Insights
The Milani-Comparetti Motor Development Screening Test shows acceptable interobserver and test-retest reliability for children aged 1-16 months. Further evaluation is needed for its use in predicting or monitoring developmental delays.
Area of Science:
- Pediatric physical therapy
- Developmental pediatrics
- Motor development assessment
Background:
- Reliability of developmental screening tools is crucial for accurate clinical assessment.
- The Milani-Comparetti Motor Development Screening Test is used to evaluate motor skills in young children.
- Establishing the psychometric properties of screening tests ensures their validity and utility.
Purpose of the Study:
- To assess the interobserver and test-retest reliability of the Milani-Comparetti Motor Development Screening Test.
- To determine the consistency of scoring by different examiners and over time.
- To provide evidence for the clinical utility of this motor development screening tool.
Main Methods:
- Sixty healthy children aged 1-16 months were videotaped during the Milani-Comparetti test administration.
- Four pediatric physical therapists independently scored the videotaped responses to assess interobserver reliability.
- Forty-three children were retested within one week to evaluate test-retest reliability using percentage agreement and Kappa statistics.
Main Results:
- Interobserver agreement ranged from 79% to 98%, with significant G statistics for all items.
- Test-retest agreement ranged from 80% to 100%.
- Excellent test-retest reliability (Kappa > 0.75) was found for 82% of items, with good reliability for the rest.
Conclusions:
- The Milani-Comparetti Motor Development Screening Test demonstrates acceptable interobserver and test-retest reliability for the assessed age group.
- The findings support the use of the test as a reliable screening tool for motor development.
- Further research is recommended to evaluate its predictive and follow-up capabilities in at-risk populations.
Abstract:
The purpose of this study was to determine the level of interobserver and test-retest reliability of the Milani-Comparetti Motor Development Screening Test. Sixty healthy children, aged 1 through 16 months, were videotaped during administration of the Milani-Comparetti test. Four pediatric physical therapists independently viewed each videotape and scored the responses. Interobserver reliability was determined by calculation of percentage of agreement and the G statistic between a primary observer and each therapist. Forty-three children were retested within one week by the initial tester to examine test-retest reliability. Test-retest reliability was determined by percentage of agreement of items between the two test sessions and using the Kappa statistic. Interobserver percentage of agreement for the individual items on the Milani-Comparetti test ranged from 79% to 98%. The G statistic was significant for all items indicating the high percentage-of-agreement values were not due merely to chance agreement. Test-retest agreement ranged from 80% to 100%. Using Kappa statistic guidelines, excellent test-retest reliability (K greater than .75) was found for 82% of the test items, with good reliability of the remaining items. Acceptable interobserver and test-retest reliability was found for all items on the Milani-Comparetti test. Use of the Milani-Comparetti test as a clinical screening tool for prediction or follow-up of motor development in children at risk for developmental delays requires further evaluation.
