The determination of patient-based experiences with smartphone-based report of awake bruxism using a diary

Objectives: In recent years, a smartphone-based ecological momentary assessment (EMA) approach for assessing awake bruxism (AB) has attracted growing interest, both in clinical and research settings. The present study was designed to investigate subjects' experience using an EMA-based smartphone application to detect factors that could hamper or facilitate its use for clinical and research purposes.

Materials and methods: Thirty-two patients with temporomandibular disorders (TMDs) pain (14 males, 18 females; mean age 28.3 ± 12.1 years) were recruited at the Orofacial Pain Unit of the University of Siena, Siena, Italy. They were monitored for one week to collect data on their AB behaviors. Time investment, feelings, encountered difficulties, and reasons for not using the app were assessed in a diary with 5-point Likert scales. Descriptive analysis of quantitative data was assessed, and content analysis of textual data was performed.

Results: Quantitative data showed a good experience with the app (median of 4). The main motivation to use the EMA-based smartphone application was to gain insight into their own AB behaviours. The most negative experience was the short time window available to answer to the alert.

Conclusion: The EMA-based smartphone application was well accepted for multiple day evaluation.

Clinical relevance: These results open up important clinical scenarios for AB evaluation as well as the possibility to carry out large-scale studies on general population samples and/or on selected subpopulations.
