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.

The use of rational emotive behavior therapy (REBT) in sport psychology has received scant research attention. Therefore, little is known about how REBT can be adopted by sport psychology practitioners. This paper principally outlines how practitioners can use REBT on a one-to-one basis to reduce irrational beliefs in athletes. Guidance is offered on the introduction of REBT to applied contexts, the REBT process through which an athlete is guided, and offers an assessment of the effectiveness of REBT with athletes. It is hoped that this paper will encourage other practitioners to adopt REBT in their work and to report their experiences.

The present paper reports the impact of hypnosis, technique refinement, and selfmodeling on the self-efficacy levels of a cricket leg-spin bowler. A single-subject (A-B) design was employed with the collection of 8 baseline data points and 16 post-intervention data points that included 8 data points collected 7 months after the intervention. The intervention comprised three aspects. Aspect one focused on using hypnosis and self-hypnosis to increase self-efficacy. Aspect two was based around refining the bowler’s technique, focusing on the run-up, head position, and follow-through. Aspect three focused on self-modeling through the use of an edited videotape. The results revealed a significant difference between pre and post-intervention self-efficacy levels. This positive change was maintained in the long-term follow-up data. Also an increase in bowling performance was noted across the intervention. A number of consultancy issues are presented surrounding the use of hypnosis as part of a multimodal intervention.

This study examined the effectiveness of a longitudinal 5C coaching intervention (Harwood, 2008), focused on promoting behavioral responses associated with commitment, communication, concentration, control, and confidence in youth soccer players. Five players, their parents and a youth academy soccer coach participated in a single-case multiple-baseline across individuals design with multiple treatments. Following baseline, the coach received sequential education in the principles of each C subsequent to integrating relevant strategies in their coaching sessions. During the five intervention phases, players completed assessments of their behavior in training associated with each C, triangulated with observationbased assessments by the coach and the players’ parents. Results indicated psychosocial improvements with cumulative increases in positive psychosocial responses across the intervention for selected players. Changes in player behavior were also corroborated by parent and coach data in conjunction with postintervention social validation. Findings are discussed with respect to the processes engaged in the intervention, and the implications for practitioners and applied researchers.

Rational emotive behavior therapy (REBT; Ellis, 1957) is a psychotherapeutic approach receiving increasing interest within sport. REBT is focused on identifying, disputing, and replacing irrational beliefs (IBs) with rational beliefs (RBs) to promote emotional well-being and goal achievement. This study provides a detailed case outlining the application and effect of seven one-to-one REBT sessions with an elite level archer who was experiencing performance-related anxiety, before and during competition. The case also offers an insight into common misconceptions, challenges, and guidance for those who may consider applying REBT within their practice. Data revealed meaningful short and long-term (6-months) reductions in IBs and improvements in RBs, self-efficacy, perception of control and archery performance. The case supports the effective application of REBT as an intervention with athletic performers, promoting lasting changes in an athlete’s ability to manage their cognitions, emotions and behaviors in the pursuit of performance excellence.

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.

Research examining the effects of rational emotive behavior therapy (REBT) on athletic performance is emerging. There is, however, a paucity of research exploring psychological interventions in specialized sport populations. The present study investigated the effects of a single REBT workshop, including intellectual and practical insight into the ABC(DE) framework, on psychological, physiological, and performance markers in an elite blind soccer team. From use of a within-participant pretest–posttest crossover design in an ecologically valid setting, data indicated small and immediate reductions in irrational beliefs, perceived helpfulness of preperformance anxiety, and physiological markers (i.e., systolic blood pressure) prior to a penalty-kick simulation. However, no substantial changes were shown in penalty-kick performance. In sum, although the findings elucidate some benefits of a single REBT workshop, the educational insight into the ABC(DE) framework was deemed insufficient for meaningful changes in outcome measures. Practical implications and recommendations for future researchers are discussed.

The present study examined the effects of personal-disclosure mutual-sharing (PDMS) on a diverse set of group factors in a previously unexplored context. During a single bout of PDMS, 14 soccer-academy athletes voluntarily disclosed unknown personal stories to fellow teammates. Social identity, friendships identity content, results identity content, and collective efficacy were measured at baseline, post-PDMS, follow-up, and maintenance phases. In addition, team performance over the competitive season was assessed via goal difference and goal discrepancy. Data indicated that a short-term significant increase in friendships identity content and a sustained improvement in team performance occurred after the PDMS session, and social identity, results identity content, and collective efficacy remained elevated across all intervention phases. Data suggest that PDMS fosters immediate increases in aspects of team functioning that may exert a positive influence upon team performance. Future research would benefit from ascertaining the exact mechanisms in which PDMS encourages changes in team outcomes observed within the current study.

In a one group pretest-posttest design, 15 elite academy cricketers were exposed to two personal-disclosure mutual-sharing (PDMS) sessions during a preseason tour. Within PDMS1, athletes disclosed (via prepared speeches) relationship-oriented information and within PDMS2, mastery oriented information. Social identity, social identity content, and collective efficacy were measured at baseline (1 week before the tour), post-PDMS1, midpoint, and post-PDMS2, while social validation was also obtained after each intervention session. Quantitative data revealed significant increases in social identity and friendships identity content at post-PDMS1, and results identity content and collective efficacy at post-PDMS2. Qualitative social validation data highlighted the thoughts and feelings of the athletes before their speeches and supported the effectiveness of the PDMS sessions. In sum, the data suggest practitioners can develop team outcomes (e.g., a focus on results) through developing specific aspects of teams’ identities. Study limitations, practitioner guidelines, and areas for future research are discussed.

This study assessed whether cardiovascular (CV) reactivity patterns indexing challenge and threat states predicted batting performance in elite male county (N = 12) and national (N = 30) academy cricketers. Participants completed a batting test under pressure, before which CV reactivity was recorded in response to ego-threatening audio instructions. Self-reported self-efficacy, control, achievement goals, and emotions were also assessed. Challenge CV reactivity predicted superior performance in the Batting Test, compared with threat CV reactivity. The relationships between self-report measures and CV reactivity, and self-report measures and performance were inconsistent. A small subsample of participants who exhibited threat CV reactivity, but performed well, reported greater self-efficacy than participants who exhibited threat CV reactivity, but performed poorly. Also a small subsample of participants who exhibited challenge reactivity, but performed poorly, had higher avoidance goals than participants with challenge reactivity who performed well. The mechanisms for the observed relationship between CV reactivity and performance are discussed alongside implications for future research and applied practice.
