What this trial studies

This study evaluates the effectiveness of the Motivated Social Emotional Learning (MSEL) program compared to traditional Curriculum-based Social Emotional Learning (CSEL) in reducing bullying behaviors among primary school students in Hong Kong. The intervention focuses on enhancing students' autonomy, competence, and relatedness through tailored social-emotional learning activities. It aims to empower students to take on responsible roles and engage in prosocial behaviors, thereby reducing both bullying perpetration and victimization. The study will assess outcomes at posttest and a 3-month follow-up to determine the lasting impact of the interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are primary school students aged 9-13 years from public schools in Hong Kong that fall within the middle band of academic ratings.

Not a fit: Students from single-sex schools or those enrolled in other anti-bullying programs may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could significantly reduce bullying incidents and improve the social-emotional well-being of primary school students.

How similar studies have performed: Previous studies have shown that social-emotional learning programs can effectively reduce bullying, suggesting that this approach may yield positive results.

Eligibility criteria

Show full inclusion / exclusion criteria
* The inclusion criteria for schools, classes, and students are as follows.

  1. Primary School: To reduce the confounding effect of academic achievements on student behavior, only public schools in the middle band (i.e., the middle 33% of academic ratings) in Hong Kong will be included in the sampling. Single-sex schools will be excluded in consideration of the sampling diversity. Furthermore, schools implementing other manualized anti-bullying programs will not be included.
  2. Classes: The inclusion criteria are classes from Grade 4 and 6 (ages 9-13 years old). This research specifically targets classes in Grades 4 and 6 for several reasons. First, studying the integration of adaptive and maladaptive functions of problematic behaviors during this sensitive period may have a greater impact on young adolescents (Ellis et al., 2011). Secondly, a meta-analysis conducted by Yeager et al. (2015) reveals that the effectiveness of anti-bullying interventions declines significantly after Grade 7. Hence, the trial focuses on classes in Grades 4-6.
  3. Students: Inclusion criteria for students specify that they must be enrolled in the class and regularly attend its lessons.
* The exclusion criteria schools executing other manualized anti-bullying programs are excluded in this intervention.
