Measuring stress in clinical and nonclinical subjects using a German adaptation of the Perceived Stress Scale

2020

ANTECEDENTES/OBJETIVO: El estrés se percibe de manera diferente entre los individuos, lo que podría ser particularmente cierto para los sujetos no clínicos y clínicos. Por esta razón, probamos una adaptación alemana de la Perceived Stress Scale de 10 ítems (PSS-10) para el ajuste del modelo y la invarianza de la medición en una gran muestra clínica y no clínica. MÉTODO: Realizamos (1) un análisis factorial confirmatorio múltiple (CFA) en 1.248 sujetos no clínicos y 575 pacientes ambulatorios, (2) invarianza de medición con CFA multigrupo, (3) correlaciones con constructos relevantes y (4) cálculos de la consistencia interna para la escala general y las subescalas Desvalidez y Autoeficacia. …

Evaluation der Sexual Sensation Seeking Scale: Ergebnisse einer repräsentativen deutschen Bevölkerungsumfrage

2021

ZusammenfassungBisherige Studien zu Sexual Sensation Seeking (SSS) und der Sexual Sensation Seeking Scale (SSSS) wurden überwiegend an nach dem Alter sowie dem Geschlecht selektierten Stichproben durchgeführt. In dieser Arbeit wurde die deutsche Version der SSSS anhand einer repräsentativen Umfrage an Männern und Frauen evaluiert, welche die gesamte Altersspanne der erwachsenen deutschen Bevölkerung umfasst. Die Gütekriterien und die Faktorenstruktur der deutschen Version der Sexual Sensation Seeking Scale wurden anhand einer repräsentativen Stichprobe von N=2420 Probanden (54% Frauen, 46% Männer) im Alter von 18–93 Jahren (M=50,44, SD=16,97) untersucht. Die SSSS zeigt gute Werte hinsichtli…

The Body Image Questionnaire-20 (FKB-20) is one of the most applied self-report measures in the context of body image assessment in German-speaking regions. A version of the FKB-20 capturing an ideal concept of body image is also available. A special property of the scale is its high sensitivity for individuals suffering from anorexia nervosa. The present research provided a short version of this scale (for both variants) and examined its validity in a representative sample (N= 2,347) of the German population. We utilized factor analysis methods to identify the optimal short scale of the measure, finding excellent model fit and reliability for a two-factor model (FKB-6) for both real and id…

Cross-cultural measurement invariance of the General Health Questionnaire-12 in a German and a Colombian population sample

2017

While the General Health Questionnaire, 12-item version (GHQ-12) has been widely used in cross-cultural comparisons, rigorous tests of the measurement equivalence of different language versions are still lacking. Thus, our study aims at investigating configural, metric and scalar invariance across the German and the Spanish version of the GHQ-12 in two population samples. The GHQ-12 was applied in two large-scale population-based samples in Germany (N = 1,977) and Colombia (N = 1,500). To investigate measurement equivalence, confirmatory factor analyses were conducted in both samples. In the German sample mean GHQ-12 total scores were higher than in the Colombian sample. A one-factor model …

Construct Validity and Population-Based Norms of the German Brief Resilience Scale (BRS).

2018

Abstract. The Brief Resilience Scale (BRS) measures the ability to recover from stress. To provide further evidence for construct validity of the German BRS and to determine population-based norms, a large sample (N = 1,128) representative of the German adult population completed a survey including the BRS and instruments measuring perceived stress and the resilience factors optimism, self-efficacy, and locus of control. Confirmatory factor analyses showed best model fit for a five-factor model differentiating the ability to recover from stress from the three resilience factors. On the basis of latent and manifest correlations, convergent and discriminant validity of the BRS were fair to g…

Short Form of the State-Trait Anger Expression Inventory-2

2020

Abstract. The purpose of the present study was to develop a short form of the State-Trait Anger Expression Inventory-2 (STAXI-2) based on the German STAXI-2. Item selection was performed based on exploratory factor analyses (EFA) using descriptive statistical parameters and content-related considerations on calibration samples ( N1 = 215, N2 = 310). The factorial structure of the final extracted scales was validated via confirmatory factor analyses (CFA) ( N3 = 216, N4 = 310). Overall, results present an economic and reliable questionnaire with a total length of 24 items: State Anger short scales Feeling Angry, Verbal Anger Impulse, and Physical Anger Impulse (3 items each), that can be ag…

Influence of the drawing process on the defect generation in multistep-index germanium-doped optical fibers

2009

International audience; Variation of germanium lone pair center (GLPC) concentration in germanosilicate multistep-index optical fibers and preforms was studied using confocal microscopy luminescence technique. The experimental results provide evidence that in the central core region ([Ge] ~11 wt. % ) of our specific canonical samples the ratio [GLPC]/[Ge] is five times larger in fiber than in preforms. The relative influence of the glass composition and of the drawing process on the generation efficiency of the GLPC defects that drive the glass photosensitivity is discussed. The radial distribution of these defects suggests a possible enhancement of the defect creation related to the intern…

“Not in Possession of Any Weltanschauung”: Otto Neugebauer’s Flight from Nazi Germany and His Search for Objectivity in Mathematics, in Reviewing, an…

2016

Two major factors have to be considered to account for Neugebauer’s “Weltanschauung”, in particular his apparent or real rejection of philosophical or political judgments. On the one hand, Neugebauer, as a mathematician and a historian, had to cope, with the double character of mathematics as a science in its continuity and universality, independent of time, and of mathematics as a characteristic and fundamental product of each individual culture. On the other hand emphasis has to be put on Neugebauer being torn between organizational work (institution building, reviewing, editing) and historical research. One has to consider the vicissitudes of Neugebauer’s long and eventful life, which wa…

VOT in French as a foreign language : A production and perception study with mono- and multilingual learners (German/Mandarin-Chinese)

2016

This study addresses the production of Voice Onset Time (VOT) in French as a foreign language (FFL). The learners are young multilingual learners who speak Mandarin Chinese as a heritage language along with German. To determine potential effects of the learners’ multilingual background, these multilingual learners were compared to three control groups: (1) monolingual German learners of FFL, (2) monolingual Mandarin Chinese learners of FFL, and (3) native speakers of French (L1). In addition, a perception experiment was carried out to find out to what extent the VOT values measured in the production data contribute to the perception of foreign accent. Our results show that multilingual lear…
