Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

• Anxiety

  Measured using the Beck Anxiety Inventory (BAI) at baseline, week 2, and week 4. Higher scores indicate higher anxiety.

  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.

  Baseline, Week 2, Week 4

Secondary Outcomes (1)

• Sleep quality

  Baseline, Week 2, Week 4

Study Arms (2)

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.

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.

Interventions

Lavender OTHER

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 Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: TRIPLE
• Who Masked: PARTICIPANT, INVESTIGATOR, OUTCOMES ASSESSOR
• Masking Details: Participants, the interventionist, and the statistician are blinded. Patients are randomly assigned using simple randomization (odd-numbered to one group, even-numbered to the other). Group allocation (lavender oil or control) is determined by an independent nurse. Separate consent forms and coded data entry (groups as 1 and 2) ensure blinding is maintained.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Asist. Prof. Dr.

Model Details: 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.
