T1  - The adaptation of the Short Dark Triad personality measure

N2  - 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.

T1  - The reduced discounting inventory
BT  - construction and initial validation
JF  - Current psychology
N2  - In two studies, the aim of this research was to develop and validate a Polish version of the reduced Discounting Inventory. In Study 1 (N = 623) items extraction from the 48-item DI was based upon item-total correlation and items with highest coefficients were considered. The reduced Discounting Inventory resulted in sixteen items. Cronbach's a coefficient was .78, and the item-total correlations ranged between .59 and .77. The correlation between Polish versions of reduced Discounting Inventory and longer 48-item Discounting Inventory was .85. Next, the reduced Discounting Inventory was evaluated in terms of factorial and construct validity. The structure of the instrument was analysed by Confirmatory Factor Analyses procedure. It indicated that the four-factor structure had the best fit to the data. Additionally, we show that this reduced Discounting Inventory closely parallels the longer 48-item inventory its relation to traditional discounting measures using pairs of hypothetical choices (expect for the delay discounting subscale). Finally, in study 2, the test-retest reliability of the reduced Discounting Inventory over a 3-month interval was assessed (247 subjects of the 623 individuals who participated in Study 1). Results indicated good stability of the reduced measure (>= .88). It is concluded that the reduced Discounting Inventory has notable psychometric properties and that it can serve as an alternative measure of discounting when situations do not allow the use of longer inventories.
