PDA (Pathological Demand Avoidance) is widely understood to be a profile on the autism spectrum, involving the avoidance of everyday demands and the use of ‘social’ strategies as part of this. PDA individuals share autistic characteristics and also have many of the ‘key features’ of a PDA profile. We provide information, support and training about PDA for individuals, families and professionals. We aim to increase acceptance and understanding of a PDA profile and to improve outcomes for individuals and families by focusing everyone involved on ‘what helps’. Each year we answer around 2,300 enquiries from people seeking support and deliver training to 2,400 parents, carers and professionals. Our information resources reach 500,000 people a year via our website and social media. All our services are run by the PDA community and include: • an enquiry line • an online forum • information resources • training • conference every other year We also share good practice, work in partnership with other organisations and promote research on PDA.
