Sponsor's own description

Substance use has become a significant public health problem, given its magnitude and the treatment gap encountered when a dependency disorder has already been installed. Still, to date, there are no studies in Chile that show the effectiveness of a universal preventive program implemented in educational settings, using a randomized controlled clinical trial design.

This study consists of evaluating the effectiveness of the Social Competence Promotion Program among Young Adolescents (SCPP-YA), which aims to postpone the onset of substance use and reduce their consumption.

This is a randomized controlled clinical trial with two arms, including students of 6th grade from high socioeconomic vulnerability schools in Santiago. The primary outcome is the incidence of tobacco consumption in the last month.

The SCPP-YA consists of 16 sessions that will be implemented during the academic year (2020) and complemented with three booster sessions the following year (2021). This intervention mainly provides strategies for self-regulation, problem-solving, and substance use prevention.

The investigators expect that students in the intervention group will delay the onset of any substance use, especially tobacco, alcohol, and marijuana when compared with students in the control group.
