Innovate! Accelerate! Evaluate! Harnessing the RE-AIM framework to examine the global dissemination of parenting resources during COVID-19 to more than 210 million people

Background Parents were at the forefront of responding to the needs of children during the COVID-19 pandemic. This study used the RE-AIM framework to examine the Reach, Effectiveness, Adoption, Implementation, and Maintenance of a global inter-agency initiative that adapted evidence-based parenting programs to provide immediate support to parents. Methods Data were collected via short surveys sent via email, online surveys, and analysis of social media metrics and Google Analytics. Retrospective surveys with 1,303 parents and caregivers in 11 countries examined impacts of the resources on child maltreatment, positive relationship building, parenting efficacy, and parenting stress. Results The parenting resources were translated into over 135 languages and dialects; reached an estimated minimum 212.4 million people by June 2022; were adopted by 697 agencies, organizations, and individuals; and were included in 43 national government COVID-19 responses. Dissemination via social media had the highest reach (n = 144,202,170, 67.9%), followed by radio broadcasts (n = 32,298,525, 15.2%), text messages (n = 13,565,780, 6.4%), and caseworker phone calls or visits (n = 8,074,787, 3.8%). Retrospective surveys showed increased parental engagement and play, parenting self-efficacy, confidence in protecting children from sexual abuse, and capacity to cope with stress, as well as decreased physical and emotional abuse. Forty-four organizations who responded to follow-up surveys in April 2021 reported sustained use of the resources as part of existing services and other crisis responses. Conclusion This study highlights the importance of a) establishing an international collaboration to rapidly adapt and disseminate evidence-based content into easily accessible resources that are relevant to the needs of parents; b) creating open-source and agile delivery models that are responsive to local contexts and receptive to further adaptation; and c) using the best methods available to evaluate a rapidly deployed global emergency response in real-time. Further research is recommended to empirically establish the evidence of effectiveness and maintenance of these parenting innovations.

Background
The SARS-CoVCoV-2 (COVID-19) pandemic negatively impacted the lives of children and families globally, with increased risks for those living in low-and middle-income countries (LMICs) or marginalized communities [1].School closures affecting approximately 1.4 billion children worldwide at the height of the pandemic resulted in substantial developmental and learning loss [2].At a time when there was an increased need for support, parents often found themselves solely responsible for the care of their children without access to social networks and services.Increased rates of parenting stress, financial insecurity, and exposure to harmful online content led to dramatically increased risks of violence against children and intimate partner violence [3].A meta-analysis found that the global prevalence of child and adolescent depression and anxiety doubled during COVID-19 in comparison with pre-pandemic estimates [4].An additional 10.4 million children were affected by orphanhood and caregiver morbidity due to COVID-19 [5].
Movement restrictions prohibiting face-to-face interactions during COVID-19-related lockdowns forced public health and social service providers to adapt normal service delivery approaches.Although there is considerable evidence demonstrating the effectiveness of face-to-face parenting programs based on social learning and attachment theories [6,7], most of these programs were developed for in-person group-or home-based delivery and were thus not feasible during the pandemic.This led to a proliferation of alternative delivery approaches to provide parenting support, including via telehealth, social media, digital apps, online groups, chatbots, telephone consultations, and other remote methods [8][9][10].
Emerging evidence supports the potential effectiveness of remotely delivered parenting interventions using online platforms, apps, and chatbots on improving parent-child interaction and child development outcomes [11,12].Additional research supports the efficacy of parenting programs delivered via radio and television [13], and there is limited but promising evidence for population-level delivery of parenting support [14].Moreover, two recent studies showed promising results on improving family functioning and reducing child behavior problems through a light-touch parenting intervention using leaflets and informal group conversations with families in the West Bank and Indonesia [15,16].
In response to the increasing risks of violence against children and reduced capacity to provide in-person parenting support during COVID-19, Parenting for Lifelong Health (PLH), a UK-based charity, led an interagency emergency response effort -the COVID-19 Playful Parenting Emergency Response -to rapidly adapt evidence-based parenting programs into freely available, open-source, and culturally sensitive resources.These evidence-informed resources were initially released for public use via the World Health Organization (WHO) and UNICEF COVID-19 websites, alongside a letter in The Lancet [17].The resources focused on building positive parent-child relationships and reducing violence against children by encouraging caregiver playful engagement, reinforcing positive child behaviors managing child difficult behaviors, creating daily structure and routines, talking about COVID-19, keeping children safe online, and reducing caregiver stress and family conflict.
The purpose of this study was to examine the global dissemination of these parenting resources during the height of the COVID-19 pandemic.We used the RE-AIM to examine 1) the adoption of the resources by implementing agencies, including government and nongovernmental organizations (NGOs); 2) their delivery by implementing agencies; 3) the reach, or number of people who received the resources across geographical areas and dissemination methods; 4) their impact on positive parenting, parenting stress, parent efficacy, and child physical and emotional abuse; and 5) their long-term maintenance and use beyond the pandemic [18].

