A blog that explores the concept of PDA as well as offering an insight into life with a child with PDA

The first ever PDA Society Parent Conference was held on the 23/09/15 at the Park Inn by Radisson and what a day it was!  I have never, ever attended an event before that was so emotionally charged from beginning to end!  The work and organisation that had gone into this conference by the PDA Society Committee was simply outstanding.  How this group of people managed to organise and host such a professional and knock out conference while simultaneously balancing family life with their own children with PDA, often in conjunction with jobs and running the PDA Society is nothing short of amazing!

The PDA Society had wanted to provide parents with a conference that would differ from the professional PDA conferences and this was pulled off and then some…. It was a conference of warmth, emotion, togetherness, tears and laughter with many memorable moments and some very special touches.

The opening short film, which was a compilation of parental quotes and pictures of individuals with PDA and parents of individuals with PDA, set to the music of ‘what doesn’t kill you makes you stronger’ really was an emotional opener and set the tone for the whole day.  From that point on I think that many of us were charged up to the max and riding on the wave of a most incredible buzz.

On each table were strips of coloured paper for each parent to write on stating what things gave them strength.  A huge paper chain was to be made from all of the completed strips but it wasn’t until the end that the reasons for this would be revealed.  There were also some other really nice touches like raffles and prizes for different things which again gave the conference a really lovely flavour and differentiated it from your standard conference.

There were four presentations throughout the day which were really nicely balanced between professionals and parents.

Phil Christie, Consultant Child Psychologist got things off to a flying start with the opening presentation talking about the history of PDA, information on recent and ongoing research, where PDA now sits on the spectrum as well as some really lovely insights about how we can better understand what drives the behaviour for our children with PDA.

Jo Clarke, PhD., Director of Petros: Resilience for Life was on next and gave a very fabulous and witty presentation discussing the Dr Ross Green model for parenting based on the premise that ‘children do well if they can’ and how the use of collaboration and flexibility with your child towards a better shared understanding of each other can be so hugely beneficial for all concerned.

Following Phil and Jo’s presentations the parents attending all went to have a break, attend their preferred workshops and then have lunch.  The idea of workshops in additions to the presentations was a stroke of genius.  Not only could parent’s attending listen to the speakers but they could also get specific information, in small groups, on a variety of subjects that affect the daily lives of families living with PDA like sensory issues, siblings, de-escalation techniques, sleep and educational issues to name but a few.

I was up next and yes I was shaking with nerves and just hoping that by hook or crook I would get through it without completely losing the plot or going completely blank.  I have only ever done one presentation before which was to about 25 people and so speaking to 250 people including the likes of Phil Chrisitie, Ruth Fidler and Jo Clarke was a bit of a steep curve to face head on to say the least.  The theme for my presentation was about developing the confidence to parent the PDA way and after a shaky start I managed to get into my stride and even ran over my allocated time.  I had practiced and practiced at home and had even struggled to spin things out for my allocated 20 minute slot and so running over was somewhat of a miracle.  My apologies to anyone on the day whose workshop time was affected by running over, I was simply in a haze of fear and forgot about anything and everything else in a bid to get through my presentation in one piece.

Here are the slides from my presentation.
Parenting the PDA Way

Next up was Neville Starnes, PDA Society trustee and creator of the “bluemillicent” YouTube videos.  As ever Neville presented a beautifully written and humerous presentation.  His use of words and language was both profound and poetic striking a chord with many parents.   He finished off with a really funny comparison between the PDA diagnostic criteria and how the behaviour of many education authorities actually perfectly fits this criteria.  It was a lovely way to finish the presentations with humour and laughter.

Following the speeches the parents went to their respective workshops and I practically did a Usain Bolt to the bar for a much needed glass of vino.  It was here that I had one of my very special memories of the day when I shared an emotional hug with a parent who has found my ramblings over the past few years helpful.

The day finished off in much the same way that it had started, emotional and uplifting.  Myself, Neville, Deb West and Margo were all surprised with a lovely gift each for our support to parents, during the past few years for me and going even longer back for the others.  Then the music piped up again ‘what doesn’t kill you makes you stronger’ and the video began to play all of the comments of support and thanks from many parents.  The paper chain, now complete and all strips linked together, was held aloft and past from the front of the room to the back in a Mexican style wave move as the music and video continued to play.  Wow what a moment, what a feeling and what a way to end the most amazing conference.

The conference had come to an end and what a buzz it was, time to have a chill with a few of the others in the bar and savor the memories of the day.


