Dispositional authenticity is a narrow personal trait, describing personal ability to live in accord with their inner self and resist the external influences. The tripartite model of authenticity comprises three components: authentic living, not accepting external influence and lack of self-alienation. In the current research we performed two empirical studies, aiming to mark dispositional authenticity on a map of personality. The objectives of these studies were 1) to clarify the ontological status of authenticity as a trait by correlating it with other personality features, 2) to determine the pattern of traits that are most favorable or unfavorable for its manifestation, and 3) to find its possible predictors. We used the Russian version of the Authenticity scale (Wood et al, 2008; adapted by S. Nartova-Bochaver et al., 2020) as a main research instrument. In our first study (n = 271) we used the Russian version of the Temperament and Character Inventory (TCI-140) (Cloninger et al., 1993; adapted by N. Almaev, L. Ostrovskaya, 2005). It was found that Self-Directedness as a character trait is a key predictor of authenticity. Somewhat weaker authenticity can be explained by the features of temperament –low Harm Avoidance and Reward Dependence. Novelty Seeking and Cooperativeness do not play a role in maintaining authenticity. In Study 2 (n = 174) we analyzed the relationship between authenticity and the basic personality traits, measured by the Big-Five Factor Markers (Goldberg, 1992; adapted by G. Knyazev et al., 2010). It was found that authenticity is strongly conditioned by emotional stability (low Neuroticism), while self-alienation is provoked by high Neuroticism and low Extraversion and Consciousness. The relatively weak predictive ability of character and temperament traitstowards to authenticity confirms the assumption that authenticity should be considered as an independent and systemic personal trait.
