The main aim of the survey was to extend the 2007 Adult Psychiatric Morbidity Survey (APMS) prevalence estimate of autism among adults aged 18 years or over, to include adults with learning disabilities aged 18 years and over living in private households or communal care establishments. Fieldwork was carried out in Leicestershire, Lambeth and Sheffield between August 2010 and April 2011. The specific objectives of the study were:to identify a representative group of adults with learning disabilities who were either: (a) living in private households but not able to participate in the APMS 2007 due to learning disability; or (b) living in communal care establishments and thus not covered in the APMS 2007 sample;to interview the adults with learning disabilities living in private households who would not have been able to take part in the APMS 2007 with two clinical assessments for autism (depending on ability level) - module 1 or module 4 of the Autism Diagnostic Interview Schedule (ADOS);to interview carers of a sub-sample of adults with learning disabilities with two validated clinical assessments to calibrate module 1 of the ADOS;to combine the acquired prevalence rates of autism in adults with learning disabilities who live in private households and who live in communal care establishments with the prevalence of autism in adults without learning disabilities living in private households (from the APMS 2007) to derive an overall prevalence estimate for autism among adults;to perform sensitivity analyses of the combined prevalence estimate to take into account adults without learning disability who live in communal care establishments.;The main APMS 2007 study is held at the UK Data Archive under SN 6379.
