Evidence for investing in parenting interventions aiming to improve child health: a systematic review of economic evaluations

Parenting Interventions to Prevent and Reduce Physical Punishment: A Scoping Review

Physical punishment is the most common form of violence against children worldwide and is associated with an increased risk of long-term adverse outcomes. Interventions targeting parents/caregivers are frequently implemented to prevent and reduce the use of physical punishment. This scoping review aimed to map the existing literature on evidence-informed parenting interventions targeting physical punishment. A scoping review following the World Health Organization (WHO) Review Guide, the Joanna Briggs Institute (JBI) 2020 Guide for scoping reviews, was conducted to address the objective of this review. An academic health sciences librarian systematically searched electronic databases (EBSCO, MEDLINE, EMBASE, SCOPUS) for peer-reviewed journal articles. Two reviewers independently screened titles and abstracts, followed by a full-text review according to inclusion and exclusion criteria following the Participants, Concept, and Context framework. Eighty-one studies were included for full-text eligibility. The results suggest that most interventions examined were conducted in North America, targeted mothers and fathers, and were delivered in person. The results from this scoping review describe the state of evidence-informed parenting interventions to prevent and reduce physical punishment. This review found opportunities for future research to implement effective parenting interventions on a larger societal scale and use mixed methods approaches to evaluate parenting interventions.

Strategies to Prevent Violence Against Children in the Home: A Systematic Review of Reviews

Violence against children (VAC) in the home, or by household members, is a human rights and social problem with long-lasting consequences for individuals and society. Global policy instruments like the INSPIRE package have proposed strategies to prevent VAC, including Implementation and enforcement of laws, Norms and values, Safe environments, Parent and caregiver support, Income and economic strengthening, Response and support services, and Education and life skills. This systematic review of reviews aimed to synthesize the recent evidence base (i.e., published since 2000) for each INSPIRE strategy to reduce VAC in the home or by household members. We searched four databases using controlled vocabularies and keywords and searched for additional records in prior reviews of reviews. A total of 67 studies were included in this review, including literature reviews, meta-analyses, systematic reviews, and other types of reviews. We found extensive evidence supporting the effectiveness of parent and caregiver support interventions. However, reviews on other INSPIRE strategies were scarce. We also found a vast underrepresentation of samples from low- and- middle-income countries, children with disabilities, and families affected by forced displacement and conflict. In sum, this systematic review suggests that there are several promising strategies to prevent VAC (e.g., home visiting and parent education), but further research is necessary to strengthen the current body of evidence and effectively inform the implementation and scale-up of evidence-based interventions to protect children from violence globally.

A scoping review of costing methodologies used to assess interventions for underserved pregnant people and new parents

BACKGROUND

Lack of evidence about the long-term economic benefits of interventions targeting underserved perinatal populations can hamper decision making regarding funding. To optimize the quality of future research, we examined what methods and costs have been used to assess the value of interventions targeting pregnant people and/or new parents who have poor access to healthcare.

METHODS

We conducted a scoping review using methods described by Arksey and O'Malley. We conducted systematic searches in eight databases and web-searches for grey literature. Two researchers independently screened results to determine eligibility for inclusion. We included economic evaluations and cost analyses of interventions targeting pregnant people and/or new parents from underserved populations in twenty high income countries. We extracted and tabulated data from included publications regarding the study setting, population, intervention, study methods, types of costs included, and data sources for costs.

RESULTS

Final searches were completed in May 2024. We identified 103 eligible publications describing a range of interventions, most commonly home visiting programs (n = 19), smoking cessation interventions (n = 19), prenatal care (n = 11), perinatal mental health interventions (n = 11), and substance use treatment (n = 10), serving 36 distinct underserved populations. A quarter of the publications (n = 25) reported cost analyses only, while 77 were economic evaluations. Most publications (n = 82) considered health care costs, 45 considered other societal costs, and 14 considered only program costs. Only a third (n = 36) of the 103 included studies considered long-term costs that occurred more than one year after the birth (for interventions occurring only in pregnancy) or after the end of the intervention.

CONCLUSIONS

A broad range of interventions targeting pregnant people and/or new parents from underserved populations have the potential to reduce health inequities in their offspring. Economic evaluations of such interventions are often at risk of underestimating the long-term benefits of these interventions because they do not consider downstream societal costs. Our consolidated list of downstream and long-term costs from existing research can inform future economic analyses of interventions targeting poorly served pregnant people and new parents. Comprehensively quantifying the downstream and long-term benefits of such interventions is needed to inform decision making that will improve health equity.

