A STUDY OF QUALITY OF SLEEP IN PEOPLE WITH MENTAL ILLNESS WITH SIGNIFICANT CLINICAL IMPROVEMENT

BACKGROUND Sleep disturbances have become a common co-morbid condition in psychiatric illnesses. Even after treating the immediate psychiatric symptoms, some individuals have difficulties in sleep and their quality of sleep is altered which further affects functional disability and quality of life of the patient. Aims and Objectives-To study the quality of sleep in people with mental illness with significant clinical improvement. MATERIALS AND METHODS Clinical Global Impression-Global Improvement (CGI-I) Scale and Pittsburgh Sleep Quality Index (PSQI) scale were used for the study. Patients attending review outpatient department of Tertiary Care Hospital, Hyderabad were selected as subjects, many of them being psychotic spectrum, mood disorder and alcohol-dependent patients. Patients who scored <4 on CGI-I scale were taken as subjects and PSQI was calculated. Out of 109 population size, 86 subjects meeting CGI-I score <4 were taken and PSQI for each subject was calculated. PSQI total </= 5 indicates good sleep quality. PSQI total >/= 5 indicates poor sleep quality. SPSS Software version 22 was used. Statistical analysis using Chi-square test, ANOVA was done, and Pearson co-relation test was done to find relation between sleep quality and medicine-induced sleep. RESULTS PSQI total was </= 5 in 33 patients. PSQI total was >5 in 53 patients. PSQI mean was calculated to be 7.65. Pearson Co-relation Coefficient (PCC) for sleep quality and medicine-induced sleep was found to be 0.179. Age is negatively co-related to medicine-induced sleep and positively co-related to CGI-I score. CONCLUSION Out of 109 patients, 86 patients scored <4 on CGI-I scale, 33 patients were having good sleep quality and 53 patients were having poor sleep quality. PCC of 0.179 indicates positive co-relation between sleep quality and medicine-induced sleep. Further research is needed to study co-morbid sleep disturbances in psychiatric illnesses.
