Psychological skills training and perfectionism: a single-subject multiple baseline study

Psychological skills training (PST) is a common and effective form of support provided by sport psychologists. Nevertheless, its use in helping support athletes with perfectionism and some of the problematic issues they can face is unknown. The purpose of the present study was to assess the effectiveness of PST in reducing perfectionistic cognitions and improving emotion experiences in athletes. Using a single-subject multiple baseline research design, we recruited five national level basketball players (M = 21.8 years) based on their concerns over mistakes (a key dimension of perfectionistic concerns). All participants received eight, one-to-one PST sessions over a four-week period. Participants completed self-report measures of perfectionistic cognitions, cognitive appraisals, pre-competition emotions, and performance satisfaction on a weekly basis, before, during, and after the intervention, as well as three-months later. Results suggested that PST improved at least some of the cognitive appraisals, pre-competition emotions and performance satisfaction in most participants. Minimal changes were observed for perfectionistic cognitions. The findings support the general use of PST but other interventions may be required to reduce perfectionistic cognitions
