What does "minimal risk" mean?

Minimal risk means the probability and magnitude of harm or discomfort anticipated in the research are not greater in and of themselves than those ordinarily encountered in daily life or during the performance of routine physical or psychological examinations or tests.

The IRB interprets the phrase “Ordinarily encountered in daily life or during the performance of routine physical or physiological examination or tests” to refer to normal healthy individuals in general and exclude the risks that certain subcategories of individuals face in their everyday life. For example, the IRB does not evaluate the risks imposed in research focused on a special population against the inherent risks encountered in their work environment (e.g., emergency responder, pilot, soldier in a combat zone) or having a medical condition (e.g., frequent medical tests or constant pain).

For research involving Children as subjects, minimal risk is further defined as the level of risk that a normal, average, healthy child may be exposed to in the course of that child's everyday life, or those risks encountered by normal, average, healthy children living in safe environments in daily life or during the performance of routine physical or psychological examinations or tests.

For research involving Prisoners as subjects, minimal risk is further defined as the probability and magnitude of physical or psychological harm that is normally encountered in the daily lives, or in the routine medical, dental, or psychological examination of healthy persons.

For research subject to Canadian oversight: The probability and magnitude of possible harms implied by participation in the research that is no greater than those encountered by subjects in those aspects of their everyday life that relate to the research.

More information about assessing risk is available under "IRB Guidance", "Assessing Risk Level Using Magnitude of Harm":

Is it possible to conduct human subjects research without interacting with individual subjects?

Yes, if you are obtaining private identifiable information about individuals for research purposes. Definitions of these key terms are as follows:
o “Obtains” means obtaining, using, studying, analyzing, collecting, gathering, or viewing.
o “Private” can refer to data or behavior. "Private" data means that individuals have provided the data for specific purposes in which the individuals can reasonably expect that it will not be made public, e.g., tax record, medical record, or educational record. "Private” behavior means that the information is about behavior that occurs in a context in which an individual can reasonably expect that no observation or recording is taking place.
o “Identifiable” means that the investigator can readily ascertain or associate the information with the individuals’ identities. Examples of identifiers include names, social security numbers, medical record numbers, or a code that permits the data to be linked to individually identifiable living individuals.

If the activity is limited to data analysis (i.e. does not involve interactions, such as data collection, or interventions), then the data being analyzed must be neither private nor identifiable in order for the activity to be considered NOT human subjects research. In other words, if you are analyzing private and identifiable information, you need IRB approval. If you are analyzing data that is neither private nor identifiable, you do not need IRB approval.

If I’m interacting with individuals and obtaining data from them, but the data is not private and identifiable, does this mean I’m not doing human subjects research?

If you’re obtaining data through intervention or interaction with an individual for research purposes, the activity is human subjects research, even when the data is not private and identifiable.

Do oral history activities require IRB review?

In September, 2003, the Office of Human Research Protections (OHRP) issued a letter to the Pennsylvania Historical and Museum Commission concerning the need for review of oral history being collected by the Commission. This letter has led some investigators who make use of oral history in research to ask for clarification of OHRP's position as it affects the need for investigators to apply to for IRB approval.

In response to an inquiry on this topic from Northeastern Illinois University, Dr. Michael Carome of the OHRP issued, on Dec. 1, 2003, a clarification of the Pennsylvania decision as it might apply to other situations. This clarification maintains that if oral history activities meet the federal definition of research according to 45 CFR 46.102(d), then they are subject to IRB review. Most oral history activities are either a) systematic investigations designed to draw conclusions/generalize findings or b) designed to produce materials for permanent archiving in the library.

The following excerpt from Dr. Carome's response to NIU details the circumstances under which oral history does or does not need IRB review and approval:

• Oral history activities, such as open ended interviews, that ONLY document a specific historical event or the experiences of individuals without an intent to draw conclusions or generalize findings would NOT constitute "research" as defined by HHS regulations 45 CFR part 46.

