Implementation and effectiveness of a school-based intervention to increase adherence to national school meal guidelines: a non-randomised controlled trial.

OBJECTIVE: Implementation of school meal guidelines is often inadequate, and evidence for effective implementation strategies for school-based nutrition interventions is limited. The aim of the present study was to examine the implementation and effectiveness of a multi-strategy implementation intervention to increase adherence to the Norwegian national school meal guideline. DESIGN: The study was a school-based hybrid implementation effectiveness trial with a pre-post non-equivalent control group design, testing three implementation strategies: internal facilitation, training and an educational meeting. SETTING: Primary schools and after-school services in two counties in south-east Norway. PARTICIPANTS: School principals, after-school leaders and class teachers from thirty-three schools in the intervention county and principals and after-school leaders from thirty-four schools in a comparison county. RESULTS: There was a significant difference of 4 percentage points in change scores between the intervention and the comparison groups at follow-up, after adjusting for baseline adherence (B = 0·04, seB = 0·01, t = 3·10, P = 0·003). The intervention effect was not associated with the school's socio-economic profile. School-level fidelity was the implementation dimension that was most strongly correlated (r s = 0·48) with the change scores in the intervention group, indicating that principals' support is important for gaining the largest intervention effects. CONCLUSIONS: A school-based intervention with low intensity, based on trained teachers as internal facilitators, can increase adherence to the national school meal guideline among Norwegian primary schools, irrespective of local socio-economic conditions. Implementation fidelity, at an organisational level, may be a useful predictor for intervention outcomes in schools.

The mediating effects of motivation on the relations between occupational stress and physical activity among underresourced afterschool program staff.

OBJECTIVE: Guided by Self-Determination Theory, this study aimed to examine the potential mediating effects of autonomous and controlled motivations on physical activity (PA) experiences of afterschool program (ASP) staff with occupational stress. METHOD: A total of 58 ASP staff provided full data. Staff occupational stress and self-determination motivations for PA were assessed. Participants' daily moderate-to-vigorous physical activity (MVPA) was measured using accelerometer wear. A path analysis was used to address the research purpose. RESULTS: Occupational stress negatively and indirectly predicted daily MVPA which was mediated by controlled motivation (ß = - 4.15, p <.05). Autonomous motivation directly and positively predicted daily MVPA across all types and levels of ASP staff occupational stress (ß = 9.93, p =.01). CONCLUSIONS: Autonomous motivation is a powerful predictor of staff PA levels despite the degree to which they experience stress. In contrast, controlled motivations are more vulnerable to occupational stress, and can lead to lower MVPA.

Adolescents' exposure to community violence and associations with after-school activities across two samples.

INTRODUCTION: Exposure to community violence (ECV) continues to be a major public health problem among urban adolescents in the United States. We sought to identify subgroups of adolescents' ECV and examine how after-school activities are related to exposure subgroups across two samples. METHODS: In Study 1 there were 1432 adolescents (Cohort 9 n = 717, Mage = 11, and Cohort 12 n = 715, Mage = 14; 52% boys) from the Project on Human Development in Chicago Neighborhoods (1994-2002). Study 2 had a more recent sample of 537 adolescents (Mage = 16 years; 54% girls) from the After-School Activity Study (ASAS; 2015-2017) in Chicago and Detroit. RESULTS: Exploratory latent class analyses yielded a three-class solution for Study 1: a "No ECV" class (44%); a "Low ECV" class (36%); and a "High Exposure" class (14%). In Study 2, a four-class solution was the best fit with a "No ECV" class (33%), a "Moderate Witness/Low Victim" class (36%), a "High Witness/Moderate Victim" class (19%), and a "High ECV" class (11%). Home-based activities appeared to be protective against high ECV for adolescents in Study 2. School-based activities were associated with higher ECV across both samples, but community-based activities were only associated with greater violence exposure in Study 1. Adolescents' unstructured socializing in both studies was associated with higher odds of ECV. CONCLUSIONS: Results indicate that subgroups of adolescents can be identified based on ECV and highlight the complexity of after-school activities as risk and protective factors in both past and more recent contexts.

