1 PAAL Training FBA Kaori G. Nepo, M.Ed., BCBA

2 FBA: Functional Behavior Assessment
To create hypotheses about the functional relationship between environmental stimuli-behaviors Why? Avoid/Eliminate ineffective interventions To develop effective interventions Ensure the effectiveness of interventions

3 Three Term Contingency
A(SD) – B(R) – C(SR+/SR-/SP+/SP-) Antecedent: a stimulus which occurs before a behavior Behavior/ Response: movement or action by an individual Consequences: a stimulus which is produced by a behavior

4 Four Term Contingency MO A-B-C
Motivating Operation (MO): the environmental changes that alter the reinforcing value of stimulus (and the frequency of a behavior) EO: Establishing Operation AO: Abolishing Operation

5 Function vs. Topography
Function: purpose of behaviors Topography: how the behavior looks like Behaviors look same but different functions C.f. tantrums for attention or escape Behaviors look different but same functions C.f. manding

6 Function Positive Reinforcement: SR+ Social Attention Tangible
Automatic Positive Reinforcement Negative Reinforcement: SR- Social Negative Attention (Escape/Avoidance) Automatic Negative Reinforcement Sr+ Praise or reprimand Toy, food, tokens… Visual, tactile, olfactory, auditory, taste Sr- Reprimand Task/demands Activities Social interactions Settings Sensory (noise, smell, touch, visual, taste)

7 Assessment vs. Analysis
Gather information Form hypotheses Not systematic arrangement of environmental stimuli Natural settings Use information Test hypotheses Systematic manipulation of environmental stimuli Contrived/simulated settings

8 Conduct FBA Operational Definition of the target behavior and measurement Gather information (indirect and direct assessment) Interpret information Test hypothesis (Behavior Analysis) Develop interventions

9 Operational Definition
: define the target behavior…. Objective: Observable and measurable Clarity: unfamiliar observers can identify Including clear description of topography Completeness: clear boundaries, time frame Beginning and ending IRT/ break between behaviors Objective: Clarity: head hitting..hit his forehead with his palm from at least a foot away Completeness: c.f. duration..No more than 2 seconds interruption,

10 Data Collection Direct Measurement Direct Observational Recording
Permanent Products (written sample) Direct Observational Recording Event Recording Duration Recording Latency Recording Inter Response Time (IRT) Interval Recording (whole or partial) Momentary Time Sampling

11 Gather Information Indirect FBA Direct observation What to look for…
Standardized test Medial history Maladaptive behaviors Setting, triggers, reinforcers Social history Previous FBA/interventions

12 Indirect FBA Collect useful information from individuals and/or significant others through… Interview Checklists Rating Scales Questionnaires Record review

13 Indirect FBA Advantage: Limitation: Convenient
Can collect useful information to form hypotheses Limitation: Accuracy Subjective Biased Not data based Low IOA

14 (Direct) Descriptive FBA
ABC Continuous Recording ABC Narrative Recording Scatter Plots

15 (Direct) Descriptive FBA
Direct observation in the natural environments Advantage: Collect useful information in the context Do not interrupt routines Limitation: Difficulties to pinpoint correlation May be misleading (c.f. intermittent reinforcement) Accidental correlation ABC Continuous Recording ABC Narrative Recording Scatter Plots

16 Example Jon is 12 years old and diagnosis with attention deficit/hyperactivity disorder and autism. He attended both regular education classrooms and a special education classroom with one-on-one aide. He exhibits “chin hitting” across environments. ABC assessment was conducted in both environments and it was found that he is most likely to exhibit chin hitting during difficult tasks and in larger classrooms. Operational Definition

17 ABC Recording Time Antecedents Behaviors Consequences 8: 15
Given demands Chin hitting Tasks removed 9:30 Given demands in regular class Task removed Attention provided 9:35 Teacher called on other students 9:52 Group instruction Getting off seat Redirection from teacher 10:14 Changes in schedule Given less familiar demands