Methods
This real-world study was conducted remotely from March 2020 to July 2021.It was conducted in parallel to a qualitative study examining perceptions of parents and service providers on the usefulness and appropriateness of the parenting resources [19].Ethical approval was granted by the University of Oxford (Ref #R69569) and University of Cape Town (Ref# PSY2021-038).

RE-AIM framework
The RE-AIM framework is one of the most widely used implementation science frameworks to support the understanding of how evidence-based behavioral and public health interventions are integrated into policy and practice [20].It allows for the assessment of multiple implementation science domains across different ecological levels (i.e., individual, organizational, national, etc.).RE-AIM dimensions include 1) Reach: the number, proportion, and representativeness of individuals who participate in a given intervention; 2) Effectiveness: the impact of a given intervention on primary and secondary outcomes as well as potential variability based on population characteristics; 3) Adoption: the level of take up and representativeness by implementers; 4) Implementation: the fidelity and quality of delivery, as well as adaptation, of an evidence-based intervention, particularly as it is delivered in different contexts and cultures; and 5) Maintenance: the extent to which an intervention becomes institutionalized through sustained delivery and the sustainment of effects on an individual level [21].In this study, we adapted the sequencing of RE-AIM to provide further understanding of the global scale-up and impact of the COVID-19 Parenting resources.First, we examined the Adoption and Implementation by implementing partners, governments, and other agencies.Second, we examined the Reach of the COVID-19 Parenting resources.Third, we assessed the Effectiveness, or impact, of the resources on behavioral and mental health outcomes in a multi-country study using retrospective surveys.Finally, we assessed the Maintenance of resources by implementing partners one-year after initial dissemination (see Table 1).

COVID-19 playful parenting resources
The COVID-19 Playful Parenting Resources were developed in March 2020 by adapting core parenting themes from the Parenting for Lifelong Health suite of parenting programs originally developed and tested in LMICs [22].Six initial single-sided tip sheets were created: 1) positive relationship building, 2) positive reinforcement, 3) limit setting, 4) managing misbehavior, 5) coping with stress, and 6) talking about COVID-19.In April 2020, an additional six tip sheets were developed: 7) online child safety, 8) family budgeting, 9) intimate partner relationships, 10) remote educational support, 11) learning through play, and 12) anger management.Specific sheets were also created for families living in crowded homes and communities, those with disabilities, adolescents, and newborns (see Table 2).Each tip sheet distilled evidence-based parenting content into three to four core skills with an overall limit of 150 to 200 words per sheet.Gender-neutral comic characters were developed as part of the design process to increase user-friendliness.The content was framed positively (e.g., "Set aside time to spend with each child") with empathy towards the current experiences of parents and caregivers during COVID-19 (e.g., "It is normal to feel stressed and overwhelmed").Core evidence-based parenting content was also contextualized for COVID-19, such as suggested activities for child-led play during lockdown and specific routines around safe distancing and hygiene.Hyperlinks were also included for additional support as well as to UNICEF and WHO COVID-19 websites (see Fig. 1).
Prior to public release, the resources underwent a rigorous review process with core institutional partners.Creative Commons licensing was selected to allow for the open-source adaptation and replication of the resources freely without any restrictions or payment.In addition, a COVID-19 Playful Parenting dissemination team was established to support the reproduction of the tip sheets into social media toolkits, toolkits for social workers, and audio guides for radio and public service announcements.

