Individuals (N = 142) completed the assessments with hypothetical and potentially real effort discounting tasks, and their hypothetical or potentially real consequences. The data obtained from the experiment reported here suggest that hypothetical conditions yield patterns of discounting that mirror those for potentially real effort tasks and outcomes. However, this finding also leaves open the possibility that the degree of discounting may change together with the repeated exposure to the consequences of decisions, or the counterbalanced order of hypothetical and potentially real tasks.}, language = {en} } @article{MaleszaOstaszewskiBuechneretal.2019, author = {Malesza, Marta and Ostaszewski, Paweł and B{\"u}chner, Susanne and Kaczmarek, Magdalena C.}, title = {The adaptation of the Short Dark Triad personality measure}, series = {Current psychology}, volume = {38}, journal = {Current psychology}, number = {3}, publisher = {Springer}, address = {New York}, issn = {1046-1310}, doi = {10.1007/s12144-017-9662-0}, pages = {855 -- 864}, year = {2019}, abstract = {This research was designed to adapt and investigate the psychometric properties of the Short Dark Triad measure (Jones and Paulhus Assessment, 21(1), 28-41, 2014) in a German sample within four studies (total N=1463); the measure evaluates three personality dimensions: narcissism, psychopathy, and Machiavellianism. The structure of the instrument was analysed by Confirmatory Factor Analyses procedure. It indicated that the three-factor structure had the best fit to the data. Next, the Short Dark Triad measure was evaluated in terms of construct, convergent and discriminant validity, internal consistency ( .72), and test-retest reliability during a 4-week period ( .73). Concurrent validity of the SD3 was supported by relating its subscales to measures of the Big Five concept, aggression, and self-esteem. We concluded that the Short Dark Triad instrument presented high cross-language replicability. The use of this short inventory in the investigation of the Dark Triad personality model in the German language context is suggested.}, language = {en} }