Cognitively engaging movement games improve interference control and academic performance in overweight children: A randomized control trial.

The purpose of this study was to determine the (a) dose-response effects of cognitively engaging movement games (CEMGs) designed to improve aerobic capacity, interference control (IC), and academic performance, (b) relationship between intervention-induced improvements in aerobic capacity, IC, and academic performance, and (c) moderation effect of IC on the relationship between aerobic capacity and academic performance in overweight children. Seventy-five overweight children (aged 11.23 ± 0.60 years; 48% males) participated in this study conducted in Taipei during the 2018/2019 academic year and were randomly assigned to the low-dose (20-min) intervention, high-dose (40-min) intervention, and control groups and completed a Stroop test, half-mile run, and language and mathematics tests before and after a 10-week afterschool program. Both intervention groups showed similar improvements in outcomes of aerobic capacity (ds > 0.80), IC (ds > 0.76), and academic performance (ds > 0.90) from the pretest to posttest, whereas these outcomes were unchanged for the control group. Furthermore, improved IC moderated the association between improvements in aerobic capacity and academic performance. Our findings suggest that CEMG with varying doses is feasible and effective for improving aerobic capacity, IC, and academic performance in overweight children and that the association between improvements in aerobic capacity and academic performance depends on the intervention effects on IC.

Participation and enjoyment in Out-of-School activities during adolescence as predictors of activities in adulthood.

This study examined associations between adolescents' participation in out-of-school activities and their participation in activities at age 26 (N = 1041, 50% girls, 77% White). More frequent adolescent participation in sports, arts, volunteer/community service, and religious activities increased the odds of participating in the same type of activity at age 26. Adolescents' enjoyment of activities partially explained the developmental continuity in activity participation. There was limited evidence that individuals' participation across different types of activities was associated. Finally, the diversity or breadth of adolescents' activity participation was associated with larger activity breadth at age 26. These findings suggest that adolescents' out-of-school activities help set the stage for participating in similar, but not different activities during young adulthood.

The influence of social support, social affiliation and intrinsic motivation for increasing underserved youth's physical activity: A social climate-based intervention study.

The purpose of this study was to investigate the influences of intrinsic motivation, social affiliation orientations and reciprocal social support for physical activity (PA) on underserved youths' afterschool period moderate-to-vigorous (MVPA) changing trajectories across the 16-week Connect through PLAY intervention, a social-motivational climate intervention. A total of 113 youth (61.06% African American, 56.64% girls) provided full data. Youths' intrinsic motivation, social affiliation orientations and social support were measured by youth responses to a set of surveys at baseline and post-intervention. Youths' afterschool period MVPA was measured using data from 7-day ActiGraph accelerometer wear at baseline, midpoint and post-intervention. Hierarchical linear modelling analysis found that youth daily afterschool period (3pm-6pm) MVPA increased, on average, 37.94 min across the 16-week intervention. Increases in intrinsic motivation, social affiliation orientations and social support were positive predictors of youth afterschool MVPA changing trajectory. The findings clarify the contributions that a social-motivational climate intervention can have on youth afterschool period MVPA through increasing youth intrinsic motivation, social affiliation and reciprocal social support.

Project DREAM: Iterative development of an afterschool program with an emphasis on youth-adult relationships.

The current manuscript describes the iterative development of an afterschool intervention aimed at fostering supportive relationships between adolescents and adults from their everyday lives. Project DREAM (Developing Resourcefulness, Engagement, Acceptance, and Mentoring) is a novel afterschool preventive intervention aimed at promoting youths' improved academic outcomes via gains in social and emotional development and their connectedness with nonparental adults. The purpose of the iterative development process was to improve the intervention to make it maximally usable and acceptable to the intended users and participants. The iterative development process was informed by data collected from advisory boards, focus groups, interviews, and observations of program sessions. In the current article, we describe the methods implemented as part of this process and fully describe the resulting intervention revisions completed across the 2-year period. We also summarize lessons learned.

