Filter Cart

The Filter Cart provides a way to query and access data for which you may be interested.  There are multiple places to go query and Add to Filter Cart (Sometimes called Download).  

A few points related to the filter cart are important to understand with the NDA Query/Filter implementation: 

First, the filter cart is populated asyncronously.  So, when you add subjects, sometimes it may take a few minutes to populate.  You can continue to do other things during this time. 

When you are adding your first filter, all data associated with your query will be added to the filter cart (whether it be a collection, a concept, a study, a data structure/elment or subjects). Not all data available for the subjects selected will necessarily be displayed.  For example, if you select the NDA imaging structure image03, and further restrict that query to scan_type fMRI, only fMRI images will appear and only the image03 structure will be available.  However, if you want to see all of the clinical and phenotype, then select, "Find All Subject Data" to see all the data avaialble for those subjects.  

when a secord or third filter is applied, an AND condition is used to determine the subjects that are exist in all filters.  If the subject does not appear in any filter, that subjects data will be excluded from your filter cart. Given the sparcity of data in the NDA, it is possible for no subjects to appear across filters.  If that happens, clear your filter cart, and start over.  

The NDA is looking to enhance query/filtering.  Until additional tools become available, it is best to package more data than you need and then package and download the data and use other tools to further restrict and analyze the data.  If you have any questions on data access, are interested in using avaialble web services or need help accessing data, please contact us for assistance.

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

ados_lac_asomaIntegerRecommendedAmount of Social Overtures/Maintenance of AttentionNulled value range of: 0;1;2;7 to accept outlier data. 0 = Frequent attempts to get or maintain the examiner's attention AND/OR to direct the examiner's attention to objects or actions of interest to the child. 1 = Some attempts at getting, maintaining, or directing the examiner's attention as described above for a rating of 0, but reduced in frequency or the number of contexts used (e.g., only seeks attention to direct examiner's behavior). 2 = Shows relatively little concern as to whether the examiner is paying attention to him/her unless he/she needs help, AND/OR makes few attempts to get, maintain, or direct the examiner's attention. 7 = Unusually frequent, intense, or excessive demands for attention outside structured tasks or questions within the ADOS evaluation, regardless of the social appropriateness of individual behaviors.
ados_lac_cnvstIntegerRecommendedConversationNulled value range of: 0;1;2;3 to accept outlier data. 0 = Conversation flows, building on the examiner's dialogue. This rating requires that much of the child's speech provide both a response to the examiner's speech and some additional talking (not necessarily a question) that builds on what has just been said and allows a response from the examiner (i.e., sequences of at least four elements: examiner opens, child comments, examiner responds, child responds to response). 1 = Speech includes some spontaneous elaboration of the child's own responses for the examiner's benefit OR provides leads for the examiner to follow, but either this is less in amount than would be expected for the child's expressive language level or it is limited in flexibility. 2 = Little reciprocal conversation sustained by the child; may follow his or her own train of thought rather than participate in an interchange; may have some spontaneous offering of information or comments, but little sense of reciprocity. 3 = Little spontaneous communicative speech (although there may be much echoed or noncommunicative speech). This rating can be used to describe children who make some limited, but very few, responses to conversational initiations. by the examiner.
ados_lac_dciigIntegerRecommendedDescriptive, Conventional, Instrumental, or Informational GesturesNulled value range of: 0;1;2;3;8 to accept outlier data. 0 = Spontaneous use of several descriptive gestures. These gestures may be typical or idiosyncratic, but must be communicative.

Grabbing and communicative reaching are coded here. 8 = N/A (e.g., limited by physical disability).
ados_lac_imechIntegerRecommendedImmediate EcholaliaNulled value range of: 0;1;2;3;8 to accept outlier data. 0 = Does not repeat others' speech. (Note: Requires at least five words to code 0 rather than 8.) 1 = Occasional echoing. 2 = Echoing words and phrases regularly, but some spontaneous language, which can be stereotyped. 3 = Speech largely consists of immediate echolalia. 8 = No echolalia noted, but language too limited to judge.
ados_lac_olnel2IntegerRecommendedOverall Level of Non-Echoed LanguageNulled value range of: 0;1;2;3 to accept outlier data. 0 = Non-echoed phrase speech of three or more words per utterance; some grammatical markings, such as plurals or tense. 1 = Speech is primarily two- or three-word utterances, with minimal or no grammatical markings. 2 = Occasional phrases; mostly single words. 3 = Single words only, or no spoken language. 7 = All speech is echoed (immediate or delayed), with or without communicative intent.

