Research and/or Creative Works
My primary research interests are the psychopathology and treatment of adult mood disorders, including:
- cognitive-behavioral models of depression onset, maintenance, and recurrence.
- cognitive-behavioral therapy for depression.
- subtypes of recurrent depression including seasonal affective disorder (SAD) and menstrual distress.
- secondary research interests in the role of the menstrual cycle in the onset and maintenance of anxiety in women.
The Rohan Laboratory is currently conducting a 5-year randomized clinical trial, funded by the National Institute of Mental Health, in which 160 community adults with seasonal affective disorder (SAD) will be treated with either SAD-tailored cognitive-behavioral therapy (CBT-SAD) or with light therapy and followed over 2 years. This project applies the experimental therapeutics approach to determine the mechanisms through which CBT-SAD and light therapy work and to identify the best candidates for each. Consistent with NIMH’s focus on biological endpoints, we will ascertain whether theoretically-derived candidate biomarkers of each treatment’s target and effect are prescriptive of better outcomes in that treatment vs. the other.
