Objective: This article examines the efficacy of language intervention services for monolingual and immigrant children in a public clinic in Montreal, Canada. Intervention is provided in French for a preset number of sessions regardless of intervention needs. The study assessed immediate gains after intervention, their maintenance over 2 months, and their effect on diagnostic status at both time points. Methods: Participants included 15 children (57.7 months SD 7.8) diagnosed with developmental language disorder: 3 monolinguals and 12 bilingual immigrants. Intervention targeted vocabulary and syntax. Assessment of intervention targets and standardized testing was conducted before, after, and 2 months after treatment. Diagnostic status and severity level were assessed at each time point. Results: Intervention was highly efficacious with large effect sizes for intervention targets. However, for diagnostic status, efficacy was more questionable. Seven children improved their diagnostic status from pre- to posttest; but many dropped back at maintenance point. For 3 children, all test time showed scores within the non-impaired range, indicating misdiagnosis or change in status while waiting for treatment. Amount of pain was not correlated with any background variable. Conclusions: Results suggest that intervention could be more efficacious by giving more therapy sessions and conducting evaluation and treatment closer in time. [ABSTRACT FROM AUTHOR]
