<![CDATA[This study examined the effect of an information service delivered through Powtoon animation on students' anti-verbal-violence attitudes at SMA Negeri 1 Percut Sei Tuan. A quantitative quasi-experimental approach with a pretest-posttest control group design was used. Seventy students from two intact classes participated, with 35 students in the experimental group and 35 in the control group. Total sampling was used. Data were collected using a Likert-type questionnaire measuring anti-verbal-violence attitudes that had undergone validity and reliability testing. Normality was assessed using the Shapiro-Wilk test, within-group changes were examined using paired-samples t tests, and intervention effectiveness was evaluated by comparing gain scores between groups using an independent-samples t test. The experimental group's mean increased from 99.11 to 117.03, while the control group's mean increased from 106.29 to 119.37. The paired-samples tests were significant in both groups (p < .001). Importantly, the experimental gain (M = 17.91, SD = 6.84) was significantly greater than the control gain (M = 13.09, SD = 6.61), t(68) = 3.002, p = .004, Cohen's d = 0.72. The findings indicate that Powtoon-based information services provide an added benefit in strengthening anti-verbal-violence attitudes. The study supports the use of animation as a preventive medium in school guidance and counseling, while emphasizing the need for sustained, whole-school prevention efforts.]]>
