Theory of Planned Behavior and alcohol use in adolescents in Ecuador. Structural linear regression analysis

The general aim is to identify the explanatory potential of alcohol use intentions in drinking behaviors in a sample of adolescents in Ecuador. The method consists of a descriptive, explanatory, and crosssectional study using SEM techniques. The participants were 384 adolescents (57% male and 43% female), aged 14-18 years (M = 16.51; SD = 2.64), who are students attending between the 1st and 3rd year of high school in a public educational institution in Ambato, Ecuador. Like principal results, the presence of alcohol use intention is moderate; the practice of alcohol use is low and mostly does not represent a risk, although 3.9% of the participants could report significant problems with consumption. Intentionality and drinking covary positively with low and moderate intensity. Drinking Intentionality explained 15.3% of the variance of drinking. We conclude that the Alcohol Use Intentions are a predictor of adolescent drinking behaviors.
