War-induced psychic trauma: an 18-year follow-up of Israeli veterans.

Eighteen years after their participation in the Yom Kippur War, the psychiatric status of two groups of Israeli veterans--112 combat stress reaction casualties and 189 comparable controls--was assessed. Casualties had higher rates and greater intensity of posttraumatic stress disorder than did controls, both initially and at 18-year follow-up. Similarly, intrusion and avoidance tendencies and psychiatric symptomatology were evidenced more often by combat stress reaction casualties than by controls. Clinical implications of the findings are discussed.