Special thanks from me to everyone who put this conference together and for the honor of inviting me to speak.  Also a huge thank your for the massive support that was given to me both before, during and after my presentation from so many people and to the parents who came over to say hi. It was lovely to meet you all and to be able to put real life faces to so many facebook profiles.



Many individuals with PDA appear to go into complete free-fall during a certain stage of development.  The time that this period of free-fall ensues can vary from individual to individual.  Mollie’s period of free-fall was between the ages of about 6-10 years old.  Now don’t get me wrong, prior to free-fall she was extremely challenging, difficult to handle, avoidant of many demands, required constant attention, had numerous meltdowns both at home and at school and had boundless energy. However from the age of about six years old everything dramatically nosedived.  I put this down to a combination of the increasing demands of society for age appropriate behaviour exceeding her ability to cope combined with an increasing awareness of her difficulties and how others viewed her.

The signs of free fall from my experiences of PDA were as follows

  • An increasing need for full control at all times over her own environment and the people in it
  • Avoiding demands increased and escalated to anything and everything
  • She almost appeared to regress before my eyes.  What she could achieve at five years of age she was unable to achieve at 7 years of age
  • Really inappropriate behaviour began to escalate E.G. urinating in inappropriate places.
  • School refusal began at age six and continued
  • Huge issues surrounding sleep began at age six
  • Refusal to leave the home full stop began at about age seven
  • Meltdowns escalated to multiple times a day last for an hour or more over the tiniest of issues
  • Her need to cut me off from other people intensified to a suffocating level

At this stage, and it may happen at various ages depending on the individual, it is important to stand back and to take stock of the situation rather than to try to change the behaviour or to let things develop into a battle of wills.  These are the warning signs that a complete crash maybe imminent.  How you proceed now could alter the path for the future of the child. During this time much damage can be done by proceeding in the wrong direction and this can take years to undo. Alternatively proceeding down the correct path could significantly reduce the damage and make the road to recovery shorter and less bumpy.

What you can do at home

  • Reduce demands to a level that are tolerable for the child.  For some children minor adjustments may need to be made but for others a drastic reduction of demands may be the only option.
  • Really try to focus on what things are really important and what things can be relaxed on, negotiated or when full control may need to be given to the child.  This list will vary depending on age, personal circumstances and the severity of PDA exhibited by the child.
  • Try to make home as PDA friendly as possible, therefore creating a calm environment for the child.  This may mean completely adapting your way of living and what you consider to be the norm in order to fit in with the child with PDA rather than expecting or hoping that the child with PDA will adapt to your normal living environment.
  • The needs of adults may need to take a back seat in the short term but the needs of siblings may still need factoring into the equation.  The needs of siblings may become a non negotiable boundary.

What you can do about school

  • If your child has become school phobic and is increasingly distressed about attending school then continuing to try to get them into school may cause more harm than good.
  • The school may need to change their approach to the child and put the appropriate measures in place.  School refusal due to school phobia is classed as a health issue and needs addressing by the school in the form of them adjusting the environment for the child in school and making reasonable adjustments.
  • If the school are unable to adapt or to put the appropriate support into place then if it is possible remove your child from school until a full understanding of your child’s difficulties and the appropriate measures that need to be put into place have been established.
  • Don’t let local authorities, schools or welfare officers bully you with the threat of fines and prosecution.  Your child is not in school for a valid reason and this is different to truancy. The local authority has a duty to provide your child with an education, possibly at home, in the interim.  This may not need to be a formal education but could be one that simply aims to re build and re establish trust and relationships. This previous post of mine may help re this situation http://understandingpda.com/2015/03/25/school-refusal-knowledge-is-power/
  • If your child is not already on the SEN register request that he or she is placed on it and that an Individual Education Plan (IEP) is put into place.
  • If your child is already on the SEN register then he or she should be able to access an additional £6,000.00 worth of funding per annum.  If this funding is not being allocated to your child respectfully request that it is. If the school say that they don’t have the funds suggest that the school apply to the LA in order to have a top up on their SEN funding. This document goes into more detail re SEN funding and was kindly shared with me by another parent http://www.councilfordisabledchildren.org.uk/media/409191/cdc_funding_briefing_for_parents_-_final.pdf
  • If you feel that what the school can offer your child from their SEN funding falls short of the mark then apply for an Education Health and Care Plan (EHCP) in order to secure further funding to support your child. If your child is achieving academically then focus on the fact that their emotional needs and well being are not currently being met as stipulated in the SEN guidelines.Paras 6.28 to 6.35 describe the four broad areas of need that should be considered: – Communication and Interaction – Cognition and learning – social, emotional and health difficulties – sensory and/or physical needs 6.45 – (talking about the school’s assessment) It should also draw on … the views and experience of parents, the pupils own views and, if relevant, advice from external support services. Schools should take seriously any concerns raised by a parent.6.17 – Class and subject teachers, supported by their senior leadership team, should make regular assessments of progress for all pupils … 6.18 – It can include progress in areas other than attainment – for instance where a pupil needs to make additional progress with wider development or social needs in order to make a successful transition to adult life.

