The Effects of Using Virtual Reality Glasses During the Non-Stress Test

Study Overview
=================
Brief Summary
-----------------
The aim of this study to determine the effect of virtual reality glasses use on anxiety, stress and fetal well-being during the non-stress test. Personal information form was used as data collection form, Revised Prenatal Distress Questionnaire (NUPDQ-17 Item Version) was used to assess distress, State-Trait Anxiety Inventory (STAI) was used to assessanxiety.

Detailed Description
-----------------
Material and Method This research was conducted between between October 2021 and February 2022 in Fethi Sekin City Hospital. When power analysis was performed, the sample size was calculated to be at least 71 women for each group (71 experiments, 71 controls). During the NST procedures, VR glasses were given to the participants in the experimental group by the researcher for the intervention. Data collection form for experimental and control groups before the NST procedures; Revised Prenatal Distress Questionnaire (NUPDQ-17 Item Version) and State-Trait Anxiety Inventory (STAI) were applied two times before and after NST procedure. After the NST procedures, both groups were re-administered. Descriptive statistics and independent t-test were used for data analysis.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Anxiety scores | StateTrait Anxiety Scale (STAI The highest score from the scale is 80, the lowest score is 20. Higher STAI-I scores indicate higher state anxiety levels | NST involves 20 minutes of monitoring the fetal heart rate (FHR) | 
| Distress scores | Revised Prenatal Distress Questionnaire (NUPDQ-17 Item Version): The highest score from the scale is 34, the lowest score is 0. Higher scores indicate higher levels of perceived prenatal distress in the respondent | NST involves 20 minutes of monitoring the fetal heart rate (FHR) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Fetal Well-Being scores | NST Registration Form: In the interpretations, the baseline FHR was accepted as 110-160 bpm, variability in a reactive NST was accepted as an FHR of 6-25 bpm, and acceleration was accepted as an elevation in the baseline FHR by at least 15 bpm for at least 15 s. Additionally, deceleration was accepted as a 15-20 bpm drop in comparison to the baseline FHR, and a reactive NST was defined as a result where two or more accelerations peaked at least 15 bpm above the baseline point, each acceleration lasted 15 s or longer, and all these conditions were met within 20 min from the start of the test. A nonreactive NST was defined as the absence of at least two accelerations lasting at least 15 s on the NST tracing paper within 20 min from the start of the test | NST involves 20 minutes of monitoring the fetal heart rate (FHR) |
