There is a continuing interest in the link between communication difficulties and social, emotional and behavioural difficulties (SEBD). The literature indicates that speech and language therapy (SLT) can be effective, but there is also evidence that the communication needs of children with SEBD are likely to go undetected. Little is known about the opinions of speech and language therapists (SLTs) working with these children. This paper draws on a small-scale study carried out in England. Data were collected using questionnaires and interviews in order to describe and explore SLTs' practice and opinions. The results of the study could be used to improve practice and have implications for future research. (Contains 3 figures and 5 tables.)
