Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Distress intolerant cannabis users were randomized to a computerized distress intolerance intervention or a control intervention. Primary and secondary outcomes consist of the treatment target, cannabis use-related behavior, and theoretically-relevant neurophysiological processes (i.e., cannabis cue reactivity, response inhibition).

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

At the end of the baseline assessment, the participant was randomized to the Computerized Distress Intolerance Intervention condition or the Computerized Healthy Behaviors condition. Participants in each condition attended two 1-hour intervention sessions followed by a post-treatment assessment. Follow-up assessments were conducted one-month and four-months after the post-treatment assessment.

Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Participants Outcome Assessors

Participants were blind to whether they were in the experimental (Distress Intolerance Intervention) or control (Healthy Behaviors Intervention) condition. All outcome measures were self-report except for the four-month follow-up Cannabis Use Diagnostic interview which was conducted by an interviewer blind to the participant's treatment condition.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Computerized Distress Intolerance Intervention

Two, 1-hour computerized sessions that include psychoeducation about emotional avoidance, idiographic emotional exposure, and construction of idiographic implementation intentions to practice distress tolerance skills outside of session.

Group Type EXPERIMENTAL

Computerized Distress Intolerance Intervention

Intervention Type BEHAVIORAL

Computerized Healthy Behaviors Intervention

Two, 1-hour computerized sessions that focus on psychoeducation about the importance of a healthy lifestyle.
