Household chaos and parenting: The effect of household chaos does not depend on sensory-processing sensitivity and self-regulation

Previous studies have found evidence for a causal effect of household chaos on parenting and suggest that this effect may be stronger for parents with higher sensory-processing sensitivity (SPS) or lower self-regulation. This study investigates whether primary caregivers of children around age 1.5-2 years show greater improvement in parenting after a decrease in household chaos if parents have higher SPS or lower self-regulation. The study employs a randomized controlled trial (RCT) design with an intervention aimed at reducing household chaos. A total of 125 parents of toddlers participated in the study. All participants were living in the Netherlands at the time of the study, 89% identified with the Dutch ethnicity and 11% with a non-Dutch ethnicity. Self-report as well as objective measures were used, including videotaped parent-child interactions and home observations. The effect of the intervention on parenting did not depend on SPS or self-regulation. When studying the relation between change in measures of household chaos and posttest parenting, decreased self-reported household chaos was related to less harsh discipline in parents with higher self-regulation, and to more harsh discipline in parents with lower self-regulation. However, this is a tentative finding that should be further explored in future research.
