Abstract
Zusammenfassung. Die Relevanz des Konstruktes Optimismus für eine Vielzahl psychologischer und medizinischer Bereiche ist in zahlreichen Studien eindrucksvoll demonstriert worden. Das in der Forschung mit Abstand am häufigsten eingesetzte Messinstrument zur Erfassung des dispositionellen Optimismus ist der Life-Orientation-Test (LOT-R). Die deutsche Übersetzung des LOT-R wird vorgestellt und anhand von Daten von 4938 Personen im Alter von 18-101 Jahren geprüft. Es werden psychometrische Kennwerte, Gütekriterien und Normwerte sowohl für die Subskalen Optimismus und Pessimismus als auch für die Gesamtskala berichtet. Damit liegt eine verbesserte Basis für den Forschungseinsatz und die vergleichende Bewertung von Befunden mit diesem Instrument vor.
Abstract. The relevance of the construct optimism in a variety of psychological and medical domains has been convincingly demonstrated by numerous studies. The most commonly used instrument for measuring dispositional optimism in psychological research is the Life-Orientation-Test (LOT-R). The German translation of the LOT-R is introduced and tested using a sample of 4938 individuals ranging in age from 18-101 years. Psychometric properties and norms for the optimism and pessimism subscale as well as for the LOT-R score are reported. The data provides an improved basis for the use of the instrument in research settings and for the interpretation of results.
