Parenting for Lifelong Health for Young Children in Montenegro: Preliminary Outcomes, Dissemination, and Broader Embedding of the Program.

The quality of parenting program implementation significantly affects the extent to which a program is delivered effectively as well as the likelihood of it becoming embedded in everyday services. The group based Parenting for Lifelong Health for Young Children (PLH-YC) program for parents of children aged 2-9 years was developed specifically for implementation in low- and middle-income contexts, has been tested in five randomized trials, and incorporates a number of strategies to encourage fidelity of delivery. This paper reports on the introduction of PLH-YC to Montenegro, including initial work to engage government agencies and service providers, adapt the program and, following initial evidence of effectiveness, implement strategies to promote effective delivery and embed the program. Following program adaptation and initial facilitator training, eight groups were run, supported with resources and supervision and independently evaluated. The successful pilot led to program training accreditation by national professional agencies and a series of steps to successfully further embed it into routine settings in Montenegro, including by recognizing the program in national policy documents. This led to further facilitator trainings, now numbering 97 facilitators and the certification of ten coaches and two trainers. By the end of 2023, 1278 parents, across 13 municipalities (half of all municipalities in Montenegro) and a range of service providers, have received the program. The paper describes the project phases and key fidelity components that underpinned the successful introduction and embedding of the program in Montenegro. The plan has resulted in Montenegro having its own domestic resources to continue to implement the program effectively and further plan for widespread dissemination.

Patterns of adverse childhood experiences and associations with prenatal substance use and poor infant outcomes in a multi-country cohort of mothers: a latent class analysis.

BACKGROUND: This paper enumerates and characterizes latent classes of adverse childhood experiences and investigates how they relate to prenatal substance use (i.e., smoking, alcohol, and other drugs) and poor infant outcomes (i.e., infant prematurity and low birthweight) across eight low- and middle-income countries (LMICs). METHODS: A total of 1189 mother-infant dyads from the Evidence for Better Lives Study cohort were recruited. Latent class analysis using the Bolck, Croon, and Hagenaars (BCH) 3-step method with auxiliary multilevel logistic regressions was performed. RESULTS: Three high-risk classes and one low-risk class emerged: (1) highly maltreated (7%, n = 89), (2) emotionally and physically abused with intra-familial violence exposure (13%, n = 152), (3), emotionally abused (40%, n = 474), and (4) low household dysfunction and abuse (40%, n = 474). Pairwise comparisons between classes indicate higher probabilities of prenatal drug use in the highly maltreated and emotionally abused classes compared with the low household dysfunction and abuse class. Additionally, the emotionally and physically abused with intra-familial violence exposure class had higher probability of low birthweight than the three remaining classes. CONCLUSION: Our results highlight the multifaceted nature of ACEs and underline the potential importance of exposure to childhood adversities on behaviors and outcomes in the perinatal period. This can inform the design of antenatal support to better address these challenges.

Perceived stress during the prenatal period: assessing measurement invariance of the Perceived Stress Scale (PSS-10) across cultures and birth parity.

Maternal prenatal stress places a substantial burden on mother's mental health. Expectant mothers in low- and middle-income countries (LMICs) have thus far received less attention than mothers in high-income settings. This is particularly problematic, as a range of triggers, such as exposure to traumatic events (e.g. natural disasters, previous pregnancy losses) and adverse life circumstances (e.g. poverty, community violence), put mothers at increased risk of experiencing prenatal stress. The ten-item Perceived Stress Scale (PSS-10) is a widely recognised index of subjective experience of stress that is increasingly used in LMICs. However, evidence for its measurement equivalence across settings is lacking. This study aims to assess measurement invariance of the PSS-10 across eight LMICs and across birth parity. This research was carried out as part of the Evidence for Better Lives Study (EBLS, vrc.crim.cam.ac.uk/vrcresearch/EBLS). The PSS-10 was administered to N = 1,208 expectant mothers from Ghana, Jamaica, Pakistan, the Philippines, Romania, South Africa, Sri Lanka and Vietnam during the third trimester of pregnancy. Confirmatory factor analysis suggested a good model fit of a two-factor model across all sites, with items on experiences of stress loading onto a negative factor and items on perceived coping onto a positive factor. Configural and metric, but not full or partial scalar invariance, were established across all sites. Configural, metric and full scalar invariance could be established across birth parity. On average, first-time mothers reported less stress than mothers who already had children. Our findings indicate that the PSS-10 holds utility in assessing stress across a broad range of culturally diverse settings; however, caution should be taken when comparing mean stress levels across sites.

