B-03: Assisting with Functional Assessment Procedures
This is a particularly important task for RBTs to understand, as identifying the why behind a behavior is critical for developing effective and ethical interventions.
Let’s continue with our established detailed and comprehensive approach.
Clear Explanation: What is a Functional Assessment?
A Functional Assessment, often referred to as a Functional Behavior Assessment (FBA), is a systematic process used by behavior analysts (BCBAs/BCaBAs) to identify the probable function or purpose of a specific behavior, particularly challenging or problem behavior.
The core idea in Applied Behavior Analysis (ABA) is that behavior doesn’t occur in a vacuum; it serves a purpose for the individual. This means it is learned and maintained by the consequences it produces in the environment.
By understanding why a behavior is happening, interventions can be designed that are:
- More effective in the long run.
- More ethically sound.
- Focused on teaching appropriate replacement behaviors that serve the same function, or on altering antecedents (what happens before) and consequences (what happens after) to make the problem behavior irrelevant, inefficient, or ineffective.
The four common functions of behavior that FBAs aim to identify are:
- Attention: To gain social attention from others (e.g., peers, adults, caregivers).
- Escape/Avoidance: To get out of, delay, or avoid an unpreferred task, situation, demand, or even social interaction.
- Access to Tangibles: To get a preferred item (like a toy or food) or access to a preferred activity.
- Automatic Reinforcement (often called Sensory Stimulation): To produce an internal state or sensation that is reinforcing in and of itself, independent of external social consequences.
This can mean the behavior produces pleasure or alleviates an unpleasant internal state (like pain or boredom).
It’s crucial to understand that Registered Behavior Technicians (RBTs) do NOT conduct FBAs independently, nor do they determine the function of behavior or design interventions based on FBA results. That responsibility lies solely with the supervising BCBA or BCaBA.
However, RBTs play an indispensable assisting role in the FBA process. This primarily involves gathering critical data through various methods, as directed by their supervisor.
This assistance mainly involves collecting information through indirect and direct descriptive methods, and sometimes, under very close and direct supervision, assisting during experimental functional analyses.
Detailed Breakdown of RBT Assistance in Different FBA Components
Let’s explore the different ways RBTs contribute to the FBA process:
Assisting with Indirect Functional Assessments
- What they are: Indirect assessments involve gathering information about the behavior without directly observing it as it occurs.
These methods rely on the recollections and perceptions of individuals who know the client well. Common methods include:- Structured Interviews: The BCBA will conduct interviews with the client (if appropriate, depending on their age and communication skills), parents, teachers, caregivers, and other relevant individuals.
- Checklists and Rating Scales: Standardized forms (e.g., Motivation Assessment Scale (MAS), Questions About Behavioral Function (QABF), Functional Analysis Screening Tool (FAST)) are completed by individuals familiar with the client.
These tools gather information about perceived antecedents, consequences, and potential functions of the problem behavior.
- RBT’s Role in Assisting with Indirect Assessments:
- Providing Information as an Informant: As someone who works directly and frequently with the client, the RBT may be asked by the supervisor to complete a behavioral checklist or answer specific interview questions based on their firsthand observations and experiences with the client.
In this role, the RBT provides factual, objective information as accurately as possible. - Assisting Others in Completing Forms (Logistical Support): In some cases, an RBT might be asked by the supervisor to help a caregiver (e.g., a parent with literacy challenges or who is unfamiliar with behavioral terminology) understand the questions on a checklist and accurately record their responses.
This is done without interpreting the questions or leading the caregiver’s answers the RBT acts as a scribe or clarifier of the questions themselves. - Gathering Relevant Records: Under the direction of the supervisor, the RBT might be asked to help gather relevant documents such as previous behavioral reports, school Individualized Education Program (IEP) documents, or medical records, if authorized.
- Providing Information as an Informant: As someone who works directly and frequently with the client, the RBT may be asked by the supervisor to complete a behavioral checklist or answer specific interview questions based on their firsthand observations and experiences with the client.
- Key for RBTs: Your input as an informant is valuable because of your direct contact with the client. However, it’s just one piece of the FBA puzzle.
Your role is to provide data and observations, not to interpret the information or draw conclusions about function.
Assisting with Direct Descriptive Functional Assessments (Observational Methods)
This is where RBTs often have the most significant and frequent involvement in FBA data collection.
Direct descriptive assessments involve observing the target behavior in the natural environment where it typically occurs and meticulously recording relevant surrounding environmental events.
