Interview data from 7,359 adults 18 years of age and over who met the DSM-IV criteria for alcohol abuse or dependence at some point during their lives revealed that 23.0% of the men and 15.1% of the women ever received treatment for alcohol problems. The median interval from onset of disorder to first treatment was between 2 and 3 years longer for men than women. This difference did not result from women being more likely than men to initiate treatment shortly after onset of an alcohol use disorder, but rather from men being more likely than women to initiate treatment in the period well after onset. Excluding treatment initiated prior to the clinical onset of the disorders or after cessation of drinking, men's and women's cumulative conditional probabilities of having initiated treatment by 30 years after onset of alcohol abuse or dependence were .424 and .356, respectively. Within the first 8 years after onset of abuse or dependence, men's and women's probabilities of initiating treatment were about the same, but men were 13% to 20% more likely to initiate treatment in the period from 8 to 25 years after onset Use of proportional hazards models to adjust for factors including sociodemographic characteristics, prior consumption, severity of disorder, and comorbid drug use and depression revealed that men's and women's likelihoods of ever having received treatment did not differ for the most severely affected, those with 20 or more symptoms of abuse or dependence. Among those less severely affected, the male-re-female ratio in the likelihood of treatment declined with severity from 1.75 (1 symptom) to 1.24 (15 symptoms).
