The aim of this study was to identify psychological and related factors linked with drunkenness episodes in 1134 adolescent students in Guadalajara, Mexico. The study evaluated ten psychological and related factors. The outcome variable was the number of episodes of drunkenness in the last month. We found 26.5% more episodes of drunkenness in men. A logistic regression analysis indicated that factors associated with drunkenness were smoking, high self-esteem, high impulsiveness, low self-control, presence of daily stress and distant relationship with father. The study concluded that the psychological and related factors associated with drunkenness episodes were related to a highly impressionable omnipotence profile and emotional indifference, with excessive consumption of alcohol as a safety strategy.  http://www.scielo.org.co/scielo.php?script=sci_arttext&pid=S0121-54692018000100105&lang=pt
