IOA Must be reported in %
True
When an observer's data collection is influenced by the awareness that they are being monitored and evaluated
Observer Reactivity
Interval Recording
Time Sampling Procedures
This method overestimates the extent of the actual agreement
Total Count IOA
Smaller#/Larger # * 100
OR TOtal Duration IOA
VAR
Validity, accuracy, reliability - 3 indicators of trustworthy measurement (low to high)
IOA should be taken for a minimum of 40% of sessions during each phase of a study, across days of the week, times of day, settings, or observers
FALSE - 20%, AND observers
When observers have a shift in how they interpret the operational definitions of the target behavior
Observer Drift
PLACHECK
This method is the strictest method to collect IOA
Exact count-per-interval IOA
3 threats to validity
Indirect measures, measuring the wrong dimension of the target behavior, measurement artifacts
IOA can be reported in narrative format
TRUE: most common and easiest; report the mean and range of agreement %
Interval-by-interval, Scored interval, un-scored interval
Time Sampling Procedure IOAs
Discontinuous Measurement Systems
Time Sampling Procedures
This method should be used for DTT
Trial-by-trial IOA
# of trials in agreement / total trials * 100
Data do not provide a meaningful representation of the behavior due to unwarranted and misleading picture of behavior because of how it was measured
Measurement Artifacts
IOA goal is 100%
True; at least 80%
Total Duration IOA & Mean Duration-per-occurrence IOA
Temporal Duration IOAs
Point-by-point IOA
Interval-by-Interval IOA
Scored Interval IOA should be used for behaviors that occur at frequencies of approximately _____%
30%; un-scored interval for 70% or more
4 Repeatability Measures
Total Count IOA, Mean count per interval IOA, Exact count per interval IOA, Trial by Trial IOA
FALSE; 8 ways
Total Count IOA, Mean Count-per-interval, exact count-per interval, trial-by-trial IOA
Repeatability Measure IOAs
Point-by-point Agreement Ratio IOA
Interval-by-Interval IOA
Most common means to ensure the quality of measurement in ABA
Interobserver Agreement (IOA)
Temporal Measure IOAs
Total duration IOA, Mean duration per occurrence IOA
