Objective: The Fantastic lifestyle assessment questionnaire was designed to help healthcare physicians measure their patients' life-styles. This work was thus aimed at assessing the reliability and validity of the Fantastic questionnaire (version 3 translated into Spanish) on a group of Colombian adults.
Materials and methods: The questionnaire was administered to 550 people to fill out themselves. Measures of central tendency and dispersion were used for the domains and groups; internal consistency and inter-scalar correlation were calculated.
Results: It was found that the 25 items, and those grouped into 10 domains exceeded the proposed reliability standard (Cronbach α), being greater than 0.50 and 0.73, respectively. Inter-scalar correlation was good and acceptable in various categories of the Fantastic questionnaire (total cf domains), (r=0.19 to 0.79; p<0.01).
Conclusions: Fantastic questionnaire version 3 brings together some of the internal consistency and construct validity criteria. It is recommended that the questionnaire be used in primary healthcare and epidemiological studies.
