What are the ethical issues surrounding this study at the beginning and when the decision was made to terminate the study?
When you discuss the ethical issues of the STEP study think in terms of the four major Principles of Ethics which are listed below:
Respect for Persons (autonomy)
Beneficence,
Nonmaleficence and
Justice
Please refer to your textbook for information about The Belmont Report and about these principles.
Please also refer below where I have provided a link to more information about the four major Principles of Ethics.
Please remember to write a response that is specific to context of the scenario presented (i.e. in terms of The STEP Study). Use your research to inform your discussion.
