Policies are Needed to Increase the Reach and Impact of Evidence-Based Parenting Supports: A Call for a Population-Based Approach to Supporting Parents, Children, and Families.

Parents can be essential change-agents in their children's lives. To support parents in their parenting role, a range of programs have been developed and evaluated. In this paper, we provide an overview of the evidence for the effectiveness of parenting interventions for parents and children across a range of outcomes, including child and adolescent mental and physical health, child and adolescent competencies and academic outcomes, parental skills and competencies, parental wellbeing and mental health, and prevention of child maltreatment and family violence. Although there is extensive research showing the effectiveness of evidence-based parenting programs, these are not yet widely available at a population level and many parents are unable to access support. We outline how to achieve increased reach of evidence-based parenting supports, highlighting the policy imperative to adequately support the use of these supports as a way to address high priority mental health, physical health, and social problems.

Parents and caregivers have a central role in optimizing their children’s development and wellbeing. Parenting practices are a very important modifiable factor for optimal child development [1]. Child emotional and behavioural problems are prevalent in the population, and are predictive of a range of physical and mental health problems into adulthood [2-4]. Family risk factors show considerable variation across communities and nations. Children are at greater risk for the development of emotional and behavioural problems, as well as child maltreatment, if they grow up in family environments that are conflicted, poorly managed [5] or harsh, punitive, and/or unpredictable [6-8]. Large child population improvements have been demonstrated through parenting changes [5]. To improve parenting practices and optimize child development, a range of parent education and support programs have been developed and evaluated. Parents and caregivers are critical change-agents when intervention is required. Parenting practices can be changed through evidence-based parenting supports (EBPSs) with benefits seen for both parents and children (e.g., [9-12]). For example, in early childhood, EBPSs are the most efficacious interventions for emotional and behavioural problems and this has been demonstrated across diverse cultural and service contexts and populations [13-16]. EBPSs also are effective at changing parenting behaviours [15, 17–22] and reducing child maltreatment risk [23-25], which addresses key environmental risk factors. Despite positive benefits to children and families [26], the access and reach of EBPSs varies across communities and remains limited in both low- and middle-income countries (LMICs) and high-income countries (HICs) [27]. In order to improve the access and reach of evidence-based prevention and intervention programs to address childhood mental health and behavioural problems and the prevention of child maltreatment, broad implementation and population-level reach of EBPSs is warranted.

Population-level reach of parenting support involves a blended model of parenting support that combines universal and more targeted approaches with the level of support being proportionate to need (i.e. employing the principle of proportionate universalism [28]). Population-level reach of EBPSs can be achieved by offering multiple levels of support, from light touch to more intensive, that relate to what the parent or caregiver is seeking and has the capacity to engage with [17]. A population-level approach to providing EBPSs also means there is not a one-size-fits-all or one single pathway into receiving an evidence-based parenting program. Principles of minimal sufficiency and proportionate universalism avoid over-serving and recognise that most people are likely to benefit from low-intensity EBPSs that are not costly to deliver at a population level [28]. This approach is also suggested in the World Health Organization’s Nurturing Care Framework [29]. A population-level approach from EBPSs using minimal sufficiency (i.e. the least amount of intervention needed to address the presenting problem and prevent future difficulties) and proportionate universalism is considered much more efficient than a stepped care approach as a population-level approach avoids expensive population screening, ensures that parents and caregivers get what they are looking for, and enables parents and caregivers the option to enter, leave, re-enter, and leave depending on their changing needs as their children develop [30].

