Introduction: Fibromyalgia syndrome (FMS) is a common pain syndrome associated with fatigue and anxiety. The aim of this survey was to determine the impact of fatigue on the quality of life (QoL) of people with FMS and to explore the relationships between fatigue, pain, and anxiety.
Methods: A postal survey was conducted among support groups. Demographic data were collected and participants were asked to complete the Multi-dimensional Assessment of Fatigue Scale (MAF) and two visual analog scales (VAS) measuring pain and anxiety. Data were analysed using descriptive statistics, and relationships between variables were explored using Pearson's correlation coefficient and Fisher's Exact Probability Test. Ethical approval was granted from Ulster University's research ethics committee.
Results: A response rate of 52.5% was achieved (105/200). Fatigue was found to severely impact the QoL of those with FMS. From the MAF, a mean Global Fatigue Index score of 40.7 (range 1 = no fatigue-50 = severe fatigue) was calculated. Fatigue was significantly associated with both pain (r = 0.674) and anxiety (r = 0.546) (both p values < 0.0001), and no significant relationship was found between the duration of FMS and fatigue (r = 0.106; p = 0.320).
Conclusion: Fatigue has a major impact on the QoL of patients with FMS. There is a strong relationship between fatigue and other variables such as pain and anxiety. However, there is no relationship between the time since diagnosis and fatigue experienced. Fatigue management should feature highly in any treatment programme for those with FMS.
