Fatigue Impact Scale

The Fatigue Impact Scale (FIS) is a questionnaire used to assess how fatigue affects a person's daily life. It measures the physical, cognitive, and psychosocial effects of fatigue, such as tiredness, difficulty concentrating, and emotional challenges. Healthcare providers use it to understand how fatigue impacts someone's activities, relationships, and overall well-being, especially for individuals with conditions like multiple sclerosis or chronic illnesses. The goal is to identify specific areas of difficulty to tailor effective management strategies and improve quality of life.
