How are rating scales related to validity?

A rating scale is valid if it measures what it is intended to measure in the specific study. The validity of self-estimated subjective phenomena is relative and cannot be assessed absolutely. The main concepts are criterion, construct, and content validity, but a large number of sub concepts are used.

What is the numerical rating scale?

Numerical rating scales A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. For example, 0–10 where 0 is no pain and 10 is the worst pain imaginable (Fig. 13.3). Commonly used NRS are 11 point (0–10), 21 point (0–20) and 101 point (0–100) (Jensen & Karoly 2001).

Is the reliability of the verbal rating scale strong?

Reliability was strong in all age subgroups, including each year of age from 4 to 7 years. Convergent validity, known-groups validity, responsivity, and reliability of the Verbal Numerical Rating Scale were strong for children aged 6 to 17 years. Convergent validity was not strong for children aged 4 and 5 years.

What are reliability and validity of measurement scales?

Reliability and validity, jointly called the “psychometric properties” of measurement scales, are the yardsticks against which the adequacy and accuracy of our measurement procedures are evaluated in scientific research.

What is the reliability coefficient of a test?

The reliability coefficient obtained by repetition of the same measure on a second occasion is called the test-retest reliability.

Which is the most reliable pain rating scale?

Validity and Reliability of the Verbal Numerical Rating Scale for Children Aged 4 to 17 Years With Acute Pain The Verbal Numerical Rating Scale is the most commonly used self-report measure of pain intensity. It is unclear how the validity and reliability of the scale scores vary across children’s ages.
