The Observational Evaluation of Subjective Well-Being in Patients with Rheumatoid Arthritis

An important aspect of general health is subjective well-being (SWB), which is defined as happiness and overall satisfaction with life. Herein we examined the reliability and validity of observation-based ratings of SWB in patients with rheumatoid arthritis (RA). Ten RA patients experiencing a disease flare (period of increased symptoms) completed two semi-structured interviews (baseline and 4 weeks later) that were digitally recorded. Twelve healthcare professionals watched the 20 brief videos in random order and scored them using the Well-Being Coding System (WBCS) for observer-reported SWB. Patient-reported SWB scores and scores from the Medical Outcomes Study: 36-Item Short Form Survey (SF-36) were compared to observer-reported scores for SWB. We found inter-rater reliability to be extremely high and a significant relationship between observer SWB composite scores and patient SWB composite scores. Observer SWB composite scores and other scores associated with SWB from the SF-36 were also related significantly. There was also some evidence supporting the ability of observers to detect change in SWB. Taken together, we found preliminary evidence suggesting that when using information gleaned from brief patient interviews clinicians can make reliable and valid evaluations of patients' SWB.
