Preference Assessment
*Methods for identifying items and activities that MAY function as reinforcers
- 3 general approaches:
- Ask (Indirect)
- Watch (Naturalistic Observations)
- Test (Direct)
Indirect
- Informant Based:
- Can be client directly or parent/ caregiver/ teacher
- Interviews; Forms
- Used in inform later assessments
Naturalistic Observation
- Decide the most relevant “free time” to observe
- Record duration of interactions
- Direct observations
Advantages of Naturalistic Observations
- Does not require verbal response
- Does not require removal
- Does not require “trials”
- Relevant setting
- Can observe the manner in which they play
Direct preference assessments
- Arranging items or activities to observe client selection and engagement
- Data to collect:
- Percent of selection
- Duration of engagement
- Trial-Based
- 1 or More items presented across trials & approach is measured
- Single-Stimulus (Pace 85)
- Paired-Stimulus (Fisher 92)
- Multiple-Stimulus (Windsor, DeLeon & Iwata)
*Single-Stimulus-Procedures
Identify items and set up Present one at a time Wait for approach (If no approach: remove) Record data Start next trial
Single-Stimulus- Advantages and Disadvantages
- Can identify many items
- Prone to fasle positives
- Don’t know the relative value
Paired-Stimulus
- Items presented in pairs
- All possible combinations
- Time consuming
- Results in a hierarchy
Paired- Stimulus Procedures
- Present 2 items
- Wait for approach; allow access; remove other
- No approach: remove and represent
- Reach for both: Block
- Record data
- Next trial
*Position Bias
-Continuing to select items on a particular side regardless of items present
*Multiple Stimulus
- Present all items simultaneously
- Participant selects one
- More time efficient
- Can return a hierarchy
*MSW - Procedure
- Present all items
- Give instruction to “choose”; remove unselected items; block attempts to grab at others
- Record data
- Re-present ALL items
*MSWO- Procedure
- Present all items
- Give instruction to “choose”; remove unselected items; block attempts to grab at others
- Record data
- Re-present remaining items
MS Limitations
- Only useful with table-top items
- Stimuli are taken away
- No hierarchy: MSW
- MSWO provides a hierarchy (advantage)
Variations
- Sometimes items or activities cannot be made readily available to display
- 2 common alternatives:
- Vocal
- Pictorial
Vocal
- Options presented vocally
- Client selects from named items/activities
- Prerequisite:
- Sufficient verbal behavior
Pictorial
*Provide pictures for each activity and participant can select from options
- Prerequisite:
- Picture-to-object matching
Duration-Based
*Rather than measuring selection, you measure the amount of time spent with items or activities
- 2 common formats:
- Free operant
- Single-item
Free Operant - Procedures
- Present all items (doesn’t have to be at the table)
- Allow access for entire assessment time
- Record duration with each item
- Rank based on engagement
Single-item Duration
-Present item, start timer
-Allow up to 2 minutes of access
‘Start a 2nd timer:
When individual starts to interact
(Stop 2nd timer when they stop)
-After 2 minutes, stop timer(s) and remove items
-Record data

Preference Assessment:
Methods for identifying an individual’s preference for items and/or activities that may function as reinforcers in actual training/ treatment
•Conducted under low effort requirements with simplistic responses
–i.e.SPA do NOT guarantee utility of a stimulus as a R+ in actual training/Tx
–Stimulus Preference Assessment and Reinforcer assessment are NOT the same thing!
3 Methods to Identify Preferences
- Indirect-informant based (ASK)
- Naturalistic-“in-vivo”direct observation of behavior in the environment (WATCH)
- Reinforcer sampling (OFFER)
Indirect Preference Assessment
- Informant-based assessment that provides information about an individual’s preference for tangible items and/or activities
- Ask client or CG what items the client prefers
- Use scale, survey, inventory checklist
Indirect Preference Assessment
- Advantages: Easy & Quick to complete
- Disadvantages: May identify multiple items/ activities as high preference
- Not necessarily accurate
-Naturalistic Observation
- Direct assessment
- Collecting data in the natural env to find high probability bxs
-Naturalistic Observation
- Advantage:
- R+ not withdrawn & therapist not presenting demand “choose one” so might decrease likelihood of prob bx
- Disadvantages:
- Time consuming, Potential limited access to stimuli, May only engage with a few items

