The measurement of physical activity patterns has the potential to reveal underlying causes of changes in modifiable risk-factors associated with health and well-being. Accurate classification of physical activity (PA) in free-living situations requires the use of a validated measurement system to

This research describes the development and validation of a measure designed to assess feeling states that occur in conjunction with acute bouts of physical activity—the Exercise-Induced Feeling Inventory (EFI). The EFI consists of 12 items that capture four distinct feeling states: revitalization, tranquility, positive engagement, and physical exhaustion. The multidimensional structure of the EFI is supported by confirmatory factor analysis. The subscales have good internal consistency, share expected variance with related constructs, are sensitive to exercise interventions, and appear responsive to the different social contexts in which activity may occur. After describing the psychometric properties of the EFI, several directions for theory-based research are proposed.

Cardiorespiratory endurance is a component of health-related fitness. FITNESSGRAM recommends the Progressive Aerobic Cardiovascular Endurance Run (PACER) or One mile Run/Walk (1MRW) to assess cardiorespiratory endurance by estimating VO2 Peak. No research has cross-validated prediction models from both PACER and 1MRW, including the New PACER Model and PACER-Mile Equivalent (PACER-MEQ) using current standards. The purpose of this study was to cross-validate prediction models from PACER and 1MRW against measured VO2 Peak in adolescents. Cardiorespiratory endurance data were collected on 90 adolescents aged 13–16 years (Mean = 14.7 ± 1.3 years; 32 girls, 52 boys) who completed the PACER and 1MRW in addition to a laboratory maximal treadmill test to measure VO2 Peak. Multiple correlations among various models with measured VO2 Peak were considered moderately strong (R = .74–0.78), and prediction error (RMSE) ranged from 5.95 ml·kg-1, min-1 to 8.27 ml·kg-1.min-1. Criterion-referenced agreement into FITNESSGRAM’s Healthy Fitness Zones was considered fair-to-good among models (Kappa = 0.31–0.62; Agreement = 75.5–89.9%; F = 0.08–0.65). In conclusion, prediction models demonstrated moderately strong linear relationships with measured VO2 Peak, fair prediction error, and fair-to-good criterion referenced agreement with measured VO2 Peak into FITNESSGRAM’s Healthy Fitness Zones.

The Segal fatness-specific bioelectrical impedance (BIA) equations are useful for predicting fat-free mass (FFM). Stolarczyk et al, proposed a modified method of averaging the two equations for individuals who are neither lean nor obese, thus eliminating the need to know % BF a priori. To cross-validate this modification, we compared FFM determined using the averaging method versus hydrostatic weighing for 76 adults. Per the averaging method, accuracy for males was excellent (r = .91, SEE = 2.7kg, E = 2.7kg), with 78% of individuals within ± 3.5% BF predicted by hydrostatic weighing. Accuracy for females was lower (r = .88, SEE = 3.0kg, E = 3.1 kg), with %BF of 51% within ±3.5% of the reference method. The relative ease and practicality of the averaging method and the results of this study indicate this method may be useful with a diverse group.

This article presents the development and validation of the Aging Stereotypes and Exercise Scale (ASES), which measures different dimensions of aging stereotypes in the exercise domain. Drawing on past research on older adults’ perceived barriers to exercise, these dimensions include stereotypes about positive and negative exercise outcomes for older adults and about older adults’ psychological barriers to exercise (i.e., lack of self-efficacy and motivation). Four studies involving 714 participants examined the factorial structure and invariance, temporal stability, and external validity of the scale. The results supported a 3-factor model that was invariant across age. Age differences in stereotype content appeared, with older adults holding more positive stereotypes than younger adults. Also as predicted, the more older adults endorsed negative stereotypes, the lower their physical self-worth, self-rated health, and subjective age. Last, responses to the ASES appeared to be stable over a 6-wk period.

The purpose of this study was to design and validate the Basketball Offensive Game Performance Instrument (BOGPI) that assesses an individual player’s offensive game performance competency in basketball. Twelve physical education teacher education (PETE) students playing two 10-minute, 3 vs. 3 basketball games were videotaped at end of a basketball unit in one physical education teaching methods course. Two investigators independently coded each player’s offensive game behaviors with BOGPI. The interrater reliability of the BOGPI was 99% and the alpha reliability coefficient for the total scale of the BOGPI was .95. The content validity evidence of the BOGPI was established by six experienced experts’ judgment. The results of this study indicate that the BOGPI is a theoretically sound and psychometrically supported measure that can be used by researchers and teacher educators to assess the preservice teachers’ offensive game performance ability in basketball.

The purpose of this study was to develop and validate a sport-specific version of Nideffer’s (1976a) Test of Attentional and Interpersonal Style (TAIS), specifically in regard to the sport of basketball. Collegiate basketball players (N = 43) participated in the research, 20 males and 23 females. The subjects were administered two instruments, the original TAIS and the Basketball Concentration Survey (BCS). The items contained in the BCS were a conversion of the 59 pertinent items contained in the original. The instruments were administered early in the season and the results were correlated with nine seasonal performance variables ranging from field-goal percentage to total number of steals. The results show the BCS to have significant reliability as well as significantly accounting for performance variability. The BCS had highly significant correlations with seven of the nine performance variables.

The role of peers has been neglected in research on youth psychosocial development in sport. The purpose of the present study was to develop and validate a measure of youth sport friendship quality for the purpose of facilitating such research. Dimensions and higher order themes found in Weiss, Smith, and Theeboom’s (1996) qualitative study of sport friendships among children and adolescents, as well as a core set of items from previous research (Parker & Asher, 1993), were used to develop and refine items for a sport friendship quality scale. Over the course of three studies, content, factorial, and construct validity, as well as internal consistency and test-retest reliability, were demonstrated for the Sport Friendship Quality Scale (SFQS). Future research is recommended to examine the role of children’s sport friendship quality on psychosocial development in the physical domain.

This paper describes the development of a survey instrument to assess athletics donor motivation. An extensive literature review, followed by interviews with athletics donors, identified 14 dimensions of donor motivation. Expert review and field testing of potential survey items reduced the number of dimensions of athletics donor motivation to 12. The final instrument, Motivation of Athletics Donors (MAD-1), was pilot tested with a sample of donors from 10 NCAA Division I athletics programs. Eleven scales were validated using confirmatory factor analysis, scale reliabilities (Cronbach's alpha), and item-to-total correlations. These results (a) provide the foundation necessary for systematic study of athletics donor behavior utilizing social cognitive theory as the theoretical framework, and (b) support the use of the MAD-1 as a practical instrument for assessing the specific motivations of any particular donor group.
