Review of self-reported instruments that measure sleep dysfunction in patients suffering from temporomandibular disorders and/or orofacial pain


Sommer, Isabelle; Lavigne, Gilles; Ettlin, Dominik A (2015). Review of self-reported instruments that measure sleep dysfunction in patients suffering from temporomandibular disorders and/or orofacial pain. Sleep Medicine, 16(1):27-38.

Abstract

Patients with temporomandibular disorders (TMD) and/or orofacial pain (OFP) frequently experience poor sleep quality or suffer from comorbid sleep disorders. Study results suggest that in chronic pain patients, an improvement in sleep quality critically influences the outcomes of interventions on mood and pain. Yet, only a few studies have systematically sought to evaluate the sleep quality of TMD/OFP patients. Standardized and validated self-reported instruments designed for screening sleep disturbances or for the evaluation of treatment outcomes in this population would therefore enhance evidence and improve treatment options. The objectives of the present study were: (1) to review the self-reported instruments that measure sleep dysfunction in studies on TMD/OFP patients, by conducting a systematic literature search; (2) to evaluate their clinimetric evidence; and (3) to provide guidance for future research using such instruments. A total of 26 papers, using eight different instruments, were identified. The most frequently used questionnaires and the only ones with good clinimetric properties were the Insomnia Severity Index followed by the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale. They were most reliable, valid and time-effective for measuring sleep dysfunctions in patients with TMD/OFP, with only a few practical constraints. Yet, in future studies, an assessment of the relationship between sleep disturbances and chronic pain will have to include instruments measuring the effect of mediator variables such as cognitive or emotional arousal. Research is required to clarify if existing self-reported questionnaires measuring these aspects will promote further insights or if there is a need for new instruments. This future research direction would blend into the overall biopsychosocial concept of TMD/OFP diagnoses and treatment.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
