The county, its draft poster, focus group comments and communication plan are composites written for a model paper; state data and research findings come from the sources cited.

The county health department's communications team had a poster ready for the printer: a black background, a single pill and three words, "One pill can kill." It would go up in schools, bars, bus shelters and clinics. Before approving it, the director asked the team to test it against communication theory and evidence. This paper applies that test.

Why the Message Matters

The threat is real. CDC's provisional counts show drug overdose deaths in Colorado rose from 1,100 in 2019 to 1,917 in 2021 and stood at 1,819 in 2025; fentanyl-class deaths, which CDC codes as synthetic opioids excluding methadone, quadrupled from 251 to 1,044 between those years, while methamphetamine and other stimulant deaths climbed from 367 to 879 (Centers for Disease Control and Prevention [CDC], 2026). A poorly designed message would waste one of the department's few chances to reach people at risk.

The Extended Parallel Process Model

The extended parallel process model proposes that people appraise a fear message twice: first for threat, how serious and likely the danger is, and then for efficacy: will the advised step actually protect them, and are they capable of taking it? If the danger feels real and the remedy feels workable, people act to reduce the danger. A frightening message that offers no workable remedy tends to backfire in a quieter way: people manage the fear rather than the danger, by denying it, looking away or dismissing the source (Witte, 1992).

The Poster Through the Model

The poster raised threat but offered no action, a pattern familiar from earlier drug campaigns: nothing about testing drugs, carrying naloxone, not using alone or calling for help. Under the model, a high-threat, no-efficacy message risks fear control, especially among people who already use drugs and cannot simply stop. A warning without a way out asks people to be afraid and then leaves them there.

What the Evidence Says About Fear

Fear appeals are debated, but evidence is substantial. A meta-analysis of 127 articles with 248 independent samples and more than 27,000 participants found that fear appeals had a positive effect on attitudes, intentions and behaviors, with an average effect size of 0.29, and were more effective when messages included efficacy statements, depicted high susceptibility and severity and recommended one-time rather than repeated behaviors; the authors found no circumstances in which fear appeals backfired (Tannenbaum et al., 2015).

Reading the Evidence Together

The two sources agree on the practical lesson: fear can motivate, but it works best paired with specific, doable actions. One-time actions, such as picking up a naloxone kit, fit the meta-analysis's finding better than repeated ones, such as always testing drugs, though both matter.

Social Marketing

Social marketing applies marketing concepts to health: the product, what the audience is asked to do; the price, what it costs them in effort, money or social risk; the place, where they can act; and the promotion, how the message reaches them. The poster promoted nothing an audience could obtain. A revised campaign would offer a product, free naloxone and test strips, at low price and convenient places.

Framing

Framing shapes how audiences understand a problem's causes and solutions. The poster framed overdose as a matter of individual danger from a single bad choice. A public health frame would present overdose as preventable, with community tools such as naloxone and treatment.

Diffusion of Innovations

Diffusion theory explains how new practices spread through social networks, starting with innovators and early adopters. Carrying naloxone is an innovation for many families; peers, bartenders and pharmacists who already carry it can model the practice.

Campaigns Need Services Behind Them

A review of mass media campaigns across tobacco, alcohol, drugs, heart disease, road safety and other behaviors concluded that campaigns can produce positive changes or prevent negative ones across large populations, with outcomes depending on the concurrent availability of required services and products, community programs and supportive policies, and called for longer, better-funded campaigns to achieve adequate exposure (Wakefield et al., 2010).

What the Focus Groups Said

The team showed the poster to three small groups. Parents found it frightening but did not know what to do. Young adults said it looked like the "just say no" ads they ignored. People in recovery at a peer center said it made them feel judged and did not mention naloxone, which had saved two of them.

Stigma and Word Choice

Focus group participants in recovery objected to words such as addict and abuser in the department's companion materials. Language shapes how audiences judge people who use drugs and whether those people believe a message is meant for them. The revised materials use person-first terms, such as people who use drugs, and avoid images of needles or dark alleys that signal danger from other people rather than protection for oneself and one's friends.

Channels and Timing

Posters alone reach few people at the right moment. The campaign adds text alerts when a local batch of contaminated drugs is detected, messages on bar coasters and in restroom stalls, radio spots in English and Spanish and short videos on social media featuring local people who carry naloxone. Timing matters too: alerts reach people when risk is highest, and restroom messages reach them where overdoses often happen.

The Revised Message

The revised poster keeps a clear threat but adds efficacy: "Fentanyl is in pills and powders. Carry naloxone. Never use alone. Free kits here." A QR code and text line point to the nearest free naloxone and test strips. Versions for parents, young adults and bar staff use different images and messengers.

Theory Behind Each Change

The threat line maintains perceived severity and susceptibility. The three actions raise response efficacy and self-efficacy. The free kit offers a product at low price and a nearby place. Messengers from each audience support diffusion. The public health frame replaces blame with tools.

Measuring Theory Constructs in Pretests

Pretests will measure the model's constructs directly. After viewing each version, participants will rate how serious and likely they think the danger is, how well carrying naloxone would protect someone and how confident they are that they could get and use a kit. A message that raises threat without raising these efficacy ratings will be revised before printing.

Limits

Theory guides but does not guarantee results. The revised messages will be pretested with each audience before printing, and exposure and naloxone pickup will be tracked.

Conclusion

The draft poster would have raised fear without offering a way out. The extended parallel process model predicts such messages lead to avoidance, and meta-analytic evidence shows fear works best with efficacy statements. Social marketing, framing and diffusion add product, frame and messengers, and a review of campaigns shows that messages must have services behind them. The revised poster pairs threat with action and points people to free naloxone.
