青少年网络成瘾者认知功能与睡眠状况测定及其相关性分析

目的：探讨青少年网络成瘾（IAD）者认知功能和睡眠状况的改变,阐明IAD者认知与睡眠相关指标间的关系。方法：选取42例青少年IAD者（病例组）和40例非成瘾者（对照组）分别进行事件相关电位（ERP）和匹兹堡睡眠质量指数（PSQI）测评,ERP主要分析N1、P2、N2、P3波潜伏期(PL)及P3波幅(amp),PSQI主要分析睡眠质量(SQ)、入睡时间(SL)、睡眠时间(ST)、睡眠效率(SE)、睡眠障碍(SD)、催眠药物(SP)和日间功能障碍(DD)7个因子分及总分值,并将病例组ERP中P3PL、P3amp与
PSQI中的7个因子分及总分进行相关性分析。结果：与对照组比较,病例组ERP中的N2 和P3波PL延长(P<0.01),P3amp降低（P<0.01）;在PSQI测定的各因子得分中
,与对照组比较,病例组SQ、SL、ST、SE、SD、DD因子分和总分差异均有统计学意义（P<0.01）。相关分析显示,病例组P3PL与PSQI测定中SQ、SL、ST、SE、SD、DD因子分和总分呈正相关关系（r分别为0.46、0.43、0.51、0.40、0.48和0.54,P<0.01）,而P3amp与以上各因子分和总分呈负相关关系（r分别为－0.42、－0.45、－0.49、－0.38、－0.38和－0.50,P<0.01）。结论：青少年IAD者存在一定程度的认知功能异常和睡眠障碍,且认知功能异常与睡眠障碍相互影响。

Determination of cognition function and sleep status in goungsters with internet addiction disorder and correlation analysis

Objective To explore the changes of cognition and sleep status in the youngsters with internet addiction disorder(IAD),and to clarify the relation between cognition and sleep-related indicators of IAD youngsters.Methods Event related potential(ERP)and Pittsburgh Sleep Quality Index(PSQI)test were used for forty-two IAD(case group)and forty non-IAD(control group)in youngsters,and the indexes of period latency(PL)of N1,P2,N2,P3and amplitude of P3(P3amp)of ERP were analyzed,the factor scores of sleep quality(SQ),sleep latency(SL),sleep time(ST),sleep efficiency(SE),sleep dysfunction(SD),sleeping pills(SP),daytime dysfunction(DD)and total score of PSQI were analyzed.The correlation between the P3PL,P3amp of ERP and all the indexes of PSQI in case group was analyzed.Results The PL of N2,P3of ERP in case group was significanly longer and the P3amp was significantly lower than those in control group(P<0.01);the factor scores of the SQ,SL,ST,SE,SD,DD,and the total score of PSQI test had significant differences between two groups(P<0.01).The correlation analysis results showed that there were remarkable positive correlations between the P3PL and the factor seores of the SQ,SL,ST,SE,SD,DD and the total score of PSQI test in case group(r=0.46,0.34,0.51,0.40,0.48,and 0.54;P<0.01),and there were remarkable negative correlations betweeb P3amp and the indexes of PSQI test in case group(r=-0.42,-0.45,-0.49,-0.38,-0.38,and-0.50;P<0.01).Conclusion The IAD youngsters have cognition and sleep dysfunction,and the both factors can affect each other.
