We assessed the factor structure of a revised version of the Exercise Imagery Inventory (ELI; Giacobbi, Hausenblas, & Penfield, 2005), second-order interrelationships for cognitive and motivational forms of mental imagery, and associations with exercise behavior and barriers self-efficacy. A convenience sample of 358 (M age = 20.55 years, SD = 3.88) college students completed the EII-revised (EII-R), a measure of barriers self-efficacy and the Leisure-Time Exercise Questionnaire. The EII-R demonstrated reliability and factorial validity with good model fit statistics. We observed second-order relationships among scale scores and discriminant validity evidence that distinguished cognitive (e.g., exercise technique, exercise routines) and motivational (e.g., appearance/health, exercise self-efficacy, exercise feelings) factors. The second-order imagery factors were significantly and moderately associated with barriers self-efficacy and exercise behavior.  相似文献

The purpose of this study was to determine whether the ALT-PE system (Version 2) is valid as a process approach to estimate student achievement. Students (N = 60) were randomly selected from a data base that includes pretest and posttest scores for two volleyball skills and seven sessions of videotaped instruction. Videotapes were collected using two cameras with a split-screen generator so most instruction and practice could be seen. ALT-PE data were coded from the videotapes. In addition to normal ALT-PE coding conventions, coders recorded the skill that was the focus of instruction. Combinations of context and learner involvement categories were summed for each skill across the seven class sessions and to form other logical categories (e.g., total motor appropriate intervals). Achievement scores were calculated by posttest on pretest regression for each skill with the residual score used for subsequent analysis. Residual achievement scores were correlated with summed ALT-PE categories. The results indicate for the serve both total motor appropriate and practice-motor appropriate intervals were related to student achievement. For the pass, practice-motor appropriate intervals were related to achievement and the total motor appropriate-achievement correlation failed significance. These results demonstrate the validity of the ALT-PE system as a process measure of achievement can be partially substantiated.  相似文献

This study examined the validity and reliability of decisional balance scales for exercise (i.e., pros and cons) in a large longitudinal population-based randomized sample of Canadian adults ages 18 to 65 years (N = 703). Assessments were taken over 3 time points with 6-month intervals between testing. Content, factorial, concurrent, and construct validity along with internal consistency and test-retest reliability were established for the decisional balance scales. The developed measures have utility for researchers and practitioners who test and apply the exercise decisional balance constructs of the Transtheoretical Model.  相似文献

Self-determination theory (SDT; Deci & Ryan, 2000) proposes that intrinsic, relative to extrinsic, goal content is a critical predictor of the quality of an individual's behavior and psychological well-being. Through three studies, we developed and psychometrically tested a measure of intrinsic and extrinsic goal content in the exercise context: the Goal Content for Exercise Questionnaire (GCEQ). In adults, exploratory (N = 354; Study 1) and confirmatory factor analyses (N = 312; Study 2) supported a 20-item solution consisting of 5 lower order factors (i.e., social affiliation, health management, skill development, image and social recognition) that could be subsumed within a 2-factor higher order structure (i.e., intrinsic and extrinsic). Evidence for external validity, temporal stability, gender invariance, and internal consistency of the GCEQ was found. An independent sample (N = 475; Study 3) provided further support for the lower order structure of the GCEQ and some support for the higher order structure. The GCEQ was supported as a measure of exercise-based goal content, which may help understand how intrinsic and extrinsic goals can motivate exercise behavior.  相似文献

Despite the limitations of overgeneralizing cutoff values for confirmatory factor analysis (CFA; e.g., Marsh, Hau, & Wen, 2004), they are still often employed as golden rules for assessing factorial validity in sport and exercise psychology. The purpose of this study was to investigate the appropriateness of using the CFA approach with these cutoff values for typical multidimensional measures. Furthermore, we ought to examine how a model could be respecified to achieve acceptable fit and explored whether exploratory structural equation modeling (ESEM) provides a more appropriate assessment of model fit. Six multidimensional measures commonly used in sport and exercise psychology research were examined using CFA and ESEM. Despite demonstrating good validity in previous research, all eight failed to meet the cutoff values proposed by Hu and Bentler. ESEM improved model fit in all measures. In conclusion, we suggest that model misfit in this study demonstrates the problem with interpreting cutoff values rigidly. Furthermore, we recommend ESEM as a preferred approach to examining model fit in multidimensional measures.  相似文献

