Next Day’s PTSS Predicted by the Previous Night’s Sleep Duration, Sleep Quality, Trouble Falling Asleep, and Difficulty Staying Asleep. Note. Least squares means of PTSS, adjusted for demographic characteristics and within-subjects correlations, estimated for each sleep variable with various levels of last night measures, shown as horizontal variables and stratified by different person mean measures. For sleep quality, the four lines of person mean measures reflect the four response options from 0 (Very bad) to 3 (Very good). For sleep duration, trouble falling asleep, and difficulty staying asleep, the three lines of person mean measures reflect the grand mean and one standard deviation above or below the grand mean. The grand means were 5.3, 1.4, 0.53, and 0.36 for sleep duration, sleep quality, trouble falling asleep, and difficulty staying asleep
