Reviewable Questions Across Seven Academic Fields

What makes a topic reviewable

A workable question passes three tests. It has enough published research, contains a live disagreement, and can be bounded without making the boundary look arbitrary.

Source needs depend on length. A 2,000 to 3,000-word standalone review can usually compare 15 to 30 substantive sources. A 5,000-word paper may need 35 to 60. Ten nearly identical studies are less useful than ten studies that differ in method, population, theory, or result.

Look for disagreement rather than a topic label. Instead of reviewing social media and mental health, ask whether heavy social media use causes adolescent depression or mainly reflects vulnerabilities that were already present. That question gives you positions to compare, methodological weaknesses to assess, and a reason for the review to exist.

Your boundary should follow the question. You might limit evidence by age group, country, study design, publication period, platform, or measured outcome. A defensible boundary changes what evidence can answer the question. A convenient boundary merely cuts the reading list.

The publication estimates below are directional. Database coverage and search wording can change a count substantially, so confirm each topic in the databases used by your course.

Psychology

1. Social media use and adolescent depression. The debate concerns whether use causes poorer mental health or whether existing distress predicts heavier use. Several thousand studies and dozens of systematic reviews are available, though a tighter age or platform boundary is advisable.

2. Cognitive behavioral therapy versus antidepressants. Researchers disagree about comparative effectiveness, relapse prevention, side effects, and the value of combined treatment. You can find hundreds of trials and more than 100 reviews focused on adult depression.

3. Trigger warnings and emotional distress. The dispute is whether warnings protect vulnerable readers or increase anticipatory anxiety without reducing distress. Roughly 50 to 100 empirical studies and several recent meta-analyses make this suitable for a focused review.

How to scope a review that is turning out too large

Start by recording your actual search. Keep the database, search terms, filters, and result count. If one search returns 8,000 records, do not solve the problem by reading only the first page. Change the question.

Limit one dimension at a time. A review of telehealth for chronic disease can become telehealth for type 2 diabetes, then video consultations for adults with type 2 diabetes, then video consultations used for glycemic management in US primary care since 2020. Stop narrowing when a trial search produces enough comparable studies for your required length.

Population is often the cleanest boundary. Age, diagnosis, occupation, education level, and risk group affect what evidence means. Setting also works well. Findings from hospitals may not transfer to home care, just as evidence from universities may not answer a question about elementary schools.

Choose outcomes before reading deeply. Productivity, job satisfaction, retention, and stress are different outcomes even when every study concerns remote work. A review that mixes them without explanation will struggle to reach a defensible judgment.

You can also restrict study design. Randomized trials suit questions about intervention effects, while interviews may be needed for questions about experience or implementation. Do not exclude a design merely because its findings complicate your argument.

Set a publication period only when the dates have an intellectual reason. A boundary beginning in 2020 makes sense for pandemic-era telehealth. Choosing the last five years because it produces fewer results is harder to defend unless technology, policy, or theory changed during that period.

Draft a one-sentence inclusion rule. For example, you might include peer-reviewed empirical studies published from 2018 onward that compare hybrid and office work among salaried knowledge workers and report a measured productivity outcome. If a source does not meet that rule, set it aside.

If your search still produces more than 100 plausible sources for a 3,000-word paper, narrow another variable. If it produces fewer than 10, remove one restriction or search for related terminology used by researchers.

If you want help turning the final scope into a complete paper, Assignment Masters can prepare a literature review to your instructions, source requirements, and deadline.
