Overlapping addictions and self-esteem among college men and women.

To examine whether there is a tendency for individuals to be multiply addicted, overlapping addictions to common substances (alcohol, caffeine, chocolate, cigarettes) and activities (exercise, gambling, Internet use, television, video games) were studied in 129 college men and women. Contrary to previous research, moderate to large correlations were found, both within and between substances and activities. Self-esteem was positively related to exercise but unrelated to the remaining addictions. Several gender differences in addictive tendencies were also revealed: Men scored higher than women on addiction to alcohol, cigarettes, gambling, television, and Internet use, but women scored higher on caffeine and chocolate. The results have implications for theories of addiction and suggest new directions for the study of addiction among normally functioning young adults.
