Coaches frequently seek new methods to improve performance. The mental skills training of imagery combined with positive self-review has emerged as a possible device to improve athletic performance. This study was designed to examine the effectiveness of imagery and positive self-review on basketball game performance. Four male intercollegiate basketball players were chosen to participate in a single-subject, multiple baseline across subjects design. Baseline percentages of correct performance were compared to post-intervention percentages. Evidence indicated that the intervention was effective across all four participants. Results indicated a mean Win Score (Berri, Schmidt, & Brooks, 2006) increase of .74 across the four athletes. Social validation was also evaluated through exit questionnaires. All of the participants indicated that they enjoyed the intervention and felt that it improved their overall performance.
