BUT NOT NECESSARILY FOR THOSE WITH A PDA PROFILE!
8 Information about Pathological Demand Avoidance
I am a third party approved provider of PDA training by the PDA society. Please get in touch if you’d like me to deliver a session for your school
PDA is now more recognised as a distinct profile of autism. Individuals with a PDA/EDA (alternative terminology: Extreme Demand Avoidance) profile will share similar difficulties to others on the autism spectrum (triad and sensory). In addition, the central difficulty for people with PDA is their “anxiety-driven need to be in control and avoid other people’s demands and expectations.” Understanding PDA in Children. Christie, Duncan, Fidler & Healy (2011). It is the Autism which underpins the extreme demand avoidance and need for control. Because PDA is not currently included in either of the diagnostic manuals (DSMV and the ICD11), the validity of this profile of ASD remains a contentious subject among some professionals.
Features of PDA …
-
Resisting and avoiding the ordinary demands of life – getting up, joining family meal, even when it’s what the person wants to do.
-
Use social strategies as part of the avoidance.
-
Compliance on ‘their terms’.
-
Appearing sociable on the surface.
-
Excessive mood swings and impulsivity.
-
Lack of constraint by social norms or sense of hierarchy.
-
Comfortable in role play – reality and pretence merge and blur.
-
Threats or extreme behaviour.
-
Lack of sense of responsibility or sensitivity to others’ distress.
-
Failure to constrain behaviour in public.
-
Obsessive behaviour – often social in nature.
What this might look like …
-
Can be controlling and dominating, especially when anxious and are not in control of their environment.
-
Can also be very affectionate, charming, sociable and chatty, when they are calm and feel safe. This conflicting and variable presentation is confusing for parents and professionals alike.
-
Sometimes a child with PDA can appear very anxious at home but remain relatively passive at school (masking).
-
Demands at school can lead to severe ‘meltdown’.
-
Some children can experience such high anxiety in school that they become school refusers.
-
Just as with ASD -> experience over or under-sensitivity in any, or all, of their senses: sight, smell, taste, touch, hearing, vestibular, proprioception or interoception.
-
Seen in people of both genders and in equal proportions. No prevalence rates for PDA yet. As more diagnoses of PDA are made, prevalence figures will become more apparent.

Information and Advice from two inspirational practitioners. In this PDA Society webinar Phil Christie and Ruth Fidler from Autism Associates provide an overview of the education and support needs of children with the PDA profile. They outline how some of the strategies that are typically found to be effective for autistic children and young people (such as the use of routine, predictability and structure) need considerable adaptation, as PDA individuals respond better to less direct and more collaborative approaches.
♥From the PDA Society, an 8 minute video which gives real life insight into PDA.
Some starting points for school staff:
-
Quality of relationship is key. The opposite of anxiety isn’t calm … it’s trust.
-
Identify a quiet space (with child/young person if appropriate).
-
Show respect – kids should know you like them unconditionally.
-
Build in flexibility and choices to timetables – sense of autonomy. Balance – 2 options – offer to whole class?
-
Think ahead/plan for change. Give child advanced warning.
-
Work with special interests. Their special interest is your most valuable tool.
-
Keep calm! PDA kids are adept at reading reactions -> your reaction may motivate!
-
Be willing to apologise. No relationship – no progress.
-
As few ground rules as possible – pass over responsibility ‘I’m sorry it’s health and safety’ or ‘It’s on the timetable I’m afraid’.
-
Use complex language? Can sound more like negotiating and may intrigue.
-
Humour can help.
-
Monitor stress levels – scale back demands if necessary.
-
Declarative language. ‘I wonder if we can …?’ ‘Maybe we could investigate …?’ etc.
-
Use distraction.
-
Ask for advice!

1 What do we mean by unstructured times, why are these times so difficult for autistic children/young people and strategies to support?
Break time, playtime, lunchtime, ‘wet’ playtime, social events can be difficult and stressful for children/young people with autism. They often require support during these times – often more than in the classroom.
♥Advice from the National Autistic Society.
♥Very sensible advice from Reachout ASC.
♥Playtime/break times create excellent opportunities for staff to teach interaction skills. Wee bit out-of-date but still some good, sound advice.
Some general advice for adults supporting children at break times.
-
Plan, teach and model social skills.
-
Encourage positive relationships you notice developing.
-
Identify for the child/young person who they can go to if they need help.
-
Teach the difference between joking and teasing. Some visuals to support those unwritten social ‘rules’ …
-
Allow child/young person ‘time out’ to be on their own – recharge batteries.
-
When playtime/break is over – cool down or relaxation activity if stressful time.
-
Break playtime/break/lunchtime up – schedule/checklist of ‘things to do’. (see below)
-
Cards with ideas of things to do in the playground/at break. (see below)
-
Allow access to ‘special interest’ clubs.
-
Let them be a helper in the playground.
-
Give them a job to do.
-
Let them be a buddy to a younger child/young person – careful explanation.
-
Access to quiet zone in playground – possibly with structured activities.
Sometimes children need a ‘timetable’ for the playground to give them some structure and predictability. Here are a couple of examples I’ve used in the past.
The child chose a different strip for each day of the week and was supported by an adult to move from one activity to the other. Eventually, they dispensed with the visuals as they had build up a framework of activities they could do at break time.

