Psychometric Evaluation of Two Adult Autism Screening Tools in Brazil / Louise DO NASCIMENTO MARQUES in Autism Research, 18-9 (September 2025)

Underdiagnosis or misdiagnosis may be particularly prevalent among women who often present subtler social and behavioral characteristics, engage in camouflaging strategies, and exhibit different symptom expressions compared to men. This study evaluates two new instruments to improve screening for ASD among adults in Brazil: the Screening for Autism in Adults (SfA-A) and the Screening for Autism in Females (SfA-F). A sample of 3302 Brazilian adults (mean age=37.55±11.34 years) completed the SfA-A, while 7738 Brazilian adult women (mean age=38.77±10.28 years) completed the SfA-F. Exploratory Structural Equation Modeling was conducted. Reliability was assessed using Cronbach's alpha, McDonald's omega, and test?retest. Criterion validity was determined by the AQ-10 and two autism-related questions. Norms were established based on percentiles. Exploratory and confirmatory factor analyses indicated that the SfA-A and SfA-F exhibited strong model fit, high internal consistency (α=0.8), and initial evidence of criterion-related validity. The SfA-A and SfA-F were developed to address critical gaps in ASD screening among adults in Brazil. These tools hold promise for identifying ASD symptoms and can be used to initiate formal ASD evaluation.

The global burden of conduct disorder and attention-deficit/hyperactivity disorder in 2010 / Holly E. ERSKINE in Journal of Child Psychology and Psychiatry, 55-4 (April 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-4 (April 2014) . - p.328-336 Titre : The global burden of conduct disorder and attention-deficit/hyperactivity disorder in 2010 Type de document : texte imprimé Auteurs : Holly E. ERSKINE, Auteur ; Alize J. FERRARI, Auteur ; Guilherme V. POLANCZYK, Auteur ; Terrie E. MOFFITT, Auteur ; Christopher MURRAY, Auteur ; Theo VOS, Auteur ; Harvey A. WHITEFORD, Auteur ; James G. SCOTT, Auteur Article en page(s) : p.328-336 Mots-clés : Global burden of disease study 2010  conduct disorder  attention-deficit/hyperactivity disorder  disability-adjusted life year  years lived with disability Index. décimale : PER Périodiques Résumé : Objective The Global Burden of Disease Study 2010 (GBD 2010) is the first to include conduct disorder (CD) and attention-deficit/hyperactivity disorder (ADHD) for burden quantification. Method A previous systematic review pooled the available epidemiological data for CD and ADHD, and predicted prevalence by country, region, age and sex for each disorder. Prevalence was then multiplied by a disability weight to calculate years lived with disability (YLDs). As no evidence of deaths resulting directly from either CD or ADHD was found, no years of life lost (YLLs) were calculated. Therefore, the number of disability-adjusted life years (DALYs) was equal to that of YLDs. Results Globally, CD was responsible for 5.75 million YLDs/DALYs with ADHD responsible for a further 491,500. Collectively, CD and ADHD accounted for 0.80% of total global YLDs and 0.25% of total global DALYs. In terms of global DALYs, CD was the 72nd leading contributor and among the 15 leading causes in children aged 5–19 years. Between 1990 and 2010, global DALYs attributable to CD and ADHD remained stable after accounting for population growth and ageing. Conclusions The global burden of CD and ADHD is significant, particularly in male children. Appropriate allocation of resources to address the high morbidity associated with CD and ADHD is necessary to reduce global burden. However, burden estimation was limited by data lacking for all four epidemiological parameters and by methodological challenges in quantifying disability. Future studies need to address these limitations in order to increase the accuracy of burden quantification.
