Identify functional relations & guide tx
development
Purpose of functional assessment
indirect assessment
Descriptive assessment
Structured descriptive assessment
Functional analysis
4 types of functional assessments
Assessment of bx that is removed from time
& place from actual occurrence of bx
Indirect assessment (IA)
Motivation assessment scale Questions about behavioral function Functional analysis interview form Problem bx questionnaire FAST
5 common forms of indirect assessment
Method of obtaining hypothesis not clear Limited on idiosyncratic variables Reliance on recollection Poor inter-rater agreement Poor convergent validity
5 indirect assessment of limitations
Use as part of direct observation
Include open-ended questions
Use multiple informants
3 recommendations for IA use
Observing individuals in natural environment
by noting events before & after bx
Descriptive assessment (DA)
Narrative recording Open-ended ABC Coded ABC Scatterplot Structured descriptive assessment
5 common forms of descriptive assessment
Correlational nature of data
Reactivity
Sample of bx may be inadequate
Poor convergent validity
4 descriptive assessment limitations
Methodology for arranging environmental
variables to compare levels of bx in test &
control conditions
Functional analysis (FA)
Determines true functional relations
May reveal tx effects
2 of benefits FA
May not include relevant test conditions May not identify situational features occasioning problem bx Potential for iatrogenic effects Complex, time and labor intensive
4 limitations of FA
No clear difference between test & control
conditions
Undifferentiated FA
Multiple control
Automatic SR+
Discrimination issues
Relevant variables not tested
4 possible causes of undifferentiated FAs
Rule out biological/medical events
Limit pre-session access to reinforcers
2 FA best practice techniques before
analysis
