Tool Description:

The UW-SES-6 is a short-form scale that measures the ability of patients with chronic conditions to deal with challenges related to those chronic conditions.
Questions on the short form scale ask patients with chronic conditions about how their conditions affect their social life, physical health, mental health, as well as other factors.
