title: Does psychosocial treatment enhance the efficacy of acamprosate in patients with alcohol problems?
abstract: OBJECTIVE
  Acamprosate in combination with psychosocial treatment has been shown to be effective for the treatment of alcohol dependence. The goal of the present study was to determine whether the addition of psychosocial intervention to the medical prescription of acamprosate contributes to treatment outcome.
  
  
  METHODS
  Patients (n = 248) meeting DSM-IV criteria for alcohol dependence or abuse were recruited in 14 outpatient treatment centres and randomized into one of three treatment conditions: acamprosate; acamprosate plus minimal intervention aimed at motivational enhancement (3-weekly sessions of 20 min); and acamprosate plus brief cognitive behavioural therapy (7-weekly sessions of 60 min). Acamprosate was prescribed for 28 weeks, medically monitored by a physician on six occasions lasting 10 min. Drinking behaviour, medication compliance and psychological distress were assessed throughout the treatment period. Follow-up assessment was undertaken 6 months after termination of pharmacological treatment.
  
  
  RESULTS
  Of 241 patients with intention to treat (ITT), 114 (47.3%) remained in treatment for the full 28 weeks; 169 of the ITT population (70.1%) were seen for follow-up. No statistically significant differences were found between treatment groups for any of the drinking outcomes either at the end of the 28 weeks of treatment or at 6-month follow-up. There were no statistically significant differences in medication compliance, drop-out rates, or psychological distress. However, a significant interaction effect was observed between treatment centre and treatment group, indicating that brief interventions were differentially effective in different treatment centres.
  
  
  CONCLUSIONS
  A clear supplemental value of minimal and brief psychosocial interventions to the prescription of acamprosate was not demonstrated. The widely held belief that pharmacotherapy for alcohol dependence should always be combined with psychosocial intervention is debatable and merits further research.
