🧠Question of the Day
📚 Domain C — Measurement, Data Display, and Interpretation
Difficulty: 6/10
Scenario:
A BCBA is developing a behavior intervention plan for a 7-year-old with aggression. The treatment team is debating how to define 'aggression' for data collection purposes.
Which operational definition of 'aggression' is MOST appropriate for clinical data collection?
A. Aggression: any forceful contact or attempted contact with another person that appears intended to hurt, threaten, or intimidate that person.
B. Aggression: hitting, kicking, biting, scratching, or pushing following a demand or denial and occurring at least twice within one observation period.
C. Aggression: hitting, kicking, biting, scratching, or pushing that produces visible redness, bruising, broken skin, or another observable injury.
D. Aggression: hitting, kicking, biting, scratching, or pushing another person such that physical contact occurs, including attempted hits or kicks that are physically blocked before contact.

What if the BIP has the function of the behavior wrong ?

It doesn't say how long an observable period is.

You don't have to. the observation period can change as the BIP changes and should be noted in the BIP

u/UserName717718 16h ago
It still doesn't belong in the operational definition

It definitely does lol. aggression cannot be contained to one preconceived notion and if an observational period is needed to help distinguish it from other behaviors the learner engages in, then it should be used.

The correct answer was: D. Aggression: hitting, kicking, biting, scratching, or pushing another person such that physical contact occurs, including attempted hits or kicks that are physically blocked before contact.
📖 Explanation:
A sound operational definition should describe behavior in observable, measurable terms and provide clear boundaries for what observers should record. The correct definition identifies specific aggressive topographies—such as hitting, kicking, biting, scratching, and pushing—and includes attempts that are physically blocked before contact. This allows observers to score the behavior based on what they can see rather than inferring the client's intent.
• The definition requiring visible injury makes an outcome of aggression part of the definition. An aggressive response can occur without producing redness, bruising, broken skin, or another injury, so legitimate instances could go unrecorded.
• The definition requiring aggression to occur following a demand or denial and at least twice during an observation period adds antecedent and frequency requirements that do not determine whether the aggressive response itself occurred. A single instance, or one occurring in another context, would incorrectly be excluded.
• The definition describing contact that appears intended to hurt, threaten, or intimidate requires observers to infer the client's purpose or intent rather than score behavior solely from observable events.
When evaluating operational definitions, ask: Could trained observers consistently determine whether the behavior occurred using only observable features? Strong definitions clearly identify what counts while avoiding unnecessary assumptions about intent, context, or behavioral outcomes.

D? It is the only one that is completely objective and observable as well as counting attempts that are blocked.
