 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 daily text messages delivered via mobile phone as an intervention to address abstinence amongst alcohol dependent subjects who are co-morbid for a depressive disorder. Thus, we 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. We 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. Patients receiving the text messages and phone calls would also report a favourable experience and an overall satisfaction with the system.
