验证意大利语Catquest-9 SF问卷，评估白内障手术后视力残疾的变化，并确定术前Catquest-9 SF评分与透镜混浊分类系统（LOCS）III白内障分级之间的相关性。前瞻性问卷验证研究。Catquest-9 SF问卷由209名意大利患者在白内障手术前和手术后3个月进行正反翻译和填写。Rasch分析被用来评估其心理测量学特性。意大利Catquest-9 SF表现出有序的反应类别，一维（项目拟合统计范围：0.73-1.34），充分的人分离（2.04），没有差异项目功能。错误明显，项目难度和个人能力的平均差异为2.04 logits，但仅纳入术前数据后有所改善。在有和无眼部合并症的第一次眼部手术和有和无眼部合并症的第二次眼部手术的患者中，视力残疾的平均改善分别为1.92、3.57、1.44和2.94 logits，具有统计学显著性（Friedman检验，p < 0.001）。四组之间的改善无统计学显著差异（Kruskal-Wallis H检验，X2（3）= 5.445，p = 0.142）。Catquest-9 SF评分与核乳光（rs = 0.049，p = 0.478）、核颜色（rs = 0.008，p = 0.909）、皮质（rs = 0.066，p = 0.341）和后囊下成分（rs = 0.048，p = 0.494）之间无相关性。意大利Catquest-9 SF表现出良好的心理测量特性，适用于讲意大利语的患者。有或无眼部合并症的患者接受第一次或第二次眼科手术后视力残疾的改善相似。术前Catquest-9 SF评分与LOCS III白内障分级之间无相关性。
To validate the Catquest-9SF questionnaire in Italian, assess the change in visual disability with cataract surgery and determine the correlation between pre-operative Catquest-9SF scores and Lens Opacities Classification System (LOCS) III cataract grading. Prospective, questionnaire validation study. The Catquest-9SF questionnaire was forward and back translated and completed by 209 Italian patients before and three months following cataract surgery. Rasch analysis was used to assess its psychometric properties. The Italian Catquest-9SF demonstrated ordered response categories, unidimensionality (item fit statistics range: 0.73–1.34), adequate person separation (2.04), and no differential item functioning. Mistargeting was evident with a mean difference in item difficulty and person ability of 2.04 logits but improved with inclusion of pre-operative data only. There was a statistically significant (Friedman tests, p < 0.001) median improvement in visual disability of 1.92, 3.57, 1.44 and 2.94 logits in patients undergoing first eye surgery with and without ocular comorbidity, and second eye surgery with and without ocular comorbidity respectively. There was no statistically significant difference in the improvements among the four groups (Kruskal-Wallis H test, X2(3) = 5.445, p = 0.142). There was no correlation between Catquest-9SF scores and nuclear opalescence (rs = 0.049, p = 0.478), nuclear colour (rs = 0.008, p = 0.909), cortical (rs = 0.066, p = 0.341), and posterior subcapsular components (rs = 0.048, p = 0.494). The Italian Catquest-9SF demonstrated good psychometric properties and is suitable for use in Italian speaking patients. There were similar improvements in visual disability in patients undergoing first or second eye surgery, with or without ocular comorbidity. There was no correlation between pre-operative Catquest-9SF scores and LOCS III cataract grading.
