Purpose: To examine whether the Canadian normative values of the Alberta Infant Motor Scale (AIMS) are appropriate for Dutch infants. Method: In a cross-sectional study, 499 infants developing typically (0.5-19 months) were assessed using the AIMS home video method. The scaling method was used for calculating item locations of the Dutch sample, and Welch test to compare Canadian and Dutch raw scores. Results: The AIMS items (45 of 58) met the criterion for stable regression to calculate item locations of the Dutch data set and compare these with the Canadian data set. Dutch infants passed 42 of 45 items at an older age. Most monthly age groups of Dutch infants had lower mean AIMS scores. Conclusion: The Canadian norms are not appropriate for the Dutch study sample. Dutch infants appear to develop in a similar sequence but at a slower rate. This has implications regarding the clinical use of the AIMS in the Netherlands.
