A health official argues that a new public health campaign promoting daily fruit and vegetable consumption will significantly reduce the incidence of chronic diseases in the city. The campaign focuses on educational materials and public service announcements. Which of the following, if true, would most seriously undermine the effectiveness of this campaign?
- AChronic diseases are also strongly linked to genetic predispositions and lack of physical activity.
- BMany residents in low-income areas have limited access to affordable fresh fruits and vegetables.
- CThe educational materials are written at a reading level too high for a significant portion of the target audience.
- DPrevious public health campaigns on other topics have had mixed results in the city.
Show answer & explanationAnswer & explanation
Correct answer: B. Many residents in low-income areas have limited access to affordable fresh fruits and vegetables.
The campaign assumes that providing information will lead to behavioral change and improved health. Option A highlights a critical barrier: even if people are educated and motivated, a lack of access to affordable produce prevents them from acting on the advice. This directly undermines the campaign's effectiveness despite its educational efforts.
Why the other options are wrong
- A. While true, this points to other contributing factors but doesn't negate the potential effectiveness of improved diet, assuming access.
- C. While a flaw in the campaign's *design*, it doesn't represent an external barrier like access; rather, it suggests the campaign itself needs improvement, but doesn't undermine the *potential* for the advice to be followed if understood and accessible.
- D. Past performance is not necessarily indicative of future results for a different campaign, and 'mixed results' is vague.
Undermining Campaign Effectiveness
To undermine the effectiveness of a campaign means to introduce information that shows the campaign's objectives are unlikely to be met due to external barriers, flawed assumptions about the target audience, or inherent limitations.
- Focuses on the practical outcome of an initiative.
- Often highlights an unaddressed obstacle or constraint.
- Challenges the feasibility of success despite good intentions.
Memory trick: Even with a clear target, a hidden barrier can stop the arrow.
