The Motivation Rating Scale (MRS) and General Trait Rating (GTRS) Scales have been proposed as methods for assessing personality traits of athletes. The scales are easily accessible and are proposed for use as coaching tools. A coach's form and athlete's form of each test was administered to 149 male and female varsity high school basketball players and their coaches in eight different states. Means and standard deviations for all variables as well as test-retest reliability coefficients, trait inter-correlations, correlations between test forms, and Alpha coefficients were calculated. Results suggest that each of the four scales was independent of the others, with the coach's form of the MRS showing reasonable reliability and reasonable internal consistency for selected traits. There is some indication that "trait generalization" among coaches may inflate the test-retest reliability of the coach's form of the MRS. No convincing evidence is presented to support the notion that any of the four scales measure the traits the scales are purported to measure.
动机评定量表（MRS）和一般特质评定量表（GTRS）已被提议作为评估运动员人格特质的方法。这些量表易于获取，并被提议用作教练工具。对来自八个不同州的149名男女高中校队篮球运动员及其教练进行了每个测试的教练版和运动员版测试。计算了所有变量的均值和标准差，以及重测信度系数、特质间相关性、测试版本间的相关性和阿尔法系数。结果表明，四个量表中的每一个都相互独立，MRS的教练版在所选特质上显示出合理的信度和合理的内部一致性。有迹象表明，教练之间的“特质泛化”可能会夸大MRS教练版的重测信度。没有令人信服的证据支持这一观点，即四个量表中的任何一个能够测量其声称要测量的特质。
