Design and validation of the revised Regional Identity Scale (RIS-2) / Diseño y validación de la Escala de Identidad Regional revisada (RIS-2)

Abstract With the objective of theoretically and psychometrically updating the Regional Identity Scale (RIS) proposed by Zúñiga and Asún in 2004 and expanding the population for which it shows evidence of validity, a revision and revalidation of this instrument was performed via two studies. The first study included 1,113 university students from four regions of Chile, and the second included 1,200 adults from the same regions. Both samples were obtained via a random design through multistage conglomerates. The results enable us to propose a new version of the original scale (RIS-2) with suitable reliability indexes, solid evidence of both convergent validity and internal structure validity, and items with satisfactory psychometric quality. Furthermore, we verify the presence of a multifactor structure with three highly correlated dimensions. We conclude that the RIS-2 is a reliable, valid and conceptually broader instrument than the preceding version, so it is a useful tool to measure the intensity of regional identity in both university students and the adult population.
