How to Analyze IOA by Observer Pair
Analyze IOA by observer pair with pair-specific counts, matched methods and conditions, adequate denominators, disagreement types, and careful follow-up.
Clinician guide
How to Handle Partially Observed Sessions in IOA
Handle partial IOA sessions by limiting calculations to shared valid exposure, retaining unmatched minutes and missing scores, and reporting coverage separately.
Clinician guide
How to Match Events Across Observers for IOA
Match events across observers with prospective identity, order, time-tolerance, context, and boundary rules while retaining unmatched and ambiguous events.
Clinician guide
How to Align Observation Start and Stop Rules for IOA
Align IOA observation windows with synchronized clocks, shared start and stop events, pause rules, late-arrival handling, and a visible exposure denominator.
Clinician guide
How to Reduce Observer Reactivity During IOA
Reduce observer reactivity during IOA by sampling routines, standardizing observer behavior, protecting access, recording visibility, and bounding conclusions.
Clinician guide
How to Preserve Observer Independence During IOA
Preserve observer independence during IOA with separate records, blocked score sharing, predefined safety exceptions, locked timestamps, and documented departures.
Clinician guide
How to Report IOA Results Without Overclaiming
Report the definition, sample, observer independence, calculation, raw agreements, disagreements, prevalence, missingness, range, context, and IOA limits.
Clinician guide
How to Choose an IOA Calculation for ABA Data
Select an IOA method from the measurement dimension, unit, event prevalence, matching feasibility, risk of false reassurance, and clinical decision.
Clinician guide
How to Calculate Duration-per-Occurrence IOA
Match the same events, calculate smaller divided by larger duration for each, average event agreements, and investigate unmatched or partly observed events.
Clinician guide
How to Calculate Unscored-Interval IOA
Divide intervals both observers scored nonoccurrence by intervals either scored nonoccurrence, report prevalence, and use unscored-interval IOA with clear limits.
Clinician guide
How to Calculate Scored-Interval IOA
Divide intervals both observers scored occurrence by intervals either scored occurrence, report prevalence, and use scored-interval IOA with clear limits.
