Stress in Mothers with Intellectual Disabilities

Both low parental IQ and stress have been shown to be associated with parenting difficulties and adverse child outcomes. We examined stress in parents with low IQ as a potential contributor to their documented parenting problems. Eighty-two mothers with intellectual disabilities (IQ < 80; labelled as having mental retardation) were given the Parenting Stress Index and they were found to be enduring very high levels of overall stress (95th percentile), stress related to child characteristics (95th percentile), and stress related to other life experiences (90th percentile) as compared to the normative test group. We divided the 82 mothers with intellectual disabilities into three groups depending on the age of their children. The mothers with school-age children reported significantly higher stress than parents of infant/toddler and preschool children. A hierarchical regression analysis revealed that child age and living in a crowded environment were significant predictors of parenting stress. The results confirm that mothers with intellectual disabilities experience extreme stress that, together with other factors, may hinder adequate parenting.