- (a) ABC Data Collection:
- What it is: This is the cornerstone of descriptive assessment. ABC data involves recording the sequence of events surrounding the behavior:
- A – Antecedent: What happened in the environment immediately before the target behavior occurred? (e.g., a demand was placed, attention was withdrawn, a preferred item was denied, the client was alone in the room, a loud noise occurred).
- B – Behavior: An objective, observable, and measurable description of the target problem behavior itself (using the precise operational definition provided by the supervisor refer back to Task A-01 for more on operational definitions).
- C – Consequence: What happened in the environment immediately after the behavior occurred? (e.g., attention was provided, the demand was removed, the item was given, the behavior was ignored by others, the client engaged in self-soothing).
- RBT’s Role in ABC Data Collection:
- Understand the Operational Definition: Before collecting any ABC data, the RBT must be crystal clear on the exact operational definition of the target behavior(s) being assessed.
This definition will be provided by the supervisor. - Observe and Record: When the target behavior occurs, the RBT records the Antecedent (A), the Behavior (B), and the Consequence (C) as objectively and descriptively as possible on an ABC data sheet (which can be a paper form or a digital app).
- Timeliness: Data should be recorded as soon as possible after the A-B-C sequence occurs to ensure accuracy and recall of important details.
Waiting too long can lead to forgetting crucial information. - Objectivity is Key: Describe only what you see and hear. Avoid inferring internal states, emotions, or intentions (e.g., write “client dropped to the floor and cried” NOT “client was angry and threw a temper tantrum”).
Crucially, avoid guessing the function in your recording (e.g., write “Teacher said ‘Time for math’ (A), Client screamed (B), Teacher removed the math worksheet (C)” NOT “Client screamed to get out of doing math”).
- Understand the Operational Definition: Before collecting any ABC data, the RBT must be crystal clear on the exact operational definition of the target behavior(s) being assessed.
- Detailed Examples of ABC Data for Different Potential Functions:
- Possible Attention Function:
- A: Mom is on the phone, not looking at child.
- B: Child loudly bangs a toy on the table and whines.
- C: Mom hangs up the phone, looks at child, and says, “What do you need, sweetie?”
- Possible Escape Function:
- A: RBT presents a math worksheet and says, “Time to do the first 3 problems.”
- B: Client slides out of their chair and goes under the table.
- C: RBT removes the worksheet and says, “Okay, let’s take a break from math for now.”
- Possible Tangible Function:
- A: Client sees a peer playing with a preferred toy train.
- B: Client grabs the train from the peer’s hand.
- C: Client now has the train and begins playing with it.
- Possible Automatic Reinforcement:
- A: Client is sitting alone in their room during quiet time, with no specific demands or social interactions occurring.
- B: Client begins to rock their body back and forth rapidly and hums a repetitive tune loudly.
- C: No apparent external social consequence occurs; the client continues rocking and humming. (Note: For automatic reinforcement, the “consequence” is the sensory stimulation produced directly by the behavior itself.
This may not be directly observable to the RBT, but the lack of an obvious social consequence is an important piece of information to note).
- Possible Attention Function:
- RBTs must understand that they will likely need to record many instances of ABC data for the BCBA to analyze and identify potential patterns that suggest a function.
- What it is: This is the cornerstone of descriptive assessment. ABC data involves recording the sequence of events surrounding the behavior:
- (b) Scatterplot Data Collection:
- What it is: A scatterplot is a grid-like data collection tool used to record when and where a target behavior occurs across different times of day, activities, settings, or even with different people.
- It helps the BCBA identify temporal or contextual patterns, such as whether the behavior is more likely to occur during math class, just before lunchtime, when a specific caregiver is present, or only on certain days of the week.
- RBT’s Role in Scatterplot Data Collection: The supervisor will provide a scatterplot data sheet. The RBT’s task is to accurately mark on the grid whether the target behavior occurred (or occurred at a high/low rate, depending on how the scatterplot is set up) during specified time intervals or activities throughout the day(s) of observation.
- Example: A scatterplot might have “Time of Day” in 30-minute intervals (e.g., 9:00-9:30 AM, 9:30-10:00 AM) along one axis and “Days of the Week” (Monday-Friday) along the other axis.
The RBT would place a mark (or a symbol indicating frequency/intensity) in the corresponding box if the target behavior (e.g., screaming) occurred within each time block.
After several days of data collection, patterns might emerge (e.g., data might show that screaming most often occurs between 10:00-10:30 AM, which the BCBA might then correlate with a transition to a less preferred activity).