ados_lac_saawaIntegerRecommendedSpeech Abnormalities Associated with Autism (Intonation/Volumen/Rhythm/Rate)Nulled value range of: 0;1;2;7;8 to accept outlier data. 0 = Appropriately varying intonation, reasonable volume, and normal rate of speech, with regular rhythm coordinated with breathing. 1 = Little variation in pitch and tone; rather flat or exaggerated intonation, but not obviously peculiar, OR slightly unusual volume, AND/OR speech that tends to be somewhat unusually slow, fast, or jerky. 2 = Speech that is clearly abnormal for ANY of the following reasons: slow and halting; inappropriately rapid; jerky and irregular in rhythm (other than ordinary stutter/stammer); odd intonation or inappropriate pitch and stress; markedly flat and toneless ("mechanical"); consistently abnormal volume. 7 = Stutter or stammer or other fluency disorder (if odd intonation is also present, code 1 or 2 accordingly). 8 = Phrase speech inadequate in frequency or complexity for assessment of intonation/rhythm/rate.
ados_lac_stidw234IntegerRecommendedStereotyped/Idiosyncratic Use of Words (or Phrases)Nulled value range of: 0;1;2;3 to accept outlier data. 0 = Rarely or never uses stereotyped or idiosyncratic words or phrases. 1 = Use of words or phrases tends to be more repetitive than that of most individuals at the same level of complexity, but not obviously odd, OR occasional stereotyped utterances or use of odd words, OR use of phrases in an unusual way, with other flexible spontaneous language, as well. 2 = Often uses stereotyped utterances or odd words or phrases with some other language. 3 = Phrases almost exclusively odd or stereotyped utterances.