ER Unfolded Protein Response in Liver In Vivo Is Characterized by Reduced, Not Increased, De Novo Lipogenesis and Cholesterol Synthesis Rates with Uptake of Fatty Acids from Adipose Tissue: Integrated Gene Expression, Translation Rates and Metabolic Fluxes.

The unfolded protein response in the endoplasmic reticulum (UPRER) is involved in a number of metabolic diseases. Here, we characterize UPRER-induced metabolic changes in mouse livers in vivo through metabolic labeling and mass spectrometric analysis of lipid and proteome-wide fluxes. We induced UPRER by tunicamycin administration and measured synthesis rates of proteins, fatty acids and cholesterol, as well as RNA-seq. Contrary to reports in isolated cells, hepatic de novo lipogenesis and cholesterogenesis were markedly reduced, as were mRNA levels and synthesis rates of lipogenic proteins. H&E staining showed enrichment with lipid droplets while electron microscopy revealed ER morphological changes. Interestingly, the pre-labeling of adipose tissue prior to UPRER induction resulted in the redistribution of labeled fatty acids from adipose tissue to the liver, with replacement by unlabeled glycerol in the liver acylglycerides, indicating that the liver uptake was of free fatty acids, not whole glycerolipids. The redistribution of adipose fatty acids to the liver was not explicable by altered plasma insulin, increased fatty acid levels (lipolysis) or by reduced food intake. Synthesis of most liver proteins was suppressed under UPRER conditions, with the exception of BiP, other chaperones, protein disulfide isomerases, and proteins of ribosomal biogenesis. Protein synthesis rates generally, but not always, paralleled changes in mRNA. In summary, this combined approach, linking static changes with fluxes, revealed an integrated reduction of lipid and cholesterol synthesis pathways, from gene expression to translation and metabolic flux rates, under UPRER conditions. The reduced lipogenesis does not parallel human fatty liver disease. This approach provides powerful tools to characterize metabolic processes underlying hepatic UPRER in vivo.

Prenatal attachment: using measurement invariance to test the validity of comparisons across eight culturally diverse countries.

Studies in high-income countries (HICs) have shown that variability in maternal-fetal attachment (MFA) predict important maternal health and child outcomes. However, the validity of MFA ratings in low- and middle-income countries (LMICs) remains unknown. Addressing this gap, we assessed measurement invariance to test the conceptual equivalence of the Prenatal Attachment Inventory (PAI: Muller, 1993) across eight LMICs. Our aim was to determine whether the PAI yields similar information from pregnant women across different cultural contexts. We administered the 18-item PAI to 1181 mothers in the third trimester (Mean age = 28.27 years old, SD = 5.81 years, range = 18-48 years) expecting their first infant (n = 359) or a later-born infant (n = 820) as part of a prospective birth cohort study involving eight middle-income countries: Ghana, Jamaica, Pakistan, Philippines, Romania, South Africa, Sri Lanka and Vietnam. We used Multiple Group Confirmatory Factor Analyses to assess across-site measurement invariance. A single latent factor with partial measurement invariance was found across all sites except Pakistan. Group comparisons showed that mean levels of MFA were lowest for expectant mothers in Vietnam and highest for expectant mothers in Sri Lanka. MFA was higher in first-time mothers than in mothers expecting a later-born child. The PAI yields similar information about MFA across culturally distinct middle-income countries. These findings strengthen confidence in the use of the tool across different settings; future studies should explore the use of the PAI as a screen for maternal behaviour that place children at risk.

Feasibility pilot of an adapted parenting program embedded within the Thai public health system.

