Credibility and transferability
Participants are randomly selected based on certain criteria mentioned previously in this research proposal to enhance internal validity. Preliminary to participation, the researcher will ask for informed consent from each participant. Inter-response consistency is created by using standardized questionnaires. Furthermore, the research will be critically peer reviewed by supervisors. Further, an audit trail will be filled out during the research in order to improve transferability. Audit trails refer to the act of maintaining data regarding decisions related to the study. For example, in case changes are made to the original research proposal, this will be reported in the audit trail. In addition, documentation

Firstly, a quantitative research design will be applied, therefore potentially missing valuable qualitative information. Secondly, the obtained data will be analyzed using a mixed-method approach. Certain approximations have to be used in order to estimate some parameters. As a result, conclusions are partially drawn on assumptions, increasing the probability of biases.45 Thirdly, participants have to be willing to participate in this study and have to fulfill certain criteria to be eligible to participate, leading to a selective population. Therefore, the sample may not be a true random sample and limits the geographical scope of participants. This might eventually cause a selection bias. Fourthly, the likelihood of missing data. This may lead to problems in data analysis and misinterpretation of the results. Reporting of missing data over time will be done in order to interpret the data adequately. Fifthly, reliability and validity of tools. Although, the included tools are validated and considered to be reliable and clinically relevant according to a number of studies.46–48 Finally, time constraint limits the scope of the …show more content…
The following paragraphs discuss the PROMs that will be used in this study more in depth. In addition, a number of neurocognitive tests have been selected to comprehensively evaluate the patients’ cognitive status by testing certain neurologic domains. CRFs are collected for each patient prior to the onset of the treatment and during follow-up. Examples of the PROMs, neuro-cognitive tests and CRFs can be found in the appendix. The tests are physically non-invasive and consist of paper and pencil
All of the participants were treated and there was no omitted information. The participants also did not abandon the study. The problems of missing values were evaluated and adequately addressed. The limitation of the study includes gender and sample size. The researchers discussed the weaknesses with solutions for future studies. The researchers recommend replicating this study using a larger sample size that includes females. They consider that these changes would increase the significance of the results. The findings are discussed and interpreted.
To ensure the proposed study is academically, professionally, and ethically sound, researchers shall complete a risk assessment on the proposed method (participants, materials and design) of the study. This risk assessment will form the basis of the application to Swinburne University’s Research Ethics Office for ethical review. This application will address the risks identified with the participants used, including recruitment and informed consent, as well as data and publication arrangements.
A research team leader will randomly select eligible participants and divided them into two equal groups, A and B. Group A pre-intervention and Group B post intervention. There are multiple delivery methods available for collection data such as interview (one-on-one, via telephone or in person), focus groups, and observation. The traditional method paper-and-pencil survey whose results are subsequently entered into a software program will be used as well as an online based collection to reducing the cost of data collection and encouraging voluntary participants. The data will be electronically downloaded directly to an Excel spreadsheet for analysis and minimizing data entry error or bias. There will be four different types
The researchers used purposive sample but did not give any explanation as to why this choice sampling was made. It is essential to describe the sampling process in a research where this facilitates the reader to distinguish any bias in the whole sampling process. In studies using participants, the process of how to select, access, inform and retain research participants requires considerable thought. Sampling is a key issue, because it is
This provides a guideline that ensures that researchers minimize the amount of risk a study may impose to a participant. When planning a study, it is also important that each of the participants are provided with a sense of security and not placed at a disadvantage. When participants enter into a study, a level of trust is established, and their identities and the information they provide must be protected and never be used against them or exploited for any reason.
Provided to each subject was a consent form to review and sign before their participation in this study. The researcher excluded any identifiable information from the data collection measures. Subjects received a number as they signed in for the information session. The researcher used these numbers to link the subjects to their surveys and their clinical assessments. Their numbers coordinated with the attendance form which was in the sole possession of the researcher. Institution
The lesson and case studies presented for evaluation was a great learning exercise. A better understanding of how to interpret data was gained. Also, weighing the clinical significance versus the statistical significance to show relevance is invaluable. All research is not quality research and one must be equipped to recognize bias, threats to validity and proper population representation. Moreover, critiquing the credibility of a study is essential to the health care advances.
In reviewing this article, this writer was able critique the study and the suitability that it can possess if applied to actual practice. An important factor on whether a study can be considered valuable is if it is transferable in other situation, that is, a study's results should also be reflective if duplicated on other samples (Polit & Beck, 2006). Thus, the statistical power, internal and external validity are important to observe and note (Polit & Beck). If this writer were to carry out this study, it would have to be reflective of how the researcher performed it originality.
5.3 Quality assessment Studies adopting a randomized controlled trial study design will be categorised as the highest level of evidence, followed by cohort studies and case control studies. This ranking was done according to Oxford Centre for Evidence-Based Medicine's levels of evidence and grades of recommendation [14]. It helps to determine level of biasness of the study and similarly allowing a better critical evaluation of it. Other criteria taken into consideration would be the objective, methodology, findings of the study and the support from reference work with respect to the findings obtained [13]. 5.4 Data analysis The data will be
Forty surveys were completed successfully which resulted in very conclusive answers. Before conducting the survey all ethical guidelines were followed: a disclaimer was placed at the start of the survey informing participants that all information will remain confidential; the participants privacy will be respected; there will be no lasting harm and the participants will know this is entirely voluntary as the participant has the freedom to refuse or withdraw at any time without
The study generated both quantitative and qualitative data. The data was then coded to make it possible to group the responses into categories (Roebuck, 2015). Raw data was then transferred from data gathering tools to a tabular form for
There were 523 participants all undergraduates from psyc121 course at Victoria University of Wellington. All participants who gave consent and completed the questionnaire received course credit. This was also approved by the ethics committee and all participation in the study remained anonymous.
This research has numerous restrictions that must be taken into account for including: a short time frame, my level of experience, my skills in research methods, language barrier. I remain optimistic that all the limitations foreseen can be overcome.
Upon entering the study students signed in and were handed an informed consent. Participants were randomly assigned to a condition by picking a slip of paper from alternating cups that contained a number one through eight. Students then took a seat an individual computers and informed consents were reviewed, signed and collected by a research assistant. Participants were provided with headphones by the research assistants if they did not bring their own. Participants then began the survey. They were first asked to report their age in years. If they responded with an age less than 18 years they were thanked for their time and no further questions were asked. Students 18 years and older proceeded with the survey. They were then
As mentioned, the research method used for this study was participant observation. This was further divided into three different segments. Each of these segments featured its own distinct observation site and involved one hour of observation per site.
