New research suggests that sustained speech therapy helps two-thirds of autistic children develop spoken language, with the duration of treatment proving more important than intensity.
Researchers from Drexel University in Philadelphia tracked 707 autistic preschoolers aged between 15 months and five years.
The study, published in the Journal of Clinical Child & Adolescent Psychology, evaluated children participating in intervention programmes such as the Early Start Denver Model and TEACCH, which utilises visual cues to enhance communication.
The results showed that 2 out of 3 children (66%) who were non-speaking at the start learned to say single words after attending sessions for roughly 10 hours a week over six months to two years.
Furthermore, half of the children who began as "minimally speaking" progressed to combining words into phrases.
Dr Giacomo Vivanti, the study author, emphasised that consistency over time yielded better results than high-intensity, short-term courses.
He noted that the ability to imitate sounds and actions was a strong predictor of future language success.
"When parents ask me if their child should do these interventions to gain spoken language, the answer after doing this study is still yes," Dr Vivanti said.
However, he cautioned that one-third of participants did not make significant linguistic progress, highlighting the need for tailored support for these people.
