Pilot study | All you need to know

Pilot studies can be instrumental before embarking on a larger research project.

A pilot study, often known as a “feasibility study,” assesses the possibility of a future, full-scale project before doing any large-scale quantitative research. It entails picking a small sample size and running the study on them. By spotting any errors in the techniques the researcher devised, time and, in certain situations, can save.

Also, Did you know that a researcher can identify any ambiguities (i.e., strange items), confusion in the information provided to participants, and issues with the task designed by conducting a pilot study?

Reasons for conducting pilot study

• Process: where the viability of the primary study’s essential steps are for evaluation(e.g., recruitment rate; retention levels, and eligibility criteria)
• Resources: evaluating potential issues with time and resources that may arise during the pilot study (e.g., how long the pilot study will take to complete; whether using specific equipment will be feasible; or whether the form(s) of evaluation chosen for the pilot study are as effective as possible).
• Management: Handling issues include issues with the study team and data management. For example, whether there were problems with collecting all the data needed for future analysis, whether the collected data are highly variable and whether one can evaluate data from different institutions together.

Pilot Study – factors to consider

You want your research to be informative and valuable to your field of study, hence consider the following when conducting a pilot study.

• Selection and sample size Your data must be representative of the study’s intended population. You should estimate the feasibility of your sample size using statistical methods.
• Ascertain the prerequisites for a successful pilot study based on your specific objectives of the study.
• When recruiting subjects or collecting samples, make sure the process is simple and straightforward.
• Always put the measuring instrument through its paces. This could be a questionnaire, or it could be the equipment or methods used. Is it feasible and feasible? What can be done to improve it?
• Entry and analysis of data To determine whether your proposed study is appropriate for your data set, run the trial data through your proposed statistical analysis.
• Make a flow chart of the procedure.

Importance of pilot study

Pilot studies should be part of research approaches on a regular basis because they:

• Help define the research question.
• Put the proposed study design and process to the test. This could alert you to potential problems with your project.
• Educate yourself on various techniques and methods related to your field of study.
• Assess the feasibility of your research to save time, effort and money.
• Focus on providing preliminary data that you can use to increase your funding chances and persuade stakeholders that you have the necessary skills and expertise to successfully complete the research.
• Evaluating the usefulness and viability of the main study and performance of research tools
• Recognizing the need to change procedures that don’t produce valid data
• Gathering initial data and calculating the project’s estimated time and cost
• It is recognizing and resolving any flaws or logistical issues and identifying the resources required for the study.
• Enhancing the study’s trustworthiness and credibility
• Testing out the interview process.
• Allowing researchers to become familiar with the protocol’s guidelines and adopt consistent methods

The drawbacks of pilot studies

• Require additional expenses, resources, and time.
• Don’t promise that the pilot study will be successful.
• Contamination of data
• If the pilot study results are released, funding organizations might be hesitant to support a further study.
• Due to the tiny sample size, the inability to evaluate the treatment’s effects can be a disadvantage.

Key takeaways

• Before conducting a larger study, researchers could indeed conduct a pilot study: a small-scale study that allows them to fine-tune their research topic and study methods.
• Pilot studies can help determine the best research methods, troubleshoot unexpected project issues, and resolve whether a research project is feasible.
• Both quantitative and qualitative social science research can benefit from pilot studies.

FAQS

Q1. What effect does a pilot study have on validity?

Ans. Pilot studies are essential in intervention development because they improve subject recruitment and intervention delivery while allowing investigators to determine sample size requirements more accurately.

Q2. Is it always necessary to conduct pilot studies?

Ans. Pilot studies are recommended for all research. Because scientific research only sometimes goes as planned, you should optimize the process to reduce unforeseen events. 

Q3. Do I need ethical approval for a pilot study?

Ans. If you are collecting data to inform a more extensive pilot study, you must apply for ethics approval.
