Characteristics of Chronic Nightmares in a Trauma-Exposed Treatment-Seeking Sample

Chronic nightmares pose a significant problem for many individuals affected by trauma. The present study attempts to extend current knowledge on the nature, characteristics, and associated sequelae of chronic nightmares. Data were collected from 94 trauma-exposed, treatment-seeking participants (74 women and 20 men). These data suggest that most participants reported their nightmares to be similar or dissimilar to their traumatic experience rather than exact replications (replicative). Not surprisingly, though, nightmarerelated distress was positively related to the degree of similarity between their nightmare and their trauma, with replicative nightmares eliciting the greatest distress. Persons with a current diagnosis of posttraumatic stress disorder (PTSD) were more likely to report problems related to nightmares and sleep disturbance than persons without current PTSD. Nonetheless, even after controlling for PTSD-related symptomatology, frequency and severity of nightmares significantly predicted some distress outcomes (e.g., poor sleep quality), suggesting that nightmares contribute to psychological distress above and beyond PTSD symptoms. Implications for future research, and for the treatment of nightmares and PTSD, are discussed.
