Abstract
To estimate the reliability and validity of the state and trait versions of Set 2 (E, F, G) of the Depression Adjective Check Lists with chemically dependent adults, two independent studies were conducted. Reliabilities [internal consistency (alphas), split-half reliability, and alternate form reliability] and convergent and discriminant validities were adequate. Women's means (state: n = 49; trait: n = 41) were higher than men's (state: n = 50; trait: n = 48) on both versions, and scores on the state version were higher than on the trait version. These heterogeneous chemically dependent subjects (history of drug use and abstinence) were significantly higher on depressive affect than normal persons.
