8.2 Functional behavior assessment

Functional behavior assessment (FBA) is a critical tool in special education. It helps educators understand why students exhibit challenging behaviors and develop targeted interventions. By systematically analyzing triggers and consequences, FBAs guide the creation of effective behavior support plans.

FBAs involve multiple steps, including identifying target behaviors, gathering data through observations and interviews, and forming hypotheses about behavior function. This process enables educators to design interventions that address the root causes of problematic behaviors, promoting positive outcomes for students with special needs.

Definition and purpose

• Functional Behavior Assessment (FBA) systematically identifies the function of challenging behaviors in students with special needs
• FBA forms the foundation for developing effective behavior intervention plans in special education settings
• Understanding the purpose of behaviors helps educators create targeted strategies to support students' social and academic success

1 of 3

• Identify specific target behaviors that interfere with learning or social interactions
• Determine environmental factors triggering or maintaining problematic behaviors
• Develop hypotheses about the function or purpose the behavior serves for the student
• Gather data to inform effective, individualized behavior intervention strategies

Legal requirements for FBA

• Mandated by Individuals with Disabilities Education Act (IDEA) for certain disciplinary actions
• Required before implementing significant changes in a student's educational placement
• Must be conducted by a team of qualified professionals, including those knowledgeable about the student
• Necessitates parental consent and involvement throughout the FBA process

Components of FBA

• FBA consists of multiple assessment methods to gather comprehensive data on student behavior
• Combines indirect and direct assessment techniques to create a holistic understanding of behavior
• Emphasizes the importance of triangulating data from various sources for accurate analysis

Indirect assessment methods

• Review of student records and previous interventions
• Behavior rating scales completed by teachers, parents, and sometimes students
• Structured interviews with individuals familiar with the student's behavior patterns
• Questionnaires designed to gather information about behavior antecedents and consequences

Direct observation techniques

• Naturalistic observation in the student's typical environments (classroom, playground)
• Structured observation using predetermined criteria or checklists
• Video recording for detailed analysis of behavior occurrences and contextual factors
• Scatter plot assessments to identify patterns in behavior across time and settings

Data collection strategies

• Continuous recording captures every instance of the target behavior
• Time sampling techniques record behavior occurrence at specific intervals
• Event recording tallies the frequency of behavior within a set time frame
• Duration recording measures how long a behavior lasts when it occurs

Identifying target behaviors

• Selecting specific behaviors for assessment critical for effective FBA process
• Focuses intervention efforts on behaviors most impacting student's education and social interactions
• Requires collaboration between educators, parents, and sometimes the student to prioritize concerns

Operational definitions

• Clear, observable, and measurable descriptions of target behaviors
• Includes specific actions or vocalizations that constitute the behavior
• Excludes subjective interpretations or vague terms (acting out, being disruptive)
• Enables consistent identification and recording of behavior across observers and settings

Prioritizing behaviors

• Consider frequency, intensity, and duration of behaviors
• Assess impact on student's learning and social relationships
• Evaluate safety concerns for the student and others
• Determine which behaviors, if changed, would have the most significant positive impact

Antecedent analysis

• Examines events and conditions occurring before the target behavior
• Crucial for identifying triggers and developing preventive strategies
• Helps in modifying the environment to reduce the likelihood of problem behaviors

Environmental factors

• Physical setting characteristics (noise level, lighting, seating arrangements)
• Temporal factors (time of day, day of week, seasonal patterns)
• Social context (presence of specific individuals, group dynamics)
• Academic demands (difficulty level, type of task, instructional methods)

Triggering events

• Specific instructions or requests from teachers or peers
• Transitions between activities or settings
• Changes in routine or unexpected events
• Sensory stimuli (sounds, textures, visual inputs)

Consequence analysis

• Investigates what happens immediately after the target behavior occurs
• Identifies factors maintaining or reinforcing the problematic behavior
• Crucial for understanding why behaviors persist and how to modify outcomes

Reinforcement vs punishment

• Positive reinforcement adds a desirable stimulus following behavior
• Negative reinforcement removes an aversive stimulus following behavior
• Positive punishment adds an aversive stimulus following behavior
• Negative punishment removes a desirable stimulus following behavior

Maintaining consequences

• Attention from peers or adults (positive or negative)
• Escape or avoidance of undesired tasks or situations
• Access to preferred activities or items
• Sensory stimulation or regulation

Hypothesis development

• Synthesizes information from antecedent and consequence analysis
• Forms the basis for designing effective behavior intervention plans
• Guides the selection of appropriate replacement behaviors and intervention strategies

Function of behavior

• Escape or avoidance (avoiding tasks, social interactions, or sensory stimuli)
• Attention-seeking (from peers, teachers, or caregivers)
• Access to tangibles or activities (preferred items or experiences)
• Sensory stimulation (meeting sensory needs or preferences)

Testable hypotheses

• Clearly states the relationship between antecedents, behavior, and consequences
• Specifies observable and measurable components
• Formulated as if-then statements (If [antecedent] occurs, then [behavior] will happen, resulting in [consequence])
• Allows for systematic testing and refinement through intervention

FBA vs Functional analysis

• Both methods aim to understand behavior function but differ in approach and intensity
• Selection between FBA and FA depends on behavior severity and resources available
• Understanding differences helps in choosing the most appropriate assessment method

Similarities and differences

• FBA uses naturalistic observation and indirect methods
• Functional analysis involves manipulating variables in controlled settings
• FBA typically less time-intensive and resource-demanding than FA
• FA provides more conclusive evidence of behavior function but may be more disruptive

When to use each

• FBA suitable for most school-based assessments and less severe behaviors
• FA recommended for severe, persistent behaviors resistant to intervention
• FBA often precedes FA if initial interventions based on FBA prove ineffective
• FA may be necessary when behavior function remains unclear after FBA

Conducting interviews

• Interviews provide valuable contextual information and historical perspective

Frequency and duration recording

• Frequency count tallies how often a behavior occurs within a set time period
• Duration recording measures how long a behavior lasts when it occurs
• Combines to provide rate of behavior (frequency divided by observation time)
• Effective for discrete behaviors with clear start and end points

Interval recording

• Divides observation period into equal time intervals (10 seconds, 1 minute)
• Partial interval recording notes if behavior occurred at any point during interval
• Whole interval recording requires behavior to occur throughout entire interval
• Momentary time sampling records if behavior occurs at end of each interval

Data analysis

• Transforms raw observational data into meaningful patterns and trends
• Crucial for developing accurate hypotheses about behavior function
• Combines qualitative and quantitative approaches for comprehensive understanding

Visual analysis techniques

• Graphing data to visually represent behavior patterns over time
