Background: The concept of quality of life (QOL) has increasingly
attracted the interest of healthcare providers and is
considered a valid end point for assessing the overall mental
health of patients and their caregivers. Instruments with psychometric
and cross-cultural validity are recommended for
making accurate QOL assessments.
Purpose: The aim of this study was to provide further validation
of the Arabic World Health Organization (WHO)QOL-BREF for
use among family caregivers of relatives with psychiatric illnesses
in Jordan. Of the 26 items that constitute the scale, 24
are in the domains of physical health, psychological health,
social interactions, and environment.
Method: Of the 328 family caregivers approached, data for 266
respondents were kept for analysis. The Arabic WHOQOL-BREF
internal consistency, item internal consistency, item discriminant
validity, and construct validity were evaluated.
Results: The Cronbach_s alpha coefficient was Q0.7. The
24 items constituting the evaluated domains reported an item
internal consistency of Q0.4 and met the item discriminant
validity criterion of having a higher correlation with its corresponding
domain than with other domains. Factor analysis
revealed four strong factors that constituted the same constructs
as in the WHO report.
Conclusions: This study ascertains further validity of the Arabic
WHOQOL-BREF scale for use among family caregivers of
relatives with psychiatric illnesses in Jordan.
