Knapp ein Drittel der jährlichen Trainingsausfallzeiten werden auf CURS zurückgeführt. In der Entstehung von chronischen Schmerzen ist ein multifaktorielles Ätiologiemodell mit einem signifikanten Einfluss psychosozialer Risikofaktoren evident. Obwohl dies in der Allgemeinbevölkerung bereits gut erforscht ist, gibt es in der Sportwissenschaft vergleichsweise wenige Arbeiten darüber. Dieses Thema wird daher in drei Multicenterstudien und zahlreichen Teilstudien des MiSpEx-Netzwerks (Medicine in Spine-Exercise-Network, Förderzeitraum 2011 – 2018) aufgegriffen. Entsprechend der Empfehlung einer frühzeitigen Diagnostik von Chronifizierungsfaktoren in der „Nationalen Versorgungsleitlinie Kreuzschmerz“, beschäftigt sich das Netzwerk u. a. mit der Überprüfung, Entwicklung und Evaluation diagnostischer Möglichkeiten. Der vorliegende Beitrag beschreibt die Entwicklung einer Diagnostik von psychosozialen Risikofaktoren, die einerseits eine Einschätzung des Risikos der Entwicklung von CURS und andererseits eine individuelle Zuweisung zu (Trainings)Interventionen erlaubt. Es wird die Entwicklungsrationale beschrieben und dabei verschiedene methodische Herangehensweisen und Entscheidungssequenzen reflektiert. N2 - Chronic nonspecific low back pain (CLBP) is one of the most common pain syndromes globally. Attributing to one third of missed training days, CLBP can seriously affect athletes’ careers. Studies in the general population show a multifactorial etiology with significant influence of psychosocial risk factors in the development of CLBP. As less is known about this phenomenon in athletes, the MiSpEx Network (Medicine in Spine Exercise, funded from 2011 to 2018) has conducted three multicenter studies and numerous substudies investigating this topic. The network has been concerned with the testing, development, and evaluation of diagnostics, in accordance with the recommendation of the German National Treatment Guidelines for CLBP that risk factors be recognized and treated early. Our article describes the development of a diagnostic tool for psychosocial risk factors that allows (medical) practitioners to predict the occurrence of CLBP and to suggest individualized (trainings) interventions. We present the methodological approach and discuss various methodological issues.

We evaluate the shape parameter (GEV), obesity index, Gini index and upper tail ratio (UTR) against a novel benchmark of tail heaviness - the surprise factor. Sensitivity analyses to sample size and changes in scale-to-location ratio are carried out in bootstrap experiments. The UTR replicates the surprise factor best but is most uncertain and only comparable between records of similar length. For samples with symmetric Lorenz curves, shape parameter, obesity and Gini indices provide consistent indications. For asymmetric Lorenz curves, however, the first two tend to overestimate, whereas Gini index tends to underestimate tail heaviness. We suggest the use of a combination of shape parameter, obesity and Gini index to characterize tail heaviness. These indicators should be supported with calculation of the Lorenz asymmetry coefficients and interpreted with caution.

Diagnostic indicators that allow comparison across these models can help describe and explain differences in model projections. This increases transparency and comparability. Earlier, the IAM community has developed an approach to diagnose models (Kriegler (2015 Technol. Forecast. Soc. Change 90 45–61)). Here we build on this, by proposing a selected set of well-defined indicators as a community standard, to systematically and routinely assess IAM behaviour, similar to metrics used for other modeling communities such as climate models. These indicators are the relative abatement index, emission reduction type index, inertia timescale, fossil fuel reduction, transformation index and cost per abatement value. We apply the approach to 17 IAMs, assessing both older as well as their latest versions, as applied in the IPCC 6th Assessment Report. The study shows that the approach can be easily applied and used to indentify key differences between models and model versions. Moreover, we demonstrate that this comparison helps to link model behavior to model characteristics and assumptions. We show that together, the set of six indicators can provide useful indication of the main traits of the model and can roughly indicate the general model behavior. The results also show that there is often a considerable spread across the models. Interestingly, the diagnostic values often change for different model versions, but there does not seem to be a distinct trend.

Dabei ist entscheidend, dass Lehrkräfte in der Lage sind diese Kinder zu identifizieren, um pädagogisch adäquat handeln zu können. Aufgrund der nach innen gerichteten Symptome stellt das Erkennen internalisierender Probleme eine große Herausforderung dar. Zur Diagnostik werden vorwiegend standardisierte Fragebögen eingesetzt, welche den Schulkontext sowie spezifische Altersgruppen und die damit einhergehende Veränderlichkeit von Emotionswahrnehmungen der betroffenen Kinder nur unzureichend berücksichtigen. Dieser Beitrag präsentiert die Ergebnisse einer Interviewstudie und diskutiert den Einsatz von Interviews als Methode zur Identifikation emotional relevanter Situationen aus der Perspektive von Kindern. Die Ergebnisse sollen der Ableitung alters- und kontextspezifischer Items dienen, um die Diagnostik internalisierender Schwierigkeiten weiterzuentwickeln. N2 - Children with internalizing problems face challenging academic as well as social situations in the school context. It is crucial that teachers are able to identify these children to act adequately. Due to the inwardly directed symptoms, identifying such problems is a major challenge. Standardized questionnaires, which are predominantly used for diagnosis, do not sufficiently consider the school context as well as specific age groups and the associated variability of emotion perceptions of the affected children. This paper presents the results of an interview study and discusses the use of interviews as a method for identifying emotionally relevant situations from the perspective of children. The results will be used to derive age- and context-specific items to further develop the diagnosis of internalizing difficulties.
