RESUMO

In the present research, we introduce and validate a single-item measure of identity leadership-the visual identity leadership scale (VILS). The VILS uses Venn diagrams of sets of overlapping circles to denote different degrees of alignment between a leader's characteristics and behaviours and a group's values and goals. Key advantages of the VILS over other existing multi-item scales are that it provides a holistic assessment of identity leadership, is short, and can be adapted to address novel research questions that are impractical to address with existing scales (e.g. in diary studies, assessing multiple comparisons of many leaders or groups). Data from three studies (conducted in India, the United States and Germany) provide evidence of the VILS' construct reliability and validity. Results also showcase the instrument's capacity to be adapted to assess variations of identity leadership-for example, by assessing a leader's convergence with descriptive and ideal notions of collective self (i.e. with 'who we are' and 'who we want to be'). We discuss the value of including the VILS in the toolbox that researchers and practitioners can utilize to expand our understanding of identity processes in leadership and group behaviour.

RESUMO

The social identity approach to leadership posits that leaders' effectiveness depends on their ability to represent, advance, create, and embed a shared sense of social identity among their followers. Although significant progress has been made in investigating the benefits of identity leadership in adult sports, research in youth sports is still in its infancy. One reason is the lack of a youth-centric inventory that adequately measures identity leadership in this population. To bridge this gap, we developed and validated a long (16 items) and short (5 items) version of the Identity Leadership Inventory for Youth Sport (ILI-Y or ILI-Y-Short-Form) through five studies conducted in three phases of research. Data were primarily collected in football in the United Kingdom, involving a total of 1096 participants. Results of Phase I of this study provided little to no evidence that the ILI - originally developed for adults - was understandable (Study 1) and had factor validity and internal consistency (Study 2) in a sample of youth athletes. Therefore, in Phase II, the ILI was revised, leading to the development of the ILI-Y, which was understandable for youth athletes (Study 3). Results from Phase II (Study 4) also indicated that the ILI-Y exhibited a unidimensional factor structure, which was subsequently confirmed in Phase III (Study 5). This last phase offered additional evidence for the discriminant, criterion, and incremental validity of the ILI-Y and its short form, along with their measurement invariance across genders and age groups, and internal consistency. This study provides sports psychology researchers and practitioners with a valid measure to assess identity leadership in youth sports.

RESUMO

Background: Primary sclerosing cholangitis (PSC) is a chronic liver disease marked by inflammation of the bile ducts and results in the development of strictures and fibrosis. A robust clinical correlation exists between PSC and inflammatory bowel disease (IBD). At present, published data are controversial, and it is yet unclear whether IBD drives or attenuates PSC. Methods: Mdr2-deficient mice or DDC-fed mice were used as experimental models for sclerosing cholangitis. Additionally, colitis was induced in mice with experimental sclerosing cholangitis, either through infection with Citrobacter rodentium or by feeding with DSS. Lastly, fibrosis levels were determined through FibroScan analysis in people with PSC and PSC-IBD. Results: Using two distinct experimental models of colitis and two models of sclerosing cholangitis, we found that colitis does not aggravate liver pathology, but rather reduces liver inflammation and liver fibrosis. Likewise, people with PSC-IBD have decreased liver fibrosis compared to those with PSC alone. Conclusions: We found evidence that intestinal inflammation attenuates liver pathology. This study serves as a basis for further research on the pathogenesis of PSC and PSC-IBD, as well as the molecular mechanism responsible for the protective effect of IBD on PSC development. This study could lead to the discovery of novel therapeutic targets for PSC.

RESUMO

Retirement is one of the most impactful career transitions athletes face. Researchers recognise the role that athletic identity plays in this, but analysis of identity content and change processes is limited. Addressing this gap, we conducted a qualitative study exploring the experience of identity change in 21 competitive and successful elite athletes who had retired from sport. All participated in a one-session psychoeducational program that explored the challenges of transitioning out of sport before being interviewed about their understanding of identity in sport, and their experiences negotiating identity loss and change in retirement. Using reflexive thematic analysis, we identified three themes: (i) the role of identity and self-categorizations in shaping sport performance, (ii) adjusting to identity loss (with subthemes indicating that this experience varied depending on the extent to which a person had multiple or exclusive identities), and (iii) attempts to remoor identity in the transition (with subthemes of searching for a new identity and actively repurposing identity). We interpret these themes through the lens of the Social Identity Model of Identity Change and show that this provides a framework for extending our understanding the complexities of identity change associated with retirement from elite sport.

RESUMO

Elite athletes often make large personal sacrifices to pursue excellence, but there is insufficient support for them when they leave elite sport. Identity loss is central to athletes' transition trajectories and hence the management of identity change is a crucial area for support. The More Than Sport (MTS) program is a novel digital intervention that aims to provide this support-helping athletes manage identity change in the process of leaving elite sport. The present research aims to study elite athletes' experiences with the MTS program and their perceptions of its usefulness in managing the transition away from elite sport. We undertook a qualitative study with athletes (N = 25) from three countries (the United Kingdom, Australia and Belgium) using reflexive thematic analysis to explore their experiences of the program and their feedback on program content. We identified three key themes and eight subthemes. The first key theme was Value of the Program, and this was underpinned by four sub-themes that centred on Program importance and novelty, how Positive and confronting experiences afford insight, the Value of developing shared understanding, and Realising the value of social groups. The second key theme was Engagement with Program Elements and here participants commented on Program content and Delivery format. The final key theme was Time and Place for Identity Management Programs which included the sub-themes of Optimal timing and Additional program beneficiaries. Overall, the results highlight the value of MTS specifically, and identity management efforts more broadly, to help elite athletes adjust successfully to life beyond sport.
