title: Concurrent validity and reliability of the Alberta Infant Motor Scale in infants at dual risk for motor delays.
abstract: Concurrent validity of scores for the Alberta Infant Motor Scale (AIMS) and the Peabody Developmental Gross Motor Scale-2 (PDGMS-2) was examined with a sample of 35 infants at dual risk for motor delays or disabilities. Dual risk was defined as low birthweight (<or= 1,500 g at birth) and environmental risk (children from low-income families). Measures were administered to participants during one visit to a high-risk, follow-up program. Pearson product-moment correlation coefficients were high (r= .90 to .97), with the highest correlation between PDGMS-2 locomotion subscale and AIMS total score. Correlation coefficients were lower for infants > 9 months of age. Novice examiners' scores on both measures closely approximated those of experienced examiners (ICC range = .98 to .99). The results support concurrent validity of the AIMS and PDGMS-2 for infants at dual risk and have implications for using the AIMS in high-risk follow-up programs, particularly in relation to evaluating functional components of motor performance and ease of administration.
