Correlation matrix among sleep initiation measures. The correlation matrix displays the relationships among the different measures of sleep initiation. These measures include bedtime, SOL, and SOT measured by self-report, ACT, and PSG. The color and size of each circle represent the correlation coefficient. The p-value for each correlation is indicated in the matrix: *p < 0.05, **p < 0.01,***p < 0.001