Most EHCP’s are refused first time around but you can then go to mediation or appeal the decision.  Don’t give up and follow each and every process through to the bitter end.

Securing the correct support for your child can be a long and tedious process but it can be achieved with persistence and tenacity.  If you look at the process like a ladder then this can help, you can’t miss a rung out in your journey to the top but instead you may have to step on each and every rung during your climb in order to correctly fulfill the pathway to support.

Even with all of the above in place it can take years before tangible differences can be seen so please don’t expect quick results. Sometimes, regardless of the strategies and environment put in place for the child, it can be a case of waiting for the maturing years of the child to catch up.

Good luck in your journey and remember, never give up!

These are exciting times indeed for the PDA Community.  At long last this condition is finally gaining some recognition and mainstream media coverage.  Unfortunately along with this comes the usual and expected harsh, hurtful and uneducated comments from the ignorant, those who are simply blinkered and unwilling to learn or to understand.

 photo dont-judgemp2_zps8zvfxjhr.jpg
To all of the wonderful parents out there who are living with PDA on a daily basis please, I implore you, simply ignore such rubbish and turn the other cheek.  We know and we understand each other and what an amazing job we do in such incredibly trying and difficult circumstances.  We are actually the polar opposite of bad parents because we have to be amazing parents in order to simply survive each day while simultaneously nurturing, guiding and managing the most complex of children.  Not to mention factoring in the extra skill of often having to be our child’s teacher, advocate, physiologist, psychiatrist and occupational therapist all rolled into one.

Although this awareness will bring out the worst in the ignorant it will, on a positive note, help to transform the lives and long term prospects of so many children and their families. So if we ignore the bleating’s of the bad parenting brigade and focus only on the positives then only good can come out of this exciting time.

When I discovered PDA, five years ago, awareness was very thin on the ground and information and support on the net consisted of the PDA Society (formerly known as the PDA Contact Group), the National Autistic Society (who still had PDA in their related conditions section), Autism East Midlands ( formerly known as Norsaca), The Maze and the wonderful You Tube videos by Neville Starnes https://www.youtube.com/channel/UC6m8JcNEqX6e-2uBHE25BFw.  Since then awareness has steadily grown and now it is absolutely mushrooming.  I must confess that I did wonder if I would see this during my lifetime and I am stunned at how fast that it has all appeared to suddenly come together.

I can only hope that this coverage not only raises awareness for distraught parents who are desperately trying to understand their child’s complex and confusing behaviour but that it also raises awareness among professionals.

In the support group that I help to run we are having more and more parents joining us who have had professionals suggest PDA to them, in relation to their child’s difficulties, which is greatly encouraging. It wasn’t so long ago that NO professionals appeared to have heard of PDA.  It really was a case of parents trying to educate the professionals and becoming increasingly frustrated at hitting brick wall after brick wall.  Also, as a parent, when it dawns on you that your knowledge has become greater than the professional who you are turning to for support it does not instil a sense of confidence at all.  So let’s just hope that this is a massive turning point for awareness and acceptance of PDA within the professional community also.

With special thanks to Elizabeth Newson, Phil Christie, Ruth Fidler and the PDA Society for their long term efforts to get PDA recognised, accepted and for leading PDA to where we find it today, PDA is coming out of the shadows.

Also thank you to Dr R Jayaram, Dr D Harper and Maverick TV for making a very sensitively approached series and for being brave enough to go public with PDA and to stamp their colours well and truly to the PDA mast.

Fantastic and amazing post by Dinky’s mum in answer to all of the uneducated people who think that kids with neurological conditions are simply naughty and why a different way of parenting is what is needed rather than the old fashioned way which just does not work!!!

Originally posted on Dinky and Me:

Dinky has been diagnosed with autistic spectrum disorder-pathological demand avoidance, attention deficit hyperactivity disorder and sensory integration difficulties (also known as sensory processing disorder).

