ABSTRACT

Objective To explore the relationships between loneliness and sleep quality of undergraduates.Methods 751 undergraduates were investigated by UCLA Loneliness Scale and Pittsburgh Sleep Quality Index( PSQI).Results (1) No gender,grade and origin differences on loneliness were found,but non-only child undergraduates(43.09±7.22)felt lonely more than only-child undergraduates(41.37±8.38)(t=2.95,P=0.003).(2) No gender,grade and yes or no only child differences on the total score of PSQI were found,but undergraduates come from country (5.00±2.68)scored higher than those from city(4.59±2.79)(t＝2.019,P＜0.05).(3)Loneliness had significant positive correlations with the total score on the PSQI and the six components(except sleep duration)(r=0.12～0.27,P＜0.05～0.01).Lonely(5.72±3.25,1.20±0.93,1.09±0.70,0.23±0.64,1.64±0.93)and non-lonely undergraduates (4.63±2.56,0.99±0.79,0.96±0.53,0.08±0.37,1.39±0.85)differ significantly in total score of PSQI,sleep latency,sleep disturbance,sleep medication and daytime dysfunction(t=2.096～3.681,P＜0.05～0.001).Conclusion Loneliness of undergraduates maybe influence their sleep quality.
