Characteristics of a good response definition
Directly measure a dimensional quantity of behavior (direct)
Continuous response measures
Do not measure behavior directly (indirect)
Discontinuous response measures
Event
Latency
Duration
IRT
Dimensional quantities of continuous response measures
Record time observation began Count the responses Record time observation ended Divide: Count/unit of time Report as rate per unit of time
Event recording
Record time observation began Record each antecedent Record each response Record time observation ended Report as (Responses/Antecedents)/unit of time
Event recording of restricted operants
Total amount of time in individual engages in an activity
Duration per session
Amount of time a target behavior occupies
Duration per occurrence
The number of consecutive opportunities to respond required to achieve a performance standard. Record each opportunity to respond until the performance standard is met.
Trials to criterion
- Determine what one trial will be
- Decide how to report (number of trials or number of block trials)
- Record count as the measure
- Present data
Trials to criterion steps
A method for classifying responses into discrete categories
Discrete categorization
A discontinuous response measure in which a recording session is broken into short intervals of time; occurrence is recorded if a response happens during any part of the interval.
Partial interval recording
A discontinuous response measure in which a recording session is broken into short intervals of time; occurrence is recorded if the behavior occurs for the whole interval.
Whole interval recording
A discontinuous response measure in which a response is recorded as occurring only if it occurs at the point in time in which the interval ends.
Momentary time sampling
A group of individuals is observed at the end of an interval.
Count how many of the individuals are engaging in the target behavior(s). Compare with the total number of individuals. Percent of individuals engaging in behavior(s).
PLACHECK
The dimensional quantity of interest. The estimated rate of the behavior. Whether to measure responses or episodes.
Factors to consider when selecting response measure
Measuring the results of behavior
Permanent products
The consistency of measurement
Reliability
The coefficient of agreement between two or more independent observers. Usually calculated as a percentage by dividing the number of agreements by the total number of agreements plus disagreements, then multiplying by 100.
Interobserver agreement
Competence of new observers
Detecting observer drift
Validate collection methods
Increase confidence that interventions are responsible for behavior change
Uses for IOA
The degree to which an intervention is implemented as described/designated
IV integrity
Total count
Percent agreement
The two main methods of IOA
Total agreement in each interval divided by number of intervals x100
Mean count per interval
of intervals with 100% agreement divided by Number of intervals x 100
Exact count per interval
IOA should be at or above
80%
IOA should be collected and scored for a minimum of _____ of observations
33%