Or for short


Here in the UK there is a documentary series called ‘Born Naughty?’ (Click here for some info on the programme which features children with ASD-PDA)
There are so many comments like :

’No child is born naughty-it is a parenting issue.’

To an extent they have a point, but not in the way they think… Let me explain…

There was an issue with my parenting… I was made to believe that the only right parenting strategies were those for typically developing children. That was mistake number 1.

I read up on challenging children, watched supernanny and implemented lots of new behavioural strategies. They didn’t work.

Then I found out about PDA, had my lightbulb moment and this came with…

Well my last post on Mollie and her progress was so positive that even I could not believe the huge steps forward that Mollie was making.  But then the period of ‘shutdown’ that is so familiar to so many parents, hit us with a much unexpected boom!!!

She had achieved so much but then she completely shut down and retreated to her room for several weeks.  When this happens I am often perplexed and confused on how to move on in a successful manner.  A few days of shutdown is one thing but a few weeks, not knowing when it will end, is another thing all together.

It was time to reassess and to re-group.  Ok, so she had done tremendously well in accessing a home Education group, groups for children with emotional difficulties, playing out, going for walks and so on.  I really and truly believed that we were out of the woods when it came to self-imposed social isolation but I was oh so wrong!

The anxiety associated with accessing the outside world coupled with difficulties playing on line with peers ultimately took their toll.  She endured and she controlled herself but this only resulted in her needing major down time in order to recover from the onslaught of the NT world.  The good news is that difficulties with social interaction no longer involve meltdowns of indescribable proportions, the bad news is that they do involve self-harm and a need to completely hide away.  Difficulties are now internalised rather than externalised.  She removed herself from the world and her skin on her arms and face have been picked and picked and picked.

I have cried, I have worried and I have been at a loss of what to do next for the best.  Do I leave her to come out of this situation naturally and in her own time or do I try to speed up the situation?  As ever, with PDA, there are no wrong or right answers, as parents we can simply only go by out gut instinct.

I left her to it but also went to efforts to reassure her and to remind her that I was here and that she was not alone. I sought advice from a fellow parent whose child also has an extreme presentation of PDA and she also helped to advice given her experiences of her own child.  Mollie’s sleep was completely upside down and so it was hard to reach or to engage with her given that she slept during my waking hours.

I began to use the first few hours of the morning when we were both awake to simply sit next to her while we both coloured.  I didn’t instigate communication or present demands we just sat quietly and coloured in together.  In silence and without words she knew that we were together come ever what would be.

Eventually she began, very slowly to re-integrate back into family life.  Wanting to watch a film with her dad or asking me to do something with her all became positive steps in the right direction.   In fact just coming downstairs and leaving the comfort of her bedroom or mine, whichever one she had chosen for safety, became a major achievement and a sign that things were moving in the correct direction.

On Saturday Mollie came to a craft fair with me in order to sell our glass art. On Sunday she was up and about watering the garden, going out with her dad to take pictures and basically seeking more social engagement.  Today she showered, washed her hair and wanted to go out. We have spent a lovely day together shopping, eating out and watching quizzes on TV.

As ever the cycle of social interaction and the need for ‘down time’ continues and from this I continue to learn.  The good news is that periods of ‘down time’ are shorter (weeks rather than months or, in the past, years) and the periods of ‘out time’ are longer and more successful.

It really is a case of two steps forward and one step back but the ratio of 2:1 ensures that we are moving in the correct direction.

This is a picture of Mollie today and how she feels about herself.  Underneath the robust exterior of a child with PDA is often a very fragile ego which this picture and the accompanying comments explains in such a concise and honest way.

Today I got out of bed had a shower 💆brushed my teeth put some make up on and I looked in the mirror and litchory I sore a completely different person for the thirst time in my life through my eyes I looked pretty xx

Please remember when reading Mollie’s text that she is severely dyslexic and has not received a formal leaning education from the age of six.  I think that her literary skills are amazing considering that she is dyslexic and self taught in reading and writing.  I can only hope that my followers feel the same.

