Composite, fully anonymized vignette. Initials and details are illustrative.

Presenting concern

Referred by pain medicine. PHQ-9: 17. Withdrawn from former hobbies (cycling, woodworking), gained 30 lbs, marital strain. Off opioids 6 months, now on duloxetine. Pain still present but more manageable.

History

Workplace back injury 4 years ago. Cascade: surgery → opioid dependence → taper → depression. Previously highly active. No prior psychiatric history.

Risk factors
  • Identity loss around physical capability
  • Deconditioning compounding pain
  • Marital strain
  • Pain-related fear avoidance
Strengths
  • Off opioids
  • Engaged with pain medicine team
  • Wife still supportive
  • Has prior identity to draw on

Conceptualization across modalities

ACT for chronic pain

Pain catastrophizing + fear-avoidance + life narrowing = chronic pain depression. Treatment is not to eliminate pain but to expand life despite it. Values clarification + willingness + committed action.

Treatment targets
  • Defusion from 'I can't until pain is gone' thinking
  • Values clarification
  • Graded behavioral activation in values direction
  • Willingness to feel pain in service of meaningful action
CBT for chronic pain (BA + cognitive)

Behavioral withdrawal from valued activity drives depression independent of pain. Cognitive distortions ('I'm broken,' 'I'll never get my life back') maintain hopelessness. Graded activation + cognitive work targets both.

Treatment targets
  • Graded activity scheduling (paced, not pain-contingent)
  • Thought records on pain-related cognitions
  • Sleep hygiene
  • Address fear-avoidance behaviors

Treatment plan

1

Engage (1–4)

Formulation, values clarification, pacing introduction.

2

Activate (5–14)

Graded activity, willingness work, marital re-engagement.

3

Identity (15–20)

Reconstruct identity beyond 'former athlete / disabled.'

Outcome note

PHQ-9 to 8 by session 16. Returned to modified cycling. Identity shift in progress, ongoing.
