Research integrity may be defined as active adherence to the ethical principles and professional standards essential for the responsible practice of research (Korenman, SG).
Research integrity means conducting research in a way which allows others to have trust and confidence in the methods used and the findings that result from this (University of Bath).
Integrity (from the Latin integritas, meaning whole or complete) refers in ethics to adherence to a code or a usually high standard of conduct. Research integrity thus indicates doing research in accord with standards that properly inform and guide that activity—without deviance under any inappropriate influences. Integrity in this sense has close correlates with authenticity and accountability (Encyclopedia.com)