Thank you for reading this blog post and for following our journey,  I can only hope that it helps those who follow in our footsteps.  I would also like to add that parent power and knowledge is so very important because we often only have each other to rely upon. Other parents often turn to me for advice and strategies and when the shit hits the fan it is other parents that I turn to.  Hopefully, one day, the professional world will catch up with our unique and extreme difficulties and be able to support and offer us advice with regard to our deeply complex children also xxx

Why Pathological Demand Avoidance Syndrome (PDA) is not the same as, or another way of, describing Oppositional Defiant Disorder (ODD)

PDA was proposed by Professor Elizabeth Newson to be seen as a definitive and separate sub group within the category of ‘Pervasive Developmental Disorders (PDD)’ (Newson et al 2003). Elizabeth Newson et al (2003) Pathological Demand Avoidance Syndrome: a necessary distinction within the pervasive developmental disorders; Archives of Diseases in Childhood. Since the publication of this paper terminology has changed and the term PDD has become synonymous with the term ASD.  The importance of this is that PDA is now best understood as being one of or part of the Autism Spectrum Conditions (P Christie 2015).

PDA is not currently thought of, by the experts in this field, to be another name for ODD or to be another name to give to an individual with ASC and co morbid ODD.  It may be that some individuals do indeed present with ASC and co morbid ODD however this may not always be the case.  A child with PDA will have a unique profile that may not be accurately described or indeed helped by the mix and match of these two labels. 

“It is inevitably the case that when conditions are defined by what are essentially lists of behavioural features there will be interconnections and overlaps. Aspects of both of these conditions can present in a similar way to those features that make up the profile of PDA.  There is also the possibility of the co-existence or ‘co-morbidity’ of different conditions and where this is the case the presentation is especially complex.

ODD, Oppositional Defiant Disorder, itself often exists alongside ADHD, and is characterised by persistent ‘negative, hostile and defiant behaviour’ towards authority.  There are obvious similarities here with the demand avoidant behaviour of children with PDA.  PDA, though, is made up of more than this, the avoidance and need to control is rooted in anxiety and alongside genuine difficulties in social understanding, which is why it is seen as part of the autism spectrum.  This isn’t the case with descriptions of ODD.  A small project, supervised by Elizabeth Newson, compared a group of children with ODD and those with a diagnosis of PDA and found that the children with PDA used a much wider range of avoidance strategies, including a degree of social manipulation. The children described as having ODD tended to refuse and be oppositional but not use the range of other strategies.  Many children with ODD and their families are said to be helped by positive parenting courses, which is less often the case with children with PDA.”  (P Christie 2015 ‘My Daughter is Not Naughty’ p.g 310 – 311)

Recent research has concluded that there are indeed behavioural overlaps between individuals with PDA, typical ASD and ODD but that the PDA group had unique features that were not shared by either of the other two groups and that the PDA group were also atypical of the behavioural profile typically seen in individuals with ASD or conduct problems.

The findings of this research have being summarised in the following information cards and the source for that information is referenced in the cards.

Further discussion From the Published Research that was the Source for my Information Cards

While these findings could indicate that the PDA group has an ASD with co-morbid conduct problems, plus additional extreme emotional symptoms, this does not fully accommodate the main difficulties in PDA as outlined in the ‘Introduction’ (of that research paper). Specifically, poor social cognition associated with autism appears inconsistent with instrumental use of social manipulation. Impoverished imagination in autism is inconsistent with role play and excessive fantasy engagement in PDA (e.g. taking on the role of a teacher when interacting with peers and telling tall tales). While children with conduct problems may resist complying in order to pursue their own interests – for example, to avoid a task they dislike – obsessive avoidance of even simple requests, regardless of the personal consequences, goes beyond this. PDA may represent a subset of those who tick boxes for ASD, conduct problems and emotional symptoms, with these additional very characteristic problematic features. However, current educational or therapeutic provision for ASD children with conduct problems does not seem to suit those described as having PDA. The term may well reflect disturbances in more circumscribed socio-cognitive pathways associated with social reciprocity or processing of incoming social cues. These hypotheses must be explored using cognitive-level paradigms. Elucidating the neurocognitive basis of this profile, and possible interventions, remain key issues for future research. O’Nions E, Viding E, Greven CU, Ronald A & Happé F (2013) Pathological Demand Avoidance (PDA): exploring the behavioural profile; Autism: The International Journal of Research and Practice.

As a result of recent research there has also been the development of the Extreme Demand Avoidance Questionnaire EDA.  O’Nions, E., Christie, P., Gould, J., Viding, E. & Happé, F. (2013)  Development of the ‘Extreme Demand Avoidance Questionnaire’ (EDA-Q): Preliminary observations on a trait measure for Pathological Demand Avoidance; Journal of Child Psychology and Psychiatry. 

