Predictors of Peritraumatic Reactions and PTSD Following the September 11th Terrorist Attacks

In this study the authors characterize peritraumatic reactions of residents of New York City during and immediately following the September 11th terrorist attacks, identify predictors of those reactions, and identify predictors of PTSD 4 months later. A cross–sectional sample of New York residents (n = 2,001) responded to questions about sociodemographics, historical factors, event–related exposure; acute cognitive, emotional, and physiological reactions to the September 11th terrorist attacks; and current (past month) PTSD symptoms. Factor analyses of peritraumatic reactions yielded three related, but distinct, peritraumatic response patterns—dissociation, emotional reactions, and panic/physiological arousal. Several demographic, historical, and exposure–related variables predicted one or more peritraumatic reaction patterns. After controlling for demographic, historical, and exposure factors, each of the peritraumatic reactions factors, one historical factor and one event–related exposure factor remained as significant predictors of PTSD. These results support a growing literature concerning the predictive value of peritraumatic reactions in relation to PTSD. Implications for preventive efforts and suggestions for future research are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/40315/2/Lawyer_Predictors of peritraumatic reactions and PTSD_2006.pd

Heavy drinking among college students is influenced by anxiety sensitivity, gender, and contexts for alcohol use

In order to quantify relationships between anxiety sensitivity and situational antecedents to heavy alcohol consumption, 245 university student drinkers completed the anxiety sensitivity index-revised (ASI-R) and the inventory of drinking situations (IDS-42). The observed correlations indicated that anxiety sensitivity is related to negatively reinforced drinking, positively reinforced drinking, and temptation-motivated drinking. However, anxiety sensitivity is most clearly implicated as a factor in negatively reinforced drinking, i.e., drinking followed by \u27tension reduction.\u27 Additionally, the relationship between anxiety sensitivity and negatively reinforced drinking is stronger among males than among females. The results point to anxiety sensitivity and gender as interacting individual difference variables that influence incidence of negatively reinforced heavy drinking among college students. © 2002 Elsevier Science Inc
