Community Reinforcement and Family Training (CRAFT)

Study Overview
=================
Brief Summary
-----------------
The present study is dedicated to empowering individuals close to an addicted person (i.e. concerned significant others, CSOs) to create changes in their family environment: changes that increase the likelihood of the addicted person seeking treatment. The Danish National Clinical Guideline for the treatment of alcohol dependence recommends that alcohol treatment centers offer interventions aimed at CSOs, providing them with the support and empowerment that will enable them to motivate the problem drinker to enter treatment. In the US, the Community Reinforcement and Family Training (CRAFT) intervention has been shown to offer the most effective support to CSOs. CRAFT has consistently demonstrated a two to three times' higher impact on getting individual with an alcohol use disorder (AUD) to attend treatment, compared to other kinds of interventions. Studies of the intervention so far have, however, been small, and the format used in the delivery of CRAFT has not been fully investigated. The aim of the present cluster randomized controlled trial is to implement and investigate CRAFT in a Danish context and with sufficient sample size. Consecutive CSOs will through cluster randomization be randomized to receive either CRAFT in a group format, CRAFT in an individual format, or a control condition, consisting of self-help material only. The primary outcome of the study will be the rate of individuals with AUD entering treatment following the intervention targeted at the CSOs within three months from its initiation. Data will be collected from all CSOs at baseline, three, and six months after baseline.

| Experimental: Individual CRAFT<br>Individual CRAFT is offered to 135 participants and each participants are going to get 6 sessions. | Behavioral: CRAFT<br>* CRAFT is a counseling/therapist to concern significant others to get their loved one, with an alcohol use disorder, into treatment<br>|

| Experimental: Self-help materials<br>Self-help materials (control group) are going to be offered a self-help book, because it is unethically not to offer any intervention, as the CRAFT intervention in early studies have shown to be very effectful | Behavioral: CRAFT<br>* CRAFT is a counseling/therapist to concern significant others to get their loved one, with an alcohol use disorder, into treatment<br>|
