Figure 2. Factor loadings of objective and subjective measures of mothers’ sleep.

Figure 2.

Notes. “Objective” measures are based on nightly actigraphy. “Subjective” measures are based on daily sleep diary responses about nighttime sleep. WASO = wake time after sleep onset. TST = total nighttime sleep time. Factor 1 explained 33% of the variance and factor 2 explained 26% of the variance (var. = variance). Values in each cell are the factor loadings and the color bar indicates the strength of the loading in the positive or negative direction.
