This paper investigates the experience and dimension of shame as predictors of Posttraumatic Stress Disorder among Liberian refugees in Nigeria. The purpose of the study was to examine total shame, characterological, behavior and body shame on PTSD. The method adopted for this study was a descriptive research design of a survey type. The population was all Liberian refugees living on the refugees’ camp in Ogun State. The sample consisted of 167 Liberian refugees both male and female selected from the camp using purposive random sampling techniques. The Posttraumatic Stress Disorder Checklist with a reliability coefficient of 0.89 and the Experience of Shame scale (ESS) with a reliability coefficient of 0.93 were adapted for this study. The results of the study show that total shame, characterological shame and body shame predicted PTSD while behavior shame failed to PTSD. It was recommended that shame and its dimension be screened among refugees. Those who are high on characterological be invited for compassion mind training in order to enhance other- oriented behavior as means of social competency for proper economic development. And refugees who are high on total shame receive compassion focused therapy to develop self- esteem and the ability to feel inner safeness and self-reassurance to correct erotic thinking. While those who manifest body shame should receive perceptual retraining in order to correct misrepresented body image perception.
