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.

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 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 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.

This article outlines the development and validation of the Multidimensional Motivational Climate Observation System (MMCOS). Drawing from an integration of the dimensions of the social environment emphasized within achievement goal theory and self-determination theory (as assumed within Duda’s [2013] conceptualization of “empowering” and “disempowering” climates), the MMCOS was developed to enable an objective assessment of the coach-created motivational environment in sport. Study 1 supported the initial validity and reliability of the newly developed observation system. Study 2 further examined the interobserver reliability and factorial structure of the MMCOS. Study 3 explored the predictive validity of the observational system in relation to athletes’ reported basic psychological need satisfaction. Overall, the results of these studies provide preliminary support for the inter- and intraobserver reliability, as well as factorial and predictive validity of the MMCOS. Suggestions for the use of this observational system in future research in sport are provided.

This paper documents the development and validation of the three-factor Subjective Exercise Experiences Scale (SEES), a measure of global psychological responses to the stimulus properties of exercise. Two of these factors correspond to the positive and negative poles associated with psychological health, Positive Weil-Being and Psychological Distress, whereas the third factor represents subjective indicants of Fatigue. The three-factor structure originally established by exploratory factor analysis using young adults was also supported in middle-aged exercising adults using confirmatory factor analytic techniques. Moreover, convergent and discriminant validity for the SEES subscales was demonstrated by examining relations with measures of affect regularly employed in exercise domain. The SEES may represent a useful starting point for more thoroughly examining exercise and subjective responses at the global level, and these dimensions of the scale may represent possible antecedents of specific affective responsivity.

This investigation sought to determine if cycling power could be accurately modeled. A mathematical model of cycling power was derived, and values for each model parameter were determined. A bicycle-mounted power measurement system was validated by comparison with a laboratory ergometer. Power was measured during road cycling, and the measured values were compared with the values predicted by the model. The measured values for power were highly correlated (R 2 = .97) with, and were not different than, the modeled values. The standard error between the modeled and measured power (2.7 W) was very small. The model was also used to estimate the effects of changes in several model parameters on cycling velocity. Over the range of parameter values evaluated, velocity varied linearly (R 2 > .99). The results demonstrated that cycling power can be accurately predicted by a mathematical model.

The purpose of this article is to report on the development and validation of the Game Performance Assessment Instrument (GPAI). The GPAI is a multidimensional system designed to measure game performance behaviors that demonstrate tactical understanding, as well as the player’s ability to solve tactical problems by selecting and applying appropriate skills. The GPAI provides analyses of individual game performance components (e.g., decisions made, skill execution, and support) and/or overall performance (e.g., game involvement and game performance). The individual game performance components were developed and evaluated by experts to determine validity and reliability. The GPAI protocol was field tested across three categories of games: invasion (soccer and basketball), net/wall (volleyball), and field/run/score (softball). Validity and reliability were examined through three separate studies using middle school physical education specialists and their sixth-grade classes. Findings suggest that the GPAI provides a valid and reliable method for assessing game performance.

validated during a weight-loss study ( Williams, Grow, Freedman, Ryan, & Deci, 1996 ). To reduce item redundancy and for economical reasons, researchers have used adjusted versions with fewer items (see Kasser & Ryan, 1999 ; Williams et al., 1999 ; Williams, Freedman, & Deci, 1998 ). As the HCCQ is

The purpose of this study was to assess the criterion validity of existing accelerometer-based energy expenditure (EE) prediction equations among children with chronic conditions, and to develop new prediction equations. Children with congenital heart disease (CHD), cystic fibrosis (CF), dermatomyositis (JDM), juvenile arthritis (JA), inherited muscle disease (IMD), and hemophilia (HE) completed 7 tasks while EE was measured using indirect calorimetry with counts determined by accelerometer. Agreement between predicted EE and measured EE was assessed. Disease-specific equations and cut points were developed and cross-validated. In total, 196 subjects participated. One participant dropped out before testing due to time constraints, while 15 CHD, 32 CF, 31 JDM, 31 JA, 30 IMD, 28 HE, and 29 healthy controls completed the study. Agreement between predicted and measured EE varied across disease group and ranged from (ICC) .13–.46. Disease-specific prediction equations exhibited a range of results (ICC .62–.88) (SE 0.45–0.78). In conclusion, poor agreement was demonstrated using current prediction equations in children with chronic conditions. Disease-specific equations and cut points were developed.
