Visual Analog Scale

At enrollment, a demographic form, asthma control questions and spirometry were administered.

Diary symptoms were grand mean centered, where 0 represented the average level of the measure, and entered simultaneously into the model. Validity and clinical usefulness of VAS has often been evaluated in comparison to an objective assessment of airway obstruction such as FEV1. Assessment of asthma severity and asthma control in children.

All four of these presentation methods can be administered on paper or webform, but only the Verbal and Numerical methods can be presented orally — in a telephone or personal interview. We can adjust your values by just re-measuring your answer. Studies of acute pain in the emergency medicine setting have suggested that change in consecutive VAS scores should be at least 9 Kelly or 13 Todd et al.

The Visual Analog Scale for Pain

Visual Analog Scale Values by Method of Administration The median afternoon score for the patients completing a new VAS form was 30. Model 1 examined the relationship between VAS-pm and the evening diary variables of limited activity, shortness of breath, wheeze, and SABA use as time varying covariates.

We found approximately the same magnitude of change to be important, but not across the board.

Visual Analog Scale (VAS)

A large-scale study using a sample representing a broad spectrum of symptom severity is warranted to assure the replicability of our findings prior to broad clinical implementation of VAS as a symptom monitoring tool. Emergency department visits by urban African American children with asthma.

Visual Analog Scale

The purpose of this study was to determine the concurrent validity of VAS in capturing diurnal changes in symptoms and to examine the relationships between VAS and asthma control and pulmonary function. We do not recommend replacing the VAS with a three-category scale, because that might sacrifice the documented reliability and validity of the VAS and will not allow an assessment of the amount of change.
