Definitions:

ABAB Design

A research design involving four phases: baseline (A), intervention (B), return to baseline (A), and reintroduction of the intervention (B), used to determine the effect of an intervention.

Internal Validity

The extent to which a study can demonstrate a cause-and-effect relationship between variables, without influence from external factors.

External Validity

The degree to which the outcomes of research can be applied to different contexts and populations beyond the experimental environment.

Reversal Design

A single-subject experimental design in which behavior is measured to provide a baseline (A), then again after the treatment has been applied (B), then again after the conditions during baseline have been reintroduced (A), and then once again after the treatment is reintroduced (B). Also known as ABAB design.
