Document Summary

We have to find a way to combine the ratings: Or rule: a given symptom is present if any informant says it is. And rule: a given symptom is present only if all informants say it is. Much more restrictive ; far fewer cases will be identified. These are two totally different approaches; will get a different answer depending on which one you apply. Challenge: both of the and and or rules do not capture the fact that the differences between informants are valuable. Diagnosis by teacher is likely different than one identified by a parent. Parent-reported, teacher-reported, combined (reported by both parents and teachers) Interviews and rating scales rely on someone"s report of behaviour. We may want to observe the behaviour directly: reasons to why. In some cases, it may be difficult for someone without clinical training to tell when a behaviour is normative or clinically concerning. Observation provides access to the circumstances in which behaviour occurs.
