How to Write a Screener Survey for User Research Studies

A screener survey is the short set of questions that decides who gets into your study, and writing one well is the difference between talking to real users and talking to people who are good at qualifying. The Nielsen Norman Group puts the goal plainly: “you’ll get more meaningful insights if your study participants have the same behaviors, interests, and knowledge as your actual users.” The screener is how you make sure they do.

This guide covers the one tension every screener has to manage, how to write behavioural questions people cannot game, when to use open-ended versus multiple-choice, and the small tricks that catch over-eager respondents. It assumes you have already decided who you are looking for; if not, start with how to recruit users for testing.

The tension every screener manages

A screener has, in NN/G’s words, “two conflicting goals”: it must elicit specific information about the user while it avoids revealing information about the study. Those pull against each other, and getting the balance right is, as NN/G argues, the most reliable way to end up with the right participants. The moment a respondent works out what you are looking for, some will, as NN/G warns, “be tempted to exaggerate their responses just so they can participate.” Every technique below exists to keep the right people in without telling them what “right” looks like.

A good screener finds your users without ever telling respondents which answer gets them in.

Ask about behaviour, not self-assessment

The single most useful rule. Do not ask people to rate or label themselves, ask what they actually do. NN/G’s example: instead of “do you play online games?”, ask “what activities do you do online?” and select the people who mention games unprompted. For depth, ask someone to name their favourite games and say why. As NN/G notes, that “will quickly” separate the committed player from the person who plays a few times a year but would happily claim otherwise.

Open-ended or multiple-choice

Both have a place, and the choice is a real trade-off.

Open-ended questions are hardest to game, because, as NN/G puts it, “there are no answer choices provided, it’s difficult for people to guess which answer is right.” They are ideal for occupation and experience. The cost is analysis: they “require more time to produce and also more time to collect and to analyze,” and some genuine users simply will not mention the behaviour you care about in a general answer.

Multiple-choice questions are fast to evaluate, but only if you hide the target answer among realistic distractors, plausible wrong options. NN/G’s illustration: asking how someone would travel two miles to a meeting, “walk / rent a bike / rent a scooter / take an Uber” works, because every option is realistic; slipping in “hang glide” gives the game away. Distractors have to be believable both as things people do and as topics a company might research.

Catch the over-eager

Some respondents want in badly enough to game the screener, and there are cheap ways to catch them.

• Exclude anyone who selects every option in a question. NN/G calls this out directly: selecting all the answers is a tell that someone is trying too hard to qualify.
• Lead with a soft disqualifier so unqualified people drop out before they have invested effort, and before they can infer what you want.
• Keep it short. A screener is a filter, not the interview. NN/G notes that even a single well-written question with good distractors can identify the right audience.

A bad question, rewritten

Say you are recruiting people who manage a team’s software budget. The tempting question gives everything away:

Bad: “Are you responsible for approving software purchases for your team? (Yes / No)” Anyone who wants in answers yes.

The rewrite asks about behaviour, hides the target among realistic distractors, and cannot be reverse-engineered:

Better: “In the last year, which of these have you personally done at work? Booked team travel · Approved a software purchase · Ordered office supplies · Signed off a hiring request.” The right people select the software option among ordinary tasks, and a chooser of all four is a red flag.

After the screener

Screening is your job, not the tool’s. GhostClick does not source or screen participants: you decide who qualifies and recruit them. What it does is the step after. Once you have your qualified list, GhostClick gives each person a private link or emails the invitations, then interviews them by text or voice in seven languages, on their own schedule, and turns the transcripts into analysis. A clean screener up front is what makes those interviews worth running, since the best moderator, human or AI, cannot rescue a study built on the wrong people. The questions you then ask matter as much as who you ask, which is the subject of writing a discussion guide that gets honest answers.
