Cross-Cultural Assessment of Functional Ability

Abstract
Culture and environment are known to influence performance of activities of daily living. Few functional assessments currently used in rehabilitation address the issue of cultural validity or relevance of the tasks that are used for assessment purposes. The Assessment of Motor and Process Skills (AMPS) addresses this problem by allowing the client to chose assessment tasks that are more relevant in their daily lives. We investigated the cross-cultural validity of the AMPS by contrasting test performance in subjects from two countries: the United States and Sweden. Data on 589 North American and Swedish subjects were submitted to Rasch analysis, and the results supported the validity of the AMPS in each country. Of the 35 AMPS items, only one item, Endures, differed significantly between the two samples. Overall item stability across samples indicated that the results obtained in both countries could be compared in a valid and meaningful way.
