 To date, after an extensive review of the literature using MEDLINE, Pub Med, ERIC, Web of Science, Science Direct and PsycINFO, no studies was found on the use of SMS text messages as an intervention to address abstinence amongst alcohol dependent subjects who are co-morbid for a depressive disorder. Thus, the investigators seek to determine if text messaging is a useful and effective strategy to help maintain abstinence, improve adherence with medication and ultimately promote mental stability in depressed patients discharged from an in-patient dual diagnosis programme. The investigators hypothesize that, daily supportivereminder SMS text messages to depressed patients discharged from an in-patient dual diagnosis programme would increase alcohol abstinence rates , improve medication adherence rates and improve the overall mental well being of patients compared with those receiving treatment as usual.
