Development and validation of the Portuguese version of the WHOQOL-OLD module

Abstract

OBJECTIVE:The increasing proportion of older adults in the general population and the specific characteristics of this age group show the need for the development of specific instruments to measure quality of life in older adults. The study aimed at describing the development and validation of the Portuguese version of the World Health Organization Quality of Life for Older Persons (WHOQOL-OLD) module. METHODS:The WHOQOL-OLD instrument was administered in a sample of 424 older adults in the city of Porto Alegre, Southern Brazil, in 2005. The questionnaire comprises 24 items divided into six facets: sensory abilities; autonomy; past, present and future activities; social participation; death and dying; and intimacy. Besides the WHOQOL-OLD module, the WHOQOL-BREF, BDI and BHS instruments were also applied. The instrument's internal consistency was assessed using Cronbach's alpha coefficient. RESULTS:The instrument showed adequate internal consistency (Cronbach's coefficients ranging from 0.71 to 0.88), discriminant validity (p<0.01), concurrent validity (correlation coefficients ranging from -0.61 to -0.50) and test-retest reliability (correlation coefficients ranging from 0.58 to 0.82). Findings concerning criterion validity need further studies. CONCLUSIONS:The WHOQOL-Old module is a useful alternative with good psychometric performance in the investigation of quality of life in older adults.

O objetivo foi descrever o desenvolvimento e a validação da versão em português do módulo específico para idosos do questionário de qualidade de vida (WHOQOL-OLD).

“…16 The validated Brazilian version of the instrument has shown satisfactory psychometric properties: internal consistency (Cronbach's Alpha of 0.71 to 0.88) and test-retest (correlation coefficients between 0.58 and 0.82). 17 The SF-36 version 1 comprises 11 questions and 36 items, gathered in eight domains: functional capacity (ten items); physical aspects (four items); pain (two items); general health status (five items); vitality (four items); social aspects (two items); emotional aspects (three items); mental health (five items) and a comparative question on the perception of health now and a year ago. In each area, the items are added to reflect a scale from 0 (worst health) to 100 (best health) points.…”
