Përmbledhja	A Pilot ABAB design is a small-scale feasibility trial of the ABAB reversal design, conducted with one or a few participants to test whether an intervention produces reliable behavior change under alternating baseline and treatment conditions before committing resources to a larger study. It combines the internal-validity logic of the ABAB reversal with the limited scope and preliminary aims of a pilot investigation.	A pilot randomized controlled trial (pilot RCT) is a small-scale, fully randomized experiment conducted before a definitive RCT to test the feasibility of study procedures, estimate key parameters such as recruitment rates and effect-size variability, and identify practical barriers. It uses the same randomization, intervention, and measurement protocol as the planned full trial but on a fraction of the target sample. The goal is not to confirm efficacy but to refine and justify the main trial design.
