Why is pilot testing especially important in nursing intervention research? (Select all that apply.)
a. It represents the first trial of the intervention and might enable direct application without further testing.
b. It is an opportunity to discover whether the intervention works as expected to work in a real-life scenario.
c. It poses risk to fewer individuals, so it decreases the number of actual lawsuits that will result if harm ensues.
d. It provides a good estimate of the number of subjects the actual project will require in order to demonstrate statistical significance.
e. It gives the team a chance to refine instructions and details of intervention application and to examine its methods of data collection.
ANS: B, D, E
For multiple reasons, pilot or field testing of an intervention is recommended. Pilot testing is helpful for the following reasons: (1) to assess the feasibility and acceptability of the intervention, (2) to determine the feasibility and acceptability of the design and procedures, and (3) to facilitate the determination of treatment ES to use in power analysis calculations of sample size. In general, pilot studies are very useful for determining whether the intervention as a prototype will work and if it is feasible. It also is an opportunity to test and refine instructions, manuals, or training programs to ensure that study procedures are understandable and the preparation of study staff is adequate.
