The Effect of Music on Nonstress Test and Pregnant Women's Satisfaction: Randomized Controlled Study
The Effect of Music on Nonstress Test and Pregnant Women's Satisfaction: Randomized Controlled Study
This study was conducted as a randomized controlled trial. This study was conducted to determine the effect of music on nonstress test and pregnant woman's satisfaction. The study was conducted with pregnant women who applied for non-stress testing at a hospital in Samsun, Turkey, between September 2021 and September 2022. Pregnant women who met the research criteria were divided into two groups: physical and control groups. The research was completed experimentally with a total of 111 pregnant women, 56 experimental and 55 control. The researcher had a face-to-face interview with all the pregnant women and filled out the "Pregnant Introduction Form". Then, the vital signs of the pregnant women were taken and the pregnant women were placed in the left side-lying position. Fundus height, situs and position were determined using Leopold maneuvers. During the non-stress test shooting, the music group was allowed to listen to music for at least 20 minutes during the NST period. No intervention was made to the control group. After the non-stress test is completed, the "Satisfaction Evaluation Scale" is taken by the pregnant woman herself. The "Nonstress Test Monitoring Form" was filled out by the researcher through notification. The data of the study were evaluated using the Statistical Package for the Social Sciences program. All data were first analyzed by Kolmogorov-Smirnov for conformity with normal distribution. were evaluated and then analyzed according to their suitability for normal distribution. For descriptive statistics, percentage across the board, arithmetic mean±standard deviation for those with normal distribution, median and minimum-maximum values for those that did not fit were used. In the analysis of the data, student t test and ANOVA test were used for those that were suitable for normal distribution, and Mann-Whitney U and Kruskal Wallis tests were used for those that were not suitable for normal distribution. Type 1 error level was taken as 0.05.
Aim: To determine the effect of music on non-stress test and pregnant woman's satisfaction.
Hypotheses:
H01: There is a difference between the non-stress test results of pregnant women who received music and the control group pregnant women.
H02: There is no difference between the satisfaction levels of pregnant women who received music and the control group pregnant women.
Method: The research was conducted in the non-stress test room in the gynecology outpatient clinic of a hospital in Samsun. The population of the research consisted of pregnant women who applied to the non-stress test room for non-stress test examination after having a pregnancy follow-up at the gynecology outpatient clinic of this hospital.
Sample Size: The sample number of the study was calculated according to the power analysis performed with the G Power 3.1.9.2 program. Accordingly, for the use of t-test in independent groups, effect size: 0.5, alpha = 0.05 and power: 0.80 were calculated and a total of at least 51 pregnant women were included in each group. 102 pregnant women were calculated. In order to increase the analysis power of the research, the sample size was completed with 111 pregnant women (music group: 56, control group: 55). The pregnant women in the music group and the control group were stratified according to age and the groups were distributed homogeneously.
provided. Which group the participants would be in was determined by full randomization technique on the website www.randomizer.org.
Data Collection Tools The data of the study were collected with the Pregnant Introduction Form, non-stress Monitoring Form and Satisfaction Evaluation Scale created by the researcher.
Pregnant Introduction Form: This form was developed by the researcher. It consists of questions including socio-demographic and obstetric characteristics and vital signs of pregnant women.
Nonstress Test Monitoring Form: This form was developed by the researcher and is the form preferred by pregnant women during non-stress examination.
It consists of questions about the music genre, thoughts about non-stress, and findings about non-stress for the researcher to evaluate the non-stress result. It consists of a total of 15 questions that determine pregnant women's thoughts about non-stress and include findings regarding non-stress. Non-stress results of the pregnant women were evaluated by the researcher. If there was any doubt in the evaluation, it was re-evaluated with the gynecologist.
Reactive non-stress; It was defined as the presence of at least two fetal movements within a 20-minute period, parallel to the movements, accelerations in the fetal heart rate that were more than 15 beats above the basal heart rate and lasted more than 15 seconds.
Nonreactive non-stress; It was defined as the absence of fetal movements or the presence of fetal movements, but accelerations of less than 15 beats and lasting less than 15 seconds within a 20-minute period.
Satisfaction Evaluation Scale: This scale was adapted by researchers similar to the "Visual Analog Scale (VAS)" usage principles. One end of VAS is "very good" and the other end is "very bad".
It is a scale that is evaluated by individuals by making markings on a horizontal or vertical line of 10 cm or 100 mm. This line may be just a straight line, or it may be divided at equal intervals or have descriptive words placed on the line. VAS is used to make some values that cannot be measured numerically measurable. In this scale, in order to evaluate whether the pregnant women in the music group were satisfied with the music during the non-stress shooting, the numbers between 0 and 10 were placed on a vertical line, where they would indicate with a cross (X) the point corresponding to their satisfaction with the procedure as a result of the application. In the scale, 0 points indicate "I was not satisfied at all" with the application result, and 10 points indicate "I was very satisfied" with the application result.
Collection of Data After obtaining the necessary ethics committee and institutional permission to conduct the study, the institution was visited and the pregnant women who came for non-stress examination were met. Pregnant women who meet the research criteria during working hours An explanation will be made about the purpose of the research, its content and the methods to be applied, and those who want to participate in the study are determined. Then, a random number generation program determines which group the pregnant women will be in.
They were divided into two groups: music and control groups using the "Research Randomizer". Thus, each pregnant woman's number and group number were determined and recorded. Oral and written consent of those who accepted the research Their consent was taken. The researcher had a face-to-face interview with all the pregnant women and filled out the "Pregnant Introduction Form". Then, the vital signs of the pregnant women will be taken and the pregnant women will be placed in the left side-lying position.
Fundus height, situs and position were determined using Leopold maneuvers. During the NST shooting, the music group was allowed to listen to music for at least 20 minutes during the non-stress. In the control group, no intervention was given.
It will not be done. After the nonstress test was completed, the "Satisfaction Evaluation Scale" was filled out by the pregnant woman through self-report, and the "Nonstress Test Follow-up Form" was filled out by the researcher. The interview number specified in the survey form will be written in the upper right corner of the Nonstress Test paper, and a copy of the nonstress test paper was taken with the Adobe Scan scanner installed on the smartphone device.
Statistical analysis The data of the study were evaluated using the Statistical Package for the Social Sciences (SPSS) program. All data were first evaluated with Kolmogorov-Smirnov for suitability for normal distribution, and then analyzed according to their suitability for normal distribution. For descriptive statistics, percentage across the board, arithmetic mean±standard deviation for those with normal distribution, median and minimum-maximum values for those that did not fit were used. In the analysis of the data, student t test and ANOVA test were used for those suitable for normal distribution, Mann-Whitney U and Kruskal test for those not suitable for normal distribution.
Wallis test was used. Type 1 error level was taken as 0.05.
