Insights
Home video recordings provide a reliable method for assessing infant gross motor development, comparable to in-person evaluations. This approach offers a convenient and low-burden alternative for parents in neonatal follow-up.
Area of Science:
- Pediatrics
- Developmental Pediatrics
- Neonatal Care
Background:
- Serial gross motor development assessment is crucial for high-risk infants in neonatal follow-up.
- Home video recordings present a potential complementary method for infant assessments.
Purpose of the Study:
- To evaluate the concurrent validity of using home video recordings for Alberta Infant Motor Scale assessments.
- To compare home video-based assessments with on-site evaluations by physical therapists.
Main Methods:
- The Alberta Infant Motor Scale was used to assess 48 infants (1.5-19 months).
- Assessments were conducted using both parent-made home videos and direct on-site observation by a pediatric physical therapist.
- Parental experiences with the video recording process were collected via questionnaire.
Main Results:
- High agreement (intraclass correlation coefficient = 0.99) was found between live and home video assessments.
- Intra- and interrater reliability for video assessments exceeded 0.99.
- 94% of parents found recording their infant's motor skills easy.
Conclusions:
- Assessing the Alberta Infant Motor Scale via home video recordings is a valid and reliable alternative to live observation.
- The home video method is a promising tool for infant motor development assessment, minimizing burden on families.
Purpose:
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.
