Treatment for Affect Dimensions

The purpose of this study is to evaluate the efficacy and targets of Positive Affect Treatment, a psychotherapy specifically aimed at enhancing reward sensitivity in individuals with low positive affect (a core feature of anhedonia) in the context of depression or anxiety. Target enrollment is 68 male and female participants with low positive affect and depression or anxiety and impaired functioning, between the ages of 18 and 65 years, who will be randomized to either Positive Affect Treatment or Negative Affect Treatment (designed to reduce threat sensitivity). Participants will complete laboratory tests, psychiatric assessments, and self-report questionnaires as part of the study. The total length of participation is around 4 months.
