Resumen
HERNANDEZ-LOPEZ, Edgar Armando y DE-BLAS-RANGEL, Aida del Refugio. Reliability and construction analysis of the FANTASTIC MEX-A instrument to measure the lifestyle of mexican adults. Bicentric pilot study in a headquarters and a private university. Rev. sanid. mil. [online]. 2023, vol.77, n.2, e01. Epub 29-Sep-2023. ISSN 0301-696X. https://doi.org/10.56443/rsm.v77i2.326.
Objective:
To carry out a reliability and construct analysis of the FANTASTIC MEX-A instrument through Cronbach's alpha (α) and exploratory factor analysis (EFA) in two Mexican institutions located in the state of Guerrero: a general headquarters and a private university, such as a pilot study to determine the feasibility of performing it on a large scale in Mexican adults.
Design:
Quantitative, cross-sectional, non-experimental, descriptive. Simple random sampling. Data collection from February 2021 to November 2022. Variables: Lifestyle level (dependent); occupation, gender, education, marital status, type of family, age and body mass index (attributive).
Results:
N=493, n=242, 49% participation (NC=95%, CI=4.5%), the sample consisted of 204 military personnel and 38 university teachers/administrators. Cronbach's alpha=0.869 (good), using the two-half method, α=0.76 was obtained for odd items and α=0.762 for even items, rho correlation between halves of 0.903 (strong correlation). Mean score obtained of 134.8 ± 17.7 points, equivalent to 72.5%. Nine factors with theoretical association were found, that explain 42.64% of the accumulated variance in the Exploratory Factor Analysis (EFA), 1: The protection of mental health and physical integrity, 2: Distress, 3: Affective interpersonal relationships, 4: The consumption of alcohol and substances of abuse, 5: Physical activity and associativity, 6: Tobacco consumption, 7: Sleep and diet, 8: Health control and 9: Physical appearance.
Conclusions:
Through the Cronbach's Alpha statistic by the two-half method, it was concluded that the FANTASTIC MEX-A instrument is consistent for the sample studied. The AFE determined construct validity for nine factors with theoretical association.
Limitations:
The study was conducted in the state of Guerrero, México, the validation of the instrument in Mexican adults requires a representative sample that considers subjects from various regions of the country.
Originality:
There are no publications that standardize the available versions of the instrument in Spanish. A unique version is provided that involved the revision and reconstruction of each item with supporting illustrations.
