Die REFS erfasst im englischsprachigen Original die Selbstwirksamkeit von Schiedsrichterinnen und Schiedsrichtern mit den Subskalen Wissen über das Spiel, Entscheidungsfindung, Druck und Kommunikation. Die Items wurden mit Hilfe der Übersetzung-Rückübersetzung ins Deutsche übertragen. Die Struktur und die psychometrischen Eigenschaften der deutschen Items wurden anhand einer Stichprobe aus 265 deutschsprachigen Fußballschiedsrichterinnen und -schiedsrichtern überprüft. Da die im englischsprachigen Original vorgeschlagene Skalenzuordnung der REFS nach der Übersetzung ins Deutsche nicht replizierbar war, wurden Items mit mangelhaften Skaleneigenschaften aus der deutschsprachigen REFS-Version (REFS-D) ausgeschlossen. Das Resultat der Analysen ist eine Skala mit acht Items, die sich drei Subskalen, Spielumsetzung, Druck und Kommunikation, zuordnen lassen. Die REFS-D weist zufriedenstellende interne Konsistenzen und signifikante mittelhohe Korrelationen mit allgemeiner Selbstwirksamkeit auf. Trotz einiger Einschränkungen stellt die REFS-D als ökonomische Skala einen Ansatzpunkt für zukünftige Forschung dar. N2 - The purpose of the present article was to evaluate statistically and validate a German version of the Referee Self-Efficacy Scale (REFS). The English REFS assesses referee self-efficacy and consists of the scales Game Knowledge, Decision-Making, Pressure, and Communication. Data from 265 soccer referees was used to evaluate the structure and psychometric properties of the German items. Since we could not replicate the original dimension structure, we excluded items from the German REFS (REFS-D) that showed poor item characteristics. Analyses resulted in a short REFS-D consisting of eight items, subdivided into three dimensions: game realization, pressure, and communication. Results show acceptable internal consistencies. All three subscales of the REFS-D showed significant moderate correlations with general self-efficacy. Despite some limitations, the REFS-D represents an economic questionnaire and starting point for future research.

We have chosen a dual-system approach to social information processing to investigate the hypothesis that situated decisions between behavioral alternatives form a functional link between automatic and reflective evaluations and the time spent on exercise. A new questionnaire is introduced to operationalize this link. A reaction-time based evaluative priming task was used to test participants' automatic evaluations. Affective and cognitive reflective evaluations, as well as exercising time, were requested via self-report. Path analyses suggest that the affective reflective (beta =.71) and the automatic evaluation (beta =.15) independently explain situated decisions, which, in turn (beta =.60) explain time spent on exercise. Our findings highlight the concept of contextualized decisions. They can serve as a starting point from which the so far seldom investigations of automatic cognition and affect in exercise can be integrated with multitudinous results from studies on reflective psychological determinants of health behavior.

We assume that referees' decision-making in contact situations mainly relies on intuitive processing. For improving intuitive decisions, feedback on the correctness of decisions is essential; explanations are not required (Hogarth, 2008). Referees participating in SET watch videos, make decisions, and receive feedback. Evidence of the training's effectiveness was obtained in two experiments with soccer players and expert referees. Immediate feedback on the correctness of decisions without further explanations was sufficient for increasing decision accuracy. Results illustrate that SET is a promising tool for complementing referees' training.

We propose that standards can be established by video training-programs. Thirty-three German elite basketball referees participated in an online experiment. Feedback during a learning phase influenced decisions (foul vs. no call) in a subsequent test phase. These results provide a starting point for further investigations into establishing standards for referees. They suggest that establishing standards for referees' decisions in ambiguous situations may be a worthwhile approach for improving the quality of referees' decisions.

N2 - Models employed in exercise psychology highlight the role of reflective processes for explaining behavior change. However, as discussed in social cognition literature, information-processing models also consider automatic processes (dual-process models). To examine the relevance of automatic processing in exercise psychology, we used a priming task to assess the automatic evaluations of exercise stimuli in physically active sport and exercise majors (n = 32), physically active nonsport majors (n = 31), and inactive students (n = 31). Results showed that physically active students responded faster to positive words after exercise primes, whereas inactive students responded more rapidly to negative words. Priming task reaction times were successfully used to predict reported amounts of exercise in an ordinal regression model. Findings were obtained only with experiential items reflecting negative and positive consequences of exercise. The results illustrate the potential importance of dual-process models in exercise psychology.
