Differences between boys' and girls' exposure to terror and posttraumatic symptoms were examined in a sample of 2,999 Israeli adolescents. Gender differences were also assessed regarding perceived social support, religious beliefs, and ideological commitment. Results indicate that girls reported more posttraumatic symptoms than boys, although boys reported twice the rate of very severe symptoms. Differences were also found between boys and girls in levels of fear, religiosity, ideological commitment, and social support, but not regarding exposure. Path analysis revealed that gender is not a direct predictor of posttraumatic stress disorder (PTSD); however, it does have an indirect effect, especially through fear, which was the best predictor of PTSD. Social extrinsic religiosity and ideological intolerance were positive predictors of PTSD. The study concludes that gender differences in PTSD are largely the result of differences in levels of fear and are not due to differences in political ideology, religiosity, or social support.
