The Institutional Review Board, or IRB, is a committee that is designated by an academic institution to review and approve research involving human subjects. The purpose of IRB review is to ensure that all research conducted at the institution adheres to ethical standards and protects the rights and welfare of human participants. Obtaining IRB approval is required for any dissertation research that involves collecting data from or about living human beings.
The IRB approval process typically begins early in the dissertation process, usually after a student has selected their dissertation topic and developed their dissertation proposal. Most institutions require students to complete IRB training to learn about ethical guidelines and regulations regarding human subjects research. Training certificates need to be submitted along with the initial IRB application. Students then work with their dissertation committee chair to complete a lengthy IRB application form providing details of their proposed research methodology, participant recruitment processes, data collection instruments, informed consent documents, and plans for securely storing data.
Applications are typically submitted online through the institution’s IRB system. Supporting documents like consent forms, surveys, interview scripts, etc. are uploaded as well. The level of review required is determined based on the type of research – expedited or full board review. Expedited reviews can be approved by one IRB reviewer while full board reviews require evaluation and approval by the entire IRB committee at their scheduled meeting. Review times can vary greatly depending on committee schedules and volume of applications but on average take 4-6 weeks for approval.
Committees look closely at whether potential risks to participants have been minimized, the risks are reasonable in relation to anticipated benefits, selection of participants is equitable, informed consent is sought from each prospective participant, and whether privacy and confidentiality of participants will be maintained. Students may be asked to modify aspects of their proposed methodology or consent processes based on IRB feedback to strengthen protections for human subjects. Revisions sometimes require re-review by the full committee before final approval can be granted.
Conditional or provisional approval is possible in some cases allowing students to begin recruiting participants and collecting preliminary data, but full approval signatures are still needed before final dissertation defense. Multi-site studies involving more than one institution each require separate IRB approval from every organization. International research brings additional complexities around cultural norms, language barriers, and variations in regulatory standards between countries.
Once approved, most IRB approvals are only valid for one year and any changes to the approved research protocol requires an amendment submission for review and approval. Projects that go longer than a year require continuing review and re-approval. Students are responsible for promptly reporting unexpected problems, adverse events, protocol deviations and other unanticipated issues which arise during their research. At the end of the project, a final report communicating the study’s completion needs to be filed with the IRB.
Obtaining IRB approval for dissertation research is an essential part of upholding ethical standards and safeguarding human subjects but also adds time, paperwork and oversight obligations to already demanding doctoral requirements. Careful planning, compliance with policies, and open communication with IRB representatives helps navigate what for many students is their first experience with formal research ethics review processes.
The IRB approval process for dissertations serves to protect the rights and welfare of research participants through robust ethical guidelines and regulatory oversight, which students must understand and adhere to in order to gain permission to involve people in their scholarly inquiry and degree requirements involving human subjects research. Planning early and working closely with IRB staff helps ensure a smooth review and can help accelerate approval timelines.