Foods and beverages provided in out of school hours care services: an observational study.

INTRODUCTION: Out of school hours care (OSHC) is a fast-growing childcare setting in Australia, however the types of foods and beverages offered are relatively unknown. This study describes the food and beverages offered and investigates sector-level and setting-level factors which may impact OSHC in meeting the Australian Dietary Guidelines (ADG). METHODS: This cross-sectional, observational study was conducted in 89 OSHC services (between 2018 and 2019). Food and beverages offered, kitchen facilities and menus were captured via direct observation. Foods were categorised into five food groups or discretionary foods, based on the ADG, and frequencies determined. Short interviews with OSHC directors ascertained healthy eating policies, staff training, food quality assessment methods and food budgets. Fisher's exact test explored the influence of sector-level and setting-level factors on food provision behaviours. RESULTS: Discretionary foods (1.5 ± 0.68) were offered more frequently than vegetables (0.82 ± 0.80) (p < .001), dairy (0.97 ± 0.81) (p = .013) and lean meats (0.22 ± 0.54) (p < .001). OSHC associated with long day care and reported using valid food quality assessment methods offered more lean meats (p= .002, and p= .004). Larger organisations offered more vegetables (p = .015) and discretionary foods (p= .007). Menus with clearly worded instructions to provide fruits and vegetables daily offered more fruit (p= .009), vegetables (p < .001) and whole grains (p= .003). No other sector or setting-level factors were associated with services aligning with the ADG. CONCLUSION: Future interventions could benefit from trialling menu planning training and tools to assist OSHC services in NSW meet the ADG requirements.

The relationships between school children's wellbeing, socio-economic disadvantage and after-school activities: a cross-sectional study.

BACKGROUND: Lower socioeconomic status is associated with poorer wellbeing among children. Identifying how children participate in after-school activities and how after-school activities are associated with wellbeing may inform interventions to improve wellbeing among children from low socioeconomic backgrounds. This study explored whether children's after-school activities varied by socioeconomic status and examined the associations between after-school activities and wellbeing in low socioeconomic status children. METHODS: This study analysed cross-sectional data from 61,759 school students in years 4 to 9 who completed the 2018 South Australian Wellbeing and Engagement Collection. Students reported the number of days per week they participated in 12 activities (after-school care, homework, music lessons or practice, youth organisations, sports, television, videogames, social media, reading, chores, arts and crafts, and socialising with friends) during the after-school period (3-6 pm) and their wellbeing (happiness, sadness, worry, engagement, perseverance, optimism, emotion regulation, and life satisfaction). Socioeconomic status was measured by parents' highest education level obtained from school enrolment data. Linear multilevel models were used to examine whether frequency of after-school activities varied by socioeconomic status. Multilevel ordered logit models were used to analyse the association between after-school activities and wellbeing amongst participants in the low socioeconomic status category. RESULTS: After-school activities differed according to socioeconomic status; high socioeconomic status children did more frequent sport, homework, and reading and low socioeconomic status children did more frequent screen-based activities (TV, videogames and social media). Among children from low socioeconomic status backgrounds, higher wellbeing was associated most consistently with more frequent sports participation, homework, reading and spending time with friends and less frequent videogames, social media and after-school care. CONCLUSIONS: Children's wellbeing is positively associated with socioeconomic status. Amongst children from disadvantaged backgrounds, participating in sport, spending time with friends and getting less screen time may be protective for wellbeing. The results suggest that programming targeted at increasing sports participation and reducing screen time amongst children from low socioeconomic status backgrounds may support their wellbeing.

Understanding afterschool engagement: Investigating developmental outcomes for adolescents.

