Adaptación Cultural de la Weight Bias Internalization Scale (Wbis)
Contenido principal del artículo
Resumen
Este estudio tuvo como objetivo realizar la adaptación cultural y presentar evidencia inicial sobre las características psicométricas de la Escala de Interiorización de Prejuicios sobre Obesidad (Weight Bias Internalization Scale – WBIS) para el contexto brasileño, a través de tres etapas: traducción, validación semántica y pretest. La síntesis de las traducciones se consideró insatisfactoria y se obtuvo una nueva versión consensuada con un Comité de Expertos. Esta versión fue retrotraducida y utilizada en la validación semántica con 18 personas, lo que confirma la comprensión adecuada después de modificaciones en dos ítems. En el pretest, con 54 personas, el alfa de Cronbach se consideró adecuado (0,833), con efectos de floor y ceiling observados en nueve y cuatro ítems, respectivamente. El coeficiente de correlación de Pearson mostró la presencia de correlaciones fuertes y moderadas. La medición de la interiorización de los prejuicios sobre la obesidad representa una herramienta importante para apoyar estrategias terapéuticas más efectivas, con atención integral y humanizada.
