Evaluating the Incredible Years Toddler Parenting Programme with parents of toddlers in disadvantaged (Flying Start) areas of Wales

A meta-analytic review of the implementation characteristics in parenting interventions to promote early child development

This review summarizes the implementation characteristics of parenting interventions to promote early child development (ECD) outcomes from birth to 3 years. We included 134 articles representing 123 parenting trials (PROSPERO record CRD42022285998). Studies were conducted across high-income (62%) and low-and-middle-income (38%) countries. The most frequently used interventions were Reach Up and Learn, Nurse Family Partnership, and Head Start. Half of the interventions were delivered as home visits. The other half used mixed settings and modalities (27%), clinic visits (12%), and community-based group sessions (11%). Due to the lack of data, we were only able to test the moderating role of a few implementation characteristics in intervention impacts on parenting and cognitive outcomes (by country income level) in the meta-analysis. None of the implementation characteristics moderated intervention impacts on cognitive or parenting outcomes in low- and middle-income or high-income countries. There is a significant need in the field of parenting interventions for ECD to consistently collect and report data on key implementation characteristics. These data are needed to advance our understanding of how parenting interventions are implemented and how implementation factors impact outcomes to help inform the scale-up of effective interventions to improve child development.

Is it feasible to nest a Trial within a Cohort Study (TwiCS) to evaluate an early years parenting programme? A Born in Bradford's Better Start study protocol

BACKGROUND

Evaluating the effectiveness of early years parenting interventions provides evidence to improve the development and wellbeing of children. This protocol paper describes a study to explore the feasibility of evaluating the Incredible Years Toddler early life intervention programme, which is offered to parents of 1-3-year-olds via the Better Start Bradford programme. The study aims to use a Trial within a Cohort Study (TwiCS) design that randomly selects individuals participating in a cohort to be offered an intervention. The TwiCS information and consent process is person-centred and aims to replicate real-world practice whereby only those who are offered the intervention are given information about the intervention. The cohort is the Born in Bradford's Better Start (BiBBS) cohort, an interventional birth cohort recruiting expectant parents in three areas of Bradford, UK. The study will assess the feasibility of TwiCS procedures, staged consent, and intervention take-up.

METHODS

We will conduct a feasibility TwiCS to test study procedures. We aim to establish the following: (1) whether TwiCS methodology can be implemented to create control and intervention arms, whilst documenting any incidences of contamination within the cohort; (2) whether satisfactory rates of intervention uptake are achieved among participants allocated to the intervention; and (3) whether satisfactory rates of retention of participants in the intervention can be achieved. A Red Amber Green (RAG) rating system has been applied to support the feasibility assessment of each objective: to be rated red (not achieved), amber (partly achieved), and green (achieved). Eligible participants in the BiBBS cohort will be individually randomised 1:1 to the intervention or control arms, with stratification by child age (1 or 2 years old at the time of randomisation) and ethnicity (White British, South Asian, or other). BiBBS researchers will seek consent from participants randomised to the intervention to pass their contact details onto Incredible Years' delivery agents.

DISCUSSION

This feasibility study will inform the utility of the TwiCs approach within an experimental birth cohort to evaluate interventions for infants, toddlers, and their families.

TRIAL REGISTRATION

The study was prospectively registered on ISRCTN (ISRCTN16150114).

Parenting and family self-sufficiency services contribute to impacts of Early Head Start for children and families

Introduction

There is evidence that two-generation early childhood programs, those that strive to support not only child development, but also optimal parenting and family wellbeing, help to foster resilience for young children and their families in the face of adversity.

Methods

Using data from a large experimental evaluation, the Early Head Start Research and Evaluation Project, this paper explores how parenting and family self-sufficiency services embedded in Early Head Start (EHS), a federally funded, nationally implemented two-generation early childhood program for low-income families lasting from pregnancy and until children are three, contribute to the impacts of the program for both the children and their families.

Results

Parenting support in any modality (home visiting, case management or parent education) contributed to program impacts on important child and family outcomes, but not parent employment. Somewhat surprisingly, family receipt of employment services did not lead to any of the impacts of the program, while education and job training services did. When EHS parents received education or job training services, it led to impacts not only on mother employment, but also on other important family and child outcomes.

Discussion

These findings validate and reinforce the two-generation approach of EHS, specifically supporting the focus on parenting and parent education and job training.

A quasi-experimental effectiveness evaluation of the 'Incredible Years Toddler' parenting programme on children's development aged 5: A study protocol

