对于在印度接受白内障手术的患者，现有的患者报告结局（PRO）指标要么不具有文化相关性，要么未经充分验证，要么太长，无法在忙碌的临床环境中使用。我们试图开发和验证一个简短的和文化相关的护理点PRO措施，以满足这一需求。根据初步数据，从印度视觉功能问卷（IND-VFQ）中选择了12个项目。在印度马杜赖的Aravind Eye Care System前瞻性招募18岁及以上的患者。收集临床和社会人口学数据，并在术前和术后对225例患者进行12项简式IND-VFQ（SF-IND-VFQ）;进行因子分析和Rasch建模以评估其心理测量学特性。一个项目，不适合一个一维规模，并与Rasch模型拟合差，从问卷中删除。其余11个项目代表一个单一的结构（没有剩余相关> 0.1），并在很大程度上不受差异项目功能。五个项目的无序阈值解决了崩溃的反应规模从四个到三个类别。问卷具有较好的信度（0.80）、结构效度（不适合范围0.77-1.29;装备范围0.56-1.30）和内容效度（项目分离指数5.87 logits）。测量精度一般（人员分离指数，1.97）。有证据表明，项目并没有最佳地针对患者的视觉能力（术前，-1.92 logits;总体而言，-3.41 logits），尽管调查测量了非常大的影响（科恩的d 1.80）。在一部分患者中，完成问卷调查的平均时间为2分6.3秒。SF-IND-VFQ是一种有效、可靠、灵敏和快速实施的床旁PRO指标，用于评估印度接受白内障手术患者的视觉功能变化。本文的在线版本（10.1186/s12955-018-0855-5）包含补充材料，可供授权用户使用。
For patient undergoing cataract surgery in India, existing patient-reported outcome (PRO) measures are either not culturally relevant, have not been adequately validated, or are too long to be used in a busy clinical setting. We sought to develop and validate a brief and culturally relevant point-of-care PRO measure to address this need. Twelve items from the Indian Visual Functioning Questionnaire (IND-VFQ) were selected based on preliminary data. Patients 18 years and older were prospectively recruited at Aravind Eye Care System in Madurai, India. Clinical and sociodemographic data were collected and the 12-item short-form IND-VFQ (SF-IND-VFQ) was administered pre- and post-operatively to 225 patients; Factor analysis and Rasch modeling was performed to assess its psychometric properties. One item that did not fit a unidimensional scale and had poor fit with the Rasch model was eliminated from the questionnaire. The remaining 11 items represented a single construct (no residual correlations> 0.1) and were largely unaffected by differential item functioning. Five items had disordered thresholds resolved by collapsing the response scale from four to three categories. The survey had adequate reliability (0.80) and good construct (infit range, 0.77–1.29; outfit range, 0.56–1.30) and content (item separation index, 5.87 logits) validity. Measurement precision was fair (person separation index, 1.97). There was evidence that items were not optimally targeted to patients’ visual ability (preoperatively, − 1.92 logits; overall, − 3.41 logits), though the survey measured a very large effect (Cohen’s d 1.80). In a subset of patients, the average time to complete the questionnaire was 2 min 6.3 s. The SF-IND-VFQ is a valid, reliable, sensitive, and rapidly administered point-of-care PRO measure to assess changes in visual functioning in patients undergoing cataract surgery in India.
