Background: Test anxiety is a common problem among Iranian students. In this study, we
aimed to evaluate the effect of aromatherapy with lavender on test anxiety.
Materials and Methods: This randomized clinical trial was performed from June 2012 to July in Arak
186 female students, who were randomly assigned to the intervention and control groups. After obtaining
written informed consents from the participants, they were asked to complete the Test Anxiety Scale once
at baseline and once following the intervention. The students in the intervention group received
aromatherapy for seven nights. For this purpose, five to six drops of lavender were poured on a cotton
ball and held at a 5 cm distance from the nose for 5 min. On the other hand, no intervention was applied
for the control group. For statistical analysis, t-test and Chi-square test were performed.
Results: The findings showed no significant difference between the intervention and control groups in
terms of mild [30 (49.2%)and 25 (58.1%), respectively], moderate[18 (29.5%) and15 (35.7%),
respectively], or severe [2 (3.3%) and 1 (2.4%), respectively] anxiety (P=0.232). However, the number of
anxiety-free students was higher in the intervention group (n=11), compared to the controls
Conclusion: The obtained findings showed that aromatherapy with lavender could increase the number of
anxiety-free students. However, no significant difference was found in the severity of test anxiety
between the two groups.
