FREQUENTLY ASKED QUESTIONS


What does the Package measure?
The Package measures vision (visual acuity and contrast sensitivity); cortical auditory processing; neuropsychological outcomes (cognition, expressive and receptive language, fine and gross motor, behaviour, attention and social-emotional reactivity) and sleep (sleep efficiency, latency and fragmentation; circadian rhythm and daytime physical activity). 

How long does does the Package take to administer?
The Package takes 45 minutes to administer (vision = 5 minutes, the INTER-NDA = 15 minutes, cortical auditory processing = 10 minutes and sleep = 5 minutes). 

Can the Package/INTER-NDA be administered by clinicians and specialists?
Yes, the Package has been designed so that non-clinicians can administer the Package to the same degree of protocol adherence and reliability as clinicians and specialist healthcare staff. Please contact us for further details about data supporting this.

What is the age range that the Package is suitable to be used for?
The INTER-NDA was designed for use in the 22 to 26 months age group, but contains items from 18 to 36 months. The vision, cortical auditory processing and sleep tests are independent and can be used across all age groups. 

Can the Package be used in all countries?
Yes, the Package was designed to be free from cultural biases and cultural customisation is an integral part of the training process. 

How much does the Package cost?
For non-commercial purposes, the Package does not have a fee per use. To find out about equipment costs, please contact us. For commercial purposes, the Package will be costed depending upon the nature of the usage. 

How is the EEG data analysed?
The EEG data is analysed using a specially developed and validated signal processing pipeline. 

How is the actigraphy data analysed?
The actigraphy data is analysed in two phases. In the pre-processing phase, the data is cleaned, checked for quality and selected using a standardised pre-processing protocol. In the processing phase, the selected data is processed in the Actiwatch software. 

What is the NeuroApp?
The NeuroApp is a tablet based application for data collection, test administration and data upload. It has integrated quality checks to prevent multiple entries and missing data and facilitates real time upload of data to our centralised database. 

What are the product specifications of the tablet required for the NeuroApp?
The NeuroApp is an iOS application and hence the tablet needs to be iOS compatible.

Who provides the data server capacity for the NeuroApp?
The data server capacity is provided by the University of Oxford via the INTER-NDA consortium.

What does the INTER-NDA measure?
The INTER-NDA measures cognition, expressive and receptive language, fine and gross motor, behaviour, attention and social-emotional reactivity

How long does the INTER-NDA take to administer?
The INTER-NDA takes 13 to 17 minutes to administer. 

What is the age range that the INTER-NDA was designed for?
The INTER-NDA was designed for use in the 22 to 26 months age group, but contains items from 18 to 36 months. 

Has the INTER-NDA been validated?
The INTER-NDA has been validated against the BSID-III at 24 months. Please contact us for further details. 

Is the INTER-NDA diagnostic of early developmental problems?
The INTER-NDA is a screening test and is not diagnostic of early developmental problems. 

Does the INTER-NDA score give a developmental age for the child?
The INTER-NDA does not give a developmental age for the child as it was designed to be a one-off screening assessment at 22 to 26 months. 

Can the INTER-NDA be used in all countries?
Yes, the INTER-NDA can be used anywhere as it was designed to be free from cultural biases. 

Can the INTER-NDA be used in both high and low income settings?
Yes,  the INTER-NDA can be used in both high and low income settings. It was designed to be free from the influence of culture and education on the child. 
 
Can the INTER-NDA kit be sourced locally?
Yes, the INTER-NDA kit items can be sourced locally. Please contact us for a list of these items. 

Can data be collected on paper forms?
Yes, if you do not wish to use the NeuroApp, you can collect data on paper forms. Please click here for copies of these or contact us. 

What languages are the INTER-NDA available in?
The INTER-NDA is available in English, Spanish, French and Italian. Please click here for translated versions of the INTER-NDA.

What is the difference between the Package and the INTER-NDA?
The INTERGROWTH-21st Project Neurodevelopment Package refers to a group of 4 tests measuring neuropsychological outcomes, vision, cortical auditory processing and sleep in 2 year olds. It takes 45 minutes to administer. The test that measures neuropsychological outcomes, and which is one of the four parts of the package, is called the INTER-NDA. It takes 15 minutes to administer and measures cognition, motor skills, language, behaviour, social-emotional reactivity and attention. The INTER-NDA is therefore a part of the Package.

What is the INTER-NDA consortium?
The INTER-NDA consortium is a group of subscribers to the methodology and ideology of the INTER-NDA Package. The consotrium dataset is a pooled, anonymised dataset of vision, INTER-NDA, EEG and sleep data from various parts of the world. 

How do I access consortium data?
You will need to complete a consortium data agreement with the University of Oxford which includes data access request forms. Please contact us for further information.
 
Can I access only specific aspects of consortium data; for example only EEG data?
Yes, you can access one or all components of the Package. You cannot, however, access data from a particular study as all data are anonymised. 

How do I use the Package in my research project?
Please read our manuals and the description of the INTER-NDA methodology to ensure that the Package is suitable for your project. If you think it is, please contact us to arrange a training session. 
 
How do I use the Package in my clinic?
Please read our manuals and the description of the INTER-NDA methodology to ensure that the Package is suitable for your clinic and for your patients. If you think it is, please contact us to arrange a training session. 

What do mothers think about the Package?
To date, in our experience, mothers find the Package very informative. They enjoy seeing their children complete the tasks. 

How do children react to the Package?
Children find the Package entertaining. They are happy to complete the tasks which are organised into a play-based sequence. As the assessments are short, the children do not get tired or bored before completion.  In our experience, most children are happy to co-operate if the vision tests are completed before the INTER-NDA as it is an un-intrusive test and can be used to build a rapport with the child. 

is there a version of the INTER-NDA for younger children?
Yes, we have developed a 12 month tool to measure cognition, languauge, motor, behaviour, attention, social-emotional reactivity, empathy and executive function in 10 - 14 month olds. This tool, the OX-NDA, takes 20 minutes to administer. It has been evaluated against the BSID-III in Pelotas, Brazil (results in progress). Please contact Dr Michelle Fernandes for further information.
