About this study
Official title: Effects of Lavender Oil Inhalation Applied to Patients With Primary Hypertension on Anxiety, Sleep Quality and Blood Pressure
This study aims to determine the effects of lavender oil inhalation on anxiety, sleep quality, and blood pressure in patients with primary hypertension. The study is designed as a double-blind randomized controlled trial. The study population consists of patients presenting to the Cardiology Outpatient Clinic of Ardahan State Hospital. Participants are randomly assigned to an experimental group, which will receive a total of 12 lavender oil inhalations three times a week for one month, or to a control group, which will continue routine treatment and care. Data will be collected using the Hypertension Diagnostic Form, Beck Anxiety Inventory, and Pittsburgh Sleep Quality Index. Statistical analyses will be conducted to compare outcomes between the experimental and control groups.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
LavenderOther
Participants receive lavender oil inhalation three times per week for one month (total of 12 sessions) using a standardized diffuser. This intervention is provided in addition to routine care for primary hypertension. Outcomes measured include anxiety, sleep quality, and blood pressure before and after the intervention.
| Study group | Role | What they receive |
|---|---|---|
| experimental group | Experimental | Participants receive lavender oil inhalation three times per week for one month (total of 12 sessions) in addition to routine care for primary hypertension. Anxiety, sleep quality, and blood pressure are assessed before and after the intervention. Receives: Other: Lavender |
| Routine care only | No intervention | Participants in the control group continue their routine care and treatment for primary hypertension without receiving lavender oil inhalation. Anxiety, sleep quality, and blood pressure are assessed before and after the study period. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Anxiety
Measured using the Beck Anxiety Inventory (BAI) at baseline, week 2, and week 4. Higher scores indicate higher anxiety.
Measured: Baseline, Week 2, Week 4
Blood Pressure
Measured using the Hypertension Diagnostic Form at baseline, week 2, and week 4. Includes systolic and diastolic measurements.
Measured: Baseline, Week 2, Week 4
Secondary outcomes (1)
Sleep quality
Measured using the Pittsburgh Sleep Quality Index (PSQI) at baseline, week 2, and week 4. Higher scores indicate poorer sleep quality
Measured: Baseline, Week 2, Week 4

- Model description
- The study uses a parallel assignment design with two groups: an experimental group receiving lavender oil inhalation and a control group receiving routine care. Participants are randomly assigned to one of the two groups. The study is double-blinded: neither the participants, the researchers administering the intervention, nor the statisticians analyzing the data know group assignments. Outcomes (anxiety, sleep quality, and blood pressure) are measured before and after the one-month intervention period.
