Initial psychometric properties of the SLEEP-50 questionnaire, designed to detect sleep disorders as listed in the Diagnostic and Statistical Manual of Mental Disorders (4th ed., Text Revision), were examined. The sample consisted of 377 college students, 246 sleep patients, 32 nightmare sufferers, and 44 healthy volunteers. The internal consistency was(More)
Posttraumatic Stress Disorder (PTSD) is defined in DSM-IV as an anxiety disorder that encompasses symptom-clusters of reexperiencing, avoidance, and hyperarousal. Several studies have examined the factor structure of PTSD symptoms. To our knowledge, no studies have yet examined the factor structure of loss-related PTSD symptoms in samples exclusively(More)
Ruminative coping has been associated with negative outcomes in bereavement. Rather than assuming it to be a problematic confrontation process, researchers have recently suggested rumination to be maladaptive through its links with avoidance processes. The main aim of this study was to examine, for the first time, whether the relationship between ruminative(More)
The DSM-IV-TR definition of nightmares-extremely frightening dreams from which the person wakes up directly-is unnecessarily narrow. Other emotions (anger, grief) have also been reported in nightmares, and direct awakening from a bad dream seems to be unrelated to increased distress. In addition, assessment of nightmares is problematic. Polysomnographic(More)

Four-hundred-and-two randomly approached adults received three questionnaires. Results showed a high interrelatedness between sleep and depressive/anxiety complaints.

In this study the temporal stability and general discriminative and classifying ability of the Young Schema-Questionnaire (YSQ) was examined in a clinical and non-clinical sample. To be able to cross-validate on the variables, two parallel subtests, drawn from the YSQ item pool, were utilized. Results suggest adequate rank order stability. However, mean(More)
Research so far has shown little evidence that written disclosure facilitates recovery from bereavement. There are good reasons to assume that written disclosure may only benefit those bereaved who are at risk for developing problems or who are experiencing significant psychological problems as a result of their loss, and only when appropriate writing(More)
Internet-delivered treatment is effective for insomnia, but little is known about the beneficial effects of support. The aim of the current study was to investigate the additional effects of low-intensity support to an internet-delivered treatment for insomnia. Two hundred and sixty-two participants were randomized to an internet-delivered intervention for(More)
Cognitive behavioural conceptualisations of grief propose that negative cognitions and avoidance strategies play a key role in emotional problems after bereavement. In the current study, this assumption was examined. Ninety-seven individuals who had lost a relative less than 5 months ago completed questionnaires tapping background and loss-related(More)
The present study sought to explore the relationship between negative cognitions and emotional problems after bereavement, with a group of 329 adults who had suffered the loss of a first degree relative. The following cognitions were assessed: global negative beliefs, cognitions about self-blame, negative cognitions about other people's responses after the(More)
