El objetivo del artículo consiste en el análisis psicométrico de los instrumentos de utilización más frecuente para la medida del amor,y que cuentan con un mayor apoyo conceptual y empírico.Se han considerado las escalas de Knox-Sporakowski, Rubin, Hendrick-Hendrick, Critelli, Sternberg y Hatfield.Se han administrado a una amplia muestra de sujetos,obteniéndose de cada escala sus características estructurales y psicométricas.Se presentan los resultados y se hace una evaluación de cada instrumento de medida considerado.Las escalas de Rubin, Critelli, Sternberg y Hatfield presentan una adecuada consistencia interna.Se valora la sencillez de la escala de Rubin y la capacidad de las de Critelli y Sternberg para dar una medida general del amor
The aim of this paper is the psychometrical analysis of those instruments which are generally used in the measurement of love and are considered to have the greatest conceptual and empirical support. We have taken into account the scales developed by Knox-Sporakowsky, Rubin, Hendrick-Hendrick, Critelli, Sternberg and Hatfield, which have been applied to a wide sample of subjects, in order to obtain their structural and psychometric profiles from each scale. We present the results and evaluate each of the instruments considered. The scales of Rubin, Critelli, Sternberg and Hatfield offer an appropiate internal consistency. We appreciate the simplicity of Rubin's scale and those developed by Critelli and Sternberg, as they are capable of providing a general measurement of love.