BACKGROUND: This feasibility pilot of the Parenting for Lifelong Health for Young Children program in Thailand aimed to: 1) explore the feasibility of study evaluation approaches; 2) assess the feasibility of delivering an adapted program; 3) report indicative effects on child maltreatment and related outcomes; and 4) examine intervention content associated with key mechanisms of change perceived by caregivers and facilitators. METHOD: Sixty primary caregivers of children aged 2-9 years were recruited for an 8-week parenting program embedded within the local health system. Mixed-methods approaches included quantitative caregiver-report and observational data from standardized instruments, and qualitative data from individual and group interviews with caregivers and program facilitators. Analyses involved Wilcoxon signed-rank tests, paired t-tests, Friedman's ANOVA, and thematic analysis. RESULTS: Participants reported that most (65%) were grandparents or great-grandparents. Study retention and response rates were high, and enrolled caregivers attended an average of 93% of sessions. Primary outcomes showed caregiver-reported pre-post reductions in overall child maltreatment (d = - 0.58, p < 0.001), as well as reductions in physical (d = - 0.58, p < 0.001) and emotional abuse (d = - 0.40, p < 0.001). Combined caregiver report and observational assessments using the HOME Inventory showed reductions in abusive and harsh parenting (d = - 0.52, p < 0.001). Secondary outcomes demonstrated decreases in child neglect; dysfunctional parenting; poor child monitoring and supervision; parental sense of inefficacy; child behavior problems; daily report on child problem behavior; parent overall depression, anxiety, and stress; and attitudes supporting physical punishment and harsh discipline. There were increases in overall positive parenting, daily positive parenting behavior, as well as HOME Inventory assessments on parent-child relationships. Thematic analyses from interviews and focus group data identified six key program themes associated with strengthened parent-child relationships, reduced child behavior problems, improved attitudes and strategies toward discipline, and improved management of parental stress. CONCLUSIONS: This study represents one of few evaluations to test the feasibility of an evidence-based parenting program embedded within routine public health service delivery in a low- or middle-income country. Findings show preliminary effectiveness in reducing child maltreatment, improvements on 22 of 24 secondary outcomes, and perceived mechanisms of change that support quantitative findings. Prospects are promising for program scalability, pending randomized controlled trial results. TRIAL REGISTRATION: 11/01/2019, ClinicalTrials.gov, ID# NCT03539341 .

Using Longitudinal Social Network Analysis to Evaluate a Community-Wide Parenting Intervention.

Harsh parenting attitudes and behaviors negatively impact children's behavior and development, and are linked to heightened levels of violence in children. Parent training programs are effective preventive interventions, but only reach caregivers who attend them. In this study, programs were implemented alongside a community mobilization process, intended to use caregivers' social networks to disseminate new parenting skills community wide. We used social network analysis to explore whether this intervention, first, increased positive parenting, second, changed social networks of female caregivers (selection), and, third, influenced parenting behavior via connections (socialization), while controlling for psychiatric morbidity, parenting stress, alcohol misuse, and child's age. "Colored" Afrikaans-speaking female caregivers (N = 235; mean age 35.92 years) in a rural community in South Africa, with children between 1½ and 18 years old, were included in the study; two waves of data were collected (January-April 2016 and June-October 2017). We detected community-wide increases in positive parenting behavior (involvement, supervision, consistent discipline, and reduced corporal punishment). Attending at least one session of a parenting skills training program (n = 51; 21.7%) significantly predicted increases in network centrality (i.e., outdegree and indegree). Caregivers appeared to use similar parenting behavior to other caregivers they were connected to within the network, especially when those others attended a parenting skills training program. Overall, the results suggest that the information in the intervention was spread throughout the community through social interactions with program attendees and the community mobilization process. The results also illustrate the value of social network analysis for ascertaining the processes by which the intervention achieved its impact.

Strengthening a Culture of Prevention in Low- and Middle-Income Countries: Balancing Scientific Expectations and Contextual Realities.

Relevant initiatives are being implemented in low- and middle-income countries (LMICs) aimed at strengthening a culture of prevention. However, cumulative contextual factors constitute significant barriers for implementing rigorous prevention science in these contexts, as defined by guidelines from high-income countries (HICs). Specifically, disseminating a culture of prevention in LMICs can be impacted by political instability, limited health coverage, insecurity, limited rule of law, and scarcity of specialized professionals. This manuscript offers a contribution focused on strengthening a culture of prevention in LMICs. Specifically, four case studies are presented illustrating the gradual development of contrasting prevention initiatives in northern and central Mexico, Panamá, and Sub-Saharan Africa. The initiatives share the common goal of strengthening a culture of prevention in LMICs through the dissemination of efficacious parenting programs, aimed at reducing child maltreatment and improving parental and child mental health. Together, these initiatives illustrate the following: (a) the relevance of adopting a definition of culture of prevention characterized by national commitments with expected shared contributions by governments and civil society, (b) the need to carefully consider the impact of context when promoting prevention initiatives in LMICs, (c) the iterative, non-linear, and multi-faceted nature of promoting a culture of prevention in LMICs, and (d) the importance of committing to cultural competence and shared leadership with local communities for the advancement of prevention science in LMICs. Implications for expanding a culture of prevention in LMICs are discussed.

