Sponsor's own description
Alcohol is the most harmful psychoactive substance in terms of overall damage. Although abstinence remains the objective of most pharmacological and non-pharmacological approaches addressing alcohol use disorder (AUD), new therapeutic objectives of reduced alcohol intake and controlled-drinking have emerged. ETHER ("Education THEérapeutique pour la Réduction des dommages en alcoologie" or therapeutic education for the reduction of alcohol-related harms) is an ongoing, multicentre, community-based mixed-methods study, which aims to evaluate the innovative therapeutic patient education (TPE) programme named "Choizitaconso". This programme teaches psychosocial skills to people with alcohol use disorder (PWAUD), to help them (re)establish controlled drinking and reduce harms. The evaluation of the programme will rely on a sequential explanatory design, where the qualitative study (16 semi-structured interviews) will assist in explaining and interpreting the findings of the controlled before-and-after quantitative study.
