NCT07033416

Brief Summary

The goal of this clinical trial is to investigate if the intervention "Approach Bias Modification" (ABM) can low cocaine craving in people with Cocaine Use Disorder (CUD). The main question this clinical trial aims to answer is how many days participants can be in abstinence from cocaine after 4 ABM sessions. ABM is a computerised training aiming to train the participants to:

  • avoid drug-related images by pushing a joystick which causes the image to disappear;
  • approach positive images by pulling a joystick which causes the image to expand. Researchers will compare participants treated with ABM to those who receive Treatment As Usual (TAU) condition to see if ABM training for CUD is more effective in increasing the number of abstinent days.
  • Participants will attend 1 ABM session per week for a total of 4 sessions, each lasting 15 minutes.
  • Both cocaine and non-cocaine positive images relative to the subjective values or interests (i.e. effects, sport, music, nature, work, etc.) are presented to the participant, in portrait or landscape orientation.
  • Participants are instructed to push the joystick if the image is portrait-oriented (cocaine-related images) or to pull the joystick if it is landscape-oriented (positive images).
  • At 1 and 3-month-follow up, participants will complete self-report questionnaires to measure abstinence days and describe the effect of ABM on cocaine use, dependence symptoms, and approach bias.

Outcome Measures

Primary Outcomes (1)

  • Abstinence days from cocaine after 4 Approach Bias Modification (ABM) training sessions

    Abstinence days from cocaine measured by urine analysis and a self-report questionnaire (Timeline Follow-Back, TLFB) measuring frequency and quantity of cocaine use and route of administration.

    Urine analysis from enrollment to the end of treatment twice a week,in the first three weeks. TLFB at 1 and 3 months after the end of training.

Secondary Outcomes (5)

  • Operationalisation of continuous abstinence in participants trained with ABM, relative to TAU.

    at 1 and 3 months after the end of training.

  • Operationalisation of continuous abstinence in participants trained with ABM, relative to TAU

    at 1 and 3 months after the end of training

  • Operationalisation of continuous abstinence in participants trained with ABM, relative to TAU.

    at 1 and 3 months after the end of training

  • Operationalisation of continuous abstinence in participants trained with ABM, relative to TAU.

    at 1 month after the end of training

  • Operationalisation of continuous abstinence in participants trained with ABM, relative to TAU.

    at 1 month after the end of training

Interventions

ABM is a computerised training aiming to train the participants to avoid drug-related images (by pushing a joystick which causes the image to disappear) and approach positive images (by pulling a joystick which causes the image to expand). Each training session lasts 15 minutes and it takes place once per week for 4 weeks.

ABM+TAU

Participants receiving TAU are not trained to avoid drug-related images and approach positive images.