- What it is: A scatterplot is a grid-like data collection tool used to record when and where a target behavior occurs across different times of day, activities, settings, or even with different people.
Assisting with Functional Analysis (FA) / Experimental Analysis (Under Close, Direct Supervision Only)
- What it is: A Functional Analysis (FA) is the most rigorous and precise type of FBA. It involves systematically manipulating antecedents and consequences in a controlled (often analog or simulated) setting to directly test hypotheses about the function(s) of a behavior.
Different conditions are rapidly alternated (e.g., an attention condition, an escape/demand condition, a tangible condition, an alone/ignore condition, and often a play/control condition), and the target behavior is measured in each condition.
By comparing the rates of behavior across these conditions, the BCBA can more definitively identify the function. - RBTs DO NOT DESIGN, CONDUCT, OR INTERPRET FAs INDEPENDENTLY. This is a complex and potentially risky procedure that requires specialized training and is solely the responsibility of a qualified BCBA. FAs can sometimes temporarily increase the problem behavior during certain conditions.
- RBT’s Role (Assisting Under Direct and Immediate Supervision of the BCBA):
- Material Management: Preparing and organizing specific materials needed for each condition (e.g., having preferred toys readily available for a tangible condition, or specific work tasks for a demand condition).
- Implementing Conditions as Trained and Directed: The BCBA will provide very specific training and instructions on how the RBT should behave and respond during each condition of the FA. For example:
- In an “attention condition,” the RBT might be instructed to engage with the client (e.g., provide brief verbal attention or a light touch) only when the target problem behavior occurs.
- In a “demand condition” (testing for escape function), the RBT might be instructed to continuously present specific tasks or instructions, and then to briefly remove the demand (e.g., for 30 seconds) only when the target problem behavior occurs.
- Accurate Data Collection: Taking precise frequency or duration data on the target problem behavior during these short, controlled sessions.
This data is critical for the BCBA to compare rates of behavior across the different FA conditions. - Strict Adherence to Safety Protocols: Because FAs can sometimes temporarily increase problem behavior, the RBT must be acutely aware of and strictly adhere to all safety procedures and protocols established by the BCBA.
- Following the BCBA’s Lead: The BCBA will be present, directly observing, guiding the session, and making real-time decisions.
The RBT’s role is to follow these directions precisely and immediately.
- Emphasis: The RBT’s role in an FA is highly structured, directly supervised, and involves implementing specific procedures exactly as taught by the BCBA, not making independent clinical judgments.
General Principles for RBT Assistance in Functional Assessment
- Objectivity: Always describe what you observe (see and hear), not your opinions, feelings, or interpretations.
- Operational Definitions: Always use the supervisor-provided operational definition of the target behavior consistently.
- Confidentiality: All information gathered about a client’s behavior and during assessments is highly confidential and must be protected.
- Clear Communication: Report any unusual circumstances, difficulties encountered during data collection, or any safety concerns to your supervisor immediately.
- Knowing the Four Functions (Conceptually): While RBTs do not determine the function of behavior, having a basic conceptual understanding of the four common functions helps in recognizing potentially relevant antecedents and consequences to record during ABC data collection, making the data more useful for the BCBA.
Real-World Examples (Illustrating the RBT’s “Assisting” Role)
- ABC Data Collection for Aggression:
- Supervisor’s Instruction: “Please collect ABC data on any instance of ‘hitting’ (defined for you as ‘forceful contact of the client’s open hand or fist with another person’s body’) for Leo today during your session.”
- RBT’s Action: Throughout the session, whenever Leo hits, the RBT meticulously records on their ABC data sheet:
- A (Antecedent): (e.g., “Peer took a toy from Leo,” or “RBT told Leo ‘Time for work now'”)
- B (Behavior): (e.g., “Leo hit the peer on their arm with an open hand,” or “Leo hit RBT on their leg with a closed fist”)
- C (Consequence): (e.g., “Peer cried and dropped the toy, Leo picked it up,” or “RBT said ‘No hitting’ in a firm voice and briefly paused the work demand”)
- At the end of the session, the RBT submits the completed ABC data sheet to the BCBA for review and analysis.
- Assisting in a Functional Analysis (Demand Condition – BCBA Present and Leading):
- Supervisor’s Plan & Instruction (BCBA is present and leading the session): “Okay, during this next 5-minute demand condition, I want you to continuously present these puzzle tasks to Sara.
