Estudio de la estructura factorial de la escala de calidad de vida FACIT-P para los pacientes con cáncer de próstata

Article information

Resumen

Objetivo

Realizar el análisis de la estructura de dominios de la escala FACIT-P (4.a versión), instrumento diseñado para medir el constructo de calidad de vida en pacientes con cáncer de próstata (CP).

Métodos

El método seleccionado para delimitar las variables latentes fue el de máxima verosimilitud. La estructura factorial escogida para buscar variables latentes partió de una rotación ortogonal tipo varimax.

Resultados

En los pacientes evaluados, más de la mitad procedían de Bogotá, la gran mayoría solo había cursado primaria, y de acuerdo con la escala Gleason, una cuarta parte presentaba un CP de grado intermedio o alto. Los dominios incluidos fueron: 1. aspectos que representan dolor y molestias; 2. elementos relacionados con autonomía y capacidad de desempeño; 3. aspectos de red social, familiar y satisfacción; 4. elementos relacionados con depresión y ansiedad; 5. síntomas específicos del cáncer de próstata.

Conclusiones

La estructura de dominios que muestra el instrumento en pacientes colombianos con CP mostró una organización de variables latentes plausible, y similares al constructo de la escala original.

Abstract

Objective

To analyze the dominion structure of the FACIT-P scale (4th version), an instrument designed to measure the quality of life construct in prostate cancer (PC) patients.

Methods

The selected method sought to achieve greatest possible verisimilitude for discrimination of latent variables. The factorial structure chosen to single out latent variables was based upon varimax orthogonal rotation.

Results

More than half the number of patients evaluated came from Bogota; a large majority had only primary school education; on the Gleason scale, one fourth suffered from intermediate or high grade PC. Dominions included aspects related to: 1. Pain and discomfort; 2. Independence and performance capacity; 3. Social network, family life and contentment; 4. Depression and anxiety; 5. Specific symptoms related to prostate cancer.

Conclusions

The dominion structure produced by the instrument among Colombian PC patients revealed a plausible latent variable organization that resembled the original scale construct.
