Short answer

Design interfaces for online health information to actively guide users towards credible sources and prompt critical evaluation, rather than assuming users will perform these checks themselves.

Field: User-Centred Design
Source: BMJ (2002)
Method: Qualitative study combining focus groups, usability testing, and in-depth interviews.
Sample: 48 participants (21 in focus groups, 17 in usability testing/interviews)
Evidence: Moderate effect

Consumers often fail to critically evaluate the source and credibility of online health information, prioritizing ease of use and professional appearance over substantive checks. This user-centred design research insight is drawn from a 2002 study published in BMJ. Using Qualitative study combining focus groups, usability testing, and in-depth interviews. with 48 participants (21 in focus groups, 17 in usability testing/interviews), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design interfaces for online health information to actively guide users towards credible sources and prompt critical evaluation, rather than assuming users will perform these checks themselves.

Users Overlook Credibility Cues When Searching for Online Health Information

Consumers often fail to critically evaluate the source and credibility of online health information, prioritizing ease of use and professional appearance over substantive checks.

BMJ · 2002

Key Findings

01Users found health information relatively quickly, but their search techniques were often suboptimal.
02When assessing credibility, users mentioned looking for source, professional design, scientific/official tone, language, and ease of use.
03During actual searches, users did not check 'about us' sections, disclaimers, or disclosure statements.
04Many users did not remember the specific websites they retrieved information from.

Application

Design takeaway

Design interfaces for online health information to actively guide users towards credible sources and prompt critical evaluation, rather than assuming users will perform these checks themselves.

How to apply

When designing any platform that presents health information, integrate clear visual cues for source authority (e.g., recognized institutions, peer-reviewed journals) and consider interactive elements that prompt users to consider the information's origin and evidence.

Project actions

01Consider how users will actually interact with your design, not just what they say they will do.
02Think about how to make important information (like source credibility) unmissable.

Method & Evidence

AimTo understand how consumers search for and appraise health information on the internet.

MethodQualitative study combining focus groups, usability testing, and in-depth interviews.

ProcedureParticipants engaged in focus group discussions, were observed performing web searches for health information in a lab setting, and were subsequently interviewed about their search and appraisal strategies.

Sample48 participants (21 in focus groups, 17 in usability testing/interviews)

ContextOnline health information seeking

Variables

IVType of information sought, user's prior knowledge (implied)

DVSearch time, number of websites visited, user-reported credibility appraisal methods, actual credibility appraisal actions (e.g., checking 'about us').

CVUsability lab setting, specific health questions provided.

Strengths & Limitations

Strengths

+Combines multiple qualitative methods for a richer understanding.
+Observational data provides insight into actual behaviour, not just self-reported intentions.

Limitations

The findings might not apply to all demographics or all types of online information. The specific websites and search queries used in the study might influence results.

Reliability & validity

The use of multiple qualitative methods (focus groups, observation, interviews) enhances the validity of the findings by triangulating data. Reliability is supported by detailed descriptions of procedures and findings, allowing for potential replication of the qualitative analysis.

Think critically

To what extent has the evolution of the internet and user digital literacy since 2002 changed these findings regarding online health information appraisal?

Design Principles

"Proactive credibility signalling: Design systems that make trustworthy information sources immediately apparent and encourage user engagement with verification mechanisms."

This highlights a critical gap in user behaviour that can lead to the adoption of inaccurate or misleading health advice. Designers of health information platforms must consider how to embed and prompt users to engage with credibility indicators, rather than assuming users will proactively seek them out.

What This Means for Your Design

People say they check if websites are trustworthy when looking for health info online, but when they actually search, they often don't, and they forget where they found the info.

How to use in your project

1.Use this study to justify the need for user research into how potential users will interact with and trust your design.
2.Cite this to explain why simply providing information isn't enough; the design must guide users to reliable sources.

Paragraph starter

Research indicates a significant disconnect between users' stated intentions to appraise online health information and their actual behaviour, with many overlooking crucial credibility indicators like source verification in favour of superficial cues such as professional design. This suggests that design interventions must proactively guide users towards trustworthy information rather than relying on their independent critical evaluation.
