Factors Predicting Outcome in Group Treatment of Alcohol Use Disorders (AUDs)

Condition(s) studied

Study summary

Harmful alcohol use is a global risk factor for disease, injuries and death. Research on treatment of Alcohol use disorders (AUDs) indicates that different treatment modalities are equally effective, but also that a large group of patients do not change their drinking pattern despite being in treatment. It is assumed that it is not random who benefits from treatment. Thirty to forty percent of outcome variance in treatment is probably explained by patient factors, and we need more knowledge on how different patient factors moderate treatment effects.

Further, clinicians also need more knowledge about selecting patients to different therapies. The present study will investigate how patient factors predict outcome in group treatment of AUDs, and what predicts positive treatment outcomes over time. The study is designed as a quasi-experimental, multi-centre, follow-up study. Patients will be included from Vestfold Hospital Trust, Borgestadklinikken, Blue Cross Clinic, Behandlingssenteret Eina, Blue Cross Clinic and A-senteret, Oslo, Church City Mission. The Project will provide more knowledge about patients seeking treatment for AUDs, and specifically how patient factors predict outcome in group treatment. These results will in turn lead to better selection of treatment modalities, and patients will receive a more effective treatment earlier on.

Main aims: 1) How do patient factors predict outcome in group treatment of alcohol use disorders (AUDs)? 2) Do positive treatment outcomes last over time? Specifically, do the following factors: a) psychiatric comorbidity b) severity of alcohol use pre-treatment c) personality disorders and d) cognitive impairments predict 1) completion of group treatment and 2) positive outcome after 1 year. As an additional aim, we will investigate if the Montreal Cognitive Assessment test (MoCa) is feasible as a brief screening instrument for mild cognitive impairments for AUD patients.

Eligibility

Primary outcome measure(s)

• Successful treatment completion — At treatment completion assessed up to 14 days
  Operationalized as percentage of participation in therapeutic activities
• Change in alcohol consumption — Assessed 1 year after treatment completion
  Change in alcohol consumption after 1 year. Measured with Alcohol use disorders identification test (AUDIT) and one additional question of number of alcohol units consumed during the last week.
• Change in alcohol consumption — Assessed 3 years after treatment completion
  Change in alcohol consumption after 3 years. Measured with Alcohol use disorders identification test (AUDIT), and one additional question of number of alcohol units consumed during the last week.
