“…The state form of the DACL was developed to measure short-term depressive mood and change in depressive mood, while the more recent trait form was developed to measure more enduring or long-term depressive mood (Lubin, 1981(Lubin, , 1994. Both forms of the DACL have been used in a wide variety of investigations (Lubin, Swearngin, & Seaton, 1992), and numerous investigations of the reliability and validity of the DACL with a number of diverse subject populations have been reported (Beckingham & Lubin, 1991 ; DeSouza, Lubin, & Whitlock, 1991; Grayson, Lubin, & Whitlock, 1994;Lubin, 1981;Lubin, 1994;Lubin, Hornstra, & Dean, 1978;Lubin, McCollum, Whitlock, Thummel, Powers, & Davis, 1994;Lubin & Turnbull, 1993;Lubin, Whitlock, McCollum, Thummel, Denman, & Powers, 1994;Lubin, Whitlock, Schemmel, & Swearngin, 1993;Lubin, Whitlock, Swearngin, & Seever, 1994; Reisenmy, Lubin, Whitlock, & Penick, 1993). In these studies, both versions of the DACL have been shown to have high internal consistency and alternate form reliability.…”
