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.

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.

The aim of this study was to examine attitudes and intentions of physical education students toward teaching individuals with disabilities. The planned behavior model and two exogenous variables (attitude strength and role identity) were used to examine antecedents of students’ intentions for teaching individuals with disabilities in the future. The sample consisted of 99 university students taking adapted physical education courses. Structural equation modeling analysis showed that the role identity and attitude strength variables mediated the effects of subjective norms and attitudes toward behavior on intention. Also, perceived behavioral control was not a direct determinant of intention but affected the attitude strength variable. Findings are discussed in terms of theoretical as well as practical implications for understanding attitude-behavior relationships in physical education for special populations. It seems that professionals’ intentions to work with individuals with disabilities are formed as part of their role identity in the society and are affected by professionals’ attitude confidence toward teaching individuals with disabilities.

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 aim of this study was to examine the effectiveness of goal setting on performance and on a number of psychological variables such as self-efficacy, pretesting anxiety, and self-satisfaction during an injury rehabilitation program. An experimental group (n = 20) and a control group (n = 17) of injured physical education students were studied. Both groups underwent a 4-week quadriceps strengthening program on an isokinetic dynamometer, with the experimental group setting specific personal goals in each training session. The experimental group improved in performance significantly more than the control group. Although both groups exhibited an increase in self-efficacy and a decrease in pretesting anxiety, only the experimental group had an increase in self-satisfaction with performance. Results confirm that incorporating goal setting in the rehabilitation process enhances rehabilitation results.

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.

The aim of the present research was to investigate the relationship between coaching behavior and athletes’ inherent self-talk (ST). Three studies were conducted. The first study tested the construct validity of the Coaching Behavior Questionnaire (CBQ) in the Greek language, and provided support for its original factor structure. The second study examined the relationships between coaching behavior and athletes’ ST in field, with two different samples. The results showed that supportive coaching behavior was positively related to positive ST (in one sample) and negatively related to negative ST (in both samples), whereas negative coaching behavior was negatively related to positive ST (in one sample) and positively related to negative ST (in both samples). Finally, the third study examined the relationships experimentally, to produce evidence regarding the direction of causality. The results showed that variations in coaching behavior affected participants’ ST. Overall, the results of the present investigation provided considerable evidence regarding the links between coaching behavior and athletes’ ST and suggested that coaches may have an impact on athletes’ thoughts.

This study examined the effect of goal setting on injury rehabilitation, specifically, differences in personal goal setting, self-efficacy, self-satisfaction, and performance between injured and noninjured subjects. Two experimental groups (32 women with knee injuries and 29 noninjured women) and one control group (n = 30) were used. Subjects performed four trials of a knee extension task on an isokinetic dynamometer. Prior to the third and fourth trials, subjects in the experimental groups set personal goals and completed self-efficacy and self-satisfaction scales. There were significant performance improvements for the two experimental groups; correlation coefficients between self-efficacy, self-satisfaction, goal setting, and performance were significant at the .001 level Personal goal setting was affected by level of ability and in turn had a direct effect on performance. Self-efficacy and self-satisfaction were affected by ability or performance but had no significant effect on personal goals or performance. The findings indicate that personal goal setting might be an important determinant for performance improvement in injury rehabilitation programs.

Motivational climate is inherently a group-level construct so that longitudinal, multilevel designs are needed to evaluate its effects on subsequent outcomes. Based on a large sample of physical education classes (2,786 students, 200 classes, 67 teachers), we evaluated the effects of classroom motivational climate (task-involving and ego-involving) and individual goal orientations (task and ego) on individual students’ outcomes (intrinsic motivation, attitudes, physical self-concept, and exercise intentions) collected early (T1) and late (T2) in the school year. Using a multilevel approach, we found significant class-average differences in motivational climate at T1 that had positive effects on T2 outcomes after controlling T1 outcomes. Although there was no support for a “compatibility hypothesis” (e.g., that task oriented students were more benefited by task-involving motivation climates), the stability of goal orientations was undermined by incompatible climates.

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.
