Helen’s story – PDA in families and deciding to home educate
Helen self-identifies with a PDA profile and sees the same traits in other family members including her daughter and her Mum, with mutual understanding across the generations having led to an instinctively collaborative and compassionate approach to both parenting and education. Passionately believing that our education system is not fit for purpose, despite being a highly qualified education professional, Helen has chosen to home-educate her daughter and describes the process as a ‘dance that goes back and forth and a journey of trust’. This is their story …
I discovered PDA at around age 40 and initially dismissed it as yet another attempt to pathologise what I deemed to be pretty ordinary behaviour. I’ve always strongly wanted to avoid every day demands, found other people very confusing, had periods of intense focus, struggled with mood and been really good at playing various roles to get by in the environments I found myself in – I just assumed this was everyone’s experience!
At age 41, I came back to it – by now my daughter had reached compulsory school age and, just as planned since she was 18-months old, she is home-educated. The decision to home educate had nothing to do with [...]
Summary of peer research into PDA by Sally Cat
This blog post covers Sally Cat's motivations for carrying out peer research on PDA, including the evidence and knowledge gaps that she wanted to help fill. It summarises two different pieces of peer research she has conducted:
Her 2016 'Big Traits' study, which took a list of potential PDA traits created by peer suggestions, and tested their prevalence with PDA people and non-PDA autistic people. Analysis (some of which was conducted by Grace Trundle, a PhD student at the University of Nottingham), showed significant differences between these two groups for the majority of the traits, with the PDA group scoring higher in every instance. Sally Cat also disaggregated the results by gender, a process that highlighted some markedly different female and male experiences for some of the traits.
Her 2018 Masking and Social Mimicry peer study, which aimed to investigate the nature of masking for PDA people. Participants included PDA people and non-PDA autistic people, as well as non-autistic people. More than half of participants in the PDA group felt their masking was hardwired and automatic. PDA and non-PDA autistic females were more likely than PDA males to think of their masking as automatic.
Sally Cat concludes by highlighting the [...]

Sleep Misfits: The reality of Delayed Sleep Phase Syndrome & Non-24
Sleep Misfits is the first book to extensively explore delayed sleep phase syndrome (DSPS) and non-24-hour-sleep-wake disorder (Non-24) through the words of actual experients.
Although circadian sleep disorders have seen an increase in published research and media coverage, they are still little-known and little-understood. There remains massive prejudice and discrimination against those of us whose body clocks prevent us from waking and sleeping at socially-approved hours. The main purpose of this book is to tackle these wide-scale negative assumptions by increasing empathy.
Additionally, the book is intended to serve as a manual for people affected, including their families. A detailed section on childhood is included for the many parents confused and exasperated by their children’s wayward sleep hours.
Text book style descriptions are supplemented with research links, and sit alongside comments volunteered by real-life DSPS and Non-24 people, and a wealth of illustrations.
Available on Amazon worldwide as an illustrated paperback, and text-only ebook. The ebook is free to borrow via Kindle Unlimited.

Individual differences, ADHD, Adult Pathological Demand Avoidance and delinquency
Individual differences, ADHD, Adult Pathological Demand Avoidance and delinquency
In this paper, Egan et al looked at a range of different characteristics of a group of adults to analyse how PDA might fit with other described conditions. They used the EDA-Q developed in their previous work as a self-report tool for adults (EDA-QA; Egan et al 2018) and invited adults who identified themselves as having PDA to complete it and a number of other surveys including personality traits. As a forensic psychology department, they were interested to learn more about the construct and how it might relate to the potential for criminal behaviour, or ‘delinquency’.
The results showed that for community adult populations, self-reported individual differences in ADHD, emotional instability, and antagonism appear to better predict the PDA than ASD. They went on to suggest that the association PDA has with delinquency may reflect these constructs, which are also correlates of offending.
The results are interesting and appear to be a challenge to clinical experience. The EDA-Q is known to capture those who are extremely demand avoidant for a range of reasons, so to repeat this work within a clinical cohort would be a useful next step.

Jim’s story
Jim is a 33 year old PDAer and has worked at Waitrose for 7 years. He likes to raise awareness of PDA and share his story so that parents know that things can turn out well for their child despite how challenging circumstances may be along the way. Jim also shares details of his time at school, masking, developing the skills to live independently and his love of writing and driving.
I’ve been working at Waitrose for seven years. It was my Mum who suggested I apply for the job originally because Waitrose is known for being inclusive and taking care of its staff, and because the store where I work is local to me. I worked my way up, starting with a few hours on a Saturday, then taking on some evening shifts. When a full-time worker left, my manager was delighted for me to take over the role. To feel valued and be called a ‘key player’ at work is really special.
People wonder how I cope with being told what to do. I do still have a bit of a feeling inside when I’m told to do things, but I’m very meticulous and pre-prepare things to make sure [...]

