Computer-Mediated Versus Face-to-Face Motivational-Type Interviews
United States150 participantsStarted 2014-03
Plain-language summary
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.

Inclusion 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.
Exclusion Criteria:
* We excluded participants who did not meet the above criteria.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial compared computer-based interviews to face-to-face conversations for reducing marijuana use — since it's already completed, would my doctor be able to share or look up what the results showed about which approach actually worked better?
2The study measured marijuana use frequency at two months after the intervention — is a two-month window long enough to know whether a motivational interview approach would help me sustain changes over a longer period?
3Since this trial used a motivational-type interview rather than medication or traditional therapy, how does that compare to other evidence-based options my doctor might recommend for my situation?
4This study is listed as phase 'NA,' meaning it was more of a behavioral research study than a drug trial — does my doctor think a motivational interviewing approach, whether computer-based or in-person, is something worth trying alongside or before any other treatment?
5Given that the trial is completed, would my doctor know of any ongoing studies or available programs based on this kind of research that I could actually access right now?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
