Conditional notifications let you configure a prompt to only fire if a participant’s previous answer meets a specific condition. This is an advanced feature for creating adaptive, branching study flows.
How It Works
Each prompt can have an optional notify condition with four fields:
| Field | Description |
|---|
| Source Type | What kind of question to check: prompt (another prompt in the quest) or onboarding (an onboarding question) |
| Source ID | Which specific prompt or onboarding question to evaluate |
| Operator | The comparison operator |
| Value | The value to compare the participant’s answer against |
Available Operators
| Operator | Label | Description |
|---|
eq | Equals | Exact match (case-insensitive) |
neq | Not equals | Does not match |
gt | Greater than | Numeric: answer > value |
gte | Greater than or equal | Numeric: answer ≥ value |
lt | Less than | Numeric: answer < value |
lte | Less than or equal | Numeric: answer ≤ value |
Source Options
The source list is built from:
- All other prompts in the same quest (excluding the current prompt)
- All onboarding questions in the quest
This means you can use either a participant’s ongoing prompt responses or their initial onboarding answers to determine whether a follow-up prompt should fire.
Examples
Follow-up on Poor Sleep
Only ask about caffeine if the participant reported sleeping poorly.
| Field | Value |
|---|
| Source Type | prompt |
| Source | ”Did you sleep well last night?” (yesno prompt) |
| Operator | eq |
| Value | No |
High Stress Follow-up
Only ask about stress coping strategies if stress rating is high.
| Field | Value |
|---|
| Source Type | prompt |
| Source | ”Rate your stress level (1–10)” (numberRange prompt) |
| Operator | gte |
| Value | 7 |
Based on Onboarding Answer
Only send exercise prompts to participants who indicated they exercise regularly.
| Field | Value |
|---|
| Source Type | onboarding |
| Source | ”Do you exercise regularly?” (yesno onboarding question) |
| Operator | eq |
| Value | Yes |
Tips
Conditional notifications are evaluated at notification time. The condition checks the participant’s most recent response to the source question.
A prompt with a conditional notification will never fire if the source question hasn’t been answered yet. Make sure the source prompt is scheduled before the conditional prompt.
- Use conditions to reduce participant burden — only ask follow-up questions when relevant
- Combine with the scheduling system to create sophisticated adaptive study protocols
- You can only set one condition per prompt
