Shoulder pain and disability index: cross cultural validation and evaluation of psychometric properties of the Spanish version. Health Qual Life Outcomes. 2015; 13(1):200http://hdl.handle.net/10668/2379Journal Article; Research Support, Non-U.S. Gov't;BACKGROUND The Shoulder Pain Disability Index (SPADI) is a recently published but widely used outcome measure. METHODS This study included 136 patients with shoulder disorders. SPADI was first translated and back-translated and then subjected to psychometric validation. Participants completed the Spanish versions of the SPADI, general health (SF-12), the Simple Shoulder Test (SST), Disability of Arm, Shoulder, and Hand (DASH) questionnaires and a pain intensity visual analog scale (VAS). RESULTS The factors explained 62.8 % of the variance, with an internal consistency of α = 0.916 and 0.860, respectively. The confirmatory factor analysis showed a Comparative Fit Index of 0.82 and a Normed Fit Index of 0.80. The Root Mean Square Error of Aproximation was 0.12. The x (2) test for the 2-factor model was significant (x (2) = 185.41, df = 62, p < 0.01). The test-retest reliability was high, with an item ranging of the interclass correlation coefficient (ICC) from 0.89 to 0.93. The ICC for the total score was 0.91 (95 % CI 0.88 to 0.94). Measurement error by minimal detectable change (MDC)95 was 12.2 %. In the construct validity analysis, strong positive correlations were observed between Spanish Version of the SPADI and DASH (pain: r = 0.80; p < 0.01; disability: r = 0.76; p < 0.01). Moderate positive correlations were observed between Spanish Version of the SPADI and VAS (pain: r = 0.67; p < 0.01; disability: r = 0.65; p < 0.01). Moderate negative correlations were obtained between Spanish Version of the SPADI and SST-Sp (pain: r = -0.71; p < 0.01; disability: r = -0.75; p < 0.01). However, pain total Spanish Version of the SPADI was only weakly correlated with physical and mental components of SF-12 (both r = 0.40; p < 0.01). CONCLUSIONS This Spanish version of SPADI demonstrated satisfactory psychometric properties in a patient sample in the hospital setting.enShoulderSpanishPatient reported outcomesAnálisis factorialEvaluación de Resultado (atención de salud)Dimensión del dolorPsicometríaReproducibilidad de resultadosHombroDolor de hombroEncuestas y cuestionariosTraducciónEscala visual analógicaMedical Subject Headings::Anatomy::Body Regions::Extremities::Upper Extremity::ArmMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Statistics as Topic::Factor Analysis, StatisticalMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Health Care::Health Care Quality, Access, and Evaluation::Quality of Health Care::Health Care Evaluation Mechanisms::Outcome and Process Assessment (Health Care)Medical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Neurological::Neurologic Examination::Pain MeasurementMedical Subject Headings::Psychiatry and Psychology::Behavioral Disciplines and Activities::Psychological Tests::PsychometricsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Evaluation Studies as Topic::Reproducibility of ResultsMedical Subject Headings::Anatomy::Body Regions::Extremities::Upper Extremity::ShoulderMedical Subject Headings::Diseases::Musculoskeletal Diseases::Joint Diseases::Arthralgia::Shoulder PainMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::QuestionnairesMedical Subject Headings::Information Science::Information Science::Communication::Language::Language Arts::TranslatingMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Visual Analog Scaleresearch article26690943open access10.1186/s12955-015-0397-z1477-7525PMC4687317
