Background. The concept of the Light Triad as the direct opposite of the Dark Triad, was developed to describe a healthy, prosperous personality and is operationalized in the Light Triad Scale (LTS), which measures three “light” personality traits: faith in humanity, or belief in the fundamental nature of human goodness; humanism, or belief in the worth and dignity of each person; and Kantianism, or treating people as self-valuable individuals. The original LTS is psychometrically sound and widely used for scientific and practical purposes. Objective. The aim of this study was to pilot and analyze the preliminary psychometric properties of the Russian version of the LTS. Methods. The participants (n = 300; aged 16 to 56) completed the Russian version of the LTS and instruments measuring subjective happiness, subjective vitality, Dark Triad and Big Five traits. Results. Confirmatory factor analysis, after excluding items with weak factor loadings, revealed a three-factor structure assessing the Light Triad. The LTS scales had marginal internal reliability, ranging from 0.588 to 0.631, and were statistically significantly positively related to extraversion, conscientiousness, agreeableness, openness, subjective happiness, and subjective vitality, and negatively associated with neuroticism, Machiavellianism, and psychopathy. Conclusion. Preliminary psychometric properties of the Russian LTS showed its factorial and convergent validity. The Russian version of the LTS can be recommend as a diagnostic instrument for assessing faith in humanity, humanism, and Kantianism as traits of the Light Triad.
