Identifying cognitive-affective mechanisms underlying disability in episodic migraine: Using the fear avoidance model...

Area of Science:

• Neurology
• Psychology

Background:

• Migraine is a common neurological disorder causing significant daily life impairment.
• While biological and psychosocial factors are known contributors, a comprehensive model for migraine disability is lacking.

Purpose of the Study:

• To examine factors contributing to disability in episodic migraine using the fear-avoidance model (FAM).
• To test if pain catastrophizing, fear of attacks, and depressiveness mediate the relationship between pain experience and disability.

Main Methods:

• A cross-sectional online survey of episodic migraine patients was conducted.
• Confirmatory path analyses were performed using the Pain Disability Index and Migraine Disability Assessment questionnaire.
• Mediators included pain experience (frequency, intensity), pain catastrophizing, fear of attacks, and depressiveness.

Main Results:

• Both models showed good fit, explaining 28% of the variance in migraine-related disability.
• Attack frequency, pain intensity, fear of attacks, and depressiveness were independent predictors of disability.
• An indirect pathway from pain experience to disability via pain catastrophizing, fear of attacks, and depressiveness was confirmed.

Conclusions:

• The study supports the FAM, emphasizing the role of potentially modifiable cognitive pain processing.
• Identified predictors of disability include attack frequency, pain intensity, fear of attacks, and depressiveness.
• Pain catastrophizing is a key cognitive-affective factor mediating the link between pain experience and disability.
