Insights
The Turkish version of the Peabody Developmental Motor Scale-2 (PDMS-2) is a reliable and valid tool for assessing motor development in at-risk infants aged 0-24 months in Turkey.
Area of Science:
- Pediatric developmental psychology
- Infant neurodevelopmental assessment
- Psychometric validation studies
Background:
- Accurate assessment of motor development in at-risk infants is crucial for early intervention.
- The Peabody Developmental Motor Scale-2 (PDMS-2) is a widely used tool, but its Turkish version requires validation.
- Understanding the psychometric properties of the PDMS-2 in the Turkish population is essential.
Purpose of the Study:
- To investigate the construct and concurrent validity of the Turkish version of the PDMS-2.
- To assess the reliability of the Turkish PDMS-2 in at-risk infants.
- To determine if the Turkish PDMS-2 is a suitable measure for neurodevelopmental assessment in this population.
Main Methods:
- 120 at-risk infants (0-24 months) in Turkey participated.
- Construct validity was assessed via confirmatory factor analysis.
- Concurrent validity was examined using correlations with the Alberta Infant Motor Scale and Hammersmith Infant Neurological Examination.
- Test-retest reliability was evaluated using Cronbach's alpha and intraclass correlation coefficient (ICC).
Main Results:
- The Turkish PDMS-2 demonstrated acceptable construct validity (GFI=0.951, RMSEA=0.021).
- Concurrent validity was confirmed with significant correlations (r=0.502-0.771, p < .05).
- High reliability was found for the overall scale (Cronbach's α = 0.865) and subdimensions (ICC FMQ: 0.998, ICC GMQ: 0.998).
Conclusions:
- The Turkish version of the PDMS-2 exhibits good psychometric properties.
- The PDMS-2 is a reliable and valid instrument for assessing neurodevelopmental aspects in Turkish at-risk infants.
- This validated tool can aid in early identification and intervention for motor delays in Turkish infants.
Abstract:
This study was designed to investigate the construct-concurrent validity and reliability of the Turkish version of the Peabody Developmental Motor Scale-2 (PDMS-2) in at-risk infants between 0-24 age in Turkey. In this study, 120 infants (70 males, 50 females) participated in the study (mean corrected age 20.18 ± 22.535 weeks). The PDMS-2 scale consists of two subdimensions, the Fine Motor Quotient (FMQ) and the Gross Motor Quotient (GMQ). Whereas the construct validity was assessed using confirmatory factor analysis, concurrent validity was investigated using the correlation between PDMS-2 and the Alberta Infant Motor Scale and the Hammersmith Infant Neurological Examination with Spearman's correlation analysis. The PDMS-2 was applied twice for test-retest reliability. Cronbach's alpha (α) and the intraclass correlation coefficient (ICC) were used for reliability. ICC value was with 95% CI. The overall reliability coefficient of the test was found to be Croncbach's α = 0.865. TICC values were found (ICC FMQ: 0.998, ICC GMQ: 0.998). Construct validity (/SD = 4.396; root mean square error of approximation = 0.021; goodness-of-fit index = 0.951) and concurrent validity (r = 0.502-0.771; p < .05) were confirmed as acceptable. The PDMS-2 demonstrated good psychometric properties and can be used as a reliable and valid measure to assess neurodevelopmental aspects of Turkish at-risk infants.
