The Performance Index Evaluation (PIE) is a basketball-specific assessment of physical performance. The battery consists of items typically included in sport assessments, such as agility and power, but also addresses an often-overlooked performance component, namely, core strength. The purpose of this study was to examine the reliability (test-retest, interrater), validity (criterion-related, construct-related), and practice effect of the PIE among men's and women's college basketball players. Test-retest estimates were moderate for men (intraclass correlation coefficient [ICC] = 0.79) and poor for women (ICC = 0.35), but interrater reliability was high (ICC = 0.95). Criterion-related validity evidence (i.e., relationship between PIE and playing time) was weak, but construct-related evidence was acceptable (i.e., college players had higher scores than high school players). A practice effect was also demonstrated among men. In conclusion, reliability of the battery should be improved before its use is recommended among college basketball players. Additionally, the battery does not appear to be a predictor of performance but does appear to distinguish between skill levels.
性能指数评估（PIE）是一项针对篮球运动的身体性能评估。该测试组合包含了运动评估中常见的项目，如敏捷性和力量，但也涉及到一个常被忽视的性能组成部分，即核心力量。本研究的目的是检验PIE在男女大学生篮球运动员中的信度（重测信度、评分者间信度）、效度（效标关联效度、结构关联效度）以及练习效应。重测估计值男性为中等（组内相关系数[ICC]=0.79），女性较差（ICC=0.35），但评分者间信度较高（ICC=0.95）。效标关联效度证据（即PIE与上场时间之间的关系）较弱，但结构关联效度证据是可接受的（即大学生球员得分高于高中生球员）。男性中也显示出练习效应。总之，在建议大学篮球运动员使用该测试组合之前，应提高其信度。此外，该测试组合似乎不是表现的预测指标，但似乎能区分技能水平。
