The presence of a significant impairment in social and occupational functioning is a criterion for which diagnosis?

In the context of Major Depressive Disorder (MDD), a significant impairment in social and occupational functioning is indeed a key diagnostic criterion. This condition involves persistent feelings of sadness or a lack of interest in previously enjoyed activities, leading to disruptions in daily life. The DSM-5 specifies that for a diagnosis of MDD, the symptoms must cause clinically significant distress or impairment in social, occupational, or other important areas of functioning. This impairment can manifest as difficulties in maintaining relationships, performing at work, or engaging in everyday activities, highlighting the profound impact of the disorder on an individual's quality of life.

In contrast, while other disorders like Generalized Anxiety Disorder, Bipolar Disorder, and Obsessive-Compulsive Disorder can also lead to impairment in functioning, their primary diagnostic criteria focus on the specific symptoms and patterns unique to those disorders rather than explicitly including the requirement of significant impairment as a standalone criterion. Therefore, the focus on functional impairment as a hallmark characteristic aligns specifically with Major Depressive Disorder, reinforcing its importance in clinical diagnosis and treatment planning.
