Consumer health and health information: WACE Year 12 Health Studies Unit 4
“Evaluate the reliability of health information, products and services and explain how health literacy supports informed consumer decisions”
Consumers are surrounded by health information, products and services of very different quality. To decide safely they must evaluate the source, purpose, evidence and currency of information, and recognise how marketing and the media try to influence them. Health literacy, the ability to access, understand, appraise and use health information, is the skill that turns a flood of claims into safe, informed decisions.
What this dot point is asking
WACE wants you to assess the reliability of health information and explain how health literacy protects consumers. A strong answer applies clear criteria to judge a source or product in the stimulus, identifies marketing influences, and links health literacy to better decisions. Marks reward applied evaluation, not a generic list of tips.
Criteria for evaluating health information
Reliable information can be judged against several criteria. Source asks who produced it and whether they have relevant expertise, such as a government health body or a peer-reviewed study. Purpose asks why it was produced, because information designed to sell a product is less trustworthy than information designed to inform. Evidence asks whether claims are supported by research rather than testimonials or opinion. Currency asks whether the information is up to date. Bias asks whether the producer has a commercial or other interest that could distort the message. Applying these criteria to a specific source is what the exam rewards.
Health literacy is the ability to access, understand, appraise and apply health information to make informed decisions about health. It includes finding trustworthy sources, judging their reliability, understanding instructions such as medicine labels, and acting on them. Low health literacy is itself a determinant of poorer health, because people cannot benefit from services and information they cannot navigate.
Evaluating products and services
The same critical approach applies to products and services. For products such as supplements, devices or fad diets, consumers should check whether claims are backed by evidence, whether the product is approved or regulated, and whether the seller stands to profit from exaggerated benefits. For services such as clinics, practitioners or online programs, consumers should check qualifications, registration, accreditation and whether the service is appropriate to their needs. Cost, accessibility and the consumer's rights and avenues for complaint also matter.
How marketing and media influence consumers
Marketing and the media shape consumer decisions, often in ways that work against health. Techniques include emotional appeals, celebrity and influencer endorsement, selective use of statistics, and framing wants as needs. Globalised advertising of unhealthy products is especially powerful. Recognising these techniques is part of health literacy: a critical consumer can see when persuasion is replacing evidence and adjust their decision accordingly.
How health literacy supports decisions
Health literacy ties the topic together. A health-literate consumer can locate trustworthy sources, apply evaluation criteria, see through marketing, understand the information, and act on it safely. Because health literacy is unevenly distributed, improving it is also an equity issue: supporting people with lower literacy through plain-language information and trusted advice reduces a real barrier to good health.
How this maps to the exam
Expect a stimulus presenting a health claim, advertisement, product or service. You may be asked to evaluate its reliability, identify the marketing techniques used, or explain how health literacy would lead to a safer decision. Apply the evaluation criteria directly to the stimulus and name the specific features that make it trustworthy or not.
A consumer-health question gives a claim, advert or product and asks for an evaluation. The marks come from applying named criteria to the specific stimulus, not generic advice.
List the criteria you will apply
Name them up front: source, purpose, evidence, currency and bias. Stating the framework keeps the evaluation systematic.
Apply each criterion to the stimulus
For a website claiming a diet "cures" a chronic disease: source (an anonymous blog with no author credentials, weak), purpose (it links to a paid program, so it sells rather than informs), evidence (testimonials and before-and-after photos, not research), currency (no date), bias (clear commercial interest). Quote the specific features each time.
Reach a justified judgement
Weigh the criteria: an unqualified, undated, profit-driven source using testimonials instead of research is unreliable, so a consumer should not act on it.
Add the safer alternative through health literacy
Conclude that a health-literate consumer would instead check a regulated, independent source (a government health site or a registered practitioner) and recognise the marketing techniques, leading to a safer decision. Applying criteria to the actual stimulus and justifying the verdict is the top-band move.
Students often say a source is or is not reliable without explaining why. The marks come from applying criteria such as source, purpose, evidence, currency and bias to the specific stimulus, then reaching a justified judgement about whether a consumer should act on it.
Exam-style questions
Questions in the style of SCSA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
WACE 2022-style6 marksAn advertisement claims a supplement 'detoxes your body and boosts immunity, as used by top athletes'. Evaluate the reliability of this claim and explain how health literacy would support a safer consumer decision.Show worked answer →
A 6 mark response needs criteria applied to the claim, then the health literacy link.
- Apply the criteria
- Source: an advertiser selling the product, so not independent. Purpose: to sell, not inform, which lowers trust. Evidence: a celebrity-athlete endorsement is a testimonial, not research; "detox" and "boosts immunity" are vague, unmeasurable claims. Bias: clear commercial interest.
- Reach a judgement
- The claim is unreliable: persuasion is replacing evidence, so a consumer should not act on it without independent, peer-reviewed support or regulatory approval.
- Health literacy link
- A health-literate consumer recognises the marketing techniques (endorsement, vague claims), seeks a trustworthy independent source (a government health body or pharmacist), and so avoids wasting money or risking harm.
Markers reward criteria applied to this specific claim, a justified judgement, and a clear health literacy connection.
WACE 2023-style4 marksIdentify two criteria a consumer should use to evaluate the reliability of online health information, and explain why each matters.Show worked answer →
A 4 mark response needs two criteria, each explained.
Source and expertise. Who produced it and are they qualified (for example a government health body or peer-reviewed study)? It matters because an expert, independent source is more likely to be accurate than an anonymous or commercial one.
Purpose and bias. Why was it produced and does the producer profit? It matters because information designed to sell is more likely to exaggerate benefits and omit risks than information designed to inform.
Markers reward two genuine criteria with a clear reason each affects reliability.
