Evaluating Outcomes Of Measurement Flashcards
To calculate inter observer agreement on duration measures
Divide the time recorded by the observer who recorded the shortest duration by the time recorded by the observer who recorded the longest duration x100
Nonoccurence agreement should be reported when
There is a high response rate
Nonoccurence (un scored interval) IOA considers
Only the intervals in which one or both observers recorded a Nonoccurence. Divide the number of agreements by the number of intervals in which one or both observers recorded a Nonoccurence
To calculate interval-by-interval IOA
Divide the number of intervals in which both observers recorded an agreement by the total number of intervals x100
Occurrence IOA considers
Only intervals in which one or both observers recorded an occurrence. Divide the number of agreements by the number of intervals in which one or both observers recorded an occurrence
