Table 6.

Linear regression analyses of parental distress (subscale P-CDI as dependent variable) on children's emotionality, chronotype, actual bedtime, time of lights off, sleep onset time, mothers' sleep quality, and parental expectation discrepancy for the 3 sleep-wake patterns on scheduled days (SC; n = 54).
