Pre-Feedback Risk Expectancies and Reception of Low-Risk Health Feedback: Absolute and Comparative Lack of Reassurance.
Gamp, Martina, Renner, Britta · Applied psychology. Health and well-being · 2016 · DOI
Quick Summary
This study looked at how people react when they receive good news about their health risk. Researchers found that if someone expected to be at high risk for a condition but then received test results showing they were actually at low risk, they often didn't feel reassured. Instead, these people continued to feel worried about their health, even though the test results were positive.
Why It Matters
This research is relevant to ME/CFS patients because many experience long diagnostic odysseys with prior expectations of being healthy before receiving a chronic illness diagnosis. Understanding how expectations shape responses to health information may help clinicians and patients communicate more effectively about risk and prognosis, potentially reducing unnecessary health anxiety or conversely preventing premature reassurance.
Observed Findings
- Participants expecting high risk but receiving low-risk feedback showed significantly greater perceived personal risk than those receiving expected good news.
- The unexpected low-risk group reported risk levels equal to (Study 1) or exceeding (Study 2) their perceived peer risk despite receiving favorable feedback.
- Pre-feedback risk expectancies moderated the reassuring effect of positive health feedback across both studies.
- Participants who expected low risk and received confirming good news showed expected reassurance.
Inferred Conclusions
- High pre-feedback risk expectancies can eliminate or reverse the reassuring effects of objectively good health news.
- Expectancy-inconsistent feedback may activate defensive or skeptical processing rather than acceptance.
- Personalised health risk feedback effectiveness depends not only on the objective risk level but also on alignment with prior expectations.
Remaining Questions
- Do these expectancy effects persist over time or fade with repeated exposure to the low-risk feedback?
- How do these findings apply to patients with real diagnoses like ME/CFS versus healthy controls in hypothetical scenarios?
- What mechanisms explain why discordant feedback fails to reassure—disbelief, distrust, or cognitive adjustment?
What This Study Does Not Prove
This study uses a fictional disease and healthy volunteers, not actual ME/CFS patients, so findings may not directly transfer to real diagnostic or prognostic scenarios. The cross-sectional design cannot establish causation or determine whether expectancy-discordant feedback produces lasting changes in behavior or health outcomes. Results may reflect laboratory effects rather than real-world responses to actual medical feedback.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
