Descriptive statistics for key study variables for the marriage and divorce analytic samples are presented in Table 1. Representativeness analyses of the marriage and divorce analytic samples are summarized in Supplement, section S1. The divorce analytic sample was derived from the marriage analytic sample, as marriage is a prerequisite for divorce. Thus, in the EA and AA samples respectively, 283 and 521 participants were excluded as they were never married. Further, 283 and 110 additional participants in the EA and AA marital analytic samples, respectively, were removed to form the divorce analytic sample because they had not yet been married long enough to pass through the initial risk period of divorce (i.e., less than 3 years without divorcing). Differences between the marriage and divorce samples as a function of AUD and comorbid disorders are summarized in the Supplement, section S1.
