Validez y fiabilidad de una herramienta para determinar la etapa de cambio de comportamiento en relación al consumo diario de 5 porciones de frutas y hortalizas en adultos

Abstract

Fruits and vegetables are a fundamental part of a healthy diet, however, in Argentina, their consumption has decreased significantly in recent decades. In order to generate strategies to guide the process of nutritional counseling, it was decided to evaluate the validity and reliability of a self-administered tool to determine the stage of behavior change, based on the Transheoretical Model, in relation to the daily consumption of 5 portions of fruits and vegetables. The tool showed a moderate temporal stability (kappa coefficient= 0.48) and the analysis of multiple comparisons determined significant differences between the stages of pre-contemplation and preparation with respect to those of action and maintenance. Also between the contemplation stage with respect to maintenance stage. This tool will allow for the classification of people according to the stage in which they find themselves and thus guide messages and strategies to promote the consumption of fruits and vegetables.
