In the world of psychology research, making accurate and valid comparisons between different assessment tools is vital. Enter the PHQ-9 vs SCAN debate. The PHQ-9, or Patient Health Questionnaire, is a popular, self-assessed tool often used to diagnose common mental disorders. On the other hand, the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) consists of over 1800 possible items, providing a more comprehensive, though perhaps wider, scope. While both have their merits, comparing their effectiveness and appropriateness in various scenarios can be challenging and time-consuming. This is where Harmony steps in.
