This is important since blood samples are much easier to obtain and can be used for large-scale epidemiological studies [ 28].
Developers require an API that is easy to use for application of any scale, local or global.
The verbal rating scale is a commonly used scale, easier to understand than Visual Analog Scale.
We also found a slight advantage for frequency terms in regard to intraindividual stability, adding further evidence to the assumption that frequency scales might be easier to use for patients than intensity scales.
Customized five-point likert scale responses were used for the four statements, as follows: (1) More difficult = 1, difficult = 2, neutral = 3, easy = 4, easier = 5.
Magnetron sputtering from compound targets is widely used for the deposition of compound films since it is easy to scale up and it exhibits a high reproducibility.
Validated scales were used for all measurements.
The HADS is an easy-to-administer and brief screening measure used for assessing symptoms of anxiety and depression on two subscales (seven items each scale).
Models used for developmental and genetic studies must also offer rapid development, short generation time, be amenable to large scale cultivation, have small seed size for easy storage of many genotypes, and provide ample tissue for experimentation [ 1].
This was a subjective evaluation performed by the operator, for which a five-point Likert scale was used ((1) very easy insertion, (2) easy insertion, (3) neither easy nor difficult insertion, (4) difficult insertion, and (5) very difficult insertion).
