Tukey HSD was used. According to the post hoc test, the posttest depression domain score of the control group significantly differed with that of the text messaging (P = 0.019) and DVD (P < 0.001) groups. Such significant posttest differences between the control group and the text messaging and DVD intervention groups were also seen in the anxiety (P = 0.071 and P = 0.006, respectively) and stress (P < 0.001 and P < 0.001, respectively) domains
