Preliminary Development and Evaluation of the Mini Player Experience Inventory (mPXI)

Abstract

Measuring player experience (PX) is key in most game user research. Recently, the Player Experience Inventory (PXI) was presented, a validated 30-item survey instrument using a 7-point Likert scale. The issue with this instrument is that with 30 items it is too long for research studies for which PX is one of the measures. We present in this work-in-progress paper the mPXI or the mini Player Experience Inventory, a 10-item survey instrument. We evaluated the mPXI with an educational game used in engineering education (n = 169). While further evaluation of the mPXI is needed, the current results show promise for using a shortened version of the original PXI.

miniPXI: Development and Validation of an Eleven-Item Measure of the Player Experience Inventory

“…Researchers also found it difficult to integrate the scale in more comprehensive evaluations of serious games [11,103]. As a result, preliminary attempts have been made to formulate a shorter variant with only one item per construct [48].…”

“…Yet, the length of player experience questionnaires can also be a barrier toward wider uptake [51]. Anecdotal accounts from game studios as well as requests from academic scholars highlight the need for a shorter version [48]. Moreover, in light of the widespread adoption of the System Usability Measure (SUS)-a 10-item small scale for rapid evaluation of perceived usability [19], the 11-item scale for analyzing player experience may prove useful for the GUR community.…”

“…First efforts toward the creation of shortened variants of existing player experience questionnaires have been made. Most prominently, Harteveld et al [48] investigated the potential of a shortened version of the PXI. Using only one item instead of three for each dimension, they evaluated an educational game used in engineering education.…”

Can you spot the difference?: learning about different Greek art periods through serious games

“…I employ post-semi-structured surveys for qualitative analysis to assess player engagement in both the control and experimental groups. Furthermore, for this quantitative research, I use the mini-Player Experience Inventory (mPXI) [11] post-surveys [12] with a Likert scale [13] to assess whether playing a serious game with or without entertainment elements is beneficial for the player's learning outcome. In addition, we use an independent t-test on the means of the gathered data to see if there is a significant difference between selected PXI constructs and learning outcomes when participants play the control and experimental games.…”

Balanced CCG design based on mathematical model

“…The questionnaire design (Appendix B) refers to the Player Experience of Need Satisfaction (PENS) (Scott Rigby& Richard Ryan, 2007) and mPXI (Mini Player Experience Inventory) (Harteveld et al, 2020). The player experience can be divided into five dimensions, including competence, autonomy, immersion, feedback and satisfaction.…”