Structured Preference Assessment Methods
- Direct: Observation-based assessment that provides information about an individual’s preference for tangible items and/or activities
- Trial/selection-based
- Duration based
Trial-based Preference Assessment
•Direct preference assessment in which one or more items is/are presented across trials and approach is measured
Trial-Based Preference Assessment
•Single Stimulus •Paired-choice •Multiple stimulus –With replacement –Without replacement
Single-Stimulus Preference Assessment
•Place items, one at a time in front of the person
–Typically, 10 trials per item
•Measure whether they approach the item
•Hierarchy based on the number of times an item was approached given the number of times it was available:
–Approaches/trials
Single-Stimulus Preference Assessment
-Advantages
–Good for individuals with severe deficits
–Does not require scanning an array, making a choice
–May assess larger numbers of stimuli
Single-Stimulus Assessment
•Disadvantages
–Difficult to identify info about relative preferences
–Undifferentiated approach may produce false positives
•Select anything in front of them, items may not actually function as reinforcers later
The following problem(s) are associated with the single stimulus method
A .indiscriminate responses B. potential for false positives C. potential for false negatives D. A and B E.A and C
D. A and B
Adele is conducting a single-stimulus preference assessment. She places an action figure in front of her client, and they pick it up and look at it. What should Adele do next?
A .Place the next toy on the table
B. Take the action figure back from the client
C. record the engagement with the item
D. wait for the child to stop playing with the toy
C. record the engagement with the item
Paired-Stimulus Assessment
- Paired (forced) choice
- Place items, two at a time in front of the person
- Trials continue until each item has been paired with each other item once (all possible pair-wise permutations)
- Number of trials = n (n-1) / 2 •Record which item they approached each trial
Paired-Stimulus Assessment
Cont…d
-Hierarchy based on the number of times an item was approached given the number of times it was available:
•Approaches/trials
Paired-Stimulus Assessment
Advantages
–Greatest differentiation among stimuli
–Most accurate
–provides preference hierarchy
Paired-Stimulus Assessment
Disadvantage
–Very time consuming
–Potential for side/position bias
•Item chosen due to position
Paired-stimulus Formats
•Ta n g i b l e-Present actual item
•Vocal-No item presented, just ask•
Pictorial-present picture of activity
Adele is conducting a paired-stimulus preference assessment. She places a doll and a small dragon in front of her client, and the client picks up the dragon. The next time Adele presents the dragon it should be:
A. in the same position and presented with the doll
B. in the other position and presented with the doll
C. in the same position and presented with a different toy
D. in the other position and presented with a different toy
D. in the other position and presented with a different toy
Multiple Stimulus Assessment
•Least time consuming
•Array of stimuli presented simultaneously & approach measured
•May still be limited in the # of stimuli that can be assessed•
2 Variations
–With item replacement (MSW)
–Without item replacement (MSWO)
Multiple Stimulus With Replacement
•Selected items are returned to the array after each presentation
•Provides info on the most preferred stimulus or stimuli
–False Negative
Multiple Stimulus Without Replacement
•Selected items removed from and not returned to the array
•provides more information about preferences among the array
•May see “save the best for last” phenomenon
–Reverse hierarchy

Duration-Based Preference Assessment
•When trial-based methods do not yield differentiated results, looking at the amount/ proportion of time spent engaging with the item may help determine relative preferences.
•Two types:
–Free Operant
–Single Item Duration
Free Operant Preference Assessment
- Present specific items simultaneously, and measure duration (or partial interval) of engagement with each item
- Differs slightly from naturalistic observation, in that we provide items
Free Operant Preference Assessment
Advantages

–Less likelihood of problem behavior evoked by denied access/removal–
No position bias
Free Operant Preference Assessment
Disadvantages
–Prone to false negatives
–May not produce a preference hierarchy
Single-Item Duration Preference Assessment
Present one item at a time, measure duration of engagement
*Advantages–May help clarify results if selection-based approaches result in semi-equal selection across items
•Disadvantage–May be more time consuming than other methods

Considerations in Selecting Preference Assessments
•Individual’s abilities
–Scanning an array, physical limitations that may lead to position bias
–Visual discriminations, match to sample, auditory match to sample, verbal •Indirect/Informant based–Low quality–Efficient–Good start: generate a list of items to test
*Problem Bx
*Time availability/ Efficiency of methods
*Quality/ Predictive accuracy
Considerations in Selecting Preference Assessments
•Indirect/Informant based
–Low quality
–Efficient
–Good start: generate a list of items to test
Considerations in Selecting Preference Assessments
•Naturalistic observation
–Identifies high preference items, prone to false negatives
–Time consuming
–Not likely to evoke prob bx maintained by access to tangibles (no denied access/removal)
–May evoke attention-seeking bx
Considerations in Selecting Preference Assessments
•Single Stimulus
–Prone to false positives: individuals just engage with everything
–Efficient–
Able to assess larger numbers of items
–Good for individuals who cannot scan an array
–Denied access/removal may evoke problem behavior
Considerations in Selecting Preference Assessments
*Paired Choice
–Most accurate hierarchy
–Time consuming
–Can be subject to position bias
–Requires ability to scan an array match to sample, or auditory match to sample if using complex stimuli (pictorial or verbal)
–Denied access/removal may evoke problem behavior
Considerations in Selecting Preference Assessments
•MSW
–Yields high preference items, prone to false negatives
–Efficient
–Requires ability to scan an array, make a choice
–Denied access/removal may evoke problem behavior
Considerations in Selecting Preference Assessments
•MSWO
–Yields relative preference hierarchy
–Efficient: great for daily use
–Requires ability to scan an array, make a choice
–Denied access/removal may evoke problem behavior
Considerations in Selecting Preference Assessments
*Free Operant
–Yields high preference items, prone to false negatives
–Efficient
–Does not requires ability to scan an array
–Not likely to evoke problem behavior maintained by tangibles (No denied access/removal)
–May evoke attention-seeking behavior
Direct Preference Assessments
Naturalistic Observation
*Measure engagement with items/activities in their natural environment
Direct Preference Assessments
- Trial-based Methods
- Measure approach/contact/ engagement of presented items
- Duration-based Methods
- Measure proportion of time spent engaged with presented items
