The Drop-Off Dilemma: Questions That Push Participants Away

One of the big takeaways from our "Maximizing Screener Success" webinar centered around the types of questions that contribute most to unwanted respondent drop-off. While screener length is often cited as a key factor, we know that it’s not just how long a screener is, it’s what’s in it and how it’s asked that can also make or break participation.

PII Questions: The Fast Track to Loss of Trust

Asking for personal identifiable information (PII) such as an email address, phone number, or mailing address too early in the screening process can feel intrusive and damage the rapport that you’re trying to build. Participants may question the necessity of this information before they've even qualified, triggering skepticism and causing drop-off. Instead, consider verifying this information after an individual has qualified or using the tools that you have at your disposal to answer them on your own and in advance.

Example: “Please provide your email, phone, and mailing address.”

Grid Questions: Fatigue in One Glance

While large grid questions might appear efficient on the surface, they’re a well-known driver of screener abandonment. This format often feels visually overwhelming and mentally taxing, requiring more time and effort than participants are willing to give. Even when the content is relevant, the structure alone can prompt respondents to disengage before finishing the screener.

Example: “Review the following products and share whether you currently use them, have used them in the past, have heard of them, evaluated them, or haven’t heard of them.”

Multi-Sentence Open-Ended Questions: High Effort, Low Reward

While open-ended questions can yield rich qualitative data, their placement and phrasing matter. Multi-sentence prompts asking for elaborate responses — particularly early in the screener — can feel like too much work without a clear benefit, leading to early exits. A good gut check: put yourself in the respondent’s shoes and ask whether you could answer the question in just 1–2 sentences. If not, it may be worth rephrasing or simplifying. After all, no one wants to write an essay just to qualify.

Example: “Describe the difference between a venomous and poisonous creature and include three examples of each.”

Questions About Colleagues or Work: Asking for a Favor

When screeners ask participants to provide referrals or information about colleagues, it introduces friction. Not only are respondents reluctant to share others’ information, but these questions also shift the perceived purpose of the screener from evaluation to recruitment, which many find off-putting.

Example: “Who from your company would be a good fit for this research? Please share their name.”

Sensitive Demographic Questions: Stick to Essentials

Demographic questions are incredibly common and often necessary but can be perceived as redundant or even sensitive, especially when they are on topics such as income, gender identity, or sexual orientation. Stick to the essentials during the recruitment process to ensure respondents feel respected and comfortable.

Example: “What is your ____? Age, Sexual Orientation, Gender, Household Income, etc.”

Design with the Participant in Mind

Improving screener performance isn’t just about trimming the question count, it’s about asking smarter, more intentional questions that respect the respondent’s time and experience. By rethinking question types and placement, you can reduce drop-off, increase data quality, and foster better engagement from the very start. Screeners are the gateway to your research — make sure yours opens the door rather than shutting it.
