Relation between catastrophizing and depression in chronic pain patients

Area of Science:

• Psychology
• Pain Medicine
• Clinical Psychology

Background:

• Chronic pain is often associated with psychological distress, including depression.
• Catastrophizing, a negative cognitive response to pain, is frequently studied in relation to pain and mood.
• The conceptual and operational overlap between catastrophizing and depression requires careful examination.

Purpose of the Study:

• To examine the relationship between catastrophizing, depression, and coping strategies in chronic pain patients.
• To investigate potential measurement redundancy between catastrophizing and depressive symptomatology.
• To clarify the distinct contributions of catastrophizing to depression in the context of chronic pain.

Main Methods:

• 125 chronic pain patients completed the Coping Strategies Questionnaire (CSQ).
• A subscale assessing catastrophizing was evaluated for overlap with depressive symptoms by 6 clinical psychologists.
• The catastrophizing subscale was removed from the CSQ, and remaining subscales were re-analyzed for their relationship with depression.

Main Results:

• A significant association was found between catastrophizing and depression.
• Clinical psychologists rated all items in the catastrophizing subscale as reflective of depressive symptoms.
• After removing the catastrophizing subscale, no significant relationship remained between the CSQ and depression.

Conclusions:

• The findings suggest that the catastrophizing construct, as measured by the CSQ, is operationally confounded with depression.
• The relationship between chronic pain, catastrophizing, and depression may be largely attributable to shared depressive symptomatology.
• Future research should carefully consider the conceptual and measurement overlap when examining these variables.