18 Interpret Information
Draw hypotheses from information collected Write in ABC format Hypotheses Antecedent Behavior Consequence Escape from difficult tasks When Jon is given difficult tasks He hit his chin with his fist Tasks being removed Contingent Social Attention When teacher attention diverted from Jon Teacher attends to Jon

19 Behavior Analysis Experimental manipulation of antecedents and consequences to test hypotheses Advantage: Clear demonstration of relation among variables Limitation: Temporarily reinforce maladaptive behaviors Counterintuitive Not effective for less frequent behaviors Contrived settings Time consuming

20 Behavior Analysis Possible functions based on functional behavior assessment (c.f. contingent attention, contingent escape, alone, access to reinforcers) each condition will be presented systematically one at a time and collect data on target behaviors Create graphs Visually inspect graphs

21 Examples Motivating Operation (MO) and Reinforcement Contingencies for functional analysis Condition Antecedents (MO) Consequences Control Preferred activities/ Attention are provided No demands Ignored or redirected Contingent Attention Attention is withheld or diverted Attention is provided Contingent Escape Demands are given Remove demands/ tasks Alone No demands, no materials, no teacher Ignored

24 Examples

25 Examples

26 Develop Interventions
Alter Antecedents Change MO Change SD Alter Consequences SR+ SR- Teach or replace with functionally equivalent behaviors Examples Altering task demands to make escape less reinforcing no time out for escape no reprimands or discussions for attention seeking behaviors Monitor effectiveness-changes in its functions

27 FBA example Tommy is 15 years old male student who is diagnosed with autism. He is non-verbal and use signs and pictures to communicate his needs with occasional prompts. Tommy exhibits whining (high pitch and non-contextual vocalization) across settings and people, but more likely with his mother. Interview and ABC Continuous Recording Data suggested that he is more likely to exhibit whining when his mother is talking with others.

28 FBA Form Hypotheses Hypotheses Antecedents Behaviors Consequences
Escape from demands When Tommy is given demands He whines (high-pitch, non-contextual vocalization) Demands being removed Contingent attention when his mother is present He exhibits whining Attention being provided Contingent positive reinforcement (tangible) In the presence of reinforcers and mother He receives tangible reinforcers

29 Test Hypotheses

30 Develop Interventions
Contingent Tangible DRI/DRA (verbal/non-verbal) DRO NCR Contingent Attention DRI/DRA (verbal/non-verbal) Extinction Shaping, prompting, errorless learning, discrete trials, token economy,

31 Review #1 What is FBA? Functional Behavior Assessment

32 Review #2 Behavior Analysis is different from Functional Behavior Assessment because… Experimental manipulation Use information vs. gather information Test hypotheses Contrived settings/ interruption of routines

33 Review #3 Examples of indirect FBA are… Interview Checklists
Rating Scales Questionnaires Record review

34 Review #4 What are some of limitations of Indirect FBA? Subjective
Accuracy Biased Low IOA Not data based

35 Review #5 Examples of (Direct)Descriptive FBA are...
ABC Continuous Recording ABC Narrative Recording Scatter plots

36 Review #6 What are advantages of (Direct) Descriptive FBA?
Collect useful information in the context Do not interrupt routines

37 Review #7 Explain how to test hypotheses…
Systematic manipulation of environmental stimuli (antecedents and consequences) Graphing Visual inspection

38 Review #8 Why is it necessary to conduct FBA?
Avoid/Eliminate ineffective interventions To develop effective interventions Ensure the effectiveness of interventions

39 Review #9 What are functions of behaviors? Positive Reinforcement SR+
Social Attention Tangible Automatic Positive Reinforcement Negative Reinforcement SR Social Negative Attention (Escape/Avoidance) Automatic Negative Reinforcement

40 Review #10 Explain Three Term Contingency… A(SD) – B(R) – C(SR+/SR-/SP+/SP-) Antecedent: a stimulus which occurs before a behavior Behavior/ Response: movement or action by an individual Consequences: a stimulus which is produced by a behavior
