Nine different confirmatory factor analysis (CFA) models, including CFAs with correlated traits, uniquenesses, and methods, were employed to test the factorial structure of Rosenberg's (1965) self-esteem scale in a sample of crack-cocaine drug users. The results partially support earlier research and show that (a) there exists a single global self-esteem factor underlying responses to Rosenberg scale; (b) method effects associated with item wording exist; and (c) the method effects were associated primarily with positively, rather than negatively, worded items.
