RELIABILITY AND VALIDITY OF THE FUNCTIONAL ANALYSIS SCREENING TOOL

Iwata, Brian A., DeLeon, Iser G., Roscoe, Eileen M.·2013·Journal of Applied Behavior Analysis

Abstract

The Functional Analysis Screening Tool (FAST) is a 16‐item questionnaire about antecedent and consequent events that might be correlated with the occurrence of problem behavior. Items are organized into 4 functional categories based on contingencies that maintain problem behavior. We assessed interrater reliability of the FAST with 196 problem behaviors through independent administration to pairs of raters (Study 1). Mean item‐by‐item agreement between pairs of raters was 71.5%. Agreement for individual items ranged from 53.3% to 84.5%. Agreement on FAST outcomes, based on comparison of informants' highest totals, was 64.8%. We assessed the validity of the FAST by comparing its outcomes with results of 69 functional analyses (Study 2). The FAST score predicted the condition of the functional analysis in which the highest rate of problem behavior occurred in 44 cases (63.8%). Potential uses of the FAST in the context of a clinical interview, as well as limitations, are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