The purpose of this study was to provide a systematic review of studies on athletes' career transition out of sport from 1968 until the end of 2010. A total of 126 studies were evaluated and reported in three sections: sample characteristics, research designs and correlates of athletes' career transition adjustment. Samples ranged from 1 to 1617. Investigators examined a wide range of competitive levels, both genders and various sports. Researchers have used qualitative (44%), quantitative (44%), and mixed-model (12%) designs. Variables correlated to athletes' career transition adjustment were categorized into factors related to career transition (e.g., self-identity) and available resources during the career transition process (e.g., social support). The discussion focuses on the current status of the study area, limitations in its knowledge, suggested practical implications (e.g., providing proactive support) and future research directions (e.g., examining athletes' retirement decision-making process).  相似文献

ABSTRACT

The purpose of this study was (1) accurately estimate longitudinal relationships between decimal age (i.e., chronological and relative) and performance in Australian female 100 m (N = 765) and 200 m (N = 428) Breaststroke swimmers (10–18 years); and (2) determine whether corrective adjustment procedures could remove Relative Age Effects (RAEs) in an independent sample of age-matched 100 m (N = 2,491) and 200 m (N = 1,698) state/national level Breaststroke swimmers. In Part 1, growth curve modelling quantified longitudinal relationships between decimal age and swimming performance. In Part 2, relative age distributions (Quartile 1–4) for “All”, “Top 25%” and “10%” of swimming times were examined based on raw and correctively adjusted swim times for age-groups. Based on raw swim times, finding identified RAE effect sizes increased in magnitude (small-medium) with selection level (“All”-“Top 25%”) in 12–14 years age-groups for both events. However, when correctively adjusted swim performances were examined, RAEs were primarily absent across all age-groups and selection levels. Using longitudinal reference data, corrective adjustment procedures removed relative age advantages in female youth Breaststroke performance. Removing the influence of relative age-related differences is predicted to improve the accuracy of identifying genuinely skilled youth swimmers.  相似文献

This study was designed to develop a racquetball skills test battery for young adult beginners. Based on a review of literature and the content validity phase, 5 racquetball skills components with 8 test items were formulated: service placement (left and right), power drive (forehand and backhand), power shot placement (forehand and backhand), ceiling shot, and wall rally. Participants (N = 131) were 87 male and 44 female college students who were provided two 90-min sessions of practice and preparation 1 week before the testing. The test was conducted on 2 official size racquetball courts. Each test item had 20 trials (3 trials for wall rally), and each was administered twice within 1 week. A single round-robin tournament was conducted for male and female participants, respectively. Participants were simultaneously evaluated on their overall skill levels by a trained evaluator using a subjective 5-point rating scale. Data on subjective rating and tournament standing were used as criterion variables for examining the test validity. Intercorrelations revealed that all test items had validity coefficients equal to or greater than .50, except for 2 items, service placement to the left and the right, which were dropped from further analysis. Multiple regression analyses revealed that the remaining 6 skills test items were predictive of the 2 criterion variables, with the multiple correlations equal to .67 and .68 for males and .61 and .75 for females. Using factorial repeated measures analysis of variance, generalizability reliability was computed. The G coefficients for the items ranged from .61 to .84. The D studies revealed that testing over a minimum of 2 days would be the best test protocol for most racquetball skills test items. To achieve sufficient reliability (i.e., G coefficient >>.70), the minimum number of trials administered each day was suggested for each item.  相似文献

This study was designed to investigate the status of teachers' use of fitness tests in school-based physical education programs. Full-time physical education teachers (N = 325) in 10 states participated. A questionnaire was developed specifically for this study to collect data. Various methods were utilized to lend evidence for the reliability and validity of the items on the questionnaire. Means and standard deviations of continuous variables and Likert-type variables were computed. Frequencies of category variables were calculated and percentages of the frequencies were reported. The results were: (a) most of the teachers used fitness tests with the majority using nationally available fitness tests (among those who implemented the nationally available fitness tests, most utilized the norm-referenced test [i.e., President's Challenge, 1998] and not criterion-referenced tests [i.e., the Fitnessgram, or YMCA Youth Fitness Test Program]), (b) teachers in general implemented different approaches to prepare students for fitness testing and most teachers informed students verbally about the tests in advance, (c) helping students gain awards was the least important purpose for teachers to use fitness tests, and (d) fitness testing was not strongly associated with teachers' fitness/physical activity instruction. The data from the study suggested that fitness testing is merely an isolated part of physical education programs.  相似文献

