Title: Assessment and Treatment of Severe Problem Behaviors
1Assessment and Treatment of Severe Problem
Behaviors
- Joel E. Ringdahl, Ph.D.
- The University of Iowa
2Objectives
- Learn the differences between various behavior
assessment - Learn the reinforcers instrumental in maintaining
problem behavior - Learn typically implemented behavior change
techniques - Learn the link between assessment and treatment
3Behavioral Terms
- Positive reinforcement presentation of a
stimulus results in an increased probability of
the behavior - Negative reinforcement removal of a stimulus
results in an increased probability of the
behavior - Note both positive and negative reinforcement
indicate an increased likelihood of behavior, the
difference is in the presentation or removal of a
stimulus - Punishment presentation or removal of a
stimulus results in a decreased probability of
the behavior - When addressing behavior problems,
reinforcement-based approaches allow for most
consistent results
4Goals of Behavioral Assessment
- First Provide prescriptive information
regarding treatment - Second Identify under what conditions the
behavior is most likely to occur - Third Identify the specific reinforcers
maintaining problem behavior - Identification of the relevant reinforcers can be
achieved through a variety of methods
(descriptive or experimental)
5Types of Assessment
- Descriptive Assessment
- Informal observation
- No direct manipulation of the environment
- Experimental Assessment
- Formal observation
- Direct, systematic manipulation of variables in
the environment
6Behavioral Assessment Experimental Method
(Functional Assessment/Functional Analysis)
- A process for gathering information that can be
used to maximize the effectiveness and efficiency
of behavior support (Five steps) - A clear description of the problem behavior
- Identification of antecedents (events, times,
situations) - Identification of consequences that occur after
problem behavior - Hypothesis development
- Hypothesis verification (functional analysis)
7Why do a Functional Assessment?
- Increase the probability that the developed
intervention will work. - Help identify the appropriate intervention.
8When Should it Be Conducted?
- By law, a functional behavioral assessment must
be conducted and behavioral intervention plan
implemented prior to removal of a student from a
particular placement (IDEA, 1997). - In practice, a functional assessment should be
conducted before the implementation of any
behavior change program.
9What Behaviors Are Appropriate for Assessment
- ADHD behaviors
- Severe problem behaviors
- aggression
- self-injurious behavior
- pica
- Tantrum behavior
- Among others

11Possible Functions
- Positive Reinforcement (Gain)
- Attention (either from adults or peers)
- Preferred activities or items
12Case Example 1 Jack
- 4 years old
- Autism severe mental retardation
- Referred for assessment and treatment of
aggressive behavior (pulling mothers hair) - No appropriate communicative strategies
13(No Transcript)
14Possible Functions Continued
- Negative Reinforcement
- Escape or avoidance of nonpreferred activities
(e.g., chores, homework) - Escape or avoidance of aversive situations (e.g.,
social contact, appointments)
15Case Example 2 Calvin
- 10 years old
- Pervasive developmental disorder mild/moderate
mental retardation - Referred for assessment and treatment of
aggression and noncompliance - Communicated through speech
16Behavior maintained by negative reinforcement
(escape)
17Possible Functions Continued
- Automatic reinforcement Behavior occurs
independent of the social environment - Automatic positive reinforcement produces some
sort of pleasurable sensory outcome - Automatic negative reinforcement alleviates some
aversive physiologic condition
18Case Example 3 Mark
- 15 year old young man
- Autism severe/profound mental retardation
visual impairment - Referred for assessment and treatment of
self-injurious behavior (head and body hitting) - No communicative behavior

20Case Example 4 Bill
- 16 year old young man
- Mild/moderate mental retardation
- Referred for assessment and treatment of
stereotypic (i.e., repetitive) hand flapping - Communicated through speech
21Behavior maintained by automatic reinforcement (B)
22Treatment Options
- Withhold the functional reinforcer (extinction)
- Provide free access to the reinforcer
(noncontingent reinforcement) - Provided response-dependent access to the
reinforcer (differential reinforcement)
23Treatment Options Extinction
- Extinction Behavior no longer results in
identified reinforcer. - Drawbacks include potential increase in intensity
of problem behavior and variation in topography
access to the reinforcer is limited does not
teach a new behavior. - Extinction is seldom used as a sole component of
treatment.
24Treatment Options NCR
- Noncontingent reinforcement Functional
reinforcer is provided independent of behavior. - () Reduces motivation for problem behavior
eliminates side effects associated with
extinction simple to implement. - (-) Does not teach a new behavior might
accidentally reinforce problem behavior.
25Treatment Options Differential Reinforcement
- Differential reinforcement Reinforcer available
contingent on communication (i.e., functional
communication training). - () Reduces side effects associated with
extinction provides access to the reinforcer
teaches a new behavior. - (-) Can be difficult to implement individual
might spend a lot of time with the reinforcer.
