How Spiteful Are We? Validation of the Spitefulness Scale in Spaniards.

Spitefulness has been defined as the willingness to cause some kind of harm to other people, even if this action does not bring any benefit and causes harm to herself. Given its relationship with a multitude of antisocial behaviors, interest in studying this trait has been growing and it was in 2014 when the first scale to measure it was validated: the Spitefulness Scale. This study aimed to examine the psychometric properties of its Spanish version. In a sample of 758 participants (M = 31.44; SD = 12.91; 72.80% female), the Spitefulness Scale, the Short Dark Triad, the Assessment of Sadistic Personality, the HEXACO-60, and the Global Assessment of Internet Trolling were administered. Results showed the unidimensionality of the scale, adequate reliability indices, and construct validity, evidenced by positive relationships with the Dark Tetrad traits and trolling behavior. Additionally, the analysis revealed significant gender differences, with males scoring higher on spitefulness. This Spanish validation allows us to establish a solid basis for cross-cultural comparisons. Understanding this trait, considered like the Dark Tetrad traits an antagonistic personality trait, has important implications for understanding the interpersonal and social dynamics. Given that spitefulness is closely related to aggressive behaviors, it is essential to study it to understand the underlying mechanisms of aggression and hostility in social interactions.
