Description:
Although previous work has found associations between panic and smoking, little research has investigated potential mechanisms by which smoking may contribute to panic problems. The present investigation evaluated the incremental validity of acute nicotine withdrawal symptoms (elicited by an average of 2h of nicotine deprivation) relative to negative affectivity, anxiety sensitivity, and nicotine dependence in predicting anxiety responding to 3-min voluntary hyperventilation. The sample consisted of 90 regular smokers (46 females), as defined by smoking >=10 cigarettes per day for at least 1 year, recruited through the general community. Consistent with prediction, greater levels of pre-challenge nicotine withdrawal symptoms uniquely predicted post-challenge intensity of panic symptoms and anxiety relative to other established factors. Findings are discussed in the context of how regular smoking may promote panic symptomotology.

Description:
Papers in this special issue of the Journal of Anxiety Disorders concern critical issues and core assumptions that underlie the diagnostic construct of posttraumatic stress disorder. Rather than addressing specific points raised in these papers, we consider the issues and their implications for redefining PTSD and associated disorders in the DSM-V. Specific proposals are advanced to tighten definitional criteria for traumatic events and posttraumatic symptoms. We believe the more stringent criteria express the intent of the PTSD category and will promote more effective research on whether that intent was legitimate or based on misconceptions.

Description:
This study investigated the relationship of hyperarousal and intrusive symptoms in acute stress disorder (ASD). Civilian trauma survivors with ASD (n = 18) and without ASD (n = 14) completed a hyperventilation provocation test (HVPT) and then completed the Physical Reactions Scale. All participants provided a narrative describing their hyperventilation experience that was audiotaped and independently coded. Individuals with ASD reported greater numbers of intrusive memories and reported greater distress than non-ASD participants. More ASD than non-ASD participants experienced a flashback-type reaction during the hyperventilation. Intrusive symptoms were significantly correlated with elevated arousal following the HVPT. The findings provide evidence that reexperiencing is directly associated with elevated states of arousal.
