This study examined the appropriateness of self-report (predicted) data obtained from high-level golfers in tournament play. Twenty-one high-level golfers (mean ± s, handicap = +2.8 ± 1.8) completed one round of 18 holes. For approach-shots to the green on par 4 and 5 holes, three measurements were predicted by each player: a) Distance to Hole, b) Approach Shot Distance and c) Ball to Hole Distance, for on and around the green. A fourth variable, Percent Error Index (PEI) was also determined. Actual distances were measured using a combination of a laser rangefinder and tape measure. A series of accuracy, precision and agreement statistics were calculated. Despite between-distance differences being evident for some measures of precision, both low error and good between-method agreement was found for the four variables examined. Results from this study suggest that high-level golfers can utilise self-report data relating to approach-iron shots in golf.