The EDA-Q was found to successfully differentiate children reported by parents to have been identified as having PDA from comparison groups reported to have other diagnoses or behavioural difficulties. It provides a potentially useful means to quantify PDA traits, to assist in identification and research into this behavioural profile.

Key points

• Pathological Demand Avoidance (PDA) is a relatively new term that is increasingly being used as a clinical description in the United Kingdom. Children with PDA display an obsessive need to avoid everyday demands, and try to dominate interactions with others, often using socially shocking behaviour with apparently little sense of what is appropriate for their age.
• The present study describes the development and preliminary validation of a trait measure for PDA: the ‘Extreme Demand Avoidance Questionnaire’ (EDA-Q). Scores on this measure successfully differentiated individuals reported to have PDA from comparison groups reported to have other diagnoses or behavioural difficulties, including individuals with ASD, disruptive behaviour, or both. The sensitivity and specificity of the measure to identify PDA was good.
• The 26-item EDA-Q provides a potentially useful means to quantify PDA traits. Scores should be considered an indicator of the risk that a child exhibits the PDA profile, rather than a diagnostic indicator. Further studies are needed to validate the measure in a population for whom information from clinical assessments is available.

Extreme Demand Avoidance Questionnaire (EDA-Q): 26-item final version

Items 1–26 (apart from 14 and 20) are scored as follows: Not true = 0, Some-what true = 1, Mostly true = 2, Very true = 3. Items 14 and 20 are reverse scored: Not true = 3, Some-what true = 2, Mostly true = 1, Very true = 0. Total possible score for items 1–26 = 78.

Not true

Some-what true

Mostly true

Very true

1 Obsessively resists and avoids ordinary demands and requests
2 Complains about illness or physical incapacity when avoiding a request or demand
3 Is driven by the need to be in charge
4 Finds everyday pressures (e.g. having to go on a school trip/visit dentist) intolerably stressful
5 Tells other children how they should behave, but does not feel these rules apply to him/herself
6 Mimics adult mannerisms and styles (e.g. uses phrases adopted from teacher/parent to tell other children off)
7 Has difficulty complying with demands unless they are carefully presented
8 Takes on roles or characters (from TV/real life) and ‘acts them out’
9 Shows little shame or embarrassment (e.g. might throw a tantrum in public and not be embarrassed)
10 Invents fantasy worlds or games and acts them out
11 Good at getting round others and making them do as s/he wants
12 Seems unaware of the differences between him/herself and authority figures (e.g. parents, teachers, police)
13 If pressurised to do something, s/he may have a ‘meltdown’ (e.g. scream, tantrum, hit or kick)
14 Likes to be told s/he has done a good job
15 Mood changes very rapidly (e.g. switches from affectionate to angry in an instant)
16 Knows what to do or say to upset specific people
17 Blames or targets a particular person
18 Denies behaviour s/he has committed, even when caught red handed
19 Seems as if s/he is distracted ‘from within’
20 Makes an effort to maintain his/her reputation with peers
21 Uses outrageous or shocking behaviour to get out of doing something
22 Has bouts of extreme emotional responses to small events (e.g. crying/giggling, becoming furious)
23 Social interaction has to be on his or her own terms
24 Prefers to interact with others in an adopted role, or communicate through props/toys
25 Attempts to negotiate better terms with adults
26 S/he was passive and difficult to engage as an infant


For children aged 5 to 11 a score of 50 and over…
For children aged 12 to 17 a score of 45 and over…
…identifies individuals with an elevated risk of having a profile consistent with PDA.

‘The EDA-Q should not be considered a diagnostic test. For diagnosis, a thorough assessment by an experienced professional is required.’ (PDA Society 2014)


PDA is a very real condition that should be seen as a definitive and separate subgroup with the autism spectrum conditions.  Hopefully with continuing research, within this field, PDA will eventually and officially enter the diagnostic manuals. However, in the interim, there is nothing to stop many clinicians from diagnosing this condition based on their own clinical experience and expertise.

Being in a diagnostic manual is not a pre-exquisite required for diagnosis and should not prohibit a clinician from diagnosing PDA as stated by Dr Judith Gould at the Cardiff PDA Conference 2014.  Being in a diagnostic manual simply means that finally research has finally caught up, but this can take decades.  In the meantime many individuals and families are left without the correct diagnosis or support.

