Association of Type D personality with cognitive functioning in individuals with and without cardiovascular disease: The Gutenberg health study
2016
ObjectiveDistressed (‘Type D’) personality is associated with adverse health outcomes in patients with cardiovascular disease (CVD). While personality traits from the Five-Factor Model are related to cognitive functioning, neither Type D personality nor its underlying traits negative affectivity (NA) and social inhibition (SI) have been investigated regarding cognition. We therefore compared the predictive value of Type D classification and its subcomponents NA and SI on planning performance in individuals with and without CVD.MethodsType D personality traits (DS14) were determined in a population-based sample of 4026 participants (including 549 with CVD) aged 40–80 years from the Gutenberg…
Exposure therapy changes dysfunctional evaluations of somatic symptoms in patients with hypochondriasis (health anxiety). A randomized controlled tri…
2015
Dysfunctional evaluations of somatic symptoms are considered a central factor in maintaining hypochondriasis. The aim of the current study was to investigate whether exposure therapy (ET) without cognitive restructuring is sufficient to change dysfunctional evaluations of somatic symptoms. The current study was based on a randomized controlled trial and compared patients with hypochondriasis (N=73) receiving ET or cognitive therapy (CT) to a wait list (WL) control group. In both the ET and CT groups, dysfunctional symptom evaluations changed significantly compared with the WL group. No differences between the ET and CT groups emerged. The relationship between the treatment condition (active…
rTMS of the prefrontal cortex in the treatment of chronic migraine: a pilot study
2004
A recent fMRI study showed that dorsolateral prefrontal cortex (DLPFC) exerts an inhibitory control on pain pathways in humans. We investigated whether high-frequency rTMS over left DLPFC could ameliorate chronic migraine. Treatment consisted of 12 rTMS sessions, delivered in alternate days over left DLPFC. Sham rTMS was used as placebo. Eleven patients were randomly assigned to the rTMS (n=6) or to the placebo (n=5) treatment. Measures of attack frequency, headache index, number of abortive medications (outcome measures) were recorded in the month before, during and in the month after treatment. Subjects treated by rTMS showed a significant reduction of the outcome measures during and in t…
The catechol-O-methyltransferase Val108/158Met polymorphism affects short-term treatment response to mirtazapine, but not to paroxetine in major depr…
2004
The catechol-O-methyltransferase (COMT) is a major degrading enzyme in the metabolic pathways of catecholaminergic neurotransmitters such as dopamine and norepinephrine. This study investigated whether the functionally relevant Val(108/158)Met gene variant is associated with differential antidepressant response to mirtazapine and/or paroxetine in 102 patients with major depression (DSM-IV criteria) participating in a randomized clinical trial with both drugs. In patients treated with mirtazapine, but not paroxetine, allelic variations in the COMT gene were associated with differential response. COMT(VAL/VAL) and COMT(VAL/MET) genotype carriers showed a better response than COMT(MET/MET)-bea…
Response trajectories in "real-world" naturalistically treated schizophrenia patients.
2011
Abstract Background To date, research has identified distinct antipsychotic response trajectories yet focussing on data from randomized-controlled trials (RCTs). Therefore, the heterogeneity of response in “real-world” schizophrenia patients is still unknown. Methods Antipsychotic response was evaluated in 399 patients suffering from a schizophrenia spectrum disorder within a naturalistic multicenter study of the Competence Network on Schizophrenia using latent class regression. Baseline and illness-related variables were compared between the different trajectory classes as well as currently proposed outcome definitions (early improvement, response, remission) using univariate tests. In ord…
Exploratory Factor Analysis and Validation Study of the Lifetime Severity Index for Cocaine, Spanish Version (LSI-C-Spanish)
2007
The purpose of the study was to do an exploratory factor analysis and to examine the criterion-related and discriminant validity of the Lifetime Severity Index for Cocaine (LSI-C), Spanish version. A sample of 171 outpatients from 10 drug centers in Spain participated in the study. We conducted the factor analysis with orthogonal rotation and examined correlations between the LSI-C total score and criterion variables as well as the score obtained by a quality of life measure. The factor analysis revealed 2 principal factors that explain 65.8% of the variance. Lower LSI-C scores were associated with taking medication, receiving social help, using cocaine fewer than 30 times during the previo…
The effects of social pressure and emotional expression on the cone of gaze in patients with social anxiety disorder
2016
Abstract Background and objectives Patients with social anxiety disorder suffer from pronounced fears in social situations. As gaze perception is crucial in these situations, we examined which factors influence the range of gaze directions where mutual gaze is experienced (the cone of gaze). Methods The social stimulus was modified by changing the number of people (heads) present and the emotional expression of their faces. Participants completed a psychophysical task, in which they had to adjust the eyes of a virtual head to gaze at the edge of the range where mutual eye-contact was experienced. Results The number of heads affected the width of the gaze cone: the more heads, the wider the …
The implicit health-related self-concept in somatoform disorders.
2012
Abstract Background and objective Dual-process theories stress the importance of explicit as well as implicit cognitive processes for the development of somatoform disorders (SFDs). 1 In particular, the self-concept has been demonstrated to be a key factor in SFD. Yet, the self-concept in SFDs has been studied only on an explicit but not on an implicit level. Methods The present study empirically examined the implicit health-related self-concept in SFDs by using the Implicit Association Test (IAT). Twenty-two patients with SFDs (according to DSM-IV) and 27 healthy control participants (CG) completed an IAT to assess associations of the self with illness- versus health-related words. Results…
Cross-national and longitudinal investigation of a short measure of workaholism
2015
The present study investigated the factor structure of the 10-item version of the Dutch Work Addiction Scale (DUWAS). The DUWAS-10 is intended to measure workaholism with two correlated factors: working excessively (WE) and working compulsively (WC). The factor structure of the DUWAS-10 was examined among multi-occupational samples from the Netherlands (n=9,010) and Finland (n=4,567) using confirmatory factor analysis (CFA). CFAs revealed that the expected correlated two-factor solution showed satisfactory fit to the data. However, a second-order factor solution, where WE comprised the first-order factors “working frantically” and “working long hours”, and WC the first-order factors “obsess…
Cross validation of the factor structure of the 20-item Toronto Alexithymia Scale: An Italian multicenter study
1996
The 20-item Toronto Alexithymia Scale (TAS-20) has been shown in previous research to measure a general dimension of alexithymia with three intercorrelated factors. This study evaluated the reliability and factorial validity of an Italian translation of the TAS-20 in a group of normal adults (N = 206) and in a mixed group of medical and psychiatric outpatients (N = 642). Using confirmatory factor analyses, the previously established three-factor model of the TAS-20 was found to be replicable in both groups. In addition, the Italian TAS-20 demonstrated adequate estimates of internal reliability and test-retest reliability. Although evaluation of the convergent, discriminant, and concurrent v…
