Some theories suggest that this connection is due to a learning process where individuals may adopt the attitudes, beliefs, and behaviors of those with whom they have significant interactions, such as friends. While individuals may be susceptible to learning anti-social behavior from peers, it is unclear if certain personality characteristics may affect this relationship. The purpose of this study is to determine if differences in specific personality characteristics, such as self-esteem, introversion and extroversion, can have a moderating effect on the pressures to participate in the use of drugs and alcohol that are projected on to individuals during their adolescent years. The findings of the current study can lead to new pathways in substance use prevention and personality assessment in conjunction with risk assessment for juveniles during their middle and high school years. v" AN ANALYSIS OF PERSONALITY AND THE EFFECT OF PEER INFLEUCNCE ON DEVIANT BEHAVIOR DURING ADOLESCENCE Tables
