Examined the effects of the normative school transition to senior high school (n=330) on the self-system and perceived school and peer social contexts of poor, black (n=83), European American (n=115), Latino (n=105), and Asian American (n=27) youth in the public school systems of three Eastern urban cities. The only negative effect of the school transition on
the self-system was a decline in grade point average (GPA). Concurrently, the school transition was perceived to be associated
with changes in the school and peer contexts. Across the transition, students reported increased disengagement from school
(i.e., increased social support and extracurricular involvement) and increased engagement with peers (i.e., decreased daily
hassles and increased involvement). These changes in the school and peer microsystems, like the changes in the self-system,
were also common across race/ethnicity and gender. In addition, transition-associated school changes, and in particular changes
in daily academic demands/hassles and involvement in school activities, were associated with changes in the academic dimensions
of the self-system (i.e., academic efficacy expectations and GPA). Results and implications for preventive intervention are
discussed within a developmental mismatch framework.

National athlete development models often give little consideration to the multiple ways in which adults might participate in sport (i.e., recreationally or competitively, through sampling or specialization), or their trajectories into specific patterns of adult sport participation. Using adult swimmers' current and retrospective (youth swimming) data, the purpose of this study was threefold: a) to identify profiles of masters swimmers based on participation characteristics, b) to explore demographic differences between profiles, and c) to retrospectively examine these profiles for meaningful associations with youth swimming experiences. Survey data were collected from 205 Canadian masters swimmers with previous competitive youth swimming experience (M age = 44.4, range = 18–85; 60% women, 40% men). Two-step clustering analysis of masters' current swimming participation resulted in three distinct profiles: 1) “low-competitive specializers,” 2) “high-competitive specializers,” and 3) “samplers.” These profiles were not significantly associated with any demographic variables in adulthood, nor did they differ in terms of youth swimming experiences and time to transition into masters swimming. The remarkable homogeneity of social-demographic variables suggests that further work is needed to make masters swimming more inviting to diverse adult populations. Retrospective data revealed disengagement and later re-engagement in swimming that was consistent across masters profiles. Implications of these findings for coaches and programmers, as well as the need to account for adults' potentially complex re-entries into sport after time away, are discussed. 相似文献
The conceptualization of stress‐responsive physiological systems as operating in an integrated manner is evident in several theoretical models of cross‐system functioning. However, limited empirical research has modeled the complexity of multisystem activity. Moreover few studies have explored developmentally regulated changes in multisystem activity during early childhood when plasticity is particularly pronounced. The current study used latent profile analysis (LPA) to evaluate multisystem activity during fall and spring of children's transition to kindergarten in three biological systems: the parasympathetic nervous system (PNS), sympathetic nervous system (SNS), and hypothalamic pituitary adrenal (HPA) axis. Latent transition analysis (LTA) was then used to examine the stability of profile classification across time. Across both timepoints, three distinct profiles of multisystem activity emerged. One profile was characterized by heightened HPA axis activity (HPA Axis Responders), a second profile was characterized by moderate, typically adaptive patterns across the PNS, SNS, and HPA axis (Active Copers/Mobilizers), and a third profile was characterized by heightened baseline activity, particularly in the PNS and SNS (Anticipatory Arousal/ANS Responders). LTA of fall‐to‐spring profile classifications indicated higher probabilities that children remained in the same profile over time compared to probabilities of profile changes, suggesting stability in certain patterns of cross‐system responsivity. Patterns of profile stability and change were associated with socioemotional outcomes at the end of the school year. Findings highlight the utility of LPA and LTA to detect meaningful patterns of complex multisystem physiological activity across three systems and their associations with early adjustment during an important developmental transition. 相似文献
Objective: We examine concurrent and longitudinal associations between sleep duration (SD) and body mass index (BMI) from adolescence to young adulthood, controlling for physical activity and internalising symptoms. Sex and age group differences (early adolescent group ages 12–15 years and late adolescent group ages 16–18 years) are examined.
Design: A randomly selected community-based sample of youth (N = 662; 48.3% males) were surveyed biannually from 2003 (T1) to 2014 (T6).
