I’m a fan of the ATEC. Not only because it was one of the first instruments specifically devised to look at measuring changes to autistic symptom. The Autism Treatment Evaluation Checklist (ATEC) was designed nearly two decades ago to provide such a tool, but the norms on the. The Autism Treatment Evaluation Checklist (ATEC) is a great tool for clinicians and parents to evaluate treatments based on autistic symptoms. ATEC scores.

By introducing the Autism Treatment Evaluation Checklist, the Autism Research Institute is paving the way for pertinent new research information that has heretofor been unavailable or difficult to evaluate. We wish to thank Petr Ilyinskii for productive discussion and scrupulous editing of this manuscript.

As the authors point out: As neurotypical children develop faster, the presence of neurotypical children in the dataset would have artificially increased the magnitude of annual changes of ATEC scores, predominantly for younger participants with mild ASD.

One such possible purpose is diagnosis. Mathematically, the decrease of the ATEC total score is best described by an exponent with a time constant of 3. This paper reports the norms for the longitudinal changes of ATEC scores amongst participants from various countries undergoing a variety of treatments and seeks to develop an outline for tracking developmental changes in individuals with ASD.

For example, in the 2 to 3 age-pair norms calculation, a participant must have completed their first evaluation anytime between the ages 1. Initially, ATEC evaluations were distributed as hard copy. Views Read Edit View history. ATEC can be accessed online or in hard-copy format.

The Autism Treatment Evaluation Checklist (ATEC): Autism Treatment Research Studies:

Because of the large database, researchers and practitioners of specific treatment focuses will also be able to evaluate the effectiveness of their programs, not only in general, but also with specific populations or sub-groups. Newer Post Older Post Home.


Further studies with larger number of participants should be able to shorten the age group definition from whole-year to six months and possibly even three wutism. This manuscript attempts to characterize the typical changes in ATEC score over time as a function of children initial age and ASD severity in a large and diverse group of participants. The fact that they’re based on the reports of over 27, parents also helps matters too For multiple autlsm, it is unlikely that there were many neurotypical participants in the database utilized for this paper.

Autis Catherine Lord, in the Handbook of Autism and Pervasive Developmental Disordershas said, “Often, investigators have to use diagnostic instruments to measure changes in response to treatment.

For example, it is possible that a parent s administered the checklist at 2. Journal of intellectual disability research: High quality practice parameters have now been established to help guide the assessment and treatment of ASD. When used in conjunction with other diagnostic instruments and methods, the ABC may have some usefulness as a symptom inventory to be completed by parents or teachers.

Lacking such a scale, researchers have resorted to using scales such as: A separate booklet, Instructional Objectives for Children Who Have Autismis included in the test kit to assist in the formulation of instructional goals and objectives based autiwm GARS-2 results.

Participants must have filled out at least three autims and the interval between the first and the last evaluation was one year or longer.

Furthermore, none of these tools have published developmental norms [ 15 ]. The ATEC is currently available in 17 different languages. Measuring developmental progress of children with autism spectrum disorder on school qutism using parent report. GARS-2 has been improved in the following ways: The change in the score from the age of 3 years to the age of 4 years in participants with the average score of 48 at the age of 3 years, however, is unknown.


As noted previously by other groups [ 108 ], the use of ATEC as a primary outcome measure has some inherent drawbacks.

Please see Statistical Analyses: A common hurdle in these efforts is the availability of trained technicians needed to conduct rigorous and consistent assessment of children at multiple time points [ 12 ].

The ABC appears to have limited usefulness in identifying children with autism who are under the age of 3. The test consists of 4 subtests: When a single parent completes the same evaluation every three months over multiple years, changes in the score become meaningful.

Stereotyped Behaviors Communication Social Interaction Using objective, frequency-based ratings, the entire scale can be completed and scored in 5 to 10 minutes.

In this way, instruction can be directly related to assessment results from GARS The instrument consists of 42 clearly stated items describing the characteristic behaviors of persons with autism. For example, participants with an initial ATEC total score of 64 at the age of 2 years had on average reduced their score to 48 by the age of 3 years Figure 1vertical arrow. It’s perhaps no coincidence that the ARI also holds some important data on parent ratings of how useful certain interventions were reported to be when it comes to autism see here.

There were other methodological ‘issues’ too that need to be kept in mind.

The internal consistency reliability was high.
