Dark Triad traits (narcissism, psychopathy, and Machiavellianism) are linked to the pursuit of short-term mating strategies, but they may have differential effects on actual mating success in naturalistic scenarios: Narcissism may be a facilitator for men's short-term mating success, while Machiavellianism and psychopathy may be detrimental. To date, little is known about the attractiveness of Dark Triad traits in women. In a speed-dating study, we assessed participants' Dark Triad traits, Big Five personality traits, and physical attractiveness in N = 90 heterosexual individuals (46 women and 44 men). Each participant rated each partner's mate appeal for short-and long-term relationships. Across both sexes, narcissism was positively associated with mate appeal for short-and long-term relationships. Further analyses indicated that these associations were due to the shared variance among narcissism and extraversion in men and narcissism and physical attractiveness in women, respectively. In women, psychopathy was also positively associated with mate appeal for short-term relationships. Regarding mating preferences, narcissism was found to involve greater choosiness in the rating of others' mate appeal (but not actual choices) in men, while psychopathy was associated with greater openness towards short-term relationships in women.

With the PERMA theory, Seligman (2011) postulates that well-being consists of five independently measurable factors: Positive Emotions (P), Engagement (E), Positive Relationships (R), Meaning (M) and Accomplishment (A). The PERMA-Profiler provides the first questionnaire, which measures all five well-being domains in an economical and reliable way. In order to test the validity of the questionnaire in German speaking countries, a German version of the PERMA-Profiler was developed and evaluated in a large sample (N = 854). The results provide evidence for acceptable reliability, very good construct validity (factorial and convergent) and first indications for measurement invariance, for both gender and nationality. Compared to three theoretically competing models, the inter-correlated Five-Factor Model turned out to be the most appropriate statistical model to describe the collected data. It revealed the best trade-off between model fit, parsimony and theoretical interpretability. Our results support the hypothesis of a multidimensional PERMA theory, which gives a closer insight in at least some of the building blocks of well-being. Therefore, the PERMA theory can be seen as a useful extension to a unidimensional subjective well-being approach. Like the English original, the German version of the PERMA-Profiler allows to measure well-being economically across multiple well-being domains. Therefore, the PERMA-Profiler can be recommended as a valid well-being screening instrument for the German speaking adult population.
