For Each Of The Following Studies Study One Study Two State A Rea

For each of the following studies (Study One & Study Two): state a reasonable research question based on the study description, identify the Independent variable(s), Dependent variable and its Level of measurement, and one Controlled variable. You are given an example of the information being sought. Study One (10 points) You are interested in look at the effects of strengthening exercise in adults with Down’s syndrome. You randomly select twenty subjects (age range 19 – 35 years) from an adult workshop group. You measure the strength of the elbow flexors in pounds using a dynamometer prior to the start of an eight-week resistance training program. At the end of the eight weeks, you again test the strength of the elbow flexors. Research Question: Does the resistance training program improve the strength of the elbow flexors or it does not have an effect on the subjects? Independent Variable (s): The Independent Variable is the comparison that is in the study. Which it is the strength of the elbow flexors that could be improved on remained the same. Dependent Variable (s): The dependent Variable it is the outcome of the measure. Mainly establishing if the resistance training has any effect if the strength of the elbow flexors. Level of Measurement: Ratio Controlled Variable: There are various controlled Variables, which are controlled by the researcher. There is the age (19 to 35 years) of the subjects and the length of the strengthening exercise (8 weeks) Study Two (10 points) You are interested in evaluating the effectiveness of three different education programs on caffeine consumption in young adults, age 18 – 24 years, who report that they drink at least one cup of coffee per day. You have a volunteer group of 30 subjects, and randomly assign each to one of the three education programs. Immediately after completion of the study, you determine how many have changed their consumption of caffeine (measured as change/no change). You re-interview the participants six months after completion of the program to determine if there has been a change in drinking habits. Research Question: Do the three educational program of drinking caffeine change the drinking habits of the individuals? Independent Variable (s): The Independent Variable it is the caffeine consumption that is aimed which is the basis of comparison. It assumes two values drinking caffeine and reduced drinking caffeine. Dependent Variable (s): These are the outcomes of the measure which is basically the 6 months in which the educational programs are supposed to change the drinking habits of the subjects. Level of Measurement: Ratio Controlled Variable: there are various controlled variable which are controlled by the researcher. The age of the subjects (18-24), Caffeine Consumption (1 cup of coffee/day), the number of subjects (30 subjects) and time period (6 months). Research Question What is the impact of the shortages in personal protective equipment (PPEs) on the safety of the patients in this period of a fight against coronavirus? This research is aimed at looking at how the safety of the patients and healthcare providers is compromised during this period of coronavirus pandemic as a result of the shortages of the PPEs. PPEs are playing an important role in ensuring that healthcare providers are protected from the fluids or blood when they sneeze or cough and during the treatment. Healthcare providers are always interacting with the patients and this is exposing to being infected by the coronavirus if they are not protected using the PPEs (Livingston & Berkwits, 2020). The guidelines produced by the CDC gives some recommendations to be followed when dealing with the crisis situation. Covid-19 is a pandemic condition and the shortages of the PPEs appear to be a crisis that is emerging in the entire world. Therefore, the CDC recommends the use of the shield with no mask when dealing with the current situation when there is a lack of PPEs. These proposed shields are not protective and effective as PPES and this, therefore, implies that healthcare providers are highly exposed to the infection (Liu, et al., 2020). When healthcare providers are infected, it implies that patients who are free from the virus or have yet been diagnosed with the coronavirus are at high risk of being infected by the virus. The use of the PPEs is meant to protect the healthcare providers and to break the chain of coronavirus spread from the healthcare providers to the patients and to the families when these patients are discharged from the facilities. Failure to provided adequate PPEs implies that the risk of patients being infected is higher (Livingston & Berkwits, 2020). The spread of the disease is also caused by the workload as a result of the rising number of patients being admitted to the facility. One of the strategies being used by healthcare facilities to deal with the issue of shortages in the PPEs is the reduction in the number of healthcare providers in each day. This is done to ensure that the number of PPEs being used by healthcare providers is reduced. Nevertheless, this strategy is also presenting some adverse effects which make the situation to be worse for the healthcare providers. Making some healthcare providers stay at home implies that only a few are left to provide healthcare services to the patients. This increases the number of workloads for these healthcare providers. There are high cases of medication errors due to fatigue and it makes it hard for these healthcare providers to confirm whether the services being provided to the patients are of high quality or not (Liu, et al., 2020). Whether the study will take a qualitative or quantitative approach The study will take a qualitative approach to help in responding to the questions raised in the research. This approach is important since it will allow the process of arriving at the solutions to respond to the raised question. It will help in the collection of adequate data without going to the field during this pandemic period. The information will be gathered through interviewing a few of the selected healthcare providers. Their response will provide a basis for the situation of the PPEs shortages and how it is affecting their delivery of services to the healthcare providers.

The provided prompts involve analyzing three distinct research scenarios to identify their respective research questions, independent and dependent variables, and controlled variables. This exercise emphasizes understanding foundational research components and how they relate to study design. Through examining these examples, the importance of clearly defining variables to draw valid conclusions about cause-and-effect relationships is highlighted.

In the first scenario, the focus is on evaluating the effect of resistance training on elbow flexor strength among adults with Down’s syndrome. The research question centers on whether an eight-week resistance program can improve muscle strength. The independent variable here is the resistance training program itself, which is manipulated by the researcher to observe its effects. The dependent variable is the strength of the elbow flexors, measured in pounds using a dynamometer—a ratio level of measurement, providing continuous data that can be precisely quantified. A key controlled variable is the age of participants, maintained within 19-35 years, alongside the duration of training to ensure consistency across subjects. This careful control enables attributing observed changes specifically to the intervention.

In the second scenario, the research investigates the efficacy of three different educational programs aimed at altering caffeine consumption behaviors among young adults. The research question examines whether these interventions lead to significant behavioral changes over a six-month period. Here, the independent variable comprises the type of educational program assigned to each participant, which could influence their caffeine intake. The dependent variable is the change in caffeine consumption, recorded as a binary outcome: changed or no change. The ratio level of measurement captures the variation in caffeine intake amounts, though in this case, the primary focus is on the change status. Controlled variables include age, initial caffeine consumption levels, the total number of participants, and the follow-up period, which are kept consistent to reduce confounding influences.

The third scenario explores the impact of PPE shortages during the COVID-19 pandemic on patient safety and healthcare worker well-being. The research question asks how PPE shortages influence safety outcomes amidst a crisis. Since this study aims to understand perceptions and experiences, it adopts a qualitative approach involving interviews with healthcare providers. Although not explicitly structured with independent and dependent variables as in quantitative studies, key variables include PPE availability (independent variable) and safety or error rates (dependent variables). Controlled variables are less defined but may include the healthcare setting, provider workload, and demographic characteristics, all of which are maintained to reduce extraneous variability.

Overall, these examples underscore the importance of precise variable identification in designing robust studies. Quantitative studies rely on clear levels of measurement and control to establish causality, while qualitative research emphasizes understanding experiential factors. Recognizing these components enhances the validity and reliability of research findings, facilitating meaningful contributions to health sciences and practice.
