The African-American replication sample included 972 African-Americans (356 males, 616 females) all screened with the Beck Depression Inventory (BDI) (Beck et al., 1961; Viinamaki et al., 2004)(Viinamaki et al., 2004). Study design, ascertainment and rating protocols have been described elsewhere in more detail (Binder et al., 2008). A BDI score of 16 or greater was considered indicative of current depression.
