ABSTRACT
El objetivo de este estudio fue determinar la fiabilidad y la estructura factorial de la versión chilena del WHOQOL-BREF, el cuestionario de la Organización Mundial de la Salud para evaluar la calidad de vida. Una muestra no probabilística de 1205 adultos jóvenes (Medad= 18,6 años; DT= 1,8; 57,8% mujeres) contestaron el WHOQOL-BREF. Usando la matriz de correlaciones policóricas, diferentes modelos fueron estimados y comparados utilizando análisis factorial confirmatorio. Se compararon las puntuaciones según el sexo y el nivel socioeconómico confirmando las hipótesis relativas a la validez de constructo. El modelo bifactor, comparado con un modelo de factores correlacionados y uno de segundo orden, presentó el mejor ajuste a los datos (χ2 [222]= 961,694; p< 0,001; CFI= 0,966; TLI= 0,958; RMSEA= 0,053 [0,049-0,056]). La consistencia interna fue excelente (ω= 0,94). La versión chilena del WHOQOL-BREF tiene propiedades psicométricas robustas, permitiendo la medición de este constructo de forma válida y fiable en adultos jóvenes chilenos (AU)
The objective of this study was to determine the reliability and the factorial structure of the Chilean version scale of quality of life WHOQOL-BREF (World Health Organization). A non-probabilistic sample of 1205 adults (Mage= 18.6, SD= 1.8; 57.8% female) was surveyed during 2018. Using a polychoric correlation matrix, we tested and compared several models with a confirmatory factor analysis. Total scores were compared by sex and socioeconomic status, confirming the hypothesis about the construct validity. A bifactorial model, compared with a correlated factor model and a second-order model, showed better fit indexes (χ2[222]= 961.694, p< .001, CFI= .966, TLI= .958, RMSEA= .053 [.049-.056]). The internal reliability was excellent (ω= .94). The Chilean version of the WHOQOL-BREF is psychometrically sound, allowing to measure this construct reliably and validly in Chilean young adults (AU)

Weight stigmatization is defined as the devaluation of others based on weight, a visible and specific characteristic that cannot be hidden. The consequences of weight stigmatization have been studied in victims and healthcare providers. This narrative literature review describes the consequences of weight stigmatization in victims and healthcare practitioners. According to several studies, high levels of psychological dysfunction in victims coexist with negative stereotypes in healthcare professionals, since the latter are exposed to the same negative media messages about obesity. Thus, weight stigmatization contributes to increase the burden of obesity, since when obese patients perceive that they are discriminated by healthcare professionals, their unhealthy behaviors persist and they have a low adherence to obesity treatment and medical recommendations.
