Stress symptoms one year after 9/11/01: a follow-up

This study investigated whether stress symptoms related to attention deficit previously found for a sample (n= 149) of Chicago-area college students 1 to 5 weeks after the September 11th attacks were present in a comparable sample (n = 129) 12 to 14 months later. As hypothesized, the later participants had a significantly lower mean score on the scale, Attention Deficit of the Smith Stress Symptoms Inventory, than a different group of participants tested immediately after the attacks. Mean Attention Deficit scores for groups after one year and immediately before September 11th (n=320) did not differ statistically. Findings are consistent with the interpretation that elevations in scores on Attention Deficit immediately after September 11th were indeed associated with the catastrophic attacks and not artifacts of time of examination. Consistent with previous research with this inventory, disaster-related traumatic stress scores are lower over time, although here no control group was included.
