Aims Despite their advantages, longitudinal studies often face high rates of attrition. This study documents the extensive efforts associated with retaining a longitudinal cohort last contacted 10 years earlier. Method We examine the processes and outcomes of attempts to reach 1736 individuals who have been part of a multiwave study about growing up in Ontario, Canada. Contact methods include email, phone, text, social media, postal mail, announcements in newspapers, subway stations, and music streaming services. Results Challenges included a lack of consistent annual communication with participants, children moving out of the parental home, and changes in email addresses and phone numbers. The most effective contact method was phone; text messages and friend referrals were the least effective. Overall, 41.5% of the original sample was reached. Locating former research participants years later necessitated multiple and repeated contact attempts, and intensive human resources. Conclusion Ten lessons for effective sample retention are discussed. In summary, reducing attrition depends on a comprehensive study design and an organized and flexible protocol that adapts to a study's ever‐changing needs.

Better Beginnings Waterloo (BBW) is an ecological, community-driven, prevention program for children aged 4–8 and their families. BBW was implemented in two low-income communities with high percentages of visible minorities. Data on Grade 1–2 children and their parents (the baseline comparison group) were gathered through parent interviews (n = 34) and teacher reports (n = 68) in 2015, prior to BBW programs, and in the period 2018–2019, the same data were collected through parent interviews (n = 47) and teacher reports (n = 46) for children and parents participating in programs (the BBW group). As well, qualitative, open-ended individual interviews with parents (n = 47) and two focus groups were conducted in the period 2018–2019. Children in the BBW cohort were rated by their teachers as having a significantly lower level of emotional and behavioural problems than those in the baseline sample; parents in the BBW cohort had significantly higher levels of social support than parents in the baseline cohort; BBW parents rated their communities significantly more positively than parents at baseline. The qualitative data confirmed these findings. The quantitative and qualitative short-term findings from the BBW research showed similar positive impacts to previous research on program effectiveness, thus demonstrating that the Better Beginnings model can be successfully transferred to new communities.

This chapter examines the historical and current uses of global citizenship education (GCE) in Canada and the U.S. in public schools from primary through secondary levels, with attention to Canada as well as similarities and differences within and across the two countries. We assess how social and political contexts have influenced the definition and operationalization of multiculturalism, civic studies, and global studies in curricula, noting that the neo-liberal perspective has focused on making people an economic powerhouse rather than socially concerned global citizens. In our examination of educational approaches that relate to GCE, we present decolonizing pedagogies, the multiculturalism approach in Canada, as well as culturally responsive and anti-racist pedagogies. To illustrate these issues, we offer an example in the Canadian context and raise the need to prevent GCE from becoming yet another tool for hegemony by the Global North on the Global South, as dominant groups have long defined citizenship. We conclude by proposing that to realize GCE in these two countries, teacher/practitioner and local, national, and international actors must engage youth, and in doing so, power imbalances that prohibit becoming global citizens will be addressed.
