How to Narrow a Topic into a Research Question

A topic is not a research question. "Social media and mental health" is a topic. "How does daily passive Instagram use predict negative affect in young adults, and does social comparison mediate this relationship?" is a researchable question.

The narrowing process:

Ask these questions to narrow:

• What specific population? (Not "teenagers" but "adolescent girls aged 14 to 17 in high-income countries")
• What specific variable or outcome? (Not "mental health" but "depressive symptoms measured with the PHQ-9")
• What time frame? (Not "historically" but "between 2010 and 2023")
• What mechanism or relationship? (Not "affects" but "increases via social comparison")
