Little is known about the influence of different types and sources of social support on physical activity in adolescents. The aim of this study was to analyse the association between physical activity and different types and sources of social support in adolescents. The sample consisted of 2,859 adolescents between 14–19 years of age in the city of João Pessoa, in Northeastern Brazil. Physical activity was measured with a questionnaire and social support from parents and friends using a 10-item scale five for each group (type of support: encouragement, joint participation, watching, inviting, positive comments and transportation). Multivariable analysis showed that the types of support provided by parents associated with physical activity in adolescents were encouragement for females (P < 0.001) and adolescents between 14–16 years of age (P = 0.003), and transportation (P = 0.014) and comments (P = 0.037) for males. The types of social support provided by friends were: joint participation in male adolescents (P < 0.001) and in these 17–19-year-olds (P < 0.001), and comments in both genders (males: P = 0.009; females: P < 0.001) and 14–16-year-olds (P < 0.001). We conclude that the type of social support associated with physical activity varies according to its source, as well as the gender and age of the adolescents. 相似文献

This article examines the nature of early adolescents' environmental involvement based on a study with 10–13‐year‐olds. Drawing from literal and metaphorical interviews, a visual survey and visual maps, the study points to the dimensions of environmental involvement: connectedness, engagement with the environment, questioning, belief in capacity, taking a stance and strategic action. Children's agency runs across the dimensions, as children intentionally and strategically figure their way through significant life influences, beliefs towards nature and age‐defined barriers. Of interest is what the sources of environmental involvement are, as well as how a child interacts and engages in situations and with resources at hand. Along with awakening to the natural environment, children are discovering themselves and carving a place in the world. 相似文献

This prospective study determined whether: (1) objective physical activity (PA) and sedentary (SED) time at 9 years was associated with cognition at 15 years, (2) cognition at 9 years was associated with PA and SED at 15 years, and (3) the change in PA and SED from 9 to 15 years was associated with the change in cognition. Cognitive performance was assessed from picture vocabulary, verbal analogy, passage comprehension, and applied problem tasks. Regression models were used to explore each aim while adjusting for covariates. Among the combined sample, SED (min· day?1) at 9 years was unrelated with cognitive performance at 15 years, whereas participating in ≥ 60 min· day?1 of moderate-to-vigorous PA (MVPA) at 9 years predicted lower cognitive scores at 15 years. In the reverse direction, cognitive performance at 9 years was unrelated with SED and MVPA (min· day?1) at 15 years. Over 6 years, increased SED (min· day?1) predicted lower improvement to verbal analogy scores (B = ?0.01, p = 0.028). In comparison, an increase (or relatively smaller decline) in MVPA (min· day?1) predicted greater improvement in applied problem scores (B = 0.06, p = 0.007). Contextual information regarding SED and MVPA behavior would help understand bi-directional associations of activity and cognition. 相似文献

The aim of this study was to provide initial evidence of validity and reliability of scores derived from the Activity Context in Youth Sport Questionnaire (ACYSQ), an instrument designed to offer a comprehensive assessment of the activities adolescents take part in during sport practices. Two studies were designed for the purposes of item development and selection, and to provide evidence of structural and criterion validity of ACYSQ scores, respectively (N = 334; M age = 14.93, SD = 1.76 years). Confirmatory factor analysis (CFA) supported the adequacy of a 20-item ACYSQ measurement model, which was invariant across gender, and comprised the following dimensions: (1) stimulation; (2) usefulness-value; (3) authenticity; (4) repetition-boredom; and (5) ineffectiveness. Internal consistency reliability estimates and composite reliability estimates for ACYSQ subscale scores ranged from 0.72 to 0.91. In regression analyses, stimulation predicted enjoyment and perceived competence, ineffectiveness was significantly associated with perceived competence and authenticity emerged as a predictor of commitment in sport. These findings indicate that the ACYSQ displays adequate psychometric properties and the use of the instrument may be useful for studying selected activity-based features of the practice environment and their motivational consequences in youth sport. 相似文献

AbstractThe 1950s saw a wave of depictions of threatening male working-class adolescents in English novels, films and cartoons. However, these texts must be contextualised not only as part of the well-documented 1950s moral panic about youth but in relation to the popularized psychological concepts of the ‘normal’ and ‘deviant’ child and the increasing implementation of progressive educational ideas that artificially limited working-class pupils’ horizons. This makes this period not only another reiteration of the perennial moral panics about the rising generation that Geoffrey Pearson has documented, but an emergence of a new way of conceptualizing youth. 相似文献

Investigating whether changing societal circumstances have altered the development of civic engagement, this study compared developmental changes from mid- to late adolescence (i.e., age 15–18) across two cohorts of representative Swiss samples (born in 1991, N = 1258, Mage T1 = 15.30, 54% female, 33% migration background representing diverse ethnicities; born in 2000, N = 930, Mage T1 = 15.32, 51% female; 33% migration background). Findings from latent multigroup models revealed similar levels in attitudes about social justice in both cohorts, remaining stable over time. Adolescents reported lower levels of political efficacy and informal helping in the cohort born in 2000. Both aspects slightly increased during adolescence. Informal helping had a steeper increase in the 1991 compared to the 2000 cohort, suggesting developmental differences between cohorts. 相似文献

The aim of the study was to investigate the relationships between attribution style and social, emotional and behavioural difficulties (SEBDs), and to explore differences in attribution tendencies between adolescents with and without SEBDs. In total, 72 adolescents attending a school in London were recruited; 27 were receiving support for SEBDs from the behaviour and education support team at their school and 45 were recruited from the main school population. Participants completed the Children’s Attribution Style Questionnaire and the Strengths and Difficulties Questionnaire. A multivariate analysis of variance revealed that adolescents with SEBDs had a more negative attribution style, made more stable attributions of negative events and reported fewer internal attributions of positive events than students without SEBDs. The findings highlight the importance of cognitive factors in providing a basis for interventions intending to address young people’s behaviour and cater for the heterogeneous nature of SEBDs. 相似文献
