The control group received no intervention. Amsterdam questionnaire was used to assess preoperative anxiety. Data was analyzed by SPSS software (version 19) and t-test and ANOVA. P<0.05 was considered significant. Results: The mean score of total anxiety in the control group was 21.92±4.99 and in the experimental group was 17.44±5.88, and the difference was statistically significant (p<0.05). No significant relationship was observed between anxiety score in both groups and demographic factors of the samples.
