INTRODUCTION: The bipolar disorder is characterized by alternating and recurrent episodes of mania and hypomania with depression and periods of euthymia, with prevalence between 1 and 8% in the general population. The mental disorders influence the quality of life considerably, disturbing familiar, social and occupational relations. Sleep is also associated with the quality of life; moreover, it can be modified in bipolar disorder. OBJECTIVES: a) To verify if there is a difference between the perception of the quality of life and the quality of sleep in bipolar disorder when compared with a control-group; b) to verify the association between quality of life and quality of sleep in each group; c) to evaluate the intensity of depressive and anxiety symptoms and verify if these variables are different between the groups; d) to investigate possible association of depressive and anxiety symptoms in quality of life and quality of sleep; e) to verify if latency, duration and efficiency of sleep in the bad sleepers of the study-group are different from those of bad sleepers in the control-group. METHODS: The kind of research was case-control and the sample was characterized as a no-probability for convenience. Study-group (n=43) and control-group (n=80). The selection for the study-group had the following criteria of inclusion: patients with bipolar disorder in the stabilized phase who took part of the group of psychoeducation in a Psychiatric Hospital, age between 25 and 60, diagnostic of bipolar disorder, according to the criteria diagnostics of Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, in use of stabilizer of mood and absence of psychiatric comorbidity. The project has been approved by the Committee of Ethic of Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, da Universidade de São Paulo, Brazil. The instruments used in this process were: Pittsburgh Sleep Quality Index, Beck Depression Inventory, Beck Anxiety Inventory, World Health Organization Quality of Life Assessment, Clinical Interview Structuralized for the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, Modified Scale of Mania Evaluation and Brazilian Criteria of Economic Classification. RESULTS: a significant difference in the quality of sleep (p=0.045) has been found. The differences werent significant for the variables: quality of life (p=0.154), depressive symptoms (p=0.480) and anxiety symptoms (p=0.154). The variables quality of sleep and quality of life presented a significant correlation to both studygroup (p<0.001; r=0.534) and control-group (p<0.001: r=0.382). Significant differences in latency and duration of sleep in the subgroup of bad sleepers (p=0.026 and p=0.001, respectively) have been found. CONCLUSION: Patients with bipolar disorder presented perception of the quality of life, intensity of depressive and anxiety symptoms similar to those of subjects in the control-group not affected by this disorder. There has been a direct proportional association between the variables quality of sleep and quality of life. In the sub-group of bad sleepers in the study-group, the latency and duration of sleep had been increased compared to those in the sub-group of bad sleepers in the control-group.
