This study aims at assessing to which extent these streamflow trends can be attributed to changes in air temperature or precipitation. The analysis includes a data-based approach using multiple linear regression and a simulation-based approach using a hydrological model. The hydrological model considers changes in both glacier area and surface elevation. It was calibrated using a multiobjective optimization algorithm with calibration criteria based on glacier mass balance and daily and interannual variations of discharge. The individual contributions to the overall streamflow trends from changes in glacier geometry, temperature, and precipitation were assessed using simulation experiments with a constant glacier geometry and with detrended temperature and precipitation time series. The results showed that the observed changes in streamflow were consistent with the changes in temperature and precipitation. In the Sari-Djaz catchment, increasing temperatures and related increase of glacier melt were identified as the dominant driver, while in the Kakshaal catchment, both increasing temperatures and increasing precipitation played a major role. Comparing the two approaches, an advantage of the simulation-based approach is the fact that it is based on process-based relationships implemented in the hydrological model instead of statistical links in the regression model. However, data-based approaches are less affected by model parameter and structural uncertainties and typically fast to apply. A complementary application of both approaches is recommended.

T1 - Können Psychotherapeut*innen in Ausbildung standardisierte Patient*innen von realen Patient*innen unterscheiden? 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.
