1 Chapter 24: Functional Behavior Assessment
Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

2 Functions of Problem Behavior
Positive Reinforcement “Getting something” Negative Reinforcement “Getting out of something” These functions can be Socially mediated Non-socially mediated (automatic) Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

3 Positive Reinforcement
Social Attention from others Access to tangible stimuli Automatic Physical Stimulation Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

4 Negative Reinforcement
Social Escape from aversive or difficult tasks Automatic Escape from aversive stimulation Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

5 Function vs. Topography
Topography = form of the behavior Function = function of the behavior Different topographies of problem behavior Can serve the same function Can serve different functions Similar topographies of problem behavior Function is more important for intervention than form Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

6 FBA and Intervention When the function of problem behavior has been identified, intervention can consist of: Altering antecedent variables Altering consequent variables Teaching alternative behaviors Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

7 Altering Antecedent Variables
Change and/or eliminate Motivating operation for problem behavior Discriminative stimuli that trigger problem behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

8 Altering Consequent Variables
Place problem behavior on extinction Withhold identified reinforcer when problem behavior occurs Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

9 Teaching Alternative Behaviors
Select appropriate behaviors that serve the same function Provide reinforcer that previously maintained problem behavior contingent upon the new, alternative behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

10 FBA and Default Technologies
Intrusive, coercive, or punishment-based interventions Often selected arbitrarily Understanding why a behavior occurs suggests how it can be changed Conducting FBAs and understanding why a behavior occurs decreases reliance on default technologies Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

11 FBA and Prevention of Problem Behavior
When default technologies are used, other problem behaviors may emerge The use of FBA for developing intervention may avoid the development of new problem behaviors FBA may identify conditions that pose risks for the development of future problem behaviors Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

12 Continuum of FBA Methods
Analog functional analysis Level of Precision Level of Difficulty Direct observation in natural routine Indirect Assessments Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

13 Functional (Experimental) Analysis
Antecedents and consequences are arranged so that their separate effects on problem behavior can be observed and measured Often referred to as analog Similar to what is occurring in natural routine, but more systematic Allows for better control Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

14 Typical Conditions Contingent attention Contingent escape Alone
Control (e.g., “free play”) These are presented one at a time until a pattern of problem behavior emerges Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

15 Interpreting Functional Analyses: Attention Function
Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

16 Interpreting Functional Analyses: Escape Function
Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

17 Interpreting Functional Analyses: Automatic Reinforcement
Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

18 Interpreting Functional Analyses: Undifferentiated Pattern
Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

19 Advantages of Functional Analysis
Yields a clear demonstration of the variable(s) that relate to the occurrence of problem behavior Serve as the standard to which all other forms of FBA are evaluated Enable the development of effective reinforcement-based treatment Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

20 Limitations of Functional Analysis
May temporarily strengthen the problem behavior May result in the behavior acquiring new functions Acceptability may be low Difficult to use for serious, low frequency behaviors If conducted in contrived settings, may not identify idiosyncratic variables related to problem behavior Requires time, effort, and professional expertise Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

21 Descriptive FBA Direct observation of problem behavior under naturally occurring conditions Events are NOT arranged in a systematic manner Different Forms ABC Continuous Recording ABC Narrative Recording Scatterplot Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

22 ABC Continuous Recording
Occurrences of targeted problem behaviors and Selected environmental events Within the natural routine During a specified period of time Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

23 Sample ABC Continuous Recording Form
Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

24 Advantages of ABC Continuous Recording
Uses precise measures Provides useful contextual information and correlations regarding environmental events and the problem behavior, which can provide useful information for later functional analyses Does not require disruption of the individual’s routine Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

25 Limitations of ABC Continuous Recording
Often, antecedents and consequences do not reliably precede and follow problem behavior, making correlations difficult to detect May use conditional probabilities Proportion of occurrences of problem behavior preceded by a specific antecedent Proportion of the occurrence of problem behavior followed by a specific consequence These may be misleading, however Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

26 ABC Narrative Recording
Data are collected only when behavior(s) of interest are observed Recording is open-ended Thus, it is less time-consuming than continuous recording Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

27 Sample Narrative Recording Form
Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

28 Limitations of ABC Narrative Recording
Utility in identifying behavioral function not established May yield false positives because data are collected only when problem behavior occurs The same antecedent and consequent events may be present when problem behavior is absent Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

29 Limitations of ABC Narrative Recording
Reliability may be low Unless trained, observers may report “inferred states” rather than events It is often difficult to discriminate which environmental events actually occasion the problem behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

30 Scatterplot Procedure for recording the extent to which a target behavior occurs more often at particular times than others Divide day into blocks of time (e.g., a series of 30-min segments) For each time period, enter a symbol to indicate whether problem behavior occurred a lot, some, or not at all Analyze for patterns to identify temporal distributions of behavior and events that occur at that time Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

