METHODOLOGICAL INFORMATION


Description of methods used for collection/generation of data: A chart review of patients who received early intensive behavioral intervention from 2015 to 2022. 


Instrument: Sundberg, M. L. (2014). The verbal behavior milestones assessment and placement program: The VB-MAPP (2nd ed.). Concord, CA: AVB Press.


Reliability: Interobserver agreement (IOA) was assessed by having a second rater independently code the data for 49% (n = 59) of cases within this data set. Of the 59 records that were re-coded, 55 (93%) were an exact match. For the remaining four records, point-by-point agreement on the nine VB-MAPP domains averaged 86% (range, 78% to 89%).
