Assessing Patient-Centred Care for Chronic Pain: Validation of a New Research Paradigm

Abstract

BACKGROUND: Chronic pain is a complex phenomenon resulting from biological, psychological and social factors, and the use of patient-centred care (PCC) appears to be a promising avenue for its treatment. Various methods have been used for measuring PCC in nurses and physicians (caregivers); however, methodological problems have been raised following the observation of real clinical encounters or standardized patient simulations. The development of new strategies is required.OBJECTIVE: To develop and validate an observation scale for the assessment of PCC in caregivers, using standardized videos of real patients with chronic pain.METHODS: An expert panel developed five videos and the Sherbrooke Observation Scale of Patient-Centered Care (SOS-PCC), which were tested in a sample of 21 nurses and 21 physicians working with chronic pain patients. The content validity, internal consistency and inter-rater reliability of the SOS-PCC were assessed.RESULTS: The expert panel was satisfied with the content validity of the SOS-PCC. Results revealed good internal consistency (Cronbach’s alpha = 0.88) and inter-rater reliability (intraclass coefficient = 0.93) for this scale.CONCLUSIONS: To the authors’ knowledge, the SOS-PCC is the first instrument available in French to assess PCC behaviour of caregivers using videos of real patients with chronic pain. The psychometric qualities of these instruments are good. Future studies will need to assess this instrument with other populations of caregivers.
