Short- and Long-Term Prospective Links between HEXACO Personality and Adolescent Psychopathic Traits
摘要
Psychopathic traits are strong predictors of antisocial and criminal behavior, making an understanding of their origins an important issue for personality researchers. One plausible origin for psychopathic traits is that they are a unique configuration of more general personality traits. The HEXACO model of personality appears to be strongly linked to psychopathic traits, especially with regards to Honesty-Humility. Yet longitudinal research on the links between the HEXACO and psychopathic traits have yet to be examined, particularly in adolescence which is when many personality traits become more stable. We therefore conducted a prospective study of adolescents to determine the short-term (6 months; n = 421) and long-term (3.5 years; n = 323) links between self-reported HEXACO and psychopathic traits (YPI-S). In the short-term, a path model showed Honesty-Humility emerged as the strongest predictor of total psychopathic traits and was also a significant predictor of each dimension of psychopathy: Grandiose-Manipulative (along with higher Extraversion), Callous-Unemotional (along with lower Emotionality), and Impulsive-Irresponsible (along with higher Emotionality and lower Conscientiousness). In the long-term, the links were weaker, with lower Agreeableness predicting total YPI-S scores, while Grandiose-Manipulative was again predicted by lower Honesty-Humility and higher Extraversion, Callous-Unemotional was predicted by lower Emotionality and Agreeableness, and Impulsive-Irresponsible was only predicted by lower Conscientiousness. Our findings suggest that HEXACO personality is longitudinally associated with psychopathy during adolescence, which may have implications for the clinical use of the HEXACO in understanding the stability and development of psychopathy.
