Experimental group scores through the three posttests
showed an initial rise followed by the maintenance of
higher score levels. This demonstrates the greater effectiveness
of the patient education DVD intervention over traditional
patient education methods. The findings of this study
were similar to those of Klang et al. (1998, 1999), which
indicated that patient education prior to dialysis enhances
patients’ knowledge and dialysis decision-making. Findings
also coincided with those of Ruthman and Ferrans (2004)
who explored the effects of using an interactive multimedia
DVD in prostate cancer patient education to enhance
treatment cognition.
