Quantitative Critique: Relaxation Response in Nurses
This paper presents a quantitative critique of Calisi's (2017) pilot study examining the effects of the relaxation response (RR) technique — originally developed by Dr. Herbert Benson — on nurses' anxiety, depression, well-being, work-related stress, and confidence to teach the technique to patients. The critique evaluates the study's background, literature review, research design, sampling methods, data collection instruments, statistical analyses, results, ethical considerations, strengths, and limitations. Key findings indicate that while the RR technique did not produce statistically significant reductions in work-related stress, nurses in the intervention group did gain confidence in teaching the technique. The paper concludes with recommendations for future large-scale research.

What makes this paper effective
- The paper follows a clear, methodical critique structure — moving from background and methods through results, ethics, and evaluation — making it easy to assess each component of the source study in isolation.
- The writer accurately distinguishes between primary and secondary hypotheses and ties the statistical outcomes back to each hypothesis, demonstrating an understanding of how quantitative studies are evaluated.
- The identification of both strengths (ethical consent, relevance to patient care) and limitations (small sample size, single nurse specialty) shows balanced critical analysis rather than one-sided commentary.
Key academic technique demonstrated
The paper demonstrates systematic quantitative critique: the student identifies the research design, sampling method, statistical tests used (paired-sample t-tests, repeated measures), and outcome instruments (STAI, Semantic Differential Scale), then evaluates their appropriateness for the research question. This approach — checking methodological fit rather than simply summarizing findings — is the hallmark of a well-executed research critique at the undergraduate level.
Structure breakdown
The paper opens with an orientation to the study's three research questions and dual hypotheses, then moves through background and literature review, methods, results, ethics, and evaluation before closing with a conclusion and future-research recommendation. Each section corresponds to a standard component of a quantitative research critique framework, making the organizational logic transparent and easy to follow.
Introduction and Research Questions
This paper presents a quantitative research critique of the article "The Effects of the Relaxation Response on Nurses' Level of Anxiety, Depression, Well-Being, Work-Related Stress, and Confidence to Teach Patients," by Calisi (2017). There are three research questions in this study: how to teach the relaxation response (RR) technique — a method formulated by Dr. Herbert Benson — how to measure the effects of RR on nurses' anxiety levels and work-related stress, and how to investigate the confidence of those nurses to teach the same technique to their patients.
The primary hypothesis being tested was that nurses would experience an improvement in stress levels and a reduction in work-related stress. The secondary hypothesis was that nurses would gain confidence in teaching the RR technique, having learned and practiced it themselves.
Background and Literature Review
The background section begins by defining burnout and compassion fatigue, the most common causes of exhaustion among nurses. The current workload and increased demand for patient care lead to physical, mental, and emotional stress, causing a decline in nurses' own well-being — a state referred to as burnout or compassion fatigue (Calisi, 2017). Fluctuating patient care demands and longer working hours force nurses to work beyond their normal routines, making them more fatigued. Constant exposure to stress-inducing environments, as is characteristic of the nursing profession, causes chronic stress that leads to burnout (Roberts & Grubb, 2014). Such chronic stress can affect nurses' behaviors in the form of extreme sensitization (Wilson, 2013). Although nurses must show compassion to patients despite their own work-related stress, mental and physical fatigue prevents them from performing at their best. Workloads push nurses to skip breaks in order to attend to patients. The persistent stress associated with long working hours, double shifts, and night duties poses a significant risk of fatigue and burnout, and can even compromise the quality of patient care (Stimpfel, Sloane, & Aiken, 2012).
The background is supported by various scholarly studies noting that vitality is necessary for performing at full potential. Vitality is defined as a sense of liveliness, buoyancy, and overall healthiness. Nurses with high levels of vitality demonstrate commitment and a sense of purpose in their daily work and service to patients. Research has shown that nurses need self-compassion in order to find meaningfulness in their duties and motivation in their work, which in turn leads to improved patient satisfaction.
The literature review also discusses wellness strategies for reducing nurses' stress in detail. Several techniques — including yoga, tai chi, guided imagery, and the relaxation response (RR) — were considered for measuring their effectiveness. These techniques aim to calm physical and mental stress by slowing down the mind and invigorating the body and spirit. The literature suggests that teaching nurses this relaxation method would produce a morale boost in their daily practice, with a direct positive effect on patient care.
The relaxation response technique was first developed by Dr. Herbert Benson and primarily involves diaphragmatic breathing combined with sustained mental concentration. This practice interrupts the flow of everyday exhausting thoughts and should be performed for 10 to 20 minutes daily. It has also been shown to help alleviate related conditions such as hypertension, insomnia, depression, and phobias.
There does not appear to be any bias in the selection of studies for the literature review. Searching keywords such as nurse burnout, fatigue, stress reduction techniques, and patient satisfaction yields an extensive body of literature consistently indicating that stress reduction methods have been greatly beneficial in lowering nurses' stress levels and improving patient care outcomes.
Summary of Methods
The selected study was a pilot study, which serves as an initial step before conducting a full, large-scale study (In, 2017). A pilot study functions as a small trial of the main trial, used to test the validity of the research design and experimental methods. As a result, an experimental approach was chosen for this pilot study.
The study is not non-experimental and therefore uses SPSS analysis with means and standard deviations for the study variables. A random sampling method was used, as participants were selected without following any systematic or stratified pattern. Participation was voluntary; registered nurses from three cardiac units of a hospital were recruited. Two groups were formed: a wait-list control group and an intervention group. Pre- and post-self-report assessments were completed by nurses who received the RR technique for 10–20 minutes, twice per day, over eight weeks. The control group did not receive the 45-minute training in the RR technique during the study period; however, they were offered the training after the study's conclusion.
The researcher used validated instruments for data collection, as the data needed to determine whether the RR technique produced positive effects over the eight-week trial. Independent sample t-tests were conducted to compare the study variables at baseline. Repeated measures tests were conducted so that paired-sample t-tests could yield reliable results for reviewing the effect of the RR intervention and its related measures over time. These tests were carried out both within and between the study groups to ensure reliability.
Conclusion
The selected article evaluated the effects of the RR method on reducing stress, anxiety, depression, burnout, and compassion fatigue among nurses, and whether nurses gain confidence in teaching the technique to their patients after receiving training. The results showed that the RR technique did not produce statistically significant reductions in work-related stress. However, it did provide nurses with increased confidence to teach the technique to their patients — the only statistically significant positive finding from the study, a result attributable in part to the sample size limitations inherent in pilot research.
A recommendation for a future follow-up study would be to examine the importance of educating nurses during their graduate programs about self-compassion and self-care, and to assess how such education might support stress reduction in professional practice thereafter.
