NDAR provides a single access to de-identified autism research data. For permission to download data, you will need an NDAR account with approved access to NDAR or a connected repository (AGRE, IAN, or the ATP). For NDAR access, you need to be a research investigator sponsored by an NIH recognized institution with federal wide assurance. See Request Access for more information.

Selected Filters
No filters selected

The filters you have selected from various query interfaces will be stored here, in the 'Filter Cart'. The database will be queried using filters added to your 'Filter Cart', when multiple filters are defined, each will be executed using 'AND' logic, so with each filter that is applied the result set gets smaller.

From the 'Filter Cart' you can inspect each of the filters that have been defined, and you also have the option to remove filters. The 'Filter Cart' itself will display the number of filters applied along with the number of subjects that are identified by the combination of those filters. For example a GUID filter with two subjects, followed by a GUID filter for just one of those subjects would return only data for the subject that is in both GUID filters.

If you have a question about the filter cart, or underlying filters please contact the help desk at The NDA Help Desk

genderString20RequiredSex of the subjectM;FM = Male; F = Female
cas_1IntegerRecommendedPsychic Tension (care should be taken to distinguish tension from muscular tension -- see next item)0::44 = Very marked and distressing feeling of being on edge 'keyed up', 'wound up' or 'nervous' which persists with little change throughout the waking hours. ;3 = As above, but with some fluctuation of severity during the course of the day. ;2 = A definite experience of being tense which is sufficient to cause some, although not severe, distress. ;1 = A slight feeling of being tense which does not cause distress. 0 = No feeling of being tense apart from the normal degree of tension experienced in response to stress and which is acceptable as normal for the population.
cas_2IntegerRecommendedAbility to Relax (muscular tension)0::44 = The experience of severe tension throughout much of the bodily musculature which may be accompanied by such symptoms as pain, stiffness, spasmodic contractions, and lack of control over movements. The experience is present throughout most of the waking day and there is no ability to produce relaxation at will. ;3 = As above, but the muscular tension may only be experienced in certain groups of muscles and may fluctuate in severity throughout the day. ;2 = A definite experience of muscular tension in some part of the musculature sufficient to cause some, but not severe, distress. ;1 = Slight recurrent muscular tension of which the patient is aware but which does not cause distress. Very mild degrees of tension headache or pain in other groups of muscles should be scored here. ;0 = No subjective muscular tension or of such degree which, when it occurs, can easily be controlled at will.
cas_3IntegerRecommendedStartle Response (hyperarousability)0::44 = Unexpected noise causes severe distress so that the patient may complain in some such phrase as "I jump out of my skin". Distress is experienced is psychic and somatic modalities so that, in addition to the experience of fright, there is muscular activity and autonomic symptoms such as sweating or palpitation. ;3 = Unexpected noise causes severe distress in psychic or somatic, but not in both modalities. ;2 = Unexpected noise causes definite but not severe distress. 1 = The patient agrees that he is slightly 'jumpy' but is not distressed by this. ;0 = The degree of startle response is entirely acceptable as normal for the population.
cas_4IntegerRecommendedWorrying (The assessment must take into account the degree to which worry is out of proportion to actual stress)0::44 = The patient experiences almost continuous preoccupation with painful thoughts which cannot be stopped voluntarily and the distress is quite out of proportion to the subject matter of the thoughts. ;3 = As above, but there is some fluctuation in intensity throughout the waking hours and the distressing thoughts may cease for an hour or two, especially if the patient is distracted by activity requiring his attention. ;2 = Painful thoughts out of proportion to the patient's situation keep intruding into consciousness but he is able to dispel or dismiss them. ;1 = The patient agrees that he tends to worry a little more than necessary about minor matters ;0 = The tendency to worry is accepted as being normal for the population ; for instance even marked worrying over a severe financial crisis or unexpected illness in a relative should be scored as 0 if it is judged to be entirely in keeping with the degree of stress.
cas_5IntegerRecommendedApprehension0::44 = The experience is that of being on the brink of some disaster which cannot be explained. The experience need not be continuous and may occur in short bursts several times a day.; 3 = As above, but the experience does not occur more than once a day.; 2 = A sensation of groundless apprehension of disaster which is not severe although it causes definite distress. The patient may not use strong terms such as "disaster" or "catastrophe" but may express his experience in some such phrase as "I feel as if something bad is about to happen".; 1 = A slight degree of apprehensiveness of which the patient is aware but which does not cause distress.; 0 = No experience of groundless anticipation of disaster.
cas_6IntegerRecommendedRestlessness0::44 = The patient is unable to keep still for more than a few minutes and engages in restless pacing or other purposeless activity. ;3 = As above, but he is able to keep still for an hour or so at time. ;2 = There is a feeling of "needing to be on the move" which causes some, but not severe, distress. ;1 = Slight experience of restlessness which causes no distress. 0 = Absence of restlessness.

Data Structure

This page displays the data structure defined for the measure identified in the title and structure short name. The table below displays a list of data elements in this structure (also called variables) and the following information:

  • Element Name: This is the standard element name
  • Data Type: Which type of data this element is, e.g. String, Float, File location.
  • Size: If applicable, the character limit of this element
  • Required: This column displays whether the element is Required for valid submissions, Recommended for valid submissions, Conditional on other elements, or Optional
  • Description: A basic description
  • Value Range: Which values can appear validly in this element (case sensitive for strings)
  • Notes: Expanded description or notes on coding of values
  • Aliases: A list of currently supported Aliases (alternate element names)
  • For valid elements with shared data, on the far left is a Filter button you can use to view a summary of shared data for that element and apply a query filter to your Cart based on selected value ranges

At the top of this page you can also:

  • Use the search bar to filter the elements displayed. This will not filter on the Size of Required columns
  • Download a copy of this definition in CSV format
  • Download a blank CSV submission template prepopulated with the correct structure header rows ready to fill with subject records and upload

Please email the The NDA Help Desk with any questions.

Chart Help

Filters enable researchers to view the data shared in NDA before applying for access or for selecting specific data for download or NDA Study assignment. For those with access to NDA shared data, you may select specific values to be included by selecting an individual bar chart item or by selecting a range of values (e.g. interview_age) using the "Add Range" button. Note that not all elements have appropriately distinct values like comments and subjectkey and are not available for filtering. Additionally, item level detail is not always provided by the research community as indicated by the number of null values given.

Filters for multiple data elements within a structure are supported. Selections across multiple data structures will be supported in a future version of NDA.
