Brief Summary:

The purpose of this study is to determine whether patient self-matching (as compared with treatment as usual by expert matching) improves quality of life, retention, and outcome for patients being treated for alcohol problems.

There are at least two good reasons for offering patients a choice when the goal is a change in their behavior. The first is that patients are likely to know what treatment works best for them. Secondly, being allowed to choose between options may increase compliance in treatment. As a randomized controlled trial, this study will compare the efficacy of patient self-matching versus treatment-as-usual expert matching.

The Self-Match Study is expected to increase knowledge on the importance of involving the alcohol dependent patient in choosing what treatment method is best for him/her instead of having experts to do that. The investigators expect to discover patient involvement as a way to improve compliance in treatment, hence preventing that patients drop out of treatment to early. If this hypothesis proves to be right, clinicians will have a viable strategy for matching treatment methods to patients, since the strategy does not demand further resources in the treatment system.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 400 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Care Provider)
Primary Purpose: Treatment
Official Title: A Randomized Controlled Study of Patients Matching Themselves to Treatment Options: The Self-Match Study
Actual Study Start Date : May 1, 2017
Actual Primary Completion Date : November 1, 2019
Estimated Study Completion Date : January 29, 2021

Arm Intervention/treatment
Experimental: Self Match
The patient must choose between the five possible treatment options.
Behavioral: Self Match
Video presentation of treatment option are shown to the patient whereafter the patient must choose between the five possible treatment options.

Active Comparator: Expert Match
The Patient is referred to treatment by standard procedure which is Expert Match based on patient data.
Behavioral: Expert Match
Referral as usual to one of five possible treatment options. The referral is based on baseline data from the patient and by the means of an algorithm, used in daily clinical praxis.

Primary Outcome Measures :
  1. Reduced amount of drinking days measured by Time Line Follow Back. [ Time Frame: 6 months after initiation of treatment. ]
    The primary endpoint analysis will be a comparison of outcomes for patients assigned to the self-match group vs. expert-match group to determine whether self-matching yields more favorable outcome than expert matching, measured by the number of excessive drinking days.

Secondary Outcome Measures :
  1. Compliance measured by proportion of patients who has completed treatment. [ Time Frame: 6 months after treatment start ]
    Data on patients who have completed treatment as planned will be gathered from treatment journal.

  2. Quality of life measured by WHO's Quality of Life scale. [ Time Frame: 6 months after treatment start. ]
    Patients reporting increase or decrease in quality of life compared to baseline.

  3. Personality traits, measured by NEO-FFI-3, influence on outcome. [ Time Frame: 6 months after treatment start. ]
    Comparison of personality traits with outcome measures.

  4. Deviation in the chosen treatment in the Self-Match group in relation to the expected expert choice. [ Time Frame: 6 months after treatment start. ]
    The algorithm score used in expert-matching will be calculated for all patients. The chosen treatment for patients in The Self-Match Group will be compared to the algorithm score to measure convergence between Self-Match and Expert-Match.
