Chronic Pain Acceptance Questionnaire
Chronic Pain Acceptance Questionnaire (CPAQ) · Also known as: CPAQ, Acceptance and Commitment Therapy Pain Scale
The Chronic Pain Acceptance Questionnaire (CPAQ) is a 20-item self-report instrument developed by McCracken in 1998 to measure pain acceptance—the willingness to experience pain while continuing with valued life activities. Unlike pain management approaches focused on pain reduction, the CPAQ operationalizes acceptance-based treatment philosophy grounded in Acceptance and Commitment Therapy (ACT), measuring psychological flexibility in the context of chronic pain.

When to use it
The CPAQ is indicated for assessment of chronic pain patients (all diagnoses) to measure psychological flexibility and readiness for acceptance-based interventions. It is particularly useful for identifying patients stuck in pain-avoidance cycles (low CPAQ scores) who would benefit from Acceptance and Commitment Therapy or mindfulness-based pain management. The CPAQ is ideal for tracking progress in ACT-based pain rehabilitation programs and research investigating acceptance-based mechanisms of pain disability reduction. The CPAQ is less appropriate for acute pain or immediate postoperative pain where focus on pain reduction is primary.
Strengths & limitations
- Operationalizes pain acceptance as distinct psychological construct with strong theoretical grounding in ACT and psychological flexibility models
- Good psychometric properties: Cronbach's alpha ≥0.78-0.87 across subscales, test-retest reliability r ≥0.73-0.81, convergent validity with disability, depression, and functional outcomes
- Responsive to change: CPAQ improves with Acceptance and Commitment Therapy and mindfulness-based interventions; sensitive to acceptance-based treatment effects
- Predicts treatment outcomes and long-term disability independent of pain intensity; high CPAQ at baseline predicts better functional prognosis
- Brevity and availability; 8-item short form available for rapid screening; free and publicly available
- Measures willingness to experience pain but does not assess actual pain reduction; acceptance-based approach may not satisfy patients seeking pain elimination
- Activity Engagement subscale overlaps conceptually with self-efficacy; CPAQ and PSEQ measure related but distinct constructs
- Acceptance conceptualization may not align with all cultural frameworks; some populations emphasize pain elimination over psychological acceptance
- Low CPAQ may reflect realistic assessment of activity limitations rather than maladaptive avoidance; clinical judgment needed to distinguish functional limitation from psychological avoidance
Frequently asked
Does pain acceptance mean giving up on pain reduction?
No. Pain acceptance is not resignation but a change in relationship to pain. Accepting pain means acknowledging it exists while continuing with valued activities—not waiting for pain elimination to resume living. Many patients pursue both pain reduction (medication, physical therapy) and pain acceptance (mindfulness, valued-living) simultaneously. Acceptance removes the struggle against pain that paradoxically increases suffering.
If a patient has low CPAQ, do they need ACT?
Low CPAQ suggests pain-avoidance patterns and low willingness to engage despite pain. These patients often benefit from acceptance-based interventions like ACT, but not exclusively—cognitive-behavioral therapy addressing fear-avoidance and catastrophizing, activity pacing, and pain education also build acceptance. Start with lowest-barrier intervention; if avoidance persists, escalate to ACT.
Can acceptance increase pain intensity?
No. Paradoxically, acceptance typically decreases experienced pain intensity over time. When patients stop fighting pain and avoiding activities, pain becomes less central to their identity, and neuroplastic changes occur through graded activity. Initial pain during activity exposure may increase, but overall pain intensity and disability typically decrease with acceptance-based treatment.
How long does it take to increase CPAQ scores?
CPAQ changes develop gradually during acceptance-based treatment. Expect small increases (5-10 points) over 4-6 weeks of ACT; substantial improvements (20-30 points) typically appear at 8-12 weeks. Some gains occur rapidly (first 2-4 weeks) as cognitive shifts occur; others take longer as behavioral habits change. Assess CPAQ every 2-4 weeks to track progress.
