About this trial
Pain in the orofacial region has a 10% prevalence in the general population and health care providers are therefore expected to encounter these patients on a daily basis. Chronic orofacial pain often presents as jaw pain related to overload of the jaw muscles and temporomandibular joints. The aim of this study is to evaluate the effectiveness of a smartphone-based behavioural intervention (Ecological Momentary Intervention, EMI) grounded in Cognitive Behavioural Therapy (CBT), compared to standard treatment with an occlusal splint and a waiting list control group.

Trial outcomes
Primary outcomes
Change in pain intensity
Pain level will be assessed using the Numeric rating Scale (NRS, a scale ranging from 0 (no pain) to 10 (worst pain imaginable). A 30% reduction in pain according to the NRS is considered a significant effect.
Secondary outcomes
Cost-effectiveness
Cost-effectiveness will be assessed using direct and indirect costs to calculate total societal costs for the two different interventions
Stress-levels
Assessment of stress will be done using the Perceived stress-scale (PSS-10) which yields a total score from 0 to 40, calculated by summing responses to 10 items, each scored on a 5-point Likert scale (0 = never to 4 = very often).
Changes in general well-being
Assessment of general wellbeing will be done with Patient Health Questionnaire (PHQ-4) which combines two 2-item scales: the PHQ-2 (depression) and the GAD-2 (anxiety). Each question is scored on a 4-point Likert scale (0-3), and the total score is the sum of all four items Higher scores indicate a greater severity of symptoms.
Correlation between pain and overload
During the first 3 days of using the mobistudy application, the relation between muscluskeletal overload and TMD-pain will be assessed.. Assessment of overload with Ecological momentary assessment of self-reported overload will be correlated (Spearman's correlated) to pain intensity using the Numeric rating Scale (NRS), a scale ranging from 0 (no pain) to 10 (worst pain imaginable).
Other outcomes
Coping
Coping will be assessed with the Brief Resilience Coping Scale (BRCS-4) using a 5-point Likert scale for each item, ranging from "Does not describe me at all" to "Describes me very well". The total score is calculated by summing the responses to all four items. Higher scores indicate a greater tendency toward resilient coping.
Headache
Assessment with the Headache screening questionnaire (HSQ). The HSQ aims to identify individuals who might have migraine or tension type headache by assessing headache characteristics across four domains: frequency, duration, characteristics, and symptoms.
Widespread pain
Widespread pain will be assessed by a pain manikin.
