title: Predictors of self-help group attendance in cocaine dependent patients.
abstract: OBJECTIVE
  While referral to self-help groups for patients dependent on drugs other than alcohol has become widespread in the substance abuse treatment field, little is known about the characteristics of people who attend these groups. This study examines particular sociodemographic and clinical characteristics as possible predictors of attendance at self-help groups in the National Institute on Drug Abuse Collaborative Cocaine Treatment Study.
  
  
  METHODS
  A multicenter study randomly assigned 487 patients (76.8% men) to one of four psychosocial treatments for cocaine dependence. Patients were treated for 24 weeks. Among other measures, the Weekly Self-Help Questionnaire was administered each week and completed, at least once, by 411 subjects.
  
  
  RESULTS
  Approximately two thirds of the patients attended one or more self-help meetings during the 24-week period. Patients initially more likely to attend self-help groups frequently were those who were unemployed, had no religious preference, had more severe baseline drug use and reported treatment for prior substance-related problems. Patients with more severe baseline drug use and those who previously received treatment for substance-related problems were more likely to maintain frequent attendance throughout the study period. Only severity of baseline drug use predicted more frequent attendance during Month 6, although there was a trend in Month 6 favoring more frequent attendance by women. These findings remained significant when treatment condition was added to the models.
  
  
  CONCLUSIONS
  Although these findings are consistent with past research on alcohol dependent individuals, they challenge popular clinical notions about the types of people who attend self-help groups. These findings demonstrate that self-help groups can appeal to a wide variety of cocaine dependent patients.
