Computer-Mediated Versus Face-to-Face Motivational-Type Interviews

Description

This study looks at whether in-person and computer-based motivational type interviews lead to the same kind of language and behavior change in young adults when they talk about their marijuana use. Researchers compared how much participants talked about wanting to change their level of marijuana use (change talk) or maintain their level of marijuana use (sustain talk) during each type of interview. Researchers investigated if change talk and sustain talk predicted who continued to use or not use marijuana. All participants completed: * A survey assessing their frequency of marijuana use. * A brief motivational type interview, either a face-to-face-motivational type interview or computer-mediated motivational type interview. * A two-month follow-up survey, again assessing their level of marijuana use.

Eligibility Criteria

  • * A brief eligibility questionnaire assessed each respondent's age, previous marijuana use, and ambivalence about their marijuana use during the year preceding the study. Sample ambivalence items included: "During the past year I've had mixed emotions about my level of marijuana use or nonuse," and "How much have you thought about changing your marijuana use or nonuse during the past year?" Responses options ranged from 0 ("not at all") to 5 ("medium amount") to 10 ("a lot"). Respondents who were 18-29 years of age and reported at least a "medium amount" of ambivalence in response to 2 or more ambivalence questions were eligible to participate in the study. Three types of adults were recruited: non-marijuana users, occasional marijuana users, and frequent marijuana users. Non-marijuana users were defined as individuals who reported no history of marijuana use in their lifetime. Occasional marijuana users were defined as individuals who used marijuana 1-5 times during the 2 months preceding the study but fewer than 24 times during the year preceding the study. Frequent marijuana users were defined as individuals who used marijuana more than 7 times during the 2 months preceding the study and more than 24 times during the year preceding the study.
  • * We excluded participants who did not meet the above criteria.
