Title: Behavioral Assessment: Initial Considerations
1Chapter 20
- Behavioral Assessment Initial Considerations
2Behavior Modification Program Phases
- Screening/Intake
- Presenting concerns
- Agency Policies
- Crisis screening
- Diagnosis (insurance)
3Behavior Modification Program Phases (cont.)
- Baseline Phase Assess behavior quantitatively
(frequency, duration, etiology severity, quality,
environmental controls). - Treatment Phase Design a program using the
tools weve learned thus far. Assess success,
redesign if necessary and fade stimuli/reduce
consequences to bring behavior under control of
natural reinforcers. - Follow-up Phase See if behavior maintains,
adjust natural reinforcers or begin treatment
again.
4Indirect Assessment Procedures
- Interviews with the Client and Significant Others
(See Table 20-1) - Rapport
- Non-judgmental
- Confidentiality
- Set target behaviors
5Indirect Assessment Procedures (cont.)
- Questionnaires
- Life History
- Survey
- Rating scales and checklists (CBCL, Conners,
BASC, etc.)
6Indirect Assessment Procedures (cont.)
- Role Playing ( to assess behavior in office).
- Information from Consulting Professionals.
- Client Self-Monitoring ( not as good as trained
observers).
7Direct Assessment Procedures
- More accurate but more time consuming and thus
costly. - Covert behaviors not observable.
8Experimental Assessment Procedures
- Experimental functional analysis See Chap 22
9DATA Why Bother?
- To Determine whether behavioral treatment is
appropriate. - Maybe the behavior isnt in your area of
expertise. - Maybe the behavior is not really a problem.
- Data can lead to treatment by discovering
controlling environmental variables.
10DATA Why Bother? (cont)
- To see if Treatment is working.
- To prompt and/or reinforce the treatment
providers. - Counting behavior may impact its frequency apart
from treatment effects. Reactivity is the effect
of being watched (keeping track of weight
loss/gain, exercise, etc. can be motivating).
11Chapter 21
- Direct Behavioral assessment What to Record and
How
12Characteristics of Behavior to be Recorded
- Topography
- Amount
- Rate/frequency.
- Frequency graphs. Pg. 271
- Cumulative Graphs pg. 273
- (If comparing more than one behavior
and/or rate changes are small)
13Characteristics of Behavior to be Recorded (cont.)
- Duration
- Intensity (may need instrumentation such as
voice meter). - Stimulus Control What in the environment PROMPTS
the behavior? - Latency between stimulus and response.
- Quality just an arbitrary rating along one of the
previously listed quantitative dimensions.
14How to Record Behavior
- Continuous recording every instance
- Interval recording
- Partial interval recording maximum one instance
within a specified time interval. - Whole interval recording record only if the
behavior persists throughout the entire interval. - Time-Sampling Recording intervals are separated
by longer periods of time to save time in
sampling.
15Assessing Accuracy of Observations
- Response definition may be vague.
- Observational situation may be difficult to
detect behavior. - Observer may be poorly trained.
- Data Sheets/recording procedures may be poorly
designed.
16Assessing Accuracy of Observations (cont.)
- Interobserver Reliability (IOR) 80-100
acceptable - Frequency recordings
- smaller number
- larger number X 100
- Interval recordings
- of intervals agreed
- intervals either observer recorded a
behavior X 100
17Chapter 22
- Functional Assessment of the Causes of Problem
Behavior
18What is Functional Analysis?
