Summary

The aim of this study is to evaluate validity and reliability of a novel digital pain measure tool, the Faces Thermometer Scale (FTS). Pain is commonly reported by children and adolescents undergoing dental treatment. Pain is also a strongly contributing factor in the development of Dental Fear and Anxiety (DFA). Professionals often underestimate the pain perceived by their patients. Self-report tools are seldom used to measure pain in a clinical setting, denying child patients the possibility to communicate their pain experiences.

The aim of this study is to evaluate validity and reliability of a digital self-report pain measure tool, the Faces Thermometer Scale (FTS). Children and adolescents (N=150) aged 8 to 17 years visiting a dental clinic will be asked to score their pain using three different self-report pain tools; FTS, Faces Pain Scale-Revised (FPS-R) and Color Analog Scale (CAS). The validity and reliability of FPS-R and CAS is long established and will therefore be used to evaluate the psychometric properties of FTS.

Faces Thermometer Scale (FTS)

The Faces Thermometer Scale (FTS) is a one-item measure with 11 numeric rating scale steps (0, no pain to 10, much pain). Each step is associated with different faces and colors. The app presents all information in text, sound, and picture. FTS is part of PicPecc, an application for mobile devices. The child/adolescent assesses their pain on a tablet by moving the finger on the scale and points to the color and face that represent their appraised level of pain.
