A quasi‑experimental designwas used in which a target sample of 30 hemodialysis patients, who received treatment at DolatabadHemodialysis Center, Isfahan, Iran, volunteered to participate in this study. They were then randomlydivided into two groups (i.e., control and experimental groups), 15 each.
