Prevalence of Insomnia and Relationship with Anxiety and Stress Among Rehabilitation House Officers: A Cross Sectional Study
Main Article Content
Abstract
Background: Insomnia is a prevalent sleep disorder associated with impaired daytime functioning and significant psychological morbidity, particularly among healthcare professionals exposed to high occupational stress. Evidence suggests a strong interrelationship between insomnia and psychological distress, including depression, anxiety, and stress, yet limited data exist for rehabilitation house officers in low- and middle-income settings. Objective: To determine the prevalence of insomnia and examine its association with depression, anxiety, and stress among rehabilitation house officers in Hyderabad. Methods: A cross-sectional study was conducted among 155 rehabilitation house officers recruited through convenience sampling from multiple institutions. Data were collected using a structured questionnaire, the Insomnia Severity Index (ISI), and the Depression Anxiety Stress Scale (DASS-21). Descriptive statistics were used to estimate prevalence, while associations were assessed using Spearman correlation and inferential statistical tests, with significance set at p<0.05. Results: Clinical insomnia (moderate–severe) was observed in 25.4% of participants, while 46.7% had subthreshold symptoms. Moderate-to-extremely severe depression, anxiety, and stress were reported in 43.9%, 49.7%, and 21.5% of participants, respectively. Insomnia severity showed significant positive correlations with depression (r=0.32, p<0.001), anxiety (r=0.26, p=0.002), and stress (r=0.28, p=0.001). Between-group analysis also demonstrated significant associations with depression (p=0.006), anxiety (p=0.034), and stress (p=0.028). Conclusion: Insomnia is highly prevalent among rehabilitation house officers and is significantly associated with psychological distress, particularly depression and anxiety, highlighting the need for early screening and targeted interventions to improve mental health and occupational performance.
