This study seeks to extend the knowledge gained from the pilot study. A larger group of patients with alcohol use disorder and a depressive disorder will be randomly assigned to two groups. One group will receive supportive text messages for six months duration whilst the other group will receive no supportive text messages. The patients will be followed up at 3, 6, 9 and 12 months to determine which of the two groups have less alcohol and mood problems. It is anticipated that patients receiving supportive text messages will report significantly greater alcohol free days as well as significantly less relapses, hospitalizations and mood symptoms than those not receiving such messages.
