7.1 Audience Analysis and Segmentation

Where Area VI sits on the exam

The CHES exam is built on the Health Education Specialist Practice Analysis II (HESPA II 2020) Eight Areas of Responsibility. The test delivers 165 items (150 scored, 15 unscored pilot items) in a 3-hour window, and a candidate passes with a scaled score of 600 on a 200-800 scale. Area VI: Communication is weighted 12%, which is roughly 18 scored questions. That is the same share as Area I (Assessment), so communication is heavily tested and worth deliberate study.

Items in this area usually describe a population, a health issue, and several candidate messages or channels. The strongest choice is rarely the flashiest one; it is the option that fits the intended audience and rests on data.

Priority population vs. priority audience

Start by separating two terms the exam loves to blur. The priority population is the group affected by the health issue. The priority audience is the specific group a given message is designed to move. They overlap but are not identical.

Consider a program to reduce childhood asthma triggers in public housing. Children are the priority population, but the messages may target several priority audiences:

What makes a segment useful

Segmentation divides a broad audience into smaller groups that share relevant traits. CHES-level segments should be practical: age, language preference, reading comfort, cultural identity, stage of readiness to change, perceived risk, trusted messengers, barriers, preferred media, geography, or decision role. A segment earns its place only when it changes the strategy.

Avoid convenient-but-meaningless splits. Dividing a county by ZIP code helps with mailing logistics but does not explain beliefs or barriers. Splitting by age matters for a vaccination push only if younger and older adults differ in channels and concerns. Exam items often test whether you pick variables that actually explain communication needs.

Building the audience profile

A useful profile blends quantitative and qualitative input. Surveys show which barriers are most common. Focus groups reveal wording that feels respectful or confusing. Key-informant interviews name trusted messengers. Clinic data show who misses appointments. Social-media analytics show where engagement happens but never replace direct input from affected people.

A strong profile answers: what the audience already knows, what they misunderstand, what action is requested, which benefits matter, which barriers interfere, who influences them, and how they prefer to receive information. That profile then drives framing, reading level, language access, visuals, and channel mix.

Beware stereotypes. Cultural tailoring comes from community input and credible data, not assumptions; two people who share a language can differ in beliefs, trust, access, and family decision roles. Use cultural humility: ask, involve representatives, and pretest before broad release.

Access is part of fit

A text reminder works for people with stable phones and data, yet fails for those who share phones, change numbers, or need print. A web video engages only if captions, transcripts, mobile display, and low-bandwidth options exist. In scenarios, follow the sequence: define the objective, define the audience, review literacy/culture/barriers/benefits/channels, then draft and pretest. Jumping straight to a brochure or app skips the analysis that makes communication ethical and effective.

Common trap: an option that picks a channel because it is popular or modern, before the objective and audience are defined, is almost always wrong.

Worked scenario: a flu campaign

A county wants to raise flu vaccination among working adults aged 18-49. Assessment shows the population is 40% Spanish-preferring, most work hourly jobs with limited daytime flexibility, and many already intend to vaccinate but cite inconvenient clinic hours. Walk through the analysis: the communication objective is to convert intention into a scheduled visit. The priority audiences split by readiness and language, so the program builds a Spanish-language and an English-language track. The barrier is time and hours, not awareness, so a long educational brochure would miss the point.

The channel must reach phones during off-hours, so evening text reminders with a Saturday clinic time and a one-tap scheduling link fit better than a daytime radio ad. Trusted messengers include employers and a local community clinic rather than a distant agency. This is the sequence the exam rewards: objective first, audience second, barrier and benefit third, then channel and messenger.

Readiness and tailoring

The Transtheoretical Model stages of change (precontemplation, contemplation, preparation, action, maintenance) are a practical lens for segmentation because each stage needs different communication. Someone in precontemplation needs a relevant benefit and a reason the issue applies to them; someone in preparation needs a removed barrier and a specific call to action. Tailoring (one-to-one customized messages based on individual data) differs from targeting (messages for a defined segment); both outperform a single generic message but require different data and resources.

On the exam, when a stem describes people who already intend to act, the best answer addresses logistics and prompts, not basic awareness.

Finally, document the rationale. A defensible audience analysis ties each communication choice to an assessment finding, which is also what reviewers, funders, and the exam expect you to be able to justify.
