Myers, Nicholas D.; Brincks, Ahnalee M.; Beauchamp, Mark R. – Measurement in Physical Education and Exercise Science, 2010
The primary purpose of this tutorial is to succinctly review some options for, and consequences of, centering Level 1 predictors in commonly applied cross-sectional two-level models. It is geared toward both practitioners and researchers. A general understanding of multilevel modeling is necessary prior to understanding the subtleties of centering…

Myers, Nicholas D.; Ahn, Soyeon; Jin, Ying – Research Quarterly for Exercise and Sport, 2011
Monte Carlo methods can be used in data analytic situations (e.g., validity studies) to make decisions about sample size and to estimate power. The purpose of using Monte Carlo methods in a validity study is to improve the methodological approach within a study where the primary focus is on construct validity issues and not on advancing…

Myers, Nicholas D.; Chase, Melissa A.; Beauchamp, Mark R.; Jackson, Ben – Educational and Psychological Measurement, 2010
The purpose of this validity study was to improve measurement of athletes' evaluations of their head coach's coaching competency, an important multidimensional construct in models of coaching effectiveness. A revised version of the Coaching Competency Scale (CCS) was developed for athletes of high school teams (APCCS II-HST). Data were collected…

Myers, Nicholas D.; Feltz, Deborah L.; Wolfe, Edward W. – Research Quarterly for Exercise and Sport, 2008
This study extended validity evidence for measures of coaching efficacy derived from the Coaching Efficacy Scale (CES) by testing the rating scale categorizations suggested in previous research. Previous research provided evidence for the effectiveness of a four-category (4-CAT) structure for high school and collegiate sports coaches; it also…

Myers, Nicholas D.; Feltz, Deborah L.; Chase, Melissa A.; Reckase, Mark D.; Hancock, Gregory R. – Educational and Psychological Measurement, 2008
The purpose of this validity study was to improve measurement of coaching efficacy, an important variable in models of coaching effectiveness. A revised version of the coaching efficacy scale (CES) was developed for head coaches of high school teams (CES II-HST). Data were collected from head coaches of 14 relevant high school sports (N = 799).…

Myers, Nicholas D.; Wolfe, Edward W.; Maier, Kimberly S.; Feltz, Deborah L.; Reckase, Mark D. – Research Quarterly for Exercise and Sport, 2006
This study extended validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS; Myers, Feltz, Maier, Wolfe, & Reckase, 2006) by examining use of the original rating scale structure and testing how measures related to satisfaction with the head coach within teams and between teams.…

Myers, Nicholas D.; Feltz, Deborah L.; Maier, Kimberly S.; Wolfe, Edward W.; Reckase, Mark D. – Research Quarterly for Exercise and Sport, 2006
This study provided initial validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS). Data were collected from intercollegiate men's (n = 8) and women's (n = 13) soccer and women's ice hockey teams (n = 11). The total number of athletes was 585. Within teams, a multidimensional…

Myers, Nicholas D.; Wolfe, Edward W.; Feltz, Deborah L.; Penfield, Randall D. – Measurement in Physical Education and Exercise Science, 2006
This study (a) provided a conceptual introduction to differential item functioning (DIF), (b) introduced the multifaceted Rasch rating scale model (MRSM) and an associated statistical procedure for identifying DIF in rating scale items, and (c) applied this procedure to previously collected data from American coaches who responded to the coaching…

Myers, Nicholas D.; Wolfe, Edward W.; Feltz, Deborah L. – Measurement in Physical Education and Exercise Science, 2005
This study extends validity evidence for the Coaching Efficacy Scale (CES; Feltz, Chase, Moritz, & Sullivan, 1999) by providing an evaluation of the psychometric properties of the instrument from previously collected data on high school and college coaches from United States. Data were fitted to a multidimensional item response theory model.…
