SURVEY CREATOR - YES/NO BOOLEAN QUESTIONS

Summary & Best Practices

In Survey Creator, the Yes/No Boolean question is a specialized, fast-response component found in your Toolbox. It presents a simple, binary toggle switch or a pair of buttons representing exactly two mutually exclusive choices (typically "Yes" and "No", or "True" and "False"). It is the most streamlined way to collect a quick affirmative or negative response. However, keep in mind that, the response may be too easily or accidentally changed for some survey respondents.

When to Use It

• Strict Binary Decisions: When a question has only two possible outcomes with no gray area (e.g., "Are you 18 years old or older?").
• Qualifying Filters (Screeners): Perfect as the very first question in a survey to filter out respondents who do not meet the criteria for the rest of the study.
• Consent Toggles: Ideal for quick opt-in forms, such as "Do you agree to receive email updates?"

When NOT to Use It

• Shades of Agreement: If there is any chance a user might want to say "Maybe," "Sometimes," or "Not Applicable," do not use a Boolean question. Use a Radio Button Group so you can include those middle-ground options.
• Evaluations or Ratings: Do not use a yes/no boolean question to measure the degree to which a participant experienced a symptom, agreed with a statement, or evaluated an intervention. Instead, use a Rating Scale to capture the intensity, frequency, severity, or level of agreement along an ordered continuum, such as “Not at all” to “Extremely” or “Strongly disagree” to “Strongly agree.”
• Multi-Select Contexts: If a user needs to confirm that multiple items from a list apply to them, use Checkboxes instead.

Property Grid

The General properties define the question’s identity, content, behavior, and data connections. You can specify the question name (backend value), title (survey label), and description; control whether the question is visible, read-only, or required; and add a comment box for additional respondent feedback. You can also adjust the Yes/No response option labels and orders in this category.

Layout properties control how the question appears on the survey page. They let you place the question on a new line, hide its number, and determine whether it is collapsed or expanded. You can also adjust the alignment of the question title, description, and error messages, as well as control the question’s indentation and width. The settings also include the number of columns used to display the answer choices, allowing you to present them vertically or across multiple columns.

The Conditions properties control the question’s behavior based on survey responses or other conditions. You can determine when the question becomes visible, read-only, or required; set or reset its value; and define default values using expressions. These settings also allow you to hide the question when no choices are available and control when individual choices are visible or selectable.

The Data properties determine how responses are stored, evaluated, and used throughout the survey. They allow you to assign a join identifier, set a default response of Yes/True or No/False, and define or clear the correct answer for scoring or knowledge checks. You can also choose whether dynamic text displays the user-facing labels, such as “Yes” or “No,” and whether a response is cleared when the question becomes hidden. The settings further let you specify the exact values stored in the data set for True and False responses, keeping stored data separate from the labels shown to participants.

The Validation properties ensure that respondents provide acceptable answers. You can add validation rules to check whether responses meet specific requirements, such as a required format or value range. This section also allows you to customize the error message displayed when a required question is left unanswered.
