The Renal Treatment Satisfaction Questionnaire (RTSQ): A measure of satisfaction with treatment for chronic kidney failure

Background: Quality and effectiveness of care can be enhanced through the use of condition-specific measures of satisfaction with treatment. The aim of the present study was to design and develop a measure of satisfaction with treatment for patients with chronic kidney failure (CKF) for use in routine clinical care and clinical trials. The Renal Treatment Satisfaction Questionnaire (RTSQ) was designed to be suitable for people using any of the various treatment modalities for CKF. Items measure satisfaction with aspects of treatment, including convenience, flexibility, freedom, and satisfaction to continue with present form of treatment. Methods: A 12-item RTSQ was investigated at a UK hospital-based renal unit, using data from 140 outpatients undergoing renal replacement therapy (hemodialysis, n = 35; continuous ambulatory peritoneal dialysis, n = 57; transplantation, n = 46). Results: An 11-item scale was developed from the original 12-item version, with a single factor accounting for 59% of the variance and item loadings greater than 0.58. Scale reliability was excellent (α = 0.93) in the full sample and proved robust to analysis in separate treatment subgroups. As expected, RTSQ scores differed significantly (P < 0.0001) between the transplantation and other treatment groups. Those who had received a transplant expressed greater overall satisfaction, with specific advantages of transplantation shown by all individual items, including convenience, time, lifestyle, freedom, and satisfaction to continue current treatment. Conclusion: The RTSQ provides a brief reliable measure of satisfaction with treatment for patients with CKF that is suitable for use in routine clinical care and clinical trials.