Child behavioural and mental health problems have become a public health crisis. The consequences of poor mental health in childhood have large economic costs and consequences for the individual, their families, and for society. Early intervention through parenting programmes can reduce the onset of poor mental health in childhood, hence evaluating the effectiveness of parenting programmes is critical. The 'Incredible Years Toddler' parent programme is an education and training intervention designed to enhance the social and emotional wellbeing of children aged 1-3 years. Whilst previous studies show Incredible Years Toddler to provide promising effects on child outcomes in the short term, the research samples have lacked ethnic diversity and representation from socioeconomically deprived families. This quasi-experimental study is registered on ISRCTN (ISRCTN49991769). We will investigate the effectiveness of Incredible Years Toddler being delivered in three neighbourhoods in inner city Bradford, England. These neighbourhoods contain a socially and ethnically diverse population with 84% living in the poorest decile for England and Wales. Parents with a child aged 1-3 years old who are enrolled in Born in Bradford's Better Start interventional family cohort study are eligible for this study. Intervention participants will be matched to a demographically comparable control group using propensity score matching. This study will use retrospective and prospective data from participants who attended Incredible Years groups between September 2018 and April 2024. The required minimum sample is n = 1336 (ratio 1:3) to detect a small effect (odds = 1.5, d = .20) on the Early Years Foundation Stage profile total score at age 5; a measure of early child development that is routinely collected by teachers. We will also establish whether these effects are moderated by child age at entry to intervention, programme delivery mode, socioeconomic status, and ethnicity. We will also estimate the cost of the intervention and conduct a cost-consequence analysis.

Family-based physical activity interventions and family functioning: A systematic review

Family physical activity (PA) can confer multiple health benefits, yet whether PA interventions affect general family functioning has not been appraised. The purpose of this review was to evaluate studies that have examined the effect of family PA interventions, where child PA was the focus of the intervention, on constructs of family functioning. Literature searches were concluded on January 11, 2022 using seven common databases. Eligible studies were in English, utilized a family PA intervention, and assessed a measure of family functioning as a study outcome. The initial search yielded 8413 hits, which was reduced to 20 independent PA interventions of mixed quality after screening for eligibility criteria. There was mixed evidence for whether family PA interventions affected overall family functioning; however, analyses of subdomains indicated that family cohesion is improved by PA interventions when children are in the early school years (aged 5-12). High-quality studies also showed an impact of family PA interventions on family organization. Targeted interventions at specific family subsystems (e.g., father-son, mother-daughter), characteristics (low-income, clinical populations, girls), and broad multibehavioral interventions may have the most reliable effects. Overall, the findings show that family PA interventions can promote family cohesion and organization, particularly among families with children in the early school years. Higher quality research, employing randomized trial designs and targeting specific intervention and sample characteristics (e.g., different clinical conditions, specific parent-child dyads), is recommended in order to better ascertain the effectiveness of these approaches.

Positive Parenting and Early Childhood Cognition: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

This review examines the effectiveness of positive parenting interventions aimed at improving sensitivity, responsiveness, and/or non-harsh discipline on children's early cognitive skills, in four meta-analyses addressing general mental abilities, language, executive functioning, and pre-academics. The objectives are to assess the magnitude of intervention effectiveness and identify moderators of effectiveness. We include randomized controlled trials of interventions targeting positive parenting to improve cognition in children < 6 years. Studies that include children with neurodevelopmental and/or hearing disorders were excluded. MEDLINE, PsycINFO, ERIC, and ProQuest Dissertations & Theses (October 2021) and citation chaining identified relevant records. Five reviewers completed screening/assessments, extraction, and risk of bias. Pooled analysis in Comprehensive Meta-Analysis (Version 3) used random effects modeling, with moderation via Q-statistics and meta-regression. Positive parenting interventions led to significant improvements in mental abilities (g = 0.46, N = 5746; k = 33) and language (g = 0.25, N = 6428; k = 30). Effect sizes were smaller and nonsignificant for executive functioning (g = 0.07, N = 3628; k = 14) and pre-academics (g = 0.16, N = 2365; k = 7). Robust moderators emerged for language and cognition. For cognition, studies with higher risk of bias scores yielded larger intervention effects. For language, studies with younger children had larger effect sizes. Studies mitigated selection and detection bias, though greater transparency of reporting is needed. Interventions that promote parental sensitivity, responsiveness, and non-harsh discipline improve early mental abilities and language. Studies examining executive functioning and pre-academics are needed to examine moderators of intervention effectiveness. Trial registration Systematic review PROSPERO registration. CRD42020222143.

What Works to Improve Wellbeing? A Rapid Systematic Review of 223 Interventions Evaluated with the Warwick-Edinburgh Mental Well-Being Scales

INTRODUCTION

The Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) is a commonly used scale of mental wellbeing focusing entirely on the positive aspect of mental health. It has been widely used in a broad range of clinical and research settings, including to evaluate if interventions, programmes or pilots improve wellbeing. We aimed to systematically review all interventions that used WEMWBS and evaluate which interventions are the most effective at improving wellbeing.

METHODS

Eligible populations included children and adults, with no health or age restrictions. Any intervention study was eligible if the wellbeing outcome was measured using the 7 or 14-item WEMWBS scale assessed both pre- and post-intervention. We identified eligible intervention studies using three approaches: a database search (Medline, EMBASE, CINAHL, PyschInfo and Web of Science from January 2007 to present), grey literature search, and by issuing a call for evidence. Narrative synthesis and random-effects meta-analysis of standardised mean differences in the intervention group were used to summarise intervention effects on WEMWBS score.

