Abstract |
|
Introduction and
Objectives: The
first quality of
life questionnaire
for Vespula-allergic
patients (Vespid
Allergy Quality of
Life Questionnaire [VQLQ])
was developed in
2002. Our objective
was to perform the
cross-sectional
validation of the
Spanish version of
this questionnaire.
Patients and
Methods: Using
the original
English-language
version of the VQLQ
as a starting point,
the Spanish
translation and
cultural adaptation
were performed and
the first Spanish
version was
backtranslated into
English and
discussed with the
authors of the
original version.
The result was the
Spanish
Health-related
Quality of Life
Questionnaire for
Hymenoptera
VenomAllergic
Patients (HRQLHA).
Cross-sectional
validation was
carried out in a
multicenter study
using a test-retest
design. Patients
over the age of 14
diagnosed with
systemic allergic
reaction to venom
from Apis,
Vespula, or
Polistes species
were included. The
test-retest
reliability,
external validity,
and internal
consistency of the
questionnaire were
measured.
Results: The
sample comprised 116
patients. The mean
HRQLHA score was
3.48. Test-retest
reliability showed
an intraclass
correlation
coefficient of 0.85.
HRQLHA showed a
positive correlation
(0.5) with an
external
questionnaire, thus
demonstrating its
external validity.
Analysis of the
internal consistency
of the HRQLHA
yielded a Cronbach α
of 0.95, which can
be considered to be
excellent.
Conclusions:
Statistical analysis
revealed the high
test-retest
reliability,
internal
consistency, and
external validity of
the HRQLHA. The
HRQLHA is the first
validated
questionnaire to
include patients
allergic to Polistes
species, which is
common in our area.
Our findings show
that the
questionnaire is
also valid for these
patients.
