What is the Most Valid and Reliable Compassion Measure in Healthcare? An Updated Comprehensive and Critical Review.

Our previous review of compassion measures in healthcare between 1985 and 2016 concluded that no available measure assessed compassion in healthcare in a comprehensive or methodologically rigorous fashion. The present study provided a comparative review of the design and psychometric properties of recently updated or newly published compassion measures. The search strategy of our previous review was replicated. PubMed, MEDLINE, CINAHL, and PsycINFO databases and grey literature were searched to identify studies that reported information on instruments that measure compassion or compassionate care in clinicians, physicians, nurses, healthcare students, and patients. Textual qualitative descriptions of included studies were prepared. Instruments were evaluated using the Evaluating Measures of Patient-Reported Outcomes (EMPRO) tool. Measures that underwent additional testing since our last review included the Compassion Competence Scale (CCS), the Compassionate Care Assessment Tool (CCAT)©, and the Schwartz Center Compassionate Care Scale (SCCCS)™. New compassion measures included the Sussex-Oxford Compassion for Others Scale (SOCS-O), a self-report measure of compassion for others; the Bolton Compassion Strengths Indicators (BSCI), a self-report measure of the characteristics (strengths) associated with a compassionate nurse; a five-item Tool to Measure Patient Assessment of Clinician Compassion (TMPACC); and the Sinclair Compassion Questionnaire (SCQ). The SCQ was the only measure that adhered to measure development guidelines, established initial construct validity by first defining the concept of interest, and included the patient perspective across all stages of development. The SCQ had the highest EMPRO overall score at 58.1, almost 9 points higher than any other compassion measure, and achieved perfect EMPRO subscale scores for internal consistency, reliability, validity, and respondent burden, which were up to 43 points higher than any other compassion measure. These findings establish the SCQ as the 'gold standard' compassion measure, providing an empirical basis for evaluations of compassion in routine care.

Development and validation of a patient-reported measure of compassion in healthcare: the Sinclair Compassion Questionnaire (SCQ).

OBJECTIVES: Compassion is a key indicator of quality care that is reportedly eroding from patients' care experience. While the need to assess compassion is recognised, valid and reliable measures are lacking. This study developed and validated a clinically informed, psychometrically rigorous, patient-reported compassion measure. DESIGN: Data were collected from participants living with life-limiting illnesses over two study phases across four care settings (acute care, hospice, long term care (LTC) and homecare). In phase 1, data were analysed through exploratory factor analysis (EFA), with the final items analysed via confirmatory factor analysis (CFA) in phase 2. The Schwartz Center Compassionate Care Scale (SCCCS), the revised Edmonton Symptom Assessment Scale (ESAS-r) and Picker Patient Experience Questionnaire (PPEQ) were also administered in phase 2 to assess convergent and divergent validity. SETTING AND PARTICIPANTS: 633 participants were recruited over two study phases. In the EFA phase, a 54-item version of the measure was administered to 303 participants, with 330 participants being administered the final 15-item measure in the CFA phase. RESULTS: Both EFA and CFA confirmed compassion as a single factor construct with factor loadings for the 15-item measure ranging from 0.76 to 0.86, with excellent test-retest reliability (intraclass correlation coefficient range: 0.74-0.89) and excellent internal reliability (Cronbach's alpha of 0.96). The measure was positively correlated with the SCCCS (r=0.75, p<0.001) and PPEQ (r=0.60, p<0.001). Participants reporting higher experiences of compassion had significantly greater well-being and lower depression on the ESAS-r. Patients in acute care and hospice reported significantly greater experiences of compassion than LTC residents. CONCLUSIONS: There is strong initial psychometric evidence for the Sinclair Compassion Questionnaire (SCQ) as a valid and reliable patient-reported compassion measure. The SCQ provides healthcare providers, settings and administrators the means to routinely measure patients experiences of compassion, while providing researchers a robust measure to conduct high-quality research.
