This study falls within the theoretical framework of the construct of the Efficient Personality. In this work, we present the study of validity and reliability of an original questionnaire made up of 60 items, applied to students from formative cycles of higher Profesional Training. The questionnaire was reduced to 24 items, surpassing its initial 84 Cronbach alpha coefficient. Six first-order factors were obtained: Social Self-concept, Academic Self-concept, Solving Ability, Self-esteem, and Problem Coping. One second-order factor was obtained: Efficient Personality. The six-component factorial solution is similar both to the Spanish version for secondary school and to the Chilean versions for secondary and university populations, dividing the initial dimension of Self-concept into Self-concept and Self-esteem.
