%X Objetivo. Validar una escala, de 27 ¨ªtems, para diagnosticar la calidad del servicio percibido por los usuarios de la biblioteca de una universidad p¨²blica. M¨¦todo. Se realiz¨® un estudio en una muestra de 437 usuarios, en el cual se evaluaron las propiedades de una escala adaptada del modelo LibQUAL+. La validez l¨®gica y de contenido fue evaluada por un grupo de expertos (Modelo de Lawshe), mientras que para indagar la estructura subyacente de los ¨ªtems se emple¨® el an¨¢lisis de componentes principales con rotaci¨®n Varimax. Resultados. Se identific¨® la existencia de cuatro variables que explican el 63.038% de la variaci¨®n; se descartaron 2 ¨ªtems por presentar cargas muy bajas en el an¨¢lisis factorial. Las pruebas de validez y consistencia interna de la escala son satisfactorias. El instrumento qued¨® integrado por 25 ¨ªtems cuyo Alfa de Cronbach fue 0.929. Conclusiones. Se obtuvo un instrumento v¨¢lido y ¨²til para evaluar la calidad del servicio de la biblioteca en el contexto estudiado. Objective. The aim of this study is to develop and validate a specific instrument to assess the service quality of the public university library. Method. The scale was applied to 437users. A self-administered instrument (27 items) was designed to measure the service quality perceived by library users. It was submitted for review by a multidisciplinary group of experts who assessed its logical and content validity (Lawshe¡äs Model). To determine the construct validity, a factor analysis was used with main components and Varimax rotation. Results. Two items were eliminated from the analysis because they showed a low correlation with the total correlation of the scale. The initial main-components analysis revealed four variables with an explained variation of de 63.038%. The scale has good inner validity and consistency. Consequently, final scale was accepted with 25 items. The global rating of the questionnaire had a Cronbach¡¯s alpha of 0.929. Conclusions. It is possible to affirm that the referred instrument is a valid and useful approach to evaluate the service quality of library under this specified context. Objetivo.
