BACKGROUND Several reports suggest beneficial impacts of either physical or mental activity on cognitive function in old age.

METHODS This randomized controlled trial evaluates a cognitive and a physical standardized(More)
The predictive value of a comprehensive model with personality characteristics, stressor related cognitions, coping and social support was tested in a sample of 187 nonpregnant women. The emotional response to the unsuccessful treatment was predicted out of vulnerability factors assessed before the start of the treatment. The results indicated the(More)
Patients' expectations are important predictors of the outcome of analgesic treatments, as demonstrated predominantly in research on placebo effects. Three commonly investigated interventions that have been found to induce expectations (verbal suggestion, conditioning, and mental imagery) entail promising, brief, and easy-to-implement adjunctive procedures(More)
This article presents a series of studies aimed at validating a comprehensive pain-coping inventory (PCI) that is applicable to various types of patients with chronic pain. Item and scale analyses were performed for patients with rheumatoid arthritis (RA), patients with chronic headache, and pain clinic outpatients. The following 6 scales were derived from(More)
Itch is a major feature of many skin diseases, which adversely affects patient's quality of life. Besides disease severity, psychophysiological factors have been proposed to influence the itch sensation. In this review the evidence for a biopsychosocial model of itch is described, focusing in particular on evidence for the effects of personality(More)
Patients frequently report high levels of physical symptoms, such as itch and pain, which do not completely correspond to pathophysiological findings, possibly indication heightened sensitivity to physical symptoms. Sensitivity to itch and pain is thought to be affected by processes such as attentional focus on bodily sensations. We investigated the role of(More)
Pain can be endogenously modulated by heterotopic noxious conditioning stimulation (HNCS) through a mechanism which is known as diffuse noxious inhibitory control (DNIC). Since DNIC can be impaired in patients suffering from chronic pain, a comparable impaired itch inhibition may exist in patients suffering from chronic itch. The aim of the present study(More)
BACKGROUND Stress management interventions may prove useful in preventing the detrimental effects of stress on health. This study assessed the effects of a stress management intervention on the psychophysiological response to stress in patients with rheumatoid arthritis (RA). METHODS Seventy-four patients with RA, who were randomly assigned to either a(More)
Sensitive skin is a frequent complaint in the general population, in patients, and among subjects suffering from itch. The International Forum for the Study of Itch (IFSI) decided to initiate a special interest group (SIG) on sensitive skin. Using the Delphi method, sensitive skin was defined as "A syndrome defined by the occurrence of unpleasant sensations(More)
