What is a key characteristic of Multiple Baseline Design?

A key characteristic of Multiple Baseline Design is that treatment is introduced to different participants or conditions successively over time. This allows for the examination of the effects of an intervention while controlling for potential confounding variables. By staggering the introduction of treatment across various subjects or settings, it becomes clearer whether observed changes in behavior are attributable to the intervention itself rather than other external factors or natural fluctuations in the behavior being studied.

This design is particularly useful in situations where a withdrawal of treatment is not ethical or feasible. By collecting baseline data for each participant before introducing the treatment, therapists can compare changes in behavior across different units or individuals, ultimately contributing to a stronger evidence base for the effectiveness of the intervention.
