Patient empowerment and self‐management behaviour of chronic disease patients: A moderated mediation model of self‐efficacy and health locus of control

To explore the role of self-efficacy (SE) in the effect of patient empowerment on self-management behaviours among patients with chronic illness and to investigate the moderating effect of three types of health locus of control (HLC) in this moderated mediation model.Cross-sectional design.Data were collected in a general tertiary hospital, and a sample of 254 patients was recruited between August and October 2020. The effect of moderation and mediation was tested by the PROCESS macro (Model 4 and Model 8) for SPSS 25.0 by Hayes using 5000 bootstrap samples.Self-efficacy significantly mediated the relationship between patient empowerment and self-management behaviour with a 95% confidence interval excluding zero. The chance HLC demonstrated a moderating effect, and the interaction effect on SE and self-management behaviour was significant.Patient empowerment may improve confidence and adherence to self-management among people with chronic illness, and such benefits were conditional on the HLC of patients.This study addresses the relationship between patient empowerment and self-management behaviour in patients with different personality characteristics. This result indicated that classifying the type of HLC may enable the identification of subgroups of patients who may subsequently benefit from patient empowerment. In a patient-centred programme, nurses and other healthcare professionals correctly identifying patients' HLC type and understanding the implications and then providing appropriate health care plans for patients with different health beliefs may be useful to tailor the decision-making process.
