Alcoholism has been studied in adults and found to share obsessive-compulsive characteristics. The Yale-Brown Obsessive Compulsive Scale (YBOC) was used to quantify the measurements of this disorder. This study adapted the YBOC for use with adolescents/young adults in an attempt to measure the "craving" expressed as obsessive and compulsive phenomenon. The primary findings show that the obsessive compulsive dimensions of alcohol cravings, as described in adult populations, also exist in adolescent/young adults. The Adolescent Obsessive Compulsive Drinking Scale (A-OCDS) was developed utilizing idioms and language typical for the 17-20 age group. Various quantitative evaluations proved that the Interference and Irresistibility sub-scales were the primary dimensions causing the obsessive behavior. This study begins to address this aspect of adolescent substance abuse utilizing a tool that is easy to administer. Because of the ease of use, although not a diagnostic instrument, the A-OCDS may be useful for identifying problem drinking in adolescents as well as detecting impairment in function related to drinking.
