Insights
The Test of Infants' Daily Living Activities (IDLA) accurately identifies motor developmental delays in infants, showing high agreement with the Alberta Infant Motor Scale (AIMS). This tool is valuable for screening neurodevelopmental disorders early.
Area of Science:
- Pediatric Development
- Neurodevelopmental Disorders
- Clinical Diagnostics
Background:
- Delayed psychomotor development in infants can signal increased risk for developmental disorders.
- Early functional diagnostics are crucial for identifying developmental abnormalities and initiating specialized neurodevelopmental assessments.
- The Test of Infants' Daily Living Activities (IDLA) was developed to aid in this early identification process.
Purpose of the Study:
- To assess the construct validity of the Test of Infants' Daily Living Activities (IDLA).
- To demonstrate the concurrent validity of the Test of IDLA against the Alberta Infant Motor Scale (AIMS).
- To determine the predictive value of the Test of IDLA for infant postural and motor control development.
Main Methods:
- The study involved 357 infants aged 1-18 months.
- Participants were evaluated using the Alberta Infant Motor Scale (AIMS) and the Test of IDLA, which includes postural and motor control assessments.
- Data analysis involved correlation coefficients (Spearman's rho, Cramer's V), chi-square tests, and ROC curve analysis.
Main Results:
- A statistically significant positive correlation (rho = 0.72, p < 0.0001) was found between the Test of IDLA and the AIMS scale.
- A very strong relationship was confirmed by Cramer's V = 0.78 and chi-square analysis.
- The Test of IDLA demonstrated very good diagnostic capability (AUC = 0.928) with stable and repeatable results.
Conclusions:
- The Test of IDLA shows high concordance with the AIMS scale in detecting motor developmental delays in infants.
- The findings support the utility of the Test of IDLA for screening neurodevelopmental disorders.
- The Test of IDLA is a reliable tool for assessing postural and motor control in infants.
Background:
Delays in psychomotor development in children could be an early indicator of elevated risk for developmental disorders. Early functional diagnostics enables the identification of abnormalities in various developmental domains and contributes to the initiation of specialized neurodevelopmental diagnostics. The objective of this study was to assess the construct and concurrent validity of the Test of Infants' Daily Living Activities. The focus was on identifying the construct validity of the Test of IDLA, demonstrating the concurrent validity of the Test of IDLA in relation to the Alberta Infant Motor Scale, as well as determining the predictive value of the Test of IDLA in assessing the development of postural and motor control in infants.
Methods:
The study included 357 children aged 1-18 months. Each child was thoroughly evaluated using the AIMS scale, in accordance with the methodology of the diagnostic tool's usage, and the Test of IDLA, which involved a postural control assessment sheet and a motor control evaluation sheet.
Results:
Comparison of Test of IDLA results with the reference AIMS scale demonstrated a statistically significant, positive correlation, with Spearman's rank correlation coefficient rho = 0.72, p < 0.0001. A very strong relationship between both scales was also indicated by the Cramer's V result = 0.78 and χ2 (1, n = 357) = 217.518. The area under the ROC curve value (AUC = 0.928) indicated very good diagnostic capability of the Test of IDLA. The narrow confidence interval (0.897-0.953) and low standard error (0.0147) emphasized the stability and repeatability of Test of IDLA results under clinical conditions.
Conclusion:
The Test of IDLA demonstrates high concordance with the reference AIMS scale in identifying motor developmental delays in children, in the domains of postural control and motor control. These findings indicate the utility of the Test of IDLA in the screening identification of neurodevelopmental disorders.
