Abstract: This study investigated the relationships between bedtime procrastination, rumination, and sleep quality among physically inactive students. Using a cross-sectional online survey design, a total of 135 physically inactive undergraduate students participated in the study. The participants were recruited through purposive sampling. It was hypothesized that both bedtime procrastination and rumination were associated with sleep quality. The study used the Bedtime Procrastination Scale (BPS), Ruminative Response Scale (RRS), and Pittsburgh Sleep Quality Index (PSQI) to assess bedtime procrastination, ruminative thought, and sleep quality, respectively. Data analysis was conducted using Pearson correlation coefficient. The results found a significant positive correlation between bedtime procrastination and sleep quality, r(135) = .758, p < .001. Similarly, a significant positive correlation was found between rumination and sleep quality, r(135) = .614, p < .001. In conclusion, the findings highlight that physically inactive students with greater levels of bedtime procrastination and rumination exhibited poorer sleep quality.
