A qualitative evaluation of the mechanisms of action in an early childhood parenting programme to prevent violence against children in Jamaica.

BACKGROUND: Violence against children (VAC) is a global public health problem, and parenting programmes are a key strategy to reduce VAC at home. We developed and evaluated a preschool-based, early childhood, violence prevention, parenting programme (the Irie Homes Toolbox) in Jamaica and reported significant reductions in parents' use of VAC [Effect size (ES) = -0.29] and increases in parents' positive practices (ES = 0.30). This study presents qualitative findings on the mechanisms of action of the programme. METHODS: As part of a cluster randomized trial, 115 parents from nine preschools participated in the Irie Homes Toolbox parenting programme. The programme consisted of eight 90-min sessions with groups of six parents and focussed on strengthening parent-child relationships, understanding children's behaviour, using appropriate discipline strategies and understanding and managing emotions. We conducted in-depth, semi-structured interviews with a stratified random sample of 28 parents (two to four parents per school) and with nine preschool teachers (one teacher per preschool). Topic guides were developed to explore participants' perspectives of the mechanisms of action of the programme. All interviews were audio-recorded and transcribed, and data were analysed using the framework approach. RESULTS: The most salient direct pathways to reduced VAC by both parent and teacher reports were through parents' use of alternative strategies to manage child misbehaviour and through improved parent well-being, especially parents' self-management skills. Other factors leading to reduced VAC by parents, reported by both parents and teachers, included self-identification as an 'Irie parent', use of proactive parenting strategies and improved child behaviour. Parents reported that the main factors leading to continued use of VAC were their inconsistency in using positive discipline strategies and poor emotional self-regulation. CONCLUSION: Reports from participating parents and preschool teachers indicate that contents related to parental self-management and how to use positive discipline strategies to manage child misbehaviour were important factors on the pathway to reduced VAC.

Scaling-up an early childhood parenting intervention by integrating into government health care services in rural Bangladesh: A cluster-randomised controlled trial.

AIMS: We evaluated the feasibility and effectiveness of utilising government health supervisors to train and supervise primary health care workers (HWs) in community clinics to deliver parenting sessions as part of their usual duties. METHODS: We randomly allocated 16 unions in the Mymensing district of Bangladesh 1:1 to an intervention or control group. HWs in clinics in the eight intervention unions (n = 59 health workers, n = 24 clinics) were trained to deliver a group-based parenting intervention, with training and supervision provided by government supervisors. In each of the 24 intervention clinics, we recruited 24 mothers of children aged 6-24 months to participate in the parenting sessions (n = 576 mother/child dyads). Mother/child dyads attended fortnightly parenting sessions at the clinic in groups of four to five participants for 6 months (13 sessions). We collected data on supervisor and HW compliance in implementing the intervention, mothers' attendance and the observed quality of parenting sessions in all intervention clinics and HW burnout at endline in all clinics. We randomly selected 32 clinics (16 intervention, 16 control) and 384 mothers (192 intervention, 192 control) to participate in the evaluation on mother-reported home stimulation, measured at baseline and endline. RESULTS: Supervisors and HWs attended all training, 46/59 health workers (78%) conducted the majority of parenting sessions, (only two HWs [3.4%] refused) and mothers' attendance rate was 86%. However, supervision levels were low: only 32/57 (56.1%) of HWs received at least one supervisory visit. Intervention HWs delivered the parenting sessions with acceptable levels of quality on most items. The intervention significantly benefitted home stimulation (effect size = 0.53SD, 95% confidence interval: 0.50, 0.56, p < 0.001). HW burnout was low in both groups. CONCLUSION: Integration into the primary health care service is a promising approach for scaling early childhood development programmes in Bangladesh, although further research is required to identify feasible methods for facilitator supervision.

Qualitative evaluation of a scalable early childhood parenting programme in rural Colombia.

