Individual and family factors associated with child mental health and wellbeing

Introduction

Child mental health encompasses a child’s emotional, social and psychological wellbeing (Emerging Minds, n.d.)¹. Understanding what factors are associated with child mental health challenges or promote wellbeing is important for practitioners and services who work with children and families². This understanding can help practitioners to identify children in need of more support by indicating who may be at higher risk of developing mental health challenges or how best to respond to existing mental health challenges (Eriksson, Ghazinour, & Hammarström, 2018). It can also provide opportunities to intervene early to prevent challenges arising (Eriksson et al., 2018). For example, programs and policies can be designed for children or their families that target these factors and consequently promote child mental health.

Children’s mental health and wellbeing can be influenced by a range of factors relating to the characteristics of the individual child, their family and relationships, and the community and society that they live in (Eriksson et al., 2018). This resource summarises the evidence on the individual and family factors that research reviews have found are associated with child mental health outcomes and outlines related implications for practice. These are the factors that services working with children and families are most likely to influence and are also those that have been most extensively researched.

This article does not provide an exhaustive list of all factors associated with child mental health but instead focuses on those that are the most well researched and where the recent evidence is strongest. Some emerging factors, or previously established factors that have not been included in recent reviews of the evidence, may not be covered in this article.

Individual factors associated with child mental health

The term ‘individual factors’ refers to the characteristics of an individual child such as their age, biological sex, personality or behaviour. Table 1 outlines the individual factors examined in research reviews of the evidence on child mental health. It shows the impact of each factor on different child mental health outcomes.

Of the several individual factors associated with child mental health, self-regulation³ – which refers to a child’s ability to understand and manage their emotions and behaviours (Raising Children Network, 2024) – is one that has most consistently been associated with a reduction in child mental health challenges. The evidence is strongest for improved self-regulation having a relationship to reduced externalising and internalising behaviour (Table 1). Self-regulation may therefore be a good factor to target for programs addressing child wellbeing because it is associated with a reduction in the likelihood of a child experiencing multiple mental health challenges.

Table 1. The association between individual factors and child mental health outcomes

Family factors associated with child mental health

The term ‘family factors’ refers to the characteristics of the child’s caregiver⁴, such as their parenting skills, behaviour and health, as well as the family’s functioning. This can also include the parent–child relationship and family conflict.

Table 2 shows family factors that have been identified in previous evidence reviews and their association with different child mental health outcomes. Parenting skills, child maltreatment and childhood exposure to intimate partner violence are examples of factors that were associated with a range of child mental health outcomes in multiple evidence reviews. As a result, there appears to be stronger evidence for these associations. More details about these factors are described below.

Parenting skills⁵ – a term which refers to caregiver knowledge, behaviours and abilities that enable them to care for their child (Hurley et al., 2014) – were found to improve child mental wellbeing and reduce mental health challenges in multiple research reviews. Parenting skills were associated with an increase in adaptive behaviours and social functioning in children (Table 2). They were also associated with a decrease in children’s externalising and internalising behaviours, behavioural difficulties, emotional difficulties and anxiety symptoms. The evidence for the impact of parenting skills was strongest for the reduction of externalising, internalising and behavioural difficulties. Parenting skills may therefore be a useful factor to target in interventions that aim to reduce these child mental health challenges.

Multiple evidence reviews also found that child maltreatment and childhood exposure to intimate partner violence⁶ between caregivers, which is sometimes considered a type of child maltreatment, both have a negative impact on child mental health (Table 2). Child maltreatment was associated with an increase in anxiety, depression, externalising behaviour, internalising behaviour and post-traumatic stress disorder. Childhood exposure to caregiver intimate partner violence was also associated with decreased emotional regulation, self-regulation and social competence. Children with these experiences are likely to require additional follow-up and supports to screen for mental health challenges. Including child maltreatment and exposure to caregiver intimate partner violence in general screening may also help with early identification of potential challenges and support opportunities.

Implications for practice and services

Given the strong evidence for the influence of individual and family factors, the following considerations may be useful for practitioners and services in supporting child mental health.

• Recognise that a child’s mental health can be influenced by factors related to their characteristics, personality and behaviour, and the behaviour, skills and functioning of their caregivers and family. The whole child and their relationships should be taken into consideration when working with children and their families.
• Factors that can influence child mental health, and that can potentially be modified, may be useful targets for interventions aiming to improve child wellbeing and reduce mental health challenges. These include the child’s ability to self-regulate, level of behavioural inhibition and resilience, and their quality of sleep. They can also include caregivers’ parenting skills, mental health (e.g. via support for parents), and prescription or illicit substance use.
• Factors that can influence child mental health but cannot be readily modified via support from practitioners (e.g. past experiences of child maltreatment, previous exposure to caregiver intimate partner violence, very low birth weight), may be indicators that can help practitioners and services identify children and families that may need additional mental health support. Practitioners should be mindful that the presence of these factors doesn’t mean that a child will always experience mental health challenges.
• Where possible, practitioners can also consider their role in primary prevention of individual and family factors that contribute to mental health challenges (i.e. prevention of factors before they occur). For example, this could include providing expectant parents with adequate mental health support or teaching children self-regulation skills from a developmentally appropriate early age.

Conclusion

This resource summarised the evidence on individual and family factors that are the most well researched and where the evidence is strongest for their association with child mental health. These factors may be useful targets for interventions aiming to reduce child mental health challenges and improve mental wellbeing. They could also help practitioners and services identify which children and families may need additional support. In addition to the factors explored in this article, there are likely other factors that are less well-researched but may influence child mental health.

How was this resource developed?

This resource is based on a review conducted by the Australian Institute of Family Studies (AIFS) for Emerging Minds. As part of the review, a search was conducted to identify systematic reviews and meta-analyses on factors associated with child mental health. The search was conducted in April 2021 in the Australian Family & Society Abstracts database, the Campbell Systematic Reviews and the Cochrane Database of Systematic Reviews. Terms related to ‘child’, ‘mental health’ and ‘review’ were searched for in these databases. Included reviews were 1) published in a peer reviewed journal from 2011–2021, 2) written in English, and 3) focused on children aged 0–12 years.

Although the original search conducted for the AIFS review was comprehensive, it lacked the sensitivity to identify reviews on the association between child mental health and some of the identified factors of interest (i.e. domestic and family violence, child maltreatment and adverse childhood experiences). As such, a specific search for reviews on these factors was conducted in Google Scholar on 30 July 2024 using terms related to ‘violence’ in addition to ‘child’, ‘mental health’ and ‘review’. The inclusion criteria for reviews of these factors were also expanded to include children up to the age of 18 years (as opposed to 12 years for the original search).

Grey literature was not included. As only reviews of the evidence were included (i.e. not original research studies), some emerging evidence on individual and family factors associated with child mental health may not be included.
