Patient education DVD effects on ESRD patients’
uncertainty
Table 3 shows significantly lower post-test uncertainty scores
for experimental group participants, as confirmed using an
independent-sample t-test and repeated measures ANOVA.
Averages for the differences between the four lots all reached
levels of significance, as checked using repeated measures
ANOVA and multiple comparison of scores using LSD.
Inspection of the variety of uncertainty scores of patients in
both groups at different time periods found significant
interaction (F = 58Æ07, p < 0Æ001; see Fig. 2). This indicated
significant improvement in uncertainty following the DVD
intervention.
