Zusammenfassung. Angstsensitivität ist ein Konstrukt, das bei der Ätiologie von Angststörungen relevant ist und sich in der internationalen Forschung zunehmender Beliebtheit erfreut. Bisher existiert jedoch kein aktuelles deutschsprachiges Instrument mit einer robusten faktoriellen Validität zur Erfassung von Angstsensitivität. Daher zielte diese Studie darauf ab, die psychometrische Qualität einer deutschsprachigen Version des Anxiety Sensitivity Index-3 ( Taylor et al., 2007 ) zu überprüfen. In die Auswertung gingen Daten von insgesamt N = 5477 Personen aus drei Ländern ein. Die Ergebnisse belegen eine zufriedenstellende Messgenauigkeit, faktorielle Validität und Konstruktvalidität der Übersetzung. Zudem konnte die Messinvarianz mit der englischsprachigen Originalversion gezeigt werden. Die praktischen und theoretischen Implikationen der Ergebnisse werden diskutiert.
The ratio of the lengths of the second and fourth finger (2D:4D) has been proposed to index prenatal exposure to androgens. Different methods have been utilized to measure digit ratio, however, their measurement precision and economy have not been systematically compared yet. Using different indirect methods (plastic ruler, caliper, computer software), three independent raters measured finger lengths of 60 participants. Generally, measurement precision (intraclass correlation coefficient, technical error of measurement, and relative technical error of measurement) was acceptable for each method. However, precision estimates were highest for the computer software, indicating excellent measurement precision. Estimates for the caliper method were somewhat lower followed by ruler which had the lowest precision. On the contrary, the software-based measurements took somewhat longer to complete than the other methods. Nonetheless, we would favor the use of these tools in digit ratio research because of their relative superior reliability which could be crucial when associations with other variables are expected to be low to moderate or sample size is limited. Software offers several promising opportunities that may contribute to an accurate identification of the proximal finger crease (e.g., zooming, adjusting contrast, etc.).
For groups of persons with low or medium levels of education, Big Five personality scales typically yield scores that poorly replicate the idealized Big Five factor pattern. On the basis of representative samples of German adults, Rammstedt et al. have demonstrated that correcting each person's score for acquiescence eliminates this problem. In the present 18-country study using large samples representative of each country's adult population, we found that, in all cases, correcting for acquiescence did indeed improve the congruence of factor loadings with an idealized Big Five pattern. However, although this correction led to acceptably high correspondence levels in all countries classified as individualistic, this was not always true for non-individualistic countries. Possible reasons for this finding are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
