The purpose of this study was to examine elite youth athletes’ knowledge, perceptions, and understanding of sport psychology, psychological characteristics, and psychological skills. To address this purpose an interpretive description methodology was employed. Data were collected through five focus groups with 34 elite youth swimmers, triathletes, and athletes (aged 13–20 years). Following each focus group, the recordings were transcribed verbatim and analyzed using thematic analysis. The first theme labeled perceptions, knowledge, and experiences of sport psychology encompassed athletes’ current and future perceptions of sport psychology as well as the factors impacting on athletes’ perceptions of sport psychology. The second theme was psychological characteristics for success in elite sport, which included athletes’ perceptions of the characteristics held by other elite athletes as well as the development of their own characteristics. The final theme accounted for the psychological skills deemed necessary for success in elite sport. Overall, the findings provide an insight into youth athletes’ varying perceptions of sport psychology, as well as their limited knowledge and understanding of key psychological considerations for sport. Lay Summary: Focus groups were used to explore the perception and understanding of sport psychology of elite youth athletes involved in swimming, athletics, and triathlon. Overall perceptions of sport psychology were varied, with multiple factors impacting upon them including the use and understanding of sport psychology, as well as coaches’ perceptions. IMPLICATIONS FOR PRACTICE Athletes should be provided with the opportunity to be educated on the benefits of sport psychology from a young age, so that as they progress they are aware of what it is, how it can be of use, and when they might choose to use it. Athletes would also benefit from being taught about the variety of characteristics that elite athletes possess and the available psychological skills that are commonly used to enhance performance. In addition to educating athletes, it could be beneficial for national governing bodies to also educate coaches around the topic of sport psychology given their influence on athletes.
