Propiedades psicométricas de un instrumento de evaluación de barreras para la adherencia al tratamiento antirretroviral en población argentina
Barra lateral del artículo
Contenido principal del artículo
Objetivo: adaptar y validar un instrumento para evaluar barreras a la adherencia antirretroviral en personas que conviven con el vih en Córdoba (Argentina). Materiales y métodos: la muestra final incluyó 180 participantes argentinos. La media de edad fue de 40.61 (de = 12.032) y el 82.8 % fueron hombres. Sobre la muestra (n = 180) se efectuaron estudios de estructura interna, confiabilidad y validez con otras variables. Resultados: el análisis factorial confirmatorio arrojó resultados congruentes con la estructura factorial del estudio original, aunque para ello fue necesario eliminar ciertos ítems que presentaban bajas cargas factoriales
y que pueden ser representados por otros ítems, debido a información redundante. Se obtuvieron coeficientes ω = 0.833 en la subescala información; ω = 0.759 en la subescala motivación, y ω = 0.888 en la subescala habilidades comportamentales. Se encontraron correlaciones significativas entre los resultados de adherencia al tratamiento y barreras al tratamiento. Conclusión: aunque se requieren de mayores investigaciones, los resultados son promisorios, sugieren que el instrumento puede usarse para evaluar barreras de la adherencia al tratamiento antirretroviral en Córdoba.
