When reviewing a study for ethical approval, several key elements are considered: - Informed Consent: Ensuring that participants are fully aware of the study’s nature, purpose, risks, and benefits. - Confidentiality: Safeguarding the privacy and personal data of participants. - Risk-Benefit Analysis: Weighing the potential risks to participants against the anticipated benefits of the research. - Vulnerable Populations: Providing extra protections for groups that might be at greater risk of coercion or harm, such as children or those with cognitive impairments.
