Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

This study aims to evaluate the effects of lavender oil inhalation on anxiety, sleep quality, and blood pressure in patients with primary hypertension. It is designed as a double-blind randomized controlled trial. Patients presenting to the Cardiology Outpatient Clinic of Ardahan State Hospital will be recruited for the study. Participants will be randomly assigned to an experimental group, which will receive 12 lavender oil inhalations three times a week for one month, or to a control group, which will continue routine care. Data will be collected using the Hypertension Diagnostic Form, Beck Anxiety Inventory, and Pittsburgh Sleep Quality Index. The study will assess whether lavender oil inhalation affects anxiety, sleep quality, and blood pressure in this population. Statistical analyses will be conducted to compare outcomes between the experimental and control groups.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

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.

Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

experimental group

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.

Group Type EXPERIMENTAL

Lavender

Intervention Type 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.

Routine care only

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.