Though student engagement is hypothesized to be a factor in explaining student level differences in afterschool programs, the measurement of student engagement in this context is inconsistent, and findings from the small number of studies about how engagement impacts developmental and academic outcomes are mixed. In this study, we tested the factor structure of Wang and colleagues' school engagement scale with a sample of middle school students (N = 197) who attended an afterschool program in an urban setting. Results suggest that a bifactor model of engagement best fits the data, meaning that engagement consists of four specific factors (affective, behavioral, cognitive, social) and a global factor. We then used structural equation modeling to examine the relationship between engagement, academic outcomes, and positive youth development (PYD). Results also showed positive associations with student mathematics achievement and PYD, but no significant associations were found between engagement and English achievement. This study provides a theoretically aligned way to measure engagement and evidence to support engagement as a key factor in predicting youth outcomes in an out-of-school context.

Native Spirit: Development of a culturally grounded after-school program to promote well-being among American Indian adolescents.

Culturally grounded after-school programs (ASPs), based on local cultural values and practices, are often developed and implemented by and for the local community. Culturally grounded programs promote health and well-being for American Indian and Alaska Native (AI/AN) adolescents by allowing them to reconnect to cultural teachings that have faced attempted historical and contemporary erasure. This article is a first-person account that describes the development and implementation of a culturally grounded ASP, Native Spirit (NS), for AI adolescents (grades 7-12) living on a Southwest urban-based reservation. NS, a 13-session culturally grounded ASP, was developed by an academic-community partnership that focuses on increasing cultural engagement as a form of positive youth development. Each session was guided by one to two local cultural practitioners and community leaders. The development of the NS program contributed to an Indigenous prevention science that emphasizes the positive impacts of Indigenous culture and community on health and well-being. The use of the ASP format, in partnership with the Boys & Girls Club, increased the feasibility of dissemination and refinement of the NS program by tribal communities and organizations.

Physical activity in out of school hours care: an observational study.

BACKGROUND: Opportunities for physical activity within out of school hours care (OSHC) are not well documented in Australia. This study explored factors associated with children (5-12 years) meeting 30 min of moderate to vigorous physical activity (MVPA) while attending OSHC in the afternoon period. METHODS: A cross-sectional study, conducted in 89 OSHC services in New South Wales, Australia, serving 4,408 children. Each service was visited twice between 2018-2019. Physical activity promotion practices were captured via short interviews and System for Observing Staff Promotion of Physical Activity and Nutrition (SOSPAN). Physical activity spaces was measured (m2) and physical activity of 3,614 child days (42% girls), were collected using Acti-Graph accelerometers. Association between program practices and children accumulation of MVPA was tested using mixed effects logistic regression, adjusted by OSHC service and child. RESULTS: Twenty-six percent of children (n = 925) accumulated 30 min or more of MVPA. Factors associated with children reaching MVPA recommendations included: services scheduling greater amounts of child-led free play, both 30-59 min (OR 2.6, 95%CI 1.70, 3.98) and ≥ 60 min (OR 6.4, 95%CI 3.90, 10.49); opportunities for staff-led organised play of ≥ 30 min (OR 2.3, 95%CI 1.47, 3.83); and active games that engaged the majority of children (OR 1.7, 95%CI 1.11, 2.61). Children were less likely to meet MVPA recommendations if services played games with elimination components (OR 0.56, 95%CI 0.37, 0.86). CONCLUSION: Improvements to service-level physical activity promotion practices, specifically the type of physical activity scheduled and the structure of games, may be an effective strategy to increase MVPA of children attending OSHC afterschool in NSW, Australia.

Systematic observation of healthy eating environments in after-school services: a cross-sectional study.

