A randomized controlled trial of brief cognitive–behavioral interventions for cannabis use disorder
Open accessAbstract
The increasing demand for treatment for cannabis dependence in Australia and internationally has led to the identification of significant gaps in knowledge of effective interventions. A randomized controlled trial of brief cognitive-behavioral interventions (CBT) for cannabis dependence was undertaken to address this issue. A total of 229 participants were assessed and randomly assigned to either a six-session CBT program (6CBT), a single-session CBT intervention (1CBT), or a delayed-treatment control (DTC) group. Participants were assisted in acquiring skills to promote cannabis cessation and maintenance of abstinence. Participants were followed-up a median of 237 days after last attendance. Participants in the treatment groups reported better treatment outcomes than the DTC group. They were more likely to report abstinence, were significantly less concerned about their control over cannabis use, and reported significantly fewer cannabis-related problems than those in the DTC group. Those in the 6CBT group also reported more significantly reduced levels of cannabis consumption than the DTC group. While the therapist variable had no effect on any outcome, a secondary analysis of the 6CBT and 1CBT groups showed that treatment compliance was significantly associated with decreased dependence and cannabis-related problems. This study supports the attractiveness and effectiveness of individual CBT interventions for cannabis use disorders and the need for multisite replication trials.

“Best-practice evidence suggests that the most effective treatment response for cannabis-dependent users is a 'brief intervention' involving six sessions of cognitive behavioural therapy, yet this is not currently provided in Portugal (see, e.g.Copeland et al. 2001).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
