Daily Dynamics of Parental Sleep Quality and Parenting in Chinese Families of Children with Autism Spectrum Disorder

High sleep quality in parents has been linked to positive parenting outcomes, including reduced parenting stress and increased life satisfaction. However, the daily dynamics of these factors remain underexplored, especially in families of children with autism spectrum disorder (ASD). This study examined the reciprocal relationships between daily sleep quality, parenting stress, and life satisfaction among parents of children with ASD. Seventy-five Chinese parents (M = 36.21 years, SD = 3.77 years; 57 mothers) of children with ASD (M = 5.43 years, SD = 1.56 years; 67 boys) participated in a 14-day diary study. Parents reported their subjective sleep quality, parenting stress, and life satisfaction at the same time each day across 7 survey questions. Dynamic structural equation modeling revealed two significant autoregressive effects: parents’ perceptions of parenting stress and life satisfaction on a given day tended to persist into the following day. Moreover, better-than-average sleep quality on a given night predicted lower parenting stress and higher life satisfaction the next day. However, daytime fluctuations in parenting stress and life satisfaction did not influence sleep quality that night. hese preliminary findings suggest a unidirectional impact of sleep quality on perceived parenting stress and life satisfaction among these parents. Target interventions aimed at improving sleep quality, such as cognitive-behavioral therapy for insomnia (CBT-I) or structured sleep hygiene programs, may be essential for reducing parenting stress and enhancing life satisfaction in parents of children with ASD. These interventions should prioritize promoting consistent sleep routines and managing stress-related sleep disruptions.
