Specific Aim #3: Demonstrate that Fatigue: Take Control results in changes in medication utilization, exercise participation, sleep and health-related quality of life in people with MS who are ambulatory and not depressed. Fatigue affects body functions/structure, activity and participation in all aspects of daily life. Fatigue: Take Control was created with the expectation that fatigue can be reduced by guiding individuals to make the environmental, behavioral and lifestyle changes necessary to manage MS fatigue. This objective will explore important secondary causes of fatigue that impact health-related quality of life by identifying participant changes in: timed walk using the time to walk 25 feet (T25-FW), medication utilization using a self-report medication diary, exercise participation using the self-report Rapid Assessment of Physical Activity (RAPA), sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and changes in overall health-related quality of life using the SF-36.
