The visual analogue scale or visual analog scale is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured.

What does the visual analog scale measure?

Visual analogue scales (VAS) are psychometric response scales used to measure subjective characteristics or attitudes and have been used in the past for a multitude of disorders, as well as in market research and social science investigations, among others [3, 4].

Why is the visual analog scale used?

A Visual Analogue Scale (VAS) is a measurement instrument that tries to measure a characteristic or attitude that is believed to range across a continuum of values and cannot easily be directly measured. It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms.

How does the visual analog scale work?

Background: The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between “no pain” and “worst pain.”

What is 100 mm visual analog scale?

The pain VAS is a continuous scale comprised of a horizontal (HVAS) or vertical (VVAS) line, usually 10 centimeters (100 mm) in length, anchored by 2 verbal descriptors, one for each symptom extreme (2, 6).

What is a good VAS score?

The findings suggested that 100-mm VAS ratings of 0 to 4 mm can be considered no pain; 5 to 44 mm, mild pain; 45 to 74 mm, moderate pain; and 75 to 100 mm, severe pain.

What are analog scales?

Analog scales, also known as mechanical scales, offer a simple and reliable way to measure weight accurately. Easy to use, these scales require no batteries to replace, and require little maintenance beyond occasionally adjusting the scale back to zero.

Is visual analog scale ordinal?

To evaluate the degree of pain, a Likert-type scale, such as numerical rating scale (NRS) or visual analog scale (VAS), is frequently used. Those scales are generally categorized as ordinal scales which means that parametric statistics are not appropriate for those scales.

What is VAS in allergic rhinitis?

Visual analogue scale (VAS) is an instrument that can be used in daily practice. VAS is usually a horizontal 100 mm long scale with two opposing descriptors at its end points. Patients with allergic rhinitis specify a point on the scale that best corresponds to the severity of their symptoms.

What is visual analogue scale for pain?

The visual analog scale (VAS) is a tool widely used to measure pain. A patient is asked to indicate his/her perceived pain intensity (most commonly) along a 100 mm horizontal line, and this rating is then measured from the left edge (=VAS score).

What tools can you use in assessing pain?

Pain Assessment Scales

• Numerical Rating Scale (NRS)
• Visual Analog Scale (VAS)
• Defense and Veterans Pain Rating Scale (DVPRS)
• Adult Non-Verbal Pain Scale (NVPS)
• Pain Assessment in Advanced Dementia Scale (PAINAD)
• Behavioral Pain Scale (BPS)
• Critical-Care Observation Tool (CPOT)

Who invented the visual analogue scale?

The VAS (i.e., continuous scale) was first introduced in 1921 by two employees of the Scott Paper Company (Hayes & Patterson, 1921). They developed the scale as a method for supervisors to rate their workers.

Are visual analogue scales reliable?

Conclusions: Reliability of the VAS for acute pain measurement as assessed by the ICC appears to be high. Ninety percent of the pain ratings were reproducible within 9 mm. These data suggest that the VAS is sufficiently reliable to be used to assess acute pain.

How do you do VAS pain?

The Visual Analogue Scale (VAS) consists of a straight line with the endpoints defining extreme limits such as 'no pain at all' and 'pain as bad as it could be' (Fig. 1) [1]. The patient is asked to mark his pain level on the line between the two endpoints.

Can fatigue be measured on a visual analogue scale?

Visual Analog Fatigue Scale (VAFS) —

The score was obtained by measuring the line from “No Fatigue” to the point indicated by the subject that represents their fatigue level, the higher the VAFS score, the higher the fatigue.

Is a Likert scale a visual analog scale?

In measuring the degree of agreement with a statement, the response options are often presented in a Likert-type scale with a certain number of ordinal answer options. An alternative to Likert-type scales are visual analogue scales (VASs).

Is visual analog scale continuous?

This continuous (or "analogue") aspect of the scale differentiates it from discrete scales such as the Likert scale. There is evidence showing that visual analogue scales have superior metrical characteristics than discrete scales, thus a wider range of statistical methods can be applied to the measurements.

What is the numerical pain rating scale?

The Numerical Pain Rating Scale (NPRS) is a subjective measure in which individuals rate their pain on an eleven-point numerical scale. The scale is composed of 0 (no pain at all) to 10 (worst imaginable pain).

What is the verbal rating scale?

Verbal rating scales are powerful tools used to assess pain experiences. Verbal rating scales, also known as verbal pain scores and verbal descriptor scales, are self-reports which consist of a number of statements designed to describe pain intensity and duration (Karcioglu et al., 2018).

What type of data is pain?

Conventionally, pain scores are considered ordinal data, i.e. categorical data in order. In statistics, ordinal data is considered non-parametric, i.e. data with skewed distribution (Manikandan 2011).

What is the face pain scale called?

The Wong–Baker Faces Pain Rating Scale is a pain scale that was developed by Donna Wong and Connie Baker. The scale shows a series of faces ranging from a happy face at 0, or "no hurt", to a crying face at 10, which represents "hurts like the worst pain imaginable".

What type of variable is pain?

In this case, pain is a numerical variable. However, in figure 2, pain intensity is analyzed in different categories—none, mild, moderate, severe. In this case, pain is an ordinal variable. Because the variable types are different in each case, the statistical test used to calculate results will be different as well.

Which scale is the most accurate?

1. Most accurate scale. The sleek RENPHO Bluetooth Body Fat Scale syncs directly to your phone and tracks 13 different measurements of body composition, including body weight, BMI, and body fat percentage.

Which weighing scale is best analog or digital?

Accuracy. In terms of accuracy, digital weighing scales certainly score more points over analog weighing scales. The former is proven to give the most precise weight measurement. In addition to this, analog scales will display the weight to the nearest decimal point.

What is a digital scale?

A digital scale is a measuring device that reads and displays the weight of an object. Unlike an analog balance scale, a digital scale is a high-quality scale that gives a more correct weight reading.