Example: An oral history video recording of interviews with holocaust survivors is created for viewing in the Holocaust Museum. The creation of the video tape does NOT intend to draw conclusions, inform policy, or generalize findings. The sole purpose is to create a historical record of specific personal events and experiences related to the Holocaust and provide a venue for Holocaust survivors to tell their stories.

• Systematic investigations involving open-ended interviews that are designed to develop or contribute to generalizable knowledge (e.g., designed to draw conclusions, inform policy, or generalize findings) WOULD constitute "research" as defined by HHS regulations at 45 CFR part 46.

Example: An open ended interview of surviving Gulf War veterans to document their experiences and to draw conclusions about their experiences, inform policy, or generalize findings.

• Oral historians and qualitative investigators may want to create archives for the purpose of providing a resource for others to do research. Since the intent of the archive is to create a repository of information for other investigators to conduct research as defined by 45 CFR part 46, the creation of such an archive WOULD constitute research under 45 CFR part 46.

Example: Open ended interviews are conducted with surviving Negro League Baseball players in order to create an archive for future research. The creation of such an archive would constitute research under 45 CFR part 46 since the intent is to collect data for future research.

Until the regulations governing the use of human subjects in research are revised or OHRP changes the policies cited above, investigators at Lehigh University must continue to apply to the LU IRB for review and approval of all activities that meet the definition of human subjects research. Investigators requiring advice on whether IRB review is required for a particular project involving oral history should contact the IRB.

I'm unsure if my activity is human subjects research and requires IRB review. What do I do?

Please contact the IRB. Human subjects research determinations are not made via phone or in-person. If you would like a written determination, please email a brief (no more than 1-page Word document) to the IRB at Please include the following information in your synopsis:
o Study funding source.
o Purpose.
o Procedures.
o Draft study measurements (surveys, questionnaires, interview guides, etc.).

The IRB takes full responsibility for its human subjects research determinations.

When can I start working on my study?

Investigators must receive written approval from the IRB before beginning participant recruitment, data collection, or data analysis. An official approval notice will be sent via IRBNet once a protocol is approved.

How long does it take to obtain IRB approval?

The IRB receives a high volume of applications, and most need adjustments before they are considered review-ready. Please plan accordingly and submit your application as soon as possible.

Minimal risk research that meets the exempt criteria listed on the IRB website under "IRB Worksheets" is reviewed by a single committee member. Minimal risk research eligible for expedited review per the criteria listed on the IRB website under "IRB Worksheets" are reviewed by a sub-committee of three IRB members. Applications that may qualify for exempt or expedited review should be submitted at least six weeks in advance of the anticipated start date.

The vast majority of research conducted by Lehigh University is minimal risk. Research that is greater than minimal risk is reviewed by the full committee in a convened meeting. Meetings are scheduled for the second Tuesday of each month. Applications requiring full committee review are required to be submitted to the IRB at least four weeks in advance of the meeting date.

After reviewing, the IRB will often send the investigator a letter that details “Modifications Required to Secure Approval”, which are changes that must be made to the study in order for the IRB to approve/exempt the research. The investigator must take the time to make and submit those modifications, which must be reviewed in turn by the IRB. This process of back-and-forth communication between the investigator and the IRB takes some time.

Who can serve as PI?

The Principal Investigator (PI) has the primary responsibility for protecting the welfare, rights, and privacy of individual subjects in a research project. Those with the academic rank of Professor, Associate Professor, or Assistant Professor at Lehigh University may serve as PI on an IRB protocol application.

Professors of Practice may also serve as PI if the research proposal involves work conducted by students under the supervision of the Professor of Practice in the course of their teaching role.

Research Fellows may serve as principal investigator if the research proposal involves work conducted by the Fellow under the terms of a formal collaborative research agreement or sponsored research agreement with Lehigh University.

In some cases, a research proposal may be submitted by an individual who does not qualify as PI under the policy, or by a non-academic department of the University under the following conditions: a) the individual proposing to conduct the research is a full-time University employee with the requisite qualifications and research experience necessary to conduct such research; and b) the research proposal has been approved in writing by the Vice President or Dean to whom such individual or department reports, with such approval i) indicating that such research is in furtherance of University objective, and ii) accepting responsibility for ensuring that such research will be conducted in compliance with University research policies and procedures.

