Reliability

The following data are based on the first 1358 initial (baseline) ATEC forms submitted to the Autism Research Institute. “Initial” refers to the first ATEC form submitted for a given individual.

Since the primary function of the ATEC is to measure the efficacy of interventions, it is expected that a number of ATECs will be submitted for each individual periodically during the trial of the intervention, subsequent to the initial (baseline) ATEC.

Reliability

Pearson split-half (internal consistency) coefficient

N=1358

  Uncorrected r
Scale I Speech .920
Scale II: Sociability .836
Scale III: Sensory/Cognitive Awareness .875
Scale IV: Health/Physical/Behavior .815
Total ATEC Score .942

Score Distributions

The purpose of the ATEC is to measure change in an individual due to various interventions – that is – the difference between the initial (baseline) ATEC scores and later ATEC scores. Nevertheless, we are often asked for normative data, which permit comparison of one individual with others. Here are the score distributions. (The lower the scores, the better.)

A recent study employed the ATEC and MSEC scales to assess autistic children between 2 and 7 years old and found a consistent association between age and symptom severity (https://www.mdpi.com/2227-9067/9/5/701).
