Psychological factors affecting golfing performance have been widely researched within the sport psychology literature. Although there is a general consensus on these, the sport offers a unique environment whereby at the highest-level golfers compete with a caddie. Despite the proximity and potential influence on the golfer, the role and perspective of the caddie has been overlooked. This study therefore sought to ascertain caddies' perceptions of their role in facilitating a golfer's psychological performance. One semi-structured interview was conducted with seven male active caddies (M age = 35.57, SD = 9.78), working across six professional tours. Caddies reported a mean experience of 9.25 years (SD = 8.39) and 1.7 years with their current player (SD = 1.09). Transcripts were analyzed using thematic analysis. Three themes were identified: a) it's more than carrying a bag, b) caddying, it's a people thing, and c) confidence is a two-way street. The study provides an insight to the role of the caddie, the specific processes employed, and the factors which influence their ability to facilitate a golfer's psychological performance. It is intended that findings and implications for practice will enhance understanding for professionals and sport psychologists working within golf. In addition, educational tools are warranted to develop the knowledge and subsequent evidence-based practice of aspiring and currently active caddies.
