Association Between Antidepressant Adherence And Major Depressive Disorder Complications, Philip Lisinge Jan 2023

Association Between Antidepressant Adherence And Major Depressive Disorder Complications, Philip Lisinge

Walden Dissertations and Doctoral Studies

Despite evidence that antidepressants are more effective at treating major depressive disorder (MDD) symptoms, there is growing evidence that MDD management is still hampered by nonadherence to antidepressant treatment regimens. Researchers have suggested that MDD, if untreated, might lead to MDD-related complications, but other researchers have argued that adherence to antidepressants can lead to these same MDD-related complications. This quantitative cross-sectional study used primary data collected from 298 volunteers to examine the association between MDD-related complications and antidepressant adherence to clarify these diverging opinions. The study’s objective was to provide evidence to accept or reject the premise that antidepressant adherence …