OBJECTIVES: Few studies have examined the healthy eating environments within the Australian out of school hours care (OSHC) setting. This study aims to describe healthy eating environments, consisting of: (a) the alignment of provided food and beverages to Australian Dietary Guidelines; (b) healthy eating promotion practices; (c) nutrition education through cooking experiences; (d) staff role modelling healthy eating and (e) regular water availability. DESIGN: A cross-sectional study was conducted using direct observations and the validated System for Observing Staff Promotion of Activity and Nutrition (SOSPAN) tool. SETTING: OSHC located in urban and semi-rural regions of NSW, Australia. PARTICIPANTS: Staff (151) and children (1549) attending twelve OSHC services operating in the hours after school. RESULTS: Fifty per cent (50 %) of services offered fruits and 100 % offered water as a part of the afternoon snack on all four observation days. Discretionary foods were offered on more days compared to vegetables (+1·9/d, P = 0·009), lean meats (+2·7/d, P =·0 004) and wholegrains (+2·8/d, P = 0 002). Staff promoted healthy eating on 15 % of days, sat and ate with children 52 %, consumed high sugar drinks 15 % and ate discretionary foods in front of children 8 % of days, respectively. No opportunities for cooking or nutrition education were observed. CONCLUSION: Afternoon snacks regularly contained fruits and water. Opportunities exist to improve the frequency by which vegetables, wholegrains and lean meats are offered in addition to staff healthy eating promotion behaviours. Future research is warranted to further explore healthy eating behaviours, practices and policies within the after-school sector.

After-school nutrition education programme improves eating behaviour in economically disadvantaged adolescents.

OBJECTIVE: To investigate whether an after-school nutrition education (ASNE) programme can improve the nutrition knowledge and healthy eating behaviour of adolescents from economically disadvantaged families. DESIGN: One-group pretest and posttest design. Nutrition knowledge and dietary intake were collected using a questionnaire, and anthropometric measurements were measured before and after the intervention. Nine components of healthy eating behaviour were assessed with reference to the Dietary Guideline of Taiwan. Pretest and posttest differences were analysed using generalised estimating equations. SETTING: Three after-school programmes in central and southern Taiwan. The ASNE programme comprised three monthly 1-h sessions (20-30-min lecture and 30-40-min interaction). PARTICIPANTS: A total of 153 adolescents aged 10-15 years from economically disadvantaged families (seventy-eight elementary students and seventy-five junior high school students). RESULTS: Elementary and junior high school students' nutrition knowledge scores (range 0-6) increased by 0·28 (+ 5·7 %, P = 0·02) and 0·30 points (+ 6·18 %, P = 0·02), respectively, but their fruit intake decreased by 0·36 serving/d (-22·9 %, P = 0·02) and 0·29 serving/d (-18·9 %, P = 0·03), respectively. Junior high school students' mean snacking frequency and fried food intake dropped to 0·75 d/week (-21·3 %, P = 0·008) and 0·10 serving/d (-28·8 %, P = 0·01), respectively. CONCLUSIONS: Short-term ASNE programmes can increase nutrition knowledge and reduce snacking frequency and fried food intake despite a decrease in fruit intake among adolescents from economically disadvantaged families.

Implementation of the Norwegian school meal guideline: Development and reliability of two questionnaires to measure adherence.

Aims: This article reports on the development and reliability of two questionnaires that measure adherence to the Norwegian National Guideline on Food and Meals in School among primary schools and after-school services. Methods: Questionnaires for school principals and after-school leaders were developed systematically, using the following steps: (a) selection of scope, questions and adherence values; (b) face validity testing through expert review of initial drafts; (c) content validity testing through 19 cognitive interviews; (d) assessment of test-retest reliability in samples of principals (n = 54) and after-school leaders (n = 47); and (e) development of adherence indices. Results: The cognitive interviews led to substantial revisions of the draft questionnaires, increasing content validity through improved relevance and clarity. Test-retest assessment showed that Cohen's κ ranged from -0.03 to 1.0 for principals and from -0.05 to 0.98 for after-school leaders, with 64 and 53% of values rated as 'substantial' or better. Percentage agreement averaged 85% among principals and 82% among after-school leaders. Intraclass correlation for the adherence index scores was 0.84 for principals and 0.91 for after-school leaders. Guideline adherence had a wide range in our samples, with an average of 71% for schools and 76% for after-school services. Conclusion: The questionnaires for measuring adherence to the national school meal guideline among primary schools and after-school services are sufficiently reliable for future use in public health evaluation and research.

