Could PDA help explain
what you’re seeing?
It may be one framework to explore. Start with the experience, and leave room for more than one explanation.
PDA is used to describe a pattern of pronounced demand avoidance, often discussed in relation to autism. Definitions, mechanisms, and its diagnostic status remain debated. Your family can describe difficulties and ask for support without a questionnaire settling the label.
What the EDA-8 measures
The EDA-8 is an eight-item caregiver-report research measure. Its development study used data on autistic children aged 5–17. It describes reported demand-avoidant traits; it does not establish why they occur, diagnose PDA, or rule it out.
The total ranges from 0–24. There is no validated clinical cutoff. The research describes reduced precision above 19, not a boundary between children who do and do not have PDA.
Porchlight does not administer or score the EDA-8. It links to the published research and the PDA Society’s measure information. An embedded version would need verified wording, instructions, reuse terms, population limits, and clinical review.
What else deserves attention?
Communication and task demands, sensory surroundings, worry, difficulty starting or switching, pain, sleep, and changes in daily life may all be relevant. These can overlap. This website cannot sort them into diagnoses. A concrete example and its context are useful things to bring to an individual assessment.
New or worsening difficulties, pain, or disruption to eating, drinking, sleep, or safety deserve professional attention. In immediate danger or serious injury, contact local emergency services; this site is not monitored for urgent support.
Support is not a score you have to earn.
