Test selection, adaptation, and evaluation: a systematic approach to assess nutritional influences on child...

Area of Science:

• Child Development
• Nutritional Science
• Psychometrics

Background:

• Standardized developmental tests often lack validity in developing countries.
• Nutrition intervention research requires contextually appropriate assessment tools.
• Adapting tests ensures accurate evaluation of developmental outcomes.

Purpose of the Study:

• To present principles for selecting, adapting, and evaluating developmental tests in resource-limited settings.
• To apply these principles in a nutrition trial on Lombok, Indonesia.
• To ensure valid assessment of child development in diverse populations.

Main Methods:

• Pilot testing and adaptation of developmental assessment tools for local context.
• Evaluation of psychometric properties, including convergent and discriminant validity.
• Regression analyses using maternal education, depression, and age as predictors.

Main Results:

• Adapted tests exhibited satisfactory psychometric properties.
• Maternal education significantly predicted most developmental scores.
• Maternal depression and age showed specific associations with socio-emotional and cognitive outcomes.

Conclusions:

• Methodological principles yielded contextually appropriate and informative developmental tests.
• This approach enhances the evaluation of nutrition interventions' impact on child development.
• Valid assessment tools are vital for identifying effective interventions in developing nations.
