Institutional Review Board

Institutional Review Board (IRB) protects the rights and welfare of individuals participating in research conducted by the university.

The IRB is an independent committee, comprising of scientific and non-scientific members, that reviews and approves research studies involving human subjects and associated protocol amendments.

Collaborative Institutional Training Initiative Certification

Principal Investigators and Co-Investigators of IRB studies must be certified by the Collaborative Institutional Training Initiative (CITI). CITI Program is a US-based organisation, dedicated to promoting the public’s trust in research enterprises by providing high quality, peer-reviewed, web-based educational courses in research, ethics, regulatory oversight, responsible conduct of research, research administration, and other topics pertinent to the interests of member organisations and individual learners.

Through this training, researchers will ensure that all human biomedical research carried out follows the law and principles of good clinical practice relating to ethics, science, information, health and safety of participants, and adheres to Singapore’s Human Biomedical Research Act (HBRA). This will ensure that research protocols are conducted with integrity, and are of reliable quality, such that the health, welfare and safety of research participants remain the paramount consideration at all times.

Researchers will also be taught the principles of data protection, focusing on healthcare-related privacy, information security requirements, educational records and data-related requirements, which also complies with Singapore’s Personal Data Protection Act (PDPA). Researchers must ensure both the rights of individuals to protect their personal data, including rights of access, correction, and the needs of organisations to collect, use or disclose personal data for legitimate and reasonable purposes.

    Does my research study require IRB review and approval?

    All human biomedical research conducted by staff and students involving the use of human subjects (e.g. human participants) must be reviewed and approved by the Institutional Review Board (IRB).

    (a) the prevention, prognostication, diagnosis or alleviation of any disease, disorder or injury affecting the human body;
    (b) the restoration, maintenance or promotion of the aesthetic appearance of human individuals through clinical procedures or techniques; or
    (c) the performance or endurance of human individuals,

    where the research involves –

    (i) subjecting an individual to any intervention (including any wilful act or omission) that has a physical, mental or physiological effect (whether temporary or permanent) on the body of the individual;
    (ii) the use of any individually identifiable biological material obtained from the human body; or
    (iii) the use of any individually identifiable health information.

    Human biomedical research includes any research involving human gametes or human embryos, cytoplasmic hybrid embryos etc.

    For the avoidance of doubt, research involving any of the following methods needs to be reviewed by the IRB:

    • Observational Studies
    • Interventions within specific groups
    • Surveys or interviews
    • Educational tests
    • Analysing human subject data
    • Secondary use of data (containing personal identifiers) that are not in the public domain.

    What is a “research” study?

    The IRB defines “research” to mean any systematic investigation with the intention of developing or contributing to generalisable knowledge including publication, seminar, public sharing.

  3. chevron--up
    What is a “human subject”?

    In the context of research, the human subject may be a participant in the study. If you are conducting human biomedical research, the Human Biomedical Research Act (2015) defines a "research subject" as a natural person, whether living or dead

    (a) whom a researcher involves in human biomedical research; or
    (b) from whom human biological material or health information is obtained for use in human biomedical research.

  4. chevron--up
    Who can apply for IRB approval?
    • Applications should be submitted by SIT staff and students as the PI or Co-I in the study.
    • If the PI is external, and the SIT staff/ student is the Co-I, we will only process the application if the PI’s institution does not have an IRB to apply to.
    • If the PI is external and has received approval from his/ her institution’s IRB, the SIT Co-I would still need to apply to the SIT-IRB if the subjects are SIT staff/ students and/ or SIT premises will be used in the study.
  5. chevron--up
    How can I apply for IRB approval?

    The application forms can be downloaded from Sharepoint, which can only be accessed by SIT staff.

    Please determine if your study will require Exempted or Expedited/ Full Board Review, and download the appropriate form from Sharepoint. You may check with the IRB if you are unsure.

  6. chevron--up
    How can I determine if my study is HBR or SBER?

    Please refer to Q4 for the definition of Human Biomedical Research (HBR) as defined by the Ministry of Health, Singapore. If your research does not meet the definition of HBR, it is SBER.

  7. chevron--up
    What are the documents I need to submit?

    The following documents need to be submitted to the IRB for review. 

    1. IRB Application form, duly signed by PI, Co-I, and the Cluster Director or his/ her representative. Note: In Expedited/ Full-Board Applications the collaborator(s) must sign as well.
    2. Participant Information Sheet and Consent Form (PIS-CF)

    Full Review

    Expedited Review

    Exempted Review

    Risk Exposure

    More than minimal risk e.g. research involving vulnerable populations, involving sensitive questions, etc

    Minimal risk or remote risk e.g. surveys or interviews on sensitive topics

    No likelihood of harm e.g. anonymous surveys or interviews

    Expected Duration of Review

    4 weeks and above

    Between 2 to 4 weeks

    At least 1 week

    Note: Review duration will depend on PI’s response time to address queries, provide clarifications and make amendments based on the secretariat’s and/ or reviewer’s comments.

  17. chevron--up
    When can I start my research study?

    Upon notification of approval from the IRB.

  18. chevron--up
    What is a protocol amendment?

    A protocol amendment constitutes any changes made to an ongoing approved application (e.g. changes in methodology, recruitment method). This includes the addition or removal of investigators. PI should only implement the changes when the IRB has approved the protocol amendment.

  19. chevron--up
    How do I apply for a protocol amendment?

    Send the duly filled up protocol amendment form to the secretariat will all the necessary documents to support the request for the amendment. If there is a change in PI/ Co-I a copy of the curriculum vitae (CV) and CITI certificate has to be submitted along with the application form.

  20. chevron--up
    Can I apply for IRB approval after I have completed my research study?

    IRB does not conduct retrospective reviews on research that have been already completed as these could be problematic. In particular, changes cannot be made to the research methodology if ethical issues are uncovered, e.g.

    a. Research participants were not informed that their participation in class activities was part of a research study
    b. Consent had not been sought for their participation or participant did not agree to their data being used for research purposes.

  21. chevron--up
    What sort of training is available for researchers to ensure proper ethical practice?

    The Collaborative Institutional Training Institute (CITI) certification is a good place to start. SIT has registered with CITI, and you may take their online modules to learn and attain their certification. Please contact the secretariat for details.

    The Personal Data Protection Commission (PDPC) of Singapore provides online learning on data protection, data security, personal data protection, etc. Please view the PDPC Interactive learning tool for more information.