Pets and PDA
For some people, owning a pet greatly improves both their mental and physical wellbeing - research shows interacting with animals reduces blood pressure, lessens anxiety and improves social interactions.
Many autistic individuals and their families find pet ownership particularly beneficial. A study by Lincoln University, for instance, found that autistic children experienced fewer meltdowns, and their parents felt less stressed, if a dog was nearby. For others, however, pet ownership comes with too many challenges.
As with all things, there’s no ‘one size fits all’ approach.

Local position statements on PDA
Local authorities, NHS trusts and other bodies are increasingly producing and sharing information about PDA within local areas. This page contains links to such information.
Local position statements
Some local areas have found it helpful to state their position on the use of terminology around PDA.
Examples of formal position statements include:
Surrey
East Sussex
Alder Hey Children's NHS Foundation Trust
Examples of PDA being acknowledged include:
Rotherham, Doncaster and South Humber NHS Foundation Trust – CAMHS
Northamptonshire Heathcare NHS Foundation Trust
These position statements and acknowledgements of PDA clearly illustrate how it is possible for local authorities, and supporting organisations, to acknowledge and flag up the PDA profile in diagnosis reports, as a signpost to appropriate support, whilst still working within the guidelines of the DSM-5-TR and ICD-10 diagnostic manuals.
As has been the case with Alder Hey Children's Hospital, it is hoped that local authorities who do accept the validity of the PDA profile of autism, will invest in commissioning PDA specific training to improve outcomes for PDA individuals.
The PDA Society feels this is a very positive step in the right direction for greater understanding, awareness and acceptance of the PDA profile, and hope that both children and adult services in other local [...]

Transition to adulthood
When we think about transitions we naturally think about the big transitions like leaving school or transferring from primary to secondary school. But transitions of any kind, at any time, may be difficult for PDA individuals. Starting a new club or activity, leaving home in the morning to go to school or work, even moving from their bedroom to the kitchen, can be extremely difficult for some. Transitions are a demand.
This page focuses on transitions to adulthood, i.e. beyond age 16.
It’s good practice for schools to start thinking about transition for SEND children from year 9 (age 14). For children with an EHCP, this will start at the Y9 annual review and a Transitions Team Social Work should be invited to attend alongside the parents, school, local authority and any other relevant professionals involved with a child.
The options for post 16 are:
Sixth form
College

Work – please see our workplace adjustments for PDA page and this Transition to employment toolkit by Ambitious about Autism

Helpful approaches infographic: PANDA approaches
This infographic illustrates the key approaches which are helpful in working with, understanding and supporting an PDA person.
Conventional support strategies, including those often recommended for autism, are often ineffective and counter-productive with a PDA profile of autism.
In place of structure, routine, firm boundaries, praise, rewards/consequences, is a person-centred approach based on negotiation, collaboration and flexibility.
The PDA Panda symbolises the need to tailor the environment to meet needs and the P-A-N-D-A mnemonic is a simple reminder of helpful approaches.

Tim’s Top Tips: ideas for adults
Tim Collins is an adult who was recently diagnosed with PDA. Along with sharing his story with us (please see his case study) he has kindly created a list of Top Tips designed to help adults navigate their way through life.
Daily life
Keep a notepad and pencil handy at all times to jot down your thoughts. This reduces the pressure to remember everything and you can review your ideas at a time to suit you.
Make a daily list of tasks then categorise them as important (e.g. making appointments or shopping) or ‘nice to have’ (non-essentials such as baking a cake or taking the dog for an extra walk).
Select only three tasks from the list that you will carry out and cross the rest out. If there are too many important tasks to carry out then the ‘nice to have’ items can be saved for another day.
Make time for ‘normalising activities’ which allow you to de-stress and empty your personal ‘capability tank’. I like to listen to music, go for a peaceful walk or cycle and even vacuum the house! Schedule gaps between meetings at work to allow for this mental re-charging time.
Practice mindfulness- I prioritise [...]

Adults: PDA & mental health
The following is a summary of Dr Judy Eaton's talk at the PDA Society Conference in Birmingham on 18th April 2018
Judy opened by sayings that people often ask her “what is this PDA? There was never this PDA when we were younger. Where were all these people?”. Her response is that actually they have always been there, and that she has found it both interesting and a privilege to talk to adults with PDA about their experiences.
Introduction
Judy shared a case study to highlight the need for early understanding of PDA and the urgent need to educate other professionals about the condition, particularly those working in adult services:
James, a 41 year old man whose parents now feel PDA accurately describes, had received a diagnosis of autism as a child. Since leaving his specialist residential school for children with autism, where he was bullied, assaulted and was very unhappy, he has been sent to two different prisons and 7 different secure hospitals. He was placed under section 37 of the Mental Health Act, and subsequently detained under section 3 of the Mental Health Act with other patients who required very different management regimes to him. He was often very vulnerable and [...]
