Validación lingüística y psicométrica (adaptación cultural) de la escala Plutss para disfunción del tracto urinario inferior en niños colombianos
Thesis
80% of children with recurrent urinary infection have any symptoms of lower urinary tract dysfunction. To characterize these symptoms, objectively forced the use of scales to rate each of them. Today there are three validated tools to assess the lower urinary tract disorders in children, but none has been been translated into Spanish and culturally adapted to the Hispanic American population. The aim of this study is to adapt the scale PLUTSS cultural, which is proven and widely used, to apply in a group of Colombian children, thus establishing the behavior of these symptoms. METHODOLOGY: The scale PLUTSS (Pediatric Symptom Score Lower Urinary Tract) was translated into Spanish adapted to Colombian dialect according to the admissions standards of translation, synthesis, back translation and recommendation of experts, was applied to a group of 34 patients with clinical diagnosis of urinary tract disorder lower and 95 healthy controls. Validation was conducted appearance, construct validation, we assessed the internal consistency of the instrument, and compared with results obtained in the original scale. RESULTS: The median of the two groups (healthy and diseased) was significantly different, with a sensitivity and specificity of 90% cut off point 1.5. Internal consistency of the 13-item scale was high alpha Crobanch, (0.88). Established the criterion validity of the scale with the clinical diagnosis found a significant correlation of strong character (CONCLUSIONS: The scale linguistic and psychometrically validated PLUTSS under international standards validation of scales is the only scale adapted Spanish. showed a high correlation with the clinical diagnosis and high power to discriminate urinary symptoms.
