Concurrent Validity Between Live and Home Video Observations Using the Alberta Infant Motor Scale
Serial assessment of gross motor development of infants at risk is an established procedure in neonatal follow-up clinics. Assessments based on home video recordings could be a relevant addition.Methods:
In 48 infants (1.5-19 months), the concurrent validity of 2 applications was examined using the Alberta Infant Motor Scale: (1) a home video made by parents and (2) simultaneous observation on-site by a pediatric physical therapist. Parents' experiences were explored using a questionnaire.Results:
The intraclass correlation coefficient agreement between live and home video assessment was 0.99, with a standard error of measurement of 1.41 items. Intra- and interrater reliability: intraclass correlation coefficients were more than 0.99. According to 94% of the parents, recording their infant's movement repertoire was easy to perform.Conclusion:
Assessing the Alberta Infant Motor Scale based on home video recordings is comparable to assessment by live observation. The video method is a promising application that can be used with low burden for parents and infants.
