Wellbeing does not predict change in parenting behaviours among mothers of young children at elevated likelihood of autism

Previous research has generally found lower wellbeing levels among parents of autistic children that were related to fewer positive and more negative parenting behaviours. However, these relationships have not yet been studied before a formal autism diagnosis is given. The present study investigates wellbeing (including positive mood, vitality, and general interest) and its relationships with a range of parenting behaviours among two groups of mothers with children at elevated likelihood (EL) of autism: mothers of younger siblings of children on the autism spectrum (‘siblings’; n = 81) and very or extremely prematurely born children (‘preterms’; n = 40). Growth curves were modelled to investigate whether wellbeing and EL group were associated with (change in) reported parenting behaviours between 10 and 24 months of child’s age. As expected, we found more stability than change in parenting behaviours, and more similarities than group differences in parenting behaviours and wellbeing. Mothers generally reported more disciplinary behaviours when their child grew older, in line with general population findings. Initial levels of supportive behaviours were equally high among mothers of siblings and preterms, but only mothers of preterms reported an increase over time. Wellbeing levels were largely comparable to those of a matched subsample from the general population, contradicting previous findings. Contrary to our hypotheses, wellbeing was not associated with fewer positive or more negative parenting behaviours. This is encouraging, as all children benefit from supportive and responsive behaviours.
