What is the significance of establishing a baseline in therapy?

Establishing a baseline in therapy is significant because it allows for the identification of trends and behaviors without the influence of intervention. A baseline serves as a starting point that reflects the client's condition, behaviors, or responses before any therapeutic techniques are introduced. This is crucial for accurately assessing the impact of the therapy, as it provides a frame of reference to compare any changes observed during the intervention phase.

When a baseline is established, practitioners can track developments over time and analyze how the therapy influences the client. Without this baseline, it would be difficult to discern whether observed changes are a result of therapy or other external factors. Thus, the primary purpose of a baseline is to eliminate the confounding effects of intervention and focus on the natural progression of behaviors or symptoms, supporting informed and evidence-based treatment planning.
