- Date Registered NTR18-sep-2015
- Secondary IDsprojectnummer 843001608 ZonMw
- Public TitleE-health attentional bias intervention in addiction
- Scientific TitleInternet-based attentional bias modification training as add-on to regular treatment in alcohol or cannabis dependent outpatients.
- ACRONYM
- hypothesisWe hypothesize that iABM patients, relative to controls, will show less addiction problems, increased health, reduced physical and psychological complaints, and reduced use of health care post-intervention and at 6 & 12 month FU Further, we hypothesize that the effects on the individual en societal level cause a decrease in societal costs that outweighs the additional costs of the iABM
- Healt Condition(s) or Problem(s) studiedAddiction, Cannabis, Alcohol
- Inclusion criteriaIn order to be eligible to participate in this study, a subject must meet all of the following criteria: individuals diagnosed with alcohol use disorder (AUD) and/or cannabis use disorder (CUD), who start GB-GGZ treatment in one of the three participating addiction treatment centres.
- Exclusion criteriaPatients showing compulsive gaming, a gambling disorder, or internet addiction will be excluded from participation because the internet delivered training task might have counterproductive effects for this group of patients. Further, patients who do not have a Personal Computer (PC), or Notebook and access to internet at home will be excluded for this study.

- Target number of participants213
- InterventionsThe iABM is a computerized intervention aimed at modifying automatically triggered attentional processes that have been shown to play a role in addiction which will be delivered at home, in multiple sessions concurrent with and for the duration of TAU.
- Primary outcomePrimary outcome parameters are changes in substance use, level of dependency and craving, and relapse-rates. Health condition, and societal costs will be primary outcome parameters to assess cost-effectiveness of this intervention.
- Secondary outcomeA secondary aim of this project is to explore which type of patients benefit most from the addition of internet-based ABM, in order to enable the most effective targeted delivery of this treatment component in the future.

- Brief summaryAddiction is characterized by high relapse numbers after successful treatment. Cognitive models of addiction suppose that the development and maintenance of addiction can be explained by an imbalance between automatic, impulsive processes and reflective, controlling processes. Research has shown that addicted individuals demonstrate a heightened automatic attention (attentional bias, AB) for ‘their’ substance. That is, their attention is automatically and unintentionally drawn towards information that is related to their addiction, and they have trouble redirecting their attention away from this information. Using computer tasks the strength of this AB can be measured. stronger AB has been associated with greater severity of addiction, poorer treatment outcomes, and increased relapse. Recently, new techniques have been developed in order to train the automatic attention away from substance information (attentional bias modification, ABM). Importantly, ABM can be effectively delivered via the Internet (iABM), which allows a low-cost, efficient delivery system for this treatment. The proposed project will investigate the (cost)effectiveness of iABM as an add-on to addiction treatment as usual (TAU) (i.e., blended therapy).
We hypothesize that iABM patients, relative to controls, will show less addiction problems, increased health, reduced physical and psychological complaints, and reduced use of health care post-intervention and at 6 & 12 month FU
Further, we hypothesize that the effects on the individual and societal level cause a decrease in societal costs that outweighs the additional costs of the iABM.