Population-level reach also allows for a de-stigmatised offering of EBPSs that all parents and caregivers are able to participate in, that is, not simply offering EBPSs to vulnerable and/or high-risk populations [30, 31]. In order to adequately support populations at high-risk for child emotional and behavioural problem and child maltreatment, universal offerings of EBPSs have been recommended in order to achieve a shift in the needle at the population level for community-wide problems like child maltreatment [31]. Universal offerings of EBPSs do not mean universal uptake of EBPSs (unless such uptake is mandated). Studies that have demonstrated a population-level effect of EBPSs have never reached more than a quarter of eligible parents [32, 33]. The effects at a population-level of universally available EBPSs occur through a number of mechanisms. In some cases participating parents and caregivers “share the word” and model effective practices with non-participating parents and caregivers in their communities (i.e. social contagion) [33]. In environments, such as schools, population mechanisms may involve EBPSs reducing risk factors such as peer substance use [34] and increasing protective factors such as family management and community monitoring of children [35]. For example, population-level benefits have been observed in population samples despite only a small proportion of the sample being exposed to the EBPSs [33, 34].

Despite all of this evidence, policies do not seem to support the broad implementation and population-level reach of EBPSs in most countries, and certainly not in any LMIC [36]. The majority of the world’s children who might benefit from their caregivers participating in EBPSs live in countries where accessing such programs is not a policy priority [36]. It therefore appears that there is a gap between what is known in the literature and what policymakers know. In this paper, we aim to outline the evidence highlighting the importance of parents for optimizing children’s healthy development, summarise the evidence that EBPSs improve a broad range of child and parent outcomes, and provide policy recommendations that advocate for better support for parents and improve access to EBPSs. This paper is not a systematic literature review, but a manuscript summarizing relevant literature for the goal of explaining the importance of overcoming barriers to a population-based approach to parenting support.

We believe that we are uniquely placed to be able to bridge this gap. As Daly [37] highlights in her analytic framework examining parenting support as a policy field, there are a range of political actors expected to promote parenting support—with a core set of actors being those in the academic and quasi-academic research community. Indeed, we are part of this community: the Parenting and Family Research Alliance (PAFRA) was formed in 2020 with the vision to advocate for parents and parenting research, and to increase the reach of evidence-based parenting support programs in Australia and internationally. PAFRA is a multidisciplinary research collaboration bringing together leading Australian researchers from a variety of universities and research centres. Although some researchers and policy commentators have written that EBPSs—and policies that support EBPSs—are a type of governance of ‘private life’ (e.g., [38]), PAFRA’s position is that parents are critical to optimizing child developmental outcomes, that parents need to be provided with a range of options for being able to develop their parenting knowledge and skills, and that greater access to EBPSs should be a policy priority. Thus, this position underlies this paper and our advocacy to increase the reach EBPSs in Australia and internationally.

The Importance of Parents for Optimising Children’s Healthy Development

Parenting matters for children’s optimal development [1, 39, 40]. Recently, the World Health Organization announced that they are developing guidelines on parenting to prevent child maltreatment and promote positive development in children aged 0–17 years [41]. Parenting and family functioning has been associated with many very high burden-of-disease problems, including mental illness; alcohol and drug abuse; crime and violence; childhood injury; obesity; chronic disease; and educational and economic failure [42, 43]. Child mental health problems are associated with insecure attachment; the lack of a warm and positive parent-child relationship; harsh, inflexible, rigid, or inconsistent discipline practices; and inadequate supervision of, and involvement with, children (e.g., [44]). Research has also shown that antisocial parental behaviour and depression both have an environmental influence on child psychopathology, even when genetic factors are accounted for [39]. Positive parental interactions are associated with optimal development for children, such as more secure attachment, higher capacity for self-regulation, increased language development, improved communication and cognitive development, and greater prosociality [45, 46].

