Brief Summary

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.

Study Arms (2)

SCPP-YA group

EXPERIMENTAL

SCPP-YA adapted to Chile consist of ten sessions promoting self-regulation strategies, prosocial, and problem-solving skills. It also includes a module (6 sessions) specially designed for substance use prevention, developing social competence, and assertiveness to deal with peer pressure. These 16 sessions will be implemented during an academic year (2020), and complemented with three booster sessions the following year (2021).

Behavioral: SCPP-YA

Control Group

NO INTERVENTION

The control schools will continue providing their traditional preventive actions.

Interventions

SCPP-YABEHAVIORAL

SCPP-YA includes two modules. In the first module of ten sessions, students will learn to employ a 6-step social information processing framework for solving a wide range of real-life problems. The six-step process consists of 1) stop, clam down, and think before you act; 2) say the problem and how you feel; 3) set a positive goal; 4) think of many solutions; 5) think ahead to the consequences and 6) go ahead and try the best plan. The second module offers 1) current and accurate information about the health, social, and legal consequences of substance use, 2) correct mistaken beliefs that students have about substance use, 3) enhances awareness of social and media influences; and 4) teachers assertiveness and critical thinking skills to resist peer pressure.

Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Schools having primary education (Year 1 to Year 8)
  • Schools located in Santiago (Chile)
  • Schools having a vulnerability index (School Vulnerability Index - National System of Equality Allocation (IVE-SINAE)) ≥ 50%\*
  • Mixed-sex schools.
  • Schools willing to participate under the conditions of the study before randomization.
  • The IVE-SINAE is built taking into account several students' and parental variables: health, family income, receiving state benefits. This percentage means the proportion of students in a school who are in most need.

You may not qualify if:

  • \. Schools that are implementing other substance use prevention program similar to the contents and methodology of "Mi Mejor Plan" targeting the same grade.
