Figure 3. Associations of mothers’ objective sleep continuity with linear change in maternal sensitivity across the “free play” interaction.

Figure 3.

Notes.: Mothers’ objective sleep continuity is operationalized as a standardized sum of the actigraphy measures of WASO and number of arousals. Maternal sensitivity was observationally coded in two-minute intervals across the ten-minute “free play” interaction. Simple slopes are the estimated associations between free play interval and maternal sensitivity at +1SD from the mean of sleep continuity (blue), the mean of sleep continuity (grey), and −1SD from the mean of sleep continuity (red). Poorer sleep continuity was associated with significant decreases in sensitivity across the interaction.