RESULTS

We identified 223 interventions across 209 studies, with a total of 53,834 participants across all studies. Five main themes of interventions were synthesised: psychological (n = 80); social (n = 54); arts, culture and environment (n = 29); physical health promotion (n = 18); and other (n = 28). Psychological interventions based on resilience, wellbeing or self-management techniques had the strongest effect on wellbeing. A broad range of other interventions were effective at improving mental wellbeing, including other psychological interventions such as cognitive behavioural therapy, psychoeducation and mindfulness. Medium to strong effects were also seen for person-centred support/advice (social), arts-based, parenting (social) and social prescribing interventions. However, a major limitation of the evidence was that only 75 (36%) of studies included a control group.

CONCLUSIONS

WEMWBS has been widely used to assess wellbeing across a diverse range of interventions, settings and samples. Despite substantial heterogeneity in individual intervention design, delivery and groups targeted, results indicate that a broad range of intervention types can successfully improve wellbeing. Methodological changes, such as greater use of control groups in intervention evaluation, can help future researchers and policy makers further understand what works for mental wellbeing.

Long-term effects of targeted prevention programmes for families with young children: A population-based study on parenting stress and children's negative emotionality

BACKGROUND

Many prevention programmes for families focus parental adversities and adverse childhood experiences. Effects of such programmes are often examined in clinical trials; there is less research on effects under naturalistic conditions. The aim of this study was to examine the longitudinal association between parenting stress and child's negative emotionality, its modification through targeted prevention programmes, and to investigate the effects in the general population.

METHODS

Data were taken from a sample of n = 903 families with infants (mean age: 13.3 months) who participated in a baseline study (T1) and a follow-up study (T2) 2 years later. The survey included parental self-report measurements on parenting stress and child's negative emotionality (T1 and T2 each) and targeted prevention programmes (T1 only). An autoregressive cross-lagged panel design was used to analyse the association of parenting stress and the child's negative emotionality, including use of targeted prevention programmes as moderator. We also tested if targeted prevention programmes can reduce parenting stress or child's negative emotionality using Propensity Score Matching (PSM).

RESULTS

Parenting stress at T1 affected children's negative emotionality at T2, but children's negative emotionality at T1 did not affect parenting stress at T2. When targeted prevention was included as moderator, the correlation disappeared among programme users. With PSM, there was no direct effect on parenting stress or child's negative emotionality. But a subsample of parents with high parenting stress at T1 who used targeted prevention at T1 reported less child's negative emotionality problems at T2 than parents who scored high in parenting stress but did not receive targeted prevention at T1.

CONCLUSION

Results suggest that the spillover from parenting stress to child's negative emotionality may be modified by prevention. Prevention programmes may help to build resources and have a direct positive effect on the child, especially for parents with high parenting stress.

Early Development of ADHD and ODD Symptoms from the Toddler to Preschool Years

OBJECTIVE

ADHD and ODD are commonly co-occurring, but often studied individually. This study evaluated common trajectories of these disorders and explored how they co-develop in early childhood.

METHOD

Community parents (N = 273) completed online surveys about their 2-year-old. Children's inattention, hyperactivity/impulsivity, and oppositional defiant disorder symptoms over 2 years were examined using latent class, dual trajectory, and cross-lagged analyses.

RESULTS

Most children followed low symptom trajectories. A small portion showed high, moderate, or increasing trajectories. The hyperactive/impulsive domain of ADHD showed a declining symptoms group. Children in high ODD groups were likely to be in high ADHD symptom groups; the converse was true but probabilities were lower. Hyperactive/impulsive symptoms predicted ODD symptoms across time, more than vice versa.

CONCLUSION

The study extends the small body of literature assessing early development of ADHD and ODD. Findings suggest that earlier intervention for symptoms of ADHD may mitigate risk of developing ODD.

Parent-child relationship outcomes of the Incredible Years Parents and Babies Program: A Pilot Randomized Controlled Trial

Background

A warm, sensitive, and responsive relationship to a caregiver is essential for healthy child development.

Objective

This paper examines the effects of the Incredible Years Parents and Babies (IYPB) program on the parent-child relationship at post-intervention when offered as a universal parenting intervention to parents with newborn infants.

Method

We conducted a pragmatic, two-arm, parallel pilot randomized controlled trial; 112 families with newborns were randomized to IYPB intervention (76) or usual care (36). The IYPB program is a group intervention with eight two-hour sessions. In addition to parent-reported questionnaires, we collected a six-minute-long video at post-intervention from 97 families to assess the parent-child relationship, which was then coded with the Coding Interactive Behavior system.

Results

There were no significant intervention effects on either the total score or any of the seven subscales at post-intervention when the children were around 5.5 months old. For parental sensitivity, results were significant at the 10% level, favoring the IYPB group. When examining the lowest-functioning mothers in moderator analyses, we also found no significant differences between the two groups.

Conclusion

In line with parent-report outcomes, we did not find any statistically significant differences between the IYPB program and usual care on parent-child relationship when offered as a universal intervention for a relatively well-functioning group of parents with infants in a setting with a high standard of usual care. However, there was a positive trend for the total score, parental sensitivity and reciprocity with effect sizes in the range of .41-.51. It is possible that a larger sample would have resulted in significant differences for these outcomes.

