Supporting physical activity adoption through recommender system technology: A pilot study.

We tested the potential for recommender system technology to provide personalized physical activity (PA) suggestions for inactive young adults with high bodyweight. We developed a recommender system using data from the 2017 Behavioral Risk Factor Surveillance System and assessed interest in using the system among 47 young adults (mean age = 23.0 years; 63.4% female; 65.0% White; mean BMI = 29.4). Eleven of these participants (mean age = 23.6 years; 90.9% female, 63.6% White; average BMI = 28.5) also received a PA recommendation and a follow-up interview. Approximately half of the survey participants were willing to use the recommender system, and participants interested in the recommender system differed from those unwilling to try the system (e.g., more likely to be female, worse self-perceived health). Furthermore, eight of the 11 interviewees tried the PA recommended to them, but had mixed reviews of the system's accuracy. Although our recommender system requires improvements, such systems have promise for supporting PA adoption.

Improving reflective evaluations of sport through repeated experiences of fun-rationale, design, feasibility, and acceptability of the PlayFit Youth Sport Program.

INTRODUCTION: Adolescents who drop out of sport often report that it had become less 'fun' and 'enjoyable' over time. Although preadolescent sport typically emphasizes experiences of fun, emphases on competition and elite performance often dominate during adolescence. We theorized that adherence to adolescent sport might be improved if the overarching goal were to maximize repeated experiences of fun during sport and, subsequently, increase reflective evaluations of sport enjoyment. To that end, this manuscript reports on the rationale and design of the PlayFit Youth Sport Program (PYSP), as well as its preliminary feasibility and acceptability. The main objectives were to evaluate the feasibility of recruitment strategies and data collection procedures and the acceptability of the intervention. SETTING: An outdoor, multipurpose grass field at a south-central Pennsylvania middle school. METHODS: A mixed-methods, single-arm feasibility trial lasting for 8 weeks (August-October 2021) offered 3-times per week for 1-h per session. The equipment, ruleset, and psychosocial environment of the PYSP sport games were modified to reduce several of the constraints theorized to impair experiences of fun during sport and hamper reflective evaluations of enjoyment afterward. RESULTS: Eleven healthy, but sedentary adolescents in grades 5-7 completed the program. The median number of sessions attended (of 16 possible) was 12 (range = 6-13). Post-intervention, 9/10 respondents indicated that they 'looked forward' to the PYSP, 8/10 would recommend it to a friend, and 8/10 were interested in continuing the program. Ten of 11 participant guardians expressed interest in reenrolling their children if the PYSP were offered again. Some changes recommended were to improve recruitment via advertising the positive aspects of the program and "word of mouth" techniques, offering the program immediately following the school day, having contingencies for inclement weather, and minor changes to the sport equipment to improve the experience among the population the PYSP intends to attract. CONCLUSIONS: The adjustments recommended in this preliminary work could be used to further refine the PYSP. A future efficacy trial could explore whether the PYSP may reduce attrition for adolescents who experience existing sport programs negatively by offering an alternative that better matches their unique needs and preferences.

A multi-dimensional measure of pro-environmental behavior for use across populations with varying levels of environmental involvement in the United States.

Researchers continue to explore ways to understand and promote pro-environmental behavior (PEB) amongst various populations. Despite this shared goal, much debate exists on the operationalization and the dimensionality of PEB and how it is measured. This piecemeal approach to measurement has limited the ability to draw conclusions across studies. We address limitations associated with previous measures of PEB by developing a multi-dimensional scale that is validated across both a general population of individuals residing in the United States as well as a group of individuals associated with a pro-environmental organization. Exploratory and confirmatory factor analyses and reliability estimation were conducted for the developed measure across these two populations. Measurement invariance testing was also utilized to assess the psychometric stability of the scale across the two groups. Results indicated an 11 item scale was best fitting with two sub-scales: private and public behaviors. Implications for research and practice are discussed.

"Pick your team wisely": A case study of a long-standing research-practice partnership.

Research-practice partnerships (RPP) provide opportunities to connect researchers, practitioners, and/or community development professionals in meaningful ways, thereby improving the quality of research, evaluation, and practice in communities. Yet, there is still much to learn about how successful partnerships between researchers and practitioners develop. Historically, research on this topic has emphasized challenges that prevent RPP from developing to their highest potential, with limited information available on ways to promote RPP and how to ensure RPP are mutually beneficial for participants. However, research on partnerships more generally, such as multisector partnerships, can contribute meaningfully to the RPP field. We present an in-depth case study on a successful, long-term partnership. In this study, we pull from the broader partnership literature to explore contexts that are likely to promote partnerships, as well as the activities that can strengthen RPP. Findings focus on addressing ways to promote RPP and highlight the importance of preexisting factors, such as a culture that values both researcher and practitioner expertise, history, and chemistry between partners. Additionally, non-professional space and time, productive disagreements, clear but evolving roles, and shared power were found to strengthen collaboration within the partnership. Specific advice for anyone considering joining an RPP is also discussed.

