SILVA, Jaqueline Garcia da et al. Psychometric properties of Self-Efficacy to Regulate Eating Habits (SEREH) scale. Rev Esp Nutr Hum Diet [online]. 2019, vol.23, n.1, pp.14-26.  Epub 29-Jun-2020. ISSN 2174-5145.  http://dx.doi.org/10.14306/renhyd.23.1.627.

Introduction

The aim of this study was to describe the preliminary psychometric properties of the “Self-Efficacy to Regulate Eating Habits (SEREH)”.

Material and Methods

Participated in a randomized clinical trial for lifestyle modification 135 subjects with metabolic syndrome, who were divided into two groups (e.g., experimental and control), in a 18-months follow-up. The evaluation included anthropometric, clinical, psychological and lifestyle data. To verify the validity and reliability, a factorial analysis was performed, as well as analyses of the internal consistency, temporal stability, sensitivity to change, and convergent validity.

Results

A solution with two factors was extracted, which explained 60.97% of the variance of the SEREH. The internal consistency for the total score was 0,971 - Cronbach’s alpha. Regarding temporal stability, no changes were observed during the follow-up in the control group. With regard to sensitivity to change, the experimental group showed greater self-efficacy than did the control group during the follow-up.

Conclusions

These preliminary results showed adequate psychometric properties of the scale, demonstrating that this is a valid and reliable scale for assessing self-efficacy related to food behaviors.
