Eating Disorder Examination Questionnaire (EDE-Q 6.0)
-----------------------------------------------------

.. include:: include_data_collection_plus_local_upgrade.rst

The EDE-Q is the self-report questionnaire version of the Eating Disorder
Examination (EDE) interview. There are 28 questions, and four subscales. To
calculate a subscale score, calculate the arithmetic mean of the relevant rated
items in the scale (listed below). The overall 'global' score is the arithmetic
mean of the four subscales.

In our implementation all applicable questions are mandatory so all items will
have been rated.

.. todo:: EDE-Q: no longer all mandatory? Mark which aren't, if so.
