Introduction
Autism spectrum disorder (ASD) is a heterogeneous
condition that encompasses a group of complex brain
development disorders, including those previously known
as early childhood autism, childhood autism, Kanner’s
autism, high-functioning autism, atypical autism, pervasive
developmental disorder not otherwise specified, childhood
disintegrative disorder, and Asperger’s syndrome.1 The
condition is characterized by impairments in social
interaction and communication, as well as restricted and
repetitive patterns of behavior, activities, and interests,
primarily affecting the neurological development of
children. Additionally, individuals with ASD may present a
variety of comorbidities, including hyperactivity, sleep
disorders, gastrointestinal problems, and epilepsy.2-3
The literature highlights that people with disabilities or
disorders are generally perceived by society as abnormal,
alienated, unrealistic, dangerous, and incapable, often facing
prejudice and social stigma. This perception contributes to
the lack of appropriate care and attention for individuals
with ASD in various areas, suppressing the exercise of free
citizenship, which is guaranteed to all citizens.4
In the Brazilian context, although there are no specific
studies on the prevalence of ASD, it is estimated that this
condition affects approximately two million Brazilians.5 In
the United States, where there has been significant progress
in standardized assessment resources and tools, the
incidence of ASD is estimated to be 1 in every 50 children.6
Thus, the urgency of substantial investments focusing on
various aspects of the lives of this population is evident,
aiming at their inclusion and the guarantee of fair and equal
rights.
In 2008, the United Nations (UN) declared April 2 as World
Autism Awareness Day to raise awareness among society
and policymakers about the disorder, provide information,
and break down prejudices, recognizing the condition and
supporting actions for improving the quality of life of
individuals with ASD.7
One of the areas affected by ASD that draws the attention
of health managers is social interaction. Relationships
established through the internet have exponentially spread
over time, helping to overcome physical barriers and
enabling communication among social actors anywhere in
the world.8 In general, social media can be used to extract
information about patterns of interpersonal interaction and
opinions, proving to be an important tool for assessing
social expressions that occur in various social movements,
such as World Autism Awareness Week.9
Therefore, identifying and understanding the main
expressions on social media regarding the population with
autism is necessary to demystify the topic, thereby allowing
for the dissemination of information aimed at guiding the
actions of competent authorities and assisting in
implementing inclusive public policies nationwide. Thus,
the study aimed to analyze the Brazilian expressions on
Twitter concerning World Autism Awareness Week.
Methods
We conducted a qualitative, descriptive, and document-
based study. We adopted the Discursive Textual Analysis
(DTA) as the methodological framework, an approach that
integrates elements from traditional content analysis and
discourse analysis, characterized as a self-organized process
of construction and understanding, demonstrating an
interpretative movement of a hermeneutic nature.10
Regarding document-based research, studies using this
methodology primarily utilize documents without analytical
treatment, meaning they have not been previously analyzed
or systematized. In discursive textual analysis, both
description and interpretation are elements of analysis, with
these stages occurring concurrently within the article. From
this perspective, interpretation requires a systematic and
argumentative understanding of the information.10
The study setting was the social media platform Twitter,
which provides a publicly accessible global database,
chosen for its importance as a communication tool
between governmental and non-governmental
organizations and the general population. We conducted
data collection from April 3 to April 10, 2023, considering
that April 2 is recognized as World Autism Awareness Day,
established by the United Nations (UN) and instituted in
Brazil by Law 13,652/2018, marking the beginning of
World Autism Awareness Week.
We considered the following inclusion criteria: tweets
published between March 3 and March 10, 2023 (filtered
using the MAXQDA Plus software), in Brazil, in the
Portuguese language (Brazil), and containing the
intersection of the hashtags
#diamundialdeconscientizaçãodoautismo
(#worldautismawarenessday) [Supplementary Material
No.1] and #autistas (#autisticpeople) [Supplementary
Material No. 2 and Supplementary Material No. 3], with no
profile restrictions. Exclusion criteria included publications
that did not represent the research subject. We selected the
hashtags based on an analysis of Twitter’s trending topics,
which are the most frequently mentioned and trending
topics at the time of the research.
We included all tweets made during the data collection
period that met the selection criteria in the study. People
worldwide have been using Twitter to discuss issues of
great societal interest, such as debates and statements from
government organizations, including direct speeches from
heads of state.11 Therefore, we decided to use tweets
published throughout the national territory, originating
from different regions of Brazil.
We considered the number of likes on tweets as
interactions sharing the original post, signifying agreement
with the content and consent for the publications.12 Based
