Cognitive Bias Modification - Methamphetamine
The methamphetamine approach-avoidance training (MAAT) trial.
Relapse after methamphetamine rehabilitation treatment is common. A possible reason for this is that people with methamphetamine use disorder develop “approach bias”, an automatic, impulsive tendency to approach or seek methamphetamine in response to signals in the environment (e.g., images, smells, etc.) that have become strongly associated with methamphetamine. Earlier research on alcohol dependence has shown that computerised approach bias modification (ABM) training can help reduce the likelihood of relapse after people leave treatment. In an earlier pilot study, we had promising findings suggesting that ABM might help in reducing relapse to methamphetamine following discharge from treatment. We are now running a randomised controlled trial of ABM during methamphetamine treatment at 3 rehabilitation services: Albert Road Clinic, Malvern Private Hospital, and Wellington House to determine its effectiveness.
The methamphetamine approach-avoidance training (MAAT) trial tests whether 6 sessions of “brain-training”, delivered while clients are attending residential rehabilitation treatment, helps reduce cravings and prevent relapse after they leave the rehabilitation service. The ABM training involves repeatedly practising the avoidance of methamphetamine images displayed on a laptop and the approaching of positive images. We are using a randomised controlled trial (RCT) to compare the effectiveness of the ABM training task, to another similar task that does not alter approach bias.
