Summary
The Infant Motor Profile (IMP) demonstrates good interobserver reliability and strong concurrent validity with neurological exams. Its performance domain shows the best correlation with the Alberta Infant Motor Scale (AIMS).
Area of Science:
- Pediatric neurology
- Developmental pediatrics
- Motor development assessment
Background:
- The Infant Motor Profile (IMP) is a qualitative tool assessing infant motor behavior across five domains.
- Reliability and validity are crucial for clinical assessment tools in pediatrics.
Purpose of the Study:
- To evaluate the interobserver reliability of the IMP.
- To determine the concurrent validity of the IMP against the Alberta Infant Motor Scale (AIMS) and an age-specific neurological examination.
Main Methods:
- Fifty-nine preterm and 146 term infants were assessed at corrected ages of 4, 6, 10, 12, and 18 months.
- Assessments included the IMP, AIMS, and a neurological examination.
- Interobserver reliability was tested on 25 video recordings.
Main Results:
- The IMP showed high interobserver reliability (ICC=0.95).
- Concurrent validity with AIMS was moderate to strong for the IMP's performance domain (ρ=0.47-0.84).
- A significant relationship was found between total IMP scores and neurological examination outcomes (p<0.001).
Conclusions:
- The IMP is a reliable tool for assessing infant motor behavior.
- The IMP's performance domain is a valid measure when compared to the AIMS.
- The IMP demonstrates very good concurrent validity with standard neurological assessments.