Yet parenting is complex and multidetermined; as can be seen in Fig. 1. What is regarded as optimal parenting, for example, changes according to the child’s developmental stage and competencies [44], as well as cultural and contextual circumstances [40]. Parenting practices therefore need to evolve throughout the lifespan to stay appropriate and effective [44]. Parents have differing parenting knowledge and skills, which are further influenced by a variety of contextual issues (e.g., child temperament and characteristics, parent self-regulation and parent cognitive functioning), the cultural setting in which they parent, and broader social determinants of health (e.g., chronic and acute stressors that impact family functioning and parenting). The difficulty of the parenting role can be exacerbated in communities that are unsafe (e.g., historical and ongoing trauma) and/or dominated by unhealthy markets (e.g., alcohol, tobacco, illicit drug sales); that lack coordinated parenting services and resources; and, where there is intergenerational transmission of problems (such as unemployment, poverty, crime, and alcohol and other drug addictions). Consequently, parents may become socially isolated, disconnected from the community, overwhelmed, and disempowered, and children are disadvantaged. In order to optimise the wellbeing of children and families, and particularly those living in contexts of disadvantage, caregivers need to be supported to parent as well as possible in order to optimise children’s development [40, 48].

Fig. 1

Multiple determinants of parenting practices [47]

Parenting does not just affect children, but parenting competence or self-efficacy also influences parents themselves [47]. The extent to which parents view themselves as competent in their parenting role is associated with parental wellbeing, the use of positive parenting practices and optimal child outcomes [44]. There are a range of collateral effects of EBPSs on parent mental health and health outcomes [21, 49–51]. For example, there has been reductions in maternal depression that have been associated with improved parenting skills [52]. EBPSs offer a way to support parents in their parenting role.

Outlining the Evidence that EBPSs Improve Child and Parent Outcomes

EBPSs refer to “the full breadth of empirically supported means of helping parents raise their children. These means of support include communication messaging as part of a social marketing campaign, the use of low and higher intensity parenting interventions using the Internet, and group and individual face-to-face delivery of parenting interventions” [46].

Evidence-based parenting supports differ from evidence-informed parenting supports as they have been empirically evaluated to be effective in significantly changing outcomes to benefit children and/or parents. Comparatively, evidence-informed parenting supports may be formulated with evidence in mind but have not been empirically tested. EBPSs provide a higher level of evidentiary support than evidence-informed parenting supports that can be difficult to define and reach agreement on. Although evidence-informed parenting supports may be useful for populations that are hard to reach and where an extensive evidence base has not been established (e.g., families with complex trauma, indigenous communities), the majority of parenting populations should be provided with EBPSs where the empirical evidence is overwhelming.

Decades of research and numerous meta-analyses have established EBPSs to be acceptable to parents in diverse cultural contexts [53], and to produce positive effects in terms of parent behaviour, child behaviour, parental adjustment, and family relationships (e.g., [9–12, 16]). There is also evidence from systematic reviews and meta-analyses that EBPSs work in both HICs and LMICs, with findings suggesting that EBPSs are at least as effective when transported to countries with different cultures and service provisions than those in which the EBPSs were developed [16, 54]. EBPSs also provide a mechanism through which the United Nations Sustainable Development Goals may be attained, as positive parenting practices can promote diverse prosocial outcomes in children and parents [36, 55].

As previously outlined, policies do not currently support the broad implementation and population-level reach of EBPSs in HICs or LMICs. In this paper, we have presented a range of illustrative examples demonstrating the effectiveness of EBPSs across a range of domains/outcomes relevant to child and family wellbeing in Table 1, so that the evidence for why broad implementation and population-level reach of EBPSs in HICs and LMICs might be warranted. It is also possible, however, that there are several other reasons why policy makers do not currently use EBPSs to address societal problems. As Ramsey and colleagues note effectiveness of the intervention is but one factor in a more complex equation in the research-translation calculus [56]. There may be a problem with the dissemination of EBPSs, for example. There might also be an issue with the framing of using EBPSs by policy makers to create the type of value propositions that they are willing to use their political will to get into policy. It is possible that researchers need to continue to consider how to address these problems when attempting to translate the use of EBPSs and widely disseminate EBPSs.