Often fidgets, moves about, or gets up out of his/her seat, but is not obviously restless or unusually fidgety. Difficulties in the assessment are not principally due to overactivity. 2 = Hardly remains still at all (not counting the snack). May move around the room in a way that is difficult to interrupt; the level of activity disrupts the assessment. 7 = Underactive.
ados_oab_tandbIntegerRecommendedTantrums, Aggression, Negative or Disruptive BehaviorNulled value range of: 0;1;2 to accept outlier data. 0 = Not upset, disruptive, negative, destructive, or aggressive during ADOS. 1 = Occasional display of mild upset, anger, aggression, negativism, or disruptive behavior to the parent/caregiver or the examiner. 2 = Shows marked or repeated negativism, temper tantrums, or more significant aggression (e.g., hitting, biting others). Loud screaming is included here.
ados_ply_fpwobIntegerRecommendedFunctional Play with ObjectsNulled value range of: 0;1;2;3 to accept outlier data. 0 = Spontaneously plays with a variety of toys in a conventional manner, including appropriate play with several different miniatures/representational toys (e.g., telephone, truck, dishes, materials in the "Birthday Party" activity). Do not include imitations, prompted actions, or pushing the car. 1 = Some spontaneous functional play with at least one miniature/representational toy. Do not include imitations, responses to the examiner's or a parent/caregiver's direct requests (e.g., "Answer the phone"), pushing the car, or use of construction toys. 2 = Plays appropriately with cause-and-effect toys and/or construction toys only, AND/OR pushing the car. This may include imitating a demonstration or imitating more representational play with other toys. 3 = No play with toys or only stereotyped play.
ados_ply_imgcr2IntegerRecommendedImagination/CreativityNulled value range of: 0;1;2;3 to accept outlier data. 0 = Variety of spontaneous, inventive, creative play or activities, including use of doll or figures as agents of action. 1 = Some spontaneous creative or make-believe play, but rather limited in range. May include some use of doll or figures as agents, but less flexible than what would qualify for a rating of 0. 2 = Little spontaneous creative or make-believe play, OR only play that is repetitive or stereotyped in quality. 3 = No creative or inventive play (not even stereotyped or repetitive play). 9 = Cannot be rated for some reason other than that listed above, such as if an examiner makes an error and does not administer a particular ADOS activity.
ados_rsi_arscmIntegerRecommendedAmount of Reciprocal Social CommunicationNulled value range of: 0;1;2;3 to accept outlier data. 0 = Extensive use of verbal or nonverbal behaviors (at whatever level attained) for social interchange (i.e., chat, comments, remarks, or nonverbal behaviors that appear to have reciprocal intent). 1 = Some reciprocal social communication (as described above for a rating of 0 ), but reduced in frequency or amount, or in the number of contexts in which such behaviors occur (regardless of amount of nonsocial talk). 2 = Most communication is either object-oriented (i.e., to ask for things), OR response to questions, OR echolalic, OR concerned with particular preoccupations; little or no social chat or give-and-take. 3 = Little or no communication with examiner or parent/caregiver.
ados_rsi_fedtoIntegerRecommendedFacial Expression Directed to OthersNulled value range of: 0;1;2 to accept outlier data. 0 = Directs a range of appropriate facial expressions to the examiner and/or parent/caregiver in order to communicate affective or cognitive states. 1 = Some direction of facial expressions to the examiner and/or parent/caregiver (e.g., directs only expressions indicating emotional extreme(s) to others, or occasionally directs wider range of expressions). A child who has a limited range of facial expressions, but who directs most of his or her facial expressions to another person, may be rated here. 2 = Does not direct appropriate facial expressions to others.
ados_rsi_oqorpIntegerRecommendedOverall Quality of RapportNulled value range of: 0;1;2;3 to accept outlier data. 0 = Comfortable interaction between the child and examiner that is appropriate to the context of the ADOS assessment. 1 = Interaction sometimes comfortable, but not sustained (e.g., sometimes feels awkward or stilted, or the child's behavior seems mechanical or slightly inappropriate). 2 = One-sided or unusual interaction resulting in a consistently mildly uncomfortable session or a session that would have been difficult if the examiner had not continuously modified the structure of the situation beyond the standard activities in the ADOS evaluation. 3 = The child shows minimal regard for the examiner, OR the session is markedly uncomfortable for a significant proportion of the time.
ados_rsi_qscloIntegerRecommendedQuality of Social OverturesNulled value range of: 0;1;2;3 to accept outlier data. 0 = Effectively uses nonverbal and verbal means to make clear social overtures to the examiner or the parent/caregiver. The overtures must be appropriate to immediate contexts. 1 = Slightly unusual quality of social overtures. Assign this rating if overtures are restricted to personal demands or related to strong interests, but with some attempt to involve the examiner or the parent/caregiver in those interests. 2 = Overtures often lack integration into context AND/OR social quality. Assign this rating if there are some clearly inappropriate overtures, even if there are other overtures. 3 = No social overtures of any kind.
ados_rsi_qsclrIntegerRecommendedQuality of Social ResponseNulled value range of: 0;1;2;3 to accept outlier data. 0 = Shows a range of appropriate responses that are varied according to immediate social situations and presses. 1 = Shows responsiveness to most social situations, but somewhat limited, socially awkward, inappropriate, inconsistent, or consistently negative. 2 = Odd, stereotyped responses, or responses that are restricted in range or inappropriate to the context. 3 = Minimal or no response to the examiner's attempts to engage the child.
ados_rsi_rspjaIntegerRecommendedResponse to Joint AttentionNulled value range of: 0;1;2;3 to accept outlier data. 0 = Uses the orientation of the examiner's eyes and face alone as a cue to look toward the target, without the need for pointing. The child must follow the examiner's gaze and turn his/her face or eyes in the direction of the target after watching the examiner do so; he/she does not actually have to catch sight of the target. 1 = Responds to the examiner's pointing by looking at or toward the target. 2 = Looks at the target when it is activated or placed directly in front of himlher, but does not make use of the examiner's gaze or pointing in order to locate the target from a distance. 3 = No interest or awareness of the target. If it is not possible to get the child's attention in order to direct it in five attempts, assign this rating.
