Instrument Design and Validation to Asses the Perception of Wellbeing Associated to Plain Water.

Nowadays, it is common to ingest beverages other than plain water, which range from flavored with a low energy input to others of high input. In Mexico, flavored beverage ingestion is believed to be displacing plain water; this phenomenon is raising concern in the health sector, due to the relation between flavored beverage intake and the increase in obesity and, consequently, chronic diseases. Up until now, there is no instrument available to characterize the perception of the Mexican population\'s well-being, beliefs and knowledge regarding plain water ingestion, nor is there an instrument capable of quantifying the daily water ingestion. The purpose of this study is design and validate a questionnaire to identify and evaluate the perception of well-being (PWBQ) related to plain water consumption in a sample of adult men and women of the city of Cuernavaca.
