The objective of this work was to reconstruct the Tower of London (TOL) test in order to increase its reliability. A three-phase process was undertaken to accomplish this goal. In Phase 1, the TOL item pool was increased, the task was administered to a sample of college students (N = 50), and item-total correlations were calculated in order to identify the items that had the highest correlation with the total score. In Phase 2, the revised 30-item TOL (TOL-R) was administered to a second sample (N = 50) and the internal consistency reliability (Chronbach alpha) was estimated at. 794. Finally, Phase 3 examined the test-retest reliability of the TOH-R on a new sample (N = 34) and the stability was found to be acceptable at r =.70.
这项工作的目的是重建伦敦塔（TOL）测试，以提高其可靠性。为此采取了一个三阶段的过程。在第一阶段，增加了TOL项目库，将该任务施测于一组大学生样本（N = 50），并计算项目与总分的相关性，以识别与总分相关性最高的项目。在第二阶段，将修订后的30个项目的TOL（TOL-R）施测于第二个样本（N = 50），估计内部一致性信度（克朗巴赫α系数）为0.794。最后，在第三阶段，对一个新样本（N = 34）检验了TOL-R的重测信度，发现稳定性在r = 0.70时是可接受的。
