Baseline & Intervention

Baseline data collection is a great start to documenting our understanding of whether or not an effort of behavior change is even needed. Continued data collection on baseline targets provides information on whether behavior change is actually occurring. Together, these are the powerhouse of ABA goal setting and progress monitoring. Walk along with me in this dual month Behavior Bits video below to see an example of baseline data collection, function based interventions decision making, and the data collection to track it. After all, If you document it, then there is solid proof that it happened.

Want to learn more about formal intervention planning? I've got a training coming up for BIP writing in Butte schools. The information is on the picture below and the link to join the zoom meeting is below the picture. Hope to see you there!

Geek Speak

In the field of ABA, research tends to be conducted comparing a single subject to itself rather than comparing groups to one another as randomized control research designs often do. Single Subject Research Design, as noted by CREd Library here, "is also referred to as within-subject or single case experimental designs. These designs provide a framework for a quantitative, scientifically rigorous approach where each participant provides [their] own experimental control."

CREd Library cites McReynolds and Thompson (1986) when describing the phases of this research design: "The conditions in a single-subject experimental study are often assigned letters such as the A phase and the B phase, with A being the baseline, or no-treatment phase, and B the experimental, or treatment phase. (Other letters are sometimes used to designate other experimental phases.) Generally, the A phase serves as a time period in which the behavior or behaviors of interest are counted or scored prior to introducing treatment. In the B phase, the same behavior of the individual is counted over time under experimental conditions while treatment is administered. Decisions regarding the effect of treatment are then made by comparing an individual’s performance during the treatment, B phase, and the no-treatment."

Data collected before any intervention is put into place Baseline data allows us to observe changes that occur when the intervention is put into place and helps us compare behavior under its naturally occurring conditions versus our contrived intervention conditions.


The treatment you implement to increase or decrease the target behavior. Also known as the Independent Variable.