BACKGROUND: Integrating early childhood parenting programmes into existing government services is a key strategy for reducing the loss of children's developmental potential in low- and middle-income countries. There is limited evidence of participants' perceptions of these programmes, especially when implemented at scale. We integrated an intervention into an existing government programme targeting pregnant women and mothers of children up to 2 years of age and their families in rural Colombia. METHODS: As part of a cluster randomized trial, 171 government workers (facilitators) implemented the intervention. The intervention included four components: (1) structured curricula, (2) play materials, (3) nutrition and (4) training and supervision. In this qualitative evaluation of the programme, we conducted semi-structured interviews with beneficiary mothers (n = 62), facilitators (n = 40) and supervisors (n = 8). Topic guides were developed to collect information on participants' perspectives of the acceptability, feasibility and effectiveness of the intervention and the enablers and barriers to implementation. All interviews were audiotaped and transcribed, and data were analysed using the framework approach. RESULTS: Participants' responses indicated that the intervention was acceptable, feasible and effective. Key enablers to implementation were (1) the use of evidence-based behaviour change techniques leading to interactive, fun and participatory sessions; (2) structured curricula with easy to use, simple activities and materials; (3) the focus on positive, supportive relationships; and (4) the perceived benefits of the programme to the beneficiary mothers, children and families, facilitators and programme supervisors. The main barriers were (1) facilitators took time to become comfortable and competent in using the new participatory methodology and (2) the logistics related to making and distributing the play materials. CONCLUSION: Providing structured curricula and play materials with training and ongoing supervision to enhance an existing programme targeting mothers, families and children was reported as acceptable, feasible and effective by beneficiary mothers and programme staff.

The Process of Scaling Early Childhood Violence Prevention Programs in Jamaica.

BACKGROUND: Violence is a global public health problem, and early childhood interventions are a core component of violence prevention programming. Interventions to support parents and teachers of young children can prevent violence against children by caregivers and prevent the early development of antisocial behavior. However, there is limited guidance on how to scale up these programs in low- and middle-income countries. METHODS: In this article, we describe how we applied implementation science principles in the design, implementation, evaluation, and initial scaling of 2 complementary early childhood, violence prevention, caregiver training programs in Jamaica: the Irie Classroom Toolbox (a teacher-training program) and the Irie Homes Toolbox (a parenting program). RESULTS: We identified 7 implementation science principles most relevant to our work in scaling the Irie Toolbox programs and describe how these principles were operationalized in the Jamaican context. The principles are: (1) design programs for scale from the outset; (2) use learning cycles for quality improvement; (3) plan strategically for government agency adoption; (4) provide high-quality initial and ongoing training and regular supervision; (5) monitor implementation quality; (6) use flexible delivery modes; and (7) plan for program sustainment. CONCLUSIONS: Through applying these principles to scale the Irie Toolbox programs, we aim to promote a consistent approach to reducing violence against children, reducing child behavior problems, and increasing caregiver and child competencies across both home and school contexts at the population level. The principles and processes described in this article are relevant to other behavior change interventions in early childhood development, education, and public health.

Implementation Quality of an Early Childhood Parenting Program in Colombia and Child Development.

OBJECTIVES: We conducted a cluster-randomized trial of an enhancement to an existing parenting program in rural Colombia (called the Family, Women, and Infancy Program [FAMI]), and found benefits to parenting practices and child development. In this study, we examine the effects of the enhancement on the quality of intervention implementation and examine associations between quality and child and maternal outcomes. METHODS: In Colombia, 340 FAMI mothers in 87 towns were randomly assigned to quality enhancement through the provision of structured curricula, play materials, and training and supervision from professional tutors, or to control (no enhancement). Children aged <12 months were enrolled (N = 1460). A subsample of 150 FAMI mothers (83 intervention, 67 control) in 29 towns (17 intervention, 12 control) participated in the assessment of the quality of group parenting sessions through independent observation. Child development and parenting practices were measured at endline (10.5 months after baseline). RESULTS: In intention-to-treat analyses, we found significant benefits of intervention for the observed quality of group sessions (1.67 SD [95% confidence interval, 1.23-2.11]). An SD increase in session quality predicted an increase in treatment mothers' attendance of 4.68 sessions (95% confidence interval, 1.37-7.98). Session quality partially mediated the effect of the intervention on parental practices and child development. CONCLUSIONS: Enhancing an existing parenting program led to large benefits to the observed quality of intervention implementation. Quality was associated with increased maternal engagement, parenting practices, and child development. The observational measure of quality has potential to promote and maintain quality at scale.

