They create a free test to screen for autism spectrum disorders

Autism spectrum disorders represent one of the main types of developmental disorders in children, However, its diagnostic criteria are complex, and diagnosis can be significantly complicated in less obvious cases.

A reliable test

To address these difficulties, a number of researchers are working on what they have named the Autism Symptom Dimension Questionnaire (ASDQ): a free trial Which should serve as a screening tool for this type of disorder. Now, these authors have validated its operation in a cohort of 1,467 children and adolescents, as published in specialized media. Developmental medicine and child neurology.

In this exercise, test proved reliable To assess symptoms of autism without interference from factors such as age, gender, race or ethnicity.

The idea is that the ASDQ could become an alternative psychometric measurement unit for people who are pre-screened for autism spectrum disorders, cover their limitsBased on the criteria established in the DSM-5 (the manual edited by the American Psychiatric Association and currently, one of the main diagnostic references in mental health).

A potential screening tool

To develop the questionnaire, the researchers relied on models of disorders such as estimated a priori Based on nine specific factors: basic social communication, affiliation, perspective taking, peer relationships, repetitive motor behaviors, sensory interests, sensory interests, emphasis on uniformity, sensory sensitivity, and restricted interests.

focus proved successful, since the test showed high reliability in many different demographic levels to detect the risk of suffering from the disorder based on prognostic factors (keeping in mind that the diagnosis would have to be made by a professional). This makes the questionnaire a potential tool for screening for risk for autism spectrum disorder, although the tool needs to be validated in even larger groups before it can achieve potential clinical use.
