PURPOSE This study both validated the Characteristics of Resilience in Sports Teams Inventory (CREST) scale for use in Korean sports and analyzed the impact of team resilience on teamwork and performance. METHODS The study surveyed 462 elite football players by using the CREST scale to measure team resilience in Korean sports. Data were analyzed using descriptive statistics, exploratory factor analysis (EFA), reliability analysis, correlation analysis, multiple regression analysis, and confirmatory factor analysis (CFA). RESULTS First, results confirmed that the CREST scale’s two main factors—resilient characteristics and vulnerabilities under pressure—can be meaningfully applied in the Korean context. Second, resilient characteristics showed positive correlation with life skills, whereas vulnerabilities under pressure showed negative correlation. Third, resilient characteristics positively predicted life skills, whereas vulnerabilities under pressure negatively affected life skills. CONCLUSIONS The CREST scale was found reliable and valid in the Korean sports context, demonstrating that team resilience significantly impacts life skills. Thus, the study contributes to evaluation of resilience in Korean sports teams and provides strategicinsights to improve team performance.
PURPOSE This study aimed to examine the mediating effect of psychological needs in the relationship between multiple coaching styles and teamwork among college football players. METHODS This cross-sectional study involved 526 elite football players. Descriptive statistics, reliability analysis, confirmatory factor analysis, correlation analysis, path analysis, and macroprocess were performed using statistical software to test the mediation effects of the data collected. RESULTS The findings suggested that autonomy-supportive and structure coaching styles positively correlated with and impacted psychological needs satisfaction and teamwork. Conversely, control and chaos coaching styles negatively correlated with and impacted psychological needs satisfaction and teamwork. In addition, autonomysupportive and structure coaching styles negatively correlated with and impacted psychological need frustration, while control and chaos styles positively correlated with and impacted psychological needs frustration. Furthermore, psychological needs satisfaction and frustration were found to partially mediate the relationships between autonomy support and teamwork, structure and teamwork, control styles and teamwork, and chaos styles and teamwork. CONCLUSIONS Autonomysupportive and structure coaching styles positively influenced teamwork by satisfying psychological needs. In contrast, control and chaos coaching styles negatively impacted teamwork by contributing to psychological needs frustration.
