Abstract:
The frequency of alcohol use among a subject population of 28 male and 60 female college students was assessed using the Student Alcohol and Drug Use Survey (STADUS). Data were also collected on personality traits as measured by the Sensation Seeking Scale V (SSSV) and the Eysenck Personality Questionnaire (EPQ). Finally, three biochemical variables were assessed: monoamine oxidase (MAO) activity, dopamine beta hydroxylase (DBH) activity, and testosterone levels. Among males, high SSSV scores, high testosterone levels, and low MAO activity contributed to the variance in alcohol use, whereas among females, a significant proportion of the variability in alcohol use was accounted for by high SSSV scores, high DBH activity, and younger age.
