The Goals of Modules 11 and 12 are to:
Review the dimentional properties of behavior (the distinct features that can be measured)
Instructor:

Dr. Michael Cameron

Registered Behavior Technician Modules:

A-01 and A-02 (Measurement)
Title:

Prepare for Data Collection and Implement Continuous Measurement Procedures
Duration:

60 Minutes

Assessment:

Competency based quiz (5 questions)
Demonstration Requirements:

At the conclusion of this training,
Ask
your BCBA supervisor to review the data collection systems he or she uses (e.g., hard copy or iPad enabled or tablet enabled) systems,
Rehearse
the data collection process by using the prescribed system and by watching a video session of someone working with a client or student (preferably, the same person you will be working with), and
Demonstate
your ability to collect data in vivo.
Module
Goals

Provide you with specific recommnedations for
preparing for your data collection responsibilities
Review the rationale for measurement
Describe the difference between "continuous" and
"discontinuous" data collection procedures
Provide a detailed overview of the continuous data collection
procedures you will use as a Registered Behavior Technician
Start with
Why
To evaluate baseline performance and effects of intervention (programs based on assessments)
To guide decision making

To prevent mistakes (continuing ineffective treatment or discontinuing effective treatment)
To verifiy the legitamacy of treatment
For Accountability (the stakeholders)

What we Need

generates accurate data
produces reliable information
sensitive to changes in the
occurrence of behavior
Quality Data Collecion
Continuous

Those that capture every possible behavioral
occurrence either by recording each instance of a
behavior (e.g., frequency) or by recording the
number of seconds each instance of behavior occurs
(e.g., duration)
This form of data collecton offers a
complete record that can be expressed
in standard scientiifc units (e.g.,
responses per minute)
What we can Measure
The Measurable Dimensions
Repeatability or countability
(behavior can be counted)
Temporal extent (duration)

Temporal locus
(when behavior occurs)
Discontinuous

Those that capture only a sample
of behavior during an observation

Continuous Data Collection
Options
Description:
Example:
Reality A
frequency
measure should only be used if the length of the observation time is consistent from one observation to the next (e..g, a 10 minute time interval for recording the number of words a child reads). A
rate
measure should be used
(e.g., number of words read per minute) when an observation time varies.
How to Collect:
Specifics of Data Collection
Frequency and Rate.
These methods involve counting the number of occurrences of a behavior within a specific time frame. Only use this method when a behavor has a clear beginning and end point (
repeatability
).
Throwing a baseball, leaving your seat, a child raising their hand in class.
Quick Review
You have committed to impacting a
person's quality of life
All assessments have been completed
Programs have been developed
You are measuring to verify progress
Cultural Fit and Aesthetics
Description: The
duration
measure requires you to document the length (
extent
) of a behavior by recording the time a behavior begins and ends. This is not a measure you will use if a behavior occurs frequently and has a rapid "start and stop" cycle.
Example: The length of time spent playing the piano. The amount of time spent completing problems on a math worksheet.
Reality When the duration measure is the appropriate method for collecting data, the measure provides information about the temporal extent of a behavior and the frequnecy of behavioral episodes.
How to Collect the Data:
Description: Use
latency
recording when you are interested in measuring how long it takes someone to begin performing a target behavior once an opportunity is presented (
locus
).
Example:
Receiving a parking ticket and paying it. The time between delivering an
instucton and a person following the instruction.
Reality
Latency and duration both measure time; however,
latency is a measure of long it takes for a behavior to start and duration is a meausre of how long the behavior
lasts
.
How to Collect Data:
Description:
Interresponse time (IRT)
is the amount of time that elapses between two consecutive instances of a response (
locus
).
Example: 5 minutes elapsed between two instances of screaming.
3 seconds elapsed between eating the 1st and 2nd potato chip
Reality
IRT is another time measure, but concerned
with the time distance between responses
How to Collect Data:
Questions
Answers
True or False. Continuous data provides you
with a "sample" of behavior.
False. Continuous data captres every
possible occurrence.
True or False. The three measurable dimensions of
behavior are: 1) repeatability, 2) temporal extent, and
3) temporal locus
True
Provide one important reason for
collecting data
Data guides decision making
Which data collection should be used if you want
to measure the length of time a behavior occurs?
Duration
Which data collection systems should be avoided if
a behavior does not have a clear beginning of clear end?
Frequency and rate
Watch for
"reactivity"
