The psychological meaning of integrity test scores has been explored predominantly in relation to the five-factor model of personality (FFM). Two alternative positions on this topic can be identified in the literature which state, respectively, that integrity tests measure (a) a higher-order factor of personality covering three FFM dimensions or (b) a linear composite of numerous facets from various domains within the FFM. An empirical test of these alternative positions, using structural equation modeling, revealed that the value of both views depended on the type of integrity test examined. With a personalitybased integrity test, position (a) had to be refuted, whereas position (b) was strongly supported. There was also more supportive evidence for position (b) with an overt test, but the difference was far less pronounced than for the personality-based measure. Possible consequences for theories on the role of personality in personnel selection are discussed.

As previous meta-analyses have focused almost solely on English-speaking regions, this study presents the first systematic meta-analytical examination of the predictive validity of assessment centers (ACs) conducted in German-speaking regions. It summarizes 24 validity coefficients taken from 19 studies (N = 3,556), yielding a mean corrected validity of ρ = .396 (80% credibility interval .235 ≤ ρ ≤ .558). ACs with different purposes and different kinds of criterion measures were analyzed separately. Furthermore, target group (internal vs. external candidates), average age of the assessees, inclusion of intelligence measures, number of instruments used, AC duration, as well as time elapsed between AC and criterion assessment were found to moderate the validity.

Zusammenfassung. Die wiederholte Bearbeitung eines identisch oder parallel konstruierten kognitiven Fähigkeitstests führt in der Regel zu einer deutlich verbesserten Leistung. Zunächst wird ein Überblick zur bestehenden empirischen Befundlage zu Testwiederholungseffekten sowie zu möglichen Verursachungen gegeben. Als kognitionspsychologischer Anknüpfungspunkt dient hierbei Ackermans (1988) Theorie zum Fertigkeitserwerb. Danach wird in der vorgestellten Studie am Beispiel eines Tests zum räumlichen Vorstellungsvermögen (Relative Position, REP) die Auswirkung von Testwiederholungseffekten auf die Testleistung der Probanden sowie die Testreliabilität und -validität untersucht. 156 Bewerber in einem Auswahlprogramm für Nachwuchsflugzeugführer bearbeiteten insgesamt zehnmal hintereinander das jeweils fünfminütige Testverfahren. Nach der fünften Testdurchführung weisen die erzielten Zuwächse keine praktische Bedeutsamkeit mehr auf. Reliabilität und Validität des Tests werden durch die Übung nicht beeinträchtigt, sondern scheinen eher noch anzusteigen. Konsequenzen für die diagnostische Anwendung werden diskutiert.

Malignant melanoma of the uvula and soft palate is very rare. We describe a case demonstrating the typical aggressive behavior of mucosal melanoma in contrast to cutaneous melanoma. Regional lymph node and distant metastases often develop rapidly in this type of melanoma. Despite aggressive surgical approaches, other treatment options are often limited and usually palliative. Therefore, early diagnosis is critical in patients with mucosal melanoma.
