Behavioral assessment - measurement of the target behavior(s) in behavior modification
behavior assessment is important because
oIt provides info on if treatment is necessary
oCan help choose the best treatment
oMeasurement before and after treatment allows you to determine whether the behavior changed after the
treatment was implemented
2 types of behavior assessment:
1.Indirect involves using interviews, questionnaires, and rating scales to obtain info on target behavior from the
person exhibiting the behavior/from others
2.Direct a person observes + records target behavior as it occurs
Steps needed to develop a behavior-recording plan:
1.Defining the target behavior you must identify what the person says/does that constitutes the behavioral
XS/deficit targeted for change
Interobserver reliability (IOR): 2 people independently observe the same behavior and both record
that the behavior occurred
2.Determining the logistics of recording
Self-monitoring: when client observes + recordes their own behavior
Observation period: the specific period where the observer records the target behavior
Natural setting: consists of places in which target behavior typically occurs. Opposite: contrived
setting
Structured: observer arranges for specific events/activities to occur during observation period
Unstructured: no specific events/activities/instructions are given during observation period
3.Choosing a recording method
Continuous: records every instance of behavior occurring during observation period
i.Frequency rate (frequency/time)
ii.Duration (duration/time)
iii.Real-time recording exact time of onset/offset of target behavior is recorded
iv.Intensity
v.Latency the time from some stimulus event to the onset of behavior
vi.Baseline: period during which target behavior is recorded before treatment is implemented
Product (permanent product recording): record tangible outcome/permanent product of the
occurrence of behavior
Interval: record occurrence/nonoccurrence of behavior in consecutive intervals of time during
observation period
i.Partial: simply record whether behavior occurred during each interval time
ii.Whole: occurrence of behavior is marked in an interval only when behavior occurs
throughout entire interval
iii.Frequency-within-interval recording: observer records frequency of target behavior but
does so within consecutive intervals of time in the observation period; this shows you the
frequency of the behavior and the specific intervals in which the behavior occurred
Time sample: record occurrence/nonoccurrence of behavior in discontinuous intervals of time (time
samples) during observation period
4.Choosing a recording instrument what the observer uses to register occurrence of behavior
Reactivity - process of recording a behavior causes behavior to change, even before any treatment is implemented

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.
