Title: Behavioral Assessment: Initial Considerations


1
Chapter 20
  • Behavioral Assessment Initial Considerations

2
Behavior Modification Program Phases
  • Screening/Intake
  • Presenting concerns
  • Agency Policies
  • Crisis screening
  • Diagnosis (insurance)

3
Behavior 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.

4
Indirect Assessment Procedures
  • Interviews with the Client and Significant Others
    (See Table 20-1)
  • Rapport
  • Non-judgmental
  • Confidentiality
  • Set target behaviors

5
Indirect Assessment Procedures (cont.)
  • Questionnaires
  • Life History
  • Survey
  • Rating scales and checklists (CBCL, Conners,
    BASC, etc.)

6
Indirect Assessment Procedures (cont.)
  • Role Playing ( to assess behavior in office).
  • Information from Consulting Professionals.
  • Client Self-Monitoring ( not as good as trained
    observers).

7
Direct Assessment Procedures
  • More accurate but more time consuming and thus
    costly.
  • Covert behaviors not observable.

8
Experimental Assessment Procedures
  • Experimental functional analysis See Chap 22

9
DATA 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.

10
DATA 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).

11
Chapter 21
  • Direct Behavioral assessment What to Record and
    How

12
Characteristics 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)

13
Characteristics 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.

14
How 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.

15
Assessing 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.

16
Assessing 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

17
Chapter 22
  • Functional Assessment of the Causes of Problem
    Behavior

18
What is Functional Analysis?
  • Examination of the relationship between behavior
    and its antecedents and consequences
  • Antecedents
  • eliciting stimuli
  • Consequences
  • Positive or negative reinforcement

19
Types of Assessment
  • Questionnaire
  • Completed by those familiar with client
  • Reliability issues
  • Observation
  • Observe what is going on
  • Form hypotheses about antecedents and
    consequences

20
Types 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

21
Causes 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

22
Causes 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

23
Causes 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

24
Causes 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

25
Causes 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)

26
Causes 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

27
Guidelines 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

28
Examples of FBA measures
  • FAST
  • FBA Inventory
  • ABC chart
  • See pg. 295 of text

29
Chapter 23
  • Doing Research in Behavior Modification

30
Reversal-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

31
Reversal-Replication (ABAB) Research Designs
32
Reversal-Replication (ABAB) Research Designs
33
Reversal-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

34
Multiple-Baseline Designs
  • Conduct more than one AB design concurrently with
    treatments beginning at different times
  • Useful when reversals cannot be introduced

35
Multiple-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

36
Multiple-Baseline Designs
37
Changing-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.

38
Changing-Criterion Designs
39
Multiple-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

40
Data 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

41
Data 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.

42
Data 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

43
Advantages 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
