Abstract

Background:

Early identification of Autism Spectrum Disorder (ASD) is of paramount importance in establishing effective interventions. Currently, the accepted gold standard for ASD diagnosis is the Autism Diagnostic Observation Schedule, 2nd Edition (ADOS-2).

Methods:

In our research study, we applied a novel approach to the ADOS-2 known as the Formal Psychological Assessment (FPA). The innovation of this methodology comes from the construction of a matrix that allows (1) the identification of the existing relations among items in terms of clinical symptoms and (2) an adaptive assessment of an individual.

Objective:

The aim of this study was to use a practical application of the FPA on the ADOS-2 and show its potential for psychological assessment of individuals with ASD. Particularly, this research raises some important considerations regarding the evaluation of this population and the authors propose future work to improve the quality of clinical assessment.

Results:

Our results suggest potential for the application of this new methodology to the ADOS-2 to support clinicians using diagnostic procedures.

Conclusion:

The use of FPA allows analysis of each item of ADOS’s modules based on the presence/absence of clinical elements. This system allows the identification of the critical areas for each individual and reduces the number of items required for the test.

Keywords: Autism Spectrum Disorder (ASD), Autism Diagnostic Observation Schedule, Second Edition (ADOS-2), Diagnosis, Formal Psychological Assessment (FPA), Adaptive testing system, Methodology.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."
