Board Certified Behavior Analyst (BCBA) Practice Test

If data from a functional analysis do not support the original hypothesis, what should be the next step in the assessment process?

1. Conclude the assessment

2. Alter the hypothesis regarding the maintaining variable of the behavior based on the results of the functional assessment

3. Conduct a new assessment

4. Continue with the current hypothesis

The correct answer is: Alter the hypothesis regarding the maintaining variable of the behavior based on the results of the functional assessment

When data from a functional analysis do not support the original hypothesis, the most appropriate step to take is to alter the hypothesis regarding the maintaining variable of the behavior based on the results of the functional assessment. This approach is vital because it reflects the nature of behavior analysis, which is grounded in empirical evidence and relies on adjusting beliefs in response to data. Changing the hypothesis allows clinicians to develop a more accurate understanding of the factors that may be influencing the behavior. It also sets the stage for designing interventions that are tailored to the identified maintaining variables, leading to more effective behavior modification strategies. This response is a fundamental principle of scientific inquiry, relying on observations to guide theoretical constructs and practical applications. Moving in this direction remains consistent with the iterative process of assessment in behavior analysis, where ongoing data collection informs and improves the understanding and treatment of challenging behaviors. It underscores the importance of flexibility and responsive changes in hypotheses to align with observed outcomes rather than sticking rigidly to initial assumptions.
