Open text questions allow participants to respond in their own words. They capture nuances, explanations, and insights that structured questions can’t provide.

When to Use Open Text

Open text questions excel at capturing:
  • Reasons and motivations: Why participants feel or behave a certain way
  • Detailed feedback: Specific suggestions and complaints
  • Unexpected insights: Ideas you hadn’t considered
  • Personal stories: Experiences and examples
  • Clarification: Follow-up to structured questions
Example:
“What could we do to improve your experience with our product?” [Text area for response]

Types of Open Text Questions

Short Answer

Brief responses, typically one line or sentence. Use for:
  • Specific information (names, locations)
  • Brief explanations
  • Quick feedback
Example:
“What brand do you use most often?”

Long Answer (Paragraph)

Extended responses with more detail. Use for:
  • Detailed explanations
  • Stories and experiences
  • Comprehensive feedback
Example:
“Please describe your most recent experience with our customer service team.”

Creating Open Text Questions

1

Add an Open Text Question

Use AI chat (“Add an open-ended question about…”) or add manually.
2

Write the Question

Be specific about what you want to learn. Vague questions get vague answers.
3

Add Instructions (Optional)

Guide participants on expected detail level or specific aspects to address.
4

Configure Settings

Set required/optional, character limits, and display options.

Writing Effective Open Text Questions

Be Specific

Vague questions get vague answers. Specific questions get useful data.
VagueSpecific
”Any feedback?""What one thing would most improve this product?"
"Describe your experience""Describe a recent situation where this product helped you solve a problem"
"What do you think?""What concerns, if any, do you have about switching to this service?”

Provide Context

Reference previous questions or set the scene. Example:
“You mentioned you were dissatisfied with the delivery time. Please tell us more about that experience.”

Use Prompting Techniques

TechniqueExample
Completion”The best thing about this product is…”
Comparison”Compared to other brands, this one…”
Scenario”Imagine you’re recommending this to a friend. What would you say?”
Negative framing”What would make you stop using this product?”

Guide Without Leading

Provide structure without suggesting answers. Good: “What factors influenced your decision?” Leading: “How much did the great reviews influence your decision?”

Open Text Best Practices

Place strategically. Put open text questions after related structured questions. Participants have more context to draw from.
Don’t overuse. Too many open text questions cause fatigue. Use them selectively for key insights.
Keep instructions brief. Long instructions overwhelm participants. A sentence or two is enough.
Consider making optional. Required long-form questions may get low-quality responses if participants have nothing to say.

Setting Expectations

Character or Word Limits

You can set minimum or maximum lengths:
  • Minimum: Ensures some level of detail
  • Maximum: Keeps responses manageable
Be reasonable—very high minimums lead to padding and filler text.

Example Responses

Sometimes providing an example helps:
“Example: ‘I love the quick checkout process, but wish there were more payment options.’”
Use sparingly to avoid anchoring participants to your example.

Analyzing Open Text Responses

Open text questions require qualitative analysis:

AI-Powered Analysis

Deepfield’s AI can:
  • Identify themes and patterns
  • Group similar responses
  • Extract key quotes
  • Summarize findings

Manual Review

For deeper insights:
  • Read through all responses
  • Tag or code responses by theme
  • Look for patterns and outliers
  • Extract compelling quotes

Integration with Reports

Open text responses appear in your analysis reports with:
  • Theme categorization
  • Representative quotes
  • Citation links to full responses

Common Open Text Patterns

Follow-Up to Rating

After a satisfaction question:
“What is the main reason for your satisfaction rating?”

Improvement Questions

“If you could change one thing about [product], what would it be and why?”

Comparison Questions

“How does [product] compare to others you’ve tried? What makes it better or worse?”

Future-Looking Questions

“What features would you like to see added in the future?”

Final Comments

At the end of a study:
“Is there anything else you’d like to share about your experience?”

Common Mistakes

Answering open text questions takes effort. Limit to 3-5 per study unless it’s specifically qualitative research.
“Tell us about your experience” is too broad. Guide participants on what specifically to address.
“Why do you love this feature?” assumes they love it. Use neutral phrasing.
Don’t ask open text questions in isolation. Build on previous structured questions.
Forcing detailed responses when participants have little to say produces poor quality data.

Open Text vs. Video/Audio

Participant preferenceSome prefer writingSome prefer speaking
Consider offering both options or using video/audio for your most important qualitative questions.