- Examination of the relationship between behavior
and its antecedents and consequences - Antecedents
- eliciting stimuli
- Consequences
- Positive or negative reinforcement
19Types of Assessment
- Questionnaire
- Completed by those familiar with client
- Reliability issues
- Observation
- Observe what is going on
- Form hypotheses about antecedents and
consequences
20Types of Assessment
- Functional Analysis
- Systematic manipulation of environmental events
to experimentally test their role in behavior
maintenance - Limitations
- Infrequent behaviors
- Not applicable in dangerous behaviors
- Expensive and time consuming
21Causes of Problem Behavior
- Attention From Others Social Positive
Reinforcement - Attention follows behavior
- Individual approaches attention giver prior to
behavior - Smiling prior to behavior
- Treatment
- Give attention at other times
- Reduce attention to behavior
22Causes of Problem Behavior
- Self Stimulation Internal Sensory Positive
Reinforcement - Continues doing the behavior because it offers a
desired level of stimulation - Behavior continues at steady rate
- Treatment
- Increase sensory stimulation
- Reduce stimulation level of behavior
23Causes of Problem Behavior
- Environmental Consequences External Sensory
Positive Reinforcement - Behavior maintained by reinforcing sights and
sounds from the nonsocial external environment - Behavior continues undiminished even though it
appears to have no social consequences over
numerous occasions - Treatment
- Sensory reinforcement of a desirable alternate
behavior
24Causes of Problem Behavior
- Escape From Demands Social Negative
Reinforcement - Escape from aversive stimuli
- Problem behavior as a way to escape various
undesirable demands - Behavior only happens when certain types of
requests are made of the person - Treatment
- Persist with requests (demands) until compliance
- Teach other responses
- Program where level of difficulty of requested
behavior starts low and is gradually increased
25Causes of Problem Behavior
- Elicited Respondent
- Some behavior is elicited rather than controlled
by consequences - Behavior consistently occurs in a certain
situation or in the presence of certain stimuli - Behavior seems involuntary
- Treatment
- Establishing one or more responses that compete
with problem behavior (counterconditioning)
26Causes of Problem Behavior
- Medical
- Problem emerges suddenly and does not seem to be
related to any changes in the individuals
environment - Behavioral diagnostics
- Therapist diagnoses the problem after examining
antecedents, consequences, and medical and
nutritional variables as potential causes of
problem behaviors - Develop treatment plan based on diagnosis
- Physician should be consulted prior to treatment
27Guidelines for Conducting Functional Assessment
- Define the problem behavior
- Identify antecedents
- Identify consequences
- Consider health/medical/personal variables
- Form hypothesis based on information collected
- Collect data to determine if hypothesis is
correct - If possible, do a functional analysis by directly
testing the hypothesis - Design treatment program
- If treatment is successful, accept the causal
analysis as confirmed. - If treatment is not successful, redo the
functional analysis
28Examples of FBA measures
- FAST
- FBA Inventory
- ABC chart
- See pg. 295 of text
29Chapter 23
- Doing Research in Behavior Modification
30Reversal-Replication (ABAB) Research Designs
- Baseline (A) is followed by treatment (B), return
to baseline (A) condition, and then treatment
again (B) - Allows for replication of treatment effect
- Replication makes it clearer that treatment
caused change in behavior
31Reversal-Replication (ABAB) Research Designs
32Reversal-Replication (ABAB) Research Designs
33Reversal-Replication (ABAB) Research Designs
- Considerations
- Do baseline until pattern is stable and
predictable - May be undesirable to do a reversal (dangerous
behaviors) - May be unable to do a reversal if natural
reinforcers have already taken effect (behavioral
trapping) - How many reversals and replications are
necessary? - Less replications if large effects are observed
and a lot of previous research exists in the area - Limitations
- Withdrawal of treatment may not lead to return to
baseline - Withdrawal may be undesirable or unethical
34Multiple-Baseline Designs
- Conduct more than one AB design concurrently with
treatments beginning at different times - Useful when reversals cannot be introduced
35Multiple-Baseline Designs
- Across behaviors
- Baselining several similar behaviors within an
individual - Across subjects
- Applying the same treatment to the same behavior
problems of two or more individuals - Across situations
- Baselining one type of behavior for a single
individual in more than one setting
36Multiple-Baseline Designs
37Changing-Criterion Designs
- Change over time the criterion for success and
look for relationship between criteria changes
and behavior change - Can increase or decrease
- Frequency requirements
- Rate requirements
- Duration requirements
- Etc.
38Changing-Criterion Designs
39Multiple-Baseline Designs (cont.)
- Compare effects of two or more treatment
conditions considerably more rapidly than in ABAB
design - Applied at alternating times within the same time
period - Also known as multielement design
- Does not require reversal
- Several treatments can be evaluated at the same
time - Disadvantage treatment effects interaction
40Data Analysis and Interpretation
- Data typically analyzed without control groups
and statistical techniques used in other areas of
psychology - Behavior modifiers interested in understanding
and improving the behavior of individuals, not
groups
41Data Analysis and Interpretation
- No control groups or statistics, just visual
inspection of data graphs to draw conclusions. - Number of replications.
- Quantitative difference between baseline and
treatment behavior. - Latency of treatment effects.
- Number of overlaps baseline and treatment.
- Precision of treatment procedures.
- Reliability of response measures.
- Consistency of findings with existing data and
theory. - Practical impact of results.
- Consumer satisfaction.
42Data Analysis and Interpretation
- Social Validity
- Behavior modifiers need to socially validate
their work on at least three levels (Wolf, 1978) - Must examine the extent to which target behaviors
identified for treatment programs are really the
most important for client and society - Must be concerned with the acceptability to the
client of the particular procedures used - Must ensure that the consumers are satisfied with
the results
43Advantages of Within Subjects (Single-case, N of
1) Designs
- Repeated measurements vs. Data at single point in
time - Small number of subjects vs. Large number of
subjects - No resistance to control group participation from
subjects - No need for statistical assumptions of normal
distribution of DV and random selection of
subjects from population
