Background
While parenting interventions have demonstrated benefits for families headed by parents with intellectual disability, they can be costly, time consuming, and have moderate to high rates of drop-out. Furthermore, not all parents benefit from these interventions to the same degree. Little is known about how mediating variables influence learning and skill development in families where a parent has an intellectual disability. Such knowledge is essential to promote best outcomes for the increasing number of children being raised in these families.
The relationship between parent, child, family and contextual variables and intervention outcomes in 120 Australian families headed by parents with intellectual disability were examined in this project. A theoretical model was developed to explain the pathways between context, parenting practices and child well-being for the sample and structural equation modelling was used to test these pathways.
Aim
This project aimed to identify the direct and mediated pathways between family context, parenting practices and child well-being among a group of Australian parents with intellectual disability who has been recruited via the Healthy Start National Strategy (www.healthystart.net.au). The influences upon intervention outcomes for these families were also examined.
Findings
Findings revealed that parenting practices had a direct effect on child well-being, that socio-economic disadvantage, parent health and social support were associated with child well-being via the mediator of parenting practices, and that parent mental health and access to social support had a direct influence on parenting practices.
Cluster analysis of families based on contextual risk indicators that the literature identified as influential to intervention outcomes, revealed two distinct and theoretically discernable groups of parents within the sample. The two clusters differed in parent mental health, partner support, the number of children living at home, child birth weight, child protection involvement and minority status of parents. However, intervention outcomes did not differ for the two clusters. Of the variables that contributed to the clustering of parents, only partner support was found to be associated with program completion. Structural equation modelling was also used to identify that partner support was associated with program completion.
Implications
The implications of the findings reveal that while the socio-environmental context in which the child is embedded is important to child well-being, the pathway via which a child’s wider environment impacts on his or her well-being is via parenting practices. In addition, the findings indicate particular aspects of the contextual environment of families that influence parenting (access to social support and parent mental health), which points to ways in which parenting interventions may be targeted to promote optimal child well-being. Furthermore, it appears that parents with little or no support from a partner are at increased risk for early discontinuation from programs aimed at improving their parenting. Cumulatively these findings have implications for practitioners wishing to target interventions to better meet the needs of individual families. The potential impact of such evidence is threefold: to ensure the highest rate possible of intervention success for all families; to reduce the risk of drop-out from interventions; and to reduce the high rates of child removal from the family.
