Relationship with Adults in Organized Sports and Non-Sports Activities and Links with Psychological Adjustment in Adolescence: A 6-Year Longitudinal Study.

Relationships with adults in organized activities play a crucial role in the positive outcomes associated with these experiences, yet little is known about how these relationships evolve throughout adolescence or how they are differentially associated with mental health. Important distinctions could also be made regarding activity types. The sample consisted of 292 participants (58% female; M age = 12.

Associations between parental civic engagement, negative beliefs toward civic engagement and youths' future civic attitudes and behaviors.

Introduction: Civic engagement (CE) in adolescence is associated with a higher level of engagement in adulthood and is reported to be beneficial to youth's development and societal well-being. Parents are among the most influential factors in adolescents' lives. This study examined the associations between parents' own civic participation, their negative beliefs toward youth CE and their child's future CE.

A sequential model of the contribution of preschool fluid and crystallized cognitive abilities to later school achievement.

The present study documented in two distinct population-based samples the contribution of preschool fluid and crystallized cognitive abilities to school achievement in primary school and examined the mediating role of crystallized abilities in this sequence of predictive associations. In both samples, participants were assessed on the same cognitive abilities at 63 months (sample 1, n = 1072), and at 41 and 73 months (sample 2, n = 1583), and then with respect to their school achievement from grade 1 (7 years) to grade 6 (12 years). Preschool crystallized abilities were found to play a key role in predicting school achievement.

Organized activities in adolescence and pro-environmental behaviors in adulthood: The mediating role of pro-environmental attitudes.

Introduction: Organized activities practiced in adolescence are known to foster positive development, including active citizenship. Active citizenship encompasses a wide range of behaviors, one of them being pro-environmental behaviors. Few studies focused on the developmental factors that may predict these behaviors in adults, despite their crucial role in counteracting the current climate crisis.

School-based extracurricular activity involvement and high school dropout among at-risk students: Consistency matters.

Encouraging involvement in school-based extracurricular activities (ECA) may be important for preventing high school dropout. However, the potential of these activities remains underexploited, perhaps because studies linking ECA involvement and dropout are rare and based on decades-old data. Previous studies also ignore key parameters of student involvement.

Peer victimization in school and mental and physical health problems in young adulthood: Examining the role of revictimization at the workplace.

Peer victimization during the school years can impair victims' mental and physical health even in adulthood. Moreover, some victims of school bullying may also experience revictimization at work as adults. Later revictimization at work may thus at least partly explain (i.

A detailed examination of the longitudinal associations between individual and team sports and alcohol use.

This study examined the longitudinal associations between participation in individual and team sports and indicators of alcohol use during the high school years and beyond. A total of 310 youths were surveyed over six waves of data collection (ages 12, 14 to 17, and 19). Participation in individual and team sports was measured through phone interviews, whereas frequency of alcohol use, frequency of intoxication, and problematic alcohol use were self-reported.

Motivation towards extracurricular activities and motivation at school: A test of the generalization effect hypothesis.

Participation in extracurricular activities is a promising avenue for enhancing students' school motivation. Using self-determination theory (Deci & Ryan, 2000), the goal of this study was to test a serial multiple mediator model. In this model, students' perceptions of autonomy support from their extracurricular activity leader predicted their activity-based intrinsic and identified regulations.

Organized Activities During High School and Adjustment One Year Post High School: Identifying Social Mediators.

This longitudinal study investigated social capital as a way through which youths' organized activities promote their future adjustment. Specifically, we examined social mediators of the associations between intensity, duration, and breadth of participation from age 14 to 17 and adjustment at age 18. Two social mediators were tested: support from the activity leader and social integration into the activity peer group.

Friendships with co-participants in organized activities: prevalence, quality, friends' characteristics, and associations with adolescents' adjustment.

The goal of this study was to provide an in-depth examination of friendships within organized activities. The prevalence of friendships with co-participants, their quality and characteristics, and their associations with adjustment were investigated. A sample of 281 (60% girls) 8th grade adolescents reported their friendships, activities, and adjustment.

Other-sex friendships as a mediator between parental monitoring and substance use in girls and boys.

Previous research examining relationships between parental monitoring, friendship networks, and substance use did not take into account the gender of both the adolescent and the friends. The goal of this study was to test a mediation model in which having other-sex friends during mid-adolescence mediates the relationships between parental monitoring in early adolescence and substance use during late adolescence. We hypothesized that mediation would be observed for girls but not for boys.

Quality at the point of service: profiles of practice in after-school settings.

A unique observational data set was used to explore quality at the point of service in after-school programs. Staff practices in after-school settings were represented on a series of unidimensional scales closely indexed to staff behavior. In order to account for heterogeneity of staff performances, pattern-centered methods were used to construct profiles of common staff practices.

Intensity and breadth of participation in organized activities during the adolescent years: multiple associations with youth outcomes.

The goal of this study was to examine initial levels and rates of change in the intensity and breadth of participation in organized activities during the adolescent years, and how these participation practices were related to youth outcomes in later adolescence. The main objectives were (a) to examine growth curves of intensity and breadth of participation from Grades 7 through 11 and their interrelations, and (b) to test the associations between these dimensions of participation and academic orientation, risky behaviors, internalizing problems, and civic development in Grade 11. A homogenous sample of 299 youth (mean age = 13.
