BACKGROUND: Craniofacial Pain and Disability Inventory (CF-PDI/Brazil [Br]) assesses Temporomandibular Disorders (TMD)-related disability, and the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK/TMD-Br) assesses kinesiophobia in patients with TMD.
OBJECTIVE: To evaluate the responsiveness and interpretability of CF-PDI/Br and TSK/TMD-Br scores in chronic TMD patients.
METHODS: A total of 148 participants of both sexes (38, SD = 10.9 years) were included. Participants were reassessed after undergoing a 6-week rehabilitation treatment. Spearman correlations between change scores of the CF-PDI/Br and TSK/TMD-Br were compared with pain intensity and pain self-efficacy (responsiveness-construct approach). Accuracy (Area Under the Curve = AUC) was assessed by considering patients who improved or not, using the perceived global effect of improvement scale as an external anchor (responsiveness-construct approach). Interpretability assessed by minimal important change (MIC) estimate was also calculated using three methods: MICROC, MICmean and MICpredict.
RESULTS: CF-PDI and TSK/TMD exhibited suitable responsiveness. More than 75% of the hypothesized correlations between change scores for CF-PDI and TSK/TMD were confirmed, and both measures showed AUC > 0.70 to distinguish patients who improved from patients who did not improve. We found MICpredict of -5.3 and -4, respectively, for the CF-PDI and TSK/TMD scores.
CONCLUSIONS: CF-PDI/Br and TSK/TMD-Br demonstrated appropriate responsiveness and interpretability for patients with chronic TMD. The MIC values presented can be used to evaluate whether improvements in TMD-related disability and kinesiophobia are clinically meaningful. A change score decrease of at least -5.3 and -4 points in the total CF-PDI/Br and TSK/TMD-Br scores, respectively, indicates clinically significant improvement.
