Since the development of the Lubin Depression Adjective Check Lists (DACL) in 1965, researchers have used this instrument in many empirical and clinical studies. Scores on the DACL have correlated with other measures of depression and have also been related to personal characteristics of depressed individuals. The DACL has been used in studies to assess depression across time in relation to physical and psychological conditions such as insomnia, and in studies of premenstrual mood change and mood change during pregnancy and following childbirth. Studies on the effects of drugs or medical treatments have used the DACL to investigate cyclic hormonal levels, response to electroconvulsive shock, alcohol withdrawal, drug intake, pain perception, and exertion. Evaluation studies of therapy or behavioral interventions for the treatment of depression often use the DACL. Theoretical investigations of anger and learned helplessness have also used the DACL. Ease of administration and the benefits of matched repeated lists have provided investigators with a simple method for assessing depression across time and in relation to a number of concomitant events.
