Background: Sleep disturbance is one of the major problems schizophrenic
patients' faces that worsen their symptoms and lead to serious morbidities
and even increased mortality. We assessed the sleep quality and associated
factors among schizophrenic patients. Methods: We conducted a crosssectional
study using interviews of patients with questionnaires. Using the
Pittsburgh Sleep Quality Index (PSQI) and Morisky Green test (MGT), we
assessed sleep quality and antipsychotic medication adherence, respectively.
Results: We enrolled 377 participants who were mostly male (76.7%), Saudi
nationals (93.4%) and unemployed (79.3%), with a mean age of 36.38 ±10.59
years. The mean age of diagnosis of schizophrenia was 24.8± 8.30 years. Most
earned less than 3,000 Saudi riyals (SAR) per month (77.5%) and were using
two or more medications (92.3%). The majority (82%) of participants scored > 5
on the PSQI, indication poor quality of sleep (PSQI score > 5), while (18%) had
good quality of sleep (PSQI score < 5) and more respondents with a poor sleep
were significantly male (p=0.018), < 3000 SAR/ month earners (p = 0.006) and
unemployed (p=0.001). Only female gender was a significant independent
predictor for poor sleep quality (AOR=2.21, 95% CI: 1.00-4.88) (p=0.048) of all
Participants 72.3% were not adhering to their medications. Conclusion: We
found poor sleep quality among participants with poor adherence to
medications, indicating the necessity for measures to help them have good
sleep quality by addressing factors identified in order to ensure successful
care outcomes.