Data collection
Data on the adoption, implementation, and reach of the COVID-19 Parenting resources were collected from a total of 697 implementing agencies across 198 countries and territories.Research assistants based between the United Kingdom and South Africa collected data remotely through email correspondence, online surveys, and from social media platforms and Google Analytics.Individuals from 568 organizations who had signed up on the COVID-19 website mailing list or attended regional webinars hosted by UNICEF and the WHO were initially contacted via email requesting information about their dissemination of the resources.Email messages invited them to report either directly via email or via a brief online survey.Those who reported via email were asked to respond to two questions: "How have you shared the COVID-19 Parenting tips?" and "How many people have you reached?" Research assistants then followed up with respondents via email to collect more detailed data on the modality of delivery.The online survey consisting of the following items: 1) a multiple-select question about the modality of delivery, 2) a numeric question on the approximate reach for each selected modality, 3) yes/no ) an open-ended question requesting suggestions for improving the content and delivery of the resources, 7) a yes/no question about whether they knew of any other organizations sharing the resources, 8) referral contact details for these organizations, and 9) an invitation to participate in in-depth interviews on their work supporting parents and children during the pandemic (for more information regarding the qualitative component, please see [19]).We received a total of 265 responses (46.7%) of which 195 were received directly via email (73.6%) and an additional 60 via the online survey (26.4%).Data from a further 129 implementing agencies were also collected by analyzing social media metrics from Twitter, Facebook, LinkedIn, and Instagram and Google Analytics of selected COVID-19 response websites.Research assistants conducted online searches for evidence of uptake, implementation, and reach using key terms and hashtags (e.g., #COVID19parenting).Key implementing partners such as UNICEF and the WHO also reported the number of downloads of the parenting resources using Google Analytics, which was also monitored on the project's own website (www.covid 19par enting.com).
Implementing agencies that responded to the initial surveys were sent a follow-up email in which they were invited to participate in a retrospective study with families in their networks who received the COVID-19 Parenting resources.Thirty-four responses out of 265 potential organizations were received (12.8% response rate), from which 12 organizations volunteered to participate in the (35.2% recruitment rate).These organizations were from 11 countries, including five from Africa (Cameroon, Ghana, Malawi, South Africa, and Zambia), five in Asia (Cambodia, India, Nepal, Pakistan, and Sri Lanka), and one in Europe (North Macedonia).Parent and caregiver respondents (N = 1,303) were primarily recruited by implementing agencies through existing services offering a range of material and psychosocial support during the pandemic.Surveys were administered in a variety of formats, including phone-based interviewing by implementing staff, survey links on organization websites and social media pages, and home visits during provision of other services.
The retrospective survey was designed to be low-cost and simple to administer due to limited human and financial resources available as well as movement restrictions during the pandemic.It included four items on demographic characteristics (i.e., gender, age, number of children, age group of children), two items on method of delivery and type of content delivered (i.e., "Please tell us how you received the COVID-19 parenting messages" and "Which COVID-19 resources did you learn from?"), and six items examining their perceptions of the impact of the parenting resources on their behavior and mental health.These items were derived from psychometrically tested scales and included parent engagement in play, parenting stress, physical child abuse, emotional  Respondents were asked to reflect on the past month after receiving the parenting resources and to indicate on a Likert scale whether they agreed or disagreed with each statement (0 = Strongly disagree; 4 = Strongly agree).Variables were converted to binary variables, with 'strongly agree' and 'agree' grouped as 'agree, ' and 'neutral, ' 'disagree, ' and 'strongly disagree' grouped as 'disagree' .Lastly, respondents were asked an open-ended question about how they used the parenting resources.Data was uploaded securely to a dedicated study site on www.onlin esurv eys.co.uk.All quantitative data were fully anonymous and delinked from IP addresses (Table 3).Additional qualitative data were collected via in-depth interviews with parents, adolescent children, and providers (n = 22) from 14 countries and one global source.These interviews were conducted online using Zoom software, lasted an average of 22.3 min (range 7-46 min), and followed a semi-structured protocol.Qualitative data was analyzed using thematic analysis and is reported in detail in [19].
In April 2021, a final maintenance survey was sent via email to the implementing partners who had previously reported using the COVID-19 Parenting Resources.The surveys consisted of three questions: 1) Is your organization still using the COVID-19 Parenting Resources?If so, how are you using them?2) Have you made any changes/ adaptations to the resources that we provided?and 3) Is there any additional content we can assist with due to the emerging issues/needs your organization is currently facing?Only 44 out of 265 (16.6%) implementing agencies who initial reported using the COVID-19 parenting resources responded to these maintenance surveys oneyear after initial dissemination.

