Comparison of mean state anxiety before and after intervention in study groups.

| Combined aromatherapy and music therapy | 45.7 ± 3.1 | 44.8, 46.7 | 47.9 ± 2.3 | 47.1, 48.6 | |||
| Control | 46.5 ± 3.8 | 45.6, 47.5 | 45.9 ± 3.5 | 45.1, 46.7 | |||
| Test result | F = 0.577, P=0.631 | F = 6.765, P < 0.001§ | |||||
Note. The results of ANOVA test showed no statistically significant difference between the study groups in terms of mean anxiety before the intervention, but this difference was statistically significant after the intervention. The results of paired t-test showed a statistically significant difference between the mean anxiety scores before and after the intervention in the music therapy, aromatherapy, and combined aromatherapy and music therapy groups, but this difference was not significant in the control group. §The difference is significant at P < 0.05.
