Methods Participants and Procedures Participants were recruited online, via social media networks, characterizing a
snowball method, in which one participant invites others, by sharing the link with the
invitation. The link opened an online form, consisting of a first page describing the research
and asking participants to give their informed consent by clicking “I understand and accept
the terms above” and confirming they were aged 18 or older before proceeding. Subsequently,
there were a sociodemographic and health questionnaire, to help characterize the sample (sex,
age, region etc.) and enquire about physical and mental health and use of medication,
followed by the instruments’ items.
There were no missing data, since the form required answers to every question.
Overall, 329 people completed the research form, and 262 (63% female) remained after
applying exclusion criteria. A total of 5 participants were excluded from sample because they
reported a confirmed diagnostic of ASD, another 54 participants were excluded because they
claimed to have other neurological / psychiatric conditions, of which the most frequent were
depressive (35 entries) and anxiety (11 entries) disorders. Also, 8 people were excluded
because they claimed to be taking controlled mental health medication, even though they
didn`t report any mental disorders. The final sample represented 21 Brazilian states, more
expressively the southeast (60,3%), and the northeast (20,2%) regions, ranging from 18 to 73
years old (median=31; Q1=26, Q3=38), and from different educational levels and financial
status, as may be observed in Tables 1 and 2.
