的探究甲基苯丙胺依赖青少年情绪面孔识别能力的特点及其影响因素。方法采用情绪面孔识别功能实验,对86名青少年甲基苯丙胺依赖者与85名健康志愿者进行施测。实验材料为自编一般信息调查问卷、情绪识别功能实验。结果(1)研究组男性和研究组女性情绪面孔识别能力与其年龄、文化程度、吸毒时间无显著相关(均P>0.05)。(2)研究组对于正性[(32.58±8.56)个]、中性[(32.76±8.06)个]、负性[(56.28±20.04)个]情绪面孔的判断正确数显著低于对照组对于正性[(35.64±3.91)个]、中性[(35.47±4.00)个]、负性[(71.02±8.62)个]情绪面孔的判断正确数(t=-3.00,-2.79,-6.24,均P<0.05);研究组对于正性[(401.32±175.13)ms]、负性[(502.08±194.42)ms]情绪面孔的判断反应时显著慢于对照组对于正性[(300.83±139.48)ms]、负性[(379.91±197.30)ms]情绪面孔的反应时(t=4.15,4.08,均P<0.05),研究组[(400.90±174.21)ms]与对照组[(356.67±156.70)ms]对于中性情绪面孔的判断反应时差异无统计学意义(t=1.75,P>0.05)。结论甲基苯丙胺依赖损害了青少年情绪面孔识别能力,其正性、负性情绪识别能力均存在加工缺陷。甲基苯丙胺依赖青少年情绪面孔识别能力不受年龄、文化程度和吸毒时间的影响。

Objective To explore the characteristics and influencing factors of methamphetamine dependence adolescents’emotional faces recognition ability.Methods Eighty-six adolescents methamphetamine addicts and 85 healthy volunteers were tested by a self-designed questionnaire and an experiment of emotional faces identification.Results(1)There was no significant correlation between the emotional faces recognition ability of the experimental group with their age,education level and drug time(P>0.05).(2)The correct number of positive(32.58±8.56),neutral(32.76±8.06),and negative(56.28±20.04)emotional faces recognition in the experimental group was significantly lower than that in the control group of positive(35.64±3.91),neutral(35.47±4.00),and negative(71.02±8.62)emotional faces recognition(t=-3.00,-2.79,-6.24,P<0.05).Meanwhile,the response time of positive((401.32±175.13)ms)and negative((502.08±194.42)ms)emotional faces recognition in the experimental group was significantly lower than that in the control group of positive((300.83±139.48)ms)and negative((379.91±197.30)ms)emotional faces(t=4.15,4.08,P<0.05).Nevertheless,there was no significant difference between the experimental group((400.90±174.21)ms)and the control group((356.67±156.70)ms)in the recognition response time of neutral emotional faces(t=1.75,P>0.05).Conclusion Methamphetamine dependence impairs the ability of adolescents’emotional faces recognition,and their positive and negative emotional recognition ability has processing defects.The ability of methamphetamine dependence adolescents to emotional faces recognition is not affected by their age,education level and time of drug uses.
