Why Blocks Matter
Blocks organize a research survey into sections that are easy to scan, test, route, and reuse. In academic survey software, blocks are especially useful for separating consent, screening, treatment materials, outcomes, demographics, and end screens.

Good block structure also makes Flow easier to reason about. Instead of branching between individual questions, you can route respondents between meaningful study sections.
Create Blocks In The Builder
Step 1: Open Block Builder. From Surveys, open the draft and use the Block Builder tab.
Step 1: Open Block Builder
Step 2: Add the first section. Click Add block and name it for the study section, such as Consent or Screening.
Step 2: Add Block
Step 3: Add questions inside the block. Keep related question types together so reviewers can understand the purpose of the section.
Step 3: Question Types
Step 4: Repeat for major sections. Create separate blocks for treatment materials, outcomes, demographics, and end screens.
Step 4: Add More Blocks
Step 5: Open Flow after the block list is stable. Connect blocks with Flow once the structure is clear enough to route and test.

Recommended Block Structure
- Consent block: present study information and ask for consent.
- Screening block: collect eligibility and quota variables.
- Treatment block: show content, stimuli, or randomized materials.
- Outcome block: collect the main dependent variables.
- Demographics block: collect background covariates.
- End Survey blocks: create completion, ineligible, and quota-full endings.

Use Blocks With Flow
After the block order is stable, connect blocks in Flow. Use branching and skip logic for eligibility paths, experimental conditions for treatment assignment, and survey quotas for target response counts.

Reuse Blocks Across Studies
If your lab or class repeats the same consent language, validated scale, screener, or demographic battery, save the block to the Library. Reuse keeps wording consistent across related social science research surveys. See Reusable Research Survey Materials in the Library.
