In recent years, the evaluation of nutritional knowledge has been a topic of keen
interest among researchers in health sciences, and several studies continue to be
carried out that involve a relationship with other theoretical constructs or in which
nutritional knowledge can have an effect on the food behavior and eating habits of
a population, which generate other health problems. Therefore, its measurement must
be guaranteed through reliable and valid instruments. Reliability refers to the degree
of stability achieved in the results when a measurement is repeated under identical
conditions.

Validity refers to the precision with which an instrument measures a theoretical
concept or construct, which is corroborated by a process of analyzing the data using
sequential statistical methods.

With this perspective, we have read with interest a recent publication by Alkaed
et al,

and we believe that it is a contribution to the understanding and measurement of
nutritional knowledge in future research in the area of public health. However, some
important aspects of the study need to be clarified.To read this article in full you will need to make a payment
