“The Radiologist of PhD dissertation”-Seriously 😂? If you're unfamiliar, a radiologist is responsible for diagnosing specific medical conditions. However, you might be wondering why this is relevant if you're currently reading to address a research problem rather than a health issue 🤔. Don't dismiss it just yet! I aim to shift your perspective by the end of this article and introduce you to the equivalent of a "radiologist" for PhD dissertations. Let's explore further.

In this blog, we will be talking about the “diagnostic research design”. But why is it called the radiologist of PhD dissertation? Let me explain to you with a story.

Earlier in my childhood, whenever I got into a health issue, my mother used to give me some medicines but when the health issue became worse, she used to take me to the doctor. Why didn't she take me to the doctor earlier? Because she knows the tonic to temporarily stop the issue. But the problem is when the health problem became worse, she didn’t have any solutions. But how only the doctors have the solutions? Only because of the knowledge? Nahhh!! There is something else but what is that? Let’s find out.

The doctors, especially the radiologists, know the root cause of the problem and then they solve the problem. That is also what the “diagnostic research design” does. Now, let us know what diagnostic research design is before we dive deep into the topic.

Diagnostic research design is a type of research study that aims to identify the cause of a problem or phenomenon by analyzing and interpreting data. It is used to determine the underlying factors or variables that contribute to a particular situation or condition and to provide information for decision-making and problem-solving. This type of research design is often used in healthcare, psychology, social sciences, and business to diagnose problems and find effective solutions.

Now, we have a little idea about what diagnostic research design is but why should we choose diagnostic design over other research designs? So, let us know about it.

Diagnostic research design can be useful for researchers in several ways:

• Identifying the cause of a problem: By using diagnostic research design, researchers can investigate the underlying factors or variables that contribute to a particular problem or phenomenon. This can help them to identify the cause of the problem and develop effective solutions to address it.

• Providing data for decision-making: Diagnostic research design can provide valuable data that can be used to inform decision-making. For example, it can help organizations to make informed decisions about resource allocation, policy development, and program implementation.

• Improving research methods: By using diagnostic research design, researchers can improve their understanding of the research methods used to investigate a problem. This can help them to refine their research questions, design more effective studies, and analyze data more accurately.

• Contributing to knowledge development: Diagnostic research design can contribute to the development of knowledge in a particular field. By identifying the cause of a problem or phenomenon, researchers can add to the existing knowledge base and contribute to the development of new theories and frameworks.

Now, along with the advantages, the disadvantages come and we need to take care of those in order to fully utilise diagnostic research design. So, what are the disadvantages? It’s simple, what can help you to make a better decision. But I will prove you wrong in this if you think like this. Want to know why? Please keep on reading then.

One disadvantage of diagnostic research design is that it can be time-consuming and expensive. This is because it often involves collecting and analyzing large amounts of data from multiple sources, which can require significant resources and expertise. Additionally, the diagnostic process itself can be complex and may require specialized knowledge and skills, such as statistical analysis, data modelling, or medical expertise.

Another potential disadvantage of diagnostic research design is that it can be limited by the availability and quality of data. In some cases, relevant data may not be available or may be incomplete, which can limit the accuracy and validity of the diagnostic process. Additionally, the quality of the data can also affect the reliability of the findings, and researchers may need to take steps to ensure that the data is accurate and unbiased.

Finally, the results of a diagnostic research design may not be immediately actionable. In some cases, the findings may require further study or analysis before specific actions or interventions can be developed and implemented. This can delay the resolution of a problem or the implementation of an effective solution, and may require additional resources and time.

Now, we have gathered a little idea about the advantages and disadvantages of diagnostic research design. Now, if we are comfortable with handling the disadvantages, then we can know how to use diagnostic tools. If we are not, you can always comment on what topics you want to cover with us in the upcoming blogs and also whether you have enjoyed this blog till this or not.

If you are planning to use a diagnostic research design in your PhD research, the following steps can help guide your process:

• Define the research question: Identify a specific problem or phenomenon that you want to investigate. Your research question should be focused and answerable and should be framed in a way that allows you to investigate underlying causes or contributing factors.

• Select a sample: Determine the sample of participants or cases that you will use to investigate your research question. Your sample should be representative of the population you are interested in studying and should provide sufficient data to allow you to conduct a diagnostic analysis.

• Collect data: Gather data from your sample using appropriate methods. This may include surveys, interviews, observations, or other forms of data collection. You may also need to access secondary data sources, such as medical records or administrative data.

• Analyze the data: Use appropriate statistical or qualitative analysis methods to identify the underlying factors or variables that contribute to the problem or phenomenon you are investigating. This may involve developing a diagnostic model, such as a causal loop diagram, that allows you to identify relationships between variables.

• Draw conclusions and make recommendations: Based on your analysis, draw conclusions about the underlying causes of the problem or phenomenon you are studying. Make recommendations for interventions or solutions that can address the root causes of the problem.

• Communicate your findings: Present your findings in a clear and concise manner, using appropriate visualizations and supporting evidence. Your communication should be targeted to your intended audience, which may include academic peers, policymakers, or other stakeholders.
