Revisão sistemática da literatura sobre o treinamento para a aplicação do ensino por tentativas discretas
BST keeps winning for DTT training, but newer shortcuts let you finish faster.
01Research in Context
What this study did
Souza’s team hunted for every 2021-2023 paper that used BST to teach DTT.
They found 15 studies. Most trained parents or aides in Brazil.
Telehealth, video models, and checklists were common add-ons.
What they found
Every study hit 80-100 % fidelity after BST.
Remote coaching worked as well as in-person.
No package was clearly faster or cheaper.
How this fits with other research
Briggs et al. (2024) looked at the same question and found 51 studies.
Their bigger map shows trainers now skip rehearsal or cut feedback to save time.
Souza’s 2023 review is still useful, but Briggs gives fresher options.
Matos et al. (2021) is one of the 15 Souza counted; six college students hit 100 % accuracy after one BST afternoon.
Why it matters
BST is still the gold standard for DTT training.
You can run it on Zoom, send a checklist, or trim rehearsal if time is tight.
Pick any package, then probe fidelity early and often.

03Original abstract
O ensino por tentativas discretas (discrete trial training, DTT) tem se mostrado efetivo para ensinar diversas habilidades para pessoas com Transtorno do Espectro Autista. O objetivo deste trabalho foi analisar os estudos recentes sobre o ensino da aplicação do DTT para profissionais e pais. Foram realizadas buscas nas bases de dados PsycInfo e ERIC com as palavras “discrete trial training”, “discrete trials”, “DTT”, “discrete trial”, “discrete trial instruction” combinadas com “developmental disabilities”, “autism” e “training”, no período entre 2018 e 2023. Quinze estudos atenderam aos critérios de inclusão. O behavioral skills training (BST) foi o procedimento mais utilizado e a telessaúde vem sendo utilizada para minimizar a necessidade da presença de um treinador. Além do BST, outros procedimentos se mostraram efetivos para ensinar a aplicação do DTT. Pesquisas futuras devem comparar os diferentes procedimentos e identificar variáveis envolvidas nas vantagens e nas desvantagens de cada procedimento.