Sometimes, teaching them some ‘openers’ can be helpful. It might be necessary to practise these with a trusted adult before asking peers.
2 Supporting children/young people when things go awry
♥Visuals to support communication when they have had a tricky time. It’s a great way of solving playground/break time issues visually, making the discussion permanent. You are then able to return to the ‘conversation’ at a later date if necessary.

3 Supporting Transitions
Transition is another word for change and change is something different. Yet another potentially/perceived unstructured time for learners. Transition and change are potential stressors – at home, school and in the community. Autistic children and young people can find any kind of transition very difficult. Some examples of transition are:
-
Daily transitions – home to school, one activity to another, a different teacher, pizza instead of chips, different areas of the house/school, change in people at home/community
-
Changes at home – new baby, moving house, bereavement, holiday, making/changing friends, divorce or separation, Parent/carer new job may involve working away from home or new shift patterns
-
Stepfamilies and all the changes that come with transitioning to a new family.
-
Class to class – e.g. P3 -> P4
-
Education: home -> nursery, nursery -> primary, primary -> secondary, secondary -> workplace/college/university
-
Personal transitions – ‘growing up’ which can be a tricky transition even for typically thinking youngsters.
Most of us intuitively understand how to deal with these life changes, however, transition/change often causes significant anxiety (the overarching emotion of autism) for those on the spectrum and they often need a great deal of support to make a transition. It’s not always major transitions/change which can cause most anxiety. We must remember that what we perceive to be a small transition (and therefore shouldn’t cause stress and anxiety) may not be perceived that way by the autistic child/young person and may cause huge stress and anxiety.
You can support transitions by remembering The 3 P’s …
-
Plan (visuals are often useful)
-
Prepare (visuals are often useful)
-
Practise (when they are calm)
NO surprises!
Visuals which can be useful in supporting transitions:
-
Calendar/diary
-
‘to do’ list – photos, symbols, text
-
First (now), then (next) boards
-
Timetables
-
Photographs (people and places)
-
Social stories/comic strip conversations
-
Transitions booklets, One Page Profile, Communication Passport
-
Timers – watch, sand, clock, tech

Advice from The Autism Toolbox:
Primary to Secondary School
The transition from Primary to Secondary School is a major change in a young person’s life but can be even more challenging for autistic learners. It involves a large number of changes which may include:
-
Dealing with a much larger number of pupils
-
Dealing with an increase in the number of classes and subjects
-
Different travel arrangement to get to and from school
-
Being the youngest at the new school
-
More teachers and their different approaches
-
A new and often much larger building
-
New timetables
-
New and different routines
-
Coping with subjects they have not encountered before
-
A longer working day, taking into account travel time.
Supporting transitions for autistic children into Secondary School
-
Families and autistic learners should play a key role in this transition. They should be part of the planning process and transition meetings and may participate in an enhanced transition programme with the secondary school
-
Enhanced transition might involve extra visits to the secondary school. It can help some learners to have a task/project to do during the visit e.g. checking the temperature in key places
-
In line with legislation, transitions should be planned well in advance: this may mean the first formal planning meeting with the secondary school could take place in Primary 6
-
It is crucial that all agencies work together to ensure a smooth transition for the autistic learner
-
It is important that staff in secondary schools are made aware of autistic learners and access their learner profiles
-
The lead professional in the transition process should draw up a transition plan detailing learner strengths and areas where additional support may be required. This should also include any sensory issues experienced by the learner
-
Ensure that the transition plan is appropriately broken down into small, manageable steps if needed
-
Write a social story about transitioning from school to school. Highlight the big changes that may cause anxiety such as waking up earlier, taking the bus, or eating lunch at school rather than at home.

♥It’s so easy to edit this primary to secondary transition workbook. I’ve used it again and again over the years.
♥A free primary to secondary booklet from TES. Some of it may not be specific enough for autistic young people but still has some useful stuff. I’d certainly colour code the sample timetable.
