Effect of Lavandula Angustifolia Extract to Prevent Test Anxiety (A Study on Students at Two Time Intervals)

Background and Aim: Test anxiety is a category with which most students are familiar; in some cases, it reduces their academic performance and has a negative effect on their health. Lavandula angustifolia is a plant whose effect on reducing anxiety and stress and other psychiatric disorders has been studied. In this research, its extract has been used to prevent students' test anxiety at two-time intervals.

Research method: This research was a clinical trial study on 45 first-year high school students. All students completed the TAI Anxiety Test Questionnaire and then randomly were divided into three groups: control, short-term consumption and long-term consumption. The fresh extract of Lavandula angustifolia (prepared by hydrodistillation) was provided to the second and third groups to be used as edible in two periods of three days and twenty days at the time of examinations. The students of the two experimental groups completed the TAI questionnaire again after the end of the period. The answer sheets were analyzed using covariance analysis.

Results: The analysis of the findings showed that there was a significant difference between the scores of the control group and the two groups of "long-term consumption" and "short-term consumption" (P <0.05), but between the two experimental groups (in two short-term and long-term intervals) no significant difference exists in the change of this index by students (P> 0.05).

Conclusion: According to the findings, it can be concluded that Lavandula Angustifolia Extract is effective in reducing the test anxiety, but the duration of consumption (in the three-day and twenty-day intervals) has no effect on this reduction.
