Objective/Background The Model of Human Occupation Screening Tool-Japanese version (J-MOHOST) was developed, and it was identified that the J-MOHOST did not have any problems in linguistic validation. The purpose of this study is to examine the psychometric properties of the J-MOHOST for the physical disabilities. Methods Forty-four participants were recruited from the rehabilitative wards and data, including demographic variables and the J-MOHOST scores, were obtained. The fit statistics, rating scale characteristics, and reliability index were examined using the Rasch analysis. Results There were no misfitting participants, and the J-MOHOST measures reliably separated the participants into 3.95 statistically distinct strata with a person reliability of .88. The result of item fit showed that it did not have noticeable problem in the items of the J-MOHOST. Moreover, the item reliability was .88. The content of the item difficulty could represent the characteristics of occupational participation of the participants in conformity with the rating system of the J-MOHOST. Conclusion The J-MOHOST rating scale could discriminate the level of occupational participation in physical disabilities. The results indicate that the J-MOHOST is an effective tool for measurement. Further studies are needed to increase the number of participants with a variety of disabilities and settings.

Model of HumanOccupation, Japanese version of the Model of Human Occupation Screening Tool, occupational participation.Introduction: The purpose of this study was to clarify the structural aspect of the construct validity of the Japanese version of the Model of Human Occupation Screening Tool.Method: The Japanese version of the Model of Human Occupation Screening Tool was examined using a Rasch model and confirmatory factor analysis. Demographic variables and scores on the Japanese version of the Model of Human Occupation Screening Tool and the Functional Independence Measure were retrieved from 115 clients in rehabilitation wards.Findings: The results of our study indicate that the Japanese version of the Model of Human Occupation Screening Tool effectively assesses clients' ability to engage in activities of daily living and their occupational participation as a dynamic process of engaging in these activities. The level of correlation between the Japanese version of the Model of Human Occupation Screening Tool and the Functional Independence Measure indicates that the former is able to effectively evaluate occupational participation. The structure of the items within the Japanese version of Model of Human Occupation Screening Tool was found to be commensurate with the structure of the Model of Human Occupation.Conclusion: The Japanese version of Model of Human Occupation Screening Tool is a useful assessment tool for assessing occupational participation.

Introduction Authors created an Occupational Identity Questionnaire Provisional version (OIQ-P) to assess occupational identity for elderly individuals. The purpose of this study was to examine the psychometric properties of the OIQ-P. Methods Participants included 135 (42 males) elderly who lived locally and required care or support. OIQ-P was evaluated in terms of structural validity, criterion validity and internal consistency. Results Based on the results of an exploratory factor analysis and confirmatory factor analysis, an OIQ with a factor structure of 3 factors and 14 items was created. Rasch rating scale model revealed that 14 participants and 1 item did not fit the goodness of fit, nevertheless, the overall result was good. Spearman's rank correlation coefficient indicates that there was a law correlation between OIQ and the occupational identity scale of the Occupational Performance History Interview Version 2. In terms of internal consistency, the person separation index and person separation reliability coefficient were 2.30 and 0.84, respectively. Conclusion This study confirmed the structural validity, criterion validity and internal consistency for the OIQ. To enhance the clinical utility of the OIQ, it is necessary to examine the interpretability and conduct an intervention study using the OIQ.
