Questionnaires provide detailed control over order, presentation, phraseology and grouping to allow coherent, consistent data collection. If the element is present, it must have either a @value, an @id, or extensions An absolute URI that is used to identify this questionnaire when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this questionnaire is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the questionnaire is stored on different servers. A formal identifier that is used to identify this questionnaire when it is represented in other formats, or referenced in a specification, model, design or an instance. The identifier that is used to identify this version of the questionnaire when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the questionnaire author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. Indicates the mechanism used to compare versions to determine which is more current. A natural language name identifying the questionnaire. This name should be usable as an identifier for the module by machine processing applications such as code generation. A short, descriptive, user-friendly title for the questionnaire. The URL of a Questionnaire that this Questionnaire is based on. The current state of this questionnaire. A Boolean value to indicate that this questionnaire is authored for testing purposes (or education/evaluation/marketing) and no version of this resource will ever be intended for genuine usage. The types of subjects that can be the subject of responses created for the questionnaire. The date (and optionally time) when the questionnaire was last significantly changed. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the questionnaire changes. The name of the organization or individual responsible for the release and ongoing maintenance of the questionnaire. Contact details to assist a user in finding and communicating with the publisher. A free text natural language description of the questionnaire from a consumer's perspective. The content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, ...) or may be references to specific programs (insurance plans, studies, ...) and may be used to assist with indexing and searching for appropriate questionnaires. A legal or geographic region in which the authority that maintains the resource is operating. In general, the jurisdiction is also found in the useContext. The useContext may reference additional jurisdictions because the defining jurisdiction does not necessarily limit the jurisdictions of use. Explanation of why this questionnaire is needed and why it has been designed as it has. A copyright statement relating to the questionnaire and/or its contents. Copyright statements are notices of intellectual property ownership and can include restrictions on the use and publishing of the questionnaire. A short string (<50 characters), suitable for inclusion in a page footer that identifies the copyright holder, effective period, and optionally whether rights are restricted. (e.g. 'All rights reserved', 'Some rights reserved'). The date on which the resource content was approved by the publisher. Approval happens once when the content is officially approved for usage. The date on which the resource content was last reviewed. Review happens periodically after approval but does not change the original approval date. The period during which the questionnaire content was or is planned to be in active use. An identifier for this collection of questions in a particular terminology such as LOINC. A particular question, question grouping or display text that is part of the questionnaire. A structured set of questions intended to guide the collection of answers from end-users. Questionnaires provide detailed control over order, presentation, phraseology and grouping to allow coherent, consistent data collection. An identifier that is unique within the Questionnaire allowing linkage to the equivalent item in a QuestionnaireResponse resource. This element is a URI that refers to an [ElementDefinition](elementdefinition.html) or to an [ObservationDefinition](observationdefinition.html) that provides information about this item, including information that might otherwise be included in the instance of the Questionnaire resource. A detailed description of the construction of the URI is shown in [Comments](questionnaire.html#definition), below. A terminology code that corresponds to this group or question (e.g. a code from LOINC, which defines many questions and answers). A short label for a particular group, question or set of display text within the questionnaire used for reference by the individual completing the questionnaire. The name of a section, the text of a question or text content for a display item. The type of questionnaire item this is - whether text for display, a grouping of other items or a particular type of data to be captured (string, integer, Coding, etc.). A constraint indicating that this item should only be enabled (displayed/allow answers to be captured) when the specified condition is true. Controls how multiple enableWhen values are interpreted - whether all or any must be true. Indicates if and how items that are disabled (because enableWhen evaluates to 'false') should be displayed. An indication, if true, that the item must be present in a "completed" QuestionnaireResponse. If false, the item may be skipped when answering the questionnaire. An indication, if true, that a QuestionnaireResponse for this item may include multiple answers associated with a single instance of this item (for question-type items) or multiple repetitions of the item (for group-type items). An indication, when true, that the value cannot be changed by a human respondent to the Questionnaire. The maximum number of characters that are permitted in the answer to be considered a "valid" QuestionnaireResponse. For items that have a defined set of allowed answers (via answerOption or answerValueSet), indicates whether values *other* than those specified can be selected. A reference to a value set containing a list of values representing permitted answers for a question. One of the permitted answers for the question. One or more values that should be pre-populated in the answer when initially rendering the questionnaire for user input. Text, questions and other groups to be nested beneath a question or group. A structured set of questions intended to guide the collection of answers from end-users. Questionnaires provide detailed control over order, presentation, phraseology and grouping to allow coherent, consistent data collection. The linkId for the question whose answer (or lack of answer) governs whether this item is enabled. Specifies the criteria by which the question is enabled. A value that the referenced question is tested using the specified operator in order for the item to be enabled. If there are multiple answers, a match on any of the answers suffices. If different behavior is desired (all must match, at least 2 must match, etc.), consider using the enableWhenExpression extension. A structured set of questions intended to guide the collection of answers from end-users. Questionnaires provide detailed control over order, presentation, phraseology and grouping to allow coherent, consistent data collection. A potential answer that's allowed as the answer to this question. Indicates whether the answer value is selected when the list of possible answers is initially shown.
