Aims: To explore whether temporomandibular disorder (TMD) pain patients reporting different levels of pain-related disability differ in terms of illness explanations and treatment expectations. Methods: Consecutive TMD pain patients (n = 399; mean ± SD age, 40.5 ± 12.7 years; 83% women) seeking treatment in primary care completed the Explanatory Model Scale (EMS). Patients were asked to indicate their expectations regarding the treatment. Each patient's pain-related disability level was determined using the Graded Chronic Pain Scale, with scores indicating no (0 disability points), low (1-2 disability points), or high (3-6 disability points) disability. Differences between EMS factor scores were evaluated using the Mann-Whitney U test. Differences between study groups were analyzed using logistic regression. Results: High-disability patients considered physical and stress factors as more important in causing and in aggravating pain and as targets of treatment compared with patients with no disability (P = .0196 and P = .0251, respectively). The great majority of patients indicated they would like to receive information, decrease pain, and increase jaw function, with no significant subtype differences noted. Compared with no-disability patients, low-disability and high-disability patients were more likely to expect increased ability to perform daily functions (P .0001 in both comparisons), increased work ability (P .0001 in both comparisons), and better stress management skills (P = .0014 and P = .0001, respectively). Conclusion: Illness explanations and goals for treatment differ in patients reporting different levels of TMD pain-related disability.
