    Growth and maturation impact the development of young athletes’ physique and function, and may also influence their psychological and behavioral characteristics. Collective efficacy (CE), a psychological measure and potential mediator of sports performance, may be influenced by maturity status. However, there is scarce information available regarding young players' perceptions of CE and the relationship between the CE and the young athletes’ maturity status. Therefore, this study examined the perceived CE variation between young basketballplayers accounting for the influence of chronological age and biological maturity status. The sample included fifty-seven adolescent basketball players aged 9.5 to 15.5 years. Chronological age, estimated age at peak height velocity (PHV) and CE through the Portuguese version of the Collective Efficacy Questionnaire for Sports were considered. Bayesian multilevel modeling was used to examine the athletes’ perceived CE dimensions variation by age and maturity status. Overall, the adolescent basketball players’ perceived CE scores were high for all dimensions: ability (8.77±1.15); effort (9.20±1.03); persistence (8.87±1.18); preparation (8.96±1.08); unity (8.88±1.22). The variability estimates were very large, suggesting that the influence of maturity status on variation may be residual. There was no substantial relation between chronological age and the CE variation scores, although the results suggest that perceived variation was independent of chronological age variation and between players variation in maturity status. Given the small, localized sample investigated, further studies examining the relations of chronological age, maturity status, and perceived CE are suggested for better understanding the young athletes’ development in sport.

    Variation in perceived collective efficacy among adolescent basketball players across 4-month competitive season
    (Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2019) Soares, André L. A.; Mendes, Felipe G.; Miguel, Caio G.; Palheta, Carlos Ewerton; Milan, Fabrício J.; Collet, Carine; Nascimento, Juarez Vieira do; Carvalho, Humberto Moreira
    In sports, collective efficacy appears to be dependent on the interactions and organized dynamics between the players within the team. It is directly related to team ́s performance potential. This study examined the changes of perceived collective efficacy among young basketball players between 10 to 17 years across a 4-month competitive season, accounting for variation by age group. We explored the trends of perceived collective efficacy based on repeated measures across 4 months within the observed age range. Sixty-five adolescent male basketball players aged 13,7 (9,5 to 17,3) years at baseline were considered. Collective Efficacy Questionnaire for Sports (CEQS) was used to assess players ́ perception of collective efficacy. Players had high CEQS scores. Except for persistence, all CEQS factors did not vary by age group. No distinct trend of differences between age group was present. CEQS factors remained high on the second assessment, except for abilitywhere there was a systematic decrease of the scores at end-season. A negative trend was apparent forpersistence, preparationand unityas players were closer to late adolescence years. Overall, adolescent basketball players tend to have a positive perception of theirs and their teammates efficacy. Despite the small to trivial influence of exposure to training and competition during pubertal years observed, results suggest that approaching adult level may change negatively the efficacy perceptions of adolescent players. Hence, coaches and practitioners of youth basketball should consider that players ́ collective efficacy perceptions may vary as transient influences of pubertal growth and competitive level with age increase.
