ABSTRACT: This study describes the adaptation of the State-Trait Anxiety Inventory for Children (STAIC; Spielberger, Edwards, Lushene, Montuori, & Platzek, 1973) to the Greek population. It was hypothesized that the STAIC would be able to measure children's state-trait anxiety levels. In the initial phase, a sample of 100 children, aged 9-12 years, was used in order to shape the final form of the inventory. In the final phase, two different samples (N=875), aged 9-12 years, were used to test the validity and reliability of the inventory, using exploratory (Sample A; n=425) and confirmatory (Sample B; n=450) factor analyses. The results indicated that both scales possessed an acceptable internal consistency and reliability. The factor analysis in the total of the items indicated three factors, that is "absence of state anxiety," "presence of state anxiety," and "trait anxiety." Also, confirmatory factor analysis (AMOS; Arbuckle, 1997) verified three factors. It is therefore concluded that the scales have a multifactorial structure and can be used among the Greek population to examine children's state and trait anxiety levels.

ABSTRACT: The present study describes the development and validation of an instrument designed to examine athletes' selective attention returning to competition following a musculoskeletal injury--the attention questionnaire of rehabilitated athletes returning to competition (AQ-RARC). Using a sample of 186 rehabilitated athletes, exploratory factor analysis revealed a 10-item model that examines functional attention and distraction attention. Confirmatory factor analysis further supported the factorial validity of the AQ-RARC with another sample of 184 rehabilitated athletes. The two subscales have good internal consistency and test-retest reliability. The concurrent and discriminant validity of the new instrument were confirmed by examining correlations between the AQ-RARC with other constructs. It is concluded that the AQ-RARC is a valid and reliable instrument that can be used for clinical and research purposes.

ABSTRACT: Re-injury worry is an important construct in competitive sport that may influence performance and increase the risk of re-injury. However, there are currently no available instruments to measure the causes of re-injury worry. The purpose of this study was to develop the Causes of Re-Injury Worry Questionnaire (CR-IWQ). The study was conducted in three independent research phases to investigate the following: (a) the content relevance, (b) the factor structure and the factorial validity, (c) the concurrent validity, (d) the discriminant validity, and (e) the test-retest reliability (intraclass correlation coefficients; ICC), and the internal consistency of the instrument. Exploratory factor analysis (EFA) was chosen to examine the factor structure of the CR-IWQ. Confirmatory factor analysis (CFA) was used to examine further the factorial validity of the instrument. A number of valid constructs were used to assess the concurrent and discriminant validity of the CR-IWQ. The reliability of the new instrument was examined using Pearson r (ICC) and Cronbach α. Three hundred and seventy athletes with an acute musculoskeletal sport injury in the last year participated in the study. EFA revealed a 12-item model, representing two factors ("Re-injury worry due to rehabilitation" and "Re-injury worry due to opponent's ability"). CFA supported the two-factor model of the CR-IWQ. The concurrent and discriminant validity of the CR-IWQ was confirmed by examining correlations between the CR-IWQ with other constructs. The ICCs and the Cronbach α indices of the CR-IWQ were acceptable. We have demonstrated that the CR-IWQ is a good psychometric instrument that can be used for clinical and research purposes.

ABSTRACT: This study employed Nicholls' social-cognitive approach to achievement motivation along with beliefs about the causes of success. The aims of the study were (a) to test the factor structure of the Greek adaptation of the Perception of Success Questionnaire and the Beliefs about the Causes of Sport Success Questionnaire in a sample of Greek track and field athletes, (b) to explore goal orientation and beliefs about the causes of success in the same sample of track and field athletes, and (c) to interpret both factor structures together, according to the respective theoretical frameworks of achievement motivation. The results verified the task and ego goal orientation dimensions for the Perception of Success Questionnaire. The proposed dimensions for the Beliefs about the Causes of Sport Success Questionnaire were also supported. Two dimensions were found when the two sets of factors were conjointly described, named "winning by all means" and "working hard," which might act as an alternative framework when dealing with achievement issues in sports.

ABSTRACT: The purpose of the present study was to examine the effectiveness of imagery on muscular endurance, dynamic balance, and functional stability in athletes who sustained a grade II ankle sprain. The sample consisted of 20 active athletes (aged from 18 to 30 years) with a grade II ankle sprain, as confirmed by ultrasound testing. The participants were randomly divided into two groups of 10 participants each; one experimental and one control group. The experimental group received 12 individual sessions of imagery rehearsal in addition to a normal course of physical therapy, while the control group followed only the physical therapy treatment. Results revealed significant differences only in the variable of muscular endurance. This study partly supports the contribution of imagery to the functional rehabilitation of grade II ankle sprain. Further research should be conducted to examine the effect of imagery on the functional rehabilitation of sport injuries using other tests of functional rehabilitation along with larger sample sizes.

ABSTRACT: The purpose of the present study was to examine the temporally patterned changes in intensity and direction of competitive state anxiety prior to and during competition as well as correlations among intensity and direction on the Competitive State Anxiety Inventory-2D subscale scores. 99 athletes completed the inventory one day before and an hour before the competition, based on how they felt during that time, and 30 min. after the competition with reference to how they felt during the competition. Analysis indicated different temporal patterning in subscale scores prior to competition. Correlations were medium (.40) for Intensity and Direction dimensions. Significant differences were noted between scores of those classified as Facilitators and Debilitators on the Intensity dimension. The results support the multidimensional nature of competitive anxiety. Moreover, additional information lies in directional interpretation of competitive anxiety and self-confidence.

ABSTRACT: The purposes of the current study were to examine (a) the differences in Flow State Scale (FSS) subscales between the 4 experiential states of the orthogonal model (apathy, anxiety, relaxation, and flow), (b) the relationship between challenge, skills, and flow experience; and (c) the relationship between flow experience and athletes' performance. Two hundred twenty athletes volunteered to participate in this study. Challenge of the game and skills of the athlete were measured before and after competition. Thirty minutes after the competition, the FSS was used to measure flow experience. In addition, subjective and objective measures of athletes' performance were assessed. Athletes in the flow and relaxation states revealed the most optimal states, whereas the athletes in the apathy state showed the least optimal state. There were positive associations between athletes' flow experience and their performance measures, indicating that positive emotional states are related to elevated levels of performance. On the other hand, there were low or no correlations between athletes' performance and reported challenge of the game, whereas skills of the athlete were moderately correlated with flow. Multipleregression analysis demonstrated significant prediction of athletes' performance based on flow experience during competition. Future research should examine the relationship between flow, athletes' performance, and additional dispositional and state variables.
