Introduction: In Colombia, there are few studies that have evaluated the health-related quality of life (HRQOL) of individuals infected with HIV/AIDS through MOSSF-36, WHOQOL-BREF or WHOQOL-HIV-BREF and no studies have been reported comparing some of its psychometric properties. Objective: To describe the HRQOL and to analyze the psychometric properties of two generic and one specific instruments to measure HRQOL in a group of people living with HIV/AIDS in Medellin, Colombia, 2009. Methodology: Cross-sectional study in a nonrandom sample of 187 subjects with HIV/AIDS. The MOSSF-36, WHOQOL-BREF, and WHOQOL-HIV-BREF were applied. The description was made with proportions and summary measures; reliability was assessed with Cronbach's alpha, Pearson's correlation coefficients were used for internal consistency and discriminant validity, and the convergent/divergent validity of the concepts of HRQOL with the correlation among the domains of the instruments. Results: Higher HRQOL scores were observed in Physical Function, Environment, Level of Independence and Spirituality. The MOSS-36 showed an excellent level of reliability, internal consistency and discriminant validity in its eight domains; the WHOQOL-BREF presented excellent psychometric properties in Physical Health, Environment and Social Relations, and good properties in Psychological Health; whereas, the WHOQOL-HIV-BREF had excellent psychometric properties in Social Relations, Environment, Spirituality and Independence and good properties in Physical and Psychological Health. There were correlations above 0.4 among domains of different instruments, which show the convergence of the measurement of HRQOL with the instruments applied. Conclusion: The MOSSF-36 showed a perfect profile of psychometric characteristics, the WHOQOL-BREF and WHOQOL-HIV-BREF were an acceptable level and the constructs of the three instruments converge, indicating good development of tools for studying HRQOL in HIV/AIDS infected individuals in Colombia.
Introducción: El instrumento de calidad de vida de la Organización Mundial de la Salud es ampliamente utilizado en personas sanas y enfermas; sin embargo, son pocos los estudios colombianos que han analizado sus dimensiones en población sana. Objetivo: Evaluar las propiedades psicométricas del WHOQOL-BREF en población sana de Medellín, y estimar los intervalos de referencia para sus cuatro dimensiones. Métodos: Estudio transversal y de evaluación psicométrica en 1938 personas. Se evaluó fiabilidad con el α de Cronbach, consistencia interna y poder discriminante con Rho de Spearman, validez de contenido con coeficientes λ y varianza explicada mediante un análisis factorial exploratorio con extracción por componentes principales. Se eliminaron valores aberrantes mediante el estadístico de Grubbs, se estimaron los intervalos de referencia globales para cada dimensión del WHOQOL-BREF y los específicos, según variables demográficas y socioeconómicas, mediante intervalos de confianza del 95% para la media, y comparaciones mediante T- Student y Anova. Los análisis se realizaron en SPPS 25.0®. Resultados: Se halló una excelente fiabilidad, consistencia interna, poder discriminante y validez de contenido en las cuatro dimensiones del instrumento en población sana. Los valores de referencia fueron 64,3-65,6 en salud física, 70,8-72,0 en salud psicológica, 64,3-65,9 en salud social y 60,5-61,6 en salud ambiental, con diferencias estadísticamente significativas según las características demográficas y socioeconómicas Conclusión: El excelente desempeño psicométrico de la escala en población sana, permitió la estimación de los intervalos de referencia para las cuatro dimensiones, así como los valores para subgrupos conformados por variables demográficas y socioeconómicas, lo que resulta determinante para incluir los desenlaces centrados en las personas en los programas de medicina y salud pública, así como comparadores adecuados para población enferma.
