behavioral assessment – measurement of target behavior in behavior modification
ofundamental aspect of behavior modification
oimportant reasons
measuring BEFORE treatment provides info as to whether treatment is necessary
helps you choose the ideal treatment
measuring BEFORE and AFTER allows you to determine whether treatment was
Direct and Indirect Assessment
indirect assessment – involves interviews, questionnaires and rating scales to obtain info on target behavior
from person exhibiting action or from others
direct assessment – observes and records target behavior as it occurs
omore accurate than indirect method
omost research relies on this method
Defining the Target Behavior
first step in developing a behavior recoding plan
oincludes active verbs that describe specific behaviors
oobjective and unambiguous
does not use internal states because they are not observable and subjective
does not use labels because they are ambiguous (subjective)
ointerobserver reliability (IOR) – when two people independently observe the behavior and record
that it occurred

obehaviors sure defined by specific characteristics
The Logistics of Recording
the observer
oidentifying who will observe and record the behavior
target behavior typically observed and recorded by a person other than the one exhibiting
the target behavior
omust be in close proximity or watching via video
osome cases the observer is the one exhibiting the behavior
self-monitoring – client observes and records their own behavior
when and where to record
oobservation period – period of time where observer records target; when target behavior is most
likely to occur
indirect assessment may provide best times to observe target behavior
oobservations can take place in
onatural settings – places in which target behavior typically occurs
most representative sample of target behavior can be obtained
ocontrived settings – structured setting
variables that influence behavior can be controlled and manipulated
oobservations of target behavior can be
structured observation – observer coordinates specific events or activities to occur during
period of observation
unstructured observation – no specific events, activates or instructions during observation
Choosing a Recording Method
continuous recording
ocontinuous recording – client is observed continuously throughout observation period and records
