The purpose of this study was to investigate the roles of psychological characteristics (e.g., self-efficacy and mental toughnes) and psychological skills (e.g., imagery, goal-setting, and self-talk) inpredictingThai golfers’ status between professionals and amateurs. By non-propabilistic random sampling, one hundred and eighty-four Thai golfers completed the measures of mental toughness, test of performance strategies, and golf self-efficacy. The results showed that five predictors significantly predicted Thai professional and amateur golfers after controlling for their current scores. Moreover, the odd ratios have suggested that the more the golfer used imagery in competition, the more likely he or she played in an amature league.Two multiple regression models showed that self-efficacy significantly predicted Thai professional golfers’ scoreswhile self-talk significantly predicted amateur golfers’ scores.
