Objetivos: Este estudio intenta examinar perfiles de personalidad de empleados con personal a cargo. Se examinan diferencias en la presencia de rasgos negativos -maquiavelismo, narcisismo, psicopatía- según variables sociodemográficas y, además, la relación con variables psicológicas (bienestar, sintomatología psicopatológica, satisfacción y performance laboral). Los resultados se analizan desde el modelo Tríada Oscura -Dark Triad- (Palthus & Williams, 2002). Participantes: 119 empleados con personal a cargo (49 hombres, 70 mujeres); edad promedio: 45.8 años (DE=9.76). La mayoría residía en Buenos Aires (85.7%). Materiales: Encuesta sociodemográfica y de datos laborales; DTS, SCL-90-R; MHC. Resultados: Primero, en cuanto a diferencias de acuerdo a variables sociodemográficas se halló una mayor presencia del rasgo maquiavelismo en hombres líderes [t = 2.01, p < .05], y una mayor presencia del rasgo psicopatía en los menores de 35 años [t = 2.37, p < .05]. Segundo, se halló que a mayor presencia de maquiavelismo se observa mayor nivel de sintomatología psicopatológica general [r = .22*]. A su vez, se registró que a mayor presencia de narcicismo se observa menor nivel de bienestar social [r = -.21*]. Por último, no se halló relación entre los rasgos negativos y la autopercepción de satisfacción y performance laboral.

Differences in the presence of negative traits -machiavelism, narcissism, psychopathy- are examined according to sociodemographic variables. In addition, the relationship with psychological variables (well-being, psychopathological symptoms, satisfaction and job performance) was studied. The theoretical perspective for the analysis of the results is the Dark Triad model (Palthus & Williams, 2002). Participants: 119 employees with staff in charge (49 men, 70 women); average age: 45.8 years (SD = 9.76). Most of them resided in Buenos Aires (85.7%). Materials: Sociodemographic and job data Survey; DTS, SCL-90-R; MHC. Results: Firstly, in terms of differences according to sociodemographic variables, a greater presence of the Machiavellian trait was found in men leaders [t = 2.01, p <.05], and a greater presence of the psychopathy trait was found in employees who are under 35 years [t = 2.37, p < .05]. Secondly, a positive correlation was found between Machiavellianism and psychopathological symptoms [r = .22 *]. Furthermore, a negative correlation was found between narcissism and social well-being [r = -.21 *]. Finally, no correlation was found between negative traits and self-perception of satisfaction and job performance. Keywords Negative traits - Leaders - Psychopathological symptoms - Well-
