Mean Duration (or IRT)-Per-Occurrence IOA ✔✔Duration IOA B1 + Duration IOA B2 +
Duration IOA Bn/n Behaviors with Duration IOA
Interval-By-Interval IOA ✔✔# of Intervals Both Recorders Agree/Total # of Intervals x 100%
Scored Interval IOA ✔✔# of Intervals Both Recorders Recorded Occurrence/# of Intervals AT
LEAST ONE Recorder Recorded Occurrence x 100%
Unscored Interval IOA ✔✔# of Intervals Both Recorders Recorded Non-Occurrence/# of
Intervals AT LEAST ONE Recorder Recorded Non-Occurrence x 100%
For Increasing Behaviors ✔✔Baseline Average < Initial Criterion = Highest Performance in
Baseline
For Decreasing Behaviors ✔✔Baseline Average > Initial Criterion >/= Lowest Performance in
Baseline
Setting Initial NCR Schedule ✔✔Total Duration of All Baseline Sessions/Total # of Behaviors
Recorded During Baseline Sessions
Setting Initial DRO Interval ✔✔Total Duration of All Baseline Sessions/Total # of Behaviors
Recorded During Baseline Sessions
Full Session DRL ✔✔Total # of Behaviors Recorded During Baseline Sessions/Total # of Each
Baseline Session
Interval & Spaced Responding DRL ✔✔Total Duration of Baseline Sessions/Baseline Average
of Behaviors per Baseline Sessions = # of Behaviors per duration
Conditional Probabilities ✔✔# of Behaviors Preceded by a Specific Antecedent &/or Followed
by a Specific Consequence/Total # of Behaviors - always reported in decimal form
