Board Certified Behavior Analyst (BCBA) Practice Test

The main purpose of conducting a functional assessment in behavior analysis is to obtain information that leads to a clear and testable hypothesis regarding the function of a behavior. This involves systematically gathering data about the circumstances under which the behavior occurs, including antecedents (triggers) and consequences (results). By understanding the context and conditions surrounding the behavior, practitioners can form a hypothesis about its purpose, which can inform effective intervention strategies. Through this assessment, behavior analysts can determine whether behaviors are maintained by reinforcement, avoidance, or other factors. This understanding is critical for developing targeted interventions that address the function of the behavior, rather than just the behavior itself. Ultimately, forming a solid hypothesis based on functional assessment data leads to more informed decision-making in treatment planning and implementation.
