Qualitative research has consistently demonstrated that sport resilience encapsulates a mixed package of <i>resilience qualities</i> (reflecting positive traits and characteristics) and <i>resilience support</i> (reflecting perceived support and related resources). Ironically, sport resilience research adopting quantitative methods has been assessing resilience as a unidimensional construct, with little attention to the multi-facet nature of resilience and its effects on performance. In the present research, we tested a novel proposition that resilience qualities predict reduced pre-competition cognitive anxiety and contribute to performance more than resilience support. <b>Methods</b> <b>&</b> <b>Results:</b> Across two samples of competitive table tennis players (Study 1: <i>N</i> = 196 competing at province level; Study 2: <i>N</i> = 106 competing at national level), we consistently found resilience qualities, rather than resilience support, predicted lower levels of pre-competition cognitive anxiety and superior performance at a national championship. Results also suggest that pre-competition cognitive anxiety mediated the relationship between resilience qualities and performance. <b>Conclusion:</b> The findings provide the first evidence supporting the divergent effects of resilience qualities and resilience support in predicting pre- competition anxiety and championship performance and call for the consideration of such a distinction when designing and delivering resilience programs.</p>","PeriodicalId":54491,"journal":{"name":"Research Quarterly for Exercise and Sport","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10561402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