Trends in health behavior and weight outcomes following enhanced afterschool programming participation.

BACKGROUND: The United States needs to increase access to effective obesity prevention and treatment programming for impoverished youth at risk for health disparities. Although recommended, schools have difficulty consistently implement evidence-based obesity programing. We report on the effectiveness of adding structured nutrition education and minimum physical activity (PA) requirements to standard middle school after-school programming. METHODS: Using a longitudinal pre-post study design, we evaluated program effectiveness at one year on target behaviors on students recruited during three consecutive school years (2016-2018). We used generalized linear (or logistic) mixed-effects modeling to determine: 1) impact on healthy weight and target healthy behavior attainment, and 2) whether target behavior improvement and weight change were associated with after-school program attendance. The seven target behaviors relate to eating healthy, physical activity, and sleep. RESULTS: Over the three years, a total of 76 students enrolled and completed one year of programming (62% Hispanic, 46% girls, 72% with BMI > 85th %ile, 49% with BMI > 95th %ile). Of students with BMI > 85th %ile, 44% maintained or decreased BMI Z-score. There were improvements (non-significant) in BMI Z-score and the adoption of four healthy eating behaviors: fruit, vegetables, sugar-free beverages, and unhealthy snack food. Students with higher after-school attendance (> 75%) had greater improvements (non-significant) in composite behavior scores, BMI Z-score, and in most target behaviors (5/7) than students with lower after-school attendance (< 75%). Sleep improvements were significantly associated with BMI Z-score decrease (Beta = - 0.05, 95% CI (- 0.1,-0.003), p = 0.038.) CONCLUSIONS: Enhancement of existing after-school programming with structured nutrition education and minimum physical activity requirements demonstrates positive improvements in several health behaviors and weight outcomes. Adopting enhanced after-school programming increases access to health activities and may bring us closer to solving obesity in at-risk youth in impoverished communities.

Lifestyle habits associated with screen time among pupils in Japan.

BACKGROUND: Media use is pervasive among pupils. This study aimed to determine lifestyle factors associated with screen time. METHODS: The study used a cross-sectional design, and 2,722 questionnaires obtained from pupils in grades 5-12 were analyzed. Multiple regression analysis was used to determine significant lifestyle factors associated with screen time. Grade, gender, bedtime and waking time on both school days and non-school days, academic performance, sleepiness, breakfast, dinner regularity, defecation habits, hours of after-school activities, physical activity, and body mass index were used as the variables. RESULTS: Significant regression formulae were obtained for all school types: adjusted R2 /P values were 0.21/<0.001 for elementary school, 0.21/<0.001 for junior high school, and 0.14/<0.001 for high school. Later non-school-day bedtime (standardized regression coefficient/P values were 0.14/< 0.001 for elementary school, 0.14/<0.001 for junior high school, and 0.09/<0.05 for high school) was significantly associated with increased screen time for all school types. In both elementary and junior high schools, more sleepiness (0.12/<0.001 for elementary school, 0.13/<0.001 for junior high school), shorter after-school activity (-0.24/<0.001 for elementary school, -0.19/<0.001 for junior high school), and higher standardized body mass index (0.08/<0.05 for elementary school, 0.08/<0.01 for junior high school) were significantly associated with screen time increase. In both junior and senior high schools, breakfast skipping (0.15/<0.001 for junior school, 0.14/<0.001 for high school) revealed a significant association with screen time increase. CONCLUSIONS: Media use is associated with variable lifestyle habits. Effective approaches to reduce heavy media use remain to be determined.

The "Haves, Have Some, and Have Nots:" a Latent Profile Analysis of Capacity, Quality, and Implementation in Community-Based Afterschool Programs.

