Objective: To investigate the effects of small group speech therapy consisting of two children in aspects of language and social development and identify powerful predictors for maximal therapeutic gains of two-person small-group speech therapy (2-SST).Methods: We retrospectively reviewed the medical records of 51 children, who had participated in 2-SST. Language and social abilities of children were assessed using multiple scales at initial and follow-up visits after participating in 2-SST program. Receptive and expressive language were measured using the Preschool Receptive-Expressive Language Scale and the Receptive-Expressive Vocabulary Test, while social abilities were assessed with the Social Maturity Scale.Results: Participants in the 2-SST showed significant improvements in all categories of receptive/ expressive language and social abilities. Multivariable linear regression analysis revealed that the same diagnosis and baseline receptive language ability difference and intellectual ability difference from paired-child were powerful predictors of improvement in receptive language ability. Younger age (≤5 years) was a powerful predictor of improvement in expressive language ability. Older age (>5 years) was an independent predictor of improvement in social ability.Conclusion: The 2-SST can be an appropriate delivery model to improve language and social skills with advantages of both individual and group speech therapy. For maximal therapeutic gains of 2-SST, same diagnosis, similar language and cognitive level with paired-child, and age should be considered depending on the more specific goals of treatment.