Using lessons learnt from key stakeholders to increase support for scaling the Reach Up Early Childhood Parenting program.

Introduction: Sustainable implementation of early childhood programs requires resources, materials and methods that are adaptable, scalable and feasible for delivery through multiple sectors. Additional or modified program resources may be required to meet emerging needs, as programs go to scale. An active and effective monitoring, evaluation and learning (MEL) process may enable programs to be responsive to demands. The Reach Up: Early Childhood Parenting program, is designed primarily for disadvantaged children under 4 years of age in low- and middle-income countries (LMICs) to promote their development through playful caregiver interactions. The curriculum, training manuals and other materials and resources support implementers in the adaptation of the intervention, implementation, workforce training, monitoring and evaluation. This paper reports on how data collected from key informants drove modifications to program processes, materials and resources. Methods: We conducted in-depth interviews with 14 key informants (including program managers, lead trainers, academics, consultants and workforce personnel) on their experiences with Reach Up across 15 LMICs where the program has been implemented. We also reviewed written records generated from (i) structured small group discussions at a Knowledge Exchange meeting of 31 Reach Up partners and (ii) notes from working groups formed at the meeting and tasked to continue working post-meeting to find solutions to support ongoing implementation. The transcripts from the in-depth interviews and the meeting records were analysed using thematic analysis with a mixture of pre-defined categories and data-driven sub-themes. Results: The main findings indicated that there was a need to: (i) develop advocacy and communication resources and materials to aid prospective implementers and other stakeholders, to make decisions for implementation, (ii) revise and/or add to the content and format of the curriculum and add content in the training and other supporting manuals and (iii) enhance the training process. Conclusion: The feedback from the key global partners informed the development of new knowledge materials, resources and processes and modifications to existing program materials and resources. These will help to support advocacy, ongoing implementations, and the process of transitioning the Reach Up early childhood intervention to scale.

The Reach Up Parenting Program, Child Development, and Maternal Depression: A Meta-analysis.

BACKGROUND AND OBJECTIVES: Evidence is needed on effective approaches to build parents' ability to promote child development feasible in low- and middle-income countries. Our objective was to synthesize impact of the Reach Up early childhood parenting program in several low- and middle-income countries and examine moderation by family and implementation characteristics. METHODS: Systematic search using PubMed and Academic Search Elite/EBSCO Host. Randomized controlled trials of the Reach Up program from 1985 to February 2022 were selected. Data were extracted by 2 independent researchers. Primary outcomes were child cognitive, language, and motor development. Secondary outcomes were home stimulation and maternal depressive symptoms. We synthesized pooled effect sizes using random effect inverse-variance weighting and effect modification by testing pooled subgroup effect estimates using the χ2 test for heterogeneity. RESULTS: Average effect size across 18 studies ranged from 0.49 (95% confidence interval [CI] 0.32 to 0.66) for cognition, 0.38 (CI 0.24 to 0.51) for language, 0.27 (CI 0.13 to 0.40) for motor development, 0.37 (CI 0.21 to 0.54) for home stimulation, and -0.09 (CI -0.19 to 0.01) for maternal depressive symptoms. Impacts were larger in studies targeted to undernourished children, with mean enrollment older than age 12 months and intervention duration 6 to 12 months. Quality of evidence assessed with the Cochrane Assessment of Risk of Bias and GRADE system was moderate. Instruments used to assess child development varied. In moderator analyses, some subgroups included few studies. CONCLUSIONS: Reach Up benefits child development and home stimulation and is adaptable across cultures and delivery methods. Child and implementation characteristics modified the effects, with implications for scaling.

Child and adolescent mental health worldwide: evidence for action.

Mental health problems affect 10-20% of children and adolescents worldwide. Despite their relevance as a leading cause of health-related disability in this age group and their longlasting effects throughout life, the mental health needs of children and adolescents are neglected, especially in low-income and middle-income countries. In this report we review the evidence and the gaps in the published work in terms of prevalence, risk and protective factors, and interventions to prevent and treat childhood and adolescent mental health problems. We also discuss barriers to, and approaches for, the implementation of such strategies in low-resource settings. Action is imperative to reduce the burden of mental health problems in future generations and to allow for the full development of vulnerable children and adolescents worldwide.

