# SDC: StructureDefinition-sdc-questionnaire-adapt-intro

### Scope and Usage

This profile inherits from the base [Questionnaire]({{site.data.fhir.path}}questionnaire) It identifies core elements and extensions that must be supported and highlights other elements that, while not required, may be relevant to the adaptive questionnaire use-case. Further information on how this use-case is implemented as well as guidance on the elements and extensions included in the profile can be found on the [Adaptive Forms](/sdc-adaptive) page.

This profile is only used within an adaptive QuestionnaireResponse. For an adaptive Questionnaire found on a registry or otherwise returned as a 'candidate' for completion, refer to the [Adaptive Questionnaire Search](/sdc-structuredefinition-sdc-questionnaire-adapt-srch-intro) profile.
