Mechanisms and Effects of Health Coaching in Patients With Early‐Stage Chronic Kidney Disease: A Randomized Controlled Trial

Abstract Purpose To examine the effects of health coaching on self‐management and quality of life (QOL) in patients with chronic kidney disease (CKD) and to evaluate whether self‐efficacy and patient activation mediate the effect of health coaching on self‐management and QOL. Design and Methods A single‐center, parallel‐group, randomized controlled trial. A total of 108 patients with stages 1 to 3a CKD participated in the study. Participants were randomly assigned to a health‐coaching intervention group or a usual care control group. Participants’ QOL (World Health Organization Quality of Life Scale), self‐management (CKD Self‐Management instrument), patient activation (Patient Activation Measure), and self‐efficacy (CKD Self‐Efficacy instrument) were measured at baseline, immediately after, and 6 weeks after the intervention. Findings Health coaching improved QOL, self‐management, patient activation, and self‐efficacy at postintervention and at 12 weeks’ follow‐up. Health coaching had a significant indirect effect on QOL through improvements in patient activation. Health coaching exerted a significant indirect effect on self‐management through improvements in self‐efficacy and patient activation. Conclusions The findings demonstrated that health coaching can effectively improve QOL and self‐management. A health‐coaching intervention can raise self‐efficacy and activation levels through which self‐management and QOL further improve. Clinical Relevance Health‐coaching strategies can be used to assist patients with early‐stage CKD in reaching their health goals and becoming activated in self‐management of their diseases.
