When designing the Ghanaian figural stimuli, the models were created on a computerized interval scale rather than an ordinal scale and we also included models that represented the far extremes of weight from cachexia to morbidly obesity.
To overcome the limitations of current dietary assessment methodology, scientists at the USDA, ARS, Western Human Nutrition Research Center WHNRCC) developed a computerized food-scale system named NESSy, Nutrition Evaluation Scale System (US Patent 5,233,5200).
Pain rating was performed using a computerized visual analogue scale (0 100) digitized at 1/s, either immediately online or one hour or one day after injection.
In the two ischaemic block groups, current level of pain was also monitored using a computerized visual analogue scale (VAS) at the beginning and end of the procedure.
Subjects used a computerized visual analogue scale (COVAS, Medoc, Ramat-Yishai, Israel) for continuous reporting of itch intensity for a duration of 5.5 minutes.
In the latter test, subjects rated the viscosity of 0.25, 0.50, 0.75, 1, and 2% XG samples using a computerized labeled magnitude scale (LMS) system.
After scanning, participants were asked to rate the intensity of others' pain and of their own feelings of unpleasantness on the basis of the same visual stimuli by using a computerized visual analogue scale (VAS) with target words ranging from "no pain" to "extreme pain" and from "no effect" to "extreme unpleasantness".
For each of these labels, ratings were made using a single, computerized visual analog scale (VAS, see Figure S1), anchored at "other skin" and "own skin," with the mid-point representing no felt difference between the two.
The participant was asked to rate her current mood state using a computerized visual analogue scale that ranged from -10 (indicating saddest mood) to 10 (indicating happiest mood) at baseline and after the mood induction.
