Early interventions benefit the mental health, academic performance and productivity of children and adolescents throughout their life. The present study protocol will evaluate the effectiveness of the Elos 2.0 Programme, which is a version adapted for Brazil by the Ministry of Health, in reducing problem behaviours (e.g., disruptiveness, aggressivity and shyness) and promoting social skills in the school context in children 6 to 10 years of age. The Elos Programme is based on the Good Behaviour Game, which is widely used and prevents and/or reduces students' disruptive behaviours by establishing cooperation contingencies.
A cluster-randomized controlled trial will be performed in 30 schools in three cities (15 controls and 15 in the experimental group), with a total of 3800 children participating in the test (1900 in the control group and 1900 in the intervention group). Data will be collected by having teachers in the control and experimental classes complete the Teacher Observation of Classroom Adaptation (TOCA) questionnaire, which is an instrument used to observe children's behaviour in the classroom. We will collect data before and after the intervention period in the same year. Due to the hierarchical structure of the data, multilevel analysis will be performed to detect simultaneous differences in prevalence over time and across groups to control for sociodemographic variables.
The current study will examine the effectiveness of the Elos 2.0 Programme in reducing problem behaviours (e.g., disruptiveness, aggressivity and shyness) and promoting social skills in the school context. The findings of this school-based prevention programme for children will influence the development and implementation of similar programmes for schools and educational policymakers by identifying mechanisms that are central to achieving positive outcomes for participants.

早期干预有益于儿童和青少年的心理健康、学业成绩和生产力，并贯穿其一生。本研究方案将评估由卫生部为巴西改编的 Elos 2.0 计划的有效性，该计划旨在减少 6 至 10 岁儿童的问题行为（例如，多动、攻击性和害羞），并在学校环境中促进社会技能。Elos 计划基于广泛使用的良好行为游戏，通过建立合作条件来预防和/或减少学生的破坏性行为。
将在三个城市的 30 所学校中进行一项群组随机对照试验，共有 3800 名儿童参加测试（对照组 1900 名，干预组 1900 名）。通过让对照组和实验组的教师填写课堂适应教师观察量表（TOCA）来收集数据，这是一种用于观察儿童课堂行为的工具。我们将在同一年的干预前后收集数据。由于数据的层次结构，将进行多级分析，以检测随时间和组别的流行率的同时差异，以控制社会人口变量。
本研究将检验 Elos 2.0 计划在减少问题行为（例如多动、攻击性和害羞）和促进学校环境中的社会技能方面的有效性。这项针对儿童的基于学校的预防计划的发现将通过确定对参与者取得积极成果至关重要的机制，影响为学校和教育政策制定者制定类似计划的发展和实施。
