@adamfilip Whilst there aren’t any specific prevalence figures in relation to PDA, it is thought to be relatively rare. There was one small study conducted in the Faroe Islands: https://t.co/2aY249pBOC If we can help with anything else please let us know:
@HappeLab Also contradicting Gillberg et al (2015) prediction that PDA can be seen in up to a few percent of human populations. Also Gillberg's view PDA is common and possibly a new type of childhood disorder. https://t.co/vqlvQ2NlRp & https://t.co/mg5
See Newson et al (2003): https://t.co/mfYvYdWHVH O'Nions et al (2014), with the EDA-Q validation paper. https://t.co/OaiNSvCQc5 Gillberg et al (2015) for Faroe Islands paper: https://t.co/vqlvQ2NlRp https://t.co/kuXXZsd0g2
That Gillberg mention it here: "However, the apparently socially manipulative behaviour is not characteristic of ASD, and is, in fact, by some, considered to be an exclusionary criterion for a diagnosis of ASD." p980. https://t.co/vqlvQ2NlRp https://t.co/r
Wording for some of the original PDA DISCO questions is available. Q14 "Socially shocking behaviour with deliberate intent (2) and (3)", not with intent part, which denotes manipulation. https://t.co/vqlvQ2NlRp https://t.co/ORja6nFw1N
This makes sense considering they acknowledge Newson included non-autistic persons in her database. https://t.co/vqlvQ2NlRp https://t.co/cJ6eev23sR
@CliveEaton @cassie_davies @DrJudes03 @AnnMemmott Baring in mind most of the predicted PDA populations are based on lower diagnosis thresholds than Newson, as Newson said everyone who has PDA has socially manipulative demand aviodance. https://t.co/mg5Vd3Q
@tinkerbellbites @milton_damian @martinbeecher @GillLoomesQuinn @PDASociety @sallyrssll Also note that Faroe Islands paper did not view manipulative demand avoidance as essential for a PDA dx. Some would challenge if Gillberg et al dx PDA. https://t.co/vql
Original DISCO Demand Avoidance question, in clinical format. We can tell it is original as it correspondences to wording used in Faroe islands population study that used original 15 PDA DISCO questions. https://t.co/vqlvQ2NlRp https://t.co/KWMF23FSas
For PDA prevalence rates, we only one set of figures available from Gillberg et al (2015). It had 9 out of 50 autistic persons having a PDA dx. Gives us a prevalence rate of 18% for autism. https://t.co/vqlvQ2vKsP https://t.co/fUF4PQO0hy
@cassie_davies @GillbergCentre @DrJudes03 Why are there important clinical differences between PDA & autism? Because it PDA is a Pervasive Developmental Coding Disorder & not autism. https://t.co/keA9GBmiap
Also @GillbergCentre view on how common PDA is: https://t.co/mg5Vd3QbML & https://t.co/vqlvQ2NlRp https://t.co/HzB3ErTsnh
https://t.co/vqlvQ2NlRp Help4Psychology PDA database is poor quality, circular & open to confirmation bias. https://t.co/YP9joNjDZK & https://t.co/nowIUCC4FY
I think PDA is likely to be something new as suggested by Gillberg here: https://t.co/mg5Vd3QbML I am unsure if PDA is as common as suggested here (up to a few percent of human population): https://t.co/vqlvQ2NlRp
Again maybe PDA maybe a common condition upto a few % of human population: https://t.co/Oodjk52OA4
@Andylowarousal @richardmills18 @milton_damian @liz_pellicano Link: https://t.co/vqlvQ2vKsP and https://t.co/mg5Vd3yAob What is clear there is a need for good quality rigorous scientific-method based research on PDA. https://t.co/3i9tu97oBt
No idea if the 17 DISCO items are typo or 2 were removed for whatever reason. Other 15 are mentioned: https://t.co/LMOaO0xKgl & https://t.co/vqlvQ2NlRp https://t.co/6bBl5b9c6p

Also quite important is that the original 15 PDA items for the DISCO were used in a population study, i.e. it can differentiate between autistic persons. https://t.co/vqlvQ2NlRp
Links to respective PDA DISCO articles: https://t.co/LMOaO0Pl7T and https://t.co/vqlvQ2vKsP So I tabulated the respective entries for each article and cross-checked against relevant entries from a took based off 15 DISCO items. https://t.co/tOYVqDHdZc
Yet we know from their own research main PDA tools are designed to assess for Newson's dx traits: https://t.co/LMOaO0xKgl and https://t.co/vqlvQ2NlRp For a PDA dx to be valid, need to use Newson's PDA criteria over criteria advocated by PDA Development Gro

@NeilKenny0 @Andylowarousal @gdmorewood @caeruseducation @Allison66746425 Specific things that are ignored, that are relevant to PDA. Certain authors have written about why it is problematic fitting PDA into autism spectrum: https://t.co/bBM6TBSMxu and htt
If people need a better image of Newson's "Autistic Family" diagram. Also 15 unvalidated DISCO PDA items, also need the full DISCO as questions to assess for delayed speech development are in full DISCO. https://t.co/vqlvQ2NlRp https://t.co/RRGCuE2MDD
Finally, one would expect that if @GillbergCentre conducted the study, diagnosing it in non-autistic persons, they would see many more PDAers including non-autistic ones: https://t.co/Oodjk52OA4 https://t.co/CKyxptwvy2
