Wisconsin has mandated minimal weight (MW) testing for high school wrestlers. In preparation, six MW predictions were cross-validated on 69 Wisconsin wrestlers (age 15.7±1.1 yrs, height 169.2±6.3 cm, weight 63.3±8.1 kg, percent fat 11.2±4.7%, and MW 58.9±6.9 kg). Minimal weight, defined as fat-free body/.93, determined by hydrostatic weighing (HW) and residual volume using 02 dilution, served as the criterion. Analyzed using repeated-measures ANOVA, statistically significant but clinically small (<1.3 kg) differences were shown in four of six predictions. Lohman 1, Lohman2, and Katch equations appear more appropriate with smaller mean differences, smaller total error, and higher correlations.

The current study presents the development process and initial validation of a measure designed for assessing psychological needs thwarting (frustration) in a secondary school physical education context (Psychological Needs Thwarting Scale in Physical Education, PNTSPE). Secondary school students (grades 7–9) from Hong Kong (N = 1258) were invited to participate in three studies. In Study 1, item generation and initial content validity of the PNTSPE were achieved. In Study 2, the factorial structure of the measure was tested using exploratory and confirmatory factor analysis. Internal consistency reliabilities of the subscales were also examined. In Study 3, the reliability and validity of the scores derived from the PNTSPE were further examined in an independent sample. Overall, the findings from the three studies provided initial psychometric evidence for the PNTSPE and suggested that the PNTSPE could be used as a valid and reliable measure to assess Hong Kong secondary school students’ psychological needs thwarting in physical education.

The purpose of this study was to determine whether the Physical Education Teacher Attitudes Toward Fitness Tests Scale (PETAFTS) produces reliable and valid scores. There were 4 stages and 4 sets of participants in the development of the PETAFTS. First, the domains of attitude were defined and cognitive and affective components were developed, organized, and validated. In the second stage, 134 full-time physical education teachers participated in a pilot study and PETAFTS was revised based on the information obtained. In the third stage, 28 teacher educators served on an expert panel and organized the items into domain areas. In the final stage, 322 physical education teachers from 10 states tested the revised PETAFTS. Based on the results, the PETAFTS was shortened by deleting and combining some of the items in subdomains; this resulted in a 16-item final version that, according to the indices, generates reliable and valid scores.

The purpose was to validate a self-efficacy (SE) instrument toward including students with disability in physical education (PE). Three scales referring to intellectual disabilities (ID), physical disabilities (PD), or visual impairments (VI) were administered to 486 physical education teacher education (PETE) majors. The sample was randomly split, and exploratory and confirmatory factor analyses (EFA and CFA, respectively) were conducted. After deleting items that did not meet inclusion criteria, EFA item loadings ranged from 0.53 to 0.91, and Cronbach’s alpha reliability was high (for ID = .86, PD = .90, and VI = .92). CFA showed that the ID scale demonstrated good goodness-of-fit, whereas in the PD and in the VI scales demonstrated moderate fit. Thus, the content and construct validity of the instrument was supported.

Structural equation modeling was used to test an extended version of the Kendzierski, Furr, and Schiavoni (1998) Physical Activity Self-Definition Model. A revised model using data from 622 runners fit the data well. Cross-validation indices supported the revised model, and this model also provided a good fit to data from 397 cyclists. Partial invariance was found across activities. In both samples, perceived commitment and perceived ability had direct effects on self-definition, and perceived wanting, perceived trying, and enjoyment had indirect effects. The contribution of perceived ability to self-definition did not differ across activities. Implications concerning the original model, indirect effects, skill salience, and the role of context in self-definition are discussed.

The contemporary sport fan has the ability to consume spectator sport through several means including event attendance, television and radio broadcasts, print publications, and Internet applications. Recently, an ancillary sport service, termed fantasy sports, has become one of the most popular activities among sport fans. As a result, the business of fantasy sports is booming. This study examined motivational dimensions underlying fantasy football participation from a Uses and Gratifications perspective. Utilizing Churchill’s (1979) five-step method for developing quality marketing measures, this study identified and validated three motivational dimensions: entertainment/escape, competition, and social interaction. The results suggest a pattern of fantasy football participation that is more purposeful and active than traditional media use. Discussed are the gambling associations, future research opportunities, and suggestions for developing fantasy football participation into a more creative and interactive marketing communication tool.

The series of related studies reported here describe the development and validation of the Organizational Stressor Indicator for Sport Performers (OSI-SP). In Study 1, an expert and usability panel examined the content validity and applicability of an initial item pool. The resultant 96 items were analyzed with exploratory factor analyses in Study 2, with the factorial structure comprising 5 factors (viz., Goals and Development, Logistics and Operations, Team and Culture, Coaching, Selection) and 33 items. Using confirmatory factor analyses, Studies 3 and 4 found support for the 5-factor structure. Study 4 also provided evidence for the OSI-SP’s concurrent validity and invariance across different groups. The OSI-SP is proposed as a valid and reliable measure of the organizational stressors encountered by sport performers.

The purpose of our study was to establish criterion-related validity and repeatability of a shoulder biomechanics testing protocol involving an electromagnetic tracking system (Flock of Birds [FoB]). Eleven subjects completed humeral elevation tasks in the sagittal, scapular, and frontal planes on two occasions. Shoulder kinematics were assessed with a digital inclinometer and the FoB. Intrasession and intersession repeatability for orthopedic angles, and humeral and scapular kinematics ranged from moderate to excellent. Correlation analyses revealed strong relationships between inclinometer and FoB measures of humeral motion, yet considerable mean differences were noted between the measurement devices. Our results validate use of the FoB for measuring humeral kinematics and establish our testing protocol as reliable. We must continue to consider factors that can impact system accuracy and the effects they may have on kinematic descriptions and how data are reported.

This study was conducted to validate the System for Observing Fitness Instruction Time (SOFIT) for measuring physical activity levels of high-school students. Thirty-five students (21 girls and 14 boys from grades 9-12) completed a standardized protocol including lying, sitting, standing, walking, running, curl-ups, and push-ups. Heart rates and Energy Expenditure, that is, oxygen uptake, served as concurrent validity criteria. Results indicate that SOFIT discriminates accurately among high-school students’ sedentary behaviors (i.e., lying down, sitting, standing) and moderate to vigorous physical activity behavior and is recommended for use in research and assessment of physical activity levels in physical education classes for this age group. Implications for use of SOFIT by both researchers and teachers in physical education are described, as well.

Two studies reported the development and validation of the Coping Function Questionnaire (CFQ) for adolescent sport participants. The purpose of the first study was to develop the CFQ and conduct preliminary item and scale analyses. The result was an 18-item CFQ, which assessed problem-focused, emotion-focused, and avoidance coping function. In the second study, confirmatory factor analysis with data from 344 male and 339 female adolescent sport participants showed the CFQ measurement model to be acceptable for both genders. Simultaneous group analysis demonstrated gender invariance for the CFQ measurement model. Convergent and divergent validity was supported by correlations between the CFQ and select coping scales from the COPE, the sport-modified COPE, and Life Situations Inventory. The CFQ appears to be a promising step toward measurement of coping function in adolescent sport samples.