When American Adults Do Move, How Do They Do So? Trends in Physical Activity Intensity, Type, and Modality: 1988-2017.

BACKGROUND: Few Americans accumulate enough physical activity (PA) to realize its benefits. Understanding how and why individuals use their discretionary time for different forms of PA could help identify and rectify issues that drive individuals away from certain physical activities, and leverage successful strategies to increase participation in others. METHODS: The authors analyzed approximately 30 years of changes in PA behavior by intensity, type, and mode, using data from the Behavioral Risk Factor Surveillance System. RESULTS: Since 1988, the proportions of adults most frequently engaging in exercise, sport, or lifestyle physical activity have changed noticeably. The most apparent changes from 1988 to 2017 were the proportions most frequently engaging in Exercise and Sport. In addition, the proportion of time reportedly spent in vigorous-intensity PA decreased over time, particularly among male respondents. Moreover, the proportion of Americans reporting an "Other" PA mode increased substantially, suggesting a growing need for a greater variety of easily accessible options for adult PA. CONCLUSIONS: Over time, a smaller proportion of American adults reported participating in sport and exercise modalities and reported engaging more frequently in low-intensity physical activities.

Adolescent Sport Participation and Symptoms of Anxiety and Depression: A Systematic Review and Meta-Analysis.

Sport may protect against symptoms of mental disorders that are increasingly prevalent among adolescents. This systematic review explores the relationship between adolescent organized sport participation and self-reported symptoms of anxiety and depression. From 9,955 records screened, 29 unique articles were selected that included 61 effect sizes and 122,056 participants. Effects were clustered into four categories based on the operationalization of sport involvement: absence or presence of involvement, frequency of involvement, volume of involvement, and duration of participation. Results from the random-effects meta-analyses indicated that symptoms of anxiety and depression were significantly lower among sport-involved adolescents than in those not involved in sport, although this effect size was small in magnitude. Meta-regression was used to identify how age and sex explained heterogeneity in effects. Although these results do not signify a causal effect, they do support theorizing that sport participation during adolescence may be a protective environment against anxiety and depressive symptoms.

Required Health and Wellness Courses: Associations With College Student Physical Activity Behavior and Attitudes.

OBJECTIVE: To assess the extent to which college student physical activity behaviors and attitudes are associated with enrollment in required, but self-selected, health and wellness courses. PARTICIPANTS: Data were analyzed from 1473 undergraduate students (60% women) taking health and wellness courses at a large northeastern university. METHODS: Demographic characteristics and activity levels at the time of course enrollment were assessed in relation to course selection and activity levels after course completion. One-way analysis of variance tests were used to assess the differences in the characteristics of students enrolling in different types of health and wellness courses, and paired samples t tests were used to assess the differences in physical activity and related attitudes from the time of enrollment to the end of the semester. RESULTS: Course selection was predicted by demographic characteristics and precourse activity levels. Overall, no significant change in activity levels was observed over the course of one semester, although some effects were observed within certain types of activities. CONCLUSIONS: When given the option, college students appear to select health and wellness courses that match their current activity levels. These courses do not significantly change the average student's behavior or attitudes about physical activity.

Peer motivational climate and character development: Testing a practitioner-developed youth sport model.

Youth sport is a key developmental context for many reasons, including the opportunities it provides for building relationships with peers and its potential to support character development. Peers can influence adolescent sport experiences and shape their motivations, and different peer motivational climates may differentially support athlete character. Established models identify different dimensions of peer motivational climate, yet these models do not describe how aspects of peer climate may align with character. We therefore assess profiles of peer motivational climate in relation to a multi-dimensional practitioner-developed theoretical model for character development through sport. Participants were 655 adolescent athletes from the greater Boston area, in the United States. Athletes perceiving a mastery-involved peer climate, even with high intra-team competition, were most likely to exhibit positive character attributes at the three levels of character assessed: themselves, their teammates, and the game. This study also demonstrates the utility of practitioner-developed models for adolescent research.

Adolescent Athletic Participation Patterns and Self-Perceived Competence: Associations With Later Participation, Depressive Symptoms, and Health.

Physical activity is important for well-being across the life span. However, links between patterns of adolescent activity, competence perceptions, and young adult outcomes are underexplored. We used data from seven waves of the 4-H Study of Positive Youth Development (N = 5,961) to assess patterns of adolescent athletic participation, whether these patterns were associated with self-perceived athletic competence and young adult physical activity, depressive symptoms, and health, and associations between changes in participation across adolescence and young adult outcomes. Competence perceptions were associated with increased participation, and more active adolescents had higher rates of adult athletic activity, with links to better health and fewer depressive symptoms. We discuss results in light of the importance of using person-centered analyses to understand active lifestyles.

