The IES has an internal consistency of 0.65 which increases to 0.82 if one of the 8 items is removed, but later publications are based on either the eight item version or a 10-item version [ 42, 87] for which no published psychometric validation evidence could be found.
It was evident that most studies relied on either one item or two items to collect data on "total time spent on screens" and that these data related to TV watching, or computer use, or video game playing, or a combination of these.
We scored all survey items on either a 7-point scale of statement accuracy (1- Highly inaccurate to 7- Highly accurate) or a 5-point scale of frequency (1- Never to 5- Always).
Lesions in either the medial prefrontal cortex have no effect on either single item recognition or object location memory, and so the type of information processing that the medial prefrontal cortex is engaged in appears distinct from that of either the perirhinal cortex or hippocampus.
Because patients could only answer either the item on ability to book 'urgent' (within 2 days) appointments or the item on ability to book 'routine' (after 2 days or later) appointments, these two items were combined into one variable: 'ability to get an appointment'.
Secondly the content of these measures relies either on literature, item reduction using item pool and expert panels [ 7, 8, 10, 14], although it is generally recommended that the content of self-reported measures of well-being and quality of life be developed in the end-user [ 15, 16].
In addition, we manipulated strength of the positive after-image by using either white items on a black background, or red items on an isoluminant gray background (Fig. 1a/b).
