Where Did We Come From? Difficulties with clinical questions and searches Dearth of positive useful data Multiple baseline designs Topics covered included phonological awareness, models of service delivery, long term effects of language disorder, language therapy techniques, parent training On the path to a CAT
Where Are We?? Our CATs to date What is the most Effective form of treatment for 4 year olds?… Word Finding Difficulty… EI SDM – Parent Training vs Clinician Led Rx vs No Rx
Lost in the NH&MRC How can we achieve NH&MRC 1? What makes a “pseudorandomised” control trial in language?
A Good Trek Vasilyeva, M., Huttenlocher, J., & Waterfall, H. (2006). Effects of language intervention on syntactic levels in preschoolers. Developmental Psychology, 42(1), Level II Current research Still lots of questions (weaknesses) arose from it. Study didn’t determine if the participants had any underlying language, development, or emotional/behavioural difficulties Poor comprehension task – not statistically strong data
A Good Trek Hodge, T. & Downie, J. (2004). Together we are heard: Effectiveness of daily ‘language’ groups in a community preschool. Nursing and Health Sciences, 6, Level IV Weak research but clinically good Australian The program wasn’t referenced, extraneous variables weren’t controlled for & there was no control group – why not? Multiple baseline design??
A Poor Trek Telleen, S., Wren, C. (1985). Acquisition of prepositions in language delayed preschoolers: is intervention effective? British Journal of Disorders of Communication, 20, pg No strengths! Couldn’t give it an evidence rating!!! No control groups or randomisation No statistical analysis Poor description of procedure – testing, therapy, criterion Poor description of subjects: reason for cognitive delay and there was a huge range Poor inclusion/exclusion criteria - No information regarding other services the children were receiving i.e. SP
Our Challenges Lack of good research Where are the randomised control trials?? Clinical Questions Need to be specific Lots to cover Slow progress – is it more effective?
Where Are We Heading? General comprehension Auditory Processing Disorders Looking at the evidence for specific therapy programs – ‘Blades’ and ‘Prompt’ School language / Curriculum Based Learning
