The EUROHIS-QOL 8-Item Index: Comparative Psychometric Properties to Its Parent WHOQOL-BREF

Abstract

The EUROHIS-QOL 8-item index showed acceptable cross-cultural performance and a satisfactory discriminant validity and would be a useful measure to include in studies to assess treatment effectiveness.

Psychometric properties of the EUROHIS-QOL 8-item index (WHOQOL-8) in a Brazilian sample

“…The EUROHIS-QOL 8-item showed similar performance in cross-cultural research conducted in Australia, Brazil, Spain, Israel, Russia, and the United States, where covariance was found between self-esteem and relationship and between relationship and home, as was inverse covariance between general health and finance. 25 Covariance between overall QoL and home and between relationship and self-esteem also appeared in the Portuguese sample. 9 A cross-cultural study for psychometric assessment of the EUROHIS-QOL 8-item index in Romania also found significant model improvement after covarying the items in the environment domain.…”

“…6 This item also had to be deleted to ensure the unidimensionality of the index (as assessed by Rasch analysis) in a cross-cultural study that involved six countries and assessed patients with and without depression. 25 The results of evaluation suggest that this item may have been influenced by cultural differences. The item finance, when excluded from the study carried out in Portugal, greatly increased Cronbach's coefficient.…”

“…This was demonstrated, e.g., by the field research conducted in countries including England, France, Croatia, Czech Republic, Romania, Slovakia, Lithuania, and Latvia, as well as in a further comparative study with the WHOQOLBref involving samples from Australia, Spain, Brazil, Israel, Russia, and the United States. 6,25 Germany, Portugal, New Zealand, and Italy also validated the EUROHIS-QOL 8-item index for use with their populations. [8][9][10][11] The reliability (internal consistency) of the EUROHIS-QOL 8-item, as measured by Cronbach's alpha coefficient, was shown to be excellent, with a total value of 0.81 and no need to exclude any item.…”

“…[19][20][21][22][23][24] Only two studies were conducted in Brazil, where the EUROHIS-QOL 8-item has not yet been evaluated in local samples. 18,25 The objective of the present study was to test the psychometric properties of the EUROHIS-QOL 8-item index in a Brazilian sample. The quality of the instrument was analyzed for reliability (using Cronbach's alpha coefficient), convergent validity (using Pearson correlations of the EUROHIS-QOL 8-item index with other QoL instruments), discriminant validity (comparing the EUROHIS-QOL 8-item measures among a group of sick individuals and a group of healthy controls), factor analysis (using a structural equation model), and unidimensionality (using Rasch model properties)…”

The Indirect Effect of Family Cohesion on Children’s Weight Status Through Maternal Quality of Life and Children’s Internalizing and Externalizing Symptoms

“…This instrument is a quick and practical indicator of overall QoL (Da Rocha, Power, Bushnell, & Fleck, 2012), containing eight items (e.g., "How would you rate your quality of life") answered on a 5-point Likert scale ranging from 1 (not at all/very dissatisfied) to 5 (completely/very satisfied). Higher scores indicate a better perception of QoL.…”
