Abstract
OBJECTIVES: The purposes of this study were to examine the cross-cultural validity of the Assessment of Motor and Process Skills (AMPS) as well as the reliability of raters from different cultures. METHOD: Six trained raters from diverse cultural backgrounds scored 10 Japanese subjects' performances on familiar and culturally relevant tasks of their own choosing. RESULTS: Results indicated high cross-cultural validity and interrater reliability for the AMPS, as indicated by goodness of fit of subjects and raters via the many-faceted Rasch measurement model. The relative rater severity was also evaluated cross-culturally by the standardized difference (z). The Japanese rater and one of the three American raters varied significantly in severity between their scoring of Japanese subjects versus European subjects. CONCLUSION: The results support the hypothesis that the AMPS can be used as a cross cultural instrumental activities of daily living assessment. Further study is needed to clarify the issue of possible cultural bias in rater severity.