A South-to-South Cultural Adaptation of an Evidence-Based Parenting Program for Families in the Philippines.

Rates of child maltreatment are higher in low- and middle-income countries due to risk factors such as social inequities, economic adversity, and sociocultural norms. Given the evidence showing the effectiveness of parenting interventions to prevent child maltreatment, this study embarked on a cultural adaptation of an evidence-based parenting program with the eventual goal of integrating it within a nationwide conditional cash transfer program for low-income Filipino parents with children aged 2-6 years. We document the systematic adaptation of the Parenting for Lifelong Health for Young Children program that was developed and tested in South Africa, for low-resource Filipino families using the heuristic framework for the cultural adaptation of interventions. We underscore the merits of conducting a multistage top-down and bottom-up process that uses a participatory approach among cultural insiders and outsiders to develop a parenting intervention that reflects the contextual realities and cultural values of end users. The adapted program, Masayang Pamilya Para sa Batang Pilipino, is the product of a delicate and deliberate effort to balance Filipino childrearing goals and values with the scientific evidence on components of parenting interventions known to promote positive parenting and prevent child maltreatment.

Los índices de maltrato infantil son más altos en los países de ingresos medios y bajos debido a factores de riesgo, como las desigualdades sociales, las dificultades económicas y las normas socioculturales. Teniendo en cuenta los datos que demuestran la eficacia de las intervenciones en la crianza para prevenir el maltrato infantil, este estudio inició una adaptación cultural de un programa de crianza factual con el objetivo principal de integrarlo dentro de un programa de transferencia condicional de dinero en efectivo a nivel nacional para padres filipinos de bajos recursos con niños de entre dos y seis años. Documentamos la adaptación sistemática del programa "Crianza para una buena salud durante toda la vida" (Parenting for Lifelong Health, PLH) orientado a niños pequeños que se desarrolló y se probó en Sudáfrica, para familias filipinas de bajos recursos utilizado el marco heurístico para las adaptaciones culturales de las intervenciones. Subrayamos los méritos de llevar a cabo un proceso multietapa descendente y ascendente que emplea un método participativo entre personas conocedoras de las culturas y personas ajenas a ella para desarrollar una intervención en la crianza que refleje las realidades contextuales y los valores culturales de los usuarios finales. El programa adaptado, Masayang Pamilya Para sa Batang Pilipino, es el producto de un esfuerzo comprometido y deliberado de equilibrar los objetivos y los valores de la crianza de los niños filipinos con las pruebas científicas sobre los componentes de las intervenciones en la crianza que promueven la crianza positiva y previenen el maltrato infantil.

Parenting for Lifelong Health for Young Children: a randomized controlled trial of a parenting program in South Africa to prevent harsh parenting and child conduct problems.

BACKGROUND: Parenting programs suitable for delivery at scale in low-resource contexts are urgently needed. We conducted a randomized trial of Parenting for Lifelong Health (PLH) for Young Children, a low-cost 12-session program designed to increase positive parenting and reduce harsh parenting and conduct problems in children aged 2-9. METHODS: Two hundred and ninety-six caregivers, whose children showed clinical levels of conduct problems (Eyberg Child Behavior Inventory Problem Score, >15), were randomly assigned using a 1:1 ratio to intervention or control groups. At t0 , and at 4-5 months (t1 ) and 17 months (t2 ) after randomization, research assistants blind to group assignment assessed (through caregiver self-report and structured observation) 11 primary outcomes: positive parenting, harsh parenting, and child behavior; four secondary outcomes: parenting stress, caregiver depression, poor monitoring/supervision, and social support. TRIAL REGISTRATION: ClinicalTrials.gov (NCT02165371); Pan African Clinical Trial Registry (PACTR201402000755243); Violence Prevention Trials Register (http://www.preventviolence.info/Trials?ID=24). RESULTS: Caregivers attended on average 8.4 sessions. After adjustment for 30 comparisons, strongest results were as follows: at t1 , frequency of self-reported positive parenting strategies (10% higher in the intervention group, p = .003), observed positive parenting (39% higher in the intervention group, p = .003), and observed positive child behavior (11% higher in the intervention group, p = .003); at t2, both observed positive parenting and observed positive child behavior were higher in the intervention group (24%, p = .003; and 17%, p = .003, respectively). Results with p-values < .05 prior to adjustment were as follows: At t1 , the intervention group self-reported 11% fewer child problem behaviors, 20% fewer problems with implementing positive parenting strategies, and less physical and psychological discipline (28% and 14% less, respectively). There were indications that caregivers reported 20% less depression but 7% more parenting stress at t1 . Group differences were nonsignificant for observed negative child behavior, and caregiver-reported child behavior, poor monitoring or supervision, and caregiver social support. CONCLUSIONS: PLH for Young Children shows promise for increasing positive parenting and reducing harsh parenting.

