The present study tested the effects of self-efficacy, past performance, personal goal setting, and self-satisfaction on swimming performance. Participants (N = 42) performed four trials of a specific swimming task with 10-min intervals between each trial. During the third and fourth trials they performed trials after setting personal goals and completing self-efficacy and selfsatisfaction scales. Results showed significant improvement in level of performance in these two trials. Past performance, self-efficacy, self-satisfaction, and personal goal setting were predictors of performance at the third and the fourth trial. A LISREL VI path analysis indicated that past performance was the main determinant of future performance. Personal goal setting was affected by level of past performance, as well as by perceived self-efficacy and satisfaction. In a second stage of analysis, past performance was eliminated, and results supported the mediating role of personal goals between self-efficacy and performance.

Planned Behavior, Attitude Strength, Role Identity, and the Prediction of Exercise Behavior
Yannis Theodorakis
The aim of this study was to examine the attitude–exercise behavior relationship according to the theory of planned behavior. Two additional variables, multicomponent attitude strength and role identity, were constructed to expand the initial model. The participation of 395 females in physical fitness programs over a 2-month period served as a behavioral criterion. Attitudes toward behavior, perceived behavioral control, role identity, and attitude strength predicted intention to exercise. Also, exercise behavior was predicted from intention, perceived behavioral control, role identity, and attitude strength. Perceived behavioral control was a more accurate predictor of behavior than of intention. Results also showed that the planned behavior model was slightly more successful in predicting exercise behavior when attitude strength and role identity were added to the analysis. Findings are discussed in terms of theoretical and practical implications and in terms of the role of intention, perceived behavioral control, role identity, and attitude strength variables for understanding attitude–behavior relationships.
Enhancing Performance and Skill Acquisition in Novice Basketball Players with Instructional Self-Talk
Stefanos Perkos, Yannis Theodorakis, and Stiliani Chroni
This study examined the effectiveness of instructional self-talk on acquiring and performing three basketball skills (dribbling, passing, and shooting). Sixty-two young, novice players were organized into two groups. The experimental group accompanied the practice of three specific drills with self-talk. The control group performed the same drills traditionally. Six assessment sessions were completed. Repeated measures MANOVAs showed that experimental group participants performed better than their control group counterparts when dribbling and passing. Experimental group participants and their coaches reported using self-talk more when passing and dribbling and less when shooting. In addition, experimental group participants achieved significantly better dribbling and passing scores (p < .05) between assessment sessions. These results support instructional self-talk as an effective tool for skill acquisition and performance enhancement of skills low in complexity.
The Effects of Self-Talk on Dominant and Nondominant Arm Performance on a Handball Task in Primary Physical Education Students
Nikos Zourbanos, Antonis Hatzigeorgiadis, Dimitris Bardas, and Yannis Theodorakis
The present study examined the effects of instructional and motivational self-talk on handball performance using a novel task (nondominant arm) and a learned task (dominant arm) in primary school students. Participants were randomly assigned into two experimental groups (instructional and motivational) and one control group. The results revealed that for both tasks instructional and motivational self-talk groups improved their performance significantly in comparison with the control group and that for the nondominant arm instructional self-talk had a larger effect compared with motivational self-talk. The results suggest that instructional self-talk in the form of external focused cues may be more beneficial in the early stages of learning.
Investigating the Functions of Self-Talk: The Effects of Motivational Self-Talk on Self-Efficacy and Performance in Young Tennis Players
Antonis Hatzigeorgiadis, Nikos Zourbanos, Christos Goltsios, and Yannis Theodorakis
The purpose of the current study was to examine the effects of motivational self-talk on self-efficacy and performance. Participants were 46 young tennis players (mean age 13.26, SD 1.96 years). The experiment was completed in five sessions. In the first session, participants performed a forehand drive task. Subsequently, they were divided into an experimental and a control group. Both groups followed the same training protocol for three sessions, with the experimental group practicing self-talk. In the final session, participants repeated the forehand drive task, with participants in the experimental group using motivational self-talk. Mixed model ANOVAs revealed significant group by time interactions for self-efficacy (p < .05) and performance (p < .01). Follow-up comparisons showed that self-efficacy and performance of the experimental group increased significantly (p < .01), whereas self-efficacy and performance of the control group had no significant changes. Furthermore, correlation analysis showed that increases in self-efficacy were positively related to increases in performance (p < .05). The results of the study suggest that increases in self-efficacy may be a viable mechanism explaining the facilitating effects of self-talk on performance.
The Effects of Motivational versus Instructional Self-Talk on Improving Motor Performance
Yannis Theodorakis, Robert Weinberg, Petros Natsis, Irini Douma, and Panagiotis Kazakas
This study examined the effectiveness of different self-talk strategies on increasing performance in different motor tasks. Specifically, four laboratory experiments were conducted to examine the effect of motivational versus instructional self-talk strategies on four different tasks. Included in the experiments were a soccer accuracy lest, a badminton service test, a sit up test, and a knee extension task on an isokinetic dynamometer. Results of the first two experiments indicated that only the participants of the instructional group improved their performance significantly more than the motivational and control groups. Results of the third experiment indicated no significant differences between the three groups, although all groups showed improvements across trials. Results of the fourth experiment showed a significant improvement for both the motivational and instructional groups compared to the control group. It appears that when the task requires fine motor movements, an instructional self-talk strategy is more effective, whereas when the task requires predominantly strength and endurance, both motivational and instructional strategies are effective.
Automatic Self-Talk Questionnaire for Sports (ASTQS): Development and Preliminary Validation of a Measure Identifying the Structure of Athletes’ Self-Talk
Nikos Zourbanos, Antonis Hatzigeorgiadis, Stiliani Chroni, Yannis Theodorakis, and Athanasios Papaioannou
The aim of the present investigation was to develop an instrument assessing the content and the structure of athletes’ self-talk. The study was conducted in three stages. In the first stage, a large pool of items was generated and content analysis was used to organize the items into categories. Furthermore, item-content relevance analysis was conducted to help identifying the most appropriate items. In Stage 2, the factor structure of the instrument was examined by a series of exploratory factor analyses (Sample A: N = 507), whereas in Stage 3 the results of the exploratory factor analysis were retested through confirmatory factor analyses (Sample B: N = 766) and at the same time concurrent validity were assessed. The analyses revealed eight factors, four positive (psych up, confidence, anxiety control and instruction), three negative (worry, disengagement and somatic fatigue) and one neutral (irrelevant thoughts). The findings of the study provide evidence regarding the multidimensionality of self-talk, suggesting that ASTQS seems a psychometrically sound instrument that could help us developing cognitive-behavioral theories and interventions to examine and modify athletes’ self-talk.
