SPTH2101 Chap.5 Case History and Converging Evidence
Case History and Converging Evidence
Case history is useful when it changes sampling, interpretation, access, referral or management. The University forms cover family and cultural context, languages, hearing, birth and development, feeding, speech and language history, motor and medical information, current communication concerns, strengths and interests. Those categories should not be turned into causal stories automatically.
A history of ear problems can justify hearing clarification; it does not prove the cause of a speech pattern. Familiar and unfamiliar listeners may report different intelligibility because their contexts differ. Converging evidence therefore compares caregiver and teacher report, case history, direct observation, OMA, word tasks and connected speech. Agreement raises confidence, while mismatch directs the next sample.
Ethical reasoning also matters: sensitive personal information is collected for a purpose, reported with restraint and never reproduced in study examples.

Key terms
- Case history
- Contextual record of development, language, hearing, health, participation, strengths and concerns used to plan assessment.
- Caregiver report
- Family-provided evidence about communication over time and across familiar activities and listeners.
- Teacher report

- Converging evidence
- A reasoned comparison of multiple evidence sources, including informative agreement and mismatch.
- Functional concern
- A communication difficulty described through its effect on activities, participation or listener understanding.
Case History and Converging Evidence FAQ
What makes a case-history question clinically useful?
It should change the assessment question, sample, interpretation, access support, referral consideration or management plan. Asking for information without knowing how it will be used creates volume but not reasoning. State the consequence of each relevant answer.
What should I do when reports conflict?
Treat the mismatch as information. Identify the different listeners, activities, settings and time periods, then design a sample that changes one important condition. Conflicting reports can reveal a context effect rather than an unreliable informant.
How should sensitive details appear in an exam answer?
Discuss relevant categories and clinical consequences without reproducing names, contacts or identifying records. Show how consent, recording and confidentiality affect data collection. Personal detail should never be included merely to make a case sound realistic.
How does a history clue become an assessment action?
Write an explicit if-then link. Identify who reported the clue, the context and the uncertainty it creates; then name the sample, access support, clarification or referral consideration it justifies. State what different results would change. A hearing history can prompt current clarification without proving cause, and multilingual use can expand sampling without making English the norm.
This form keeps relevant background information connected to decisions while exposing any leap from association to explanation.
Exam move
Build if-then links from common history categories. If several languages are used, then plan representative language samples. If listeners disagree, then compare contexts. If hearing information is old or uncertain, then clarify it without claiming causation. If an interest supports engagement, then use it to elicit a representative sample.
Practise ending each case with one sentence that explains how the assessment answered the original concern and one sentence that identifies what remains uncertain. Make a purpose table for languages and culture, family history, hearing, pregnancy and birth, feeding, development, medical information, earlier services, current concern, strengths and interests.
Beside each category, write the assessment decision it could legitimately change. Cross out any detail that tempts a causal explanation but does not alter sampling, interpretation, participation, referral or risk management. Practise neutral follow-up wording by asking for examples of both successful and difficult communication.
When two reporters disagree, preserve the source, setting, listener familiarity and time period rather than averaging the accounts. Design a comparison that changes only one important condition, such as noise, language, task type or listener. Before proposing that comparison, state how each possible result would affect the next decision.
Include a confidentiality audit: identify which information is necessary for the answer, replace identifying detail with a category and note when consent or recording conditions matter. Finally, return to the original concern after analysing the samples. Explain which evidence converged, which evidence remained mismatched, which strength can support management and what monitoring or referral is justified.
A strong revision card should therefore connect history clue to assessment consequence, not history clue to assumed cause.
