Stress-induced cortisol elevations are associated with impaired delayed, but not immediate recall.

Psychiatry Res

April 2005

Section of Clinical and Health Psychology, University of Leiden, P.O. Box 9555, 2300 RB Leiden, The Netherlands.

Glucocorticoids are known to modulate memory functions, with elevated cortisol levels being associated with impaired declarative memory. This specific effect has been shown in several studies using pharmacological doses of cortisol. The present study was designed to assess the effects of stress-induced cortisol elevations on (1) the type of memory processing (encoding, consolidation and retrieval), and (2) on the emotional valence of the material under study.

The effects of stress-induced cortisol responses on approach-avoidance behavior.

Psychoneuroendocrinology

August 2005

Section of Clinical and Health Psychology, University of Leiden, P.O. Box 9555, 2300 RB Leiden, The Netherlands.

High glucocorticoid stress-responses are associated with prolonged freezing reactions and decreased active approach and avoidance behavior in animals. The present study was designed to investigate the effects of cortisol responses and trait avoidance on approach-avoidance behavior in humans. Twenty individuals were administered a computerized approach-avoidance (AA)-task before and after stress-induction (Trier Social Stress Test).

Trauma and dissociation in conversion disorder and chronic pelvic pain.

Int J Psychiatry Med

July 2005

Faculty of Social and Behavioral Sciences, Section of Clinical and Health Psychology, Leiden University, The Netherlands.

Objective: The purpose of this study was to: a) assess the link between sexual and/or physical abuse and dissociation in conversion disorder and chronic pelvic pain patients; and b) assess whether this effect is independent of level of general psychopathology.

Method: This report examines data from four separate samples. Fifty-two patients with chronic pelvic pain, 61 patients with non-epileptic seizures, and two samples of patients (102 and 54) with predominantly motor or sensory types of conversion disorder were studied.

Cortisol-induced impairments of working memory require acute sympathetic activation.

Behav Neurosci

February 2005

Section of Clinical and Health Psychology, University of Leiden, Leiden, Netherlands.

The present study assessed whether the effects of cortisol on working memory depend on the level of adrenergic activity (as measured by sympathetic activation) during memory performance. After exposure to a psychosocial stress task, participants were divided into cortisol responders and nonresponders. Cortisol responders showed working memory impairments during the psychosocial stress phase, when cortisol and adrenergic activity were enhanced, whereas nonresponders did not.

The criterion validity of the Center for Epidemiological Studies Depression Scale (CES-D) in a sample of self-referred elders with depressive symptomatology.

Int J Geriatr Psychiatry

June 2004

Section of Clinical and Health Psychology, Faculty of Social and Behavioral Sciences, Leiden University, Leiden, The Netherlands.

Background: The criterion validity of the Center for Epidemiological Studies Depression scale (CES-D) was assessed in a group of elderly Dutch community-residents who were self-referred to a prevention program for depression.

Methods: Paper-and-pencil administration of the CES-D to 318 elders (55-85 years). Criterion validity was evaluated with the Mini International Neuropsychiatric Interview (MINI), a clinical diagnostic interview based on DSM-IV.

Personality and affect as determinants of medically unexplained symptoms in primary care; A follow-up study.

J Psychosom Res

March 2004

Section of Clinical and Health Psychology (KLIG), Department Psychology, Faculty of Social Sciences, Leiden University, Pieter de la Court Building, Wassenaarseweg 52, PO Box 9555, 2300 RB Leiden, The Netherlands.

Objective: To examine whether the personality dimensions, neuroticism and alexithymia, and the affective state dimensions measuring negative and positive affect significantly contributed to changes over time in the number of medically unexplained symptoms (MUS) reported.

Methods: A total of 318 patients, presenting to their primary care physician with MUS, participated in the study. Logistic regression analyses were conducted to assess to what extent neuroticism, alexithymia, negative affect and positive affect independently contributed to (1) increase vs.

The effects of failing to control pain: an experimental investigation.

Pain

February 2004

Section of Clinical and Health Psychology and Department of Psychiatry, University of Leiden, P.O. Box 9555, 2300 RB Leiden, The Netherlands Department of Medical, Clinical and Experimental Psychology, Maastricht University, Maastricht, The Netherlands.

Chronic pain patients are often confronted with repeated failure to achieve pain relief. The aim of this study was to experimentally investigate the effects of repeated failing attempts to control pain on pain impact (pain intensity, emotional and physiological responses). Perceived control over an electrocutaneous pain stimulus was manipulated between subjects by success or failure feedback on a task by which control over pain could be acquired.

Anxiety and depression after spontaneous subarachnoid hemorrhage.

Neurosurgery

January 2004

Section of Clinical and Health Psychology, University of Edinburgh, Edinburgh, Scotland.

Objective: Relatively little attention has been paid to emotional outcome after subarachnoid hemorrhage (SAH). This study assessed levels of anxiety and depression among SAH survivors and related these to clinical indices.

Methods: Seventy SAH patients from a consecutive series of neurosurgical admissions participated in semistructured assessments of functional outcome; 52 of the patients also returned standardized measures of emotional outcome.

Stability of neuroticism and alexithymia in somatization.

Compr Psychiatry

April 2004

Department of Psychology, Section of Clinical and Health Psychology, Leiden University, Leiden, The Netherlands.

The personality traits neuroticism and alexithymia have been hypothesized as predisposing factors for somatization. Stability over time is a basic assumption underlying any trait construct. Although there are considerable (and sometimes conflicting) data relevant to this issue, the stability of neuroticism and alexithymia has not been assessed in somatization.

Animal studies have found that prior stressful events can result in increased reactivity in the HPA-axis. However, baseline function of the HPA-axis has typically been normal or decreased in post-traumatic stress disorder (PTSD). The first purpose of this study was to assess cortisol responsivity to traumatic reminders in women with PTSD related to childhood abuse.

To investigate amnesia between identities in dissociative identity disorder (DID), the authors assessed explicit and implicit memory performance on a directed-forgetting task in 12 DID patients who switched from one state to an "amnesic" state between presentation and memory testing. DID patients were instructed either to remember or to forget neutral and emotional words. Besides an overall decrease in explicit memory, patients demonstrated selective forgetting of to-be-forgotten, but not of to-be-remembered words in the amnesic state.

Restricted emotional processing and somatic attribution in fibromyalgia.

Int J Psychiatry Med

April 2002

Section of Clinical and Health Psychology, University of Leiden, The Netherlands.

Objective: Medically unexplained symptoms or syndromes, such as fibromyalgia (FM), might be partly caused or sustained by a mechanism involving restricted emotional processing (REP) and the subsequent attribution of emotional arousal to somatic or syndrome-consistent causes. In this study, it was hypothesized that FM patients, compared to healthy individuals, would be higher on trait measures of REP (defensiveness and alexithymia), and would show affective-autonomic response dissociation, that is, higher standardized scores of heart rate responses than affective responses, during negative emotional stimulation. Additionally, FM patients were expected to attribute their bodily symptoms more to somatic than to psychological causes.