Illustrative exemplars that capture the breadth of diverse outcomes influenced by EBPSs

Domains/outcome areas	Brief commentary
Parental skills, knowledge and confidence	- There is extensive evidence supported by meta-analyses and systematic reviews for EBPSs resulting in improvements in parenting skills [15, 17–22, 26], self-efficacy [15, 17, 57–59] and knowledge [18, 20, 26, 60] across a variety of settings and formats for parents of typically developing children in HIC - There is also evidence that EBPSs improve parenting skills, across a variety of settings and formats for parents of typically developing adolescents in LMICs [61] and HICs [62] - In regards to parents with a child with developmental disabilities, meta-analyses have found that EBPSs result in improved parenting practices, parenting satisfaction and efficacy, parental adjustment, and co-parent relationships [14, 63]
Child and adolescent mental health	- There is extensive evidence supported by meta-analyses and systematic reviews for EBPSs resulting in improvements in behaviour problems for children aged less than 12-years-old [15, 17, 20, 21, 26, 59, 64] and adolescents [62] across a variety of settings and formats [15, 65] - Evidence shows that EBPSs can reduce internalising problems [65, 66] - A review of EBPSs for parents of adolescents in LMICs demonstrated that several EBPSs improved adolescent psycho-social wellbeing, including reduced internalising and behavioural problems [61] - Meta-analyses have found treatment effects of EBPSs for both mixed and specific disability samples, including children with attention-deficit/hyperactivity disorder [67], autism spectrum disorder [68], language impairments [69], and parents with intellectual disability [70]
Parental wellbeing and mental health	- There is compelling evidence supported by meta-analyses that EBPSs that focus on reducing child behaviour problems have demonstrated improvements parental mental health, including reductions in depression, anxiety and stress (e.g., [21]) - There is also emerging evidence from reviews that mindfulness-based parenting programs show significant benefits in reducing parental depressive symptoms [49], and parental stress [51] - Further, there is developing evidence from a systematic review and meta-analysis that EBPSs for children with chronic illness result in improved parental mental health [50] - An evaluation of a population-level approach for EBPSs focussing on supporting families with children with developmental disabilities found that increased access to parenting support resulted in significant improvements in a range of indices of family functioning [71]
Child and adolescent academic attainment	- There is emerging experimental and quasi-experimental evidence that both intensive and light-touch EBPSs during the preschool years can increase academic achievement in primary school (e.g., [72, 73]) - There is also evidence that EBPSs provided in the early years (before children are aged 3-years) result in significant improvements in child cognitive development, language development, and motor development; and these effects were greater in LMICs than HICs [26]
Child and adolescent competencies	- There is strong evidence that EBPSs have been found to improve emotional and behavioural development for children aged 3- to 12-years-old [64]. Currently, there is limited high quality evidence to demonstrate these benefits in children under 3-years-old [64] - As outlined in a review of systematic reviews [74], there is good evidence that EBPSs improve social outcomes for children including parent-child interactions, children’s social skills and social competence, emotional stability, and self-control - In their review, England-Mason and Gonzalez [75] found that a handful of emotion socialisation parenting programs had demonstrated improvements in children’s skills in understanding and regulating emotions - In terms of child outcomes for children with a disability, meta-analyses have shown that EBPSs are associated with improvements in child communication skills, social, and other adaptive behaviours [76], as well as reductions in challenging behaviours [14, 63]
Child and adolescent physical health	- There is emerging evidence for the efficacy of EBPSs for parents of children with a chronic health condition. One systematic review [77] has indicated that EBPSs may lead to improved parent self-efficacy, parenting behaviour, illness severity/control, child quality of life and child behaviour; however, intervention effects were mixed and confined to parent-report outcome measures - There are promising outcomes reported across multiple systematic reviews of EBPSs for childhood overweight and obesity. Reductions in weight have been demonstrated in treatment studies [78, 79], in studies delivered during the perinatal period [80], and universally delivered parent support [81], but not for eHealth interventions [82] nor prevention studies [78] - There is promising evidence of efficacy supported by systematic reviews for EBPSs that target children’s dietary behaviour [80–83] - A systematic review of EBPSs targeting infant sleep also showed small improvements in infant sleep [84] - Systematic reviews also demonstrate that EBPSs can prevent adolescent alcohol, tobacco, and illicit drug use over the short- and long-term [85–88]
Prevention of child maltreatment and family violence	- Meta-analyses and reviews have shown a significant effect of EBPSs in preventing or reducing maltreatment [23–25], including in LMICs [54] - Although there is conceptual alignment between the provision of EBPSs and the prevention of child maltreatment and family violence, relatively few RCTs examine outcome measures relating directly to child maltreatment and family violence [55]. The majority of the available evidence relates to physical abuse and neglect often in HICs [55]. Barlow et al. [64] found there was good evidence of modest benefits in improving outcomes associated with physical abuse and neglect, such as parent and family functioning and child development - In a review of the evidence on EBPSs in LMICs at preventing and reducing maltreatment and family violence, it was shown that EBPSs can be effective in reducing violence (physical and emotional) and neglect of adolescents, and increasing parental capacity to protect children from sexual violence [89] - In a rare study of population-level effects, Prinz et al. [32] used randomisation of the intervention (a tiered, multi-level approach to parenting support) compared to usual services. They found that provision of EBPSs led to significant reductions in rates of confirmed child maltreatment cases in the statutory child protection service, out-of-home care placements, and hospital-treated child maltreatment injuries - Despite the theoretical alignment, there is a lack of studies examining the role of EBPSs on preventing domestic violence [90, 91] and the documented impact of interparental conflict, domestic and family violence on parenting and parent–child relationships [92]. A scoping review of EBPSs in LMICs that aim to prevent domestic violence and child maltreatment found that there was limited but emerging evidence that EBPSs can produce positive outcomes for caregivers and children [91]

