Official title
Effect of Light Color on Stress, Anxiety, and Psychological Well-being During Nonstress Test in Pregnant Women at Risk: A Randomized Placebo-controlled Study
Overview
Purpose of the research: To determine the effect of light color on stress, anxiety, and psychological well-being during the Nonstress Test in at-risk pregnant women. This research was planned as a single-blind randomized controlled experimental type study by comparing separate groups in the form of experiment-placebo control. Data will be collected with the Introductory Information Form, Psychological Well-being Scale, Perceived Stress Scale (PSS/PSS-14), State Trait Anxiety Inventory (STAI). The NST device is used to follow up pregnant women in the last 3 months of pregnancy, first monthly, then every two weeks and once a week. In other words, the procedure is routinely performed on every pregnant woman who comes for control. It is a device that shows the well-being of the baby and whether the mother has contractions. It is attached to the pregnant woman's abdominal area and does not cause any harm. It is not an invasive procedure. Pregnant women in the last 3 months of pregnancy who come to have NST for follow-up will be randomly selected and divided into 2 groups. A lamp with adjustable light level with Unit Unit Ut-383 Mini Luxmeter (Light Meter) will be placed in the intervention and control groups and the light level of the lamp will be adjusted to 100 lux. NST will be taken under cold (bluish white) light for the control group and under medium warm white (daylight white) light for the intervention group. Pre-test before the application and post-test after the application will be applied. The application is an invasive application that will not disturb the pregnant woman.
