Alcohol use and risk factors for self-harm behavior in Spanish adolescents.

Self-harm behaviors in children and adolescents constitute an important public health problem with prevalence figures in the clinical population between 40 and 80%. The objectives of the study were to analyze and compare the Spanish sub-samples of two studies, SEYLE and WE-STAY to determine prevalence, self-harm patterns and factors associated with self-harm behaviors, notably the use of alcohol or drugs. The questionnaires used in both studies were the Global School Health Survey (GSHS), the Beck Depression Inventory (BDI-II), the Strengths and Difficulties Questionnaire (SDQ).
