Syftet med studien var att undersöka a) om behovstillfredsställelse medierar relationen mellan ett autonomistödjande ledarskap och idrottslig utbrändhet hos unga elitsatsande lagidrottare b) om behovsfrustration medierar relationen mellan ett kontrollerande ledarskap och idrottslig utbrändhet hos unga elitsatsande lagidrottare. Studien har en kvantitativ longitudinell design och insamling av data skedde via digitala enkäter. Antalet deltagare som deltog vid båda mättillfällena inkluderades i studien, vilket var 71 idrottare. Samtliga deltagare utövade lagidrott och studerade på Nationellt godkända idrottsutbildningar. Baserat på tidigare forskning och Self-Determination Theory ställdes två hypoteser 1) behovstillfredsställelse medierar relationen mellan ett autonomistödjande ledarskap och idrottslig utbrändhet och 2) behovsfrustration medierar relationen mellan ett kontrollerande ledarskap och idrottslig utbrändhet. Hypoteserna bekräftades med hjälp av två genomförda medieringsanalyser. Resultatet stödjer tidigare forskning och teori, samt belyser vikten av ett autonomistödjande ledarskap för att genom behovstillfredsställelse kunna bidra till lägre nivåer av idrottslig utbrändhet. / The aim of the study was to investigate a) if basic need satisfaction mediates the relationship between autonomy-supportive leadership and athlete burnout in young elite team athletes, and b) if basic need thwarting mediates the relationship between controlling leadership and athlete burnout in young elite team athletes. The study used a quantitative longitudinal design and data collection took place via digital surveys. The number of participants who took part in both measurement occasions was included in the study, which was 71 athletes. All participants played team sports and studied at Nationally approved sport education. Based on previous research and Self-Determination Theory, two hypotheses were formulated 1) need satisfaction mediates the relationship between an autonomy-supportive leadership and athlete burnout and 2) need thwarting mediates the relationship between a controlling leadership and athlete burnout. The hypotheses were confirmed with the help of two conducted mediation analysis. The result supports previous research and theory and highlights the importance of an autonomy-supportive leadership in order to contribute to lower levels of athlete burnout through need satisfaction.

Includes bibliographical references: leaves 255-277 / Self-leadership has emerged as a leadership style that can be utilised to achieve successful performance for the individual and the organisation, prompting the question: What can be done to facilitate self-leadership within nurse educators in nursing education institutions? The purpose of this exploratory, descriptive sequential mixed-methods study was to understand the self-leadership within nurse educators in order to develop guidelines that could facilitate their self-leadership. The integrative literature review, qualitative and quantitative data were integrated and used to develop and validate guidelines that could facilitate self-leadership in nurse educators. Phase 1 (subphase 1) consisted of an integrative literature review that explored and described the concept of self-leadership in nurse educators. In Phase 1 (subphase 2), semi-structured focus group interviews were conducted with purposively selected nurse educators from three sampling units, namely a private nursing school, nursing college and university-based nursing departments in two of the nine provinces in South Africa to explore the nurse educators’ perception of their self-leadership, and how self-leadership could be facilitated in a nursing education institution. Phase 2 of the study entailed developing a structured questionnaire based on the findings of Phase 1. In Phase 2, quantitative data were collected from nurse educators appointed at the remaining nursing education institutions in the two provinces which were not selected for the qualitative phase of the study. This phase was aimed at determining and describing the nurse educators’ (n=265) perceptions on their self-leadership practices in a nursing education institution, using a selfadministered questionnaire. For the integrative literature review, the method of data analysis as outlined by Miles and Huberman was used (Whittemore & Knafl 2005:550– 552). The qualitative data were analysed according to Tesch’s protocol of data analysis. The themes that emerged were perceptions of self-leadership in nurse educators; engagement in self-leadership activities; motivational factors in self-leadership; and facilitation of self-leadership in nurse educators. The quantitative data were analysed using descriptive statistical methods (SPSS version 25). The participants gave their perceptions on 11 composite constructs. Nurse educators agreed the most on natural reward, intrinsic motivation, role modelling and shared leadership but agreed less with management support and positive self-talk. To establish rigour, the researcher utilised diverse empirical and theoretical sources as data sources, and applied strategies to ensure trustworthiness and performed validity and reliability tests. The findings of both Phase 1 and 2 were integrated to develop and validate guidelines to facilitate the self-leadership in nurse educators. Twelve guidelines were developed and were validated by field experts. The guidelines propose recommendations for nurse educators and the management of the nursing education institution, as well as other associated stakeholders such as SANC and government. / Health Studies / D.
