Dear Editor, Campbell et al. report an interesting association between nightmares and cardiovascular (CVS) risk [1]. The methodology in this work, however, is limited in ways that must be addressed in future research. In clinical sleep medicine as well as in several sleep research investigations, it is apparent chronic nightmare disorder often co-exists with sleep-disordered breathing (SDB)...
Study objectives: This study aimed to examine psychometric properties of the Disturbing Dream and Nightmare Severity Index (DDNSI) in individuals aged between 18 and 39. Methods: All participants (n = 674) were asked to complete the DDNSI, including the modified Nightmare Effects Survey. Additionally, 109 participants were tested for test-retest reliability after 3 months. Among our sample, 229...
This consensus paper provides an overview of the state of the art in research on the aetiology and treatment of nightmare disorder and outlines further perspectives on these issues. It presents a definition of nightmares and nightmare disorder followed by epidemiological findings, and then explains existing models of nightmare aetiology in traumatized and non-traumatized individuals. Chronic...
Objective At-risk high school students, those considered to have a higher probability for academic failure or dropping out, were assessed for various sleep disorders. Effects were compared between students with and without the nightmare triad syndrome (NTS+), the sleep disorders' cluster of frequent nightmares, insomnia disorder and suspected sleep-disordered breathing (SDB). Methods Data were...
Sleep medicine specialists view the problem of chronic nightmare disorder as an independent sleep disorder. When patients seek treatment for chronic nightmares, a direct intervention may be offered regardless of the putative causes. This approach derives from the assumption that nightmares may persist because they “take on a life of their own” (Krakow & Zadra, 2006a) despite the fact that...
Nightmares are a universal and timeless phenomenon. They occur in most healthy adults as well as a significant portion of clinical populations, especially those exposed to trauma. Considerable advances in the pharmacological and psychological treatment of post-traumatic nightmares have occurred over the last decade with continuing advances in psychological interventions over the last few years....
The aim of this review is to evaluate the effectiveness of cognitive behavioral therapy (CBT) on nightmare frequency and to determine which kind of CBT is the most effective treatment. A systematic literature search was carried out in PsychInfo and PubMed articles published on or before May 1, 2008. The inclusion criteria were: nightmare treatment study, use of nonpharmacological treatment, not...
Problems with nightmares are reported by a sizable proportion of individuals with a history of trauma and by approximately 5% to 8% of the general population. Chronic nightmares may represent a primary sleep disorder rather than a symptom of a psychiatric disorder, and direct targeting of nightmares is a feasible clinical approach to the problem. Of the treatments proposed, imagery rehearsal...
Exposure, abreaction, and mastery have been proposed as the therapeutic processes of nightmare (NM) reduction. Imagery rehearsal therapy (IRT) effectively reduces NMs but involves minimal exposure and abreaction. The authors investigated the use of mastery in the scripting of new dreams (NDs) elaborated during IRT. NM an dN D reports were collected from 44 female sexual assault survivors with...
To evaluate imagery rehearsal therapy for the treatment of chronic nightmares in a sample of adolescent girls. Adolescent girls ranging in age from 13 to 18 years were recruited from the Wyoming Girls School in Sheridan, Wyoming (treatment group, n = 9; control group, n = 10). These girls had previously suffered a high prevalence of unwanted sexual experiences in childhood and adolescence, and...
Chronic nightmares occur frequently in patients with posttraumatic stress disorder (PTSD) but are not usually a primary target of treatment. To determine if treating chronic nightmares with imagery rehearsal therapy (IRT) reduces the frequency of disturbing dreams, improves sleep quality, and decreases PTSD symptom severity. Randomized controlled trial conducted from 1995 to 1999 among 168...
Imagery-rehearsal therapy for chronic nightmares was assessed in a randomized, controlled study of sexual assault survivors with posttraumatic stress disorder (PTSD). Nightmares, sleep quality, and PTSD were assessed at baseline for 169 women, who were randomized into two groups: treatment (n = 87) and wait-list control (n = 82). Treatment consisted of two 3-hr sessions and one 1-hr session...
An eighteen month follow-up of chronic nightmare sufferers treated with imagery rehearsal, a cognitive-behavioral method, demonstrated significant and clinically meaningful decreases in nightmare frequency. Sixty-eight percent of subjects decreased their nightmares below criteria for a “Chronic Nightmare Disorder”. Significant improvement was also noted for sleep quality and daytime anxiety....
Nightmare frequency and self-rated distress were assessed retrospectively in two groups of chronic nightmare sufferers 30 months after treatment. In the initial phase, the image group (N = 9) learned a cognitive-behavioral technique (imagery rehearsal) for the treatment of nightmares. They were taught in one group session to: (1) record a nightmare; (2) change it (usually to something...
