Peritoneal Dialysis and Central Venous Catheters

1. The concerns I have over reliability and validity are related to the trustworthiness of the study, and a way to overcome any concerns is to ensure that both reliability and validity are credible and confirmable. Reliability data will be collected with a large sample of patients and health care workers over at least two sites, one for peritoneal dialysis and one for CVC/AVF (Coventry et al., 2021). Validity assessment will be done in participation with health care workers who work directly with patients with CVD, addressing areas for possible improvements or modifications (Coventry et al., 2021). Recommendations for improving reliability and validity depend on the study; however, it is important to ensure that data is stable and consistent (Souza et al., 2017). Reliability and validity depend on each other and cannot be assessed separately.

2. For research purposes, non-probability sampling methods are anticipated to be used with a sample of at least 500 patients with CVD. Non-probability sampling methods, such as quota sampling, are appropriate for the research proposal because there needs to be a specific sample of patients with CVD without random selection (Berndt, 2020). Whether probability or non-probability sampling methods are appropriate depends on research. For example, if research does not specify criteria and everyone has an equal chance of being selected, simple random sampling would be appropriate (Berndt, 2020). If research has to include every Nth person, systematic sampling would be more appropriate (Berndt, 2020). On the other hand, if research needs voluntary participants but with specified criteria, it would be more appropriate to approach self-selection sampling (Berndt, 2020). In order to choose an appropriate sampling method, the researcher should consider the type of research, type of inference, basic for selection.
