Apply the QCAA health inquiry process and the action research approach to investigate a community health priority and recommend evidence-based action

What this dot point is asking

QCAA wants you to use the health inquiry process as your method for investigating a real community health priority and recommending action. Health is an inquiry-based subject, so the process is not background, it is the skill being assessed, especially in the IA1 action research. You need to know the stages, apply them in order, and justify your decisions with evidence. A strong response treats inquiry as a disciplined cycle with feedback, not a one-off report.

The answer

The health inquiry process

The QCAA health inquiry model gives you a structured way to investigate a priority issue. The stages are:

• Recognise and explain. Identify the priority health issue and explain why it matters using data and the determinants of health.
• Analyse and apply. Break the issue down, apply relevant frameworks (determinants, the Ottawa Charter, diffusion of innovations), and analyse the evidence to understand causes and protective factors.
• Plan and evaluate. Design action that is feasible and targeted, then evaluate its likely or actual effectiveness against criteria.

Each stage feeds the next, and you cycle back when new evidence changes your understanding.

Action research

Action research is a cyclical, participatory approach where you plan, act, observe and reflect, then refine and repeat. It is "research with" a community rather than "research on" it, which fits the salutogenic, strengths-based aim of building resilience as a community resource. The cycle has four phases:

• Plan. Identify the issue, set a question, and design an action strategy grounded in evidence.
• Act. Implement the strategy (or a model of it within the scope of school assessment).
• Observe. Gather data on what happened, using surveys, observation or existing population data.
• Reflect. Judge what worked, what did not, and what to change, then loop back into a refined plan.

The cyclical nature is the point: action research expects you to refine based on feedback rather than deliver a single fixed answer.

Evidence, reliability and validity

An inquiry is only as strong as its evidence. You weigh sources for currency, authority and bias. Population data from the Australian Institute of Health and Welfare or Queensland Health is high-authority; a single social-media post is not. You consider reliability (would the same method give the same result again) and validity (does the method actually measure what you claim). Triangulating several sources strengthens your conclusions and is rewarded in the criteria.

Weighing sources for authority and bias

Not all evidence carries equal weight, and the criteria reward students who can justify their source choices. High-authority sources include the Australian Institute of Health and Welfare, Queensland Health, the World Health Organization and peer-reviewed research, because they are produced by expert bodies using rigorous methods and are regularly updated. Lower-authority sources, such as a single blog post, an opinion piece or an advocacy group with a vested interest, may be biased, out of date or unrepresentative. For each source, ask who produced it, when, why, and whether it has been checked. Currency matters because health data changes; authority matters because expertise and method affect accuracy; and bias matters because a source with a commercial or political stake may present a skewed picture. Documenting these judgements, rather than simply citing a source, is what lifts the evidence criterion.

Connecting inquiry to assessment

The IA1 action research instrument assesses exactly this process. You select a priority issue, work through the inquiry stages, design and model an action strategy, and evaluate it through the action research cycle. The recommendations must be evidence-based and feasible, and your evaluation must use clear criteria. Examiners reward a clear question, justified method choices, triangulated evidence, and an evaluation that honestly identifies limitations and next steps in the cycle.
