Effects of DVD intervention on ESRD patient uncertainty
This study found significant differences (p < 0Æ05, Table 3)
between average experimental group patient pretest scores
and four-week and eight-week follow-up post-test scores.
This study used a researcher-developed interactive multimedia
patient education DVD to explore the effects of
reducing predialysis uncertainty in patients with ESRD and
found a significantly positive effect owing to the generally
insufficient predialysis knowledge delivered to patients by
traditional means. This study achieved results similar to those
of Murray et al. (2001), who used an interactive multimedia
DVD intervention to lower uncertainty in climacteric women
accepting hormone remedies.
Effects of DVD intervention on ESRD patient decisionmaking
regret
Twenty-three experimental group (HD: 17 persons, PD: six
persons) and seventeen control group (HD: 13 persons, PD:
four persons) subjects chose dialysis as their treatment
option. Average decision regret was 17Æ83 (SD 13Æ32) for
the experimental and 47Æ35 (SD 20Æ09) for the control group.
Independent-sample t-test confirmed significantly less
(p < 0Æ000) decision regret amongst experimental group
subjects. The average 17Æ83 (SD 12Æ32) value for decision
regret in the experimental group coincides with the findings
of Davision and Goldenberg (2003) and Potosky et al.
(2000). The former explored decision regret amongst patients
with prostate cancer following a patient education interactive
multimedia DVD intervention and earned an average decision
regret value of 15Æ6 (SD 16). The latter provided patients
health education prior to treatment and found that 92% of
subjects receiving an operation or irradiation therapy did not
regret their treatment decision two years afterwards. Results
of this and numerous other studies show that enhanced
patient education using an interactive multimedia DVD–
based intervention helps patients make significantly more
satisfactory treatment decisions compared with traditional
