Inter- and Intra-Reliability Data

The present study sought to assess and establish the reliability of a bespoke coding window to assess volleyball performance. This coding window was the first to combine a six-phase model of complexes along with efficacy scales that were individualised to each of the six key skills (Serve, Serve Receive, Set, Spike, Block, and Defence). The results of the study demonstrated Kappa and Weighted Kappa values above the acceptable thresholds for both inter- and intra-reliability, and that it was possible to utilise such a detailed system without the impact of Observer Drift.

本研究旨在评估并确立一款用于排球运动表现分析的定制化编码窗口的信度。该编码窗口为首款结合六阶段复合动作模型与针对六项核心技能定制化效能评定量表的分析工具，六项核心技能分别为发球（Serve）、接发球（Serve Receive）、二传（Set）、扣球（Spike）、拦网（Block）与防守（Defence）。本研究结果显示，卡帕系数（Kappa）与加权卡帕系数（Weighted Kappa）均达到了评定者间信度与评定者内信度的可接受阈值以上，且该系统可在不受观察者漂移影响的前提下实现精细化应用。
