The Effect of Watching Cat Videos on Maternal Stress and Fetal Well-being: A Single-Blind Randomized Controlled Trial

Pregnancy is a period in which women are physiologically and psychologically vulnerable, and the stress experienced can affect both maternal mental health and fetal well-being. The non-stress test (NST), used to assess fetal health in the final weeks of pregnancy, can cause anxiety in some women because it requires the mother to remain supine and immobile for extended periods. Prolonged testing or non-reactive results can also increase this stress. Therefore, simple methods are needed to reduce stress during NST. Humorous and cute content, especially animal videos, is known to promote positive emotions and psychological relaxation. This study evaluated the effects of watching cat videos during NST on stress levels and fetal physiological parameters in primiparous pregnant women.

Detailed Description

Pregnancy is a sensitive period during which women experience a variety of changes, both physiologically and psychologically. Stress factors encountered during this period can negatively impact the mother's mental health and fetal well-being. Non-stress testing (NST) is a non-invasive screening method frequently performed in the final weeks of pregnancy to assess fetal health. However, during the NST, the mother lies motionless in a supine position for approximately 20 minutes, during which time she attempts to obtain sufficient data on the baby's heart rate and movements, which can cause stress and anxiety in some women. A prolonged duration or a non-reactive test result can be a cause for concern. Therefore, simple and effective methods are needed to reduce maternal stress during the NST. Humorous and cute content, especially animal videos, are known to evoke positive emotions and provide psychological relief in viewers. The purpose of this study was to evaluate the effect of watching a cat video during the NST procedure on stress parameters and fetal physiological parameters in primiparous pregnant women.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention group
Behavioral: Group watching cat videos
The cat video, which will be shown to pregnant women as part of the study, will be implemented as an intervention to reduce participants' stress levels during the NST. The NST session takes approximately 20 minutes, and the video will be played for this duration. The content of the video will be carefully selected to create a relaxing and entertaining effect on the audience. Participants will begin watching the video immediately after connecting to the NST device and will continue to watch throughout the NST. This process aims to calm participants, reduce stress levels, and promote overall relaxation.
Experimental: Control Group
Participants randomly assigned to the control group will also rest in a private room for 10 minutes, after which all initial measurements will be taken. A routine NST will then be performed.
Behavioral: Non-Video Watching Group
Participants randomly assigned to the control group will also rest for 10 minutes in a private room and all initial measurements will be taken.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The effect of watching cat videos on stress parameters in pregnant women
Time Frame: This procedure will be performed during the NST for pregnant women experiencing their first pregnancy and who are between weeks 34 and 40 of gestation.
Participants randomly assigned to the intervention group will be taken to a designated room determined by the researcher before the NST for their initial measurements. The "Pregnant Women Demographic Information Form" and the "State-Trait Anxiety Inventory (STAI Form TX-1)" will be administered. Blood pressure, heart rate, oxygen saturation, cortisol, and ACTH levels will be measured. All physiological measurements except ACTH and cortisol will be performed at three time points: before the NST (2 minutes before start), in the middle of the NST (approximately 10 minutes), and after the NST (2 minutes after completion). The "State-Trait Anxiety Inventory (STAI Form TX-1)" will also be administered after the NST. Following the NST, satisfaction levels will also be assessed using the Visual Analog Scale (VAS).
This procedure will be performed during the NST for pregnant women experiencing their first pregnancy and who are between weeks 34 and 40 of gestation.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The effect of watching cat videos on physiological parameters of the fetus
Time Frame: This procedure will be performed during the NST for pregnant women experiencing their first pregnancy and who are between weeks 34 and 40 of gestation.
Participants randomly assigned to the intervention group will be taken to a designated room determined by the researcher before the NST for their initial measurements. The fetal heart rate and reactivity will be assessed using the NST device. To determine fetal well-being, the Non-Stress Test-Baseline, Non-Stress Test-Variability, Non-Stress Test-Acceleration, and Non-Stress Test-Deceleration numbers will be examined.
This procedure will be performed during the NST for pregnant women experiencing their first pregnancy and who are between weeks 34 and 40 of gestation.
