Inventario Psicológico de Ejecución Deportiva para Árbitros (IPEDA): Adaptación y Propiedades de Medida

Abstract

The study presents the adaptation and properties of the Psychological Inventory of Sports Performance (IPED to sports referee (IPEDA), which evaluates the psychological skills of the referee. The questionnaire is composed of 42 items divided into seven scales: self-confidence, negative coping control, attention control, visual and imaginative control, motivational level, positive coping control and attitudinal control. The sample consisted of 174 football referees, with a mean age of 22.41 years (SD=4.37). The scales have adequate internal consistency, the adjustment indexes (NFI, CFI, GFI and AGFI) are higher than .90, and the error rates (RMSEA, RMR and SRMR) around .08. In addition, through generalizability analysis the result is that sample is normal, linear and homoscedastic, with high levels of reliability (e2=1) and generalizability (F=1). These results indicate that the IPEDA is a valid and accurate instrument capable of providing reliable and generalizable results.
