The FSS is a nine-item instrument designed to assess fatigue as a symptom of a variety of different chronic conditions and disorders. The scale addresses fatigue’s effects on daily functioning, querying its relationship to motivation, physical activity, work, family, and social life, and asking respondents to rate the ease with which they are fatigued and the degree to which the symptom poses a problem for them.