Results: We found sex and age group differences for the concurrent and longitudinal associations between SD and BMI. For males, shorter SD at baseline was concurrently related to higher BMI. For females, shorter SD at baseline was associated with longitudinal increases in BMI, for the late adolescent group only.
Conclusion: Findings show that the association between SD and BMI, previously shown in childhood, continues to be significant in adolescence and young adulthood. Developmentally appropriate and sex-specific strategies for motivating and supporting healthy sleep habits in adolescence that may help to prevent weight gain into young adulthood are discussed. 相似文献
ObjectivesThis study used the Scheme of Change for Sport Psychology Practice (SCSPP; Samuel & Tenenbaum, 2011a) to examine athletes' and coaches' personal characteristics, perceptions of, coping with, and perceived outcome of the London 2012 Olympic Games (OGs). We also contrasted several sub-groups (e.g., Olympic and Paralympic athletes) in certain variables, and examined the decision-making and support systems involved in the OGs change process.Design and methodsA cross-sectional and retrospective design was used. Israeli Olympic and Paralympic athletes and coaches (N = 61) completed measures of change-event experiences (Samuel & Tenenbaum, 2011b) and athletic/coaching identity (AI/CI; Brewer & Cornelius, 2001) two years after the London 2012 OGs.ResultsOlympic athletes trained more, and had higher motivation and AI than Paralympic athletes. The OGs were perceived as a significant and positive change-event in the participants' careers. AI/CI was associated with the perceived significance of the OGs. At the time of Olympic qualification, the participants tended either to ignore this change-event or cope with it independently. Most participants reported making a decision to change related to adjustment and coping. Professional support was mainly available prior to and during the OGs. During this experience the participants did not consider using sport psychology services, but retrospectively, valued the usefulness of this support. Athletes' motivation after the OGs was predicted from their satisfaction of coping, and their perceived outcome of this change-event was predicted from their satisfaction of competition results.ConclusionsPsychological support must be provided as part of the Olympic cycle, especially in promoting a decision to change. Maintaining realistic expectations may be critical for facilitating a positive perception of this change-event. 相似文献
Development of career goals that are adapted to self and opportunities is a central component of adolescent career preparation. The present longitudinal study (conducted throughout the eighth grade with three assessment points) investigated how 330 Swiss adolescents simultaneously adapt career goals to interests, scholastic achievement and environmental opportunities. Results demonstrated that students increasingly adapt their goals to the environment. Mean adaptation to environment related positively to degree of adaption to interests and achievement. Increased adaptation to environment over time related to increased adaptation to achievement but to decreased adaptation to interests. Gender, attended school type and nationality moderated adaptation processes. Structurally disadvantaged students (girls, lower requirements school track, immigrant students) reported more conflict in aligning adaptation to environment with adaptation to interests. 相似文献
This study investigated the 6-year stability and predictive validity of adolescent psychopathy features during the transition to young adulthood. It represents one of the longest outcome studies of youth psychopathy to date, and therefore addresses a primary criticism of the research area (i.e., lack of demonstrated associations between child and adult psychopathy features). Recruited participants were 475 males enrolled in the Minnesota Twin and Family Study who had completed a research-based measure of psychopathy features consisting of separate emotional detachment (or affective) and antisocial tendencies (or behavioral) subscales. These psychopathy features and various externalizing symptoms (i.e., conduct problems, impulsivity, and substance use disorder) were assessed through rating scales and structured diagnostic interview at an intake assessment (ages 16-18) and 6-year follow-up. Consistent with prediction, adolescent psychopathy features displayed moderate stability across the transition from adolescence to adulthood [intraclass correlation coefficients (ICCs) = 0.40-0.41]. The antisocial tendencies subscale was uniquely related to most externalizing symptoms both in adolescence and in adulthood, whereas the emotional detachment subscale showed appropriate discriminant validity in its lack of association with externalizing symptoms. These findings suggest that psychopathy features are relatively stable from adolescence to adulthood and provide possible insights into the development and maintenance of externalizing difficulties during the adult transition. 相似文献
