The study examined the level of secondary traumatization among adult children of Israeli war veterans with post-traumatic stress disorder (PTSD) as manifested in emotional distress, stress resulting from terrorist attacks, and capacity for intimacy. In addition, the role of the mother-child relationship as a moderator of these manifestations of distress was examined. Forty-six adult children of fathers with chronic PTSD, and 46 adult children of fathers who had participated in a war but did not have PTSD participated. Findings revealed that adult children of PTSD veterans showed higher levels of psychological distress, greater terror-related stress, and a lower capacity for intimacy than children of non-PTSD veterans. Positive relationship with the mother was found to moderate the level of participants' capacity for intimacy and their levels of psychiatric symptoms. (Contains 2 tables.)
