One of the most challenging issues in public health is preventing aggression and violent behavior, generally in the adolescent population. Intervention studies in this field, especially in Iran, were few. Moreover, their findings are controversial. Therefore, this study was conducted to investigate the effect of educational intervention based on the theory of planned behavior (TPB) on reducing aggression among male students.
This study used a randomized controlled trial design. The sample comprised 98 middle school students aged between 13 and 16 years (14.28 ± 0.7). Educational intervention for the experimental group consisted of five sessions of 45-60 minutes. Data were collected using two self-administered questionnaires to measure aggression and constructs of TPB. Data were analyzed using paired -test, independent -test, and chi-square test at a significance level of 0.05.
After the intervention, the experimental group showed a significant increase in all TPB constructs except the subjective norms, compared to the control group ( < 0.001). After two months of intervention, the mean score of the aggression behaviors in students in the experimental group showed a remarkable improvement in the experimental group, while the control group showed no significant difference.
The findings of this study showed that the theory-based educational intervention was effective on the improvement of aggressive behavior. To achieve a significant change in perceived mental norms, more training sessions are recommended, and emphasis is placed on educating parents, peers, and school staff.
公共卫生领域最具挑战性的问题之一是预防攻击和暴力行为，尤其是在青少年群体中。该领域的干预研究在伊朗很少见。此外，他们的发现存在争议。因此，本研究旨在调查基于计划行为理论（TPB）的教育干预对减少男学生攻击行为的影响。
本研究采用随机对照试验设计。样本包括 98 名年龄在 13 至 16 岁之间（14.28±0.7）的中学生。实验组的教育干预包括五节 45-60 分钟的课程。使用两份自我管理问卷收集数据，以测量攻击行为和 TPB 结构。数据采用配对 t 检验、独立 t 检验和卡方检验进行分析，显著性水平为 0.05。
干预后，实验组除主观规范外，所有 TPB 结构均显著增加，与对照组相比（<0.001）。干预两个月后，实验组学生的攻击行为平均得分显著改善，而对照组则无显著差异。
本研究结果表明，基于理论的教育干预对改善攻击行为有效。为了显著改变感知心理规范，建议增加更多的培训课程，并强调对家长、同伴和学校工作人员进行教育。