Evaluation of the Centers for Disease Control and Prevention's Essentials for Parenting Toddlers and Preschoolers on parent behavioral outcomes

BACKGROUND

The Centers for Disease Control and Prevention's web-based behavioral parent training (BPT) program, Essentials for Parenting Toddlers and Preschoolers (EfP), uses a psychoeducational approach to promote positive parenting and address common parenting challenges. The purpose of this study was to assess the effects of EfP on parenting behavior and whether implementation format impacted behavioral outcomes.

METHODS

A sample of 200 parents of 2- to 4-year-old children were recruited via Internet advertising. Using a repeated single subject, multiple baseline design, parents were randomly assigned to guided navigation (GN; n = 100) or unguided navigation (UN; n = 100) study conditions. Parents were provided secure access to the EfP website and completed 18 weekly surveys. Latent growth curve modeling was used to determine intervention effectiveness on behavioral outcomes.

RESULTS

Latent growth curve modeling indicated both GN and UN study conditions significantly increased use of praise (β = 0.19, p = 0.038) and commands and consequences (β = 0.17, p < 0.001), and decreased corporal punishment use (β = -0.01, p = 0.017) and attitudes promoting corporal punishment (β = -0.01, p < 0.001) over the study period. The UN condition exhibited a significant initial decrease in time-out use that increased over time to match the GN condition.

CONCLUSIONS

This study provides evidence for the effectiveness of EfP in promoting non-violent parenting behavior and increasing positive parenting techniques. The format of EfP implementation made no difference in parenting behaviors over time. Digital BPT programs like EfP provide access to evidence-informed parenting resources and can enhance positive parenting.

Brief parenting intervention (Triple P) for families of children with eczema: a randomized controlled trial

OBJECTIVE

To evaluate the efficacy and costs of a brief, group-delivered parenting intervention for families of children with eczema.

METHODS

A randomized controlled trial design was used. Families attending the Queensland Children's Hospital and from the community (n = 257) were assessed for eligibility (child 2-10 years, diagnosed with eczema, prescribed topical corticosteroids). Families who consented to participate (N = 59) were assessed at baseline for clinician-rated eczema severity, parent-reported eczema symptom severity, and electronically-monitored topical corticosteroid adherence (primary outcomes); and parenting behavior, parents' self-efficacy and task performance when managing eczema, eczema-related child behavior problems, and child and parent quality of life (secondary outcomes). Families were randomized (1:1, unblinded) to intervention (n = 31) or care-as-usual (n = 28). The intervention comprised two, 2-hr Healthy Living Triple P group sessions (face-to-face/online) and 28 intervention families attended one/both sessions. All families were offered standardized eczema education. Families were reassessed at 4-weeks post-intervention and 6-month follow-up, with clinician-raters blinded to condition. Costs of intervention delivery were estimated.

RESULTS

Multilevel modeling across assessment timepoints showed significant intervention effects for ineffective parenting (d = .60), self-efficacy (d = .74), task performance (d = .81), and confidence with managing eczema-related child behavior (d = .63), but not disease/symptom severity, treatment adherence or quality of life. Mean cost per participating family with parenting behavior (clinically) improved was $159.

CONCLUSIONS

Healthy Living Triple P is effective in reducing ineffective parenting practices and improving parents' self-efficacy and task performance when managing children's eczema and eczema-related behavior difficulties. There was no effect on disease/symptom severity, treatment adherence, or quality of life.

Early Parenting Interactions and First-Time Mothers' Postnatal Depression and Parental Competence

Objectives: Schema Therapy, an approach that integrates cognitive-behavioural and attachment principles, helps us understand the impact of early interactions with caregivers on adult mental health. These early interactions can be assessed through Schema Therapy-informed tools; however, these tools have yet to be used with a postnatal population, which represents a period of vulnerability for new mothers. Therefore, the present study aimed to evaluate the impact of positive and negative early parenting interactions on a first-time mother's mental health and her sense of competence during the postnatal period, using recently revised and newly developed Schema Therapy-informed tools. Design: This is a cross-sectional study. Method: First-time mothers (N = 220) participated in an online survey within 12 months post-birth. Participants completed the Positive Parenting Schema Inventory (PPSI), Young Parenting Inventory-Revised (YPI-R2), Edinburgh Postnatal Depression Scale (EPDS), and Parenting Sense of Competence (PSOC) scale. The data were analysed using hierarchical multiple regression and mediational analysis. Results: Negative early interactions with mothers and fathers led to greater postnatal depressive symptomology, while positive early interactions with mothers led to fewer postnatal depressive symptoms. Mediation analyses revealed that postnatal depressive symptoms mediated early parenting interactions and participants' sense of parenting competence as a new mother. Conclusions: The protective effects of positive early interactions with caregivers can help first-time mothers' postnatal emotional adjustment and their sense of competence through diminished postnatal depressive symptoms. However, the enduring effects of negative early interactions with caregivers can contribute to a first-time mother's risk of developing postnatal depression and negatively affect her sense of parental competence.

