摘要：background The Dark Triad (DT;Machiavellianism,narcissism,psychopathy) refers to three distinct but interrelated socially undesirable traits which are associated with an antago_nistic and exploitative strategy of conduct.The aim of the current study was to investigate the relationships between the DT traits and momentary affective states using a lon?gitudinal approach.participants and procedure University students (N = 81) completed personality mea?sures and participated in an 8-day experience-sampling study.Subjects provided n = 2572 responses.Multilevel analyses were used to assess relationships between the DT and affect.results All the DT traits were associated with negative affect: the two psychopathy dimensions (boldness and meanness) negatively,and the remaining traits positively.Boldness and grandiose narcissism were associated with positive affect.The presence of others differentiated the relation?ships between Machiavellianism and meanness and nega_tive affective states.conclusions The findings showed a tendency to experience more nega?tive affect in everyday life in people with higher levels of grandiose and vulnerable narcissism,Machiavellianism,and disinhibition.
