Twenty-two (43.1%) of the 51 participants relapsed during the period of study participation. Initial analyses within gender suggested that, excluding the trauma measures, relapsers did not differ significantly from abstainers on any of the demographic or clinical characteristics assessed, with the exception of male abstainers being marginally older than male relapsers and female relapsers having marginally fewer days of alcohol abstinence than female abstainers (see Table 1, upper panels). Thus, subsequent logistic regression analyses of trauma measures as predictors of relapse covaried for age in men and for days of alcohol abstinence in women.
