Which statement correctly differentiates a functional assessment from a functional analysis?

• A. Functional assessment identifies potential functions; functional analysis tests hypotheses by manipulating antecedents and consequences.
• B. Functional assessment identifies behavior frequency; functional analysis manipulates reinforcement.
• C. Functional assessment always uses experimental design; functional analysis uses interviews.
• D. Functional assessment focuses on medical factors; functional analysis focuses on cognitive factors.

Answer: (A)

Understanding the difference between a functional assessment and a functional analysis lies in moving from identifying possible reasons for a behavior to experimentally testing those ideas. A functional assessment gathers information from multiple sources—interviews, direct observations, and ABC data—to generate hypotheses about what might be maintaining the behavior. It provides possible functions rather than a confirmed cause. A functional analysis takes the next step and tests those hypotheses in a controlled way by systematically changing the events that come before the behavior (antecedents) and the events that follow the behavior (consequences). By seeing how the behavior changes under different conditions, we can confirm which function is actually driving it. So, the statement that functional assessment identifies potential functions and functional analysis tests hypotheses by manipulating antecedents and consequences best captures this progression from hypothesis generation to experimental testing. The other options mix up what each process emphasizes—such as focusing only on frequency, or on interviews vs experiments, or on medical/cognitive factors—without describing the core distinction accurately.
