Assessment of pruritus intensity: prospective study on validity and reliability of the visual analogue scale, numerical rating scale and verbal rating scale in 471 patients with chronic pruritus.

Visual analogue scale: evaluation of the instrument for the assessment of pruritus.

The aim of this study was to evaluate the visual analogue scale (VAS) as a method of pruritus assessment. A total of 310 subjects with pruritic dermatoses (148 Caucasian subjects and 162 Asian subjects) were recruited. The patients assessed pruritus intensity using the horizontal and vertical VAS, numeric rating scale (NRS) and verbal rating scale (VRS). All scales showed very good reproducibil...

Verbalizing extremes of the visual analogue scale for pruritus: a consensus statement.

Itch (pruritus) is an unpleasant sensation that leads to the desire to scratch (1). Pruritus may compromise quality of life and sleep in affected individuals. Pruritus is similar to pain, in being a subjective symptom; assessment of its intensity is a key issue in evaluating severity and therapeutic outcome of patients with pruritic disorders of diverse origins (cutaneous, systemic, neuropathic...

Dynamic Pruritus Score: Evaluation of the Validity and Reliability of a New Instrument to Assess the Course of Pruritus.

Currently valid itch intensity scales, such as the visual analogue scale (VAS), are indispensable, but they can be influenced by the patient's overall health status. The aim of this study was to evaluate the reliability and validity of the Dynamic Pruritus Score (DPS), a new instrument comparing reduction in current pruritus with a defined earlier time-point. Eighty-one randomly selected adults...

Background and Aim: Pruritus is a major symptom of dermatologic diseases and a common symptom of systemic diseases. Severity of itch cannot be measured objectively. It’s usually determined to using a Visual Analogue Scale (VAS). But none of them can determine the effect of pruritus on patients' quality of life. So in the present study we sought to translate and develop a validated reliable...
