Model for measuring teenagers’ alcohol consumption intent

© 2015 Sociedad Interamericana de Psicologia. All rights reserved. The objective of this study was to evaluate the empiric sustainability of a measurement model for the intent and risk of alcohol consumption among teenagers with a reduced number of items. We studied a non-probabilistic sample of 838 public high school students for this research. We carried out an exploratory factor analysis using the maximum likelihood method of extraction and the oblimin rotation. The evidence of data adequacy shows a rate of KMO.90 and a meaningful Bartlett's test of sphericity (X²=4774.8, gl=72, p=.000) which holds the adequacy and reliability of.90 with Cronbach's alpha. The empiric validity of the model is established (X²=35.4, gl=26, p<.05; CMIN/gl= 1.36; CFI=.998; NFI=.993; GFI=.991; AGFI=.985; RMSEA=.028), by structural equations as a corroborative method. The proposed method holds the appropriate parameters for a sustainable manner of assessing the intent of alcohol consumption in teenagers.