Implications for Policy

Decades of parenting research have resulted in a wealth of knowledge about the importance of parents as change agents in children’s lives and the effectiveness of EBPSs (as shown in Fig. 2). Although the list in Table 1 is illustrative, and not exhaustive of all the evidence on EBPSs, it is clear that EBPSs positively affect a range of parent and child outcomes including: parental skills, knowledge and confidence; child and adolescent mental health; parental wellbeing and mental health; child and adolescent academic attainment; child and adolescent competencies; child and adolescent physical health; and prevention of child maltreatment and family violence.

Fig. 2

Benefits of evidence-based parenting supports

Parenting interventions have an extensive evidence base, yet their availability is often limited and relatively few parents access EBPSs [27, 40]. In Australia, for example, only 35% of parents who had a child needing help for an emotional or behavioural problem reported having their needs fully met [93]. Similarly, in the United States, less than 50% of youth with severely impairing emotional, behavioural, or developmental disorders had never received intervention [94]. Few policies adequately support the use of EBPSs as a mechanism to support parents and children across the world. It is therefore necessary that policies enable access to EBPSs so that children, parents/carers, and families are supported (see Fig. 3).

How to enable access for parents and carers

Theory of Change

The “theory of change” from a public health perspective is that children are more likely to follow an optimal development pathway when experts effectively communicate healthy behaviour guidelines to all parents (e.g., child nutrition, activity, online behaviour, violence against others). Parents then need opportunities to improve their skills, capabilities, and confidence using EBPSs that are delivered through trusted (non-stigmatised) universal service delivery platforms. Parenting capability can then be further supported by access to more targeted services based on a progressive approach. This blended model of parenting support combines universal and more targeted approaches with the level of support being proportionate to need (i.e. employing the principle of proportionate universalism [28]) and being minimal sufficient (i.e. providing the least amount of intervention needed to address the presenting problem and prevent future difficulties). As well as providing lower-intensity EBPSs to the broadest group of families, more intense supports are needed for those with the highest level of need. These include supports to families delivered at the tertiary level (i.e. statutory child protection services, where harm is imminent or has occurred) where parenting deficiencies (i.e. risk factors for child maltreatment) are clearly apparent. This approach normalises parent education and support at the community level, an important factor for improving engagement in, and use of, EBPSs by parents. Such an approach would involve changes to policy, funding, and practice to ensure that EBPSs are available at the primary prevention level in order to reach the greatest number of parents and families. This population-based approach to implementation of EBPSs can be applicable to both HICs and LMICs. The evidence shows that EBPSs can be effectively transported into a variety of countries; which includes settings in which the EBPSs were not initially designed, in low-resource contexts, as well as settings with high violence rates [16, 17, 54, 89, 95, 96].

