Abstract
The original version of the Cambridge Prospective Memory Test (CAMPROMPT) was translated into Japanese with authorization from the original authors. The Japanese version of CAMPROMPT was given to 242 healthy control subjects and 57 clinical subjects with brain injury. The reliability of the Japanese version was then studied. Regarding inter-rater reliability, the concordance rate of the scores of 1 tester and 4 other scorers was 98.2％ and the significant correlation with 1 tester and 4 other scorers (1 scorer：Spearman's ρ = 0.986, 3 scorers: Spearman's ρ = 1.000) showed that the scoring system was highly reliable. Regard ing parallel form reliability, the correlation between versions (Spearman's ρ = 0.537) showed either ver sion could be used without being affected by the results of the other version. Regarding internal consis tency, Cronbach's α = 0.849 of the clinical subjects and Cronbach's α = 0.817 of the healthy control subjects showed the 6 subtests could examine consistent ability at prospective memory in all subjects. To standard ize the battery, norms were calculated within four age groups. From these reliability studies, we confirmed that the Japanese version of CAMPROMPT is able to test prospective memory ability reliably.
