Making and maintaining relationships through the prism of the dark triad traits: A longitudinal social network study.

OBJECTIVE: We investigated how Dark Triad traits influence the development and maintenance of social relations. METHOD: Participants completed the Short Dark Triad questionnaire and a measure of social relations at three time points: at the beginning of their first year in high school, 3 months later, and at the end of their first year. We investigated whether the Dark Triad traits are stable over time using Multilevel Modeling (N = 265; 59.6% girls), and how Dark Triad traits predict incoming and outgoing agentic and communal relations using Temporal Exponential Random Graph Models (N = 192; 60.4% girls). RESULTS: Overall, the Dark Triad traits were stable over a one-year period. Narcissism did not predict an increase in communal and agentic relations in the short-term, but predicted slightly less incoming communal and more agentic relations in the long-term. In the short-term, Machiavellianism predicted a small increase while psychopathy predicted a small decrease in the incoming agentic and communal relations. In the long-term, however, neither Machiavellianism nor psychopathy was a significant predictor of any incoming relations. CONCLUSIONS: Our results shed new light on the dynamics of making and maintaining social relations through the prism of the Dark Triad traits.

Mindfulness and Compliance: The Way We Make Requests Influences Compliance With the Foot-in-the-Door Strategy.

The foot-in-the-door effect is considered more effective when a time lapse occurs between performing an initial, smaller request and being asked a second request. It has been hypothesized that mindfulness moderates the effectiveness of two versions of the strategy - time-delay and no-delay foot-in-the-door. The greater magnitude of time-delay foot-in-the-door is considered to be connected with increased mindfulness. The aim of this study was to verify the assumption concerning mindfulness as a state triggering time-delay foot-in-the-door. In a field experiment ( N = 249), we manipulated the time lapse and kind of reason (real, placebic, and no reason) accompanying a difficult or less difficult target request. This extended Langer et al. replication indicates that time-delay foot-in-the-door is indeed greater after mindfulness activation.
