Behavior Modification: Principles & Procedures
Chapter 13 Understanding Problem Behaviors through Functional Assessment
When using behavioral modification procedures to help a person increase a
desirable behavior or decrease or eliminate an undesirable behavior you
must conduct an assessment of the three-term contingency to determine the
antecedent events that evoke the behavior and the reinforcing consequences
that maintain it the process of identifying these variables before treating a
problem behavior is called functional assessment
Conducting a functional assessment is always the first step in using behavior
modification procedures to decrease problem behaviors
One basic principle of behavior analysis is that behavior is lawful
regardless of whether to the behavior is desirable or not, its occurrence is
controlled by environmental variables (it is a function of the environment)
Respondent behavior is controlled by antecedent stimuli, and operant
behavior is controlled by antecedents and consequences that make up three-
terms contingencies of reinforcement and punishment
Functional assessment is the process of gathering information about the
antecedents and consequences that are functionally related to the occurrence
of a problem behavior it provides information that helps you determine
why a problem behavior is occurring
Four broad classes of reinforcing consequences or functions of problem
behaviors:
o Social positive reinforcement: a positive reinforcing consequence is
delivered by another person after the target behavior (ex. Attention)
o Social negative reinforcement: another person terminates an aversive
interaction, task or activity after the occurrence of a target behavior,
and as a result, the behavior is most likely to occur (ex. Complaining)
o Automatic positive reinforcement: behavior produced a reinforcing
consequence automatically & behavior is strengthened
o Automatic negative reinforcement: escape from the aversive stimulus
is not mediated by the actions of another person (ex. Binge eating)
Three categories to conduct functional assessments:
o Indirect assessment methods (informant assessment): information
gathered through interviews and questionnaires
o Direct observation (ABC observation): observer records the subject
3 ways: descriptive method (observer writes a brief
description of the behavior, antecedent and consequences),
checklist method (typically made after ABC’s are identified)
and interval (or real time) recording method (divide
observation period into brief time intervals and record
whether behavior occurred in each interval & exact time)
o Experimental methods (experimental analysis or functional analysis):
antecedents and consequences are manipulated to observe effect on
problem behavior

Chapter 13 understanding problem behaviors through functional assessment. Conducting a functional assessment is always the first step in using behavior modification procedures to decrease problem behaviors. One basic principle of behavior analysis is that behavior is lawful regardless of whether to the behavior is desirable or not, its occurrence is controlled by environmental variables (it is a function of the environment) Respondent behavior is controlled by antecedent stimuli, and operant behavior is controlled by antecedents and consequences that make up three- terms contingencies of reinforcement and punishment. Functional assessment is the process of gathering information about the antecedents and consequences that are functionally related to the occurrence of a problem behavior it provides information that helps you determine why a problem behavior is occurring.
