Abstract:
ObjectiveTo explore the beliefs and attitudes about sleep in patients with comorbid depressive disorder and insomnia， and to explore its influence on sleep quality. MethodsPatients with comorbid depressive disorder and insomnia （n=61） and patients with primary insomnia （n=62） who met criteria specified in the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） in Beijing Anding Hospital Affiliated to Capital Medical University were enrolled， meantime， another 64 healthy controls were recruited. All subjects were assessed using Dysfunctional Beliefs and Attitudes about Sleep （DBAS） and Pittsburgh Sleep Quality Index （PSQI）. Additionally， patients with comorbid depressive disorder and insomnia were evaluated using Hamilton Depression Scale-17 item （HAMD-17）. The PSQI and DBAS scores were compared among three groups using analysis of covariance， and multiple linear regression analysis was used to screen the factors affecting PSQI score in patients with comorbid depressive disorder and insomnia. ResultsCompared with healthy controls， higher scores of PSQI （t=18.932， 18.610， P<0.01） along with lower scores of DBAS （t=-5.561， -5.791， P<0.01） were observed in patients with comorbid depressive disorder and insomnia and patients with primary insomnia. Taking the PSQI score of patients with comorbid depressive disorder and insomnia as the dependent variable， statistically significant equations were generated using multiple linear regression analysis （F=14.095， R2=0.327， P<0.05）， and the predictive and control factors of sleep in DBAS and age were found to be the influencing factors of PSQI score in patients （B=-0.100， -0.279， P<0.05 or 0.01）. ConclusionCompared with the normal，depression patients with insomnia have more dysfunctional beliefs and attitudes towards sleep，and dysfunctional cognition may be the influencing factor of their sleep quality.
