# Creation and Validation of the Brief Healthy Eating Habits Scale (BHEHS-6B, Version 1.0), Based on Harvard’s Healthy Eating Plate, in a Sample of Young, Middle-Aged, and Older Peruvian Adults

## TL;DR

This study created and validated a short tool to assess healthy eating habits in Peruvian adults of different ages, based on Harvard’s Healthy Eating Plate.

## Contribution

The BHEHS-6B is a new, brief, and culturally adapted instrument for assessing healthy eating habits in Peruvian populations.

## Key findings

- The BHEHS-6B showed strong structural validity with acceptable fit indices and a unidimensional structure.
- The instrument demonstrated adequate internal consistency with a Cronbach's alpha of 0.769.
- The BHEHS-6B is suitable for use in public health research and policy due to its brevity and reliability.

## Abstract

Background. Healthy eating habits are essential for preventing chronic diseases and improving quality of life. However, there is a lack of brief and culturally adapted instruments for accurate assessment. Therefore, the aim of this study was to develop and validate the Brief Healthy Eating Habits Scale (BHEHS-6B, Version 1.0), based on Harvard’s Healthy Eating Plate, in a sample of young, middle-aged, and older Peruvian adults. Methods. The study followed a psychometric design. A non-probabilistic sample of 223 participants (both sexes; mean age = 41.6, SD = 15.8) was drawn from Metropolitan Lima, Peru. The BHEHS-6B (Version 1.0) was administered. Results. The bifactor model confirmed the unidimensional structural validity of the BHEHS-6B, showing acceptable global fit indices (CFI = 0.987, TLI = 0.937, SRMR = 0.025, RMSEA = 0.081) and an adequate hierarchical omega for the general factor (G = 0.638), supporting the use of a single total score. Finally, internal consistency was adequate for the total scale (α = 0.769, ω = 0.780). Conclusions. The BHEHS-6B is a valid and reliable instrument for assessing healthy eating habits, demonstrating evidence of strong content validity, internal consistency, and an adequate factor structure. Moreover, as a brief instrument, it is particularly useful for studies aiming to evaluate multiple variables and for the implementation of public health policies focused on improving community health.