The internal consistency and factorial validity of the 6-factor Scale of Coaching Performance (SCP; MacLean &; Chelladurai,1995) were examined using the responses of 448 administrators and coaches, randomly selected among NCAA programs. Confirmatory factor analysis, alpha coefficients, composite reliabilities, and variance extracted measures were utilized to test the internal consistency, reliability, and factorial validity of the SCP. The original 6-factor model was also tested against possible alternative models. The SCP had weak factor reliabilities: the public relations behaviors factor had an unacceptable reliability coefficient. The fit statistics (χ²p;= 2641.72; Scaled χ² = 2141.70, p < .001; RMSEA = .081; GFI = .74) indicated unsatisfactory factorial validity of the 6-factor model using the NCAA sample, because of problematic indicators and weak independence of latent variables but none of the alternative models provided better fit to the NCAA data. The SCP may be population-specific to the Canadian athletic system, which differs from the system found in the United States. Further analytic efforts are needed to improve the generalizability of SCP.  相似文献

This study aimed to provide further evidence of validity and reliability for the Physical Education Teacher Attitudes toward Fitness Tests Scale (PETAFTS), which consisted of affective and cognitive domains. There were two subdomains in the affective domain (i.e., enjoyment of implementing fitness tests and enjoyment of using test results) and one domain in the cognitive domain (i.e., beliefs in the usefulness of test results). Full-time physical education teachers (N?=?469) from two southwestern states in the United States participated in the study. Reliability and validity of the scale were examined. Alphas were computed for the entire 16-item scale, the affective and cognitive domains, and the two subdomains, respectively, to test the reliability. Confirmatory factor analysis (CFA) was employed to investigate the construct validity. The commonly used CFA indices, such as the chi square (χ2), the comparative fit index (CFI), the Tucker-Lewis Index (TLI), the goodness of fit index (GFI), and the root mean square error of approximation (RMSEA), were used to assess the fit of the data to the model. The CFA results suggested that the data from the study did not fit the original model proposed by Keating and Silverman (2004b) Keating, X. D. and Silverman, S. 2004b. Physical education teacher attitudes toward fitness test scale: Development and validation. Journal of Teaching in Physical Education, 23: 143–161. [Web of Science ®] , [Google Scholar], resulting in the elimination of item 3. The fitness of the data to the model was improved and deemed acceptable. More studies on the reliability and validity of the scale are needed in the future in order to use the scale with more confidence.  相似文献

The purpose of this study was to re-examine the factor structure of the Spectator Decision-Making Inventory through a confirmatory factor analysis. The inventory was developed by Zhang, Pease, Hui, and Michaud (1995), to measure factors affecting the attendance of men's professional basketball games, and consists of 15 items under 4 factors: Game Promotion, Home Team, Opposing Team, and Schedule Convenience. Spectators (N = 685), from 5 regular season home games of a National Basketball Association team, responded to the inventory. Procedures in the Windows LISREL 8.12 (Jöreskog & Sörbom, 1993a) computer program were utilized. The maximum likelihood estimation was adopted. With some minor respecifications by removing 2 items, the model provided a good fit to the data (e.g., RMSEA = .10, SRMR = .056, GFI = .90, CFI = .91), supporting a 4-factor structure. Researchers and practitioners may utilize the inventory to conduct in-arena or mail-out surveys.  相似文献

The purpose of this research was to amend the Vividness of Movement Imagery Questionnaire (VMIQ; Isaac, Marks, & Russell, 1986) in line with contemporary imagery modality and perspective conceptualizations, and to test the validity of the amended questionnaire (i.e., the VMIQ-2). Study 1 had 351 athletes complete the 3-factor (internal visual imagery, external visual imagery, and kinesthetic imagery) 24-item VMIQ-2. Following single-factor confirmatory factor analyses and item deletion, a 12-item version was subject to correlated traits / correlated uniqueness (CTCU) analysis. An acceptable fit was revealed. Study 2 used a different sample of 355 athletes. The CTCU analysis confirmed the factorial validity of the 12-item VMIQ-2. In Study 3, the concurrent and construct validity of the VMIQ-2 was supported. Taken together, the results of the 3 studies provide preliminary support for the revised VMIQ-2 as a psychometrically valid questionnaire.  相似文献

