Brief summary
There is a high rate of psychological comorbidity in people suffering from alcohol dependence. There is a need for an effective integrated treatment for alcohol dependence and comorbid anxiety or depression. This study will test the efficacy of a novel integrated intervention for comorbid alcohol dependence and anxiety or mood disorder.
Detailed description
In summary, the specific aims of this project are: 1. To assess the effectiveness of a novel stepped care intervention for alcohol dependent patients with co-morbid anxiety and/or depression compared to usual treatment for alcohol dependence in promoting abstinence from alcohol and increased quality of life and in reducing symptoms of anxiety and depression. 2. To describe important factors relating to the maintenance of alcohol-related psychiatric comorbidity. Step 1: All subjects will complete 12 weeks of pharmacotherapy (n = 120) on naltexone (50 mg, 1 tablet daily), acamprosate (333 mg, 2 tablets 3 times daily, reduced to 4/day for women \<65kg), or a combination of the two. After a 3 week stabilization period, subjects will undergo complete formal assessment for anxiety and depression. Those subjects with a diagnosis of anxiety or depressive disorder regardless of drinking outcome will be offered the next step of care and followed up at 12-16 weeks. Step 2: Subjects to undergo the next step of care (n = 30 per group, 60 in total) will be randomized by referring to the consecutively assigned subject identification number to a matched numbered envelope containing a random assignment card. Randomization will be stratified according to concomitant SSRI use. The treatment groups will be: 1. Intervention for comorbid anxiety or depression, and 2. Usual counseling care.
Interventions
BEHAVIORALIntegrated care
Intervention for co-morbid alcohol dependence and anxiety or mood disorder. Trained therapists will deliver specific Cognitive Behavioural Therapy based upon interventions that have been supported by randomised controlled trials for alcohol use, anxiety, and depressive disorders.
BEHAVIORALUsual care
Counselling for all subjects will continue in accord with standard practice. Currently, programs of brief individualized motivation enhancement therapy (feedback of assessment findings, reinforcement, empathy, client's own motivation) are available.
