Validity & Triangulation

According to Shadish, Cook and Campbell (2002), there are four primary types of validity that researchers should address to ensure validity is met. The first form is constructed validity. This refers to the degree in which inferences that are made about the nature and displays of theoretical factors. The second form is statistical conclusion validity. This is the use of appropriate and used statistics to determine what the research is perceiving. Internal validity is the third form of validity. This is the validity of inferred and found information about the relationships between the elements of the chosen research design and outcomes. The final form of validity is external validity, this form of validity is used to …show more content…

The reason why is that the research will be employing a qualitative data paradigm. This means that the latter definition suits the research better. However, to make sure that the data collected is valid throughout the entire research the four primary types of validity will be considered. Another way in which the data gathered will stay valid is by using triangulation on the responses to the questions asked.

Denzin (1978) cited in McMurray, Scott and Pace (2008) suggested that there are four types of triangulation. The first type is source triangulation, this is when there are a variety of data sources that are used. The second form is investigator triangulation, this is where more than one researcher are used. Theory triangulation is the third form, and this is when more than one perspective would be used to interpret the data. The final form is methodology triangulation, this is when several different data gathering techniques will be

    The sampling procedures that can be utilized in evaluation research is vast. The selected sampling procedure is important in the consideration of external validity. External validity generalizes the findings to individuals in the study sample with characteristics that are alike (DiClemente et al., 2013). Although, not all research studies will require a sampling procedure that would deliver an external validity.

  • Construct, Internal, and External Validity

    Internal validity, unlike external and construct validity, deals with causal relationships. In other words, the question is whether any additional research that is found is actually associated with the study that is being conducted. The question, again, is whether we can be confident that the outcome of the study is a result of the experiment itself. What this means is that internal validity is the extent to which a change in a given variable is caused by the change in another variable.

  • Qualitative vs Quantitative Research

    The father of quantitative analysis, Rene Descartes, thought that in order to know and understand something, you have to measure it (Kover, 2008). Quantitative research has two main types of sampling used, probabilistic and purposive. Probabilistic sampling is when there is equal chance of anyone within the studied population to be included. Purposive sampling is used when some benchmarks are used to replace the discrepancy among errors. The primary collection of data is from tests or standardized questionnaires, structured interviews, and closed-ended observational protocols. The secondary means for data collection includes official documents. In this study, the data is analyzed to test one or more expressed hypotheses. Descriptive and inferential analyses are the two types of data analysis used and advance from descriptive to inferential. The next step in the process is data interpretation, and the goal is to give meaning to the results in regards to the hypothesis the theory was derived from. Data interpretation techniques used are generalization, theory-driven, and interpretation of theory (Gelo, Braakmann, Benetka, 2008). The discussion should bring together findings and put them into context of the framework, guiding the study (Black, Gray, Airasain, Hector, Hopkins, Nenty, Ouyang, n.d.). The discussion should include an interpretation of the results; descriptions of themes, trends, and relationships; meanings of the results, and the limitations of the study. In the conclusion, one wants to end the study by providing a synopsis and final comments. It should include a summary of findings, recommendations, and future research (Black, Gray, Airasain, Hector, Hopkins, Nenty, Ouyang, n.d.). Deductive reasoning is used in studies...

  • External Validity

    Internal validity should eliminate the possibility of bias both the research design and methodology. However, the most common issues hounding clinicians involve serious shortcomings in external validity (Rothwell, 2006). Thus, the discussion of approaches to strengthen validity shall focus on external validity. Sufficient contextual disclosure: Since qualitative studies often do not believe in the rationalist concept of generalizability, the issue on external validity can be dealt with through adequate, if not full, description of all relevant contextual factors in the study. This disclosure allows the readers to judge on the generalizability of results into their contexts (Rothwell, 2006).

  • Exploring the Four Major Research Philosophies

    800 Words  | 2 Pages

    Research philosophies is a framework by which the research problem should be fundamentally approached, there are four major research philosophies positivism, interpretivism/constructivism, realism and pragmatism (Davies, 2007). Positivism is a philosophical trend in the methodology of science, defining the only source of true, actual knowledge of empirical research and denies cognitive value of philosophical inquiry. According to the positivist philosophy, methodology is not related to the essence of knowledge about the real world, but rather has to do with the operations by which knowledge is constructed. The essential reasoning behind positivism is that, all truthful learning depends on the positive data assembled from noticeable experience, and that any thought past this domain of self evident actuality is powerful. Just explanatory proclamations are permitted to be known as valid, through reason alone (Davies 2007).

    Research is a big component of a well written and credible paper. In order for your research paper to be a reliable source of information it needs to be based off of scholarly articles and books in order to insure that the information you are writing about is correct. With the help of the 21st century technology it is now comparatively easy to do research since most sources are electronic and you can search through them using key words and phrases. Advanced searches can help you narrow down the information even further and help you get the information you need in a fraction of time. Technology is a blessing and a curse in many ways.

    The quality of inferences made on a research study is called validity. The four types of validity that can affect the rigor of a quantitative study are statistical conclusion, internal, construct and external validity. According to Polit & Beck, (2017, p. 234), statistical conclusion validity relates to the empirical relationship between the cause and the effect whereas construct validity covers population, settings, outcomes and treatment. Internal validity refers that outcomes were caused by the independent variables rather than confounding factors and external validity is about the scope of generalization of the study (Polit & Beck,

    What is the purpose of a nursing research study if you do not have validity and reliability? In this article, Identifying a Relationship Between Physical Frailty and Heart Failure Symptoms, a cross section study is done to correlate the relationship between HF symptoms (sleep disturbances, pain, anxiety, dyspnea, depression) and physical frailty.(Denfeld, Winters-Stone, Mudd, Hiatt, & Lee, 2017). Patients with HF were asked a range of questions and given subjective scales where they self reported the previously mentioned symptoms. The ultimate benefit of correlating this would be to prevent frailty therefore reducing the severity of these symptoms.

    Creswell (2009), states that there are three types of designs, qualitative, quantitative and mixed methods. Smith and Davis (2010) states that qualitative research is a field of enquiry that is conducted in a natural setting by a researcher, who may be involved in, or may be part of the data collection process; as it utilizes the views of informants as the basis for the report. Qualitative research attempts to gain and in-depth, holistic picture of the phenomenon one wishes to study by interacting closely with the people being studied; the data collected are usually in the form of words or pictures.