A Systematic Review Focusing on Psychotherapeutic Interventions that Impact Parental Psychopathology, Child Psychopathology and Parenting Behavior

Given the high rates of co-occurrence of psychopathology within families, it is important to identify and characterize interventions that simultaneously reduce both parent and child symptoms, and improve parenting quality. This is needed as intervention development is increasingly moving toward integrated interventions that target some combination of parent and child mental health, and parenting behavior. Even so, much remains unknown regarding which treatment components provide maximum benefit for parent symptoms, child symptoms, and parenting behavior. This systematic review identified and characterized psychotherapeutic interventions that report improvements in each of three outcomes: parent symptoms, child symptoms and parenting behavior. Fifty-six unique interventions were eligible for review, of which 25 reported improvements in all three outcomes. All 25 of these interventions directly intervened on parenting behavior, often as the sole target of the intervention. Few interventions improved all three outcomes in samples in which parents, children or both met clinical-level thresholds of psychopathology. Additional research is needed to better understand the bi-directional and transactional influences of treatment on family members, and to better inform the development of interventions for dually disordered parent-child dyads across a range of diagnostic profiles.

Parenting interventions to promote early child development in the first three years of life: A global systematic review and meta-analysis

BACKGROUND

Parents are the primary caregivers of young children. Responsive parent-child relationships and parental support for learning during the earliest years of life are crucial for promoting early child development (ECD). We conducted a global systematic review and meta-analysis to evaluate the effectiveness of parenting interventions on ECD and parenting outcomes.

METHODS AND FINDINGS

We searched MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, and Global Health Library for peer-reviewed, published articles from database inception until November 15, 2020. We included randomized controlled trials (RCTs) of parenting interventions delivered during the first 3 years of life that evaluated at least 1 ECD outcome. At least 2 reviewers independently screened, extracted data, and assessed study quality from eligible studies. ECD outcomes included cognitive, language, motor, and socioemotional development, behavior problems, and attachment. Parenting outcomes included parenting knowledge, parenting practices, parent-child interactions, and parental depressive symptoms. We calculated intervention effect sizes as the standardized mean difference (SMD) and estimated pooled effect sizes for each outcome separately using robust variance estimation meta-analytic approaches. We used random-effects meta-regression models to assess potential effect modification by country-income level, child age, intervention content, duration, delivery, setting, and study quality. This review was registered with PROSPERO (CRD42018092458 and CRD42018092461). Of the 11,920 articles identified, we included 111 articles representing 102 unique RCTs. Pooled effect sizes indicated positive benefits of parenting interventions on child cognitive development (SMD = 0.32, 95% CI [confidence interval]: 0.23, 0.40, P < 0.001), language development (SMD = 0.28, 95% CI: 0.18 to 0.37, P < 0.001), motor development (SMD = 0.24, 95% CI: 0.15 to 0.32, P < 0.001), socioemotional development (SMD = 0.19, 95% CI: 0.10 to 0.28, P < 0.001), and attachment (SMD = 0.29, 95% CI: 0.18 to 0.40, P < 0.001) and reductions in behavior problems (SMD = -0.13, 95% CI: -0.18 to -0.08, P < 0.001). Positive benefits were also found on parenting knowledge (SMD = 0.56, 95% CI: 0.33 to 0.79, P < 0.001), parenting practices (SMD = 0.33, 95% CI: 0.22 to 0.44, P < 0.001), and parent-child interactions (SMD = 0.39, 95% CI: 0.24 to 0.53, P < 0.001). However, there was no significant reduction in parental depressive symptoms (SMD = -0.07, 95% CI: -0.16 to 0.02, P = 0.08). Subgroup analyses revealed significantly greater effects on child cognitive, language, and motor development, and parenting practices in low- and middle-income countries compared to high-income countries; and significantly greater effects on child cognitive development, parenting knowledge, parenting practices, and parent-child interactions for programs that focused on responsive caregiving compared to those that did not. On the other hand, there was no clear evidence of effect modification by child age, intervention duration, delivery, setting, or study risk of bias. Study limitations include considerable unexplained heterogeneity, inadequate reporting of intervention content and implementation, and varying quality of evidence in terms of the conduct of trials and robustness of outcome measures used across studies.

CONCLUSIONS

Parenting interventions for children during the first 3 years of life are effective for improving ECD outcomes and enhancing parenting outcomes across low-, middle-, and high-income countries. Increasing implementation of effective and high-quality parenting interventions is needed globally and at scale in order to support parents and enable young children to achieve their full developmental potential.

One-year follow-up of The Incredible Years Parents and Babies Program: A pilot randomized controlled trial

Background

The foundation of a healthy life begins in pregnancy and early adversity can have detrimental long-term consequences for affected children.

Objective

This paper examines the effects of the Incredible Years Parents and Babies program (IYPB) at one-year follow-up when offered as a universal parenting intervention to parents with newborn infants.

Method

We conducted a pragmatic, two-arm, parallel pilot randomized controlled trial; 112 families with newborns were randomized to IYPB intervention (n = 76) or usual care (n = 36). The IYPB program is a group intervention with eight two-hour sessions. Follow-up outcomes collected a year after the intervention ended include parental stress, depression, well-being, reflective function, sense of competence, and child cognitive and socio-emotional development.

Results

There were no intervention effects on any of the primary or secondary parent-reported outcomes at one-year follow-up when the children were 18 months old. When examining the lowest-functioning mothers in moderator analyses, we found that mothers assigned to the IYPB group reported significantly lower scores for the interest and curiosity subscale of the parent reflective function scale than control mothers (β=-1,07 [-2.09,-0.06]).