Interprofessional education and practice guide No. 10: Developing, supporting and sustaining a team of facilitators in online interprofessional education.

Whilst we have seen a growth in the use of information and communication technologies to deliver interprofessional education (IPE) in the last decade, little has been written about facilitating IPE in the online environment. For the last 10 years, the Faculty of Health at Deakin University has offered a fully online IPE course that has consistently employed facilitators to guide interprofessional teams in both asynchronous and synchronous (real-time) online interprofessional learning experiences. This Interprofessional Education and Practice Guide draws on the Deakin University leadership experience in supporting teams of online IPE facilitators over the last decade, underpinned by prior research and key literature. The key lessons provided in this guide aim to assist others in developing, supporting and sustaining a team of online IPE facilitators to guide asynchronous and synchronous online interprofessional learning experiences.

Online interprofessional education facilitation: A scoping review.

INTRODUCTION: The use of online media to deliver interprofessional education (IPE) is becoming more prevalent across health professions education settings. Facilitation of IPE activities is known to be critical to the effective delivery of IPE, however, specifics about the nature of online IPE facilitation remains unclear. AIM: To explore the health professions education literature to understand the extent, range and nature of research on online IPE facilitation. METHODS: Scoping review methodology was used to guide a search of four electronic databases for relevant papers. Of the 2095 abstracts initially identified, after screening of both abstracts and full-text papers, 10 studies were selected for inclusion in this review. Following abstraction of key information from each study, a thematic analysis was undertaken. RESULTS: Three key themes emerged to describe the nature of the IPE facilitation literature: (1) types of online IPE facilitation contributions, (2) the experience of online IPE facilitation and (3) personal outcomes of online IPE facilitation. These IPE facilitation themes were particularly focused on facilitation of interprofessional student teams on an asynchronous basis. DISCUSSION: While the included studies provide some insight into the nature of online IPE facilitation, future research is needed to better understand facilitator contributions, and the facilitation experience and associated outcomes, both relating to synchronous and asynchronous online environments.

A systematic review of the South African work on the well-being of young people (2000-2016).

Burgeoning research on the well-being of young people in recent years has made it difficult to identify conceptual gaps in the literature. We conducted a review of South African research in this area to better understand the use and measurement of the construct, as well as factors associated with it. The search of multiple databases identified 28 studies published in academic journals between 2000 and 2016. Within this period, studies that referred to well-being and its related subjective components varied significantly in terms of how they defined and operationalised these constructs, resulting in a fragmented body of work. The review highlights the need for a coherent research agenda in this area given the centrality of well-being research in promoting optimal outcomes in young people. Recommendations for strengthening South African research in this area are provided.

The association between neighbourhood-level deprivation and depression: evidence from the south african national income dynamics study.

BACKGROUND: Depression contributes substantially to the burden of disease in South Africa. Little is known about how neighbourhoods affect the mental health of the people living in them. METHODS: Using nationally representative data (N=11,955) from the South African National Income Dynamics Study and the South African Indices of Multiple Deprivation (SAIMD) modelled at small-area level, this study tested associations between neighbourhood-level deprivation and depression, after controlling for individual-level covariates. RESULTS: Results showed a significant positive association between neighbourhood-level deprivation and depression using the composite SAIMD (ß = 0.31 (0.15); p=0.04) as well as the separate deprivation domains. Living environment deprivation (ß =0.53 (0.16); p=0.001) and employment deprivation (ß = 0.38 (0.13); p=0.004), respectively, were the two most salient domains in predicting this relationship. CONCLUSIONS: Findings supported the hypothesis that there is a positive association between living in a more deprived neighbourhood and depression, even after controlling for individual-level covariates. This study suggests that alleviating structural poverty could reduce the burden of depression in South Africa.

