Aims of this study are to analyze the relationship among attachment styles,early maladaptive schemas, and substance use; test the predictive role of attachment styles on substance use; and observe themediating role of early maladaptive schemas in the relationship between attachment and substance use. The sample consisted of1533 adolescents from Ecuador (53.9% males) aged between 14 and 18 years (M = 15.76; SD = 1.25). The attachment styles of security, value to parental authority, parental permissiveness, parental interference, self-sufficiency and resentment against parents,childhood trauma, and family concern predict substance use (tobacco, alcohol, tranquilizers/sedatives or sleeping pills, hashishor marijuana, cocaine, GHB or liquid ecstasy, ecstasy, amphetamines/speed, hallucinogens, heroin, inhalants/volatiles), and themediating role of early maladaptive schemas is confirmed (explained variance up to 33.33%). Identifying risk or vulnerabilityfactors, such as attachment and early maladaptive schemas related to substance consumption, is especially relevant for designingand implementing preventive interventions in the adolescent population.