Data analyses
Data analyses used a pragmatic approach based on FUPS principles (i.e., using flawed, uncertain, proximate, and sparse data) [28] given the study's limited financial and human resources.

Adoption
Adoption by implementing agencies was assessed by examining the number and type of organizations that either reported on the delivery of the COVID-19 Parenting resources or were identified during social media platform searches.The type of adopting organization was disaggregated into seven categories: government, international NGO, local NGO, media, faith-based, academia, and individual.

Implementation
Implementation data was analyzed based on the type of delivery modality, number of languages the resources were translated into, and the geographical representation of implementing partners.

Reach
We used a conservative approach to establish an estimate for the absolute number of people who may have received the parenting resources between March 2020 and July 2021.This approach followed recommendations from the UNICEF guidance on Risk Communication and Community Engagement Indicators for COVID-19 Global Response [29].If an implementing agency disseminated the resources across multiple social media platforms, we only included the platform with the highest reach to avoid double counting.Dissemination via the radio was estimated using available data from average listenership for the show that was broadcasting the resources.Otherwise, average hourly listenership was estimated based on radio station reports.Reach was disaggregated by organization type, geography, and dissemination methods (i.e., website visits/downloads, emails, social media, text messages, print media, radio, public service announcements, video, webinars, school-based, phone-based, Multivariate logistic regressions investigated potential factors associated with each behavioral or mental health outcome using odds rations (OR).This was done by first controlling for three participant-level categorical variables (adult gender, adult age, and number of children) and then adding in the source of information (e.g., type of sources or number of sources).When appropriate, generalized linear mixed models (GLMMs) were employed to account for clustering effects, with all variables used in the logistic regression being the fixed effects and the project/country variable being the random effect.Random-intercept, fixed-slope models were used with the assumption that people in the same organization or country exhibited the same relationships between the outcomes and demographic characteristics and that the intercept was allowed to vary for each level of the random effects.Variations in the time between receiving resources and responding to the surveys were accounted for.

Maintenance
Responses from the maintenance survey conducted in April 2021 were analyzed to determine the method of dissemination, whether any adaptations had occurred, and recommendations for future adaptation.We also ran online searches on social media platforms to determine whether any organizations were still using social media to disseminate the resources.

Adoption
Data analysis of adoption identified 697 implementing agencies, organizations, and individuals who disseminated the COVID-19 Playful Parenting resources.Direct dissemination by individuals on their personal social media platforms accounted for 33.0% of known adopters (n = 230).Out of the remaining 467 implementing agencies and organizations, the majority were NGOs, (e.g., Rwanda Refugee Camps, n = 187), followed by international agencies (e.g., UNICEF country offices, n = 93), faith-based organizations (e.g., Catholic Relief Services, n = 48), media-based organizations (n = 46), government agencies (n = 43), academic institutions (n = 39), and the private sector (n = 12) (see

Sample demographics
Online retrospective surveys were completed by 1,303 caregivers from 12 implementing agencies, with the number of respondents ranging from 12 to 241 per agency.Of the respondents, 949 (72.8%) were female.The mean caregiver age was 40.37 years (SD 10.47; 17-86).In terms of child age, 15.8% (n = 217) of the caregivers had an infant or toddler aged 0-23 months; 58.5% (n = 802) of them had a young child between 2-9 years; and 64.0%(n = 877) had a teenager aged 10-17 years.One-fifth of the respondents had four or more children in the household (20.6%, n = 283) (Table 8).

