Sažetak
Aim To test the psychometric properties of the Croatian
version of the Chronic Venous Insufficiency Quality of Life
(CIVIQ) Questionnaire and to assess the quality of life in patients
with chronic venous disorders of all stages.
Methods This cross-sectional study performed between
2014 and 2015 in a private family practice assessed the factorial
validity, cross-sectional validity, and reliability of the
Croatian CIVIQ 20-item questionnaire completed by 428
adult patients (78% women) with chronic venous disorders
classified according to the Clinical-Etiologic-Anatomic-
Pathophysiologic (CEAP) C classification as stages C1-C6.
Results Median patient age was 52 years (5th-95th percentile,
30-77). The distribution according to the clinical
stages of chronic venous disorders was as follows: C1
(n = 78, 18%), C2 (n = 192, 45%), C3 (n = 53, 12%), C4 (n = 44,
10%), C5 (n = 13, 3%), and C6 (n = 48, 11%). The CIVIQ-20
factorial structure was unstable, and six items were excluded
from the analysis to test the psychometric properties
of the shortened version (CIVIQ-14). CIVIQ-14 has three
dimensions (physical, psychological, and pain). Internal
consistency reliability is high for the entire CIVIQ-14 (Cronbach
α = 0.92) and for all CIVIQ-14 dimensions (α≥0.80).
The median quality of life significantly decreased with
higher CEAP C stages as follows: C1/C2 (86, 50-100); C3/
C4 (75, 36-98); C5/C6 (67, 31-95) (P < 0.001). Post-hoc analysis
showed a higher quality of life in C1/C2 than in other
groups (P < 0.001).
Conclusion The shortened CIVIQ-14 version is useful for
assessing the quality of life in patients with chronic venous
disorders in everyday clinical practice. To achieve a
stable validated instrument, we recommend a cross-cultural
validation of items that have loadings on more than
one factor.