Inequality in early childhood: risk and protective factors for early child development.

Inequality between and within populations has origins in adverse early experiences. Developmental neuroscience shows how early biological and psychosocial experiences affect brain development. We previously identified inadequate cognitive stimulation, stunting, iodine deficiency, and iron-deficiency anaemia as key risks that prevent millions of young children from attaining their developmental potential. Recent research emphasises the importance of these risks, strengthens the evidence for other risk factors including intrauterine growth restriction, malaria, lead exposure, HIV infection, maternal depression, institutionalisation, and exposure to societal violence, and identifies protective factors such as breastfeeding and maternal education. Evidence on risks resulting from prenatal maternal nutrition, maternal stress, and families affected with HIV is emerging. Interventions are urgently needed to reduce children's risk exposure and to promote development in affected children. Our goal is to provide information to help the setting of priorities for early child development programmes and policies to benefit the world's poorest children and reduce persistent inequalities.

Reducing child conduct problems and promoting social skills in a middle-income country: cluster randomised controlled trial.

BACKGROUND: There is an urgent need for effective, affordable interventions to prevent child mental health problems in low- and middle-income countries. AIMS: To determine the effects of a universal pre-school-based intervention on child conduct problems and social skills at school and at home. METHOD: In a cluster randomised design, 24 community pre-schools in inner-city areas of Kingston, Jamaica, were randomly assigned to receive the Incredible Years Teacher Training intervention (n = 12) or to a control group (n = 12). Three children from each class with the highest levels of teacher-reported conduct problems were selected for evaluation, giving 225 children aged 3-6 years. The primary outcome was observed child behaviour at school. Secondary outcomes were child behaviour by parent and teacher report, child attendance and parents' attitude to school. The study is registered as ISRCTN35476268. RESULTS: Children in intervention schools showed significantly reduced conduct problems (effect size (ES) = 0.42) and increased friendship skills (ES = 0.74) through observation, significant reductions to teacher-reported (ES = 0.47) and parent-reported (ES = 0.22) behaviour difficulties and increases in teacher-reported social skills (ES = 0.59) and child attendance (ES = 0.30). Benefits to parents' attitude to school were not significant. CONCLUSIONS: A low-cost, school-based intervention in a middle-income country substantially reduces child conduct problems and increases child social skills at home and at school.

The Irie Classroom Toolbox: Mixed method assessment to inform future implementation and scale-up of an early childhood, teacher-training, violence-prevention programme.

Introduction: Violence against children (VAC) is a violation of child rights, has high prevalence in low- and middle-income countries, is associated with long-term negative effects on child functioning, and with high economic and social costs. Ending VAC at home and at school is thus a global public health priority. Methods: In Jamaica, we evaluated an early childhood, teacher-training, violence-prevention programme, (the Irie Classroom Toolbox), in a cluster-randomised trial in 76 preschools. The programme led to large reductions to teachers' use of VAC, although the majority of teachers continued to use VAC at times. In this paper, we describe a mixed-method evaluation of the Irie Classroom Toolbox in the 38 Jamaican preschools that were assigned to the wait-list control group of the trial. In a quantitative evaluation, 108 preschool teachers in 38 preschools were evaluated at pre-test and 91 teachers from 37 preschools were evaluated at post-test. One preschool teacher from each of these 37 preschools were randomly selected to participate in an in-depth interview as part of the qualitative evaluation. Results: Preschool teachers were observed to use 83% fewer instances of VAC across one school day after participating in the programme, although 68% were observed to use VAC at least once across two days. The qualitative evaluation confirmed these findings with all teachers reporting reduced use of violence, but 70% reporting continued use of VAC at times. Teachers reported that the behaviour change techniques used to deliver the intervention increased their motivation, knowledge and skills which in turn led to improved child behaviour, improved relationships and improved professional well-being. Direct pathways to reduced use of VAC by teachers were through improved child behaviour and teacher well-being. The main reasons for continued use of VAC were due to barriers teachers faced using positive discipline techniques, teachers' negative affect, and child behaviours that teachers perceived to be severe. Discussion: We describe how we used the results from the mixed-method evaluation to inform revisions to the programme to further reduce teachers' use of VAC and to inform the processes of training, supervision and ongoing monitoring as the programme is scaled-up through government services.

