Factor structure and psychometric properties of the german version chronic uncertainty scale (CU-20).

Background: The experience of uncertainty is ubiquitous and universal across the globe. Many available tools measuring uncertainty are focused on one aspect of uncertainty, e.g.

Psychometric properties and validation of the English version Giessen Subjective Complaints List (GBB-8).

Background: The present study investigated the psychometric properties of the newly developed English version of the Giessen Subjective Complaint List-8 (GBB-8), a questionnaire assessing psychosomatic symptoms with regard to exhaustion, gastrointestinal, musculoskeletal and cardiovascular.

Methods: A U.S.

Fight or flight: The effect of heart rate reactivity on acute stress-induced food intake.

The 'fight-or-flight-reaction' describes the suppression of all irrelevant functions like food intake during the acute stress response. However, heart rate reactivity and food intake under acute stress has not been investigated. Therefore, the aim of this study was to investigate the effect of high and low heart rate reactivity on food intake following an acute laboratory stress paradigm in individuals with healthy weight.

Perceived Stress Scale (PSS-10) psychometric properties in migrants and native Germans.

Background: With the increasing diversity of the German population, it is important to test the psychometric validity and reliability of the German version Perceived Stress Scale (PSS-10) specifically between German natives and residents with a migration background.

Methods: Using nationally representative data (N = 2527), this study conducted an Exploratory Factor Analysis (EFA) to determine the most appropriate factor structure, a Multi-Group Confirmatory Factor Analysis (MGCFA) to compare the validity of the two-factor structure and tested the PSS-10 measurement invariance between the German native and migrant sub-samples. Lastly, reliability of the PSS-10 was examined via Cronbach's alpha, omega and individual item analyses across the two sub-samples.

Air Quality and Chronic Stress: A Representative Study of Air Pollution (PM2.5, PM10) in Germany.

Objective: With rising attention on climate change and the aftermath of burning fossil fuels, there is much concern regarding the effects of air pollution on physical and psychological health. However, the relationship between chronic stress and air pollution is relatively unexplored in humans.

Methods: By combining German representative data with national pollution data and using step-wise regression analyses, this study investigates how air pollution (particulate matter 2.
