Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate whether the prevention program Kapot Sterk is effective.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Given the growing concerns about youth's involvement in criminal behavior, there is a strong need for effective interventions to prevent it. However, knowledge about the effectiveness of prevention programs for juveniles is currently lacking. Incredibly Strong (translate as Kapot Sterk) is a prevention program designed to improve self-esteem, self-control, and resistance to peer pressure among pupils in elementary schools. By enhancing these social-emotional skills, the program ultimately aims to reduce youths' vulnerability to recruitment and involvement in criminal activities. The effects of Incredibly Strong on juvenile delinquency and other life domains are investigated, using a randomized controlled trial (RCT).

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

A cluster RCT will be used to determine the effectiveness of the program Incredibly Strong. Within each school, classes will be randomly assigned to either the experimental group, in which the program starts as soon as possible, or to a waitlist control group, which starts after the follow-up period (three months). Randomization to either the experimental or control group will take place using a computerized randomization in a 1:1 ratio. Classes in the waitlist control group receive the program approximately 5 months later, but still within the same school year, allowing all classes to receive the program.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

experimental group

This group will participate in the program Kapot Sterk.

Group Type EXPERIMENTAL

Kapot Sterk (translate as Incredibly Strong)

Intervention Type BEHAVIORAL

The program consists of five lessons of approximately 60 minutes long, delivered over a period of four to eight weeks. The lessons are facilitated by trained pedagogical staff (e.g., youth workers), while the school's own teachers are always present during the sessions. Lessons include active learning strategies such as role-playing, group discussions, and reflection exercises, often based on realistic and recognizable scenarios. The program focuses on strengthening key social-emotional skills, such as self-esteem, self-control, and resistance to peer pressure.

control group

This group will not participate in the program. They will receive the program afterwards, once data collection is finished.

Group Type NO_INTERVENTION
