Summary
A 16-item food behavior checklist (FBC) was developed with strong psychometric properties, including validity and reliability. This brief, easy-to-administer tool is suitable for community health promotion interventions.
Area of Science:
- Nutrition science
- Psychometrics
- Health behavior research
Background:
- Dietary behavior assessment is crucial for public health.
- Existing tools may be lengthy or lack robust psychometric validation.
- Developing concise, reliable instruments is essential for effective interventions.
Purpose of the Study:
- To evaluate psychometric properties of food behavior checklist (FBC) items.
- To systematically reduce the FBC item count based on psychometric data.
- To create a brief, validated tool for assessing food behaviors.
Main Methods:
- Assessed 6 psychometric properties of FBC items.
- Utilized random assignment for intervention and control groups.
- Focused on women (N=132) from limited-resource families in low-income communities.
Main Results:
- The fruit and vegetable subscale demonstrated acceptable criterion validity (r=.44).
- Nineteen items showed acceptable reliability, and 11 items were sensitive to change.
- The final 16-item FBC is easy to administer with a fourth-grade reading level.
Conclusions:
- A brief, 16-item food behavior checklist (FBC) exhibits strong validity, reliability, and sensitivity.
- The FBC is suitable for diverse populations and community health promotion.
- This study provides a model for refining health assessment instruments.
