Conditions in the Palestinian refugee camps in Lebanon are difficult, with poverty rates high, educational attainment low, and opportunities few. Of concern to policy-makers is ‘Ayn al-Hilweh, the largest camp in Lebanon. This camp experiences frequent factional violence and harbors numerous individuals wanted by Lebanese authorities. This study, using a random survey of households, examined the frequency of households’ experience with violence and the association of experiencing violence with PTSD symptomology. Results show one in five households experienced violence and these experiences were associated with increased PTSD symptomology. Implications for social work within the camp are discussed.
