Final answer:
Prevention programs designed to reduce reactive aggression generally lead to a decrease in aggressive behavior, not an increase or reinforcement of such tendencies.
Step-by-step explanation:
Researchers have found that prevention programs designed to reduce reactive aggression typically aim to decrease aggressive behavior. Such programs often incorporate strategies to promote social skills, problem-solving, and emotional regulation, which serve to mitigate aggressive tendencies and reduce overall aggression in individuals and groups. This is in contrast with concerns that have been raised about exposure to violent media or video games, which some studies suggest may be correlated with an increase in aggressive thoughts and behaviors, particularly in children. The American Psychological Association and others have identified a link between violent games and an uptick in aggression, yet not necessarily a causation for criminal violence. Prevention programs, especially when implemented in early childhood, have shown effectiveness by increasing the costs of aggressive behavior and improving labor force outcomes, which correlate with a significant reduction in crime rates.
