A pilot study is a small-scale preliminary research project conducted to test the feasibility, time, cost, and adverse events involved in a larger study. It helps researchers identify potential issues and refine their methods before committing to a full-scale investigation. This initial phase is crucial for ensuring that the main study is well-designed and effective. Typically, a pilot study involves a limited number of participants and may focus on specific aspects of the research, such as data collection techniques or survey instruments. By analyzing the results, researchers can make necessary adjustments to improve the overall quality and reliability of the main study, ultimately leading to more valid conclusions.