Conclusion

We found no long-term effects of the IYPB when offered as a universal intervention for a relatively well-functioning group of parents with infants in a setting with a high standard of usual care. The intervention was developed for more vulnerable families in settings with a low level of universal care and the program may be effective for families in those circumstances.

Care-experienced cHildren and young people's Interventions to improve Mental health and wEll-being outcomes: Systematic review (CHIMES) protocol

INTRODUCTION

The mental health and well-being of children and young people who have been in care (ie, care-experienced) are a priority. There are a range of interventions aimed at addressing these outcomes, but the international evidence-base remains ambiguous. There is a paucity of methodologically robust systematic reviews of intervention effectiveness, with few considering the contextual conditions under which evaluations were conducted. This is important in understanding the potential transferability of the evidence-base across contexts. The present systematic review will adopt a complex systems perspective to synthesise evidence reporting evaluations of mental health and well-being interventions for care-experienced children and young people. It will address impact, equity, cost-effectiveness, context, implementation and acceptability. Stakeholder consultation will prioritise a programme theory, and associated intervention, that may progress to further development and evaluation in the UK.

METHODS AND ANALYSIS

We will search 16 bibliographic databases from 1990 to June 2020. Supplementary searching will include citation tracking, author recommendation, and identification of evidence clusters relevant to included evaluations. The eligible population is children and young people (aged ≤25 years) with experience of being in care. Outcomes are (1) mental, behavioural or neurodevelopmental disorders; (2) subjective well-being; (3) self-harm; suicidal ideation; suicide. Study quality will be appraised with methodologically appropriate tools. We will construct a taxonomy of programme theories and intervention types. Thematic synthesis will be used for qualitative data reporting context, implementation and acceptability. If appropriate, meta-analysis will be conducted with outcome and economic data. Convergent synthesis will be used to integrate syntheses of qualitative and quantitative data.

ETHICS AND DISSEMINATION

We have a comprehensive strategy for engagement with care-experienced children and young people, carers and social care professionals. Dissemination will include academic and non-academic publications and conference presentations. Ethical approval from Cardiff University's School of Social Sciences REC will be obtained if necessary.

Learning across the UK: a review of public health systems and policy approaches to early child development since political devolution

BACKGROUND

Giving children the best start in life is critical for their future health and wellbeing. Political devolution in the UK provides a natural experiment to explore how public health systems contribute to children's early developmental outcomes across four countries.

METHOD

A systematic literature review and input from a stakeholder group was used to develop a public health systems framework. This framework then informed analysis of public health policy approaches to early child development.

RESULTS

A total of 118 studies met the inclusion criteria. All national policies championed a 'prevention approach' to early child development. Political factors shaped divergence, with variation in national conceptualizations of child development ('preparing for life' versus 'preparing for school') and pre-school provision ('universal entitlement' or 'earned benefit'). Poverty and resourcing were identified as key system factors that influenced outcomes. Scotland and Wales have enacted distinctive legislation focusing on wider determinants. However, this is limited by the extent of devolved powers.

CONCLUSION

The systems framework clarifies policy complexity relating to early child development. The divergence of child development policies in the four countries and, particularly, the explicit recognition in Scottish and Welsh policy of wider determinants, creates scope for this topic to be a tracer area to compare UK public health systems longer term.

"Putting Meat on the Bones": Understanding the Implementation of a Community-Based Early Intervention and Prevention Programme-Contextual, Person, and Programme Influences

The adoption and effective delivery of evidence-based interventions within "real-world" community-based, primary health care service settings are of crucial importance. In this paper, we explore the successes and challenges of implementing a new complex, group-based, early parenting intervention called the Parent and Infant (PIN) programme. This study involved a systematic analysis of the processes and factors that influence the implementation of the PIN programme; the analysis was guided and informed by the Implementation Outcome Framework and the Consolidated Framework for Implementation Research. A documentary review, alongside a series of one-to-one interviews and small group discussions with a range of stakeholders (n = 44), and 7 focus groups (n = 24) were used as data sources. Factors that promoted programme adoption, acceptability, and implementation feasibility included programme characteristics and stakeholder attitudes, as well as organisational and systems factors (e.g. leadership and collaboration). Key challenges to implementation success included engagement and adoption barriers. This research provides a useful and important example of real-world, theory-driven implementation research which helped to identify interrelated processes, factors, and contexts which shape and influence the implementation of early intervention and prevention programmes, removed for blind review.

Individual Participant Data Meta-analysis: Impact of Conduct Problem Severity, Comorbid Attention-Deficit/Hyperactivity Disorder and Emotional Problems, and Maternal Depression on Parenting Program Effects

OBJECTIVE

There is concern whether established parenting programs for children's conduct problems meet the needs of families with severe and complex mental health problems. For example, many children with conduct problems show comorbid attention-deficit/hyperactivity disorder (ADHD) or emotional problems, or have parents who are depressed, but families with such complex mental health problems typically seen in real life are often underrepresented in evaluation trials. We tested whether children with more severe conduct problems, and those with more complex mental health problems, benefit less from the Incredible Years parenting program, using individual participant data meta-analysis of randomized trials in Europe.

