Dr. Smith is conducting research on the effects of social media use on adolescent self-esteem. This raises ethical issues regarding informed consent from minors, privacy of social media data, potential harm, and deception. To resolve these issues, Dr. Smith obtains consent from adolescents and parents, anonymizes private data, implements measures to minimize harm, and informs participants of the general research without compromising validity. Addressing these ethical considerations helps ensure the research is conducted respectfully and for the benefit of participants.
