How developmental history is gathered

Parents may have died, live far away, remember little, or be people you do not want involved. School records may no longer exist. You can tell the assessment service this without first repairing a relationship or locating every document. Start by asking what they require and how they approach gaps in the history.

An adult assessment considers experiences across life as well as current functioning. Autism CRC’s adult guidance describes assessment as a process of understanding a person’s development, health, daily life and support needs. [1] It is broader than completing a questionnaire or reproducing a childhood checklist.

In a discussion, you might describe friendships, play, routines, strong interests, communication or sensory experiences across different ages. Use memories you actually have. ‘I cannot remember’ is useful information too. A clinician can ask follow-up questions without expecting you to reconstruct exact dates or turn every childhood experience into an autism example.

The adult autism and AuDHD assessment process guide explains where developmental history sits within the wider assessment.

What other information may help

NICE recommends involving someone who knows the person or using documentary evidence where possible. [2] Depending on what is available and appropriate, that could include an older sibling, another relative, a longstanding friend, old school comments or previous health records. Each source contributes a different view.

A partner who met you in adulthood can describe current life, but usually cannot provide firsthand childhood observations. A sibling may remember shared routines without knowing what school felt like for you. It helps to identify how the person knows you and which period they can describe.

You can bring brief notes organised by life stage, marking what you remember directly, what someone told you and what remains uncertain. Include experiences that do not fit your initial explanation as well as those that do. The purpose is to understand the pattern accurately, rather than assemble a case for a predetermined result.

If you are concerned that your effort may be hard to see during the appointment, our article on masking during autism assessment suggests ways to discuss that experience.

What missing information means for the conclusion

Autism diagnostic criteria include features present during the early developmental period. Some features may become more apparent when demands increase or may have been covered by learned strategies. Missing paperwork does not remove that developmental requirement. [3]

The clinician weighs the available information, its consistency and its limits. Sometimes there is enough evidence for a conclusion without a parent interview. In other situations, further information or another assessment perspective may be needed. Different services and tools also have different requirements, so ask before committing to the process.

Ask how uncertainty will be explained

A useful feedback discussion should explain the reasoning, any unresolved questions and the next practical options. It should also make space for support needs, whether or not a diagnosis is established. Ask what will appear in the report and which questions the assessment can realistically answer.