METHOD

In 1,696 families from 13 children aged (child age 2-11 years; 37% girls; 58% low income; 30% ethnic minority; 98% mothers), we used moderator analysis within a multilevel model to test whether initial conduct problem severity, comorbid ADHD or emotional problems, and maternal depression would diminish intervention effects for children's conduct problems.

RESULTS

The Incredible Years program reduced children's conduct problems overall (Cohen's d = -0.35), but more so in children with more severe conduct problems. There was no evidence that children's comorbid ADHD and emotional problems changed the intervention benefits. Children of mothers with more depressive symptoms benefited more.

CONCLUSION

Children with more severe conduct problems derive greater, rather than lesser, benefits from a high-quality group parenting program, and comorbid ADHD and emotional problems do not reduce effects; maternal depression, rather than being linked to less child change, was associated with greater reductions in children's conduct problems.

Advancing mental health equality: a mapping review of interventions, economic evaluations and barriers and facilitators

BACKGROUND

This work aimed to identify studies of interventions seeking to address mental health inequalities, studies assessing the economic impact of such interventions and factors which act as barriers and those that can facilitate interventions to address inequalities in mental health care.

METHODS

A systematic mapping method was chosen. Studies were included if they: (1) focused on a population with: (a) mental health disorders, (b) protected or other characteristics putting them at risk of experiencing mental health inequalities; (2) addressed an intervention focused on addressing mental health inequalities; and (3) met criteria for one or more of three research questions: (i) primary research studies (any study design) or systematic reviews reporting effectiveness findings for an intervention or interventions, (ii) studies reporting economic evaluation findings, (iii) primary research studies (any study design) or systematic reviews identifying or describing, potential barriers or facilitators to interventions. A bibliographic search of MEDLINE, HMIC, ASSIA, Social Policy & Practice, Sociological Abstracts, Social Services Abstracts and PsycINFO spanned January 2008 to December 2018. Study selection was performed according to inclusion criteria. Data were extracted and tabulated to map studies and summarise published research on mental health inequalities. A visual representation of the mapping review (a mapping diagram) is included.

RESULTS

Overall, 128 studies met inclusion criteria: 115 primary studies and 13 systematic reviews. Of those, 94 looked at interventions, 6 at cost-effectiveness and 36 at barriers and facilitators. An existing taxonomy of disparities interventions was used and modified to categorise interventions by type and strategy. Most of the identified interventions focused on addressing socioeconomic factors, race disparities and age-related issues. The most frequently used intervention strategy was providing psychological support. Barriers and associated facilitators were categorised into groups including (not limited to) access to care, communication issues and financial constraints.

CONCLUSIONS

The mapping review was useful in assessing the spread of literature and identifying highly researched areas versus prominent gaps. The findings are useful for clinicians, commissioners and service providers seeking to understand strategies to support the advancement of mental health equality for different populations and could be used to inform further research and support local decision-making.

Parent and facilitator experiences of an intensive parent and infant programme delivered in routine community settings

AIM

The aims of this study were to (1) assess the initial experiences of parenthood amongst mainly disadvantaged mothers; (2) explore their views on the extent to which they felt they had benefitted (or not) from participating in a newly developed, intensive mother and baby support programme in the community; and (3) explore the perspectives of those who delivered the programme (i.e., facilitators), most of whom were Public Health Nurses (PHNs).

BACKGROUND

Positive parent-child interactions and appropriate levels of infant stimulation are essential to promoting a child's well-being and laying a foundation in the early years for positive developmental outcomes. It is important, therefore, to examine participants' experiences of community-based, family-focused, early prevention and intervention programmes.

METHODS

This study was undertaken as part of a larger evaluation of a newly developed parent and infant (PIN) programme which was delivered in two disadvantaged areas in Ireland. One-to-one interviews were conducted with both mothers (n = 22) and facilitators (n = 8) (including three PHNs) plus six focus groups with an additional sub-group of facilitators (n = 17).

FINDINGS

The collective findings suggest that mothers found the programme helpful in promoting a greater understanding of their infants' behaviour and needs, and in alleviating stress and concerns associated with motherhood. Mothers described feeling more knowledgeable about the importance of regular and appropriate infant interaction to encourage learning and development. Facilitators, specifically PHNs, also reported a greater awareness of the value of infant socioemotional development for their clinical practice and observed greater positive communication between mothers and infants.

CONCLUSION

These findings suggest that a community-based, intensive mother and baby programme can help to promote parental competence and enhance infant learning and development. Additional benefits in terms of early intervention and positive changes to public health nursing practice are also discussed.

