BT - a pilot study BT - Ergebnisse einer Pilotstudie JF - Zeitschrift für Klinische Psychologie und Psychotherapie N2 - Background: Under the new psychotherapy law in Germany, standardized patients (SPs) are to become a standard component inpsychotherapy training, even though little is known about their authenticity.Objective:The present pilot study explored whether, followingan exhaustive two-day SP training, psychotherapy trainees can distinguish SPs from real patients. Methods: Twenty-eight psychotherapytrainees (M= 28.54 years of age,SD= 3.19) participated as blind raters. They evaluated six video-recorded therapy segments of trained SPsand real patients using the Authenticity of Patient Demonstrations Scale. Results: The authenticity scores of real patients and SPs did notdiffer (p= .43). The descriptive results indicated that the highest score of authenticity was given to an SP. Further, the real patients did notdiffer significantly from the SPs concerning perceived impairment (p= .33) and the likelihood of being a real patient (p= .52). Conclusions: The current results suggest that psychotherapy trainees were unable to distinguish the SPs from real patients. We therefore stronglyrecommend incorporating training SPs before application. Limitations and future research directions are discussed. N2 - Theoretischer Hintergrund: Mit dem neu eingeführten Direktstudium für zukünftige Psychotherapeut_innen (PiA) wirdder Einsatz von standardisierten Patient_innen (SP) in der Lehre zunehmen, obwohl die Authentizität der Rollendarstellungen durch SPempirisch bislang kaum untersucht wurde. Ziel der vorliegenden Studie war es daher zu untersuchen, ob SP trainiert werden können, dassPsychotherapeut_innen in Ausbildung (PiA) SP von realen Patient_innen nicht unterscheiden können. Methode: Insgesamt nahmen 28 PiA(M= 28.54 Jahre,SD= 3.19) als verblindete Rater teil. Sie haben sechs Therapiesitzungen von trainierten SP und realen Patient_innen mitder Skala Authentizität von Patientendarstellungen bewertet. Ergebnisse: Die Authentizitätswerte von SP unterschieden sich nicht signifi-kant von realen Patient_innen (p= .43). Deskriptive Ergebnisse legen nahe, dass ein SP im Schnitt am authentischsten bewertet wurde.Darüber hinaus unterschieden sich SP und reale Patient_innen nicht hinsichtlich der wahrgenommenen Beeinträchtigung (p= .33) sowie derWahrscheinlichkeit, als reale/r Patient_in bewertet zu werden (p= .52). Fazit: Die vorliegenden Ergebnisse legen nahe, dass PiA SP vonrealen Patient_innen nicht unterscheiden konnten. Daher legen wir ein ausführliches Training der SP nahe, bevor sie für Studium und Lehreeingesetzt werden. Die Limitationen sowie zukünftige Forschungsideen werden diskutiert.

Eine Verstetigung universitär geprägter Forschung und Modellierung in der praxisnahen Anwendung im schulischen Kontext bietet Potentiale nachhaltiger Professionalisierung. Die Stärkung reflexionsbezogener Kompetenzen durch Empirie und Anwendung scheint eine phasenübergreifende Herausforderung der Lehrkräftebildung zu sein, die es zu bewältigen gilt. Ziele des Tagungsbandes Reflexion in der Lehrkräftebildung sind eine theoretische Schärfung des Konzeptes „Reflexive Professionalisierung“ und der Austausch über Fragen der Einbettung wirksamer reflexionsbezogener Lerngelegenheiten in die Lehrkräftebildung. Forschende und Lehrende der‚ drei Phasen (Studium, Referendariat sowie Fort- und Weiterbildung) der Lehrkräftebildung stellen Lehrkonzepte und Forschungsprojekte zum Thema Reflexion in der Lehrkräftebildung vor und diskutieren diese. Gemeinsam mit Teilnehmenden aller Phasen und von verschiedenen Standorten der Lehrkräftebildung werden zukünftige Herausforderungen identifiziert und Lösungsansätze herausgearbeitet.

So far, video consultations have been limited to pilot projects and have not yet been comprehensively implemented. The present study addresses potentials of video consultations and challenges that may arise during the implementation of medical video consultations. Methods: Twenty-one guided interviews (pre-implementation: n = 13; post-implementation: n = 8) were conducted with a total of 13 participants (physicians, nurses and medical technical assistants). The data was analyzed using qualitative content analysis. The results were contrasted in a pre-post analysis. Results: Almost all of the interviewees' expectations regarding video consultations described prior to implementation have been met: time savings, improved communication, reduction of information breaks and increase in the quality of care. After implementation, other unexpected advantages of telemedical care became apparent, such as the possibility of regular monitoring or the improved ability to plan routine visits without interrupting the daily schedule. At the same time, the implementation of video consultations is associated with the following challenges: defining responsibilities, acquiring experience in handling video consultation tools, providing for sufficient qualification and training, dealing with new billing modalities as well as missing links between nursing documentation and medical information systems. Discussion: Video consultations can improve health care routines in nursing homes, lead to a wider availability of medical services, and contribute to improving patient safety and the quality of care. However, various aspects and contextual factors need to be addressed when implementing video consultations. These include: implementation of technical requirements, initial training with test consultations, continuous interactive development of potential fields of application, and the definition of the respective responsibilities of caregivers, physicians and medical assistants.
