Construcción y validación de una escala de asertividad en la relación paciente-médico

The objective of this study was the construction and validation of an instrument to evaluate patients' assertiveness with the medical personnel. Two hundred and sixteen patients with chronic degenerative diseases (Mage = 42.74, SD = 8.76), from a public hospital in Mexico City participated in this study, selected through a non probability haphazard sampling. In order to validate this instrument, an analysis was carried out evaluating the discriminative power of the items, the reliability and the factorial structure were obtained. The final scale contains 21 items, that explain 44.29% of the total variance and the theoretical coherence of the structure distributed on 4 factors: Non Assertiveness-Passivity, Non Assertiveness-Insecurity, Positive-Assertiveness and Aggressiveness, this instrument has a reliability level of α = .816, so it is concluded that this scale complies with the reliability and validity criteria to measure the assertiveness on clinic practice and investigation, with the limitation regarding its validation in the hospitalary population of Mexico City.
