Drug addiction is a major concern in terms of both health and social security issues world-wide. Recently, adolescent crimes related to drug addiction have increased more than other types of juvenile delinquency and a considerable proportion of these crimes include murder, assault, and other violent behavior. This study explored the association between drug addiction and aggressive behavior of adolescents. The Reactive Proactive Aggression Questionnaire and Negative Mood Regulation Scale were used to compare the differences between adolescents with drug abuse (experimental group) and normal adolescents (control group). The Taylor Aggression Task (TAP), combined with measurement of ERPs, was used to manipulate the proportion of task-related wins and losses and the strength of punishment following a loss to elicit aggressive behavior and negative emotions. The kind of social interaction in this task was used to investigate the differences between the two groups in inhibitory control and emotions related to the regulation of aggressive behavior.
The results of the questionnaires showed that the reactive scores, the proactive scores, and reactive proactive scores of the experimental group were significantly higher than those of the control group. The scores from the negative mood regulation scale in the experimental group were lower than those of the control group. The behavioral data from the TAP showed that both the first trial and the mean punishment scores in the experiment group were significantly higher than those of the control group. ERP data showed that the decision related negativity (DRN) amplitude of the decision phase, indicative of inhibitory control, in the experimental group was lower than that of the control group. No difference in the feedback related negativity (FRN) in the result phase was found between the two groups. Adolescents with drug addiction showed a higher level of aggressive behavior than the normal adolescents, and this higher aggressive behavior may be associated with poor negative emotion regulation and poor inhibitory control. Drug addiction seems to be associated with a much worse inhibitory capacity of young people, and this may lead to highly aggressive behavior.
