Measuring compassion in end-of-life cancer patients: The Italian validation of the Sinclair Compassion Questionnaire (SCQit).

Objectives: Compassion is acknowledged as a key component of high-quality palliative care, producing positive outcomes for both patients and healthcare providers. The development of the Sinclair Compassion Questionnaire (SCQ) fulfilled the need for a valid and reliable tool to measure patients' experience of compassion. To validate the Italian version of the SCQ and to evaluate its psychometric properties in a sample of cancer patients with a life expectancy of less than 4 months.

Methods: Cronbach's alpha estimates were computed to evaluate the internal reliability. Exploratory Factor Analysis, Confirmatory Factor Analysis, and Item Response Theory analyses were performed to assess the validity of the construct. Divergent validity was assessed using the Functional Assessment of Chronic Illness Therapy-Treatment Satisfaction-Patient Satisfaction, the revised Edmonton Symptom Assessment Scale, and the Trust in Oncologist Scale-Short Form. Data were collected from 131 patients recruited in either a hospital or a hospice setting.

Results: The analyses confirmed the single factor structure of SCQit, with Confirmatory Factor Analysis factor loadings ranging between 0.81 and 0.92 and satisfactory internal reliability. Hospital setting and high diagnosis/prognosis awareness were associated with significantly lower SCQit scores, whereas practicing a religious faith was associated with greater experiences of compassion.

Significance of results: The Italian version of the SCQ (SCit) is a valid and reliable measure of patient-reported compassion. The SCQit can be used in clinical practice and research to measure the compassion experiences of terminally ill cancer patients and to evaluate the effectiveness of training to promote compassionate care in healthcare professionals.
