This study reports the effects of a hypnosis intervention on a professional soccer player who reported low self-efficacy and a negative mood state relative to his soccer performance. Pre- and postintervention data were collected via a Soccer Self-Efficacy Questionnaire (SSEQ) that consisted of 10 items relating to good soccer performance, the Trait Sport Confidence Inventory (TSCI), the Positive and Negative Affect Schedule (PANAS), and a Soccer Performance Measure (SPM). An intervention program consisting of eight hypnosis sessions was conducted. These sessions comprised the presentation of ego-strengthening suggestions. Both visual and statistical analysis revealed substantial increases in trait sport confidence, self-efficacy, positive affect, and soccer performance, as well as a substantial decrease in negative affect over the course of the intervention. The findings of this case study suggest that hypnosis can be used to enhance self-efficacy, affect, and sport performance. A number of practical issues are presented surrounding the use of hypnosis in the context of English soccer and with athletes in general.

High levels of self-efficacy have been documented to be associated with optimal levels of sport performance. One technique, which has the potential to foster increased self-efficacy, is hypnosis. Hypnosis is based upon the power of suggestion and, while often shrouded in myth and controversy, has been used in a number of domains including medicine, dentistry, and psychotherapy. In contrast, sport psychology is one domain where the use of hypnosis has yet to be fully explored. The aim of this review is to add to the extant literature and delineate how hypnosis potentially can enhance self-efficacy. By drawing on neodissociation and nonstate theories of hypnosis, a combined theoretical basis is established to explain how hypnosis may be used to influence sport performers’ sources of self-efficacy information. Furthermore, the review examines these theoretical postulations by presenting contemporary research evidence exploring the effects of hypnosis on sport performers’ self-efficacy. The review concludes with future research directions and suggestions for sport psychologists considering the use of hypnosis within their practice.
