An experimental analysis of chronic posttraumatic stress among adolescents.

Abstract

The Fear Survey Schedule (FSS), State Trait Anxiety Inventory (STAI), and the Lebanese Fear Inventory (FLI, an endemic index of war fears) were administered to a sample of Lebanese junior high school students 27 days before the Israeli invasion of 1982. Six months after the disengagement of forces, the investigator located 16 subjects who had been in West Beirut throughout the siege and 46 subjects who had evacuated to safer environs. The inventories were readministered to the subjects according to a counterbalanced regimen and no significant differences were noted between the preinvasion scores of the evacuees and nonevacuees or between the postinvasion scores of the evacuees and nonevacuees. No significant differences were observed when the aggregate FSS and STAI estimates that were recorded before and after the invasion were compared. On the other hand, the aggregate LFI scores were significantly lower after the invasion. The results are discussed from within the social learning framework of fear acquisition.
