Spiritual well-being and "dark" personality traits: Machiavellianism, narcissism, psychopathy, and sadism.

Résumé

INTRODUCTION: The study of human well-being and its contributing factors remains a central concern in psychological science. One under-researched area involves the relationship between spiritual well-being-an integrative indicator of health and life satisfaction-and "Dark Personality" traits: Machiavellianism, psychopathy, narcissism, and sadism. No prior studies have explored this relationship within the Russian population, largely due to the absence of a validated instrument for assessing spiritual well-being. The present study attempts to address this empirical void. The aim of the study was to examine the relationship between spiritual well-being and Dark Tetrad traits in a Russian-speaking sample.MATERIALS AND METHODS: The empirical sample consisted of 959 Russian-speaking participants (761 women and 198 men; M age = 38.6, SD = 14). Spiritual well-being was assessed using the . The Dark Tetrad traits were measured with the . Data analysis was conducted using R version 4.5.1 (R Foundation for Statistical Computing). Descriptive statistics, Spearman's rank correlation coefficient (), as well as univariate and multivariate linear regression analyses were applied.RESULTS: The correlational analysis supported the hypothesis of a negative association between spiritual well-being and Machiavellianism, psychopathy, narcissism, and sadism. However, univariate and multivariate regression analyses revealed more complex interactions. For the RWB subscale measured by the SWBS, analysis indicated a significant shift in the association with psychopathy: from negative ( = -0.44 [95% CI: -0.61; -0.28]) to positive ( = 0.38 [95% CI: 0.21; 0.55],
