​​How Are Early Childhood Irritability and Tantrums Related to Future Depression and Self-Harm?​

A study opens in new tab/window in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP), published by Elsevier, reports that children whose irritability did not improve during early childhood experienced higher levels of depression and self-harm as teenagers.  

Irritability and tantrums are normal during the toddler/preschool the preschool years and parents sometimes refer to this age group as the ‘terrible twos’ and ‘threenagers’.’For most children, irritability improves as they grow older. However, some children continue to struggle with irritability and behavioral outbursts as they grow older. Although previous research showed that irritability in later childhood increased the risk of future depression, it was not known whether irritability during early childhood is similarly important. Identifying a marker for increased risk earlier would give us greater opportunity for devising preventive interventions.   

This study is based on data from over 7,000 children who participated in the Millennium Cohort Study: a contemporary, nationally representative UK birth cohort. Parents answered questions about their child’s irritability at 3, 5, and 7 years, and teenagers reported depressive symptoms and self-harm at 14 years. This study found that children with irritability that did not decrease between the ages of 3 and 7 years experienced higher levels of depression and self-harm in adolescence, whereas irritability at 3 years only was not associated with later depression.   

Study author, Dr Ramya Srinivasan, a clinical research fellow in child and adolescent psychiatry at University College London says, “This study suggests that while some degree of irritability is part of normal child development, we can identify children who struggle with persistent irritability from as young as 5 years, thus providing an opportunity for prevention and early intervention”.  

She adds, “The findings emphasize the importance of early childhood for emotional development. Support for parents of young children has been reduced in many countries in recent years and was substantially disrupted by the Covid-19 pandemic. This is concerning and a possible missed opportunity.”
