Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention to be evaluated in this study (i.e. the alcohol intervention program) is based on an adapted version of the Alcohol Skills Training Program (ASTP), an evidence-based intervention developed for college students in the USA by Professor Alan Marlatt and his colleagues. The Alcohol Intervention Program (AIP) consists of 5, 2-hour group sessions held once weekly for 5 weeks, with a focus on learning controlled drinking techniques in high-risk situations. Total duration of the intervention: 5 weeks. Other components of the program are: learning information regarding alcohol's effects, Blood Alcohol Level (BAL) discrimination training, limit setting, the role of myths about alcohol (outcome expectancies) and social and normative cues for drinking, including mindfulness strategies for counteracting these influences. The program requires facilitation by a qualified therapist and is a closed group program generally consisting of 10 participants. An additional two sessions of Therapeutic Telephone Counselling (TTC) are delivered fortnightly once a person leaves (exits) the Therapeutic Community (TC).

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Approximately 150 (75 in each group) recovering drug users who provided informed consent were recruited for participation in this study from Odyssey House Victoria drug rehabilitation services (inpatient) and Windana Society (drug rehabilitation service in Victoria). Allocation involved contacting the holder of the allocation schedule who was at a central adminstration site within each TC. Participation was voluntary, free of charge and all clients are able to withdraw at any stage. In order to ensure comparability between groups, randomisation occurred after recruitment, selection criteria, and baseline assessments had been conducted approximately 2 weeks into residential treatment. At baseline all eligible participants were assigned a numeric code. An independent researcher (not involved in the study) randomised the participants into the treatment or control groups using computer-based random number generation.
