Paired t-test and Wilcoxon’s test showed significant
changes between pre- and postintervention scores in state/
trait anxiety and perceived stress in the experimental group
(P .001). There were no significant changes between preand
posttest scores in state/trait anxiety for the control
group (P .10 and .972, respectively). There was a
significant increase between pre- and posttest scores in
perceived stress for the control group (P .001).
