RESUMO
Objective@#To investigate the relationship between sleep beliefs and attitudes and sleep quality in patients with stable coronary heart disease.@*Methods@#Totally 390 patients with stable coronary heart disease were investigated by the Pittsburgh Sleep Quality Index (PSQI), Dysfunctional Beliefs and Attitudes about Sleep Scale-16(DBAS-16) and a general information questionnaire which was designed by researchers.@*Results@#48.2% of patients with stable coronary heart disease reported poor sleep quality at home, and the total score of PSQI was (7.99 ± 4.061), the total score of DBAS was (47.44 ± 9.77). Univariate anova showed that age (F=14.567, P<0.01), gender (H=16.657, P<0.01), marital status (F=4.706, P=0.031), job status (F=15.738, P<0.01) and the number of comorbid diseases (F=4.674, P=0.003),are factors affecting sleep quality. Pearson correlation analysis showed that there were significantly negative correlation between PSQI and DBAS (r=-0.260, P<0.01). Multiple Linear Regression showed that sleep beliefs and attitudes, gender, age, the number of comorbid diseases were influencing factors of sleep quality (R2=0.247, F=17.907, P<0.01).@*Conclusions@#The sleep quality at home in patients with stable coronary heart disease was closely related to sleep beliefs and attitudes. Nurses should pay more attention to the sleep quality of patients, correct their incorrect sleep cognition timely, and improve their sleep quality.
