Effects of attentional/ hyperactive and oppositional/ aggressive problem behaviour at 14 months and 21 months on parenting stress.

Abstract

To evaluate effects of attentional/ hyperactive (Att/Hi) and oppositional/ aggressive (Opp/Agg) behaviours of children at 14 and 21 months of age on parenting stress at 21 months. 107 children from the general population with low, intermediate, and high levels of disruptive behaviours at 14 months, as evaluated by parents on a 55-item checklist, participated. Parents completed the Child Behaviour Checklist 1.5-5 and the Dutch version of Parenting Stress Index (NOSI) at 21 months. Effects of problem behaviours were examined in a 2 (Att/Hi and Opp/Agg) by 2 (not high versus high) by 2 (14 and 21 months) multivariate design with parental stress as dependent variable. Oppositional/ aggressive behaviour at 14 months had a strong main effect on parenting stress, but not at 21 months. There was a significant interaction between parenting stress and Att/Hi behaviour at 14 and 21 months, indicating that increase in these behaviours over time was associated with parenting stress. Both Opp/Agg behaviour and an interaction between Att/Hi behaviour and parenting stress contributed to maternal role restriction and social isolation. Oppositional/ aggressive behaviour led to higher scores for parental competence and depression, whereas Att/Hi behaviour led to lower scores for attachment. Early Opp/Agg and Att/Hi behaviour had differential effects on parenting stress at 21 months. The increase in parenting stress associated with early Opp/Agg behaviour may be linked to overall feelings of parental competence, whereas the course of Att/Hi behaviour may be associated with increased demands on parent-child interactions and attachment. Our results have implications for development of early intervention programmes.