The Apapacho Violence Prevention Parenting Program: Conceptual Foundations and Pathways to Scale.

Violence against children (VAC) is a major global issue with long-lasting negative consequences on individuals and societies. The present study presents a review of the literature on drivers of VAC and the core components of evidence-based violence prevention programs. Moreover, it analyzes the existing services and social infrastructure in Colombia to rigorously inform the design of the Apapacho violence prevention parenting program for families with children younger than five targeted toward Colombia. Findings indicate that (1) VAC in Colombia is a multidimensional issue with roots at the individual, family, community, and society levels, (2) evidence-based violence prevention programs share a common set of content and delivery strategies that could inform the components of the Apapacho program, and (3) there is an urgent need for scalable and flexible violence prevention programs for families with young children in Colombia. Considering existing evidence, the Apapacho violence prevention parenting program will be designed using ecological, developmental, and neuroscience-informed perspectives. This article concludes by presenting the initial components of the theory of change and discussing future directions for the design of the Apapacho program and other violence prevention interventions in LMICs.

Early Stimulation and Nutrition: The Impacts of a Scalable Intervention.

Early childhood development is becoming the focus of policy worldwide. However, the evidence on the effectiveness of scalable models is scant, particularly when it comes to infants in developing countries. In this paper, we describe and evaluate with a cluster-Randomized Controlled Trial an intervention designed to improve the quality of child stimulation within the context of an existing parenting program in Colombia, known as FAMI. The intervention improved children's development by 0.16 of a standard deviation (SD) and children's nutritional status, as reflected in a reduction of 5.8 percentage points of children whose height-for-age is below -1 SD.

Integrating a Group-Based, Early Childhood Parenting Intervention Into Primary Health Care Services in Rural Bangladesh: A Cluster-Randomized Controlled Trial.

Background: Over 250 million children globally do not reach their developmental potential. We tested whether integrating a group-based, early childhood parenting program into government healthcare clinics improved children's development, growth, and behavior. Methods: We conducted a cluster-randomized controlled trial in 40 community clinics in the Kishorganj district of Bangladesh. We randomly assigned clinics (1:1) to deliver a group-based parenting interventions or to a comparison group that received no intervention. Participants were children aged 5-24 months, with weight-for-age z-score of ≤ -1.5 SDs of the WHO standards, living within a thirty-minute walking distance from the clinic (n = 419 intervention, 366 control). Government health staff facilitated parenting sessions in the clinic with groups of four mother/child dyads fortnightly for one year as part of their routine duties. Primary outcomes measured at baseline and endline were child development assessed using the Bayley scales, child behaviors during the test by tester ratings, and child growth. The trial is registered at ClinicalTrials.gov, NCT02208531. Findings: 91% of children were tested at endline (396 intervention, 319 control). Multilevel analyses showed significant benefits of intervention to child cognition (effect size 0.85 SDs, 95% CI: 0.59, 1.11), language (0.69 SDs, 0.43, 0.94), and motor development (0.52 SDs, 0.31, 0.73), and to child behaviors during the test (ranging from 0.36 SDs, 0.14, 0.58, to 0.53 SDs, 0.35, 0.71). There were no significant effects on growth. Conclusion: A scalable parenting intervention, integrated into existing government health services and implemented by government health staff, led to significant benefits to child development and behavior.

Effects of a Teacher-Training Violence Prevention Program in Jamaican Preschools on Child Behavior, Academic Achievement, and School Attendance in Grade One of Primary School: Follow up of a Cluster Randomized Trial.

