The purposes of this study were to investigate the effects of goal-setting and imagery programs, as well as a combined goal-setting and imagery training program, on the free-throw performance among female collegiate basketball players over the course of an entire season. A multiple-baseline, single-subject A-B-A design was employed in which participants were randomly assigned to one of three interventions: (a) goal-setting (n = 4), (b) imagery (n = 4), or (c) goal-setting and imagery (n = 4). Free-throw data were collected during practice sessions. Data were examined by way of changes in mean, level, trend, latency, and variability between baseline and intervention, and then between intervention and a second baseline phase. Three participants in the goal-setting program, and one participant in the goal-setting and imagery program, increased their mean free-throw performance from baseline to intervention. However, three participants in the imagery program decreased their mean free-throw performance from baseline to intervention. Goal discrepancy scores also were investigated. A positive correlation was found between participants’ free-throw performance and personal goals.