Although Asperger’s has being removed from the DSMV it isn’t that the condition has been deleted but simply that the terminology of individuals presenting with an Asperger’s profile has been changed.  However in 1970 this condition or even this profile may not have even existed in diagnostic manuals, does this mean that the condition didn’t exist or merely that it was waiting for diagnostic manuals to catch up with what Hans Asperger’s had already discovered? This is where we are now currently standing with PDA, we are simply waiting for diagnostic manuals and research to catch up with what Professor Elizabeth Newson identified some thirty odd years ago.

The importance of the correct diagnosis is to better understand the child and to be signposted to the correct support and strategies (P Christie).  Strategies that are often successful for individuals with ODD do not tend to be successful for individuals with PDA and can, infact, often intensify the issues.

My daughter is not willfully naughty or defiant and describes the need to avoid demands as instinct, something that she does not consciously decide to do but something that she is compelled to do.  When she is met with a demand, even a pleasurable one, her stomach goes into somersaults and in order to stop the rising anxiety she simply has to try to avoid the demand. Giving her a countdown or a routine of the day’s activities makes her even worse as does direct eye to eye contract and firm, simple and direct demands.  This may vary from child to child but these strategies do not work with her but PDA strategies do!

This information was originally collated by myself and Tom Crellin in order to assist a parent who was trying to seek validation with the professionals assessing her child that Pathological Demand Avoidance was a very real and valid diagnosis.  I have replicated this as a blog post in the hope that it can help other parents in their journey.

In the 1980’s Professor Elizabeth Newson coined the phrase PDA to describe a group of children who all displayed a unique cluster of symptoms.  During this period Professor Newson led the ‘Child Development Research Unit’ at Nottingham University.  The cases that were referred to her were often complex and had an unusual developmental profile.  The cases would often remind the referring clinician of a child with Autism or Asperger’s Syndrome but they didn’t quite fit this diagnostic profile in that they would often present with an atypical profile.  (‘Understanding PDA in Children’ P Christie, R Fidler, M Duncan & Z Healy 2011)
These children had better imaginative play and better social and communication skills (at a surface level) than you would typically expect to see in children with a typical presentation of ASC.  Indeed they had enough social insight and sociability to be able to manipulate others in their avoidance of demands and in order to remain in control of their immediate environment.  They also all shared what was to become the defining feature of PDA ‘an obsessive need to avoid the demands of others’ (E Newson, K Le Maréchal and C David 2003) PDA A Nessessary Distinction

In 2003 the first peer reviewed paper on PDA was published and in this paper Newson proposed that PDA be recognised as a separate sub group within the family of ‘Pervasive Developmental Disorders’ (E Newson, K Le Maréchal and C David 2003) PDA A Nessessary Distinction.  Pervasive Development Disorder (PDD) was the recognised category used at that time by the current classification diagnostic manuals DSMVI and ICD10.  (‘Pathological Demand Avoidance Syndrome – My Daughter is Not Naughty – Foreword and Introduction, Christie 2014).
Since the publication of Newson’s paper terminology has changed and the word Autism Spectrum Disorder/Condition has become synonymous with the term PDD.  The National Autism Plan for Children, also published in 2003, talked about the term ASD /ASC ‘broadly coinciding with the term Pervasive Developmental Disorder’.  The more recently published NICE Guidelines on Autism Spectrum Disorders (2011) described the two terms as being ‘synonymous’.  The importance of this is that PDA is best understood as being part of the autism spectrum, or one of the autism spectrum conditions (‘Pathological Demand Avoidance Syndrome – My Daughter is Not Naughty – Foreword and Introduction, Christie 2014).

Although PDA is not currently specifically described in either of the current diagnostic manuals this does not mean that a clinician cannot diagnose this condition based on their own clinical judgment and expertise.  Indeed many NHS trusts have no specific policy with regard to the diagnosis of PDA and in-fact advocate that their clinicians are free to diagnose PDA based on their own clinical judgment.  This information has being gleaned by Tom Crellin following his request for information regarding the diagnosis of PDA from many NHS trusts via the freedom of information act.  https://www.whatdotheyknow.com/search/Tom%20Crellin/all

Increasingly more and more NHS local authorities are diagnosing PDA and this has become very much a postcode lottery.  Therefore a clinician saying that PDA is not accepted by the NHS as a real and accepted diagnosis is inaccurate because many of them now do diagnose PDA.  It is often down to the individual clinician and is not down to an NHS directive.

Dr Judith Gould http://www.autism.org.uk/Our-services/Diagnosing-complex-needs/About-the-Lorna-Wing-Centre/Our-staff/Dr-Judith-Gould.aspx speaking at the PDA conference in November 2011 emphasised that “Diagnostically the PDA sub-group is recognisable and has implications for management and support” and went on to state at the PDA Conference in Cardiff 2014 that the absence of PDA from a diagnostic manual should not be a sufficient reason for clinicians to not diagnose PDA.