If Sara screams (as per her operational definition), I want you to immediately remove the puzzle from her view for 30 seconds, then re-present it. I will be right here tracking the frequency of screaming.” - RBT’s Action: The RBT follows the BCBA’s instructions precisely, presenting the puzzles, removing them contingently if screams occur (and only if they occur), and then re-presenting them.
The BCBA is actively observing, collecting primary data, and ensuring the RBT implements the condition correctly and safely.
- Supervisor’s Plan & Instruction (BCBA is present and leading the session): “Okay, during this next 5-minute demand condition, I want you to continuously present these puzzle tasks to Sara.
Key Terms/Vocabulary (Specific to Assisting with Functional Assessment)
- Functional Behavior Assessment (FBA): A systematic process used to identify the purpose or function of a behavior.
- Function of Behavior: The reason a behavior occurs, typically categorized as Attention, Escape/Avoidance, Access to Tangibles, or Automatic Reinforcement.
- Antecedent (A): Environmental events or conditions occurring immediately before the behavior of interest.
- Behavior (B): The target behavior, which must be operationally defined in observable and measurable terms.
- Consequence (C): Environmental events or conditions occurring immediately after the behavior of interest.
- Indirect Assessment: Methods of gathering information about behavior without directly observing it (e.g., interviews, checklists, rating scales).
- Direct Descriptive Assessment: Methods that involve observing and recording behavior and its surrounding environmental events in the natural setting (e.g., ABC data collection, scatterplots).
- Functional Analysis (FA) / Experimental Analysis: A procedure that involves systematically manipulating antecedents and consequences in a controlled setting to directly test hypotheses about the function of behavior (always led and supervised by a BCBA).
- Hypothesis (about function): An educated guess or proposed explanation about the function of a behavior, formulated by the BCBA based on the FBA data.
- Operational Definition: A clear, concise, objective definition of a behavior, specifying exactly what to measure.
- Problem Behavior/Challenging Behavior: Behavior targeted for reduction because it interferes with learning, poses a safety risk, or limits social inclusion.
- Replacement Behavior: An appropriate behavior that is taught to serve the same function as a problem behavior, making the problem behavior less necessary.
Ethical Considerations for RBTs Assisting with FBAs
- Client Safety: This is always paramount, especially if assisting with FA conditions where problem behavior might temporarily increase. RBTs must be vigilant and follow all safety protocols.
- Objectivity and Accuracy in Data Collection: The data RBTs collect forms the basis for important clinical decisions. It must be unbiased, factual, and accurately reflect observed events.
- Confidentiality: All information gathered about a client, their behavior, and the assessment process is confidential and must be protected according to HIPAA and agency policies.
- Scope of Competence: RBTs must remember they only assist as trained and directed by their supervisor. They do not conduct FBAs independently or interpret FBA data.
They should not accept tasks related to FBA for which they haven’t received adequate training and ongoing supervision. - Reporting: Any concerns about the procedures being used, client safety, or difficulties in data collection must be reported to the supervisor immediately.
Common Mistakes/Misunderstandings (Specific to RBTs Assisting with Functional Assessment)
- Stating the Perceived Function on Data Sheets: A common error is for RBTs to write their opinion about the function on the ABC data sheet (e.g., “He hit me to get my attention”) instead of objectively recording only the A, B, and C as observed.
- Using Subjective or Vague Descriptions: Using terms like “upset,” “angry,” “frustrated,” or “manipulative” instead of describing observable behaviors (e.g., “cried for 2 minutes,” “threw the item on the floor,” “stomped feet,” “said ‘I hate this'”).
- Missing Components in ABC Data: Forgetting to record the antecedent, or only recording the behavior and the consequence, or vice-versa. All three components are vital.
- Recording Non-Immediate Antecedents or Consequences: Focusing on events that happened long before or long after the behavior, rather than the immediate surrounding environmental events.
- Inconsistent Use of Operational Definitions: If the operational definition of the target behavior isn’t consistently applied, the data will be unreliable.
- Providing More Assistance or Deviating from Instructions During FA Conditions: During the highly controlled conditions of an FA, RBTs must strictly adhere to the specific instructions for how to interact and respond.
- Assuming All Problem Behavior is “Bad” or “Manipulative” or Done “On Purpose”: It’s essential to adopt a behavior-analytic perspective, understanding that all behavior, including problem behavior, serves a function for the individual based on their learning history and current environmental contingencies.
Assisting with functional assessment procedures is a responsibility that requires meticulous attention to detail, unwavering objectivity, and a strong adherence to the supervisor’s guidance.
The information RBTs gather is foundational to the BCBA’s ability to create effective and ethical behavior change plans..
