Personality traits in multiple sclerosis (MS) patients with and without fatigue experience

Area of Science:

• Psychology
• Neurology
• Medical Research

Background:

• Fatigue is a common and debilitating symptom in multiple sclerosis (MS).
• Understanding the factors contributing to MS fatigue is crucial for effective management.
• The role of psychological factors, particularly personality, in MS fatigue requires further investigation.

Purpose of the Study:

• To investigate the influence of specific personality characteristics on the experience of fatigue in patients with multiple sclerosis.
• To compare the impact of personality traits on MS fatigue with the impact of physical disability.

Main Methods:

• Eighty patients diagnosed with definite multiple sclerosis (MS) participated in the study.
• Participants completed questionnaires assessing fatigue and personality traits (Freiburg Personality Inventory-Revised; FPI-R).
• Clinical assessment of physical impairment was conducted using the Expanded Disability Status Scale (EDSS).

Main Results:

• Increased neuroticism and excitability, along with decreased extraversion, were independently associated with higher fatigue levels in MS patients.
• Personality traits explained a significant portion of the variance in fatigue (partial R2 up to 0.32), substantially more than physical impairment (partial R2 up to 0.04).

Conclusions:

• The findings support a psychological model for understanding fatigue in multiple sclerosis.
• Personality assessment tools like the FPI-R may help identify individuals with MS at higher risk for fatigue.
• These results highlight the importance of considering psychological factors in the management of chronic fatigue in MS.
