| Research Abstract |
By literature review and a survey research with psychiatric institutions, we collected 133 assessment scales for OT. Analyzing the items, we constructed a two-phase theory of OT assessment that the OT assessment should be made for three domains (ADL, interpersonal relationship, and personal factors) of adaptive functions of psychiatric patients at two phases. The first phase is to assess the functions by observing patients at OT settings, while the second one is to make assessments by reasoning their functions in the social environments.
Based on the theory, we newly developed the Assessment System for Psychiatric OT (ASPOT), which consists of the OT Observational Assessment Scale (O Scale) and the Social Adaptive Functions Assessment Scale (S Scale). In order to examine the criterion-related and concurrent validities of ASPOT, we asked OTRs of 13 psychiatric institutions to rate their patients using ASPOT, obtaining the data of 184 patients. Compared with younger patients, outpatients,

and patients of milder symptoms, we found that older patients, inpatients, and patients of more severe symptoms were lower on the most subscales and higher on the conduct problem scales of ASPOT. The O scale significantly correlated with COTE and the S scale with the Care Assessment for Psychiatric Patients. These results established the validity of ASPOT.
Then, we asked pairs of OTRs at 11 psychiatric institutions to rate each patient using ASPOT, and we obtained the data of 100 patients. Alpha coefficients were more than.7 for all the subscales but advanced ADL, for which it was.63. And, we asked OTRs of 5 psychiatric institutions to rate each patient two times at an interval of 1 month and obtained the data for 24 patients. The test-retest correlations were more than.8 for all the subscales. These results indicate that ASPOT has a high level of reliability.
Further, we constructed a short version of ASPOT in which the number of items was reduced. Both validity and reliability were established for the version. And, using ASPOT, we investigated rater biases in the OT assessment and the effects of OT for psychiatric patients. Less