The delivery of EBPSs needs to be flexible, with support being offered in traditional in-person services, as well as utilising telehealth and online delivery. Although funding for flexible delivery options was always important to ensure reach to rural and remote families [97, 98], increasing funding for flexible delivery of EBPSs has been of particular importance during and following the COVID-19 pandemic. This is because COVID-19 health priorities (e.g., social distancing measures) have necessitated that in-person services be ceased or reduced, even if only temporarily. Policy makers do not need to be concerned about effectiveness of EBPSs when flexibly delivered, as researchers have already established that technology can be effectively used to deliver parenting support. For example, recent reviews have demonstrated effectiveness for online EBPSs [99, 100]. Moreover, studies have shown that therapist-assisted EBPSs using telephone contact [101, 102] and online video conferencing [97, 98, 103, 104] have been effective at improving child outcomes (and sometimes parent outcomes too), with high levels of parent satisfaction reported. Researchers have also shown that therapist-assisted EBPSs using online video conferencing are as effective as face-to-face EBPSs [97, 103].

Funding of EBPSs

A major barrier to increasing the reach of EBPSs is how these programs are funded in different nations. For example, in Australia, children and adolescents with defined mental health conditions cannot receive a government-funded evidence-based parenting intervention delivered by authorised practitioners because of an anomaly that requires the child to be physically present in a mental health consultation. Removing this barrier to enable parent-only consultations would enable the delivery of several EBPSs. Similarly, as outlined by Weisenmuller and Hilton [105], there are similar challenges in the United States where the provider contracting system results in a service delivery environment that is complicated by insurance coverage (e.g., Medicaid versus private), insurance plans, and whether insurance-provider agreements exist. Comparatively, these funding barriers are not seen in many European nations (e.g., The Netherlands, Germany) where EBPSs are funded by the state. Policy makers need to address funding barriers so that parents are able to access EBPSs.

Some administrations also state they fund programs deemed “evidence-based”, but the metrics for this classification vary greatly. Lack of transparency and accountability in the funding of parenting programs is also a major obstacle to accessibility. It can be challenging to establish whether policies are effectively dedicating funding to evidence-based or evidence-informed parenting supports. In some areas of mental health support, it makes sense that evidence-informed practices and practitioners are funded so that timely solutions to important problems can be provided. However, when there is an extensive evidence base regarding what works for parents and children, it makes little sense for funding to be directed to evidence-informed parenting supports rather than to evidence-based parenting programs.

To date, funding for EBPSs has often been piecemeal. It is almost impossible to find out how much is spent by governments each year on the delivery of EBPSs. With no clearly defined line items in government budgets, it is impossible to know whether funding for EBPSs is improving, stable, or decreasing. Policy makers therefore need to ensure that they are directing funding to EBPSs in a transparent way that promotes accountability. We argue that to achieve wider take-up of EBPSs, a multi-level, progressive approach based on a public health or population-based model is needed (as outlined in [31, 106]). In order to influence the bulk of the population of families, the greatest investment should be in universal primary prevention activities located within service settings that are widely available [31]. Traditionally, EBPSs have mainly been delivered through referral to mental health, specialised education, and mandated social welfare contexts, and delivered in person. Yet there are other untapped and understudied opportunities to positively influence the parent–child relationship. To influence the bulk of the population of families, policy makers need to ensure that they are funding multiple non-stigmatising “soft-entry” points for parents. “Soft-entry” points could include (a) universal services, like education and primary health care; (b) organisations that families are already in contact with, such as early childhood settings, schools, community sporting organisations, religious organisations, music and artistic activities, and general practice medical services; as well as (c) social welfare and dedicated referral services [106].

