Attitudes and practices toward anxiety among haemodialysis patients: a multicentre cross-sectional study in Qingdao, China
Published 2025-07-01“…For practices, attitude (β=0.281, p<0.001) and the same income category (β=1.512, p=0.011) were significant. Structural equation modelling identified anxiety’s direct effects on attitudes (β=0.218, p<0.001) and practices (β=−0.149, p<0.001), with attitudes positively affecting practices (β=0.380, p<0.001).Conclusions Patients undergoing haemodialysis exhibited high anxiety levels alongside proactive practices and negative attitudes. …”