Can personnel who are not faculty, staff, or students at Lehigh participate in my project?

Yes, but they must complete human research protection training, sign the IRBNet package, and complete an Individual Investigator Agreement. The agreement can be found in the Forms Library on IRBNet. The individual investigator should complete and sign the form. Once the IRBNet application or amendment package is approved, the FWA Institutional Official will countersign the agreement and it will be included with the approval/exemption notice issued to the PI via IRBNet. Note that an Individual Investigator Agreement is only appropriate for individuals who are not faculty, staff or students at FWA-assured institutions. Most universities in the US are FWA-assured. In these instances, an IRB Authorization Agreement for Human Subjects Research (see below) may be more appropriate.

I am collaborating with investigators at another institution. What do I need to know about IRB approval?

When Lehigh University researchers are involved in multi-site research or collaborative projects with investigators at other institutions, IRB review is required at each institution, unless an IRB Authorization Agreement (IAA) is in place. An IAA is a join review arrangement by which one IRB relies on the review of another qualified IRB to avoid duplication of effort. Please see IRB Guidance: IRB Authorization Agreements for Human Subjects Research ( for more information on the types of activities that an IAA can cover and the process for requesting an IAA between Lehigh and a collaborating institution.

When do I need to submit an Amendment/Modification to the IRB to make changes to my study?

Investigators with approved projects must submit an Amendment/Modification application in IRBNet when any study design, informed consent procedures, or the investigator team within an IRB approved research protocol is revised. There is only one exception to this rule, specifically where the change is necessary to eliminate apparent immediate hazards to the subjects. In such cases, the investigator must submit a report to the IRB explaining the protocol deviation.

Amendments/Modifications involving minor changes that pose no more than minimal risk to subjects will be reviewed on an expedited basis. Amendments/Modifications involving changes that pose more than minimal risk will be reviewed by the full committee, at the next available IRB meeting. In general, amendments to protocols considered to be more than minimal risk, are reviewed by the full committee. Similarly, amendments to protocols considered to involve no more than minimal risk, are reviewed via an expedited review process.

Changes may not be implemented until the Principal Investigator receives final written IRB approval for the change.

Some examples of situations that require that an amendment application be submitted for IRB review:
• Changes in the content of a previously-approved personal interview, telephone interview, or self-administered questionnaire – new or substantially rewritten questions (you do not need to report typos and minor wording changes)
• Review of the final interview or questionnaire for a previously approved study
• Addition of new consent or assent forms
• Changes to any of the consent forms or scripts
• Changes to the aspect of the informed consent process, including oral consent
• Changes in the population studied, e.g. including minors as well as adults
• Changes in study recruitment procedures, e.g. changing from telephone to email recruitment
• For focus groups, major changes in recruitment procedures or aims
• Changes in the mode of administration of a study, e.g. from mail or telephone to web or Internet access
• Change in the amount of compensation or method of providing compensation
• Changes in the leadership of a research project, e.g. change in the principal investigator, adding a co-investigator, changing faculty adviser.
• Addition of personnel who will interact with human participants or have responsibility for research data
• Data set enhancements, such as merging community, company, or neighborhood level data into survey records
• Any changes in research design
• Addition of study locations

Can my study be approved retroactively?

No. The federal regulations do not allow for IRB approval of research that has already been conducted. If data was collected for purposes that the IRB determines to be non-research (e.g. program evaluation not initially intended to be used for research), IRB approval can be sought for the data analysis going forward.

My project is finished. Do I need to tell anyone?

IRB approval must be maintained as long as a project continues to involve human subjects. A research project no longer involves human subjects and can be closed once all research-related interventions / interactions with human subjects have been completed, and all data collection and analysis of identifiable private information (or identifiable biospecimens) as described in the IRB-approved protocol has been finished. No further interactions or interventions with human subjects and no further analysis involving identifiable information will take place.

