This week on the blog, Daniel [EDIT Lab PhD student] summarises the findings of a recently published study by <\/strong>Taraban et al.<\/strong><\/a> investigating the influence of parental depression on the development of behaviour problems in children through its effect on parenting.<\/strong><\/h2>\n

Parenting can be stressful, so it comes as no surprise that around 20-40% of mothers and slightly fewer fathers experience depression during the first year of their child\u2019s life1<\/sup>. Some will already have had depression before their child\u2019s birth, and unfortunately, many go on suffering symptoms for years after. It is well-established that children of depressed parents are at higher risk of developing various mental health problems, but we still don\u2019t know exactly why this is2<\/sup>. There is a substantial body of evidence showing that depressed parents have an impaired ability to be attentive and responsive to their children, and tend to be more irritable and hostile during parent-child interactions3<\/sup>.<\/p>\n

\"\"<\/a>

We aren’t yet sure why children of depressed parents are at higher risk for developing mental health problems.<\/p><\/div>\n

However, we can\u2019t be sure that these factors themselves drive later changes in children\u2019s mental health. An alternative explanation could be that genetic factors that increase parents\u2019 risk of depression are passed on to their child, affecting their later risk of developing depression and other mental health problems. This is called a passive gene-environment correlation, because in biological families, the child\u2019s rearing environment and their genes are provided by the same individuals, their parents. To really understand how parenting and parent mental health affect child development, we have to find ways to measure the complex interplay of genes and environments within families. A great way of doing this is to study children who were adopted at or shortly after birth. This gives us a lot more confidence about what drives children\u2019s development, because birth parents only provide genes and prenatal environments (conditions in the womb), while adoptive parents only provide postnatal environments (parenting and other family factors).<\/p>\n

“To really understand how parenting and parent mental health affect child development, we have to find ways to measure the complex interplay of genes and environments within families.”<\/p><\/blockquote>\n

A recent study used the adoption design to explore the relationship between parental depression, overreactive parenting and child externalising problems in 519 adoptive families4<\/sup>. Overreactive parenting included self-reported irritable, mean or angry responses to child challenges or misbehaviour, while child externalising problems included combined parent reports of children\u2019s behavioural problems, such as destroying others\u2019 things, attacking people and getting into fights.<\/p>\n

\"\"<\/a>

Taraban et al. found that parental depression may lead to overreactive parenting, which itself leads to childhood behavioural problems.<\/p><\/div>\n

The study found that for mothers and fathers, parental symptoms of depression when children were aged 9 months predicted overreactive parenting at 18 months. In mothers but not fathers, this went on to predict child externalising problems at 27 months. Depression itself had no influence on child externalising when accounting for the effects of overreactive parenting. Furthermore, birth mother mental health problems didn\u2019t explain these relationships, suggesting that children weren\u2019t just developing externalising problems due to inherited genetic risk.<\/p>\n

“Depression itself had no influence on child externalising when accounting for the effects of overreactive parenting”<\/p><\/blockquote>\n

The study also looked at social support, an important protective factor for mental health5<\/sup>. Both parents\u2019 satisfaction with their social support was associated with lower levels of depression, overreactive parenting, and later child externalising problems. However, it didn\u2019t affect the relationship between mothers\u2019 depression, overreactive parenting and child externalising. This doesn\u2019t mean social support made no difference \u2013 it just means that mothers\u2019 overreactive parenting predicted later child externalising problems regardless of how satisfied they were with their social support.<\/p>\n

Implications for parenting<\/h3>\n

How do we make sense of these results? The most resounding finding was that mothers\u2019 overreactive parenting, rather than depression itself, consistently predicted later child externalising problems. Importantly, while fathers\u2019 overreactive parenting didn\u2019t predict child externalising, it could still have influenced other child outcomes that weren\u2019t measured in this study. Though results on social support were mixed, the emerging picture was that social support is important in predicting parents\u2019 mental health and its longer-term consequences for parenting.<\/p>\n

“The most resounding finding was that mothers\u2019 overreactive parenting, rather than depression itself, consistently predicted later child externalising problems.”<\/p><\/blockquote>\n

The study had several limitations. For example, the authors noted that findings may have been explained by depressed parents over-reporting their overreactive parenting as well as their children\u2019s externalising problems. They suggested that observational measures of parenting and child externalising could be used to address this in future studies. Another issue is that findings from adoptive families can\u2019t necessarily be generalised to regular families. Adoptive parents tend to be older and have higher incomes, as was the case in this study, so we can\u2019t be sure that the same relationships would be seen in higher-risk or lower-income families. Another limitation was that birth father mental health problems weren\u2019t measured, so children\u2019s outcomes may have been explained by unmeasured genetic factors inherited from fathers.<\/p>\n

Despite its limitations, the study does provide insight into how parent mental health can influence child outcomes through its impact on specific parenting behaviours. The findings could have important implications for screening and targeted interventions for parents whose mental health problems may impact on their parenting and the long-term health of their child.<\/p>\n
