Testosterone and aggressive behavior in juvenile offenders with antisocial tendency: The mediation effect of hostile attention bias and the moderation effect of cortisol

complete mediation role in the relationship between testosterone and aggressive behavior (i.e. variability a complete mediation role in the prediction of AQCV total score, physical aggression subscale score, and anger subscale score. Peak TL-BSNEGATIVE played a complete mediation role in the prediction of verbal aggression subscale score by testosterone). (2) Cortisol moderated the relationship between testosterone and attention bias toward hostile More at a high cortisol level, attention avoidance (Peak TL-BSNEGATIVE) and variability, thereby reducing the aggression level. However, the mediation effect of attention bias toward hostile stimuli was not significant at a low cortisol level. Based on the dual-hormone hypothesis and social information processing theory, the present study examined a moderated mediating model in a sample of juvenile offenders with antisocial tendency using the perspectives of biological hormone and social information processing in aggressive behaviors. The present study revealed a potential development mechanism of aggressive behaviors in juvenile offenders and thus provides an empirical foundation for hormone-based interventions against aggressive behaviors in juvenile offenders. Finally, on the basis of the mediation and moderation effects of biological hormones on aggressive behavior, the present study indicates that increasing attention avoidance and the cortisol level for juvenile offenders with antisocial tendency might help reduce their aggressive violence.