Impairment of early fracture healing by skeletal muscle trauma is restored by FK506.

BACKGROUND: Heightened local inflammation due to muscle trauma or disease is associated with impaired bone regeneration. METHODS: We hypothesized that FK506, an FDA approved immunomodulatory compound with neurotrophic and osteogenic effects, will rescue the early phase of fracture healing which is impaired by concomitant muscle trauma in male (~4 months old) Lewis rats. FK506 (1 mg/kg; i.p.) or saline was administered systemically for 14 days after an endogenously healing tibia osteotomy was created and fixed with an intermedullary pin, and the overlying tibialis anterior (TA) muscle was either left uninjured or incurred volumetric muscle loss injury (6 mm full thickness biopsy from middle third of the muscle). RESULTS: The salient observations of this study were that 1) concomitant TA muscle trauma impaired recovery of tibia mechanical properties 28 days post-injury, 2) FK506 administration rescued the recovery of tibia mechanical properties in the presence of concomitant TA muscle trauma but did not augment mechanical recovery of an isolated osteotomy (no muscle trauma), 3) T lymphocytes and macrophage presence within the traumatized musculature were heightened by trauma and attenuated by FK506 3 days post-injury, and 4) T lymphocyte but not macrophage presence within the fracture callus were attenuated by FK506 at 14 days post-injury. FK506 did not improve TA muscle isometric torque production CONCLUSION: Collectively, these findings support the administration of FK506 to ameliorate healing of fractures with severe muscle trauma comorbidity. The results suggest one potential mechanism of action is a reduction in local T lymphocytes within the injured musculoskeletal tissue, though other mechanisms to include direct osteogenic effects of FK506 require further investigation.

An exploration of teaching presence in online interprofessional education facilitation.

BACKGROUND: Although the prevalence of online asynchronous interprofessional education (IPE) has increased in the last decade, little is known about the processes of facilitation in this environment. The teaching presence element of the Community of Inquiry Framework offers an approach to analyze the contributions of online facilitators, however, to date it has only been used on a limited basis in health professions education literature. AIM: Using an exploratory case study design, we explored the types of contributions made by IPE facilitators to asynchronous interprofessional team discussions by applying the notion of teaching presence. METHODS: Using a purposeful sampling approach, we analyzed 14 facilitators' contributions to asynchronous team discussion boards in an online IPE course. We analyzed data using directed content analysis based on the key indicators of teaching presence. RESULTS: The online IPE facilitators undertook the three critical pedagogical functions identified in teaching presence: facilitating discourse, direct instruction, and instructional design and organization. While our data fitted well with a number of key activities embedded in these three functions, further modification of the teaching presence concept was needed to describe our facilitators' teaching presence. CONCLUSIONS: This study provides an initial insight into the key elements of online asynchronous IPE facilitation. Further research is required to continue to illuminate the complexity of online asynchronous IPE facilitation.

What do we know about preventing school violence? A systematic review of systematic reviews.

Many children across the world are exposed to school violence, which undermines their right to education and adversely affects their development. Studies of interventions for school violence suggest that it can be prevented. However, this evidence base is challenging to navigate. We completed a systematic review of interventions to reduce four types of school violence: (a) peer violence; (b) corporal punishment; (c) student-on-teacher violence and (d) teacher-on-student violence. Reviewers independently searched databases and journals. Included studies were published between 2005 and 2015; in English; considered school-based interventions for children and measured violence as an outcome. Many systematic reviews were found, thus we completed a systematic review of systematic reviews. Only systematic reviews on interventions for intimate partner violence (IPV) and peer aggression were found. These reviews were generally of moderate quality. Research on both types of violence was largely completed in North America. Only a handful of programmes demonstrate promise in preventing IPV. Cognitive behavioral, social-emotional and peer mentoring/mediation programmes showed promise in reducing the levels of perpetration of peer aggression. Further research needs to determine the long-term effects of interventions, potential moderators and mediators of program effects, program effects across different contexts and key intervention components.
