The triangle completion test has been used to assess egocentric wayfinding for decades, yet there is little information on its reliability. We developed a virtual reality (VR) based test and investigated whether either test of spatial navigation was reliable.
To examine test-retest reliability of the real-world and VR triangle completion tests. A secondary objective was to examine the usability of the VR based test.
Thirty healthy adults aged 18-45 years were recruited to this block randomized study. Participants completed two sessions of triangle completion tests in the real-world and VR on the same day with a break between sessions.
In both test versions distance from the endpoint and angle of deviation showed poor test-retest reliability (r < 0.5). Distance traveled had moderate reliability in both the real-world and VR tests ( = 0.55 95% CI [0.23, 0.76]; = 0.66 95% CI [0.4, 0.83, respectively]). The VR triangle test showed poor correlation with the real-world test.
The triangle completion test has poor test-retest reliability and demonstrates poor concurrent validity between the real-world and VR. Nevertheless, it was feasible to translate a real-world test of spatial navigation into VR. VR provides opportunities for development of clinically relevant spatial navigation tests in the future.
三角形完成测试已被用于评估以自我为中心的路径寻找能力数十年，但关于其可靠性的信息却很少。我们开发了一种基于虚拟现实（VR）的测试，并研究了这两种空间导航测试是否可靠。
检验现实世界和VR三角形完成测试的重测信度。第二个目的是检验基于VR的测试的可用性。
招募了30名年龄在18 - 45岁的健康成年人参与这项分组随机研究。参与者在同一天在现实世界和VR环境中完成两阶段的三角形完成测试，两阶段之间有休息时间。
在两个测试版本中，到终点的距离和偏差角度的重测信度都很差（r < 0.5）。在现实世界和VR测试中，行进距离的信度中等（分别为 = 0.55，95%可信区间[0.23, 0.76]； = 0.66，95%可信区间[0.4, 0.83]）。VR三角形测试与现实世界测试的相关性较差。
三角形完成测试的重测信度较差，且在现实世界和VR之间的同时效度也较差。然而，将现实世界的空间导航测试转化为VR测试是可行的。VR为未来开发临床相关的空间导航测试提供了机会。