31 Sample Scatterplot Cooper, Heron, and Heward
Applied Behavior Analysis, Second Edition

32 Advantages of Scatterplots
Identify time periods during which the problem behavior occurs Can be useful for pinpointing periods of the day when more focused ABC assessments can be conducted Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

33 Limitations of Scatterplots
Utility of scatterplots is unknown Subjective in nature Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

34 Indirect FBA Structured interviews Checklists Rating scales
Questionnaires These are all considered “indirect” because they do not involve observing the behavior; rather they involve soliciting another’s recollection of the behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

35 Structured Behavioral Interviews
Goal: to obtain clear and objective information about the problem behavior(s), antecedents, and consequences, as well as a plethora of other information Several published examples Interview significant others Interview student him/herself Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

36 Behavior Rating Scales
Ask informants to estimate the extent to which behavior occurs under specified conditions Hypotheses about function of behavior are based on scores associated with each condition Those conditions with the highest score are hypothesized to be related to the problem behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

37 Advantages of Indirect FBA
Useful source of information for guiding subsequent, more objective assessments Contribute to hypothesis development regarding the variables that may occasion or maintain problem behavior Very convenient because they do not require direct observation of behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

38 Limitations of Indirect FBA
Informants may not be accurate Informants may be biased Little research exists to support the reliability of information obtained from indirect assessments Not recommended as principal means of identifying functions of behaviors. Best used for hypothesis development. Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

39 Conducting an FBA Gather information via indirect and descriptive assessments Interpret information and formulate hypotheses Test hypotheses using functional analysis Develop intervention options based on the function of problem behavior Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

40 Gathering Information
Conduct functional assessment interview with individual’s care providers Use this information to define target problem behaviors, identify and define potential antecedents and consequences, and to determine what other assessments are warranted Conduct direct observations of the problem behavior within the natural routine Use this information to confirm/disconfirm information obtained in interviews Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

41 Interpreting Information and Formulating Hypotheses
Write hypothesis statements in ABC format Antecedent Behavior Consequence When Tonisha is prompted to wash her hands in preparation for lunch, she screams and tantrums, which is followed by… termination of hand washing and lunch by being sent to time-out. Hypothesized function = escape from hand washing or lunch Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

42 Testing Hypotheses Conduct a functional analysis
Always include a control condition Select additional conditions depending upon hypotheses If positive reinforcement (attention) is a hypothesis, conduct contingent attention If negative reinforcement is a hypothesis, conduct contingent escape If automatic reinforcement is a hypothesis, conduct alone condition Alternate conditions in counterbalanced fashion until a pattern emerges Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

43 Brief Functional Analyses
Conducting a functional analysis in a short period of time Procedure Implement one session of the control condition Implement one session of each test condition Implement a contingency reversal Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

44 Contingency Reversal Used to confirm hypothesis by:
Providing reinforcement for an alternative behavior Problem behavior no longer produces reinforcement Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

45 Sample Brief Functional Analysis with Contingency Reversal
Esc. for Req. Esc. for Req. Control Cont. Attn. Cont. Esc. Cont. Esc. Rate of Behavior per Min 3 2 1 4 Requests Problem Behavior 1 2 3 4 5 6 Sessions Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

46 Developing an Intervention
FBA does NOT identify the interventions that will be effective DOES identify powerful reinforcers that can be used in intervention Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

47 Functional Equivalence
Intervention must match the function of the problem behavior If problem behavior = escape function Intervention should provide escape for alternative behavior OR alter task demands to make escape less reinforcing Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

48 Functional Equivalence
Intervention must match the function of the problem behavior If problem behavior = gain function Intervention should provide desired outcome (access to attention or tangibles) for alternative behavior OR alter antecedent conditions to make attention and/or tangibles less reinforcing Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

49 Alter the ABC Contingency
Antecedent Behavior Consequence Attention in the form of a reprimand and discussion. When Deshawn is left alone with toys or work… He hits others, which is followed by… Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

50 Alter the Antecedent Antecedent Behavior Consequence
When Deshawn is left alone with toys or work… He hits others, which is followed by… Attention in the form of a reprimand and discussion. Deshawn is provided with a peer buddy during work/play periods These are irrelevant because problem behavior is avoided. Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

51 Alter the Behavior Antecedent Behavior Consequence
Attention in the form of a reprimand and discussion. When Deshawn is left alone with toys or work… He hits others, which is followed by… Deshawn is prompted to ask a peer or adult to play/help, which is followed by… Attention in the form of socialization and help. Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

52 Alter the Consequence Antecedent Behavior Consequence
Attention in the form of a reprimand and discussion. When Deshawn is left alone with toys or work… He hits others, which is followed by… Neutrally blocking the hitting and ignoring Deshawn. Cooper, Heron, and Heward Applied Behavior Analysis, Second Edition

53 Summary Prior to intervention When designing intervention
