Abstract:
Objective To explore the impact of insomnia status in university students on cognitive flexi-bility.Methods The cluster sampling method was adopted.A total of 802 undergraduates in a university of Chongqing conducted the questionnaire survey by cognitive flexibility inventory(CFI)and Pittsburgh sleep quality index(PSQI).A total of 770 effective questionnaires were recovered.Sixty-six university student vol-unteers were recruited as the study subjects.The subjects with the PSQI≥8 points and being in insomnia state after interview served as the insomnia group(n=28)and the subjects with the PSQI＜8 points and not being in insomnia state after interview served as the control group(n=38).The study subjects all participated in behavioral study(adopting the number-letter transition task assesses the cognitive flexibility of the subjects).The differences in the reaction time,accuracy rate and switching cost were compared between the two groups.Results The total scores of CFI and PSQI in the university students group were(70.43±12.85)points and(6.37±3.29)points,respectively.The detection rate of insomnia was 33.77％(260/770).The CFI score in in-somnia individual was significantly lower than that in the sleep normal individual,and the difference was sta-tistically significant[(68.15±11.65)points vs.(71.59±13.28)points,P＜0.05].The Spearman partial correlation analysis indicated that the cognitive flexibility was negatively correlated with the PSQI total score(r=-0.22),subjective sleep quality(r=-0.22),sleep latency(r=-0.12),sleep disorders(r=-0.16),hypnotic drug use(r=-0.14)and daytime dysfunction(r=-0.16).The average reaction time,reaction time for repeat trials,reaction time for switch trials and switching cost in the insomnia group were longer than those in the control group,the CFI score and switch trial accuracy rate were lower than those in the control group,and the differences were statistically significant(P＜0.05).Conclusion The cognitive flexibility of the university students with insomnia is lower than that of the university students with normal sleep.The insom-nia status should be intervened.
