Ethics & Mixed Methods

Ethics & Mixed Methods

In this module, the ethical considerations of qualitative and quantitative research are discussed as related to mixed methods research.

Learning Objectives

  • Describe why adhering to ethical principles is important in research
  • Explain the specific ethical issues to consider in quantitative and qualitative research and why it is important to consider both kinds of issues when using mixed methods
  • Describe the purpose and function of the Institutional Review Board


Ethical considerations in research are critical. Ethics are the norms or standards for conduct that distinguish between right and wrong. They help to determine the difference between acceptable and unacceptable behaviors on the part of the researcher. Why are ethical considerations so important in research? The integrity, reliability and validity of the research findings rely heavily on adherence to ethical principles. The readers and the public want to be assured that researchers followed the appropriate guidelines for issues such as human rights, animal welfare, compliance with the law, conflicts of interest, safety, health standards and so on. The handling of these ethical issues greatly impact the integrity of the research project and can affect whether or not the project receives funding.

Because ethical considerations are so important in research, many professional associations and agencies have adopted codes and policies that outline ethical behavior and guide researchers. These codes address issues such as honesty, objectivity, respect for intellectual property, social responsibility, confidentiality, non-discrimination and many others. These codes and policies provide basic guidelines, but researchers will still be faced with additional issues that are not specifically addressed and this will require decision-making on the part of the researcher in order to avoid misconduct. The resources on this page address many of those issues and the case studies used in these resources provide excellent examples of these types of issues.

Ethical issues are important in all types of research. Regardless of the type of research, the researcher should take into consideration both general research principles and those that are more specific to the type of research. When conducting mixed methods research, it is important to adhere to the principles of qualitative and quantitative research ethics. In quantitative research, ethical standards prevent against such things as the fabrication or falsifying of data and therefore, promote the pursuit of knowledge and truth which is the primary goal of research. Dr. Jaap van Harten, the Executive Publisher of Elsevier, shares insights about research and publishing ethics, data manipulation, plagiarism, publication duplication, and the consequences of scientific misconduct. The Elsevier webpage offers a series of short videos in its Ethics Toolkit that address a variety of issues related to ethics in quantitative research. To view these videos in the series, go to Elsevier Ethics Toolkit.

In qualitative research, ethical principles are primarily centered on protecting research participants and the guiding foundation of “do no harm”. Following is a list of core ethical principles that are important in qualitative research:

  • Respect for persons – Respect the autonomy, decision-making and dignity of participants.
  • Beneficence – Minimizing the risks (physically, psychologically and socially) and maximizing the benefits to research participants.
  • Justice – Participants should be selected from groups of people whom the research may benefit.
  • Respect for communities – Protect and respect the values and interests of the community as a whole and protect the community from harm.

To address these considerations, most institutions and organizations have developed an Institutional Review Board (IRB). An IRB is a panel of people who help to ensure the safety of human subjects in research and who assist in making sure that human rights are not violated. They review the research methodology in grant proposals to assure that ethical practices are being utilized. The use of an IRB also helps to protect the institution and the researchers against potential legal implications from any behavior that may be deemed unethical.

Examples of some of these issues include voluntary participation and informed consent. These principles are followed to guarantee that all human subjects are choosing to participate of their own free will and that they have been fully informed regarding the procedures of the research project and any potential risks. Potential participants must be competent to make a decision regarding participation and must be free from any coercion. The consent may be given in a written or oral form depending on the nature of the research. Ethical standards also protect the confidentiality and anonymity of the subjects. Researchers should not share information between participants and should have procedures in place to protect the data and names of participants.

The following Slideshare presentation, Ethics in Qualitative Research, offers an overview of ethical considerations. In addition to the consideration discussed above, the presentation also addresses the ethical concerns related to “access” to research participants.

While it is true that mixed methods research requires researchers to be aware of and adhere to the ethical guidelines of both quantitative and qualitative research, it should not present a significant challenge. Researchers should want to do everything possible to ensure the results of the study are meaningful and valid and it is vital that they do so to protect the integrity of the study.
