Examination of a cut-off score to express the meaningful activity of people with dementia using iPad application (ADOC).

AbstractPurpose: To determine a quantifiable measure to identify patients with dementia who can choose an illustration of meaningful activity using an iPad application, Aid for Decision-making in Occupation Choice (ADOC). Method: We recruited 116 patients from 5 institutions in Japan. Occupational therapists interviewed patients with dementia to determine meaningful activities using ADOC. The most meaningful activity was confirmed by their primary caregivers. The cut-off was estimated from Mini-Mental State Examination (MMSE). Results: Receiver operating characteristic analysis indicated that an MMSE score of 8 was the cut-off for choosing meaningful activities using ADOC. Sensitivity and specificity was 91.0% and 74.1%, respectively, and the area under the curve value was 0.89. Conclusion: ADOC can provide individualized information regarding meaningful activities for patients with moderate dementia.Implications for RehabilitationAs dementia progresses, difficulty in expressing needs or desires regarding...
