What to do when Descriptive Assessment is not Enough
What to do when Descriptive Assessment is not Enough: Choice AssessmentDecember, 2009School Social Worker & School Psychology Discipline DaysObjectiveKnowUnderstand DoThe range and reliability of various behavior assessment practicesWhen a Choice assessment can be helpfulHow to set up a choice assessment for function of behaviorThe differences between a functional analysis and Choice AssessmentUnderstand the disadvantages of functional analysisLink Choice Assessment data to a FBA and BIPAdvantages of Choice Assessment vs. Descriptive AssessmentIncreasing Rigor And Increasing AccuracyChoice Assessment3
Current problems with Indirect and Descriptive methodsIndirect = 30% accurate functions identifiedDescriptive assessments increase accuracy (60 80%) Steege and Northup, Journal of Proven Practice 1998Positive bias to attention in a school setting (Iwata)May appear to be Escape to Attention when the student might really be Escape
Functional AnalysisIn General:Set up situations that allow you to compare conditionsAttentionDemandAlonePlayTake data on the problem behaviorReliability and Validity are highConsidered the Gold StandardFunctional Analysis Video

If it is the Gold Standard, why arent we doing more Functional Analysis?Potential risk to individualelicit the behaviorComplexRequires control over environmentHard to do it with elopement, low frequency behaviorsRequires extensive Supervised ExperienceIf you believe a Functional Analysis is needed contact the CBAT1. requires extensive, supervised experience to implement (currently, I'm the only person at Heartland who should be doing them independently)2. involves attempts to reinforce problem behavior to demonstrate experimental control. this should not be used lightly when we have other less intensive means of forming hypotheses, including fbas and progress monitoring bips.10
Paired Choice Assessment for FunctionAlso called Contingent Operant AssessmentIdentifies relative preferencesCan be done in a Classroom SettingIncrease Teacher buy-in of function3/4 determined the same function as Functional Analysis (Berg, Wacker, 2007) Not intended to elicit problem behaviorCan be used for students with low frequency problem behavior.11What is the difference?Functional AnalysisIdentifies conditions that will increase problem behaviorsMost reliable methodControls for attentionVery controlled environmentPaired ChoiceIdentifies student preferences3/4 indicated same function as FAControls for attentionCan be done in a classroomWhat do I get from it?Information about antecedents that are more likely to produce positive behaviorLikely to gain confirmation of functionManage the influence of attentionCan get information on preferred materials, items, settings, tasksMay take less time than a comprehensive descriptive analysis Paired choice min. of 25 to 30 minDescriptive assessment min of 3 20 min observationsHow do I set up the space?2 age appropriate spaces (tables)3 to 5 feet apartDifferent choices placed on each tableEach session is 5 min.Break between sessions
Where can the space be set up--back of the classroom,Childs desk areaInterview with an older student14What are the rules?AdultAdult explains options beforeThe choice is repeated every 90 seconds for 5 minutesAdult responds to child as indicated in the condition
ChildStarts between the tablesIs Free to move between both tablesCant take toys back and forth
If the behavior is mildPrompt the child to make a choiceIf the behavior is severeEnd the sessionConsider other assessment techniquesWhat happens if the child demonstrates the problem behavior?5 min.

What data should I collect?10 sec. Partial Interval RecordingRecords which side of the midpoint the student is standing during each intervalIf student was in both sides, record the one that the student spent the most timeStanding on the midline is not recordedDuration RecordingRecord total time on each side
Refer to the data sheet.21
Escape Profile (Berg et al., 2007)Child wants to be alone with or without toysAbby, a 12-year-old girl, had been referred for noncompliance to requests and hitting others.
Handout with the 4 student graphs from the Berg et al., 2007 article.22Escape Profile (Berg et al., 2007)
Child wants to be alone.But will tolerate Attention paired with Toys.Jack (19 years old), had been referred forself-injury, aggression, and noncompliance23
Attention Profile (Berg et al., 2007)Higher Problem BehaviorsPrefers Attention,Less PB when not paired with a DemandWarren had higher problem behaviors in the Attention and Demand condition over the attention only and attention with toys conditions---but he would still rather do this than being alone.Warren, a 15-year-old boy, had been referredfor aggression and property destructionHeartland AEA24
Not Fail Proof(Berg et al., 2007)Lyles functional analysis indicates that problem behavior is reenforced by escapeBut Lyle would often time picks attention being alone with nothing, or alone with toys but her prefers being alone if it is just attention and nothing.
During choice problem behavior occurred during 8/10 sessions for an average of 10% of intervals.
Lyle (18 years old)and Jack (19 years old), had been referred forself-injury, aggression, and noncomplianceHeartland AEA25LyleProblem Behavior was maintained/reinforced by escape from demandsChoice was maintained/reinforced by positive reinforcement such as teacher attentionChoice Assessment based instructional strategies reduced the problem behavior and Functional Analysis based strategies eliminated the problem behavior. What if I want to know more than just what the child prefers?Collect more dataProblem behaviors during choice activityEngagement or compliance while in preferred setting
Compare reinforcer choices or demand choices.27
Paired ChoiceSimplifiedWendy to add video of dog doing choice task (treat 1 vs treat 2; toy 1 vs toy 2; treat 1 vs toy 1) 28Paired Choice: Hypothesized FunctionsFind a partnerGo to the following SurveyMonkey link:http://www.surveymonkey.com/s/2B8BD2RConsider the possible function in each scenario to answer each item
We will go over each item at the end of the activity.29How can Paired Choice reduce time spent on FBA summaries?30-60 minutes compared to multiple observations in multiple settingsMay choose to do a paired choice assessment early in problem analysis when escape and gain are both present as consequences for problem behavior.Some observation for problem identification 30How can Choice Assessment be used to complete an FBA summary?(Graph from Berg et al., 2007)
Warren: Choice Assessment ResultsAggression and property destructionWarren chose teacher attention consistentlyProblem behaviors: 36% of the intervals with attention and task demand0-5% with attention or attention with toysChose attention with demands over alone with toysHe engaged in the leisure, attention and tasks a median of 81% of intervalsDirect observations during independent work tasks and leisure time alone show he has appropriate behavior for about 1 minute prior aggressing
Warren is 15 years old
Warren chose teacher attention consistently even when the attention included task demands32Warren: FBA Summary ComponentsFunction of Problem Behavior: Gain AttentionSummary Statement: When Warren is left alone in leisure or independent work he is more likely to aggress or have property destruction to gain attention from adults.Antecedent: When left aloneConsequences: Gain Attention33Warren: FBA Summary ComponentsSummary Statement: When Warren is given demands and leisure time paired with adults he is more likely to engage in the activities appropriately and has less aggression.Antecedent: When le
