Objective
To test the association of home sleep hygiene practices with bedtime resistance among preschoolers, and to determine whether this association differs by child temperament.
Methods
Parents of Head Start preschoolers (n=374, 56% non-Hispanic white) completed questionnaires, including the 5-item Going to Bed subscale of the Children’s Sleep-Wake Scale (GTB; higher score reflects less bedtime resistance), 22-item Children's Sleep Hygiene Scale (CSHS; higher score reflects better sleep hygiene practices) and Child Behavior Questionnaire-Short Form anger, activity, and impulsivity subscales (our measure of difficult temperament). Monte Carlo simulation adjusted for child age, gender, race/ethnicity, and maternal education and tested the association of CSHS with GTB in children with more difficult vs. less difficult temperaments.
Results
Children with more difficult vs. less difficult temperaments experienced worse sleep hygiene practices (p<.0001) and had more bedtime resistance (p<.0001). Among children with more difficult temperaments, better sleep hygiene was linearly associated with less bedtime resistance (GTB β = 1.28, 95% CI 0.77, 1.78). Among children with less difficult temperaments, the association followed a piecewise linear tread: sleep hygiene was not associated with bedtime resistance when CSHS scores were < 4.1 (GTB β = 0.15, 95% CI -4.87, 3.13), but for CSHS scores ≥ 4.1, an increase in CSHS was associated with lower bedtime resistance (GTB β = 1.33, 95% CI 1.00, 1.79).
Conclusions
Consistency in sleep hygiene practices are associated with less bedtime resistance and may be especially helpful in reducing bedtime resistance among children with more difficult temperaments.
