Brief Summary:
The purpose of the study is to examine the effectiveness of a highly-structured parent-based language intervention group program for two-year-old children with language delay.

Condition or disease Intervention/treatment Phase
Language Delay Developmental Language Disorders Other: Heidelberg Parent-based Language Intervention HPLI Phase 3

Detailed Description:

Language delay in toddlers is a prevalent problem for pediatric practitioners. As there are no clear guidelines to deal with this problem, in German speaking countries the "wait-and-see"approach is widely chosen, although longitudinal studies have found that children with language delay are at risc for cognitive, behavioral and social-emotional problems.

During the last few years various forms of early language intervention have been increasingly implemented in German speaking countries. However, they have not been evaluated.

Early parent-based intervention could be an economical way in prevention speech and language disorders.

Arm Intervention/treatment
Experimental: 1
The mothers of the two-years old children in the intervention group took part at the Heidelberg Parent-based Language Intervention HPLI
Other: Heidelberg Parent-based Language Intervention HPLI
The HPLI is a group program for parents of young children with language delay. This 12-14week program includes seven two-our sessions and one three-our session six months later. It is designed for 5 to 10 people and based of an interactive model of language intervention, wich presumes that optimized parental input will provide better language-learning opportunities.