An additional barrier to improving the reach of EBPSs is an assumption that there is a one-size-fits-all approach to parenting support. There are a range of EBPSs based on different theoretical orientations, use a variety of delivery modalities, and cater for differing parents’ needs, values, and preferred parenting practices. The evidence shown in Table 1 indicates that EBPSs can effectively be tailored at the culture-level and many other broad participant-level groupings. There are also EBPSs, such as the Family Check-Up, which tailor the intervention at the family-level [107, 108]. Parents should be provided with some level of choice so that they can find an EBPS that fits their approach to parenting as well as the EBPS that meets their cultural/religious/family-level needs; this is, provided equally strong evidence for equally strong program effects. However, access to a range of EBPSs remains limited in HICs and LMICs. Inclusivity is also needed, such that all relevant caregivers are able to participate in EBPSs appropriate to their needs [97, 109]. This includes parents from the LGBTIQ + community; fathers [110]; parents of children with developmental disabilities; parents in rural and remote settings; and parents from ethnically and culturally diverse groups, including Indigenous parents.

Funding Research on EBPSs

Given the crucial importance of parenting and EBPSs, we believe it is alarming that only a small proportion of research funds focus on the continued advancement of evidence for EBPSs and the implementation of EBPSs, with some areas barely attracting government funding. We do not raise this point to feather our nests, but rather to highlight that for population reach to be realised, further consideration is needed regarding for whom, in what context, and in what combination, different EBPSs work. None of the currently available programs are a panacea and there are non-responders to every intervention. Further research is needed to identify how to further attract parents to engage in EBPSs, the variables that influence response to intervention, and the mechanisms of change underlying specific interventions, in order to inspire innovation in the development and translation of EBPSs. Focussed research is also needed on the implementation of EBPSs in ways that are efficient, cost-effective or cost-neutral, and how to get systems to adopt the use of EBPSs [111].

Research can only be conducted if there is funding to support it. In a recent review of Australian federal government competitive research grant schemes from 2010 to 2020, it was found that less than 1% of funding awarded by the Australian Research Council and the National Health and Medical Research Council was for parenting intervention research [112]. Of those studies awarded funding, each targeted between one and four of the outcome domains outlined in Table 1 [112]. Some outcomes attracted more funding (i.e. those with outcomes of child physical health, and child mental health) whereas others attracted substantially less (i.e. those with outcomes of prevention of child maltreatment, and improving child and adolescent academic achievement).

The reasons EBPSs attract such a small proportion of the research and service delivery funding budgets remain unclear. It may be due to a misunderstanding by policy makers and reviewers of the broad range of impacts that EBPSs touch, or viewing EBPSs as governance of ‘private family life’ [38]. Alternatively, it may be because within the wider population, parents are not viewed as important “change agents” for enhancing the wellbeing of children, preventing the development of difficulties, and reducing clinically diagnosed disorders. We believe this view needs to change in HIC and LMICs. In LMICs, policy makers may have concerns that parenting interventions are very costly, or they do not believe that they work in settings with high violence rates [89]. Concerns about effectiveness in LMICs may be at odds with the evidence (for example, EBPSs can be effective in reducing violence and neglect of adolescents in LMICs [89]), yet such beliefs may still remain a barrier to implementation in LMICs. It may also be unclear to policy makers where the onus of responsibility lies for delivery of EBPSs, that is, whether they should they be delivered via health, education, child protection, criminal justice or other government portfolios. This lack of clarity means parenting research sits outside any direct source of research funding. A silo-based approach to funding of research appears to make little sense when many EBPSs impact diverse outcomes that cut across several different government portfolios and policy agendas.

