BACKGROUND: Very low birth weight (VLBW) infants are at increased risk for motor deficits, which may be reduced by early intervention programs. For detection of motor deficits, and to monitor intervention, different assessment tools are available. It is important to choose tools that are sensitive to evaluate the efficacy of intervention on motor outcome. OBJECTIVE: The purpose of this study was to compare the Alberta Infant Motor Scale (AIMS) and the Psychomotor Developmental Index (PDI) of the Bayley Scales of Infant Development-second edition (BSID-II) in their ability to evaluate effects of an early intervention, provided by paediatric physical therapists, on motor development in VLBW infants at 12 months corrected age (CA). DESIGN: This was a secondary study in which data collected from a randomized controlled trial (RCT) were used. METHODS: At 12 months CA, 116 of 176 VLBW infants, participating in a RCT on the effect of the Infant Behavioral Assessment and Intervention Program, were assessed with both the AIMS and the PDI. Intervention effects on the AIMS and PDI were compared. RESULTS: Corrected for baseline differences, significant intervention effects were found for AIMS and PDI scores. The highest effect size was for the AIMS subscale sit. A significant reduction of abnormal motor development in the intervention group was only found with the AIMS. LIMITATIONS: No Dutch norms are available for the AIMS. CONCLUSIONS: The responsiveness of the AIMS to detect intervention effects was better than the PDI. We therefore recommend caution with monitoring VLBW infants only with the PDI and advise to use both the AIMS and the BSID when evaluating intervention effects on motor development at 12 months CA.
