Positive Behavior Support
Positive behavior support is the integration of Valued outcomes Behavioral and biomedical science Validated procedures Systems change
In order to enhance quality of life and prevent problem behavior
![Page 3: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/3.jpg)

Characteristics of PBS
PBS plans can be short or more complicated
Many different intervention choices can result in same positive outcomes
Must fit the values, vision, and resources of those supporting the individual
PBS plans requires team collaboration Purpose is to increase quality of life and
build a team vision
![Page 4: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/4.jpg)

Why individuals Engage in Problem Behavior
If problem behavior is increasing look for events that reinforce it
Problem behavior increases when it is reinforced To obtain attention, access to people, events, or
activities To escape people, events or activities
Problem behavior influenced by physiological variables can occur to escape or obtain internal stimulation
![Page 5: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/5.jpg)
5
Common Functions Maintaining Problem Behavior
To escape from tasks, people, situations, or internal sensations
To obtain attention from staff, peers, or other individuals
To obtain access to preferred items or events To either escape or obtain internal sensations
due to physiological events
![Page 6: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/6.jpg)

First Steps in PBS Process
Medical check-up to ensure there isn’t a health problem or medical issue
Person-centered Planning Establish the team
![Page 7: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/7.jpg)
7
Person-centered Planning
Process for identifying ideal lifestyle Creates a vision for the team Focus on the positive Gathers important information for the
PBS plan Decreases the need for more intensive
interventions Priority and control is given to the
individual
![Page 8: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/8.jpg)
8
Functional Assessment
Identify why the person engages in problem behavior
Assess how to replace problem behavior with desirable behavior
Identify how to redesign the environment to prevent problem behavior
Link all interventions directly to information gathered in the functional assessment
![Page 9: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/9.jpg)
9
Routines, Settings and People Associated with the Occurrence and Nonoccurrence of Problem Behavior
Problem Behavior is Most Likely…
Before work Transitions Sitting next to his
friend John on the way to work
Problem Behavior is Less Likely…
Lunch Small groups Receiving high levels
of attention
![Page 10: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/10.jpg)
10
Developing a Hypothesis Statement
A Good Hypothesis Statement Includes the Following Components:
1. Setting Event
2. Antecedent
3. Problem Behavior
4. Consequences
![Page 11: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/11.jpg)
11
Setting Events
Environmental (noise levels, sitting next to a peer, late to work)
Social (fight during lunch, family crisis) Physiological (sickness, allergies, sleep
deprivation)
![Page 12: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/12.jpg)
12
Antecedent Events (Triggers)
Immediately precedes a problem behavior
Can be related to time of day, people, specific settings, the physical surrounding, or particular activities
Common examples include verbal demands, specific assignments, certain peers or individuals
![Page 13: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/13.jpg)
13
Consequences
An event that is presented contingent upon the occurrence of problem behavior
Common consequences include staff attention, the removal of a difficult task, or the presentation of something the person wants
![Page 14: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/14.jpg)

15
Activity
Complete the hypothesis statement activity in small groups or individually
Write down the setting events, antecedents, behaviors, and consequences described in each vignette
Answer sheet
![Page 16: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/16.jpg)

Types of Functional Assessment Strategies
Indirect assessment methodsDirect observationFunctional analysis
![Page 17: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/17.jpg)
17
Indirect Assessment
Interviewing the person, her parents, staff, and other individuals who know the person well
Record reviews Quality of life measures Checklists and rating scales
![Page 18: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/18.jpg)
18
Identify Routines
The behavior occurs “all the time” is not enough information
Select the most problematic situations and settings
Collect functional assessment information about specific routines
Observe these routines
![Page 19: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/19.jpg)
19
Defining a Problem Behavior
Avoid using a classification label (for example, ADHD, autism, etc)
Describe exactly what the behavior looks like Avoid using vague descriptions (temper tantrums
mean different things to different people)
Make sure the behavior is described in such a way that there is a clear beginning and ending
![Page 20: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/20.jpg)
20
Collecting Direct Observation Data
To help you develop an initial hypothesis To confirm that your hypothesis is
correct To create a baseline that can be used
later to evaluate the PBS plan
![Page 21: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/21.jpg)

