Background: Numerous research endeavors have explored how well the SD3 applies across diverse cultural settings, spanning from Portugal and Serbia to Delhi, the UK, and Kolkata. This study, with a particular focus on validating the tool in the Indian context, contributes to the existing body of research and expands upon the limited studies conducted in India. Materials and methods: To gather data for this research, 652 secondary school students from West Bengal attending coeducational institutions, aged between 14 and 18, were randomly chosen. Participants were selected based on a predefined factor structure. The initial stage involved cleaning the data obtained from the research tool and transferring it to SPSS version 23.0, a user-friendly statistical software program. Results: Analyzing a total of twenty-six items, the study identified three distinct factors: "Machiavellianism," "Narcissism," and "Psychopathy," consistent with the original SD3 scale. The findings suggest that the Indian adaptation of the scale is both valid and reliable for assessing Dark Personalities among adolescents aged 14 to 18. Conclusion: The psychometric analysis reveals that the current scale possesses sufficient qualities to evaluate dark personality traits in Indian teenagers. This scale holds promise as a significant tool for gauging the prevalence and underlying mechanisms of psychosocial factors contributing to dark personality traits among adolescents in school settings.
