Multiple Sclerosis Fatigue Self-Management: Strategies and Influencing Factors 5 Years After a Multimodal Intervention.

BACKGROUND

Fatigue: Take Control (FTC) is a multimodal self-management program. Results of a previous clinical trial showed its effectiveness at improving fatigue related to multiple sclerosis (MS). The objectives of this study were to use the very long-term data from the FTC study to understand fatigue management strategies used 5 years after enrollment, identify facilitators and barriers to utilizing strategies, and explore the potential relationships between the strategy used and fatigue outcomes.

METHODS

This study adopted a cross-sectional survey design. A subset of the original FTC clinical trial participants was invited to complete the Modified Fatigue Impact Scale for fatigue severity measurement and a 17-item questionnaire about their fatigue management strategies 5 years after enrollment. Descriptive statistics and content analysis were used to analyze quantitative and qualitative data using the COM-B (capability, opportunity, motivation-behavior) model for behavior change as a framework.

RESULTS

Planning daily activities and prioritizing tasks were the fatigue management strategies most often reported. Facilitators to utilizing management strategies included access to enabling devices, paid professional help, companions, and maintaining a positive attitude. Barriers to implementing strategies included high cost, the presence of other health problems, and temperature sensitivity. Internal focused strategies showed a trend toward reducing fatigue impact when controlled for typology group assignment.

CONCLUSIONS

Future work may focus on promoting low-cost strategies to help people with MS manage fatigue. Internal factors (eg, motivation) play an important role in influencing the application of MS fatigue self-management strategies. Future clinical trials with larger sample sizes that assess the applicability of the COM-B model are warranted.
