OBJECTIVES: To compare subjective sleep quality and insomnia severity across patients with different psychiatric disorders using validated patient-reported outcome measures (PROMs).
METHODS: A total of 196 patients from the psychiatric unit were included in this cross-sectional study, conducted at the tertiary care hospital. Two PROMs, the Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI), were used to evaluate the patients, and the data were analyzed using IBM SPSS software version 30.
RESULTS: Findings revealed a high prevalence (68.37%) of insomnia and poor sleep quality among the psychiatric participants. The mean global PSQI and total ISI scores were highest for patients diagnosed with schizophrenia (PSQI: 14.10 ± 4.30, ISI: 15.90 ± 7.29), followed by those with depressive disorder (PSQI: 11.95 ± 4.70, ISI: 13.85 ± 6.84) and generalized anxiety disorder (PSQI: 11.07 ± 4.59, ISI: 12.93 ± 6.92). Correlation analysis showed a strong, positive correlation (r = 0.82, p < 0.01) between total ISI and global PSQI score, indicating that greater insomnia severity was significantly associated with poorer overall sleep quality.
CONCLUSIONS: This study highlights the high burden of insomnia and impaired sleep quality in individuals with schizophrenia, depressive disorder, and generalized anxiety disorder, specifically. The strong association between ISI and PSQI highlights the importance of routine screening and integrating management of sleep disturbances in psychiatric care settings, aiming to improve clinical outcomes and overall quality of life.
