Purpose: In this study, we used the Japanese version of the Allen Cognitive Level Screen-5（ACLS-5） manual to determine its validity for use among occupational therapists in Japan by examining the relationship between the test results of the ACLS-5 in terms of the Mini Mental State Examination-Japanese, Functional Independence Measure, and bed-fast scale.
Methods: We determined the Spearman’s rank correlation between the ACLS-5 and the bed-fast scale（widely used in Japan to assess activities of daily living）, the Functional Independence Measure（FIM）, and the Mini Mental State Examination-Japanese（MMSE-J）, which is used to measure cognitive function. In addition, we used the MMSE scores to divide the subjects into two groups: a healthy group with no cognitive problems （total MMSE-J≧28） and a group with cognitive problems（total MMSE-J≦27）. With our criterion variable thus set, we adjusted the ACLS-5 scores and added gender and age values, then performed a logistic regression analysis using the likelihood ratio test to ascertain the percentage of correct classifications（p ＜ 0.05）.
Results: Our ACLS-5 measurement results were significantly correlated with the total bed-fast scale scores（ρ＝0.46）, total MMSE-J scores（ρ＝0.54）, and total FIM scores（ρ＝0.47）. In the logistic regression analysis, our ACLS-5 results were significant in terms of determining the presence or absence of cognitive problems, with a solid percentage of correct classifications（ 74.5％）.
Conclusion: The measurement results for ACLS-5 and other evaluation methods obtained in this study confirm the validity of ACLS-5 for clinical use in Japan.
