Pain-Related Coping Behavior in ALS: The Interplay between Maladaptive Coping, the Patient's Affective State and Pain

Area of Science:

• Neurology
• Pain Management
• Psychology

Background:

• Pain is a frequent and significant symptom for individuals diagnosed with amyotrophic lateral sclerosis (ALS).
• Effective coping mechanisms are crucial for patients to adjust to and manage their pain experience.

Purpose of the Study:

• To evaluate the utilization of various pain coping strategies among ALS patients.
• To investigate the relationship between maladaptive coping, affective state, and pain severity in ALS.

Main Methods:

• 150 ALS patients from German clinics completed validated questionnaires assessing pain (Brief Pain Inventory), function (ALS-Functional Rating Scale-Extension), depression (ALS Depression Inventory), emotional functioning (ALS Assessment Questionnaire), and coping strategies (Coping Strategies Questionnaire).
• Correlational and multiple regression analyses were employed to identify predictors of pain and factors contributing to maladaptive coping.

Main Results:

• Pain affected 56% of the ALS patients studied.
• The maladaptive coping strategy of "catastrophizing" significantly predicted higher pain intensity, accounting for 34% of the variance.
• Catastrophizing was linked to greater functional impairments and poorer emotional well-being. Depressive symptoms (ALS Depression Inventory) significantly predicted catastrophizing, explaining 40.8% of its variance.

Conclusions:

• ALS patients utilize diverse pain coping strategies, with "catastrophizing" being a key factor in increased pain intensity and interference.
• Pain-related catastrophizing is exacerbated by depressive symptoms, negatively impacting emotional well-being.
• Addressing catastrophizing and depressive symptoms is vital for developing individualized pain management interventions in ALS care.
