Design outcomes

Primary

MeasureTime frame
A reduction in the level of anxiety reported by the assessed children is expected, as measured by the VPT Modified, which has a score ranging from 0 (no anxiety) to 8 (highest possible anxiety). We will observe whether there is a reduction of at least 1 point in the average score, considering this reduction as clinically relevant.

Secondary

MeasureTime frame
It is expected to observe more cooperative behavior among the children in the Intervention Group compared to the Control Group. This analysis will be conducted using the Brazilian version of the VENHAM Scale (BvVBRS) during the consultation. This scale has six categories, ranging from 0 (extremely cooperative) to 6 (generalized protest), and the percentages of each behavior level will be compared. The study will assess whether there is a higher percentage of cooperative behavior (0-1) in the Intervention Group compared to the Control Group.;It is expected that children in the Intervention Group will experience lower pain levels throughout the consultations compared to the Control Group. This will be assessed after the consultations using the Faces Pain Scale – Revised (FPS-R). This scale has six points (0, 2, 4, 6, 8, and 10), where 0 represents no pain and 10 represents the highest possible pain. It is a self-reported measure, and the percentage distribution between the groups will be analyzed. A lower level of pain is expected, with a lower percentage of children scoring in the higher pain categories (6, 8, 10) in the Intervention Group compared to the Control Group.
