Patient Dignity Inventory
Patient Dignity Inventory (PDI) · Also known as: PDI, Dignity Inventory
The Patient Dignity Inventory (PDI) is a 25-item self-report measure assessing dignity-related distress in patients with advanced cancer and life-limiting illness. Developed by Chochinov and colleagues at the University of Manitoba in 2008, the PDI operationalizes 'dignity' as a multidimensional construct encompassing illness-related functional decline, psychosocial concerns (fear, hopelessness, suicidality), body image distress, existential meaning, and social connection—dimensions often overlooked by symptom-focused assessment. The PDI enables clinicians to identify and address dignity threats systematically, preventing the existential despair that can accompany terminal illness even when physical symptoms are well-controlled.

When to use it
The PDI should be administered at initial palliative care consultation to establish baseline dignity concerns and guide comprehensive care planning. Re-administer weekly during inpatient stays or monthly in outpatient/hospice settings to monitor whether interventions are addressing dignity threats. Administer immediately after acute events (functional decline, appearance change, family conflict, existential crisis) to assess dignity impact and guide response. Use before and after dignity-focused interventions (dignity therapy, meaning-centered psychotherapy, legacy work) to measure effectiveness. Especially valuable in research on palliative care quality-of-life outcomes, effectiveness of psychosocial/existential interventions, and relationships between dignity and depression/suicidality. Less useful for patients with advanced dementia, severe delirium, or non-communicative status, though observational dignity assessment can supplement.
Strengths & limitations
- Explicitly measures dignity—an often-overlooked dimension: Unlike pain or symptom scales, the PDI directly addresses existential and psychosocial dignity threats (loss of control, burden, loss of meaning, altered identity).
- Multidimensional and psychologically grounded: Based on Chochinov's empirical dignity model; distinguishes between illness-related concerns (physical/functional), dignity-conserving coping (meaning, hope, purpose), and social dignity (burden, family impact).
- Comprehensive without excessive burden: 25 items cover three major domains in 10–15 minutes; feasible for fatigued, seriously ill patients.
- Strong psychometric properties: Cronbach's α = 0.87–0.92 (total), 0.81–0.88 (subscales); test–retest reliability r = 0.80–0.88; responsive to change in dignity-focused interventions.
- Extensive validation across diverse populations: Cancer (lung, breast, prostate, GI), organ failure (renal, cardiac), neurological disease, HIV/AIDS; validated in multiple languages (English, French, Spanish, German, Chinese, Japanese).
- Self-report vulnerable to social desirability: Patients may minimize dignity concerns to avoid burdening clinicians or to seem 'coping well'; clinical observation and direct conversation supplement scores.
- Conceptual overlap with depression and anxiety: Some PDI items are similar to depression/anxiety scales (hopelessness, loss of control, fear); low PDI partially reflects depressive symptoms rather than pure 'dignity' construct.
- Not a diagnostic tool: High PDI indicates dignity distress warranting support, but does not diagnose depression, suicidality, or existential despair; always conduct separate mood and suicide risk assessment.
- Dependent on cognitive capacity and language: Requires intact abstraction and reflection; items use complex language (e.g., 'autonomy,' 'existential meaning'); not valid for patients with dementia, aphasia, or low health literacy without adaptation.
- Limited evidence for intervention specificity: Identifying high dignity distress is useful, but PDI does not prescribe which type of intervention (dignity therapy vs. counseling vs. family work) is optimal; clinical judgment required.
Frequently asked
If a patient has high dignity distress but denies depression, what does that mean?
Dignity distress and depression are related but distinct. A patient may have profound dignity concerns (feels burdensome, loss of control, altered identity) without clinical depression (sadness, anhedonia, guilt). However, prolonged dignity distress can lead to depression if unaddressed. Treat the dignity concerns directly through dignity therapy, meaning-centered work, and family communication. Monitor for emergent depression with PHQ-9 or similar.
What is 'Dignity Therapy,' and how does it differ from regular counseling?
Dignity Therapy is a specific brief psychotherapeutic intervention developed by Chochinov for advanced cancer patients targeting PDI-identified dignity concerns. Sessions (typically 1–3) focus on life narrative, legacy, and meaning—clinician helps patient articulate what matters most, create a document or recording for family, and reconnect with a sense of purpose. Regular counseling addresses emotional distress and coping broadly; Dignity Therapy is existentially and narratively focused. Both are valuable; Dignity Therapy is specifically designed for dignity-related distress identified by the PDI.
How do I interpret low Dignity-Conserving Repertoire (patient has lost hope and sense of purpose)?
Low Dignity-Conserving Repertoire (subscale <18) indicates the patient has lost sense of control, purpose, hope, and meaning—serious existential distress. This is high priority for intervention: Meaning-centered psychotherapy, chaplaincy, legacy work, or Dignity Therapy. In severe cases, existential despair can lead to suicidality or hastened death wishes; screen for suicide risk and psychiatric support. This subscale is a sign that the patient needs more than symptom management—they need existential and spiritual support.
Can I use PDI with families to measure their dignity distress?
The PDI was designed for patients, not families. However, families have parallel dignity concerns (watching loved one decline, feelings of helplessness, moral distress). Use the PDI to identify patient concerns, then assess family perspectives separately through conversation ('How are you coping with seeing your mother like this?') and offer family counseling, support groups, or social work to address family dignity/burden concerns. Caregiver Quality of Life Index–Cancer or similar tools can measure family distress.
