Functional Impairment
Functional impairment is the degree to which mental health symptoms interfere with everyday roles — work, home, relationships, and leisure.
Definition
Clinicians care not only about symptom counts but about how much life is disrupted. Functional impairment covers difficulties working or studying, managing home tasks, maintaining close relationships, and enjoying social or private leisure. The Work and Social Adjustment Scale (WSAS) briefly rates these domains. High impairment alongside mood or anxiety symptoms is a reason to seek professional support.
What it can feel like
- Missing work or underperforming because of anxiety or low mood.
- Letting housework or self-care slip for weeks.
- Withdrawing from friends or family.
- Dropping hobbies you used to manage.

The WSAS rates impairment in work, home management, social leisure, private leisure, and close relationships.
Is functional impairment a diagnosis?
No. It is a dimensional description of impact. Diagnoses are separate clinical judgments.
