<![CDATA[ABSTRACT The problem of physical aggressive behavior among students remains a concern in the school environment, such as hitting, kicking, pushing, skipping classes, and engaging in fights with peers. This study aimed to determine the effect of behavioral therapy techniques on the physical aggressive behavior of eighth-grade students at SMP Negeri 7 Mataram. This research employed a quantitative approach using a one-group pre-test and post-test design. The population consisted of 207 eighth-grade students, while the sample included 8 students from class VIII B selected through cluster sampling techniques. Data were collected using a physical aggressive behavior questionnaire that had been tested for validity and reliability, consisting of 20 statement items. Data analysis was conducted using the t-test to determine the effect of the treatment provided. The results showed that there was a significant effect of behavioral therapy techniques on students’ physical aggressive behavior. This was evidenced by the t-count value of 5.441, which was higher than the t-table value of 2.365 at a 5% significance level, indicating that H₀ was rejected and Hₐ was accepted. These findings indicate that behavioral therapy techniques are effective in reducing physical aggressive behavior among students at SMP Negeri 7 Mataram in the 2022/2023 academic year.
