ABSTRACT
Cognitive-behavioral treatments (CBTs) that target nightmares are efficacious for ameliorating self-reported sleep problems and psychological distress. However, it is important to determine whether these treatments influence objective markers of nightmare-related fear, because fear and concomitant physiological responses could promote nightmare chronicity and sleep disturbance. This randomized, controlled study (N=40) assessed physiological (skin conductance, heart rate, facial electromyogram) and subjective (displeasure, fear, anger, sadness, arousal) reactions to personally relevant nightmare imagery intended to evoke nightmare-related fear. Physiological assessments were conducted at pretreatment as well as 1-week, 3-months, and 6-months posttreatment. Results of mixed effects analysis of variance models suggested treatment reduced physiological and subjective reactions to nightmare imagery, gains that were generally maintained at the 6-month follow-up. Potential implications are discussed.

Research findings have been equivocal regarding the relationship between experiencing trauma and exhibiting violent behavior in women. This study seeks to determine predictors of violent behavior in female inmates utilizing various conceptualizations of traumatic experiences. Results indicate a significant univariate relationship between experiencing more frequent physical abuse experiences, both interpersonal and noninterpersonal types of trauma, and both physical and sexual assaults with frequency of engagement in violent behavior. The regression model explained approximately 21.0% of the variance in violent behavior. Furthermore, frequency of physical abuse experiences was a significant predictor of frequency of engagement in violent behavior and explained 12.74% of unique variance. These results suggest that the frequency of physical abuse experiences may serve as a risk factor for women's violent behavior. Although more research is needed, it appears that addressing the potential for violence in women who experience abuse may be an appropriate target of treatment.

Script-driven imagery was used to assess nightmare imagery-evoked physiological-emotional reactivity (heart rate, skin conductance, facial electromyogram, subjective ratings) in trauma-exposed persons suffering from chronic nightmares. Goals were to determine the efficacy of nightmare imagery to evoke physiological-emotional reactivity, correlates (mental health, nightmare characteristics) of reactivity, and consequences (sleep and health problems) of reactivity. Nightmare imagery resulted in significant reactivity relative to control imagery. No mental health variable (posttraumatic stress disorder status, depressive symptoms, dissociation) or nightmare characteristic (months experienced, frequency, similarity to trauma) was associated with reactivity level. However, nightmare imagery-evoked autonomic responses were associated with greater sleep disturbance and reported health symptoms, even when nightmare frequency was controlled. These results suggest nightmare-related autonomic reactions may contribute to sleep and health disturbance.