To close a protocol, email confirmation that the above conditions apply to Include your protocol title and your IRBNet numbers. The email must come from directly from the PI or the PI must be cc’d on the email.

What is the difference between "privacy" and "confidentiality", and why are they relvant to research with human subjects?

Per HHS and FDA Regulations, 45 CFR 46.111(a)(7) and 21 CFR 56.111(a)(7)), the IRB shall determine that where appropriate, there are adequate provisions to protect the privacy of subjects and to maintain confidentiality of data in order to approve human subjects research. The committee must consider the sensitivity of the information collected and the protections offered the subjects. Privacy and confidentiality are also supported by two principles of the Belmont Report:
Respect for persons – Individuals should be treated as autonomous agents able to exercise their autonomy to the fullest extent possible, including the right to privacy and the right to have private information remain confidential.
Beneficence - Maintaining privacy and confidentiality helps to protect participants from potential harms including psychological harm such as embarrassment or distress; social harms such as loss of employment or damage to one‘s financial standing; and criminal or civil liability.

Maintaining privacy and confidentiality helps to protect participants from potential harms including psychological harm such as embarrassment or distress; social harms such as loss of employment or damage to one‘s financial standing; and criminal or civil liability. Especially in social/behavioral research, the primary risk to subjects is often an invasion of privacy or a breach of confidentiality.

Privacy is the control over the extent, timing, and circumstances of sharing oneself (physically, behaviorally, or intellectually) with others. For example, persons may not want to be seen entering a place that might stigmatize them, such as a pregnancy counseling center clearly identified by signs on the front of the building. The evaluation of privacy also involves consideration of how the researcher accesses information from or about potential participants (e.g., recruitment process). IRB members consider strategies to protect privacy interests relating to contact with potential participants, and access to private information.

Privacy is:
• About people
• A sense of being in control of access that others have to ourselves
• A right to be protected
• Is in the eye of the participant, not the researcher or the IRB.

Confidentiality pertains to the treatment of information that an individual has disclosed in a relationship of trust and with the expectation that it will not be divulged to others without permission in ways that are inconsistent with the understanding of the original disclosure.

During the informed consent process, if applicable, subjects must be informed of the precautions that will be taken to protect the confidentiality of the data and be informed of the parties who will or may have access (e.g., research team, FDA, OHRP). This will allow subjects to decide about the adequacy of the protections and the acceptability of the possible release of private information to the interested parties.

• Is an extension of privacy
• Is an agreement about maintenance and who has access to identifiable data
• In regards to HIPAA, protects patients from inappropriate disclosures of Protected Health Information (PHI).

Privacy is about people. Confidentiality is about data.

How can researchers protect participants' privacy?

The IRB decides on a protocol-by-protocol basis whether there are adequate provisions to protect the privacy of subjects at each segment of the research from recruitment to maintenance of the data.

In regards to privacy, researchers should consider and address following issues in their IRB application:

The proposed subject population?
o What are the cultural norms of the proposed subject population? Some cultures are more private than others.
o What are the ages of the proposed subject population? There may be age differences in privacy preferences (e.g., teenagers less forthcoming than older adults)

The proposed recruitment methods: How are potential participants identified and contacted?
Acceptable recruitment methods:
o advertisements, notices, and/or media
o introductory letter to colleagues to distribute to eligible individuals – interested individuals contact researcher
o primary care staff contact those patients that qualify to determine interest
Unacceptable recruitment methods:
o search through medical records for qualified subjects or existing database (e.g., registry); then have a researcher with no previous contact with potential subject recruit; this method violates the individuals' privacy
o recruit subjects immediately prior to sensitive or invasive procedure (e.g., in pre-op room)
o retain sensitive information obtained at screening without the consent of those who either failed to qualify or refused to participate for possible future studies participation
• Sensitivity of the information being collected – the greater the sensitivity, the greater the need for privacy

Method of data collection (focus group, individual interview, covert observation)
o Will subjects feel comfortable providing the information in this manner?
o If passively observing the subject; could the individual have a reasonable expectation of privacy (e.g., chat room for breast cancer patients)?
o Will the researcher collect information about a third party individual that is consider private (e.g., mental illness, substance abuse in family)? If yes, informed consent should be obtained from third party?