Ensuring Workforce Readiness

A further challenge in extending reach of EBPSs is ensuring that there is a workforce able to readily implement these programs. Most helping professionals receive little training in EBPSs in their discipline-specific professional education. Psychologists, social workers, nurses, general practitioners, paediatricians, educators and counsellors would all benefit from better pre-service training, specifically systematic skills-based training in a least one EBPS model. The impact of COVID-19, requiring a pivot to online training, may provide additional avenues for training of parent support practitioners. Professional associations that develop guidelines for university-based training should therefore consider adding guidelines to ensure the inclusion of systematic skills-based training in at least one EBPS model.

To close the access gap, it may also be necessary to expand the interprofessional, non-professional, and potentially lay workforce for EBPSs [105]. For example, there is evidence that EBPSs can be provided effectively by early childhood educators [113], and trained interprofessional volunteers (e.g., those with a relevant background within the pedagogical, teaching, social, or health profession [114]). Such solutions to providing EBPSs are particularly needed in LMICs where there may not be a readily available professional workforce who can provide EBPSs. Regardless of setting, it is important to ensure training of the workforce to ensure program fidelity, so that outcomes for children and parents are realised.

Improving the Reach and Impact of EBPSs: Two Examples of Supportive Policies

There are several times where research outcomes have been used to guide policy decisions to increase the reach of EBPSs. For example, in 2015 the Queensland Government funded the state-wide implementation of the full 5-level Triple P system, free of charge for all parents of children from birth to age 16 [115]. This policy-based investment came about because the government was convinced by the strength of available evidence that the programs comprising each level would benefit children and families. Approximately 400,000 parents have reported participating in the program.

The Communities That Care (CTC; [116]) approach is another example of how policies can be used to support the selection and use of EBPSs to address population-wide problems. In the CTC approach training is provided to local government coalitions to complete epidemiologically valid surveys with children and young people. These survey results are then used to prioritise family risk and protective factors to be measurably enhanced through EBPSs. The CTC process has assisted coalitions of local government areas to increase their investment in evidence-based family and community programs [116], with flow-on benefits such as reducing child hospital injury admissions across large municipalities [117]. Thus, we believe that it is possible and prudent for policymakers to use research outcomes to guide policy decisions to increase the reach of EBPSs, and subsequently improve the wellbeing of families concurrently and in the future.

Summary

The majority of mental health problems have their origins in childhood and adolescence, and it is well documented that investing in the mental health of future generations has long-term benefits for all aspects of society [42, 43]. EBPSs can successfully create conditions for change for parents and children across a range of outcomes, including child and adolescent mental health, physical health, competencies, and academic outcomes; parental skills, competencies, wellbeing and mental health; and prevention of child maltreatment and family violence. Thus, EBPSs provide an effective means to address several high priority mental health, physical health, and social problems. Yet few policies adequately support the use of EBPSs as mechanisms to support parents and children, and address these high priority problems. We have identified that policy makers need to (a) ensure that they are funding multiple non-stigmatising “soft-entry” points into a variety of EBPSs for parents/caregivers at the population-level; (b) address funding barriers so that parents/caregivers are able to access EBPSs; (c) ensure that funding for EBPSs is transparent and promotes accountability; (d) fund research examining for whom, in what context, and in what combination, different EBPSs work. Further, to ensure workforce readiness, professional associations that develop guidelines for university-based training should add guidelines to ensure the inclusion of systematic skills-based training in at least one EBPS model. It is vital that research efforts and policies continue to create more favourable community conditions that support competent parenting, so that the reach of EBPSs can become population-wide and socially normative.
