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.
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.
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).
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.
测试克罗地亚语版慢性静脉功能不全生活质量（CIVIQ）问卷的心理测量特性，并评估各阶段慢性静脉疾病患者的生活质量。
2014年至2015年在一家私人家庭诊所进行的这项横断面研究，评估了由428名成年慢性静脉疾病患者（78%为女性）完成的克罗地亚语版CIVIQ 20项问卷的因子效度、横断面效度和信度，这些患者根据临床-病因-解剖-病理生理（CEAP）C分类被分为C1-C6期。
患者年龄中位数为52岁（第5-95百分位数，30-77岁）。慢性静脉疾病临床分期的分布如下：C1（n=78，18%），C2（n=192，45%），C3（n=53，12%），C4（n=44，10%），C5（n=13，3%），C6（n=48，11%）。CIVIQ-20的因子结构不稳定，为测试简化版（CIVIQ-14）的心理测量特性，从分析中排除了6个项目。CIVIQ-14有三个维度（身体、心理和疼痛）。整个CIVIQ-14的内部一致性信度较高（Cronbach α=0.92），所有CIVIQ-14维度的内部一致性信度也较高（α≥0.80）。随着CEAP C分期升高，生活质量中位数显著下降，如下：C1/C2（86，50-100）；C3/C4（75，36-98）；C5/C6（67，31-95）（P<0.001）。事后分析显示，C1/C期的生活质量高于其他组（P<0.001）。
简化版CIVIQ-14在日常临床实践中有助于评估慢性静脉疾病患者的生活质量。为获得一个稳定的有效工具，我们建议对在多个因子上有载荷的项目进行跨文化验证。
