Personality as a Predictor of Disability in Multiple Sclerosis

Area of Science:

• Neurology
• Psychology

Background:

• Personality changes and disorders are common in multiple sclerosis (MS).
• Personality may serve as a prognostic factor in MS.
• Understanding personality's role can improve patient care.

Purpose of the Study:

• To investigate the influence of personality on disability, progression, and treatment adherence in MS patients.
• To explore personality as a potential prognostic factor for MS outcomes.

Main Methods:

• Assessed personality using the NEO Personality Inventory-3rd edition in 41 Relapsing-Remitting MS patients.
• Measured disability with the Expanded Disability Status Scale.
• Collected treatment adherence data and performed correlational and regression analyses.

Main Results:

• Neuroticism and its Vulnerability facet predicted greater MS disability.
• Extraversion and its Activity facet predicted milder MS disability.
• Extraversion and Openness (Feelings facet) were negatively correlated with disability progression, though not significant in regression models. No significant impact on treatment adherence was found.

Conclusions:

• Specific personality traits, particularly Neuroticism and Extraversion, significantly impact disability in MS.
• These personality factors should be considered in clinical practice for MS patients.
• Tailoring clinical support based on personality traits may enhance patient outcomes.