This study was designed to develop the Questionnaire Assessing School Physical Activity Environment (Q--SPACE) based on student perceptions. Twenty-eight items rated on 4-point Likert scales were administered to 244 middle school students in 9 schools. Exploratory factor analysis was used to evaluate the underlying structure of the items and 2 factors were extracted: physical environment (PE) and social environment (SE). Twelve and 8 items loaded saliently on PE (e.g., gym classes available) and SE (e.g., teacher encouragement), respectively. Factor scales had alpha coefficients of .86 (PE) and .81 (SE). One-week test–retest reliabilities for the factor scales of PE and SE were .78 and .72, respectively. Differences in PE scale scores across schools and PE and SE scale scores across student school physical activity behavior (e.g., participation on school teams) provided some evidence of scale construct validity. Overall, Q–SPACE demonstrates acceptable reliability for capturing middle school students' perceptions of school physical activity environment. The factorial validity needs to be assessed with confirmatory factor analysis and invariance testing procedures.  相似文献

The present study describes the development and validation of an instrument to measure volition in the exercise context. Volition describes an individual’s self-regulatory mental processes that are responsible for taking and maintaining a desirable action (e.g., exercising regularly). The scale structure was developed in an exploratory factor analysis which resulted in a reliable structure of the following six factors: Volitional Inhibition—Reasons, Volitional Inhibition—Postponing Training, Volitional Facilitation—Self-Confidence, Volitional Inhibition—Unrelated Thoughts, Volitional Inhibition—Approval From Others, and Volitional Facilitation—Coping with Failure. A sound theoretical explanation for these six factors is based on the Personal System Interaction Theory. This six-factor structure was also confirmed in a new sample in a confirmatory factor analysis, delivering an 18-item questionnaire with strong model fit and good internal consistency. In addition, the Volition in Exercise Questionnaire showed convergent validity because it was able to predict exercise participation. It showed incremental validity by explaining additional variance to the Sport Motivation Scale’s well-established predictors of exercise participation.  相似文献

The purpose of this study was to examine the validity of the Smarthealth watch (Salutron, Inc., Fremont, California, USA), a heart rate monitor that includes a wristwatch without an accompanying chest strap. Twenty-five individuals participated in 3-min periods of standing, 2.0 mph walking, 3.5 mph walking, 4.5 mph jogging, and 6.0 mph running. Heart rate was simultaneously measured and recorded at 60-sec intervals using three methods: the Smarthealth wristwatch, the Polar Vantage XL monitor with an accompanying chest strap (Kempele, Finland), and an electrocardiograph, which served as the criterion method. The heart rates obtained from the Smarthealth watch were highly correlated with those from the electrocardiograph (r ≥ .95) and the standard error of estimate was below 5 bpm for all measurements. Additionally, correlation coefficients and standard errors of estimate between the Smarthealth watch and Polar heart rate monitor were ≥.97 and <3.7 bpm, respectively. However, the Smarthealth watch exhibited a reduced ability to detect a heart rate during the 4.5 and 6.0 mph conditions compared to the Polar heart rate monitor (6% and 13.9% reduced ability, respectively). The Smarthealth watch appears to be a valid device for monitoring heart rate while standing and during treadmill exercise involving walking and jogging in a healthy young adult sample, although it may not be able to consistently detect a heart rate when body motion is excessive.  相似文献

The purpose of this study was to determine the effectiveness of a planned mastery motivational physical play session on physical activity (i.e., heart rate [HR] and physical play intensity [PAHR > 50]) in toddlers (N = 21), as compared to a nonplanned free play session. Participants wore a monitor to measure HR over two, 30 min play conditions. A multivariate analysis of variance was conducted to evaluate the effect of the play conditions. A significant difference between conditions and physiological measures revealed that the mastery motivational physical play session resulted in higher HR and PAHR > 50 when compared to free play. These findings suggest the mastery motivational session resulted in more vigorous physical play in toddlers than free play.  相似文献

The specific purposes of this study were (a) to identify the best mathematical model and the best data set for predicting men's future world-best track and field performance, (b) to predict ultimate performances for seven selected track and field events, and (c) to develop a new "random sampling" model to predict performance for those events that have exhibited asymptotic-like behavior over the last 15 years. Linear and nonlinear models were used to fit world record data and best performance per year data to identify the best fitting model. Extreme value theory and Monte Carlo simulation methods were used to derive predicted future performances under the random sampling model for the 1,500-m event. The results showed that (a) an exponential model relating running time and historical year with yearly best performance data is the most valid deterministic model for the prediction of world records and ultimate performance, and (b) the random sampling model is an effective method to predict future world records for the 1,500-m event, the only event to exhibit asymptotic performance over the last 15 years.  相似文献
