Session Abstract (150 words): 

With increase in health care costs, treatment funding needs to be based on both costs associated with change in health service use and increase in quality of life, not only effectiveness (Yates, 2009). As part of a clinical trial comparing light therapy (LT) and cognitive-behavioral therapy for seasonal affective disorder (CBT-SAD) over two subsequent winters, cost-effectiveness and cost-benefit analyses were performed. Patient costs (i.e., resources devoted to treatment) and outcomes (i.e., health care utilization and productivity) were monetized to determine the cost-benefit of both treatments. Patient-reported frequencies of received medical services were converted into Common Procedural Terminology (AMA, 2010), then into monetary values based on Medicaid rates. Quality-Adjusted Life Years Gained (QALYGs) were established to determine cost-effectiveness of each treatment and calculated using individual health utility scores derived from changes on the BDI-II and compared to treatment costs per patient.
