Pain Management and Chronic Pain

Pain is a multidimensional experience with sensory, emotional, and cognitive components, and chronic pain — pain that persists beyond normal healing — is shaped by psychological and social factors as well as biological ones. Clinical health psychology contributes to understanding and managing pain through biopsychosocial assessment and psychological interventions that address the thoughts, emotions, and behaviors surrounding pain.

Definition

Pain management and chronic pain, as a topic in clinical health psychology, concerns the psychological understanding, assessment, and treatment of pain — particularly persistent pain — within a biopsychosocial framework that integrates biological nociception with cognitive, emotional, and social influences.

Scope

This entry covers the psychology of pain, the biopsychosocial model of chronic pain, the assessment of pain as a subjective experience, and the evidence for psychological therapies in chronic-pain management. It is a reference overview and does not provide treatment regimens, medication guidance, or individualized pain-management plans.

Core questions

• How do psychological and social factors influence the experience and persistence of pain?
• How is a subjective experience such as pain assessed and measured?
• What is the evidence for psychological therapies in chronic pain?
• How does the biopsychosocial model differ from a purely biomedical view of pain?

Key concepts

• Chronic versus acute pain
• Biopsychosocial model of pain
• Pain catastrophizing and fear-avoidance
• Self-report pain assessment
• Cognitive behavioral therapy for pain
• Pain communication

Key theories

Biopsychosocial model of chronic pain

Gatchel and colleagues' integrative framework in which chronic pain emerges from the interplay of biological, psychological, and social factors, providing the dominant model for pain research and assessment.

Gate control theory of pain

Melzack and Wall's proposal that spinal 'gating' mechanisms modulate pain signals and can be influenced by cognitive and emotional factors, establishing a basis for psychological contributions to pain.

Mechanisms

In the biopsychosocial account, nociceptive signaling interacts with cognitive appraisal (such as catastrophizing and beliefs about pain), emotional states (such as fear and low mood), and behavioral responses (such as avoidance and disability), as well as with the social environment, to shape the experience and persistence of pain. Gatchel and colleagues synthesize the scientific advances supporting this view, and Hadjistavropoulos and colleagues describe how pain is communicated and interpreted between people. Because pain is subjective, assessment relies on self-report instruments such as the McGill Pain Questionnaire developed by Melzack.

Clinical relevance

Psychological models and assessment of pain inform multidisciplinary pain care and the rationale for psychological therapies alongside medical management. This entry summarizes concepts and evidence as reference material and does not recommend specific analgesic, procedural, or psychological treatments for any individual.

Evidence & guidelines

A Cochrane systematic review by Williams and colleagues evaluates psychological therapies, including cognitive behavioral therapy, for chronic pain in adults, finding effects on pain, disability, and distress that inform their role within multidisciplinary care. The biopsychosocial syntheses by Gatchel and colleagues and Hadjistavropoulos and colleagues provide the conceptual evidence base.

History

The modern psychology of pain was reshaped by Melzack and Wall's 1965 gate control theory, which made room for cognitive and emotional modulation of pain. This was followed by the development of self-report measures such as the McGill Pain Questionnaire and by the consolidation of the biopsychosocial model of chronic pain, synthesized by Gatchel and colleagues in 2007, which became the dominant framework for research and assessment.

Debates

How large and durable are the effects of psychological therapies for chronic pain?

Systematic reviews find that psychological therapies such as cognitive behavioral therapy produce real but generally modest improvements in pain, disability, and distress, prompting ongoing discussion about optimizing and tailoring these treatments.

Frequently asked questions

What does the biopsychosocial model of chronic pain mean?

It is the view that chronic pain results from the interaction of biological processes, psychological factors such as beliefs and emotions, and social context, rather than from tissue damage alone.

Can psychological therapy help with chronic pain?

Systematic reviews indicate that psychological therapies such as cognitive behavioral therapy can produce modest improvements in pain, disability, and distress for chronic pain; this is a general research finding and not advice for any individual.
