Functional Analysis and the Big Four
Functional Analysis
- Functional analysis is a systematic evaluation of a client's behavior in their environment to determine the function(s) of behavior(s).
- It is the final component of the Skill Based Assessment (SBA).
- It includes interviews, indirect assessments, direct observations, and functional analysis.
- Functional analysis is the most precise way to determine the true function of a behavior.
- RBTs will be supervised by a BCBA, specifically someone trained in problem behavior and functional analysis.
- Functional analysis compares target behaviors across different environmental conditions.
- A research design must be used (e.g., multi-element, reversal).
History of Functional Analysis
- Functional analysis dates back to Lovaas in the 1960s.
- Iwata's controlled analysis is the most famous.
- For self-injurious behavior (SIB), escape was not always the function; there was a variety of functions.
Attention Condition
- The therapist imitates the attention the client is used to getting.
- The BCBA decides where in the escalation cycle to reinforce (provide attention).
- Reinforce precursor behaviors if they are reliable and consistent.
- If there are no reliable precursors, reinforce the actual aberrant behavior.
Tangible Condition
- Tests if the function of behavior is to access tangibles or preferred items/activities.
- The clinician deprives access to preferred tangible items.
- Tangible items are only provided contingent on the aberrant behavior.
- Attention is provided non-contingently.
- No demands are placed.
- Consult with the BCBA to determine where in the escalation cycle to reinforce with the tangible item (precursor or aberrant behavior).
Escape Condition
- Tests if the function of behavior is to escape demands.
- Ensure the work is non-preferred.
- Process them through the work to ensure it's not a skill deficit.
- When problem behavior occurs, demands stop.
- There is a short break, but work starts again.
- Decide where in the escalation cycle to reinforce behavior with cessation of demands.
Alone Condition
- Tests if the function of behavior is non-socially mediated (occurs when nobody is present).
- The therapist is sometimes around to keep the child safe, especially with self-injury.
- Intervene if it's a dangerous behavior and determine where in the escalation cycle to intervene.
Iwata Article (1982, 1994)
- Conditions and contingencies tested:
- Social disapproval
- Client plays alone with toys, teacher in the room pretending to work.
- Attention (reprimand) is given when aberrant behavior occurs.
- Academic demand (escape)
- Learning trials presented with a three-prompt procedure.
- Tasks stopped when aberrant behavior occurred.
- Control condition
- Client and teacher in the room with toys available, social praise given.
- Behavior ignored unless too dangerous.
- Alone
- Client alone in the room with no toys or materials.
- No consequences for aberrant behavior.
- Missing from Iwata's article: access to tangible condition.
Interpreting Functional Analysis Graphs
- Data should be graphed with multiple data paths.
- Look for differences in the graph (high vs. low data paths, spikes).
- If no differences are distinguishable, it could indicate automatically maintained behavior.
Graph Examples
- Child 1: Problem behavior spikes during academic tasks, indicating escape function.
- Child 2: Data paths are overlapping and high, indicating automatically maintained behavior.
- Child 3: Problem behavior spikes in the alone condition.
- Child 4: Problem behavior spikes during social disapproval and academic tasks.
Concerns with Traditional Functional Analysis
- Behaviors co-occur together (e.g., escaping a task while also gaining attention).
- Safety concerns if not reinforcing precursor behaviors.
- Analog conditions: experimenters run conditions in a different room; may not be representative of natural environment.
- Evolution in the process of functional analysis
- Components:
- No descriptive assessment (ABC data)
- No closed-ended assessments like FAST or QABF
- Open-ended interview with parents or teachers
- Only two conditions: a synthesis of multiple contingencies, and a control condition
Open-Ended Interview
- Build rapport with parents/teachers.
- Let the person know that they are experts on their child.
- No yes/no questions.
- Ask the "million dollar question": "If I had a million dollars, what could you do to get the problem behavior to start right now, and what could you get it to stop?"
- Ask about the most concerning problem behavior, setting events, and consequences.
Analysis Design
- Based on the interview, design a test condition and a control condition.
- Can be done in less than 30 minutes.
- Leads to effective treatment.
Example: Austin's Partnership Foundation
- Baseline: testing and control condition
- Control condition: no problem behavior
- Testing condition: problem behavior occurs when demands are placed, preferred activities restricted, attention is stopped.
- Treatment: teaching a functional communication response
- Simple FCR: Say "My way" to gain access back to things and stop demands.
- Intermediate FCR: "Excuse me. Can I have my way?"
- Complex FCR: "Excuse me, Julia, can I have my way, please?"
- Ideal FCR: Same vocal response, but in a different location.
- Delay response: "Hey. Can I wrap it up?"
- Functional communication responses increased as problem behavior decreased.
- Tolerating response introduced: "Okay. No problem."
- Emphasis on the importance of both functional analysis and effective treatment.
The Big Four
- Functional Assessment Research Informs Preventative Behavior Analysis
- Conceptualized in the 1980s by Drs. Barbara Etzel and Shala Eli.
- Focus areas:
- Teaching safe, effective, and respectful communication of needs, likes, and dislikes.
- Teaching how to safely, effectively, and pleasantly gain attention and affection.
- Promoting joyful engagement in activities alone and with others.
- Teaching safe, effective, and diplomatic coping with adversity.
Proactive vs. Reactive
- Proactive: teach these functions of behavior to the child prior to problem behavior occurring.
- Reactive: address problem behavior as soon as a child comes into your clinic.
- Conduct in-the-moment assessment to address changing functions.
- Teach all functions at once, as they co-occur.
Role of the Registered Behavior Technician (RBT)
- Assist with ABC data collection.
- Assist with data collection during FA or treatment.
- Implement skill acquisition plans.
- Teach the child to engage in appropriate skills and no longer engage in problem behavior.