The importance of PDA being highlighted and diagnosed is to better understand the child, what drives the behaviour and to signpost others to the correct and most successful handling strategies for PDA which are often different than those traditionally used for individuals with ASC.  Therefore if a child has the profile as described in the diagnostic criteria for PDA then a diagnosis of ASD whose profile most closely fits that of PDA would be imperative for the long term management and understanding of that individual. This point is emphasised and discussed by Christie (2007) in ‘The Distinctive Clinical and Educational Needs of Children with Pathological Demand Avoidance Syndrome, Guidelines for Good Practice; Good Autism Practice Journal’. Clinical and Educational Needs of children with PDA

The following research helped to establish the differences and the similarities between children who fitted a typical profile of an autism spectrum condition (ASC), children who fitted a typical profile of conduct problems e.g. Oppositional Defiant Disorder (ODD) and those who fitted the Pathological Demand Avoidance (PDA) profile. Although behaviour overlaps were found between the PDA group and the ASC and CP group there were also distinct differences found.

The ‘Extreme Demand Avoidance Questionnaire (EDAQ)’ which resulted from research conducted by O’Nions, E., Christie, P., Gould, J., Viding, E. & Happé, F http://www.ncbi.nlm.nih.gov/pubmed/24117718,  is a screening tool to highlight the possibility of a child having PDA http://www.pdasociety.org.uk/resources/extreme-demand-avoidance-questionnaire

The Disco diagnostic tool, devised by Gould and Wing, has PDA specific questions included to indicate if a child may have ASD sub group PDA rather than a typical presentation of ASC.  less we not forget that Wing introduced the term Asperger Syndrome and was involved in founding the National Autistic Society (NAS) in the UK.

At the Lorna Wing Centre, the Diagnostic Interview for Social and Communication Disorders (DISCO) is used as part of the diagnostic process.

The DISCO has over 500 questions relating to development and untypical behaviours.
Seventeen questions relate to the behaviour described by Professor Newson and her team.
• Unusually quiet and passive in infancy
• Clumsy in gross movements
• Communicates through doll, puppet, toy animal etc
• Lacks awareness of age group, social hierarchy etc
• Rapid inexplicable changes from loving to aggression
• Uses peers as ‘mechanical aids’, bossy and domineering
• Repetitive role play – lives the part, not usual pretence
• Hands seem limp and weak for unwelcome tasks
• Repetitive questioning
• Obsessed with a person, real or fiction
• Blames others for own misdeeds
• Harasses another person – may like or dislike them
• Lack of cooperation, strongly resists
• Difficulties with others, tease, bully, refuse to take turns, makes trouble
• Socially manipulative behaviour to avoid demands
• Socially shocking behaviour with deliberate intent
• Lies, cheats, steals, fantasises, causing distress to others

Leading professionals in the field of Autism appear to be in agreement that the PDA subgroup is definable and that this has implications for the successful management of the child.  Unfortunately many clinicians who are not at the cutting edge of new research and developments are often unaware of recent advances and changes in terminology.  I hope that this post may give you knowledge in order to successfully fight for your child and for him or her to receive the correct diagnosis and management because this is key to the long term prognosis for these children.

Although Asperger’s has being removed from the DSMV it isn’t that the condition has been deleted but simply that the terminology of individuals presenting with an Asperger’s profile has been changed.  However in 1970 this condition or even this profile may not have even existed in diagnostic manuals, does this mean that the condition didn’t exist or merely that it was waiting for diagnostic manuals to catch up with what Hans Asperger’s had already discovered? This is where we are now currently standing with PDA, we are simply waiting for diagnostic manuals and research to catch up with what Professor Elizabeth Newson identified some thirty odd years ago.

During the interim parents, individuals and families will continue to rely on professionals to think outside of the box and to be brave enough to stand up and to be counted.  We need professionals to make judgments based on their own research and clinical expertise and to dare to diagnose what is not currently in a diagnostic manual.  Without these few brave and dedicated professionals we will be dead in the water. Just as Wing and Gould did for Asperger’s and Newson did in her preliminary work towards the acceptance of PDA we now need others to be pioneers and to follow in their footsteps.  Without pioneers and the brave nothing will ever change or move forward in the advancement of understanding Autism Spectrum Conditions!
