Examining the Psychometric Properties of the Model of Human Occupation Screening Tool—Japanese Version

Measurement Properties of Canadian Agility and Movement Skill Assessment for Children Aged 9-12 Years Using Rasch Analysis

The Canadian Agility and Movement Skill Assessment (CAMSA) was recently widely used to assess fundamental motor skills in children. Although the CAMSA is reported to be reliable and valid, its measurement properties are not clear. This study aimed to examine the measurement properties of the CAMSA in a sample of Chinese children using Rasch analysis. The study sample was from 1,094 children aged 9-12 years in Zunyi City, Guizhou Province. Descriptive data were analyzed using SPSS 24.0 software, and the dichotomous data were analyzed by Winsteps version 4.5.4 and Facets 3.67.1 software performing Rasch analysis. The present study investigated CAMSA measurement characteristics by Rasch analysis, including the reliability of the rating instrument, unidimensionality, item-fit statistics, and differential item functioning (DIF). Inter-rater reliability and retest reliability showed that the CAMSA had a good internal consistency. Rasch analysis indicated that the CAMSA was unidimensional, locally independent, and had a good item-fit-statistic. Additionally, the CAMSA displayed a good fit for the item separation index (12.50 > 2.0), as well as for item reliability (0.99 > 0.90). However, the item difficulty of the CAMSA did not fit well with personal ability, and a significant DIF was found across genders. In the Chinese children sample test, the CAMSA demonstrated appropriate goodness-of-fit validity and rater reliability. Thus, future research will explore item difficulty and person ability fit, as well as DIF across genders.

Examining the Structural Aspect of the Construct Validity of the Japanese Version of the Model of Human Occupation Screening Tool

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.
