Background and study aims
Many patients with alcohol problems wish to reduce their drinking without abstaining totally. It is unclear whether it would be beneficial for these patients to start treatment with a month of abstinence. The aim of this study is to test whether a month of abstinence before treatment with an aim of controlled drinking results in better treatment outcomes.

Who can participate?
Patients aged over 18 years with alcohol dependence seeking treatment with a goal of controlled drinking

What does the study involve?
Participants are randomly allocated to 1 month of initial abstinence or to treatment as usual without such initial abstinence. All participants have a treatment goal of controlled drinking. They are offered the same treatment options: cognitive behavioural therapy (CBT) combined with pharmacological treatment.

What are the possible benefits and risks of participating?
One month of sobriety may be beneficial for health. Both treatments are likely to reduce alcohol consumption. The risks of participating are small as participants are alcohol-dependent with long-standing heavy drinking.
There is now good evidence that treatment aiming for controlled drinking, as opposed to abstinence, has good effects for persons with mild to moderate dependence severity, while persons with severe dependence are recommended abstinence. There are however several good reasons to abstain from alcohol for a period for this group as well. There is evidence that a month of sobriety is beneficial for mental, cardiovascular and metabolic health, after 1 and 6 months of follow-up. These studies however have been performed with moderate drinkers, where dependence has been an exclusion criterion. What the outcomes are for alcohol-dependent persons with higher levels of consumption has not been investigated. Even when the treatment aim is controlled drinking, an initial month of abstinence is frequently recommended. The assumption here is that the toxic effects of alcohol, which often manifest in high levels of craving, are reduced after a month of sobriety, and that this improves the prerequisites for the following treatment. This seems reasonable for persons with long-standing heavy drinking. Whether it also applies for the larger group with mild to moderate dependence has not been studied however.

Ethics approval(s)Approved 27/05/2021, The Swedish Ethical Review Authority (Etikprövningsmyndigheten, Box 2110, 75002 Uppsala, Sweden; +46 (0)10 475 08 00; registrator@etikprovning.se), ref: 2021-01959

InterventionAll study participants have a treatment goal of controlled drinking. They are offered the same treatment options: cognitive behavioural therapy (CBT) combined with pharmacological treatment. In addition to this, they will be randomized to either start their treatment with 1 month of abstinence or start with controlled drinking treatment right away.

Randomisation is done through computer-generated randomization in blocks of 10; allocation 1:1. Randomisation is performed for each inclusion, where the study participant is given a study ID which conforms to the number of inclusion. The allocation is unknown to the study coordinator and other study staff up until the point of study inclusion and the start of treatment.
Intervention typeBehavioural
Primary outcome measureAlcohol consumption measured by the Timeline Follow Back method, where drinks per week can be calculated, at baseline, 1, 6 and 12 months
Secondary outcome measuresHeavy drinking days measured by the Timeline Follow Back method, where the number of days per week with heavy drinking, defined as 5 or more Swedish standard drinks for men and 4 or more for women can be calculated, at baseline, 1, 6 and 12 months
Overall study start date01/01/2021
Completion date31/12/2025