A cost-effectiveness analysis of a universal, preventative-focused, parent and infant programme

BACKGROUND

This study assessed whether a relatively newly developed Parent and Infant (PIN) parenting support programme was cost-effective when compared to services as usual (SAU).

METHODS

The cost-effectiveness of the PIN programme versus SAU was assessed from an Irish health and social care perspective over a 24-month timeframe and within the context of a non-randomised, controlled before-and-after trial. In total, 163 parent-infant dyads were included in the study (86 intervention, 77 control). The primary outcome measure for the economic evaluation was the Parenting Sense of Competence Scale (PSOC).

RESULTS

The average cost of the PIN programme was €647 per dyad. The mean (SE) cost (including programme costs) was €7,027 (SE €1,345) compared to €4,811 (SE €593) in the control arm, generating a (non-significant) mean cost difference of €2,216 (bootstrap 95% CI -€665 to €5,096; p = 0.14). The mean incremental cost-effectiveness of the PIN service was €614 per PSOC unit gained (bootstrap 95% CI €54 to €1,481). The probability that the PIN programme was cost-effective, was 87% at a willingness-to-pay of €1,000 per one unit change in the PSOC.

CONCLUSIONS

Our findings suggest that the PIN programme was cost-effective at a relatively low willingness-to-pay threshold when compared to SAU. This study addresses a significant knowledge gap in the field of early intervention by providing important real world evidence on the implementation costs and cost-effectiveness of a universal early years parenting programme. The challenges involved in assessing the cost-effectiveness of preventative interventions for very young children and their parents are also discussed.

Economic Evaluation of Family-Focused Programs When Parents Have a Mental Health Problem: Methodological Considerations

OBJECTIVES

The nature of adverse effects of parental mental health problems and of the interventions to address them may require specific designs of economic evaluation studies. Nevertheless, methodological guidance is lacking. We aim to understand the broad spectrum of adverse effects from parental mental health problems in children and the economic consequences on an individual and societal level to navigate the design of economic evaluations in this field.

METHODS

We conducted a systematic literature search of empirical studies on children's adverse effects from parental mental illness. We clustered types of impact, identified individual and public cost consequences, and illustrated the results in an impact inventory.

RESULTS

We found a wide variety of short- and long-term (mental) health impacts, impacts on social functioning and socioeconomic implications for the children individually, and adverse effects on the societal level. Consequently, public costs can occur in various public sectors (eg, healthcare, education), and individuals may have to pay costs privately.

CONCLUSIONS

Existing evaluations in this field mostly follow standard methodological approaches (eg, cost-utility analysis using quality-adjusted life-years) and apply a short-time horizon. Our findings suggest applying a long-term time horizon (at least up to early adulthood), considering cost-consequence analysis and alternatives to health-related quality of life and quality-adjusted life-years as outcome measures, and capturing the full range of possible public and private costs.

Methods of assessing value for money of UK-based early childhood public health interventions: a systematic literature review

INTRODUCTION

Economic evaluation has an important role to play in the demonstration of value for money of early childhood public health interventions; however, concerns have been raised regarding their consistent application and relevance to commissioners. This systematic review of the literature therefore aims to collate the breadth of the existing economic evaluation evidence of these interventions and to identify the approaches adopted in the assessment of value.

SOURCE OF DATA

Recently published literature in Medline, EMBASE, EconLit, Health Management Information Consortium, Cochrane CENTRAL, Cochrane Database of Systematic Reviews, Health Technology Assessment, NHS EED and Web of Science.

AREAS OF AGREEMENT

The importance of the early childhood period on future health and well-being as well as the potential to impact health inequalities making for a strong narrative case for expenditure in early childhood public health.

AREAS OF CONTROVERSY

The most appropriate approaches to evaluating value for money of such preventative interventions relevant for UK decision-makers given the evident challenges.

GROWING POINTS

The presented review considered inconsistencies across methodological approaches used to demonstrate value for money. The results showed a mixed picture in terms of demonstrating value for money.

AREAS TIMELY FOR DEVELOPING RESEARCH

Future resource allocations decisions regarding early childhood public health interventions may benefit from consistency in the evaluative frameworks and health outcomes captured, as well as consistency in approaches to incorporating non-health costs and outcomes, incorporating equity concerns and the use of appropriate time horizons.
