Add Conditional Logic to Your Strella Question Guide

Show specific guide sections only to qualifying participants by building audience rules based on screener answers or in-call survey responses.

Conditional logic lets you build branched pathways in your question guide so that certain sections are only shown to participants who meet specific criteria. Instead of every participant seeing every question, each person follows the path that matches their profile—making your interviews sharper, more relevant, and more respectful of participants’ time.

What Conditional Logic Does

When you apply audience rules to a section, Strella evaluates each participant’s responses in real time and decides whether to include or skip that section. You can base conditions on:

• Screener Responses — answers participants gave in the pre-interview screening survey.
• In-Call Survey Questions — answers to multiple choice questions (single- or multi-select) that appear earlier in the guide itself.

Conditional logic is applied at the section level. Any questions, tasks, or media nested inside a conditional section will only be shown when all the section’s audience rules are met.

Setting Up Conditional Logic

1. Click the section title

   In the left-hand guide panel, click the title of the section where you want to apply conditions. The section settings will open in the right-hand panel.

2. Toggle on Audience rules

   In the right-hand panel, switch the Audience rules toggle on. A condition builder will appear.

3. Select the question and response

   From the dropdown, choose the screener question or in-call multiple choice question you want to use as your condition. Then select the specific response value that should trigger this section.

   You can add multiple response options to a single condition—for example, show this section to participants who selected either “Weekly” or “Daily” for a frequency question.
4. Add additional conditions

   Click Add condition to layer on more rules. All conditions must be met simultaneously (AND logic) for the section to be shown.

Example: Multi-Condition Audience Rule

Suppose you are researching baby food purchasing behaviour and want to show a specific section only to a narrowly defined segment. Here is how you could build that logic:

Condition 1: Purchase frequency

Question: How often do you shop online for baby food?

Response values: Twice a month or More than twice a month

This ensures participants are active online shoppers, not occasional ones.

Condition 2: Brand awareness

Question: Which of the following baby food brands are you aware of? (multi-select)

Response values: Neither Earth’s Best nor Little Spoon selected

This targets participants who have not encountered these specific brands—useful for unbiased concept testing.

Together, these two conditions create a pathway that is only shown to participants who shop online for baby food at least twice a month and have not heard of Earth’s Best or Little Spoon. Every other participant skips this section entirely.

Make sure the questions you reference in your audience rules are placed before the conditional section in the guide. Strella evaluates conditions based on responses already collected earlier in the interview.
