摘要
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.
