The present study explored how the organizational cultural experiences of elite youth footballers shaped their identity development and behavior. The first author occupied the position of sport psychology practitioner-researcher within 1 professional football club over 3 years. Traditional ethnographic research methods were employed, including observations, field notes, reflections, and informal interviews. A cultural sport psychology perspective on identity as a social construction and research on the cultural characteristics of professional football were used as frameworks to make sense of the data. Despite the introduction of the Elite Player Performance Plan in 2012, the traditional masculine culture of professional football dominated the studied club. Creative nonfiction vignettes revealed that youth players were encouraged to develop their self-stories focused on a single-minded dedication to professional football. The limited identity-related resources offered at both club and cultural level are detrimental for players in terms of their well-being and long-term psychological development. From the results of this study, we suggest that future sports psychology practice within professional football may best be delivered at an organizational level. However, for sport psychologists to be effective in this role, they must develop an understanding of the subcultural features and characteristics of the organization. In line with this, there would be great value in introducing a focus on organizational culture within sport psychology professional training and education routes.Lay Summary: This paper explores the impact of the professional football culture on the psychological development of elite youth footballers. From the findings we suggest that sport psychology should be delivered at an organisational level. 相似文献

AbstractDrop out is a typical issue in longitudinal studies. When the missingness is non-ignorable, inference based on the observed data only may be biased. This paper is motivated by the Leiden 85+ study, a longitudinal study conducted to analyze the dynamics of cognitive functioning in the elderly. We account for dependence between longitudinal responses from the same subject using time-varying random effects associated with a heterogeneous hidden Markov chain. As several participants in the study drop out prematurely, we introduce a further random effect model to describe the missing data mechanism. The potential dependence between the random effects in the two equations (and, therefore, between the two processes) is introduced through a joint distribution specified via a latent structure approach. The application of the proposal to data from the Leiden 85+ study shows its effectiveness in modeling heterogeneous longitudinal patterns, possibly influenced by the missing data process. Results from a sensitivity analysis show the robustness of the estimates with respect to misspecification of the missing data mechanism. A simulation study provides evidence for the reliability of the inferential conclusions drawn from the analysis of the Leiden 85+ data. 相似文献

There are a large number of studies demonstrating that visuospatial working memory (VSWM) involves different subcomponents, but there is no agreement on the identity of these dimensions. The present study attempts to combine different theoretical accounts by measuring VSWM. A battery composed of 13 tests was used to assess working memory and, in particular, the hypothesized mechanisms involved in the tasks, that is, active processing and passive recall of visual versus sequential‐spatial versus simultaneous‐spatial versus verbal tasks. The battery consisted of a number of tests already used in previous studies and new tests developed to examine specific components of working memory. We analysed the psychometric characteristics of the tests, the correlations amongst measured variables and estimated the measured variables with structural equation modelling in children attending third and fourth grades. Results revealed that the best model was composed of a specific verbal factor, three visuospatial passive factors (sequential‐spatial, simultaneous‐spatial, and visual) and one visuospatial active factor. 相似文献
