Left/right judgement (LRJ) of body parts is commonly used to assess the ability to perform implicit motor imagery and the integrity of brain-grounded maps of the body. Clinically, LRJ are often undertaken using a mobile tablet, but the concurrent validity and reliability of this approach has not yet been established.
To evaluate the concurrent validity and test-retest reliability of a mobile tablet for assessing LRJ.
Participants completed LRJ for 50 hand images (Experiment 1), and 40 back, foot, or neck images (Experiment 2) using a mobile tablet and desktop computer in random order. Participants in Experiment 2 performed a repeat test the following day to assess test-retest reliability. Accuracy and response time (RT) were recorded.
Twenty participants aged 55.3 (±6.7) years in Experiment 1, and 37 participants aged 38.2 (±12.3) years in Experiment 2, were recruited. Concurrent validity of the mobile tablet was good to excellent for hand judgements (ICC = 0.836 for RT; ICC = 0.909 for accuracy), and was good for back, foot, and neck judgements (ICC = 0.781 for accuracy; ICC = 0.880 for RT). Test-retest reliability of the mobile tablet was good to excellent (ICC = 0.824 for accuracy; ICC = 0.903 for RT).
The mobile tablet demonstrated good to excellent concurrent validity with the desktop computer in two separate samples. The mobile tablet also demonstrated good to excellent test-retest reliability. The mobile tablet for LRJ is a valid alternative to the original desktop version.
身体部位的左右判断（LRJ）常用于评估执行内隐运动意象的能力和身体的大脑基础图谱的完整性。临床上，LRJ 通常使用移动平板电脑进行，但这种方法的同时效度和可靠性尚未确定。
评估用于评估 LRJ 的移动平板电脑的同时效度和重测信度。
参与者使用移动平板电脑和台式计算机以随机顺序完成了 50 个手图像的 LRJ（实验 1），以及 40 个背部、脚部或颈部图像的 LRJ（实验 2）。实验 2 的参与者在第二天进行重复测试，以评估重测信度。记录准确性和反应时间（RT）。
实验 1 招募了 20 名年龄为 55.3（±6.7）岁的参与者，实验 2 招募了 37 名年龄为 38.2（±12.3）岁的参与者。移动平板电脑对手部判断的同时效度为良好至优秀（RT 的 ICC=0.836；准确性的 ICC=0.909），对背部、脚部和颈部判断的同时效度为良好（准确性的 ICC=0.781；RT 的 ICC=0.880）。移动平板电脑的重测信度为良好至优秀（准确性的 ICC=0.824；RT 的 ICC=0.903）。
移动平板电脑在两个独立的样本中与台式计算机具有良好至优秀的同时效度。移动平板电脑还表现出良好至优秀的重测信度。用于 LRJ 的移动平板电脑是原始桌面版本的有效替代方案。
