This course provides an in-depth introduction to the Symptoms of Depression Questionnaire (SDQ), a self-rating scale for tracking a wide range of depression symptoms over time. Through three video lessons, Dr. Maurizio Fava explains the development and clinical benefits of the SDQ, offers practical tips for encouraging patient engagement, and emphasizes the importance of focusing treatments on the most troubling symptoms. A demonstration of the SDQ workflow and guidance on interpreting score ranges are included. The course concludes with a short feedback survey to gather participant insights.
