The purpose of this article is to discuss some concerns with the Game Performance Assessment Instrument (GPAI). This review of the GPAI includes five perceived problems with the GPAI scoring and coding system: (1) calculation of individual and overall game performance indices, (2) use of game involvement versus game performance index to analyze game performance, (3) observer reliability, (4) nonlinearity, and (5) usefulness of action. In this article, we suggest a reexamination of the GPAI scoring and coding system that will lead to more efficient use of this game performance instrument. Some of the suggested modifications can be implemented quickly, whereas others need further research.
