The 2016 study by Labrague and McEnroe-Petitte researches the influence of music on anxiety levels during various medical procedures on women. The study used purposive sampling to focus on female patients within a gynecologic setting (Labrague & McEnroe-Petitte, 2016). The researchers chose the purposive method because they wanted to investigate the research question only among a specific part of the population (Setia, 2016). In this case, the subjects had to have no difficulties in hearing, be eighteen years of age or more, sign the informed consent form, and undergo gynecologic surgery. The strengths of such sampling include the clarity of all the proposed criteria. Moreover, the sampling matches both groups and similar studies on the topic, which helps with comparability. Overall, the sample is relatively representative, but the main weakness is that it only focuses on one hospital and region, which makes the study more limited.
Furthermore, the study results show that women allocated in the experimental group had lower State Trait Anxiety Inventory (STAI), systolic, diastolic, BP, and P rate than the control group. However, no statistically significant difference was discovered in the respiratory rate (RR) within the sample (Labrague & McEnroe-Petitte, 2016). This study presents empirical data to encourage the use of music to reduce anxiety in women receiving gynecologic surgery. Thus, the findings can be considered valid and reliable because of the similarities between the two groups.
Lastly, the scholars could not employ random sampling, as there are multiple qualifiers crucial to the research, such as gender and specific health conditions. However, the researchers could have expanded their experiment to other hospitals to make the study more inclusive. Lastly, the study’s sample could have been affected by the study protocol, which could have influenced the subjects’ feelings and emotions, as these aspects were self-reported.
