Mount Merapi eruption in 2010 is categorized as the largest eruption during the last 20 years. The effect of the eruption caused not only many casualties, environmental damage, but also deep trauma to the residents living on the slopes of the mountain, especially the teenagers. The design of the applied experiment was a pre-test post-test control group design. It is a design of experiment involving two group i.e. experimental and control in which the target behaviour of the subjects is measured before and after the experimental treatment given. The result of t-test analysis namely independent sample t-test in the experimental and control group using gain score indicates that there is different mean between the experimental group and the control group. The result of t-test analysis shows t = 1.925 and p = 0.059 (sig. 2-tailed), 0.0295 (sig 1-tailed) (p <0.05). Therefore, it is significant. It means there is a significant difference in Post-Traumatic Stress Disorder (PTSD) between the experimental group and the control one. The experimental group has a lower rate of PTSD compared with the control group. It can be concluded that trauma healing methods are effective to reduce PTSD.
