Hemodialysis and anxiety. Severe anxiety often accompanies patients who must undergo chronic hemodialysis. A study was undertaken to determine the effects of a set of progressive relaxation exercises on anxiety in hemodialysis patients. The treatment group consisted of 38 subjects who were shown a set of progressive relaxation videotapes. The control group was made up of 23 patients shown a set of neutral videotapes. A psychiatric questionnaire that measured anxiety revealed the posttest results reported in Table 12.14.
