Who qualifies as a human subject in research?

A human subject in research is defined as a living individual from whom data is obtained through interaction or intervention, or whose private information is used in research. This definition emphasizes the necessity of the individual being alive and actively participating in the research setting, either through direct engagement—such as clinical trials, surveys, or interviews—or indirectly through the collection of personal data.

The emphasis on interaction or intervention is crucial. It ensures that the individual's contributions, whether through physical engagement or the provision of information, are the focal point of the study. This broad inclusivity allows for varied types of research, ranging from clinical to social sciences, thereby underpinning important ethical considerations surrounding informed consent, confidentiality, and the welfare of participants.

The other options do not meet the criteria established for defining a human subject. For instance, financial information alone does not create a context of involvement in research. Consent for medical procedures does not universally apply to all research scenarios, as consent is specifically tied to the context of the study. Additionally, individuals involved in healthcare administration do not qualify as human subjects unless they are providing personal data pertinent to the research, as their role is more about the organizational aspect rather than the individual intervention or interaction required for research classification.