Perceived impact on parenting, stress and self-efficacy
After receiving the parenting tips, 84.3% of the respondents reported that they were spending more time playing with children, 75.7% felt more capable of managing parenting stress, 79.4% reported using less physical discipline, 76.9% yelled at children less frequently, 92.2% agreed felt more confident in building positive parentchild relationships, and 85.6% had increased self-efficacy in protecting children from sexual abuse (Table 9).).Analyses also found differences by caregiver gender, with female caregivers more likely to agree that they were using less physical discipline (OR = 0.45, 95%CI [0.33, 0.61]) and yelling less at their children (OR = 0.56, 95%CI [0.42,0.76])than male caregivers.Parental self-efficacy in building positive parent-child relationships was similar across different demographic characteristics (Table 10).

Maintenance
Out of the 44 implementing agencies who responded to the short surveys inquiring whether they were still using the COVID-19 parenting resources one year after initial dissemination, 14 (31.8%)shared that the resources were still on their website and 18 (40.1%)reported that they had adapted the resources for digital delivery via chatbots, apps, and social media as part of routine service delivery.Four organizations reported ongoing use of the resources in their weekly parenting sessions and visits to early childhood centers.For example, Forgotten Voices reported that they had integrated the parenting tips within programs for orphan care and faith groups in Malawi and Zambia.Likewise, the Philippine government continued to use the resources as part of their online family development services delivered as part of a conditional cash transfer program for more than four million low-income families [30].

