Konstruktion und Evaluation der dritten Version des Skalensystems zur Erfassung des Umweltbewusstseins (SEU-3)

'Das Skalensystem zur Erfassung des Umweltbewusstseins (SEU) wurden hinsichtlich des Itempools und in Bezug auf die erfassten Dimensionen ueberarbeitet und in mehreren Untersuchungen evaluiert; der Konstruktionsansatz basierte auf der klassischen Testtheorie. Das ueberarbeitete SEU behaelt das bewaehrte facettentheoretische Konzept der Vorgaengerversionen mit einer konzeptuellen und einer inhaltlichen Ebene bei, jedoch wurden die erfassten Dimensionen aufgrund frueherer Befunde veraendert. Ferner wurden eine Globalskala sowie vier verschiedene, ebenfalls eindimensionale Kurzversionen der Globalskala konstruiert und einer Qualitaetspruefung unterzogen. Basierend auf den Fragebogendaten mehrerer Stichproben (n=12 psychologische und n=22 Umweltexperten; n=104 Mitglieder in Umweltschutzorganisationen; Vergleichsstichprobe nicht engagierter Personen, n=203; vorwiegend studentische Stichprobe, n=64 mit jeweils drei Fremdeinschaetzungen pro Vpn) wurden Homogenitaet, Retest-Reliabilitaet nach ca. 5 1/2 Wochen, korrelative Struktur und verschiedene Validitaetsindikatoren erhoben. Die Ergebnisse sprechen fuer eine gute Qualitaet der Skalen und dokumentieren ihre Brauchbarkeit fuer Forschungszwecke. Die besten Werte erreichte die auf Basis der Uebereinstimmung zwischen Selbst-und Fremdbeurteilung konstruierte, aus 21 Items bestehende Globalskala UGK-V. Auf der Aggregatebene war es ferner moeglich, betraechtliche Anteile der Varianz der Stichproben-Mittelwerte der SEU-Items ueber von Experten erhobene Bewertungen der Item-Charakteristika aufzuklaeren.' (Autorenreferat)'Describes the revision (itempool and dimensions) and evaluation of a set of (German language) scales for assessing individual environmental attitudes, behavioral intentions and self-reported behavior. Besides belonging to one of these three scales, each item belongs to one of seven scales measuring environmentally relevant content areas (facet-approach). The revision was carried out according to the principles of the classical approach of test-construction. Furthermore, a global scale and four different, unidimensional short forms of the global scale were constructed. Results are presented using questionnaire responses from various samples (n=12 psychological and n=22 environmental experts, n=104 subjects who belong to conservation groups; n=203 subjects who do not belong to conservation groups; n=64 students with three peer-ratings for each subject; each sample comprised German female and male adults). Homogeneity, retest-reliability over approx. 5.5 weeks, correlations among scales and different indicators of validity are reported. These results demonstrate the quality of the constructed scales and indicate their usefulness for purposes of scientific research. The best scale according to the various indicators was a global, 21-item scale whose selection criterion had been the correlation between self- and peer-ratings. Furthermore, on an aggregate level, it was possible to explain significant proportions of the variance of item means in our various samples by using expert ratings of item characteristics.'

Simulation-Based Training of the Rapid Evaluation and Management of Acute Stroke (STREAM)-A Prospective Single-Arm Multicenter Trial

Introduction: Acute stroke care delivered by interdisciplinary teams is time-sensitive. Simulation-based team training is a promising tool to improve team performance in medical operations. It has the potential to improve process times, team communication, patient safety, and staff satisfaction. We aim to assess whether a multi-level approach consisting of a stringent workflow revision based on peer-to-peer review and 2-3 one-day in situ simulation trainings can improve acute stroke care processing times in high volume neurocenters within a 6 months period. Methods and Analysis: The trial is being carried out in a pre-test-post-test design at 7 tertiary care university hospital neurocenters in Germany. The intervention is directed at the interdisciplinary multiprofessional stroke teams. Before and after the intervention, process times of all direct-to-center stroke patients receiving IV thrombolysis (IVT) and/or endovascular therapy (EVT) will be recorded. The primary outcome measure will be the door-to-needle time of all consecutive stroke patients directly admitted to the neurocenters who receive IVT. Secondary outcome measures will be intervention-related process times of the fraction of patients undergoing EVT and effects on team communication, perceived patient safety, and staff satisfaction via a staff questionnaire. Interventions: We are applying a multi-level intervention in cooperation with three STREAM multipliers from each center. First step is a central meeting of the multipliers at the sponsor's institution with the purposes of algorithm review in a peer-to-peer process that is recorded in a protocol and an introduction to the principles of simulation training and debriefing as well as crew resource management and team communication. Thereafter, the multipliers cooperate with the stroke team trainers from the sponsor's institution to plan and execute 2-3 one-day simulation courses in situ in the emergency department and CT room of the trial centers whereupon they receive teaching materials to perpetuate the trainings
