Brain density in depression: methodological and psychopathological aspects

1988

The relationship between brain density, measured by computerized tomography (CT), and severity of depression was investigated in 44 patients with a major depressive episode according to DSM-III. In order to limit methodological problems, correlations between both the Brief Psychiatric Rating Scale (BPRS) and the Bech-Rafaelsen Melancholia Scale (BRMS) with density values were controlled for age, different ventricle measurements, brain size, and density and size of the skull. The BRMS score correlated inversely with density of the right thalamus, the right head of the caudate, and with parietal grey matter and occipital regions of both hemispheres. Similar, but nonsignificant results, were o…

A polydiagnostic scale for dimensional classification of endogenous depression. Derivation and validation.

1986

Several operational diagnoses (OPD) for endogenous depression have been proposed. However--though aiming at similar clinical concepts--the amount of association and agreement between different OPD is rather low. In this study the relationship between eight OPD (Research Diagnostic Criteria, DSM-III, Michigan Discrimination Index, Newcastle Scale I, Newcastle Scale II, Taylor-Abrams Criteria, Vienna Research Criteria, Hamilton Endogenomorphy Index) was assessed by applying latent trait analyses to the classificatory data of these eight OPD which were rated simultaneously in a sample of 173 depressive inpatients. According to these analyses six OPD (RDC, DSM-III, NCS-I, NCS-II, TAC and VRC) a…

Liebowitz Social Anxiety Scale (LSAS): Optimal cut points for remission and response in a German sample

2017

The Liebowitz Social Anxiety Scale (LSAS) is the most frequently used instrument to assess social anxiety disorder (SAD) in clinical research and practice. Both a self-reported (LSAS-SR) and a clinician-administered (LSAS-CA) version are available. The aim of the present study was to define optimal cut-off (OC) scores for remission and response to treatment for the LSAS in a German sample. Data of N = 311 patients with SAD were used who had completed psychotherapeutic treatment within a multicentre randomized controlled trial. Diagnosis of SAD and reduction in symptom severity according to the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th editi…

Psychometric properties of the General Self Efficacy-12 Scale in Spanish: general and clinical population samples.

2014

The General Self Efficacy Scale (GSES-12) is a short version of the Sherer’s Self-Efficacy Scale, and evaluates a general dimension and three aspects of self-efficacy: initiative, persistence and effort. The aim of this study is to explore the factorial structure, reliability, and criterion validity of the Spanish adaptation of the GSES-12 in general and clinical populations. The sample was composed of 714 volunteers (332 from the clinical population). Results of the principal components analysis yielded a 3-factor structure that was later confirmed through Confirmatory Factor Analysis. Moreover, this study shows good internal consistency and testretest values, and differences in self-effic…

Rasch scalability of the somatosensory amplification scale: a mixture distribution approach.

2012

Abstract Objective Somatosensory amplification refers to a person's tendency to experience somatic sensations as inappropriately intense and involves hypervigilance concerning bodily sensations. We applied the Somatosensory Amplification Scale (SSAS) in an Internet sample of young adults (N = 3031) to test whether the SSAS is Rasch scalable. Methods We applied mixture distribution extensions of the partial credit and rating scale models to identify possible subgroups that use the response set of the SSAS in different ways. Results A partial credit model, with two latent classes, showed a superior fit to all other models. Still, one of the SSAS items had to be removed because it showed sever…

Development of a new measure for assessing insight: Psychometric properties of the insight orientation scale (IOS)

2015

Abstract Introduction Given the centrality of insight in promoting change, the relevance of measures for assessing this construct has become increasingly clear. This paper describes a new self-report measure for assessing some of the characteristics of insight, the insight orientation scale (IOS). Aims In study 1, we evaluated the factor structure and the reliability of the scale. In study 2, we analyzed the concurrent and discriminant validity of the scale in patients with different clinical diagnoses. Methods In study 1 participants were 600 individuals (41.1% male, 58.9% female) with a mean age of 33.95 years (SD = 13.04). In study 2 participants were 136 individuals divided into the fol…

Predictors of neurocognitive impairment at 3years after a first episode non-affective psychosis

2013

Abstract Background Neurocognitive impairment is a core component of schizophrenia. However, patients show great variability in the level and course of deficits. The goal of the present longitudinal study was to identify predictors of neurocognitive impairment in first episode psychosis patients. Methods N eurocognitive performance was analyzed in a cohort of 146 patients 3 years after a first episode non-affective psychosis. Subgroups, impaired vs. unimpaired, were compared on baseline clinical, neuropsychological, premorbid and sociodemographic characteristics. Results Fifty-nine percent of participants presented general neurocognitive impairment and regression analyses demonstrated that …
