Instrument
The current study utilized a customized survey instrument to answer the research questions. Development of this questionnaire included a comprehensive literature review focusing on alcohol consumption among college students, and the Integrated Behavioral Model. Additionally, a total of six focus groups (two for abstainers, two for social drinkers, and two for high-risk drinkers) were used to elicit information to help design the survey and related items. The written questionnaire assessed the alcohol related behaviors among college students, comprised of 69 items on four pages. The questions included in this survey consisted of items related to the IBM, drinking habits, and demographics. Questions based on the IBM were developed using either a 7-point semantic differential or Likert-type scale. All of these scales were developed using the suggestions by Montano and Kasprzyk (2008).
