Reliability of observational measures of the Movement Assessment of Infants
Abstract:
This study was conducted to examine the reliability of the Movement Assessment of Infants (MAI), a recently published neuromotor assessment tool. Interobserver and test-retest reliability data were collected on 27 full-term and 26 preterm 4-month-old infants. Reliability coefficients (Pearson r) were calculated for both the total-risk scores and the section-risk scores on the MAI. The total-risk score was calculated by summing the questionable or abnormal ratings on each of the 65 test items. For each of the four sections of the test, tone, primitive reflexes, automatic reactions, and volitional movement, an individual section-risk score was computed in a similar manner. Fair reliability was demonstrated for the total-risk scores (interobserver: r = .72; test-retest: r = .76). Section-risk score coefficients yielded a wide range of values for both interobserver and test-retest reliabilities (poor to good reliability). These measures provide needed technical data for therapists using this test and will assist the authors of the MAI in their attempts to improve the clinical validity of this assessment tool.
Insights
This study assessed the Movement Assessment of Infants (MAI) reliability in 4-month-old infants. The MAI demonstrated fair interobserver and test-retest reliability for total-risk scores, with varied reliability for its sections.
Area of Science:
- Pediatric physical therapy
- Infant neuromotor development
- Clinical assessment reliability
Background:
- The Movement Assessment of Infants (MAI) is a new tool for evaluating infant neuromotor skills.
- Reliability data is crucial for validating new clinical assessment tools.
Purpose of the Study:
- To evaluate the interobserver and test-retest reliability of the Movement Assessment of Infants (MAI).
- To provide technical data for clinicians and MAI authors.
Main Methods:
- Collected interobserver and test-retest reliability data on 53 infants (27 full-term, 26 preterm) aged 4 months.
- Calculated Pearson correlation coefficients (r) for total-risk and section-risk scores on the MAI.
- Section-risk scores were computed for tone, primitive reflexes, automatic reactions, and volitional movement.
Main Results:
- Fair reliability was found for total-risk scores (interobserver: r = .72; test-retest: r = .76).
- Section-risk scores showed a wide range of reliability, from poor to good, for both interobserver and test-retest measures.
Conclusions:
- The MAI demonstrates acceptable overall reliability for total-risk scores in 4-month-old infants.
- Further refinement may be needed for specific sections to improve consistency.
- These findings offer essential technical data for MAI users and developers.
