Caregiver Quality of Life Index–Cancer

Not necessarily—low CQOLC indicates poor quality of life and high burden, but it is not equivalent to depression. However, depression and poor QoL are correlated; caregivers with CQOLC <90 should be screened for depression with a validated tool (PHQ-9: score ≥10 suggests depressive disorder). Even without depression, low CQOLC warrants urgent support: identify the specific low subscale (Burden? Financial Concerns?) and tailor interventions (respite, financial counseling, support groups).

CQOLC is validated specifically in cancer caregiving; while many items generalize, using it in non-cancer populations introduces measurement uncertainty. For non-cancer, consider general caregiver burden scales (Zarit Burden Interview, Caregiver Strain Index) or disease-specific measures (dementia caregiver burden, heart failure caregiver strain). That said, some palliative care researchers do use CQOLC across conditions; acknowledge the validity limitations if doing so.

Positive Adaptation (8 items) captures the caregiver's sense of meaning, relationship strengthening, and personal growth through caregiving—e.g., 'Caregiving has given me a sense of purpose.' A high subscale score (>3.5) is protective against depression and burnout. A low score (<2.5) does NOT mean the caregiver is failing; it means they are not experiencing meaning-making, which is a risk factor. Offer support groups, spiritual or existential counseling, or legacy work to help the caregiver find meaning. Do not expect all caregivers to find meaning—respect their authentic experience.

Yes, but with sensitivity. Frame it as a tool to identify support needs, not a judgment. Example: 'This score tells us you're managing a lot. Here are three forms of support that can help: [respite care, counseling, support group]. Which would be most helpful for you?' Avoid pathologizing language; instead, normalize caregiver distress and emphasize that support improves outcomes for both caregiver and patient.
