Addressing Stigma and Enhancing Clarity through Evidence‐Based Naming and Segmentation Strategies
Abstract
The term “clinical trial” is widely used in medical research; however, it can inadvertently evoke negative perceptions associated with experimentation, risk, and a loss of personal autonomy. This white paper examines the evidence behind such stigma and offers alternative, evidence‐informed terminology. In addition, it argues for the segmentation of research language to accurately reflect the diversity of study designs and objectives. Tailoring terminology to the specific attributes of each study can enhance patient comprehension, build trust, and improve participation in research.
Introduction
Effective communication is critical to ensuring informed consent and engaging patients in research. Recent evidence suggests that the term “clinical trial” may carry unintended negative connotations that contribute to participant hesitancy (Jenkins & Fallowfield, 2000; Fallowfield, Jenkins, & Farewell, 2002). This paper explores the stigma associated with the term, reviews alternative nomenclatures that could reduce misinterpretation, and discusses the benefits of segmenting research terminology rather than applying a single, undifferentiated label.
Stigma and Connotations Associated with “Clinical Trial”
The word “trial” can suggest that participants are subject to uncontrolled experimentation, evoking images of being treated as “guinea pigs.” Such connotations may increase anxiety and reduce willingness to participate in research, a finding supported by studies on decision framing (Tversky & Kahneman, 1981). In addition to the implication of experimentation, the term may also carry judicial and legalistic overtones that amplify concerns about uncertainty regarding risk and accountability (Jenkins & Fallowfield, 2000). This negative framing has been linked to reduced recruitment rates, particularly among populations sensitive to the experimental nature of medical research (Fallowfield, Jenkins, & Farewell, 2002).
Evidence-Based Alternative Naming Suggestions
Alternative terminology has been proposed to mitigate these negative perceptions while preserving the clarity and integrity of research communications. The term “clinical study” is generally perceived as more neutral and descriptive, emphasizing systematic inquiry over the notion of experimentation. Patient feedback and survey data indicate a preference for “clinical study,” as it can foster a more collaborative and less intimidating perception (Jenkins & Fallowfield, 2000). Another suggested term is “medical research study,” which highlights the broader goal of advancing medical knowledge and underscores collaboration rather than experimental risk. The inclusion of the word “research” contributes to a more positive and cooperative image, aligning with efforts to build trust (Fallowfield, Jenkins, & Farewell, 2002). For studies that involve specific treatments or interventions, the term “interventional study” accurately describes the methodology while avoiding the charged language associated with “trial.” Although this term is precise, it may require additional context to ensure full understanding by lay audiences. Similarly, “health research study” emphasizes the ultimate goal of improving public health and can be particularly effective in community-focused communications, though it must be used with clear explanations of study design and objectives.
Segmenting Research Terminology: Moving Beyond a Lowest Common Denominator
Using a single alternative label for all research studies risks oversimplifying the diversity of study designs. Segmenting research terminology allows for greater precision in communication, as it differentiates between various phases and types of research. For example, early-phase investigations intended to test procedures may be best described as pilot or feasibility studies, while research designed to determine the optimal conditions for treatment efficacy may be labeled as efficacy studies. Observational studies, which involve monitoring outcomes without intervention, and implementation studies, which focus on applying research findings in clinical practice, also require specific designations. This tailored language reinforces the unique design and objectives of each study, thereby enhancing credibility and trust. In addition, customized terminology enables the development of targeted educational materials that help prevent all studies from being perceived as a homogeneous group with a negative connotation.
Implementation Considerations
Clear, patient-friendly explanations should accompany any new or segmented terminology. Consent forms and informational materials must provide accessible descriptions that explain the specific purpose and design of the research. Consistency in the use of segmented terminology—from academic publications to patient recruitment materials—is essential to minimize confusion and foster trust among potential participants. Furthermore, healthcare providers and research staff should receive training on the nuances of these terms to ensure accurate and effective communication of study details. Ongoing stakeholder feedback is critical for refining language and improving communication strategies over time.
Conclusion
The conventional term “clinical trial” may inadvertently contribute to negative perceptions of medical research. Evidence supports the use of alternative terminology, such as “clinical study” or “medical research study,” to mitigate stigma and enhance participant engagement. Moreover, segmenting research terminology to reflect the specific nature of each study type improves clarity and credibility by avoiding an oversimplified, lowest common denominator approach. Embracing these evidence-based strategies can foster a more transparent, patient-centered research environment and ultimately enhance the recruitment and retention of study participants.
