Classroom-Based Functional Assessment Utah State University Effective Practices Conference 2009 Tyra Sellers, BCBA
A Question For You… Why is it important to identify the function of a behavior problem?
Functional Behavior Assessment (FBA) • What is it? • When is it required? • Severe behaviors requiring a Behavior Intervention Plan
Review of Terms • Operational Definitions • Antecedent • SDs • MO’s: can change the value of the consequence • Consequence • Positive versus Negative • Reinforcement • Punishment
Review of Functions Gain Access –attention, tangible Escape –demands (social/work), environmental conditions Automatic –internal states/sensations Multiply Maintained All behavior is a function of its consequences.
Types of FBA Methods • Indirect Functional Behavior Assessment • Information gathered from sources, no direct observations • Descriptive Functional Behavior Assessment • Information gathered from direct observations in naturally occurring settings • Functional Analysis (Experimental) • Information gathered from direct observations in experimentally controlled settings
Indirect Functional Behavior Assessment • Gather information from multiple sources • E.g., teacher, parents, siblings, care givers, DIS personnel, peers, target child him/herself, records • Use structured tools • E.g., interview forms, questionnaires, checklists • Use unstructured tools • E.g., open interviews
Indirect Functional Behavior Assessment Cont’ • Interview Goals: • Objective and descriptive info re: problem behavior, antecedents, consequences • When, where, with whom, how often, how long, how much intensity, what happens right before, what happens immediately after • Specific, clear, and free from your influence or bias • No interpretation or inferences
Indirect Functional Behavior Assessment Cont’ • Benefits • Info from people familiar with student • Info related to inaccessible events/settings • Can help guide/structure next steps and save time • Limitations • Accuracy of information • Biases and perceptions • Research has shown low validity and inter-rater agreement
Descriptive Functional Behavior Assessment • Directly observe student in natural setting(s) • ABC Narrative –written descriptions, record only when the behavior occurs • ABC Continuous –record specific information (usually a checklist) regarding the antecedents, behavior, and consequences during a specific period of time • Scatterplot –record frequency of occurrences related to specific times of day, days of the week, or other common events (e.g., regular classroom activities)
Descriptive Functional Behavior Assessment Cont’ • Benefits • Can show correlation that may describe causal relationships • Does not rely on memory • Reduced risk of bias • Minimal disruption to classroom routine, no disruption to student’s routine • Limitations • Narrative forms –potential for inaccuracies and bias • Staff may perceive as difficult to manage • May require long data collection period (e.g., 2 weeks)
Descriptive Functional Behavior Assessment Cont’ • Use information from indirect methods • When • Where • With whom • How often • Decide on data collection method • What kind • What to include (may need to modify) • How often (event, interval, momentary sampling) • Who collects
Descriptive Functional Behavior Assessment Cont’ • Practice using narrative ABC Data form and DA Card • Target Behaviors: • Hitting table: hitting table with one or both open hand(s) • Throwing Objects: throwing any object • Property Destruction: breaking, ripping, or otherwise destroying any property
Descriptive Functional Behavior Assessment Cont’ • How to use descriptive data • For EACH BEHAVIOR • Tally the number of antecedents that preceded • Tally the number of each consequence that followed • Make a bar graph
Descriptive Functional Behavior Assessment Cont’ WHY GRAPH??? COMPARE Antecedents: Asked to stop prf’d = 25 Denied rqst = 20 Asked to do = 2 One-on-One = 0 Group = 0
Descriptive Functional Behavior Assessment Cont’ • Analyzing Data • Look for patterns of relationships between behavior and specific environmental events • Antecedents and behavior • Behavior and consequences • When does it occur? • When does it not occur? • Make a hypothesis about the function based on data
Descriptive Functional Behavior Assessment Cont’ • Questions to ask • Characteristics of antecedents/consequences? • What do antecedent/consequences have in common? • In what ways do they differ? • Do I need more specific information?
Descriptive Functional Behavior Assessment Cont’ When analyzing, remember: Objective No inferences Quantity Quality
Practice Analyzing Data Hypothesized Function?
Practice Analyzing Data First impressions?
Practice Analyzing Data Hypothesized function? What other info would help?
Practice Analyzing Data Did this help confirm/refine hypothesis?
Writing an FBA • Identifying information (about student and you) • How data was collected • Graphs, if you have them • Summaries of data • High frequency • Low frequency • Hypothesis of function • District form versus written report
What To Do With an FBA • Informs Behavior Intervention Plan • How to arrange environment to reduce/prevent • How to respond when target behavior occurs • What replacement behaviors to teach • Informs general teaching and parenting strategies
How To Tell If Your Hypothesis Was Correct • Implement intervention • Take data • Does target behavior decrease? • If it does not, consider: • Extinction bursts • Learning history • Other sources of reinforcement
Cookie Cutter vs. Individual Functionally Matched Interventions • Cookie Cutter • Pros • Cons • Individual Functionally Matched
FBA and BIP Analysis • Read the following scenario. Answer these questions: • What was the hypothesized function? • Why did the teacher end up making that hypothesis? • Was it reasonable? • What was the functionally matched intervention? • Was it effective in reducing the problem behavior? • What more information would you like? • What might you change about the intervention?
FBA and BIP Analysis Scenario Sammy is a preschooler with autism. He receives direct 1:1 instruction for most of his day, but participates in circle time with his other 12 classmates. Staff report that group time is not preferred for Sammy. ABC/DA data indicated that Sammy frequently hit the nearest peer on the head or shoulders during circle time. The teacher implemented an intervention plan where the aggression is physically blocked by an aide seated near him. The aide then pulls Sammy’s chair 5-10 feet back from the group, next to the aide, and sits quietly for 30 seconds. Instances of hitting experienced a slight, but steady increase following intervention that maintained for 2 weeks.
When To Call In A Specialist? • After you have: • Conducted an FBA • Tested hypothesis • Made revisions • Revised hypothesis and/or intervention • Problem behavior continues to maintain or increases • Or, if: • The problem behavior is very dangerous • There seem to be multiple complex functions (e.g., result of descriptive assessment unclear) • The appropriate intervention requires a specialist
Functional Analysis (Experimental) • Systematic presentation of antecedents and consequences • Generally in contrived, controlled setting • Typically consist of 4 conditions (three test and one control) -Demand/escape -Alone -Attention -Play (control) • Measure frequency of target behavior(s) across conditions
Functional Analysis (Experimental) • Benefits • Experimental control • Typically clear demonstration of controlling/maintaining variables • Allows for more precise intervention • Backed by empirical research • Limitations • Potentially strengthen target behavior during assessment • Negative perceptions • Contrived setting • Time, staff, training requirements
What To Do While Collecting FBA Data Neutral, limit attention Keep demands in place Intermittent praise for appropriate behavior