ados_rsi_rsptn2IntegerRecommendedResponse to nameNulled value range of: 0;1;2;3 to accept outlier data. 0 = Looks toward the examiner and makes eye contact immediately on at least one of the first two clear presses made by the examiner (i.e., name only is called). 1 = Makes eye contact with the examiner immediately on the examiner's third or fourth press of name only OR looks toward the parent/caregiver and makes eye contact immediately for the first or second press of name only. 2 = Does not make eye contact with either the examiner or the parent/caregiver after his/her name is called in four attempts, but shifts gaze briefly (no eye contact), OR looks at least once when an interesting or familiar vocalization or verbalization is made (e.g., tongue clucking; I'm gonna get you"). 3 = Does not look toward either the examiner or the parent/caregiver after any purely verbal or vocal attempt to get attention.
ados_rsi_seiit234IntegerRecommendedShared Enjoyment in InteractionNulled value range of: 0;1;2;8 to accept outlier data. 0 = Shows definite and appropriate pleasure in interactive participation or conversation during more than one task or conversational topic. 1 = Shows some appropriate pleasure in the examiner's actions, OR shows definite pleasure during one interaction. 2 = Shows little or no expressed pleasure in interaction. May show pleasure in his/her own actions or part of the conversation, but not in the examiner's behavior or in interaction. 8 = Not scorable due to little or no interaction, or for other reasons.
ados_rsi_showgIntegerRecommendedShowingNulled value range of: 0;1;2 to accept outlier data. 0 = Spontaneously shows toys or objects throughout the ADOS evaluation by holding them up or placing them in front of others and using eye contact with or without vocalization. 1 = Shows toys or objects in a partial or inconsistent manner (e.g., holds them up and/or places them in front of others without coordinated eye contact, looks from an object in his/her hands to another person without clearly orienting it toward that person, or shows objects as described above for a rating of 0 on one occasion only). 2 = Does not show objects to another person.
ados_rsi_spijaIntegerRecommendedSpontaneous Initiation of Joint AttentionNulled value range of: 0;1;2 to accept outlier data. 0 = Uses clearly integrated eye contact to reference an object that is out of reach by looking at the object, then at the examiner or the parent/caregiver, and then back to the object. Eye contact may be coordinated with pointing and/or vocalization. One clear example of an attempt to draw another person's attention to an object (i.e., more than just referencing) is sufficient for this rating. 1 = Partially references an object that is clearly out of reach. May spontaneously look and point to the object and/or vocalize, but does not coordinate either of these with looking at another person, OR may look at an object and then look at or point to the examiner or the parent/caregiver, but not look back at the object. 2 = No approximation of spontaneous initiation of joint attention in order to reference an object that is out of reach.
ados_rsi_uneycIntegerRecommendedUnusual Eye Contact0 = Appropriate gaze with subtle changes meshed with other communication. 2 = Uses poorly modulated eye contact to initiate, terminate, or regulate social interaction. 3 = Uses poorly modulated eye contact to initiate, terminate, or regulate social interaction AND frequently actively avoids eye contact (e.g., by turning away, pushing away, closing eyes).
ados_sar_hfocmIntegerRecommendedHand and Finger and Other Complex MannerismsNulled value range of: 0;1;2 to accept outlier data. 0 = None. 1 = Very brief or rare hand and finger mannerisms or complex mannerisms, OR mannerisms not as clear as specified below for a rating of 2. 2 = Definite finger flicking or twisting, ANP/OR, hand or other mannerisms or stereotypes.
ados_sar_sfijbIntegerRecommendedSelf-Injurious BehaviorNulled value range of: 0;1;2 to accept outlier data. 0 = No attempts to harm self. 1 = Dubious or possible self-injury, and/or rare but clear self-injury (e.g., one clear example of biting at own hand or arm, pulling own hair, slapping own face, or banging own head). 2 = More than one clear example of self-injury, such as head banging, face slapping, hair pulling, or self-biting.
ados_sar_urisbIntegerRecommendedUnusually Repetitive Interests or Stereotyped BehaviorsNulled value range of: 0;1;2;3 to accept outlier data. 0 = No repetitive or stereotyped behaviors during the ADOS evaluation. 1 = An interest or behavior that is repetitive or stereotyped to an unusual degree, including an intense interest in a particular toy or object, a definite interest in an unusual object or activity (odd for the child's level of motor skill), an unusually routinized activity, or a clear interest in a part of an object. This interest or behavior occurs in conjunction with several other activities and does not prevent the child from completing any ADOS activities. 2 = Clearly repetitive or stereotyped interests and/or behaviors, as described above. These behaviors may form a substantial minority of the child's interests and spontaneous behaviors and may interfere with the child's ability to complete ADOS activities, but it is possible for his or her attention to be directed to other objects or activities, at least momentarily. 3 = Repetitive or stereotyped interests and/or behaviors, as described above, form the majority of the child's interests, AND/OR attempts to direct his or her attention to other objects or activities are met with significant resistance and/or distress.
ados_sar_usipmIntegerRecommendedUnusual Sensory Interest in Play Material PersonNulled value range of: 0;1;2 to accept outlier data. 0 = No sniffing, repetitive touching, feeling of texture, licking or biting (not mouthing), interest in the repetition of or unusually strong reactions to certain sounds, or unusual or prolonged visual examination. 1 = Occasional unusual sensory interests or responses, OR not as clear as specified below for a rating of 2. 2 = Definite interest in nonfunctional elements of play materials, OR sensory examination of himself/herself or others on more than one occasion, OR persistent unusual sensory response to several materials or events.

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.