Objective: We evaluated the effect of a universal, teacher-training, violence-prevention program implemented in preschool, on high-risk children's behavior, achievement, and attendance in grade one of primary school. Methods: A cluster-randomized trial was conducted in 24 preschools in Kingston, Jamaica. Three children from each class with the highest level of teacher-reported conduct problems were recruited for evaluation of outcomes (n = 225 children). For this study, to increase power, we recruited an additional two children from each class with the next highest teacher-reported scores for conduct problems in preschool. In the final term of grade one of primary school, we assessed children's: (1) conduct problems and social skills at home and school, (2) academic achievement, language, and self-regulation skills, and (3) school attendance. Results: 214/225 (95.1%) of the children evaluated in preschool were assessed in grade one of primary school; an additional 150 children were recruited to give 364 children (181 intervention, 183 control). Significant benefits of intervention were found for child academic achievement (Effect size (ES) = 0.23, p = 0.02), oral language (ES = 0.28, p = 0.006), self-regulation (ES = 0.25, p = 0.007), and school attendance (ES = 0.30, p = 0.003). No significant benefits were found for observed conduct problems (ES = -0.13, p = 0.16), and parent-reported conduct problems (ES = 0.10, p = 0.31) and social skills (ES = -0.07, p = 0.52). Benefits to teacher-reported conduct problems and social skills were significant at p < 0.1 (ES = -0.16, p = 0.09, and ES = 0.19, p = 0.06, respectively). Conclusion: A scalable intervention involving training preschool teachers in classroom behavior management and how to promote child social-emotional competence led to positive outcomes in primary school across multiple child developmental domains for high-risk children.

The Irie Classroom Toolbox, a universal violence-prevention teacher-training programme, in Jamaican preschools: a single-blind, cluster-randomised controlled trial.

BACKGROUND: Violence is a leading global public health problem, and interventions in early childhood are important in the primary prevention of violence. We tested whether the Irie Classroom Toolbox, a violence-prevention teacher-training programme reduced violence against children by teachers and reduced class-wide child aggression in Jamaican preschools (catering to children aged 3-6 years). METHODS: We did a single-blind, cluster-randomised controlled trial in 76 preschools in Kingston and St Andrew, randomly selected, using simple randomisation, from 120 eligible preschools. Inclusion criteria were two to four classes of children; at least ten children per class; and located in an urban area. We randomly assigned preschools (1:1) to either the Irie Classroom Toolbox intervention or waiting-list control that received no intervention, using a computer-generated randomisation sequence by an independent statistician masked to school identity. The Toolbox involved training teachers in classroom behaviour management and promoting child social-emotional competence. All assessors were masked to group assignment. All teachers and classrooms in the selected schools participated in the study. Within each school, we used simple randomisation to randomly select up to 12 children aged 4 years for evaluation of child outcomes. The Toolbox intervention was implemented from August to April the following year. Teacher and classroom measures were done at baseline (the summer school term; ie, May to June), post-intervention (after 8 months of intervention; ie, May to June of the following year), and 1-year follow-up (ie, May to June 2 years later). The primary outcomes were observations of violence against children (including physical violence and psychological aggression) by teachers occurring across one full school day, and class-wide child aggression occurring over five 20-min intervals on another school day, all measured at post-intervention and 1-year follow-up and analysed by intention to treat. This trial is registered with ISRCTN, number ISRCTN11968472. FINDINGS: Between June 22, 2015, and April 29, 2016, (after baseline measurements were completed), we assigned 38 preschools (with 119 teachers) to the Toolbox intervention and 38 preschools (with 110 teachers) to control. 441 children in the intervention schools and 424 in the control schools were included in the evaluation. All schools were included in the post-intervention and follow-up analyses. There were fewer counts of violence against children by teachers in the intervention schools compared with control schools at post-intervention (median counts 3 [IQR 0-11] vs 15 [3-35]; effect size -67·12%, 95% CI -80·71 to -53·52, p<0·0001) and 1-year follow-up (median counts 3 [IQR 0-9] vs 6 [1-16]; effect size -53·86, 95% CI -71·08 to -36·65, p<0·0001). No differences between groups were found for class-wide child aggression at post-intervention (effect size 0·07, 95% CI -0·16 to 0·29, p=0·72) or 1-year follow-up (-0·14, -0·42 to 0·16, p=0·72). INTERPRETATION: In Jamaican preschools, the Irie Classroom Toolbox effectively reduced violence against children by teachers. The Toolbox was designed for use with undertrained teachers working in low-resource settings and should be effective with early childhood practitioners in other LMICs. Additional research is needed to further develop the Toolbox to reduce class-wide child aggression.

Validity and reliability of mothers' reports of language development in 1-year-old children in a large-scale survey in Bangladesh.

