Adolescent athletes can use psychological skills immediately after being taught, but a dearth of empirical evidence exists regarding whether these skills are maintained over time. A 12-week curriculum (i.e., UNIFORM; Gilbert, 2011) was taught to a high school varsity soccer team with three data collection points: pretest, posttest, 4-week follow-up. Use of several skills was significantly greater posttest compared with pretest as measured by the Test of Performance Strategies (Thomas, Murphy, & Hardy, 1999). Follow-up results were also salient. Relaxation, imagery, and self-talk use in practice was significantly greater than pretest at follow-up; relaxation, imagery, goal setting, and self-talk in competition showed similar results. Descriptive statistics and qualitative data triangulate these results. The UNIFORM curriculum enabled the athletes to use the skills more consistently. This study makes a contribution by measuring the skills at follow-up and providing evidence of their continued use four weeks after the curriculum’s conclusion.
