Smartphone Addiction and Sleep Disturbances Among Medical Students: A Cross-Sectional Study.

Other sleep dimensions, including sleep latency (r = 0.19, p = 0.07), sleep disturbance (r = 0.204, p = 0.06), sleep duration (r = -0.08, p = 0.43), sleep medication use (r = 0.05, p = 0.59), and daytime dysfunction (r = 0.1, p = 0.2), did not reach statistical significance (p > 0.05), though the positive directions of the correlations for several components suggest potential trends worth further investigation.
