خلاصه	The Pilot ABA Design is a small-scale single-subject experiment that applies the ABA reversal structure — baseline, intervention, withdrawal — to test the feasibility, acceptability, and preliminary effect of an intervention before committing to a full-scale study. It provides early evidence of whether the treatment produces a detectable change and whether the reversal is ethically and practically achievable.	A pilot AB design applies the two-phase baseline-then-intervention structure of the AB single-subject design in an explicitly exploratory or feasibility mode — before committing to a more rigorous reversal or multiple-baseline study. The researcher collects repeated baseline (A) and intervention (B) data from one or a few individuals primarily to test measurement procedures, estimate effect size, verify data stability, and determine whether a stronger single-case design is warranted and feasible.
