Los técnicos en orientación profesional necesitan herramientas especializadas para medir la motivación de búsqueda de empleo. Entre los elementos que motivan a una persona a buscar trabajo destacan sus expectativas. Con el objetivo de evaluarlas, se creó la escala de Expectativas de Control Percibido de Búsqueda de Empleo (ECPBE) partiendo del modelo de Expectativas Generalizadas de Control (EGC) de Palenzuela. Se estudia la validez convergente-discriminante, la fiabilidad (consistencia interna y homogeneidad) y la validez factorial. Se obtienen correlaciones con las subescalas próximas teóricamente significativas y se confirma la presencia de cuatro factores para los ítems de autoeficacia, expectativas de éxito, locus de control interno y locus de control externo. Se puede considerar la ECPBE como una escala válida para medir las expectativas propuestas desde el modelo de EGC adaptado a la situación de búsqueda de empleo, presentando un adecuado nivel de homogeneidad y consistencia en la medida.

The construct of locus of control at present poses certain problems. It is defined in different ways by various investigators, and at times its definition is analogous to other concepts. The expectancy of locus of control is confused with the attributions of past success-failure experiences and recent approaches have proposed conflicting solutions. There is also terminological-conceptual confusion. Locus of control scales are used for the measurement of other constructs. The dimensionality of locus of control is still lacking in coherence, is confusing, and some scales also seem to measure several different concepts. The present article discusses such problems in two sections: (a) conceptual problems and (b) problems with the measurement of the locus of control. A third section describes some possible solutions; empirical evidence is presented on the first steps of an alternative approach.

This article discusses the interpretation put forward by Graybill and Sergeant of considering Collins' 1974 Difficult-Easy World Factor as a measure of perceived competence. Theoretical arguments are presented of how Collins' items do not seem to be linked to the perceived competence dimension postulated by Graybill and Sergeant but rather to the perceived contingency dimension. Several scales of locus of control and perceived self-efficacy were completed by 184 subjects. Stepwise multiple regression analyses offer clear empirical support to these theoretical arguments. The article concludes by suggesting a need to unravel the current confusion to introduce some coherence and to develop a general model of perceived control which will articulare the different constructs which constitute the nexus of confusion.