Co-occurring change in children's conduct problems and maternal depression: Latent class individual participant data meta-analysis of the Incredible Years parenting program

Children vary in the extent to which they benefit from parenting programs for conduct problems. How does parental mental health change if children benefit less or more? We assessed whether changes in conduct problems and maternal depressive symptoms co-occur following participation in the Incredible Years parenting program. We integrated individual participant data from 10 randomized trials (N = 1280; children aged 2–10 years) and distinguished latent classes based on families' baseline and post-test conduct problems and maternal depressive symptoms, using repeated measures latent class analysis (RMLCA) and latent transition analysis (LTA). Classes differed mainly in severity of conduct problems and depression (RMLCA; 4 classes). Conduct problems reduced in all classes. Depressive symptoms did not change in most classes, except in a class of families where conduct problems and depression were particularly severe. Incredible Years led to a greater likelihood of families with particularly severe conduct problems and depression moving to a class with mild problems (LTA; 3 classes). Our findings suggest that for the majority of families, children's conduct problems reduce, but maternal depressive symptoms do not, suggesting relative independence, with the exception of families with severe depression and severe conduct problems where changes for the better do co-occur.

Equity effects of parenting interventions for child conduct problems: a pan-European individual participant data meta-analysis

BACKGROUND

Childhood conduct problems are a costly public health problem and are five times more common in socially disadvantaged groups than they are in advantaged groups. Untreated, conduct problems have a poor prognosis, with increasing gaps between socioeconomic groups, and high rates of subsequent criminality. Incredible Years is a high quality parenting programme for reducing conduct problems and is widely disseminated in Europe. Many trials have shown Incredible Years to be effective but the potential effects of parenting interventions on social inequality are unknown. Some behavioural interventions (eg, smoking cessation programmes), although beneficial overall, can widen inequality gaps. Because single trials and aggregate-level meta-analyses are ill equipped for examining differential intervention (moderator) effects, we pooled individual-level trial data to assess the effects of Incredible Years on social equity.

METHODS

We did a systematic review and individual participant data meta-analysis by searching CINAHL, Embase, Global Health, Medline, and PsycINFO, for studies published from inception to March 15, 2019. We also searched the Incredible Years website library and consulted with experts, including the European Incredible Years mentors' network. We included data from all completed randomised trials of the Incredible Years parenting intervention in Europe that included children aged 1-12 years, including unpublished trials, without restriction on publication year or outcome measures. We included prevention (selective or universal) and treatment or indicated prevention trials (for children diagnosed or above the clinical cutoff for conduct problems). We excluded trials or conditions within trials that were not randomised, included additional non-parenting material (eg, child-focused interventions), or were abbreviated, non-standard versions of the usual Incredible Years intervention of 12-14 weekly sessions. We requested individual participant data from the study authors. The primary outcome was child conduct problems, assessed using the Eyberg Child Behavior Inventory Intensity (ECBI-I) scale. Moderators were analysed using multilevel modelling with multiple imputation.

FINDINGS

Of 15 European trials of Incredible Years parenting programmes (n=1696 children), individual participant data were unavailable for one trial and one trial did not assess the primary outcome. Children were aged 2-10 years (median 5·1), 492 (30%) of 1651 children were from an ethnic minority and 931 (58%) of 1614 were from low-income families. Families who received the Incredible Years intervention reported an overall reduction in child conduct problems (13·5 points on the ECBI-I scale, 95% CI 10·9-16·1). There were no differential effects by family disadvantage (indicated by poverty, lone parenthood, teenage parenthood, household joblessness, or low education), or ethnic minority status.

INTERPRETATION

We found no evidence for differential effects by social disadvantage, suggesting that Incredible Years is unlikely to widen socioeconomic inequalities in conduct problems. Furthermore, the programme might be an important tool for reducing social disparities and improving poor long-term outcomes in disadvantaged families because follow-up studies indicate that benefits persist. Clinicians and commissioners can be reassured that the programme is similarly effective for families from different backgrounds.

The Earlier the Better? Individual Participant Data and Traditional Meta-analysis of Age Effects of Parenting Interventions

Strong arguments have been made for early intervention for child problems, stating that early is more effective than later, as the brain is more malleable, and costs are lower. However, there is scant evidence from trials to support this hypothesis, which we therefore tested in two well-powered, state-of-the-art meta-analyses with complementary strengths: (a) Individual participant data (IPD) meta-analysis of European trials of Incredible Years parenting intervention (k = 13, n = 1696; age = 2-11); (b) Larger, trial-level robust variance estimation meta-analysis of a wider range of parenting programs (k = 156, n = 13,378, M_age  = 2-10) for reducing disruptive behavior. Both analyses found no evidence that intervention earlier in childhood was more effective; programs targeted at a narrower age range were no more effective than general ones.

Research Review: Harnessing the power of individual participant data in a meta-analysis of the benefits and harms of the Incredible Years parenting program

BACKGROUND

Parenting programs aim to reduce children's conduct problems through improvement of family dynamics. To date, research on the precise benefits and possible harms of parenting programs on family well-being has been unsystematic and likely to be subject to selective outcome reporting and publication bias. Better understanding of program benefits and harms requires full disclosure by researchers of all included measures, and large enough numbers of participants to be able to detect small effects and estimate them precisely.

METHODS

We obtained individual participant data for 14 of 15 randomized controlled trials on the Incredible Years parenting program in Europe (total N = 1,799). We used multilevel modeling to estimate program effects on 13 parent-reported outcomes, including parenting practices, children's mental health, and parental mental health.

RESULTS

Parental use of praise, corporal punishment, threats, and shouting improved, while parental use of tangible rewards, monitoring, or laxness did not. Children's conduct problems and attention deficit hyperactivity disorder (ADHD) symptoms improved, while emotional problems did not. Parental mental health (depressive symptoms, self-efficacy, and stress) did not improve. There was no evidence of harmful effects.

