• Objectives are clear statements about why a specific research study is being done. Objectives are more specific than a general health question. While an example of a general health question is “How can we further reduce the risk of mother-to-child transmission?”, the specific objective of the study in this picture is “Which medicine is more effective in reducing mother-to-child transmission of HIV—Medicine A or Medicine B?”
• A health question is general, while an objective is very specific.
