Abstract
A treatment method which combines thought-stopping and a program of self-reinforcement is described as it was applied to a case of mild depression. The use of thought-stopping significantly decreased the patient's level of negative self-statements while the use of operant methods substantially increased positive self-statements. However, due to the uncontrolled nature of this case study, alternate hypotheses could not be ruled out. Therefore, the present results should be interpreted with appropriate caution.
