Insights
This study found that the analysis of measurement instruments in pediatric research needs improvement. Key areas for enhancement include indicator selection, factor analysis application, and model fit to ensure reliable and valid psychometric scales.
Area of Science:
- Psychometrics
- Pediatric Research
- Statistical Analysis
Context:
- Latent construct measurement scales are widely used in medical literature.
- Ensuring the reliability and validity of these instruments is crucial for accurate interpretation.
- Psychometric instrument validation studies in pediatrics require rigorous methodological and statistical adherence.
Purpose:
- To evaluate compliance with methodological and statistical premises in pediatric psychometric instrument validation studies.
- To identify areas for improvement in the analysis of measurement scales.
- To provide recommendations for future research in pediatric psychometrics.
Summary:
- A review of 25 articles from Spanish pediatric journals (2000-2023) using factor analysis for scale validation was conducted.
- Key areas for improvement identified include reflective/formative indicators, indicator selection, scale validity linked to model fit, reliability assessment (Cronbach's alpha), and factor analysis techniques.
- The study highlights the need for enhanced analysis processes, particularly in indicator specification and factor analysis application.
Impact:
- Findings will guide researchers in improving the quality of psychometric instrument validation in pediatrics.
- Enhanced validation practices will lead to more reliable and interpretable results from pediatric studies.
- Recommendations aim to strengthen the methodological rigor of future research utilizing measurement scales in child health.
Abstract:
The use of latent construct measurement scales is widespread in the medical literature. An essential condition is that the instrument be validated, in addition to being highly reliable.
Objective:
To evaluate the level of compliance with various methodological and statistical premises of validation studies of psychometric instruments in pediatrics, which are necessary to ensure adequate interpretation of the results, in order to offer recommendations for future research.
Methods:
Articles published in two of the most prestigious journals in Spanish (Andes Pediatrica and Anales de Pediatría) were identified between December 2000 and December 2023, where factor analysis was performed on the items of measurement scales, and in which the reliability and validity of these scales were studied. Twenty-five articles that met the selection criteria were selected and compared with the analysis procedure recommendations.
Results:
Five key points were identified to improve: 1) Reflective and formative indicators; 2) Determination of the best reflective indicator; 3) Validity of a scale linked to the fit of the theoretical model; 4) Reliability using Cronbach's alpha; 5) Factor analysis versus principal components. Factor rotation.
Conclusions:
The analysis processes of measurement instruments in pediatrics must be improved, especially regarding the selection and specification of indicators, the use of factor analysis, and the fit of the proposed models.