Activity involvement as an ecological asset: profiles of participation and youth outcomes.

Prior research has demonstrated that participation in out-of-school time activities is associated with positive and healthy development among adolescents. However, fewer studies have examined how trajectories of participation across multiple activities can impact developmental outcomes. Using data from Wave 3 (approximately Grade 7) through Wave 8 (approximately Grade 12) of the 4-H Study of Positive Youth Development, this study examined patterns of breadth in out-of-school time participation in activities and associated outcomes in positive youth development (PYD), Contribution to self and community, risk behaviors, and depressive symptoms. We assessed 927 students (on average across waves, 65.4% female) from a relatively racially and ethnically homogeneous sample (about 74% European American, across waves) with a mean age in Wave 3 of 12.98 years (SD = 0.52). The results indicated that high likelihood of participation in activities was consistently associated with fewer negative outcomes and higher scores on PYD and Contribution, as compared to low likelihood of participation in activities. Changes in the breadth of participation (in particular, moving from a high to a low likelihood of participation) were associated with increased substance use, depressive symptoms, and risk behaviors. Limitations of the current study, implications for future research, and applications to youth programs are discussed.

Understanding entrepreneurial intent in late adolescence: the role of intentional self-regulation and innovation.

Entrepreneurship represents a form of adaptive developmental regulation through which both entrepreneurs and their ecologies benefit. We describe entrepreneurship from the perspective of relational developmental systems theory, and examine the joint role of personal attributes, contextual attributes, and characteristics of person-context relationships in predicting entrepreneurial intent in a sample 3,461 college students enrolled in colleges and universities in the United States (60 % female; 61 % European American). Specifically, we tested whether personal characteristics (i.e., gender, intentional self-regulation skills, innovation orientation) and contextual factors (i.e., entrepreneurial parents) predicted college students' intentions to pursue an entrepreneurial career. Our findings suggest that self-regulation, innovation orientation, and having entrepreneurial role models (i.e., parents) predict entrepreneurial intent. Limitations and future directions for the study of youth entrepreneurship are discussed.

Positive movement experiences: approaching the study of athletic participation, exercise, and leisure activity through relational developmental systems theory and the concept of embodiment.

Exercise and athletic participation are widely recognized as important aspects of healthy lifestyles and human development; yet most of the research on youth athletic participation, exercise, and leisure activity has not yet adopted a theoretical framework useful for understanding the development of individual engagement with these movement contexts. In order to gain an adequate understanding of the developmental experiences of involvement in movement contexts, understanding the role of the active individual and the mutually influential relations between individual and context are important. In this chapter, we present a new approach to the study of involvement in movement contexts, using relational developmental systems theory and the concept of embodiment to forward the idea of positive movement experiences (PMEs). The concept of PMEs may facilitate better understanding of involvement in movement contexts as a fundamental component of human life in general, and of youth development in particular.

Youth development program participation and intentional self-regulation skills: contextual and individual bases of pathways to positive youth development.

The present research used data from Grades 8, 9, and 10 of the 4-H Study of Positive Youth Development, a longitudinal study involving U.S. adolescents, in order to better elucidate the process through which the strengths of youth and the ecological resources promoting healthy development (such as out-of-school-time programs) may contribute to thriving. We examined the relationship between adolescents' self-regulation skills (selection, optimization, and compensation) and their participation in youth development (YD) programs across Grades 8 and 9 in predicting Grade 10 PYD and Contribution. Results indicated that while self-regulation skills alone predicted PYD, self regulation and YD program participation both predicted Contribution. In addition, Grade 8 YD participation positively predicted Grade 9 self regulation, which, in turn, predicted Grade 10 PYD and Contribution. We discuss how the alignment of youth strengths and resources within the environment may promote positive youth development.

The role of ecological assets in positive and problematic developmental trajectories.

Two theoretical perspectives have been proposed to describe, explain, and intervene in adolescent development - prevention science and positive youth development (PYD). An integrative model bridging these two perspectives posits that it is important to assess the extent to which the same, similar, or complementary mechanisms may be responsible for preventing problem behavior and promoting PYD. Therefore, using data from the 4-H Study of PYD, the present study examines the role of assets in the family, school, and neighborhood in differentiating trajectories of goal-optimization and delinquency in a sample of 626 youth (50.9% female) from Grades 5 to 11. The results indicated that collective activity in the family best predicted membership for the five goal-optimization trajectories while school-based assets differentiated the four delinquency trajectories that were identified. The findings suggest that multidimensional approaches may be most effective to promote PYD and prevent problem behaviors.