Collect a Baseline of Problem Behavior
![Page 22: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/22.jpg)
22
Direct Observational Methods
Measure behavior by frequency, intensity, duration, or latency
Scatter plot “ABC” chart (documents observed
antecedents, behaviors, and consequences)
![Page 23: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/23.jpg)

Outcomes of a Functional Assessment
1. Describe the problem behavior
2. Identify the events, times, and situations that predict when problem behaviors both occur and do not occur
3. Identify the consequences that maintain a problem behavior
4. Develop a hypothesis
5. Confirm the hypothesis using direct observation
![Page 25: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/25.jpg)
25
Functional Analysis
A functional analysis involves observing behavior while systematically manipulating environmental events
A functional assessment includes functional analyses, indirect assessment, and direct observation
![Page 26: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/26.jpg)
26
Activity
In small groups, discuss an individual you currently support
Discuss what you think is maintaining an individual’s problem behavior
What type of information do you have to confirm this hypothesis?
What other evidence do you need?
![Page 27: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/27.jpg)

PBS Planning
![Page 28: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/28.jpg)
28
PBS Plans Must be a Good “Fit”
Values of team membersResources availableSkills and background of those
implementing the PBS planTraining identified as neededUse team based strategies to
identify interventions
![Page 29: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/29.jpg)
29
Team-based Brainstorming
Bring functional behavioral assessment information
Set up flip chart paper for writing down interventions
Set aside time to brainstorm each part of the hypothesis statement
Do not judge ideas during brainstorming Go back later as a team and pick
interventions
![Page 30: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/30.jpg)

33
Examples of Setting Event Interventions
Minimize or eliminate the setting event Design interventions that are implemented
when setting events occur
--Neutralize the setting event
--Withhold or eliminate the antecedent
--Add more prompts for desirable behavior
--Increase the value of reinforcement for desirable behavior
![Page 34: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/34.jpg)
34
Antecedent Interventions
Avoid presentation of antecedent (verbal demand statements)
Modifying Tasks The way activity is completed Functional activities Compensate for skill deficits Initially providing extra support
Create high levels of predictability Offer choices
![Page 35: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/35.jpg)
35
Teaching New Skills
Identify a desirable behavior that will serve the same function as the problem behavior
This new behavior must be more efficient when compared to the problem behavior
![Page 36: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/36.jpg)
36
Consequence Interventions
Are important when teaching new skills (the goal is to make the problem behavior inefficient compared to new behaviors)
Withdraw or terminate reinforcement maintaining problem behavior (extinction)
Withdrawing or terminating reinforcement can result in an “extinction burst” (problem behavior may increase temporarily before decreasing)
![Page 37: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/37.jpg)
37
Examples of Consequence Interventions
Intervene early before problem behaviors increase in intensity (we often ignore early signs that are not as problematic and respond to serious problems)
Redirect person early in the chain of problem behaviors
Avoid engaging in coercive interactions
![Page 38: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/38.jpg)
38
Building a Positive Interaction Pattern
Rapport building strategies Provide 4 positive statements for every
demand or request Deliver reinforcement to persons
immediately when you observe them engaging in positive social behaviors
![Page 39: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/39.jpg)

Evaluating a PBS Plan
A PBS plan should result in… Decreases in problem behavior Increases in academic and social skills Positive lifestyle changes
![Page 50: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/50.jpg)

Collect a Baseline of Problem Behavior
![Page 51: 1 Positive Behavior Support in Community Settings February 3, 2004 Rachel Freeman University of Kansas](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e445503460f94b38380/html5/thumbnails/51.jpg)
51
Examples of Evaluation Measures
Compare the frequency of problem behavior and appropriate behavior
Assess whether the person’s social skills have increased
Observe number of positive interactions that occur during key routines
Changes in the persons quality of life (access to new resources, new friendships)
Assess level of satisfaction with the PBS plan