Privacy is in the eye of the participant, not the researcher or the IRB

What must researchers know about maintaining confidentiality?

The IRB also decides on a protocol-by-protocol basis whether there are adequate provisions to maintain the confidentiality of the identifiable data at each segment of the research from recruitment to maintenance of the data. Protocols should be designed to minimize the need to collect and maintain identifiable information about research subjects. If possible, data should be collected anonymously or the identifiers should be removed and destroyed as soon as possible and access to research data should be based on a “need to know” and "minimum necessary" standard.

When it is necessary to collect and maintain identifiable data, the IRB will ensure that the protocol includes the necessary safeguards to maintain confidentiality of identifiable data and data security appropriate to the degree of risk from disclosure.

In regards to when it is appropriate to require provisions to maintain confidentiality of data, the following issues should be considered:
o Will confidentiality of identifiable data be offered?
o Are there additional legal/ethical requirements (e.g., HIPAA)?
o Will the release of data cause risk of harm?

Have the rules/regulations governing the IRB and human subjects research changed recently?

Ending five and a half years of rulemaking and speculation, the US Department of Health and Human Services (HHS) and 15 other Federal Agencies released a final revision of the Federal Policy for the Protection of Human Subjects, or “Common Rule,” on January 19, 2017. These are the first revisions to the Common Rule since it was promulgated in 1991. The official rule was published in the federal register here:

The compliance date for most of the Rule’s provisions is currently January 21, 2019. For the requirement to use a single IRB for multi-site research, the effective date is January 20, 2020.

Lehigh University has implemented changes to our policies and procedures to align with the Common Rule revisions. Updates have been posted to the IRB website and communicated broadly with the Lehigh University community.

What is required when conducting research internationally or with non-English speaking populations in the US?

Please see the IRB's detailed guidance documents, flow charts, and forms at the following page:

Are IP addresses considered "individually identifiable information?"

An IP address is a unique identifying number used to identify specific computers connected to the Internet. While not as directly identifiable as other pieces of information, such as email addresses, IP addresses are typically considered identifiable information, as in many cases, an IP address can be used to locate a specific computer on a given network at a specific point in time. In some situations, an IP address can also be used to determine the geographic location of a specific computer or connected network. For this reason, researchers should refrain from collecting IP addresses unless necessary for scientifically justifiable reasons. Most online survey research platforms allow for IP address collection to be disabled. For example: Qualtrics -- and SurveyMonkey --

Is the use of passive consent / opt-out consent procedures permitted in obtaining parental consent/permission?

Passive parental consent (sometimes referred to as "opt-out" consent), whereby children are assumed to participate in a given research project unless a parent/guardian specifically opts the child out of participating, is permitted only under very specific circumstances. In order to use a passive parental consent process, the research must qualify for a waiver/alteration of informed consent, as the requirement to obtain parental permission is being altered by this opt-out consent request. Specifically, the research must by determined by the IRB to involve no more than minimal risk, the waiver may not adversely affect the rights and welfare of the subjects, the study may not be practicably carried out without this waiver/alteration of the normal parental permission consent process, and the selection of subjects must be fair, equitable, and not exclusionary. Furthermore, parents must be given sufficient time to consider whether they wish for their child(ren) to participate in the study, as well as provided ample time and opportunity to ask questions of the researchers. This information must be conveyed to the parents in the form of a written document that contains all required elements of informed consent.

I am engaged in entrepreneurial activity rather than traditional human subjects research. Under what conditions is IRB review required?

The need for IRB review and approval is evaluated based on the specific activities being proposed, and not the research discipline of the individual / group proposing these activities. If an individual is engaged in any research activity meeting the criteria for “human subjects research” then IRB review is required prior to the start of that activity.

Individuals, regardless of their area or discipline, are encouraged to review the human subjects research criteria and to reach out to the Office of Research Integrity for further assistance in determining whether they are engaged in human subjects research requiring IRB review and approval.