Discussion
This study is the first of its kind to evaluate the global dissemination of a behavior change intervention aimed at supporting parents during an international crisis.It complements a parallel qualitative research study of the COVID-19 parenting resources that found high levels of perceived accessibility, cultural acceptability, and impact by implementing agencies, local communities, and parents [19].It used the RE-AIM framework to examine their adoption, implementation, reach, effectiveness, and maintenance from a multidimensional perspective.
Findings suggest the utility of developing open-source and easily adaptable resources from evidence-based parenting programs to allow for rapid adoption, localization, and deployment.The COVID-19 Parenting response was an unprecedented collaboration with universities, NGOs, international agencies, and governments to provide immediate support to parents and caregivers during the pandemic.Their rapid adoption by 697 implementing partners was facilitated by the endorsement of UN international agencies such as the WHO, UNICEF, and UNODC, which provided both institutional legitimacy and access to a diverse network of implementers.The development of the resources by researchers from academic institutions may also have contributed to their legitimacy as parenting tips derived from "evidencebased" and "scientifically tested" programs previously evaluated in randomized controlled trials.This finding is consistent with prior research emphasizing the importance of partnerships and collaborative strategies in the successful implementation of public health interventions [32].In particular, the adoption by 43 government agencies highlights the utility of leveraging a vast dissemination network that included individuals and organizations with pre-existing partnerships with government counterparts.The rapid adoption also underscores the importance of making evidence-based parenting intervention materials freely available and open-source through Creative Commons licensing which allowed for rapid dissemination at scale [33].Lastly, the customization of the evidence-based parenting intervention content to the COVID-19 context may have been a critical factor of success by making sure that they were relevant to the experiences of parents across multiple settings.
In addition to the intentional development of freely available and adaptable resources, the widescale implementation of the parenting resources was also facilitated by their accessibility in local languages.The collaboration involved over 300 volunteer translators who translated the resources into 135 languages and dialects in less than a month, with expert reviewers and local implementing partners conducting quality control checks.Once provided in a local language, implementers were able to adapt the resources to fit local cultures and delivery contexts, which was essential to ensure that the resources were culturally relevant to recipients [34].Although the most common delivery method was via social media platforms, implementation also included other innovative approaches, such as using community loudspeakers for public service announcements, caseworker toolkits, radio announcements, and faith-based guides.In addition, the availability of targeted microgrants allowed local community-based organizations to overcome implementation barriers by providing immediate funds for printing, broadcasting, or even home-based delivery.This approach aligns with literature on the adaptability and flexibility required for implementing population-level behavioral interventions, particularly in diverse cultural contexts [35].
The global reach of the COVID-19 Parenting resources represents an unprecedented level of dissemination to over 212 million individuals.This emphasizes the potential of using digital platforms to disseminate behavioral interventions at a population level [36].It also aligns with previous research highlighting the role of social media in health communication and behavior change [37].While the overall reach was dominated by social media, it is important to consider other platforms, such as radio, in reaching populations with limited access to the internet.Radio broadcasts have been effective in delivering health messages to remote and underserved communities, particularly in LMICs where access to digital technology is limited [38].This combined approach, harnessing digital and traditional media along with other forms of face-to-face delivery, exemplifies the need for an integrative strategy to ensure equitable access to public health interventions [39].Findings indicating a higher proportion of reach by geographical region in Africa and Asia may have been due to respondent biases and keyword searches primarily in English.Furthermore, although it is potential that the reach was greater in other geographical regions, it was not possible to disaggregate data from global sources that could not be attributed to a specific region or country.
Retrospective surveys across 11 countries suggested positive impacts of the COVID-19 Parenting resources.Parents reported increased parent-child play and parenting self-efficacy with decreases in parenting stress and child physical and emotional abuse.These findings are encouraging, considering global reports of increased violence against children and mental health problems during the pandemic [1,40].They also align with previous research on the effectiveness of in-person parenting programs in improving parent-child interactions, reducing harsh discipline, and enhancing positive parenting practices [6,7].Analyses exploring potential differential effects by demographic characteristics showed that younger caregivers were more likely to spend more time playing with their children and manage parenting stress effectively than older caregivers.Although this contradicts global systematic reviews indicating that parenting programs are generally as effective across parent age [7], younger caregivers may have had more access to the online parenting support due to higher levels of digital literacy.We also found gender differences, with female caregivers reporting more substantial reductions in physical and emotional abuse.This may be due to gender imbalances in caregiving responsibilities, in which female caregivers spend more time with their children and are often responsible for discipline [41].It also corresponds to findings from a multi-country study across nine countries in which female caregivers used corporal punishment more frequently than male caregivers [42].However, this may also be due to under-reporting by female caregivers or the fact that while male caregivers may use physical discipline less frequently, they often use more harsh forms of discipline [43].Nonetheless, one must caution interpretation of these results due to the retrospective design (i.e., no baseline assessments), lack of a comparison group, and potential social desirability bias of self-reported responses.
While only a limited number of implementing agencies responded to follow-up surveys on the maintenance of the COVID-19 Parenting resources, results suggested their sustained delivery as they continued to be adapted and repurposed for other contexts.The adaptation of the resources to address emerging humanitarian crises is particularly encouraging considering the need for immediate parenting and child protection support during the onset of humanitarian disasters prior to the delivery of more intensive group-based programs [44].In addition, the integration of the resources within the conditional cash transfer program for families in the Philippines suggests the importance of government adoption and institutionalization to promote positive parenting behaviors [45].

