An Investigation of the Test-Retest Reliability of the miniPXI

The miniPXI serves as a short-form instrument designed to measure player experience, yet its utility for longitudinal or repeated evaluations remains limited.

• The miniPXI is reliable for tracking high-level metrics like overall enjoyment, appreciation, and Net Promoter Score, but it lacks the psychometric precision required for complex dimensions like immersion and mastery.
• Multi-item frameworks such as PXI, PENS, GEQ, and AttrakDiff consistently outperform the miniPXI in capturing nuanced player experience data.
• The study evaluated the miniPXI’s stability over a three-week interval using a sample of 100 participants across four distinct game genres.
