Adaptación al castellano de la escala de confianza general de ya-magishi

Abstract

The significance that trust has in social exchange relationships has led to a growing amount of literature dealing with this phenomenon at a theoretical and an applied level. With the aim of conducting trust research by means of an instrument with established reliability and validity, the General Trust Scale (Yamagishi & Yamagishi, 1994) was translated into Spanish. The sample comprised 626 participants. Results indicate that the Spanish adaptation has satisfactory psychometric properties: test's reliability (α = .862) and items' discrimination (a ≥ 1.58). There was no differential item functioning regarding the participants' gender, but differences aroused as regards to their age. The relationship with several dispositional and be-havioral variables was assessed, being significant its correlation with Agree-ableness (r = .376) and, for the women, also with Openness to Experience (r = .135). © 2014: Servicio de Publicaciones de la Universidad de Murcia.
