Further study details as provided by Heidelberg University:

Primary Outcome Measures:
  • Receptive and expressive language abilities using standardized instruments (SETK-2, SETK 3-5, AWST, HVS, HASE, HSET) [ Time Frame: at 2; 6, 3, 4, 5 and 8 years of age ]

Secondary Outcome Measures:
  • Parent-report screening questionnaire ELFRA-2 (adoption of the MacArthur Communicative Development Inventories-CDI); cognitive and social-emotional development assessed by standardized instruments, [ Time Frame: at 2;6, 3, 4, 5 and 8 years of age ]

Enrollment: 150
Study Start Date: October 2003
Estimated Study Completion Date: October 2011
Primary Completion Date: February 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.
Other Name: Early language intervention
No Intervention: 2
Waiting group, no intervention until children were three years of age

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.
