Abstract: OBJECTIVES: Structured patient-centred assessment is critical for improving care. OHIP-TMDs are a validated English-language outcome measure for temporomandibular disorders (TMD) which evaluates the biopsychosocial impact of TMD. Due to language and cultural changes, the original instrument's phrasing of its items may change when translated to Spanish. This study cross-culturally adapted and validated OHIP-TMDs for Spanish-speaking individuals with TMD. METHODS: OHIP-TMDs was forward-backward translated into Spanish (OHIP-TMDs-Sp) and cross-culturally adapted to a Hispanic population with TMD (Diagnostic Criteria for TMD n = 154) according to international norms. All patients completed the OHIP-TMDs-Sp, the Graded Chronic Pain Scale (GCPS), and Jaw Functional Limitation Scale (JFLS-20). A subsample (n = 30) recompleted the OHIP-TMDs-Sp after a 3-week washout to measure test-retest reliability using an intra-class correlation coefficient (ICC 2.1). OHIP-TMDs-Sp, JFLS-20, and GCPS were analysed for convergent validity and internal consistency. RESULTS: The sample with articular and muscular TMD diagnoses was 85.7% female with a mean age of 29.5. (SD 9.01). OHIP-TMDs-Sp had high internal reliability (Cronbach's Alpha = 0.95) and good test-retest reliability (ICC = 0.82; 95% CI = 0.57-0.93). In terms of convergent validity, the OHIP-TMDs-Sp demonstrated moderate to large positive correlations with the total JLFS-20 score (ρ = 0.72; p < 0.01), Mastication (ρ = 0.68; p < 0.01), Communication (ρ = 0.68; p < 0.001), as well to GCPS disability score (ρ = 0.59; p < 0.01), and characteristic pain intensity (ρ = 0.69; p < 0.01). CONCLUSIONS: The total score of OHIP-TMDs-Sp is reliable for assessing quality-of-life in Spanish-speaking TMD patients.
