Insights
The Alberta Infant Motor Scale (AIMS) demonstrates high reliability and temporal stability in Serbian infants. This validated tool can effectively assess motor development in this population.
Area of Science:
- Pediatrics
- Developmental Pediatrics
- Motor Development Assessment
Background:
- The Alberta Infant Motor Scale (AIMS) is a widely used tool for assessing infant motor development.
- Validation of the AIMS in diverse populations is crucial for its global applicability.
- Assessing motor development in Serbian infants requires culturally adapted and validated tools.
Purpose of the Study:
- To evaluate the reliability, consistency, and temporal stability of the Serbian version of the Alberta Infant Motor Scale (AIMS).
- To establish a percentile distribution of AIMS scores for Serbian infants.
- To determine the suitability of the Serbian AIMS for clinical use in assessing infant motor development.
Main Methods:
- A prospective study involving 60 infants across three age groups (0-3, 4-7, 8-14 months).
- The Serbian AIMS was administered by two raters on two separate occasions (test-retest) with a 5-day interval.
- Inter-rater and intra-rater reliability were assessed using intraclass correlation coefficients (ICC).
Main Results:
- High inter-rater reliability (ICC > 0.75) was observed for most AIMS scores.
- High intra-rater reliability (ICC > 0.75) was found for most scores and raters.
- Moderate reliability was noted for specific items (standing, sitting) in certain age groups and between raters.
Conclusions:
- The Serbian version of the Alberta Infant Motor Scale (AIMS) exhibits high reliability and temporal stability.
- The AIMS demonstrates good consistency and can be reliably used to evaluate motor development in Serbian infants.
- The findings support the use of the Serbian AIMS for clinical assessment and research purposes.
Abstract:
Our study aimed to analyze the reliability, consistency, and temporal stability of the Alberta Infant Motor Scale (AIMS) in Serbian infants. Additionally, we aimed to present a percentile distribution of AIMS in the tested population. The prospective study included 60 infants that were divided into three age groups: 0-3 months, 4-7 months, and 8-14 months. The Serbian version of AIMS was tested by two raters on two different occasions (test/retest) with a five day period between tests. The observed inter-rater reliability (intraclass correlation coefficient (ICC)) was more than 0.75 for all AIMS scores, except for standing (ICC 0.655 = moderate) in the age group of 4-7 months on retest between raters. The observed intra-rater reliability (ICC) was more than 0.75 for all AIMS scores except standing (ICC 0.655 = moderate) in the age group 4-7 months in test-retest for Rater One, and for sitting (ICC 0.671 = moderate) and standing (ICC 0.725 = moderate) in the age group between 0-3 months on test-retest for Rater Two. The Serbian version of AIMS was shown to have high consistency and high reliability with good to high temporal stability. Thus, it can be used in the evaluation of infants' motor development in Serbia.
