Psychometric properties of the complete version of the World Health Organization Quality of Life Assessment (WHOQOL-OLD): reduced response scale

Abstract

This study sought to compare evidence of the factorial validity of the adapted version of the World Health Organization Quality of Life (WHOQOL-OLD) scale (three response options) with the original version of the scale. We included two populations of individuals age 60 years or older from northeast Brazil. The majority of participants were women who had an elementary-level education. The first population comprised 335 elderly persons who completed the original version of the scale, and the second was composed by 265 elderly persons who completed the shortened scale. Results indicated better adjusting on the reduced scale and showed items with lower error probability in assessment of elderly persons with lower quality of life.

Quality of Life in Older Adults: Evidence from Mexico and Ecuador

“…The Spanish version [ 58 ] of the WHOQOL-OLD Quality of Life Questionnaire from the World Health Organization [ 10 ] was used to measure the quality of life. This questionnaire has been validated in different countries of Europe (e.g., Portugal [ 59 ], Germany [ 60 ], France [ 61 ]), Asia (e.g., Turkey [ 62 ], Iran [ 63 ], China [ 64 ]), Africa (e.g., Ghana [ 65 ]), and Latin America (e.g., Brazil [ 66 , 67 ], Chile [ 68 ], Mexico [ 41 ], Peru [ 69 ]).…”

Instrumentos para la evaluación de la calidad de vida de adultos mayores. Un estudio de revisión bibliográfica

“…En un estudio comparativo realizado en Brasil con 600 personas adultas mayores se evidenció que la fiabilidad del WHOQOL-OLD en su versión original oscilaba entre 0.50 a 0.70 y en su versión reducida oscilaba de 0.52 a 0.77 presentando un mejor ajuste y menor probabilidad de error (De Melo et al, 2018), dentro de un estudio con 120 adultos mayores mexicanos determinaron que el alpha de Cronbach para la versión en español fue de 0.89 y para una muestra de 794 personas de 60 a 89 años, su consistencia interna total alcanzó los 0.84, demostrando ser una herramienta útil dentro de población hispanohablante (Hernández-Navor et al, 2015;Quiroz et al, 2013), en otro estudio con 921 adultos mayores de Portugal la consistencia interna del WHOQOL-OLD tanto en su versión original como en la versión portuguesa europea demostraron excelentes parámetros de fiabilidad y validez (Vilar, Sousa & Simões, 2016); centros de salud pública, residencias de ancianos e investigadores utilizan esta herramienta para medir la calidad de vida de sus adultos mayores en diferentes escenarios y culturas (Bangun, Gondodiputro & Andayani, 2020;Leles da Costa Dias et al, 2019;Amonkar et al, 2018).…”

The importance of anemia and health-related quality of life in the elderly

“…Anemia may cause a decrease in physical functions, such as causing functional limitations and falls. (29)(30)(31)(32) Anemia in the elderly that is not manageable is associated with fatigue, falls, fractures, osteoporosis, increased risk of comorbidities, cardiovascular diseases, functional and mental limitations and death, as well as constituting an economic burden. Although suffering from chronic disease, an elderly person may have a fair degree of health and be able to perform activities of daily living, have a social life and manage finances.…”

“…When quality of life is linked to the context of health and disease, it is usually known as health-related quality of life (HRQoL), to differentiate it from other aspects of quality of life. The World Health Organization (WHO) (32) defines quality of life as "an individual's perception of his/her life situation, that is understood in the context of culture, value system, and in connection with goals, expectations and prevailing standards in a given social environment". From this perspective, HRQoL comprises the areas of physical health, psychological status, degree of individual independence, interpersonal relations, beliefs in the context of special factors or natural environment, and social support that is accepted or felt.…”

“…(39) In health-related quality of life (HRQoL), the approach is multidimensional, comprising the physical, mental, and social aspects that are actually associated with symptoms, incapacity, and limitations that arise because of disease. (32,33) From the results of a literature study carried out by Schnittker and Bacak (40) it was found that the mortality risk was higher in individuals with normal or poor self-rated health than in those with good self-rated health. Although health is an important part of the overall quality of life, there are also other important factors, such as occupation, housing, school and environment.…”