Implementation of evidence-based practices is a critical factor in whether afterschool programs are successful in having a positive impact upon risk reduction and positive youth development. However, important prevention research reveals that contextual and organizational factors can affect implementation (Bradshaw & Pas in School Psychology Review, 40, 530-548, 2011) (Flaspohler et al., in American Journal of Community Psychology, 50(3-4), 271-281, 2012) (Gottfredson et al., Prevention Science, 3, 43-56, 2002) (McIntosh et al., Journal of Positive Behavior Interventions, 18(4), 209-218, 2016) (Payne in Prevention Science, 10, 151-167, 2009). Using a latent profile approach (LPA), this paper examines multiple organizational and neighborhood contextual factors that might affect the degree to which afterschool programs effectively implement evidence-based practices in the context of a cluster-randomized trial of the Paxis Good Behavior Game (PaxGBG). The Interactive Systems Framework (ISF) explores dimensions of capacity that might matter for prevention efforts. As expected, we found that well-resourced and high-quality programs performed well in terms of implementation (the Haves) and, in neighborhood contexts rich in racial-ethnic diversity. Yet, we found that some programs with less physical and material capacity (the Have Nots), demonstrated greater program quality (i.e., supportive adult and peer relationships, engagement, a sense of belonging) and implementation, relative to programs with better capacity (e.g., space, material resources, staffing, and leadership, the Have Somes). While capacity matters, intentional prevention initiatives that seek to promote evidence-based practices are helpful to sites in supporting organizations that might otherwise fail to provide quality programming for youth. This paper addresses a conundrum in prevention science, namely, how to make programming accessible to those who need it with a focus on organizational processes, program quality, and implementation of evidence-based practices.

Culturally Responsive Practices: Insights from a High-Quality Math Afterschool Program Serving Underprivileged Latinx Youth.

High-quality afterschool programs (ASPs) are opportunities to diversify the ways that Latinx youth from economically underprivileged communities experience STEM learning. Utilizing qualitative methods, based on the experiences and perspectives of low-income Latinx middle school participants of a math enrichment ASP in Southern California, we identified four culturally responsive practices: (1) the promotion of an inclusive, safe, and respectful program climate, (2) engaging in personal conversations, (3) facilitating opportunities for mutual and math learning across diverse cultures and perspectives, and (4) the promotion of math and a range of social-emotional skills across contexts. These practices helped youth feel more connected to the program, their peers, and program staff (college mentors); provided a platform for youth voice and contribution to the processes of teaching and learning; facilitated opportunities for skill development and practice across the different contexts of youth's lives; interrelated with Latinx cultural values; and helped to promote youth's engagement and math learning. Importantly, youth's relationships with their mentors was a significant aspect of their experiences and perceptions of these practices. We argue that culturally responsive practices are necessary to achieve high-quality programs and provide specific implications for how ASPs can implement them in the design and implementation of their programs.

What Happens After School? Linking Latino Adolescents' Activities and Exposure to Community Violence.

Although community violence and the deleterious behavioral and psychological consequences that are associated with exposure to community violence persist as serious public health concerns, identifying malleable factors that increase or decrease adolescents' risk of exposure to community violence remains a significant gap in our knowledge base. This longitudinal study addresses this research gap by investigating adolescents' endorsement of familismo values and participation in three types of after-school activities, specifically home-, school-, and community-based activities, as potential precursors to adolescents' risk for experiencing community violence. The sample consists of 416 Latino high school students (53% female) with a mean age of 15.5 years (SD = 1.0) and with 85% qualifying for free and reduced school lunch. Cross-sectional results demonstrated that adolescents' endorsement of the Latino cultural value of familismo was associated with lower rates of personal victimization. The frequency of non-structured community-based activities and part-time work were concurrently associated with higher rates of witnessing community violence and being personally victimized by violence. Only the frequency of non-structured community-based activities was related to witnessing more community violence and greater victimization one year later while controlling for prior exposure to violence. These findings underscore the importance of providing structured, well supervised after-school activities for low-income youth in high-risk neighborhoods.
