Screening for primary speech and language delay: a systematic review of the literature.

Screening young children for developmental conditions such as speech and language delay is considered to be a part of the Child Health Surveillance programme in the UK. It is currently practised in many different ways throughout the country and like screening for other conditions conventionally identified in infancy, has been the subject of some concern for those responsible for providing such services. This systematic review (Law et al. 1998) was hypothesis driven and aimed to: i) establish whether, given the available evidence, there was sufficient evidence to warrant the introduction of universal screening for speech and language delays in children up to seven years of age; ii) identify gaps in the available literature; iii) identify priority areas in need of further investigation and iv); provide evidence-based recommendations for the future provision of services.