CONCLUSIONS

The Incredible Years parenting program improves the aspects of family well-being that it is primarily designed to improve: parenting and children's conduct problems. It also improves parent-reported ADHD symptoms in children. Wider benefits are limited: the program does not improve children's emotional problems or parental mental health. There are no signs of harm on any of the target outcomes.

Could scale-up of parenting programmes improve child disruptive behaviour and reduce social inequalities? Using individual participant data meta-analysis to establish for whom programmes are effective and cost-effective

Background

Child disruptive behavioural problems are a large and costly public health problem. The Incredible Years®(IY) parenting programme has been disseminated across the UK to prevent this problem and shown to be effective in several trials. It is vital for policy to know for which families IY is most effective, to be sure that it helps reduce, rather than widen, socioeconomic inequalities. Individual trials lack power and generalisability to examine differential effects; conventional meta-analysis lacks information about within-trial variability in effects.

Objectives

To overcome these limitations by pooling individual-level data from the IY parenting trials in Europe to examine to what extent it benefits socially disadvantaged families. Secondary objectives examine (1) additional moderators of effects on child behaviour, (2) wider health benefits and potential harms and (3) costs, cost-effectiveness and potential long-term savings.

Design

Individual participant data meta-analysis of 14 randomised trials of the IY parenting intervention.

Settings

UK (eight trials), the Netherlands, Ireland, Norway, Sweden and Portugal.

Participants

Data were from 1799 families, with children aged 2–10 years (mean 5.1 years; 63% boys).

Interventions

IY Basic parenting programme.

Main outcome measures

Primary outcome was disruptive child behaviour, determined by the Eyberg Child Behavior Inventory Intensity scale (ECBI-I). Secondary outcomes included self-reported parenting practices, parenting stress, mental health, children’s attention deficit hyperactivity disorder (ADHD) and emotional symptoms.

Results

There were no differential effects of IY on disruptive behaviour in families with different levels of social/socioeconomic disadvantage or differential effects for ethnic minority families, families with different parenting styles, or for children with comorbid ADHD or emotional problems or of different ages. Some moderators were found: intervention effects were strongest in children with more severe baseline disruptive behaviour, in boys, and in children with parents who were more depressed. Wider health benefits included reduced child ADHD symptoms, greater parental use of praise, and reduced harsh and inconsistent discipline. The intervention did not improve parental depression, stress, self-efficacy or children’s emotional problems. Economic data were available for five UK and Ireland trials (maximumn = 608). The average cost per person of the IY intervention was £2414. The probability that the IY intervention is considered cost-effective is 99% at a willingness to pay of £145 per 1-point improvement on the ECBI-I. Estimated longer-term savings over 20 years range from £1000 to £8400 per child, probably offsetting the cost of the intervention.

Limitations

Limitations include a focus on one parenting programme; the need to make assumptions in harmonising data; and the fact that data addressed equalities in the effectiveness of, not access to, the intervention.

Conclusions

There is no evidence that the benefits of the IY parenting intervention are reduced in disadvantaged or minority families; benefits are greater in the most distressed families, including parents who are depressed. Thus, the intervention is unlikely to widen socioeconomic inequalities in disruptive behaviour and may have effects in narrowing inequalities due to parent depression. It was as likely to be effective for older as for younger children. It has wider benefits for ADHD and parenting and is likely to be considered to be cost-effective. Researchers/funders should encourage data sharing to test equity and other moderator questions for other interventions; further research is needed on enhancing equality of access to interventions.

Parenting and child mental health

This paper reviews parenting programmes and their effectiveness with families of young children and highlights additional resources for primary care practitioners. Typically, 30% of GP consultations concern child behaviour problems and established behaviour problems can have lasting effects on children's life chances. These problems can be identified in infancy and toddlerhood.Parenting is a key risk factor in their development and maintenance, yet is also amenable to change. In this paper we consider six parenting programmes that are widely evaluated and/or available in the U.K. and their evidence base . These include two NICE recommended parenting programmes (Incredible Years and Triple P), which offer tiered and flexible parenting programmes; predominantly for parents of school-age children. We also review Parent-Infant Psychotherapy, which is typically for parents of younger children. Fourth is Family Nurse Partnership, an intensive programme to support young, first-time mothers. Finally we consider, video feedback programmes which use video to focus in detail on parents' interactions with their children, including Video Feedback to Promote Positive Parenting and Video Interactive Guidance. These interventions demonstrate the range of approaches which are being used to intervene early in children's lives to try to prevent the development of enduring behavioural problems.

WHY THIS MATTERS TO ME

It is becoming increasingly clear that the origins of many mental health problems lie in childhood. Family factors, including the quality of care that parents provide for their children, can make a huge difference to children's early life pathways, for better or for worse. Understanding how best to intervene to support parents is a key challenge. In this article, we critically review the most widely used parenting programmes for parents of young children. It is imperative that we judge these early interventions to high standards so that we are offering children the best start in life.

KEY MESSAGE

Parenting programmes offer a means to intercept behaviour problems in early childhood before they become established.
