The main purpose of this work was to examine the relationships between the sport sense of community, athlete burnout, engagement, and motivation in adolescent athletes, adopting a longitudinal perspective, and using both person- and variable-centred approaches. A total of 250 adolescent athletes were involved in the study. Athletes' perceptions of burnout, engagement and motivation significantly differed across two different clusters: high and low sport sense of community profiles. Consistent with our hypothesis, sport sense of community dimensions (i.e., satisfaction of needs and influence) negatively predicted athlete burnout and controlled motivation, and positively predicted engagement and autonomous motivation six months later.

Lay Summary: Athlete burnout is associated with negative consequences for athletes’ well-being, whereas engagement reflects a positive state. The sport sense of community refers to the athletes’ relationship with their sport environment. In this study, we provided preliminary evidence of the protective role of the sport sense of community on athlete burnout.  相似文献

Previous work by our group has shown that infant emotional vitality (EV), the lively expression of shared emotion both positive and negative, predicts cognitive and language abilities in toddlerhood. Specifically, infants who demonstrated a pattern of high emotional expression combined with high bids to their caregivers, fared significantly better on the Bayley II and Preschool Language Scales (PLS‐3) at 2 years of age than infants who showed both low expression and low bids to mother. That study was conducted on a large, low‐income, ethnically diverse sample. The current study was undertaken with a smaller but demographically similar sample as an effort to demonstrate the value of EV as a construct and to provide additional information about its links with later developmental outcomes. Replication that included a variation in the age at which EV was assessed provides support for the generalizability of the construct. In addition, this study examined EV's effects further into childhood than did the original study in order to insure they are not limited to a brief window in toddlerhood. The results indicate that over and above maternal psychological resources, EV expressed during positive/joyful and frustrating circumstances in 8‐month‐olds accounted for significant portions of variance in expressive language at 30 months and cognitive‐developmental assessments at 24 and 36 months. This study supports EV as an important relational‐emotional behaviour that increases experiences that optimize developmental outcomes. Successful replication suggests that EV holds promise as a construct with clinical utility for early interventions attempting to improve developmental outcomes in children from poor families.

Primary prevention aims at reducing the incidence of a disorder. The first step in primary prevention involves documenting the magnitude of the problem and identifying risk factors. Consistent with primary prevention practices, we review the national and international epidemiological data on suicide mortality and then discuss the implications these data hold for primary prevention. Our approach is novel because we systematically examine the suicide epidemiology data by gender and culture. Suicide mortality appears to be highest among individuals (e.g., young adult married females in some Papua New Guinea regions; older adult, isolated, White males in the United States) for whom such behavior is culturally sanctioned. Thus, an important target for primary prevention may be local cultures of gender and suicide.  相似文献
