Summary
This systematic review found that psychometric measures for assessing children's occupational performance lack consistent validity evidence. Many studies used incomplete or outdated validation techniques, highlighting a need for more robust methods like factor analysis.
Area of Science:
- Occupational Therapy
- Psychometrics
- Child Development
Background:
- Ensuring the psychometric quality of instruments used by health professionals is crucial, especially concerning validity evidence.
- Instruments assessing occupational performance in children require rigorous validation.
Purpose of the Study:
- To analyze the psychometric measures employed in studies evaluating the validity evidence of instruments for assessing occupational performance in children with developmental coordination disorder.
Main Methods:
- A systematic review adhering to Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines.
- Searches were conducted across five electronic databases.
Main Results:
- Twenty-four articles featuring 17 distinct scales were included.
- Discriminant validation was the most common measure, with half of the studies using parametric and nonparametric analyses.
- Reliability analysis (Cronbach's alpha, test-retest) was most prevalent; factor analysis for internal structure was underutilized.
Conclusions:
- Validation techniques varied, were often incomplete, and sometimes confusing.
- Contemporary validity evidence concepts were infrequently addressed.
- Factor analysis for internal structure, though rarely reported, is a robust validation technique that warrants greater use.