BACKGROUND: In developing countries, it is often important to have measures of development in children under 3 years of age in large-scale surveys or evaluations of nutrition and stimulation programs. However, there is a lack of suitable instruments with established validity. OBJECTIVE: To develop a language test for children aged 12 to 18 months based on mothers' report, suitable for use in large-scale surveys, and examine its concurrent and predictive validity. To determine whether the test is sensitive to home stimulation and nutritional status and compare the test with the Bayley Scales of Infant Development (BSID). METHODS: A subsample of participants in a large, prospective cohort study in rural Bangladesh (MINIMat) was selected for a study of child development (n = 2,852). A total of 2,418 participants were interviewed concerning their children's expressive and receptive vocabulary, and children were tested using the BSID. RESULTS: The language test had reasonable short- and long-term reliability between 12 and 18 months (r = 0.50) and concurrent validity with the Bayley Mental Development Index (MDI) (r = 0.32 language comprehension to 0.41 language expression). Its predictive validity with IQ at age 5 years was similar to that of the Bayley MDI (r = 0.37 to 0.41 for language and r = 0.37 for MDI). Child language was independently associated with postnatal growth, stimulation in the home, gestational age, and socioeconomic status, and a similar set of variables predicted the Bayley MDI. CONCLUSIONS: The language test was reliable, had acceptable concurrent and predictive validity, and was sensitive to environmental and child characteristics. Mothers' reports of language could be useful in large-scale programs.

Design and Implementation of the Irie Homes Toolbox: A Violence Prevention, Early Childhood, Parenting Program.

This paper describes the development of the Irie Homes Toolbox, a violence prevention program targeting parents of children aged two to six years. The intervention was designed to complement an existing, teacher-training, violence prevention program, the Irie Classroom Toolbox, thus promoting an integrated approach across home and school settings. The Irie Homes Toolbox was developed through a four-stage process by integrating data from theory, formative research, and practice to ensure the intervention is acceptable, feasible, relevant, and effective in the context. The perspectives of Jamaican preschool teachers and parents of preschool children, who are the end users, were integrated into the design of the intervention throughout the development process. Stage one involved integrating theory and formative research to inform the initial intervention design. Stages two and three involved iterative cycles of design, implementation and evaluation of the intervention content, process of delivery, structure and materials. Stage four involved a further cycle of learning through a process evaluation conducted as part of a cluster-randomized controlled trial. Data from each of these four stages was used to inform the design and ongoing revisions of the toolbox with the aim of developing a low-cost, scalable and sustainable intervention for the Jamaican context. The resulting program is theory-informed and uses empirically derived content and behavior change principles operationalized for the context in which it will be delivered. The Irie Homes Toolbox is suitable for integration into the existing preschool provision in Jamaica, thus utilizing an existing service and existing staff and increasing the likelihood for wide-scale dissemination.

Adapting an Evidence-Based, Early Childhood Parenting Programme for Integration into Government Primary Health Care Services in Rural Bangladesh.

This paper describes the process of adapting an early childhood development programme, with proven effectiveness in Bangladesh, for integration into government health services in rural Bangladesh. Through a three-stage process, we adapted an evidence-based, home-visiting, programme (Reach-Up and Learn) for delivery in government health clinics by government health staff as part of their regular duties. Stage one involved preparing an initial draft of two parenting interventions for use with: (1) pairs of mother/child dyads, and (2) small groups of mother/child dyads. In stage two, we piloted the adapted interventions in nine clinics with a total of twenty-seven health staff and 357 mother/child dyads. We used data from mothers' attendance, feedback from participating mothers and health staff and observations of parenting sessions by the research team to revise the interventions. Stage three involved piloting the revised interventions in six clinics with eighteen health staff and 162 mother/child dyads. We gathered additional data on mothers' attendance and used observations by the research team to finalize the interventions. Through this three-stage process, adaptations were made to the intervention content, process of delivery, materials, and engagement strategies used. The largest challenges were related to incorporating the parenting programme into health staff's existing workload and promoting mothers' engagement in the programme. We also simplified the content and structure of the curriculum to make it easier for health staff to deliver and to ensure mothers understood the activities introduced. This iterative piloting was used prior to implementing and evaluating the interventions through an effectiveness trial.
