Abstract: This pilot study tested the efficacy of a
brief intervention using motivational interviewing (MI)
plus mindfulness meditation (MM) to reduce marijuana
use among young adult females. Thirty-four female
marijuana users between the ages of 18 and 29 were
randomized to either the intervention group (n = 22),
consisting of two sessions of MI-MM, or an assessment-
only control group (n = 12). The participants' marijuana
use was assessed at baseline and at 1, 2, and 3 months
posttreatment. Fixed-effects regression modeling was
used to analyze treatment effects. Participants
randomized to the intervention group were found to use
marijuana on 6.15 (z = -2.42, p = .015), 7.81 (z = -2.78, p
= .005), and 6.83 (z = -2.23, p = .026) fewer days at
Months 1, 2, and 3, respectively, than controls. Findings
from this pilot study provide preliminary evidence for the
feasibility and effectiveness of a brief MI-MM for young
adult female marijuana users.
