Abstract

Objective: To evaluate cross-regional validity of the Assessment of Motor and Process Skills (AMPS) with a specific focus on valid use with Middle Europeans.
Design: Descriptive cross-regional validation study.
Participants: A total of 1346 participants from Middle Europe and 144,143 participants from North America, UK/Ireland, the Nordic Countries, other Europe, Australia/New Zealand and Asia, between the ages of 3 and 103 years, in good health and with a variety of diagnoses, were selected from the AMPS database.
Methods: Many-facet Rasch analysis was used to analyse participant raw data, and effect sizes were used to evaluate for differential item functioning. Evaluation for differential test functioning was also implemented.
Results: None of the 20 activity of daily living process items, and only one of the activity of daily living motor items
demonstrated differential item functioning. The activity of daily living motor item Aligns exceeded the significant effect size criterion of ± 0.55 logit, but the significant differential item functioning did not lead to differential test functioning (i.e. all measures fell within the 95% confidence bands).
Conclusion: This study provides further evidence of validity of the AMPS when used to evaluate quality of daily living performance across world regions. The AMPS measures can be used as objective indices of activity of daily living ability in rehabilitation settings and in international collaborative research related to activity of daily living task performance.
