The goals of this study were to evaluate the validity of the visual analogue scale (VAS) for young @entity1 and to compare a newly developed method of teaching @entity1 to use a VAS with one used in our previous studies. It was hypothesized that the new method would increase the number of @entity1 who understand the VAS and correctly mark their responses on the VAS line. The association between @entity1 's age and ability to understand the VAS was also evaluated. One hundred-six @entity1 with a laceration requiring sutures and receiving a @entity3303 injection for local anesthesia participated in the study. They ranged in age from 5 to 14 years. Two outcome measures were used to assess the baseline and @entity3303 injection @entity158 : a 5-point Likert scale and a VAS. A calibration study was used to determine whether the subjects were able to use the VAS to make proportional judgments about their perceptions. Teaching method had no effect on the number of subjects who could correctly mark their responses on the VAS line, nor did it significantly increase the number of subjects who could understand the concept of the VAS. Subjects who were able to understand the VAS were significantly older (mean = 9.8 years, SD = 2.8) than those who did not (mean = 8.2 years, SD = 2.5). Overall, only about one third of the subjects were able to correctly mark the VAS and understand the concept of the VAS. Other measures of @entity158 that are better understood by young @entity1 may be more valid indicators of @entity158 than the VAS.
