Psychological Strain and Daytime Dysfunction among Students in Kathmandu Valley: Controlling for Sleep Disturbance

Abstract

This study examined whether psychological strain predicts daytime dysfunction among Bachelor’s and Master’s students in Kathmandu Valley, controlling for sleep disturbance. Data were collected from 235 students using a structured questionnaire. Psychological Strain, measured using four items, demonstrated good reliability (α = .740), while Sleep Disturbance (10 items) and Daytime Dysfunction (8 items) showed high reliability (α = .835 and .843, respectively). Psychological Strain alone explained 54.6% of the variance in Daytime Dysfunction (R² = .546). After controlling for Sleep Disturbance, the model explained 58.4% of the variance (R² = .584), with Psychological Strain remaining a highly significant independent predictor. These findings indicate that psychological strain is strongly associated with daytime dysfunction among university students. Implications for students and academic institutions in Kathmandu Valley are discussed.