Limitations and strengths
Several limitations are worth noting.First, reach numbers must be treated with caution since they relied on available data collected by a small, dedicated research team tracking reach across multiple platforms and selfreport surveys by implementing partners.It is possible that we have overestimated reach by double-counting individuals.Even though we adopted a conservative approach that included limiting reach to one social media platform per implementing agency, individuals may have received parenting resources from multiple implementers.Likewise, estimates of absolute reach via social media and other platforms, such as radio, were operationalized based on the total number of followers or average listenership.These calculations assume passive engagement by individuals, rather than active engagement which could have been operationalized based on engagement data (i.e., likes, comments, shares).Although we considered using engagement data to calculate reach via social media, we decided against this approach since it could have potentially miss individuals who may not have actively interacted in the posts or responded to radio programs.Nonetheless, this may have overestimated the actual reach of the resources.
The use of retrospective surveys limits our ability to draw firm conclusions on the effectiveness of the resources.Data collection was limited to agencies and individuals who were willing to participate in the study, potentially introducing selection bias.Those who chose to respond may have had more positive experiences with the intervention, thus potentially overestimating its impact.Results from retrospective data may also have been imprecise due to potential recall bias and lacked a comparison group.Their generalizability is also limited since the sample only reflected a small proportion of the total reach population.In addition, retrospective surveys relied on abbreviated one-item outcome measures, which although derived from longer, psychometrically tested scales, were not validated.Lastly, low response rates to the maintenance survey limited our ability to assess the sustainability of the COVID-19 Parenting resources beyond a small sample size.To provide a more complete understanding of the intervention's maintenance and impact over time, longer-term and more comprehensive follow-up studies are warranted [46].Despite these limitations, this study is unique in its real-world, global scope.It provides valuable insights into the implementation of population-level behavioral interventions during the COVID-19 pandemic across several key indicators linked to implementation science.The use of multiple sources of data collection, including email and online surveys, social media metrics, and retrospective surveys with target beneficiaries, offers a rich and multifaceted understanding of real-world implementation of content derived from evidence-based parenting programs at scale.Its application of the RE-AIM framework demonstrates how implementation science methods can be used to assess the dissemination of a complex behavior change intervention during a global crisis.It underscores the pivotal role of implementation science in promoting the translation of research into practice, with potential applications in various domains, including public health, global health, community-based interventions, child development, and climate response.

Implications for future research and practice
The findings of this study have several implications for future research and practice.First, it underscores the need for continued research to build a stronger evidence base for the effectiveness and maintenance of population-level parenting support interventions during public health emergencies.It provides a blueprint on how to adapt evidence-based interventions into applied resources and underscores the vital importance of allocating sufficient resources to conduct evaluations during dissemination.Although challenging to conduct in times of acute crisis, more robust research designs, including randomized trials, are essential for establishing causal relationships between the use of resources and the observed outcomes.The trial of Parent Positivein the United Kingdom is an innovative example in which researchers were able to rapidly develop a parenting app and test it using a randomized design during the pandemic by leveraging an existing cohort study [47].Second, the study highlights the importance of interagency collaboration at both national and global levels to effectively address public health crises.The engagement of a diverse range of implementing agencies, including governments, NGOs, faith-based organizations, and academia, demonstrates the ongoing need for collective efforts to reach and support families during crises.Third, the study suggests the potential of diverse platforms for dissemination, such as radio and community broadcasts, particularly in regions with limited internet access [13].Finally, this study highlights the benefits of making evidence-based interventions freely available so that they can be widely adopted and customized for local populations [33].

Lastly, the COVID-19 Parenting dissemination team developed new resources to support caregivers when children were returning to school and challenges around COVID-19-related bereavement -an emerging need given recent data estimating that 10.5 million children have been orphaned due to the pandemic [5].The COVID-19 Parenting resources were also adapted for other humanitarian crises.These included adaptations for families affected by floods in Malaysia and typhoons in the Philippines in December 2021.Two years after the initial resources were developed, Parenting for Lifelong Health, one of the lead agencies in the COVID-19 Playful Parenting Emergency Response, adapted the resources for families affected by the crisis in Ukraine, which have reached an estimated 11.5 million people since 2022 [31].The resources have also been adapted to support families affected by floods in Pakistan in 2022, recent earthquakes in Turkey/Syria and Afghanistan in 2023, and additional conflicts in Sudan and Israel/Palestine in 2023 and 2024.These adapted resources are available online available at https:// www.paren tingf orlif elong health.org/ crisis and via the Global Initiative to Support Parents website (https:// suppo rt-paren ts.org/ paren ting-in-crisis/).
These included representatives from UNICEF, WHO, USAID, UNODC, the Global Partnership to End Violence Against Children, Clowns Without Borders South Africa, the Early Childhood Development Action Network, World Without Orphans, the Centers for Disease Control and Prevention, and the World Childhood Foundation.Subsequent translation into 135 languages and dialects involved 192 volunteers recruited primarily via Facebook, with additional support from World Without Orphans, Translators Without Borders, and volunteers from Generali Insurance and The Human Safety Net.
